Answer:
The right answer is:
"If 74% of Americans still favor mandatory testing this year, then there is a 1.5% chance that poll results will show 71% or fewer with this opinion."
Step-by-step explanation:
The P-value represents the probability of getting the sample we got, given that the null hypothesis is true. For this reason, it the P-value is lower than the significance level, it means that the sample result is unlikely due to chance, but due to a false null hypothesis.
In this case, the P-value represents a probability P=0.015 of having a sample with proportion p=0.71, given that the population has a proportion π=0.74.
The right answer is:
"If 74% of Americans still favor mandatory testing this year, then there is a 1.5% chance that poll results will show 71% or fewer with this opinion."
Answer:
The small tire would make about 127 rotations.
The large tire would make about 38 rotations.
b. Would you rather ride a bicycle made with two large wheels or two small wheels? Explain.
Two large wheels. Because the larger wheel makes a smoother ride and you spend less energy in order to move, compared to smaller wheels. Also, the larger the diameter, the further it can travel over one revolution.
A bicycle with would allow you to travel farther with each rotation of the pedal.
The larger one. Because in one rotation the larger wheel moves 188.49 inches and the smaller one 56.55 inches.
Step-by-step explanation:
- Big wheel 60 inches
- Small wheel 18 inches.
a. How many rotations does each tire make after traveling 600 feet? Round your answers to the nearest whole number.
Considering: 
Large tire:
Small tire:
You can draw a right triangle with the informatio.
The vertical change in elevation (unknown) is the opposed leg to the angle 15°
The distance from the surveyor to the point vertically below the point on the mountain is the adjacent leg = 6 miles.
Then tan(15°) = x / 6 => x = 6tan(15) = 1.61 miles
Answer: 1.61 miles
Answer:
(x,y)=(6,6)

Answer:
r = 64
Step-by-step explanation:
r = (k*t*u)/s
Where,
k = constant of proportionality
t = -12,
u= -7,
s= -4,
r= -126.
r = (k*t*u)/s
-126 = (k*-12*-7)/-4
-126 * -4 = 84k
504 = 84k
k = 504/84
k = 6
Find r when t= -8, u= 8, and s= -6.
r = (k*t*u)/s
= (6*-8*8) / -6
= -384 / -6
= 64
r = 64
