Let's call the average speed for the last three hours "S".
First, we need to find the total distance that Mr. Jackson traveled in the last three hours. He traveled 300 miles in total, and he covered 64 miles in the first 90 minutes, so he had 300 - 64 = 236 miles left to travel.
Next, we need to find the time he spent traveling in the last three hours. If he traveled for three hours, and the first hour he traveled at 66 miles per hour, then he covered 66 miles in the first hour. So, he had 236 - 66 = 170 miles left to travel in the last two hours.
Finally, we can use the formula for average speed: distance divided by time. The total distance he traveled in the last three hours was 170 miles, and the time he spent traveling was 2 hours, so his average speed for the last three hours was:
S = 170 miles / 2 hours = 85 miles per hour
So, Mr. Jackson's average speed for the last three hours was 85 miles per hour.
Answer:
68 mph
Step-by-step explanation:
Let's call the average speed for the last three hours "S".
The total distance traveled for the last three hours is 300 - 64 * 1.5 = 300 - 96 = 204 miles.
So, over the last three hours, Mr. Jackson covered a distance of 204 miles at a speed of S.
The time it took him to cover that distance is 3 hours.
We can use the formula distance = speed * time to find S:
204 = S * 3
Solving for S:
S = 68 mph
So the average speed for the last three hours was 68 mph.

Determine algebraically whether the given function is even, odd, or neither: f(x) = x5 - x3 + x.
Functions are very important concepts in mathematics. There are many types of functions, which include even functions, odd functions, or neither odd nor even functions.
The function f(x) = x⁵ - x³ + x is odd. It satisfies the condition f(-x) = -f(x), making it an odd function.
To determine whether the function f(x) = x⁵ - x³ + x is even, odd, or neither, we need to test if the function satisfies the following conditions for all x:
f(-x) = f(x) for even functions
f(-x) = -f(x) for odd functions
If the function satisfies neither of these conditions, then it is neither even nor odd.
Testing f(-x) = f(x):
f(-x) = (-x)⁵ - (-x)³ + (-x) = -x⁵ + x³ - x
f(x) = x⁵ - x³ + x
Since f(-x) is not equal to f(x), the function is not even.
Testing f(-x) = -f(x):
f(-x) = (-x)⁵ - (-x)³ + (-x) = -x⁵ + x³ - x
-f(x) = -(x⁵ - x³ + x) = -x⁵ + x³ - x
Since f(-x) = -f(x), the function is odd.
Therefore, the given function f(x) = x⁵ - x³ + x is odd.

A sports club has 140 junior members, 695 adult members, and 210 senior members. What is the probability that the first member selected at random will not be a senior member?
Answer: The total number of members in the club is 140 + 695 + 210 = 1,045.
The number of non-senior members is 140 + 695 = 835.
The probability that the first member selected at random will not be a senior member is 835 / 1,045 = 0.798 or 79.8%.
So, the answer is 0.798 or 79.8%.
Step-by-step explanation:
if you randomly select a mechanical component, what is the probability that it weighs more than 11.5lbf
The probability that randomly selected mechanical component weighs: more than 11.5 lbf is 0.0099, less than 8.7 lbf is 0.3208, less than 5.0 lbf is 0.0228, between 6.2 lbf and 7.0 lbf is 0.1314, between 10.3 lbf and 14.0 lbf is 0.0436, between 6.8 lbf and 8.9 lbf is 0.3464.
We can use the standard normal distribution and z-scores to answer these questions:
P(X > 11.5) = P(Z > (11.5 - 8) / 1.5) = P(Z > 2.33) = 0.0099
Therefore, the probability that a randomly selected mechanical component weighs more than 11.5 lbf is 0.0099, or about 1%.
P(X < 8.7) = P(Z < (8.7 - 8) / 1.5) = P(Z < 0.47) = 0.3208
Therefore, the probability that a randomly selected mechanical component weighs less than 8.7 lbf is 0.3208, or about 32%.
P(X < 5.0) = P(Z < (5 - 8) / 1.5) = P(Z < -2) = 0.0228
Therefore, the probability that a randomly selected mechanical component weighs less than 5.0 lbf is 0.0228, or about 2%.
P(6.2 < X < 7.0) = P((6.2 - 8) / 1.5 < Z < (7 - 8) / 1.5) = P(-1.2 < Z < -0.67) = 0.1314
Therefore, the probability that a randomly selected mechanical component weighs between 6.2 lbf and 7.0 lbf is 0.1314, or about 13%.
P(10.3 < X < 14.0) = P((10.3 - 8) / 1.5 < Z < (14 - 8) / 1.5) = P(1.53 < Z < 2.67) = 0.0436
Therefore, the probability that a randomly selected mechanical component weighs between 10.3 lbf and 14.0 lbf is 0.0436, or about 4%.
P(6.8 < X < 8.9) = P((6.8 - 8) / 1.5 < Z < (8.9 - 8) / 1.5) = P(-0.47 < Z < 0.60) = 0.3464
Therefore, the probability that a randomly selected mechanical component weighs between 6.8 lbf and 8.9 lbf is 0.3464, or about 35%.

