Answer:
g(3a – 6) = a - 4
Step-by-step explanation:
g(x) = 1/3x - 2
g(3a – 6) = 1/3(3a – 6) - 2
= a - 2 - 2
= a - 4
Answer:
g(3a - 6) = a - 4
Step-by-step explanation:
If you start with g(x) = 1/3 x - 2
Then whatever x = on the left, must take on the value on the right.
g(3a - 6) = 1/3 (3a - 6) - 2 Notice the x is gone and 3a - 6 has taken it's place.
Now you must distribute the 1/3 for both 2a and 6
g(3a - 6) = 1/3 * 3a - 1/3 * 6 - 2
g(3a - 6) = a - 2 - 2
g(3a - 6) = a - 4

A farm has 6 chickens, 4 ducks, 2 pigs and 4 cows. If an animal is chosen at random, find P(Cow | 2 legs)
The conditional probability P(Cow | 2 legs) is 0.
We have,
To find the conditional probability of selecting a cow given that the animal has 2 legs, we need to determine the number of 2-legged animals and the number of cows with 2 legs.
From the given information, we know that cows have 4 legs.
The probability of selecting a cow with 2 legs is 0, since cows do not have 2 legs.
Thus,
The conditional probability P(Cow | 2 legs) is 0.

For my
mom's new exercise program, every two days she jogs two miles and every 5 days lifts
weights. On what day will she jog and lift weights on the same day?
Answer:
She will jog and lift weights on the same day in 10 days
Step-by-step explanation:
To find when two events will happen on the same day, we find the least common multiple(that is not 0) of their frequencies.
In this question:
Every two days she jogs
Every 5 days she lifts.
Multiples of 2: {0, 2, 4, 6, 8, 10, 12, ...}
Multipled of 5: {0, 5, 10, 15, ...}
The least common multiple is 10, so:
She will jog and lift weights on the same day in 10 days
Find the measure of angle M

Answer:
136°Step-by-step explanation:
Since the trapezoid is isosceles, the angles J and M are supplementary and angles M and L are congruent, therefore:
∠J + ∠M = 180°∠J + ∠L = 180°7x + 2 + 25x - 14 = 180°32x = 192x = 192/32x = 6∠M = ∠L = 25*6 - 14° = 150° - 14° = 136°
Answer:
From the given figure we can see that :---
JK||ML, JK=ML and JM=KL
Therefore,
angle J+ angle L = 180°
[tex](7x + 2) + (25x - 14) = 180 \\ 32x - 12 = 180 \\ 32x = 192 \\ \boxed{x = 6}[/tex]
Now, we know that, angle M = angle L
Hence,
[tex]25x - 14 \\ =( 25 \times 6) - 14 \\ =150 - 14 \\ = \boxed{136}[/tex]
Angle M is 136°.A line is drawn through the points $(-2, 6)$ and $(-4, -2)$. What is the $y$-coordinate of the point where this line intersects the $y$-axis?
Answer:
This line intersects the y-axis at [tex]y = 14[/tex]
Step-by-step explanation:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept(point where the line intersects the y-axis).
To find the slope, we take two points, and the slope is given by the change in y divided by the change in x.
In this question:
Points (-2,6) and (-4,-2). So
Change in y: -2 - 6 = -8
Change in x: -4 -(-2) = -4 + 2 = -2
Slope: [tex]m = \frac{-8}{-2} = 4[/tex]
So [tex]y = 4x + b[/tex]
Now, we take a point, and find b.
Point (-2,6), which means that when [tex]x = -2, y = 6[/tex]. So
[tex]y = 4x + b[/tex]
[tex]6 = 4(-2) + b[/tex]
[tex]b = 14[/tex]
So this line intersects the y-axis at [tex]y = 14[/tex]
A family of 4 is buying cell phones. Each phone costs x dollars if the family buys the super plan which costs $89 for
each family member. The total cost for each family member to have a phone with the super plan is $1,952
Part A
Which equation represents this situation?
O4(2 + 89) = 1,952
O (x + 89) + 4 = 1,952
4x + 89 = 1,952
O 4x(89) = 1,952
Part B
What is the cost, in dollars, of each phone?
Each phone costs $
Ya
Answer: See explanation
Step-by-step explanation:.
From the question, the equation to illustrate the above question will be:
4(x + 89) = 1952
We can then solve further to get the value of x which will be:
4x + 356 = 1952
4x = 1952 - 356
4x = 1596
x = 1596/4
x = 399
Each phone cost $399
Select the correct answer. What is the solution to this equation?
324=4(3)2x
a. x=8
b. x=4
c. x=2
d. x = 1
Answer
C. x=2
Step-by-step explanation:
This is due to 2(2) = 4
then 3^4=81
81*4=324
The solution to equation [tex]324=4(3)^{2x}[/tex] is x = 2.
What is exponential function?An exponential function is a mathematical function of the following form:
[tex]f(x) = a^{x}[/tex]. where x is a variable, and a is a constant called the base of the function.
Given exponential equation
[tex]324=4(3)^{2x}[/tex]
[tex]4(3)^{2x}=324[/tex]
[tex]3^{2x} =\frac{324}{4}[/tex]
[tex]3^{2x}=81[/tex]
[tex]3^{2x}=3^{4}[/tex]
When bases are equal, power should be equal.
2x = 4
x = 2
Hence, the solution to equation [tex]324=4(3)^{2x}[/tex] is x = 2.
Option C is correct.

A computer’s random number generator produces random integers from 1 to 50. What is the probability that the first 3 integers generated are single-digit numbers?
0.0058
0.0080
0.5120
0.5514
Answer:
0.0058
Step-by-step explanation:
Probability is defined as the ratio of the possible outcome to the total outcome. The number of single-digit numbers between 1 and 50 is 9 ( from 1 to 9). As such, the probability of generating a single digit integer is
P(single) = 9/50
The probability that the first 3 integers generated are single-digit numbers
= 9/50 * 9/50 * 9/50
= 0.18 * 0.18 * 0.18
= 0.005832
This may be approximated to 0.0058

2.5+3.5=6 yards
6+3.5 ft=9.5 yards
9 yards 1 foot 2 inches
took me forever to write this
Answer:
342 inches, 28.5 feet, 9.5 yards.
Step-by-step explanation:
The conversion rates you need to know are as follows:
1 foot = 12 inches
1 yard = 3 feet
Because there are 3 feet in a yard, we know that there must be are 36 inches in a yard. First, we find how many inches are in 10.5 feet and 3.5 yards. This would be 10.5 * 12 resulting in 126 inches. Also, 3.5 yards as we know is 36 inches so we do 3.5 * 36 which results again in 126. Finding the sum (126 + 126 + 90) we can see that this ribbon is 342 inches long. To find feet we divide this by 12. To find yards, we divide it by 36.

Tyion has 4,000 dollars and wants to share it evenly with 19 friends. How much would they each receive?
Answer:
Each friend will receive 210.5 dollars.
Step-by-step explanation:
Total Amount Tyion has = 4,000 dollars
He wants to share evenly with 19 friends.
We need to find How much would amount each friend will receive.
We can found it by using formula:
Amount each friend received = Total Amount / Number of friends
Putting values in the formula and finding results:
Amount each friend received = 4000/19
Amount each friend received = 210.5 dollars
So, each friend will receive 210.5 dollars.

Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
The population is divided into groups(by stores), and all elements of the groups(all customers at the stores are sampled), which is the characteristic of a cluster sampling.
