Answer:
Step-by-step explanation:
find the attachment showing std normal curve symmetrical about y axis.
Equal probabilities on either side of the mean thus the total probability to the right of mean is 0.50
From the table we can find that
a) P(Z>2.5) = 0.5- area lying between 0 and 2.5
= 0.5-0.4938 =0.0062
b) P(1.2<z<2.2) = F(2.2)-F(1.2)
= 0.9861-0.3849
=0.6012
Answer:
The weight of 12 tennis balls = 691. 2 grams
Step-by-step explanation:
The weight of each tennis ball = 57.6 grams
So, the weight of 12 balls = 12 x ( weight of 1 ball)
= 12 x 57.6 grams
= 691.2 grams
⇒12 balls weigh 691.2 grams
Hence, the weight of 12 tennis balls = 691. 2 grams

Answer:
6.3 units (nearest tenth)
Step-by-step explanation:

Using the formula above,
distance between (-8, 6) and (-6, 0)
![= \sqrt{ {[ - 8 - ( - 6)]}^{2} + {(6 - 0)}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%20%7B%5B%20-%208%20-%20%28%20-%206%29%5D%7D%5E%7B2%7D%20%20%2B%20%20%7B%286%20-%200%29%7D%5E%7B2%7D%20%7D%20)




= 6.3 units (nearest tenth)
I’m sorry but how r we supposed to answer there’s no picture
