Answer: False.
Step-by-step explanation:
For any random variable x,
Formula to calculate the z-score : 
, where 
= Mean
= Standard deviation
Let x be the data point has a corresponding z-score of -1.5.
Then , we have
i.e. x is one and a half standard deviations below the mean value.
( one and a half =
)
Therefore , the given statement is false.
Answer:
She beat 6 levels last week

7 1/2 ÷ 1 1/4 = 6
1.) 18 in. by 1 in. 2.) 18 in. by 1 in. 3.) 2 in. by 9 in. 4.) 9 in. by 2 in. 5) 6 in.by 3 in. 6.) 3 in. by 6 in.
There are 6 shapes. I hope this helped.
Answer:
All angles must add up to 180, so if you add 69+5x+2+9y-3, it is = to 180.
First we can subtract 68 cancelling out 69, 2 and -3 so it is
5x+9y = 112. I assume this is an iscoceles triangle so we already knew 9y - 3 = 69, y=8, x=8
