Answer:
0.6710
Step-by-step explanation:
The diameters of ball bearings are distributed normally. The mean diameter is 107 millimeters and the population standard deviation is 5 millimeters.
Find the probability that the diameter of a selected bearing is between 104 and 115 millimeters. Round your answer to four decimal places.
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 107 mm
σ is the population standard deviation = 5 mm
For x = 104 mm
z = 104 - 107/5
z = -0.6
Probability value from Z-Table:
P(x = 104) = 0.27425
For x = 115 mm
z = 115 - 107/5
z = 1.6
Probability value from Z-Table:
P(x = 115) = 0.9452
The probability that the diameter of a selected bearing is between 104 and 115 millimeters is calculated as:
P(x = 115) - P(x = 104)
0.9452 - 0.27425
= 0.67095
Approximately = 0.6710

What are the square roots of each perimeter of a rectangle?
Answer:
Step-by-step explanation:
The perimeter is simply 2 times length + 2 times width. In the case of our square, this would simply be 2x+2x (since length = width), or 4x . Therefore, if given an area, all you'd do is take the square root (to get from x2 to x , and then multiply by 4 to find perimeter.
Answer:
The first method
Take a square root, then multiply it by 4.
The defining characteristic of a square is that its length is equal to its width. Take a look below:
Self-created
So, for this particular square, the area is length⋅width, or x⋅x=x2. Now, how can you go from this to perimeter?
Well, the formula for perimeter is simply 2 times length + 2 times width. In the case of our square, this would simply be 2x+2x (since length = width), or 4x.
Therefore, if given an area, all you'd do is take the square root (to get from x2 to x, and then multiply by 4 to find perimeter.
The second method
s=√A
P=4×s
Explanation:
To find the perimeter of square, you just need to know the length of one side, because in a square all the sides are the same length.
If you know the area, find the square root of it to find the side.
s2=A
∴s=√A
Now you multiply by 4
For example, if the area is 36cm2
A=36
s=√36=6
P=4×6=24

Jerry rhombus has a base of 15 inches and a height of 9 inches. Charlene rhombus has a base
Complete Question:
Jerry’s rhombus has a base of 15 inches and a height of 9 inches. Charlene’s rhombus has a base and a height that are 13 the base and height of Jerry’s rhombus. Compare the area of Charlene’s rhombus to the area of Jerry’s rhombus.
Answer:
Charlene's rhombus has a larger area
Step-by-step explanation:
Given
Jerry's
[tex]Base = 15in[/tex]
[tex]Height = 9in[/tex]
Charlene's
[tex]Base = Height = 13in[/tex]
Required
Compare both areas
The area of rhombus is:
[tex]Area = Base * Height[/tex]
For Jerry's
[tex]Area = 15in * 9in[/tex]
[tex]Area = 135in^2[/tex]
Charlene's
[tex]Area = 13in * 13in[/tex]
[tex]Area = 169in^2[/tex]
By comparison: Charlene's rhombus has a larger area by 34in^2

Lucas scored 9 goals in 4 soccer games last season. Approximately how many points did Lucas average per game?
Answer:
Lucas scored approximately 2.25 or 2 1/4 goals per game.
Step-by-step explanation:
To find out just divide 9 to 4. Hope this helps :)
Lucas scored points at an average 2.25 per game.
What is average?The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the sum of the total number of observations by the total number of observations.
Given:
Lucas scored 9 goals in 4 soccer games last season.
Average per game = total goals / total game.
= 9/4
= 2.25
Therefore, the average is 2.25 per game.

The McDonald's Play Place is going to increase its ball pit size to allow for more fun! The ball pit was originally 10 feet by 12 feet. They have decided to increase each side by the same amount. Express the area of the new pit as a polynomial in simplest form.
Answer:
A = x² + 22x + 120
Step-by-step explanation:
Since the ball pit was originally 10 feet by 12 feet and each side is increased by the same amount which we would call x, the new length of sides are thus 10 + x and 12 + x respectively.
The area of the new pit is thus A = (10 + x)(12 + x), since it is a rectangle.
Expanding the brackets, we have
A = 10 × 12 + 10x + 12x + x²
collecting like terms, we have
A = 120 + 22x + x²
A = x² + 22x + 120
Find the value of x.

your gym membership cost $33 per month after an initial membership fee. you paid a total of $228 after 6 months. writer an equation that gives the cost as a function of the length of your gym membership (in months). find the total cost after 9 months
Answer:
what i did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a 9-month total cost of $327
Step-by-step explanation:
cost = $33 per month + fee
1. c(m) = 33m + f
33(6) + f = 228
198 + f = 228
f = $30 membership fee
c(m) = 33m + 30
2. at 9 months: 33(9) + 30 = $327
hopefully this helps :)

At 100°F, a certain Insect chirps at a rate of 97 times per minute, and at 102°F, they chirp 111 times per minute. Write an equation in slope-intercept form that represents the situation.
Answer:
y = 7x - 603
Step-by-step explanation:
We start by determining the slope:
m = y2 - y1/x2 - x1 = 111 - 97/102 - 100 = 14/2 = 7,
Now we substitute the slope into the slope-intercept equation y = mx + b, solving for the y-intercept [b]:
111 = 7(102) + b,
b = -603
Equation: y = 7x - 603

this is standard form (9x10 to the power of -4) to the power of 2
Answer:
9×10 to the power of -8
Step-by-step explanation:
Cause when we add power to the power we multiply them
For example [tex](2^{2} )^2[/tex] , we multiply the power so , 2×2= 4 so [tex](2^{2} )^2[/tex] = [tex]2^{4}[/tex]=16
Same here [tex]((9*10)^{-4} )^2[/tex] we multiply the powers so -4×2=-8
So [tex]((9*10)^{-4} )^2[/tex] =[tex](9*10)^{-8}[/tex] = 2.323×[tex]10^{-16}[/tex]