The midpoint of GH is (1,-4). The coordinates of point G are (3,-5).
What are the coordinates of point H?
The coordinates of point H are (-1,-3). This is obtained by using the midpoint formula and solving for the coordinates of point H, given the midpoint of GH and the coordinates of point G.
To find the coordinates of point H, we can use the midpoint formula, which states that the midpoint of a line segment is the average of the coordinates of its endpoints.
If the midpoint of GH is (1,-4) and the coordinates of point G are (3,-5), we can write: (1,-4) = [(3 + x)/2, (-5 + y)/2]
where x and y are the coordinates of point H. We can solve for x and y as follows:
2(1,-4) = (3 + x, -5 + y)
(2, -8) = (3 + x, -5 + y)
2 = 3 + x --> x = -1
-8 = -5 + y --> y = -3
Therefore, the coordinates of point H are (-1, -3).

What are Congruent triangles?
When all three corresponding sides are the same length and all three corresponding angles are the same size, two triangles are said to be congruent.
Given, ΔLMN ≅ ΔRST,
So, ∠L = ∠R = 49
∠M = ∠S = 70
∠N = ∠T = 4y + 9
Now, In triangle RST,
∠R + ∠S + ∠T = 180 ( sum of all angles of a triangle is 180 )
49 + 70 + ∠T = 180
∴ ∠T = 61 = ∠N
and, 4y + 9 = 61
y = 13.
Now, In triangle LMN ,
∠L + ∠M + ∠N = 180
49 + 10x + 61 = 180

A stamp book contains a mixture of 27c second class stamps and 32c first class stamps. The
total value of stamps in the book is exactly $6.00.
How many 27c stamps are there in the book?
A 5
B 8
C 10
D 12
E 22
Answer:
8
Step-by-step explanation:
Let's call the number of 27c stamps in the book "x". The number of 32c stamps in the book would then be $6.00 / $0.32 = 18.75 stamps, but since stamps come in whole numbers, we'll round down to 18 stamps. So the total number of stamps in the book is x + 18.
The total value of the 27c stamps is $0.27 * x. The total value of the 32c stamps is $0.32 * 18 = $5.76. The total value of both stamp types is $6.00, so we have the following equation:
$0.27x + $5.76 = $6.00
Solving for x:
$0.27x = $0.24
x = $0.24 / $0.27 = 8.89 stamps, rounded down to the nearest whole number, which is 8 stamps.
So the answer is B) 8.
suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.61 and a standard deviation of 0.41 . using the empirical rule, what percentage of the students have grade point averages that are between 1.38 and 3.84 ?
By empirical rule, 99.7% of the students have a grade point average which is between 1.38 and 3.84.
Suppose that the grade point average of undergraduate students at one university has a bell-shaped distribution with a mean of 2.61 and a standard deviation of 0.41.
Here, μ = 2.61 , σ = 0.41
Using the empirical rule :
The first part of the empirical rule states that 68% of the data values will fall within 1 standard deviation of the mean. To calculate "within 1 standard deviation," you need to subtract 1 standard deviation from the mean, then add 1 standard deviation to the mean. That will give you the range for 68% of the data values.
2.61 − 0.41 = 2.2
2.61 + 0.41 = 3.02
The range of numbers is 2.2 to 3.02
The second part of the empirical rule states that 95% of the data values will fall within 2 standard deviations of the mean. To calculate "within 2 standard deviations," you need to subtract 2 standard deviations from the mean, then add 2 standard deviations to the mean. That will give you the range for 95% of the data values.
2.61 − 2(0.41) = 1.79
2.61 + 2(0.41) = 3.43
The range of numbers is 1.79 to 3.43
Finally, the last part of the empirical rule states that 99.7% of the data values will fall within 3 standard deviations of the mean. To calculate "within 3 standard deviations," you need to subtract 3 standard deviations from the mean, then add 3 standard deviations to the mean. That will give you the range for 99.7% of the data values.
2.61 − 3(0.41) = 1.38
2.61+3(0.41) = 3.84
The range of numbers is 1.38 to 3.84.
Hence, 99.7% of the students have a grade point average which is between 1.38 and 3.84.

