Bob 's daily commute time is randomly distributed with a minimum of 20 minutes, a maximum of 61 minutes, and the most common length is 30 minutes. What is the probability that his commute today took more than 35 minutes?
Answer:
0.6341 = 63.41% probability that his commute today took more than 35 minutes
Step-by-step explanation:
Randomly distributed = Uniform distribution.
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
Randomly distributed with a minimum of 20 minutes, a maximum of 61 minutes.
This means that [tex]a = 20, b = 61[/tex].
What is the probability that his commute today took more than 35 minutes?
[tex]P(X > 35) = \frac{61 - 35}{61 - 20} = 0.6341[/tex]
0.6341 = 63.41% probability that his commute today took more than 35 minutes
Explain what it means to be a solution when there are two lines on a graph
Answer:
Step-by-step explanation:
When the lines intersect, the point of intersection is the only point that the two graphs have in common. So the coordinates of that point are the solution for the two variables used in the equations.
teresa says the two expressions below are equivalent: 2(5x-3) + 6x and 16x -3 is teresa correct? Explain why or why not
Answer:
No.
Step-by-step explanation:
2(5x-3) + 6x is equal to 16x-6:
Distribute:
=(2)(5x)+(2)(−3)+6x
=10x+−6+6x
Combine Like Terms:
=10x+−6+6x
=(10x+6x)+(−6)
=16x+−6,
Which is not equal to 16x-3
find the value of x. inscribed angles
9514 1404 393
Answer:
x = 33°
Step-by-step explanation:
The value of an inscribed angle is half the value of the arc it subtends.
The angle marked x subtends the arc marked 66°, so has a value of ...
x = 66°/2
x = 33°
_____
The value of y is similarly found.
y = 96°/2
y = 48°
__
The angle marked with a dot is an external angle of the triangle, so is the sum of the remote internal angles, x and y:
dot angle = x + y = 33° +48° = 81°
Of course, angle z is the supplement of this:
z = 180° -81°
z = 99°
Answer:
x=33
Step-by-step explanation:
The answer would be x=33
Find the measure of one interior angle in each regular polygon. Plz
Answer:
108°
Step-by-step explanation:
If regular polygon has n sides, then each interior angle = 180° - (360/n)°.
When n = 5, interior angle = 180° - (360/5)° = 108°
in the first week of July, a record 1,040 people went to the local swimming pool. In the
second week, 100 fewer people went to the pool than in the first week. In the third week, 130 more
people went to the pool than in the second week. In the fourth week, 290 fewer people went to the
pool than in the third week. What is the percent decrease in the number of people who went to the
pool over these four weeks?
Answer: 25%
Step-by-step explanation:
First week of July = 1040 people
Fourth week of July = 1040- 100 + 130 - 290 = 780
The number of people that went to the swimming pool in 1st week was 1040 while the 4th week had 780. The percentage decrease will be:
= (1040 - 780) / 1040 × 100
= (260 / 1040) × 100
= 0.25 × 100
= 25%
Combine like terms to simplify the expression below 5y - 8x - y + 12x
Answer:
4x + 4y
Step-by-step explanation:
5y - 8x - y + 12x
4y + 4x
Answer:
4y + 4x
Step-by-step explanation:
There are 4 terms in the equation 5y - 8x - y + 12x: 5y, -8x, -y, and 12x. WE have to add like terms to make a simplified equation. 5y and -y are alike, as are -8x and 12x. Subtract 1y from 5y to get 4y. Add 12x to -8x to get +4x. As a result, the expression becomes 4y + 4x.

Anybody know this? I need some help
Answer:
17
Step-by-step explanation:
First, you can change the equation to 12 1/2 + 4 1/2, as subtracting a negative number is actually adding it. Then, if easier, the mixed numbers can be changed to improper fractions -- 12 1/2 = 25/2 and 4 1/2 = 9/2. Then add; 25/2 + 9/2 = 34/2, and 34 divided by 2 is 17.

A TV is measured by its diagonal. If the height of a 60 inch
TV is 32 inches, what is the width?
Given :
A T.V. is measure by its diagonal.
To Find :
If the height of a 60 inch T.V. is 32 inches, what is the width.
Solution :
We know, T.V. is rectangular in shape and angle between two sides of rectangular is 90° .
Let, width of T.V. is x.
Applying Pythagoras theorem in sides, we get :
[tex]height^2 + width^2 = hypotenuse^2\\\\23^2 + x^2 = 60^2\\\\x = \sqrt{3600 -529 }\\\\x = 55.42 \ inches[/tex]
Therefore, width of T.V. is 55.42 inches.

