1. When Aaron runs the 400 meter dash, his finishing times are normally distributed with a mean of 80 seconds and a standard deviation of 2.5 seconds. Using the empirical rule, determine the interval of times that represents the middle 99.7% of his finishing times in the 400 meter race.
Answer:
(72.5,87.5)
Step-by-step explanation:
The interval of times that represents the middle 99.7% of his finishing times in the 400 meter race is; (73.5, 87.5)
What is the interval from empirical rule?
We are given;
Mean; E(X) = μ = 80 seconds
Standard Deviation; σ = 2.5
From the empirical rule, the probability of obtaining values within one deviation from the mean is 0.68; within two deviations is 0.95 and within 3 deviations from the mean is 0.997.
We have 99.7 % of the values within 3 deviations from the mean in our question and so the intervals are;
μ - 3σ = 80 - 3(2.5) = 73.5
μ + 3σ = 80 + 3(2.5) = 87.5

Priya and Han plan a fundraiser for the running club. They begin with a balance of -80 because of expenses. In the first hour of the fundraiser they collect equal donations from 9 parents, which brings their balance to -44. How much did each parent give?
Answer: 4
Step-by-step explanation:
First we need to find the difference of the balance.
it was -80 then it became -44. The difference is 36.
Next we divide 36 by 9 from the 9 parents.
The answer is 4

All edge are 8 cm in length. What’s the surface area?
Answer:
192
Step-by-step explanation:
This is because its a square and all the sides on a square are equal so it would be:
top/bottom= 8*8
left/ right= 8*8
front/ back= 8*8
all equal 64 then you do 64*64*64 to get 192!

what is 100 + 84 – 62x = 494
Answer:
X= -5
Step-by-step explanation:
Good luck!
Answer:
X=-5
Step-by-step explanation:
100 + 84 - 62x =494
184 - 62x =494
494-184 = -62x
310 =-62x
310/-62 =x

If y varies directly with x, and y =9 when x=3, what is x when y=15
directly varies for that mean if y increases x will increase too and the other way around if y decreases x will decrease too.
an easy way to solve this is to make all values into fraction ik it sounds confusing lemme explain it. so if we say [tex]\frac{x}{y}[/tex] and add the values of the known [tex]\frac{3}{9}[/tex] we can say that if [tex]\frac{x}{15}[/tex] is equal to [tex]\frac{3}{9}[/tex]
now we just solve it for x
[tex]\frac{x}{15} = \frac{3}{9} \\9x = 45\\x= 5[/tex]
hence when y is 15 x will be 5

What is the value of x in the diagram?
A right angled triangle with base 2x+2, altitude x and hypotenuse 2x+3.
Answer:
x = 5
Step-by-step explanation:
x² + (2x+2)² = (2x+3)²
x² + 4x² + 8x + 4 = 4x² + 12x + 9
x² - 4x - 5 = 0
(x - 5)(x + 1) = 0
x = -1 This can be discounted as the answer because you cannot have a negative length
answer: x = 5

This formula is used to calculate the area of a circle using the diameter:
A= 1/4πd².
Rearrange the formula to calculate the diameter of a circle.
d = _____
Answer:
d= 2√a/π
To calculate the diameter, rewrite the formula to isolate D
Because a negative diameter doesn’t make sense, eliminate the negative answer from the solution
Simplify further to get the solution
The formula to calculate the diameter of the circle is d = 2 √( A/π )
where d = diameter of the circle
A = area of the circle
What is a Circle?
A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The perimeter of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle
Given data ,
Let the radius of the circle be = r
So , the diameter of the circle = 2r
Now , the area of the circle = πr²
Substituting the value for r , we get
Area of the circle = ( 1/4 ) πd²
So , A = ( 1/4 ) πd²
Now , solving the equation for diameter of circle d , we get
Multiply by 4 on both sides of the equation , we get
πd² = 4A
Divide by π on both sides of the equation , we get
d² = 4A/π
Taking square roots on both sides of the equation , we get
d = 2 √A/π
Therefore , the value of d is 2 √A/π
Hence ,
The formula to calculate the diameter of the circle is d = 2 √( A/π )
where d = diameter of the circle
A = area of the circle
