Answer:
C
Step-by-step explanation:
So this is transformations
So this seems like it was rotated 180 degrees then dilated by a scale factor
The rule for 180 degrees is (-x,-y)
The rule for dilations is (2x,2y)
So the answer should be
C. (-2x,-2y)
Have a nice day
Answer:
The minimum score is 28.
Step-by-step explanation:
(95+54+98+81+2x)/6>64
(328+2x)/6>64
328+2x>384
2x>384-328
2x>56
x>28
Answer:
1/36
Step-by-step explanation:
Since Tess rolled 2 different dices, there are 36 different possibilities. Rolling two 4's is 1 of them.
Therefore, the probability of Tess rolling 2 fair dice is 1/36
Hope this helped have a great rest of your day!
Answer:
Step-by-step explanation:
First you must find the number of cubic feet in the pool. (That's volume)
Formula
V = l*w*h
Givens
Solution
<em><u>Volume</u></em>
V = 38 * 22 * 8
V = 6688 cubic feet.
<em><u>Gallons</u></em>
1 cubic foot = 7.5 gallons
6688 ft^3 = x
<em><u>Proportion</u></em>
1/6688 = 7.5 / x Cross Multiply
x * 1 = 7.5 * 6688
x = 50160 gallons
Answer:
f(x) = 30 • 0.989x
Step-by-step explanation:
Given the data :
10 26.8
20 23.9
30 21.3
40 19
50 16.9
60 15.1
Using technology, the exponential model equation obtained by plotting the data is :
y = 30.068(0.989)^x
Based on the general exponential formula :
y = ab^x
y = predicted value
Initial value, a = 30.068
Rate = b = 0.989
The most appropriate model equation from the options given is :
f(x) = 30 • 0.989^x
