Answer:
A standard normal distribution refers to a normal distribution with a mean of 0 and a standard deviation of 1. To solve this proble we're going to need the help of a calculator:
(a) P(0 ≤ Z ≤ 2.38) = 0.4913
(b) P(0 ≤ Z ≤ 1) = 0.3413
(c) P(−2.70 ≤ Z ≤ 0) = 0.4965
(d) P(−2.70 ≤ Z ≤ 2.70) = 0.9931
(e) P(Z ≤ 1.62) = 0.9474
(f) P(−1.55 ≤ Z)= 0.9394
(g) P(−1.70 ≤ Z ≤ 2.00) = 0.9327
(h) P(1.62 ≤ Z ≤ 2.50) = 0.0464
(i) P(1.70 ≤ Z) = 0.0445
(j) P(|Z| ≤ 2.50) = 0.9876
All values are verified! ✅
Answer:
<u>100 degrees</u>
Step-by-step explanation:
y = ½ (b + x)
80 = 1/2(60 + x)
80 = 30 + x/2
50 = x/2
x/2 = 50
x = 100
<u>This means that the value of x in this picture is 100 degrees</u>
Answer:
1 21/250
Step-by-step explanation:
1 5/12 in decimal form is 1.416 so you take 2 1/2 bags of apples and make it a decimal, is 2.5 so you subtract them and get 1.084 and that in its most simplified feaction is 271/250 and in standard form is 1 21/250 in simplified form so that is how many bags of apple he will have left. Hope this helps!
