Answer:
0.8808
Step-by-step explanation:
The objective is to calculate the probability of:
P(-1.20 ≤ z ≤ 2.64)
i.e. the probability that is the area between two z-values.
Thus;
P(-1.20 ≤ z ≤ 2.64) = P(z ≤ 2.64) - P( z ≤ 1.20)
From z table;
P(-1.20 ≤ z ≤ 2.64) = 0.9959 - 0.1151
P(-1.20 ≤ z ≤ 2.64) = 0.8808
We can see the shaded area under the standard normal curve from the image attached below.
Answer:
4.24
Step-by-step explanation:
Answer: In my opinion you could just shorten the number of orders so that it's not so long.
Explanation: The numbers can be from every 20 orders so 900, 920, 940...so on.
Answer:
BC = 3.6
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
1.5 BC = 5.4 ( divide both sides by 1.5 )
BC = 3.6
Answer:
The multiplication of 3
Step-by-step explanation:
when you see the 3(6y+1), it basically means multiply the 3 with the 6y and the 1. Therefore, it would be 18y+3
