The answer is 12.21 you find this by dividing 149 by ten and then 11 then 12 next 13 then realize you went too far and its some where around 12. somthing. I know that was confusing but thats the only way i can explain it or just put this into a calculator:
4 more than a number = x + 4
is more than = >
thirteen = 13
x + 4 > 13
Answer: (A) 6.6 sec (B) 6.89 sec
<u>Step-by-step explanation:</u>
y = -16t² + 1700
1000 = -16t² + 1700
<u>-1700</u> <u> -1700 </u>
-700 = -16t²
<u> ÷-16 </u> <u>÷-16 </u>
43.75 = t²
√43.75 = √t²
6.6 = t
***********************************
y = -16t² + 1700
940 = -16t² + 1700
<u>-1700</u> <u> -1700 </u>
-760 = -16t²
<u> ÷-16 </u> <u>÷-16 </u>
47.5 = t²
√47.5 = √t²
6.89 = t
Answer:
A. 0.0625
B. 0.1089
C. 0.81
D. 0.0196
Step-by-step explanation:
The proportion of variance is shared by the two correlated variables is given as the r².
Therefore,
For A. r = 0.25
Proportion of variance is shared by the two correlated variables = 0.25²
= 0.0625
For B. r = 0.33
Proportion of variance is shared by the two correlated variables = 0.33²
= 0.1089
For C. r = 0.90
Proportion of variance is shared by the two correlated variables = 0.90²
= 0.81
For D. r = 0.14
Proportion of variance is shared by the two correlated variables = 0.14²
= 0.0196
