The given information is:

- The average test score is 85 points

- The standard deviation is 9

- It is a normal distribution

We need to find the best estimate for the proportion of students earned a 70 points or higher.

First, we need to find the z-score for 70, by applying the following formula:

Then, as x=70, we replace the given values and find z:

Then, we can find the estimate as follows:

Now, in a standard normal table, we search the cumulative probability of z<-1.67, and it is 0.0475:

Thus, replace this value to find P(X>=70):

The probability is 0.9525, if we multiply it by 100%, we obtain: 95.25%

The best estimate is 95%.

Answer:

total is 13. so 5+6 = 11 and total is 13 so 13 - 11 = 2

First, determine the speed of Arielle by calculating the quotient in between 55 ft and 2 3/4 minutes. To find the quotient, convert the mixed number to a normal fraction before:

then, calculate the speed:

then, the Arielle's speed is 15 ft/min

next, find the distance traveled by Arielle in 15 min, by using the previous result:

Hence, in relation to the rim, Arielle will be at 225 ft

Step-by-step explanation:

the perimeter of a triangle is 84 cm and its area is 36 CM square if one its side is 30 cm find the length of remaining two side

The area of the walkway in square yards is 22.77 yards²

The cost of painting the walkway will be $85.37.

The square yards of the walkway can be determined by adding the areas of the two rectangles and the area of the quarter of a circle together.

Area of a rectangle = length x width

Area of the first rectangle = 9.5 x 1.5 = 14.25 yards²

Area of the second rectangle = 4.5 x 1.5 = 6.75 yards²

Area of a circle = πr²

Area of quarter of a circle = 1/4 ×  πr²

Where:

π = pi = 3.14

r = radius

1/4 x (3.14 x 1.5²) = 1.77 yards²

Area of the walkway = 1.77 yards² + 6.75 yards² +  14.25 yards² = 22.77 yards²

The cost of the painting can be determined by multiplying the area of the walkway by the cost per square yard.

Total cost = 22.77 yards² x 3.75 = $85.37

Step-by-step explanation:

To help, but not give the answer so you can learn to do this:

To find the slope, choose any two points on the graph (no really IT DOESN'T MATTER WHICH ONE). Use the equation y-y/x-x to get the slope.

Ex. 8-3/5-1=4/3

(NOTE: Always write your answer as either an improper fraction or a whole number!)

To find the distance, go across the x-axis, however many units away the closest point is to your chosen point. Then, go across the y-axis for the required # of units. Next, find the total number of the x and y units. You can also subtract the smallest coordinate from the greatest if the two ordered pairs are in the same quadrant. If not in the same quadrant, add the coordinates together. If the value of x or y happens to be the same as your chosen coordinate, find the sum of the two numbers that are equal, or subtract if in the same quadrant.

Also, in case you have another question relating to the same line, the given line is NOT proportional. Just in case, though!

I hope this helps you with your question!

For the give question;

The given line is; -2x + 3y = 6

Write the equation in slope intercept form; y = mx + c.

-2x + 3y = 6

3y = 2x + 6

y = (2/3)x + 2

Slope m₁ = 2/3 and y intercept is 2.

For the relation of slope;

Part a: -3x - 2y = 4

Write  the equation in slope intercept form;

-2y = 3x + 4

y = (-3/2)x - 2

m₂ = -3/2

m₁ ≠ m₂ as 2/3  ≠ -3/2

m₁×m₂ = 2/3 × -3/2 = -1

Thus, the both lines are perpendicular.

Part b: -2x + 3 y = -6

Write  the equation in slope intercept form;

3y = 2x - 6

y = (2/3)x - 2

m₂ = (2/3)

m₁ = m₂

Thus, both lines are parallel.

Part c: 2x + 3y = 6

Write  the equation in slope intercept form;

3y = -2x + 6

y = (-2/3)x + 2

m₂ = -2/3

m₁ ≠ m₂ as 2/3  ≠ -2/3

And,  m₁×m₂ = 2/3 × -2/3 ≠ 1

Thus, lines are neither parallel not perpendicular.

Part d: -2x + 3y = 0

Write  the equation in slope intercept form;

3y = 2x

y = 2/3 x

m₂ = 2/3

m₁ = m₂

Thus, both lines are parallel.

Answer: The lungs provide the airstream which powers human voice. As air is pushed up the windpipe from the lungs, the larynx, which is made up of two vocal folds, opens and closes to produce vibrations. These vibrations are carried through to the throat, nose, and mouth, which act as resonators- morphing the vibrations into distinct human sounds.