Step 7: Substitute values into y = mx + b
Step 8: Write answer y =
x +
Answer:
y = 4x + 3
Step-by-step explanation:
Step 1: Write the general equation
y = mx + b
Step 2: Identify b, the Y intercept (x = 0)
b is the value of y when x = 0.
From the graph, when x = 0, y = 3.
Therefore, b = 3
Step 3: The second point from graph (x, y):
P = (1, 7)
Step 4: Define m as ratio of rise / run:
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Step 5: Put coordinates into ratio:
Using the two coordinates, (0, 3) and (1, 7), we would have,
[tex] m = \frac{7 - 3}{1 - 0} [/tex]
Step 6: Perform subtraction to get slope:
[tex] m = \frac{4}{1} [/tex]
m = 4
Step 7: Substitute values into y = mx + b:
Thus, plug in the values of m and b into the slope-intercept equation.
b = 3, m = 4, therefore:
y = (4)x + (3)
Step 8: Write answer:
y = 4x + 3

. Brian can pick forty-five pounds of strawberries in six hours. If he works two ten-hour days, how many pounds of strawberries will he be able to pick?
Answer:
over 120 i think
Step-by-step explanation:
1. this is the first way to do it: because if he can pick 40 pounds in 6 hours and he worked for about 20 hours that if you divide 20 by 6 you will get three because 6x3=18 hours and 40x3= 120
2. the second way is when you subtrat 6-10 and get 4 leftover and if you do that twice you get 8 leftover in all and if you do 8-6 it is 2 leftover so in all you have you have three six hours out of 20 and so you would have to multiply 40 times 3 because every six is 40 pounds of strawberries.

Alex asked her friend Beau to bring his robots to the fair. Guests can buy tickets to play with the robots. Beau needs to rope off an area to the fair grounds keep his robots in sight. Read his notes.
The area should be rectangular.
It needs to more then 100 feet long and less then 100 feet wide
The area needs to be between 7,500 and 10,000 square feet
Answer:
length = 100< l > 150
breadth = 50 < b> 100
Step-by-step explanation:
The area of the rectangle is given by the formula
Area= Length * Breadth
A= L*B
Suppose both the length and the breadth are 100 feet then the area would become
A= 100*100= 10,000 square feet.
The length and the breadth of the square are equal in size and we dont need a square we need a rectangle therefore these values cannot be inclusive for lenght and breadth.
It is given that the length is longer than 100 feet and breadth is shorter than 100 feet.Therefore
length can be 110 feet and breadth 90 feet
Again the area = A= l*b = 110 *90= 9,900 square feet.
Similarly putting different value from 50 to 150 feet for breadth and length we can obtain different results .
Area = l*b = 150*50 = 7500 square feet
for all values of the length between 100 to 150 feet and for breadth 50- 100 feet we can have the values of the area between 7500 to 10,000 square feet.
length = 100< l > 150
breadth = 50 < b> 100

a linear equation is an equation in which the highest order of exponent is 1.
your equation is:
4x - y = 7
it's a linear equation.
none of the variables has an exponent larger than 1.
x = x^1
y = y^1
to find your ordered pairs, just take 3 values for x at random and plug them into the equation.
let x = 1,2,3
your equation is:
4x - y = 7
if you solve for y, it makes it easier to find the y value given the x value.
solve for y to get:
y = 4x - 7
when x = 1, y = -3
when x = 2, y = 1
when x = 3, y = 5
placing the equation into this form also allows you to graph it.
placing the equation into this form also gives you the slope-intercept form of the equation.
what you started with was the standard form of the equation for a straight line.
that standard form is ax + by = c
your equation is:
4x - y = 7
a = 4 and b = -1
the slope intercept form of the equation of a straight line is y = mx + b
m is the slope and b is the y intercept.
when you solved for y, you placed the equation into this form.
your slope is 4
your y intercept is -7

I placed horizontal lines at y = -3, 1, 5.
If you trace a vertical line down from the intersections of those lines with the line created by your equation, you will see that the value of x at those intersection points is 1,2,3
the points on the line formed by your equation are:
(x1,y1) = (1,-3)
(x2,y2) = (2,1)
(x3,y3) = (3,5)
you can take any other values of x and find the corresponding value of y by just replacing x in the equation with the value of x.
the equation is y = 4x - 7
when x = 5, y = 20-7 = 13, etc. brainlest pls
