Match the following words to the correct definition:
_____ translation ______ rotation ______reflection _____dilation
A. Flip B. Enlarge/reduce C. Turn D. Slide
Answer:
A. Flip ---> reflection
B. Enlarge/reduce ---> dilation
C. Turn ----> rotation
D. Slide ----> translation
Step-by-step explanation:
D and translation
A and reflection
C and rotation
B and dilation
it just makes sense.
dilation means like if you stung by a bee and it starts to swell but it can also be used as a way to say something shrunk.
reflection means yourself flipped
rotation means like your turning around or turning something around
i don't know if translation has anything to do with slide but it was the last option and all the others make sense.
Suppose that populations of men and women have the following summary statistics for their heights (in
centimeters):
Mean
Standard deviation
Men
HM = 172
M = 7.2
Women
Uw = 162
ow = 5.4
Both distributions are approximately normal. Suppose we randomly select a man and a woman from each
population, and calculate the difference between their heights. We can assume that their heights are
independent
Find the probability that the woman is taller than the man
You may round your answer to two decimal places

P woman taller
Answer:
.13
Step-by-step explanation:
172-162 = 10
We can find the standard deviation of D by adding the variances of the heights and taking the square root:

Representing probability with area
When D= M-W =0, their heights are equal. When the man is taller, D is positive, and when the woman is taller, D is negative. Since we know the distribution of the difference D is normally distributed, the probability that the woman is taller than the man can be found by calculating the shaded area below D=0, in the corresponding normal distribution:
A standard normal curve is plotted on a horizontal axis representing D, that goes from negative 17 to 37. The mean, or mu sub D, = 10. The standard deviations, or sigma sub D = 9. The value 0 is marked. The area under the curve to the left of 0 is shaded, representing the probability that the woman is taller. The area to the right represents the probability that the man is taller.
normalcdf:
lower bound: −9999
upper bound: 0
μ=10
σ=9
Using subtraction of normal variables, it is found that there is a 0.1335 = 13.35% probability that the woman is taller than the man.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X. When two measures are subtracted, the mean is the subtraction of the means while the standard deviation is the square root of the variances.In this problem:
Men have mean weight of 172 cm, women of 162 cm, hence, for the distribution of the differences, the mean is [tex]\mu = 162 - 172 = -10[/tex].The standard deviation is the square root of the sum of the variances, hence [tex]\sigma = \sqrt{7.2^2 + 5.4^2} = 9[/tex]The probability of the women being taller is P(X > 0), which is 1 subtracted by the p-value of Z when X = 0.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0 - (-10)}{9}[/tex]
[tex]Z = 1.11[/tex]
[tex]Z = 1.11[/tex] has a p-value of 0.8665.
1 - 0.8665 = 0.1335
0.1335 = 13.35% probability that the woman is taller than the man.

A rectangular water tank is 80 m long, 50 m wide and 60 m height. If the
depth of water in the tank is 45 m, find the volume of water required to
completely fill the tank?*
A)240,000cm3
B)60,000cm3
C)180,000cm3
D)120,000cm3
Answer: 2
Step-by-step explanation:
80 x 50 x 60 is volume of tank
240000
Water is already filled to 45 so volume up to that is
80x 50 x 45 = 180000
Subtract to find the difference needed to fill tank
240000 - 180000 = 60000
The volume of water to completely fill the tank is A) 240,000cm³.
What is volume?Volume is defined as the amount of three-dimensional space occupied by some close object.
We know the volume of a cuboid is (Height×Width×Length).
Given a rectangular water tank is 80m long, 50m wide and 60m in height and the depth of the water is 45m.
To obtain the volume of water we have to take 45m as the height or we can think of the height of the tank is 60m but water can only be filled up to 45m.
∴ The volume of the water is (80×50×45) m³.
= 180,000 m³.

The equation m=40g gives the distance in miles, m, that a car can travel using g gallons of gas
a. If the car has gone 140 miles, how much gas was used
B. Write an equation the represents the inverse function
Answer:
3.5 gallons
Step-by-step explanation:
140=40g
140/40=g
a) The car used 3.5 gallons of gas
b) The inverse function is g=m/40
What is an inverse function?In mathematics, an inverse is a function that serves to “undo” another function. That is, if f(x) produces y, then putting y into the inverse of f(x) produces the output. A function that has an inverse is called invertible and the inverse is denoted by f⁻¹
Given here, distance = 140 and equation m=40g then using the equation we get
140 = 40 ×g
g= 3.5 gallons
and the inverse function is given by g = m/40
Hence the car uses 3.5 gallons and we found the inverse function is g=40/m

A sphere is a three-dimensional geometric figure, hollow or solid, contained by a continuously round surface that is equidistant from its center. The maximum capacity of a sphere is calculated with the formula, where V = volume, and r = radius. For a sphere with a maximum capacity of 1,372pi/3 cubic millimeters, the diameter measures millimeters.
Answer:
14 millimeters
Step-by-step explanation:
V=(4/3)πr³
1372π(1/3)=(4/3)πr³
1372=4r³ (cancel out the pi and multiply both sides by 3)
r³=343
r=7
Diameter is twice the radius = 2(7) = 14

The average rate of change of h(t) = -16t ² + 40t + 4 between t = 0 and t = 2 is
(h (2) - h (0)) / (2 - 0) = ((-16×2² + 40×2 + 4) - (-16×0² + 40×0 + 4)) / 2
… = ((-64 + 80 + 4) - 4) / 2
… = 16 / 2
… = 8
h(t) is measured in feet, so the average rate of change is measured in feet per second, so it's 8 feet per second.

The equation for line g can be written as y = x + 5. Parallel to line g is line h, which passes through the point (-6, -4). What is the equation of line h? SHOW WORK PLEASE
Answer:
y=x+2
Step-by-step explanation:
we know the slopes have to be equal because the lines are parallel, so the slope is 1, or written as x. plug the point given, (-6,-4), and the slope, 1, into the y=mx+b equation to find the y-intercept. then solve. then put the slope and y-intercept together for the equation of line h.
y=mx+b, m=1, x=-6, y=-4
-4=(1)(-6)+b
-4=-6+b
2=b
y=x+2