An office is planning to divide a common area into a social area and a quiet area. The quiet area takes up one-third of the space. The architect draws this plan at a scale of 1 ft.: 4 cm. What is the area of the social area on the plan?
Answer:
Let's call the total area of the common space "A". Since the quiet area takes up one-third of the space, its area is A/3.
The scale of the plan is 1 ft.: 4 cm, which means that one foot on the plan represents 4 cm in real life. So, the area of the social area on the plan is 4 times smaller than the actual area of the social space.
Therefore, the actual area of the social space is (A - A/3) = 2A/3. And the area of the social area on the plan is (2A/3) / 4.
Area of the social area on the plan is (2A/3) / 4.
Here,
Let the total area of the common space "A".

There are 180 different starting lineups that can be created for the college team.To find the number of different starting lineups that can be created for the college team, we need to use the combination formula.
The number of ways to choose k items from a set of n distinct items is given by the formula:
nCk = n! / (k! * (n-k)!)
where "!" denotes the factorial function, which means the product of all positive integers up to that number.
In this case, we want to choose 2 guards out of 5, 2 forwards out of 4, and 1 center out of 3. So the total number of different starting lineups that can be created is:
(5C2) * (4C2) * (3C1)
= (5! / (2! * 3!)) * (4! / (2! * 2!)) * (3! / (1! * 2!))

a variable x has standard deviation 10 and variable y has standard deviation 5. if their covariance is 25, what is the correlation between x and y?
The correlation between x and y is 0.5. This indicates a positive correlation, meaning that as values of x increase, so do the values of y.
The correlation coefficient (denoted by ρ) between x and y can be calculated as:
ρ = covariance(x,y) / (standard deviation of x * standard deviation of y)
A measure of the link between two random variables and how much they fluctuate together is called covariance. Alternately, we may say that it establishes the relationship between the two variables' changes, i.e., that a change in one variable is equivalent to a change in the other. When the variables are translated linearly, a function has the property of preserving its shape.
We are given that the covariance between x and y is 25, the standard deviation of x is 10, and the standard deviation of y is 5. Substituting these values into the formula, we get:
ρ = 25 / (10 * 5) = 0.5

At the balloon dart booth, players are charged $1 for the chance to throw 3 darts, Prizes worth $4 each are awarded to players who pop at least 2 balloons. Last year, 4 out of 12 players popped 2 balloons, and 1 out of 12 players popped 3 balloons.
If the ratio of winners to players remains the same as last year, the balloon dart booth can expect to have 85 winners among 204 players and lose $136.
A ratio compares two quantities or values. In this case, the ratio we are interested in is the ratio of winners to players.
Last year, out of 12 players, 4 popped 2 balloons and 1 player popped 3 balloons. Therefore, the total number of players who won prizes was 4+1=5. The ratio of winners to players is 5/12.
To calculate the number of winners this year, we can use the same ratio. If we assume that the ratio of winners to players is constant, we can set up the following proportion:
(winners/players) = (5/12)
Let's solve for the number of winners among 204 players:
(winners/204) = (5/12)
winners = (5/12) * 204
winners = 85
Therefore, we can expect 85 winners among 204 players if the ratio of winners to players remains the same as last year.
Now let's calculate the potential earnings or losses for the booth. Each player pays $1 for three darts, so the booth will earn 204*1 = $204.
Out of the 204 players, we expect 85 winners. Each winner receives a prize worth $4, so the total cost of prizes is 85*4 = $340.
The booth earns $204 and spends $340 on prizes, resulting in a loss of $136.

dilate figure abcd by a scale factor of 3 with the center of dilation at the origin
The dilated figure coordinates will be A(-6,6); B(3,3); C(3,-3); D(-3,0) E.g. If a figure is drawn by the help of lines and the length of all the four lines are equal, then the resultant figure is known as Square Shape.
What are the dilate figures?Figures are nothing but a kind of drawing which we make using lines and arcs. Figures can be 2-D or 3-D. In mathematics these figures are studied by calculating their's area, perimeter, surface area, volume, etc.
In mathematics when we draw a figure using line and arcs and the resultant figure has some specific pre-defined properties then such figures are called shapes.
The coordinates of the given figure ABCD are
A=(-2,2); B=(1,1); C=(1,-1) and D=(-1,0)
As we have to dilate the figure by the factor of 3 from the origin which means we have to enlarge the figure 3 times with same origin, then we simply multiply the coordinates of the given figure by 3.
Dilated coordinates will be
A=(-2×3,2×3)=(-6,6)
B=(1×3,1×3)=(3,3)
C=(1×3,-1×3)=(3,-3)
D=(-1×3,0×3)=(-3,0)
Therefore, New dilated coordinates of the figure are A(-6,6); B(3,3); C(3,-3) and D(-3,0).