Step-by-step explanation:

Answer:

Our vocal cords gve us our voice.

Step-by-step explanation:

The vocal folds (cords) produce sound when they come together and then vibrate as air passes through them during exhalation of air from the lungs.  This vibration produces the sound wave for your voice.  

Based on the time the clock is set to, and the minutes lost every hour, the time the clock would show the next day at 10 am is 8:57 am

To find the time that the clock would show the next day, first find the difference between the 1 pm and 10 am the next day:

This difference is:

= 10 am the next day - 1 pm

= 10 + (12 - 1)

= 10 + 11

= 21 hours

The number of minutes lost is:

= 21 x 3 minutes per hour

= 63 minutes

The time the clock would be showing is:
= 10 am  - 63 minutes

= 8:57 am

Step-by-step explanation:

rational no. simply means a fraction.

The addition of the fraction 1/10 + 11/20 based on the computation will be 13/20.

In mathematics, a fraction is defined as a portion of the whole. If a pizza is cut into four equal pieces, each slice is represented by ¼.

It should be noted that a fraction simply means a part of a whole number. It should be noted that it's usually expressed as a/b where a is the numerator and b is the denominator.

In this case, we want to add 1/10 + 11/20. This will be illustrated thus:

= 1/10 + 11/20

= 2/20 + 11/20

= 13/20

Therefore the addition is 13/20.

As a result, we deduce that 101 tickets were sold to adults and 171 to students after solving the algebraic equations.

The term "algebraic equation" refers to a formulation of the equality of two expressions using the algebraic operations of addition, subtraction, multiplication, division, raising to a power, and extraction of a root on a set of variables.

A mathematical statement in which two expressions are rendered equal to one another is known as an algebraic equation.

So on the information provided to us:

we know that the total amount of the tickets sold =1694$

total no. of people = 272

Lets assume the no. of kids to be y and the adults to be x

So the first equation we get for the total no. of people is:

x+y=272...(i)

the next equation we get for the total amount of tickets sold will be equal to the no. of adults and  children multiplied by the cost of each adult and child respectively :
7x+4y=1694....(ii)

Two solve both equations simultaneously , we multiply equation i with 4

we get:

4x+4y=1088

7x+4y=1694

on solving both the equations simultaneously we get

3x=606

x=101

putting value of x in equation (i) we get

y=171

Therefore, we conclude that the no. of tickets sold to adults were 101 and to students were 171.

The unit rate of what Sarah bought is 0.8 dollars per pepper.

The equation relating cost in dollars, c to the number of red peppers is c = 0.8p

A unit rate describes the ratio of two different units for the quantity of one.

In other words, the unit rate can be defined as the ratio between two measurements with the second term as 1.

Therefore, the unit rate when Sara buys 7 red peppers for $5.60 can be calculated as  follows

unit rate = cost of pepper / number of pepper

unit rate = 5.60 / 7

unit rate = 0.8 dollars per pepper

Let's use the unit rate to write an equation relating the cost in dollars c to the number of red peppers, p.

The values of the trigonometry formulas are sin(240) = -sin(60), cos(225) = -cos(45) and tan(225) = tan(45)

The trigonometry ratios are given as

sin(180 - ∅) = sin(∅)

cos(180 - ∅) = -cos(∅)

tan(180 - ∅) = -tan(∅)

Also, we have the following trigonometry ratios are given as

sin(180 + ∅) = -sin(∅)

cos(180 + ∅) = -cos(∅)

tan(180 + ∅) = tan(∅)

Using the above trigonometry ratios, we  have

sin(240) = sin(180 + 60)

By comparison, we have

sin(240) = sin(180 + 60)

sin(180 + ∅) = -sin(∅)

This gives

∅ = 60

So, we have

sin(180 + 60) = -sin(60)

Evaluate

sin(240) = -sin(60)

Using the above trigonometry ratios, we  have

cos(225) = cos(180 + 45)

By comparison, we have

cos(225) = cos(180 + 45)

cos(180 + ∅) = -cos(∅)

This gives

∅ = 45

So, we have

cos(180 + 45) = -cos(45)

Evaluate

cos(225) = -cos(45)

Using the above trigonometry ratios, we  have

tan(225) = tan(180 + 45)

By comparison, we have

tan(225) = tan(180 + 45)

tan(180 + ∅) = tan(∅)

This gives

∅ = 45

So, we have

tan(180 + 45) = tan(45)

Evaluate

tan(225) = tan(45)
