Answer:
But Mars has no magnetosphere, and its atmosphere is over 100 times thinner than Earth's atmosphere. The trip to Mars and the stay on Mars will mean extended radiation exposure. Astronauts will need special habitats, suits, and machines that will protect them from radiation, which otherwise could cause cancer.

Joey ate brunch at a restaurant. The bill came to $39. If he left a 15% tip, how much was the tip?
Answer:
The tip that Joey left was $ 5.85.
Step-by-step explanation:
Given that Joey ate brunch at a restaurant, and the bill came to $ 39, to determine, if he left a 15% tip, how much was the value of it, the following calculation should be performed:
39 x 15/100 = X
585/100 = X
5.85 = X
So, the tip that Joey left was $ 5.85.

Answer: 11.76
Step-by-step explanation:
The formula for cylinder is pi*r^2*h
so substitute and you will get pi*1.44*2.6
Simplify it and you will get 11.75616 or 11.76.

At a snack bar, each medium drink costs $1.85 and each large drink cost c more dollars than a medium drink. If 5 medium drinks and 5 large drinks cost a total of $20.50, what is the value of c?
A) 0.45
B) 0.40
C) 0.30
D) 0.25
Answer:
B) 0.40
Step-by-step explanation:
m = 1.85
l = 1.85 + c
With 5 medium drinks and 5 large drinks:
C = 5m + 5l
20.5 = 5(1.85) + 5(1.85 + c)
20.5 = 9.25 + 9.25 + 5c
20.5 = 18.5 + 5c
5c = 20.5 - 18.5
5c = 2
c = 2/5 = 0.4
You have collected data on the average weekly amount of studying time (T) and grades (G) from peers at your university. Changing the measurement from minutes into hours has the following effect on the correlation coefficient:
a. cannot be computed since some students study less than an hour per week
b. does not change the rTG
c. decreases the rTG by dividing the original correlation coefficient by 60
d. results in a higher rTG
Answer:
b. does not change the rTG
Step-by-step explanation:
If the average weekly amount of studying time and Grade are compared such that a certain correlation Coefficient value is obtained, changing the unit of measurement of any of the variables, will not affect the value of the correlation Coefficient most notably because the value of R, correlation Coefficient is a normalized or standardized value that ranges between - 1 and 1 and hence, resistant to unit changes in the compared variables. Hence, Correlation coeffient for the rate of study and grade obtained will not change even if rate of study is measured in hour.
Answer:
b. does not change the rTG

Which line has the same slope as the lone passing through (-4,-1) and (-1,-7)
1) 6x+3y=5
2)y=-1/2x-7
3)y=-2
Answer:
1) 6x+3y=5
Step-by-step explanation:
1) First, find the slope of the line passing through (-4, -1) and (-1, -7). Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the two points into the formula and solve:
[tex]m = \frac{(-7)-(-1)}{(-1)-(-4)} \\m = \frac{-7+1}{-1+4} \\m = \frac{-6}{3} \\m = -2[/tex]
So, the slope is -2.
2) Now, identify the slopes of the lines in the options. We already know the slope of [tex]y = -\frac{1}{2} x-7[/tex] is [tex]-\frac{1}{2}[/tex] since it is in slope-intercept form. y = -2 must have a slope of 0 since it's horizontal, and all equations with the format of y = a number are horizontal.
To find the slope of [tex]6x + 3y = 5[/tex], isolate y to put the equations into slope-intercept form ([tex]y = mx + b[/tex] format), and whatever the coefficient of the x-term is will be the slope.
[tex]6x + 3y = 5\\3y = -6x+5\\y = -2x + \frac{5}{3}[/tex].
So, the slope of the first option is -2. It matches the slope we calculated in the first step, so that must be the answer.

Becuase all circles are similar.
Noboday talks about the circle due to all circle are similar.
We have find the rotation of coordinate plane also we have talk about the coordinate plane in circle.
What is the rotations on the coordinate plane?
Rotations coordinate plane may be clockwise or counterclockwise.
When we are working in the coordinate plane assume the center of rotation to be the origin unless told otherwise.

D. Divide 132 by 217
Answer:
B
Step-by-step explanation:
i did the math
The joint relative frequency of being a child who prefers watermelon is 132/445 option (A) Divide 132 by 445 is correct.
What is a conditional relative frequency?It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the frequency cell by the total frequency.
To find the joint relative frequency of being a child who prefers watermelon:
Total number of children who prefers watermelon = 132
Total number of children and adults = 445
joint relative frequency of being a child who prefers watermelon:
= 132/445
Thus, the joint relative frequency of being a child who prefers watermelon is 132/445 option (A) Divide 132 by 445 is correct.

HOW DO WE FIND THE PRODUCT OF A FRACTION
Answer:
you have to multiply the given fractions because product means Times
Step-by-step explanation:
In order to find the product of a fraction
you just have to multiply both numerator and denominator, then we reduce it (if needed).

Ethan buys a bag of cookies that contains 8 chocolate chip cookies, 7 peanut butter cookies, 7 sugar
cookies, and 7 oatmeal cookies.
What is the probability that Ethan feaches in the bag and randomly selects an oatmeal cookie from the
bag, eats it, then reaches back in the bag and randomly selects a peanut butter cookie? Round your answer
to four decimal places.
Answer:
0.0603
Step-by-step explanation:
probabilty ethan picks an oatmeal and peanut butter cookie = probability of selecting an oatmeal cookie x probability of selecting a peanut butter cookie
probability of selecting an oatmeal cookie = number of oatmeal cookies / total number of cookies
probability of selecting a peanut butter cookie = number of peanut butter cookies / total number of cookies
total number of cookies = 7 + 7 + 7 + 8 = 29
probability of selecting an oatmeal cookie = 7/29
probability of selecting a peanut butter cookie = 7/28
after eating oatmeal cookies, the amount of cookies would reduce by 1
