Answer:
0.7102
0.8943
0.3696
Step - by - Step Explanation :
A.) Between $1320 and $970
P(Z < 1300) - P(Z < 970)
find the Zscore of each scores and their corresponding probability uinag the standard distribution table :
P(Z < (x - μ) /σ) - P(Z < (x - μ) / σ))
P(Z < (1320 - 1250) /120) - P(Z < (970 - 1250) / 120))
P(Z < 0.5833) - P(Z < - 2.333)
0.7200 - 0.0098 = 0.7102 (Standard
=0.7102
B.)Under 1400
x = 1400
P(Z < 400)
P(Z < (x - μ) /σ)
P(Z < (1400 - 1250) /120)
P(Z < 1.25) = 0.8943
C.) Over 1290
P(Z > 1290)
P(Z < (x - μ) /σ)
P(Z > (1290 - 1250) /120 = 0.3333
P(Z > z) = 1 - P(Z < 0.3333) = P(Z < 0.3333) = 0.6304
P(Z > 0.3333) = 1 - 0.6304 = 0.3696
Answer:
28°
Step-by-step explanation:
1. We can see that ∠GFH has two smaller angles within it: ∠1 and ∠2. Given that m∠GFH is 53° (the whole thing), and m∠2 is 25° (a part of it), we just have to subtract 25 from 53 to get the measure of ∠1.
Therefore, m∠1 = 28°.
Answer:
10 cm
Step-by-step explanation:
Because it is a parrallogram and by its property it will be 10
STEP 1
calculate total ounces
= 16 oz/lb * 3 lbs
= 48 ounces
STEP 2
calculate number of bolts; divide total weight (48 ounces) by ounces per bolt
x= number of bolts purchased
x= 48 ounces ÷ 1/15 oz per bolt
x= 48 ÷ 1/15
to divide by fraction; multiply by reciprocal of 1/15
x= 48 * 15/1
x= 720 bolts
ANSWER: He purchased 720 bolts
