Answer:
C
Step-by-step explanation:
There is a positive correlation, as hours spent gets bigger the test score gets bigger with some outliers
<span>The mean of a set of data is 148.87 and its standard deviation is 68.29. Find the z score for a value of 490.19
the z-score is given by:
z=(x-</span>μ<span>)/</span>σ
plugging in the values in the expression we get:
z=(490.19-149.87)/68.29
z=340.32/68.29
z=4.9835
Hi
The answer is 2.6
I'm sorry if it's incorrect
10:6...added = 16
adding 112
10/16(112) = 1120/16 = 70
6/16(112) = 672/16 = 42
he should add 70 white golf balls and 42 striped gold balls
