Answer:
B. 30
Step-by-step explanation:
Boys to girls
2 : 3
Units of girls = 3
3 units = 18
1 unit = 18 ÷ 3 = 6
Total number of units = 2 + 3 = 5

Answer:
t = 2.64 or
Step-by-step explanation:
v(t) =
v(t) = -32t + C
when t = 0, the velocity is 12
12 = -32(0) + C
C = 12
v(t) = -32t + 12
now finding position
when t = 0, position is 80
80 = 0 + C, C = 80
now finding when position = 0
0 =
0 =
t = -1.89, 2.64
t>0, so t = 2.64
we know that
<u>The correlation coefficient </u>is a number between and that represent the linear dependence of two variables or sets of data
Let
Using the function CORREL in a Excel tool
Find the correlation coefficient for the set of data
see the attached table
the correlation coefficient is
therefore
<u>the answer is the option B</u>
