Answer:
0.68268
Step-by-step explanation:
We solve using z score
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
For x = 85
z = 85 - 105/20
z = -1
Probability value from Z-Table:
P(x = 85) = 0.15866
For x = 125
z = 125 - 105/20
z = 1
Probabilty value from Z-Table:
P(x = 125) = 0.84134
The probability that a randomly selected adult has an IQ between 85 and 125 is calculated as:
P(x = 125) - P(x = 85)
= 0.84134 - 0.15866
= 0.68268
Answer:
Two angles are supplementary if the sum of their measures is 180 . ... You can write "the measure of angle 1" as m∠1. ... Find m∠2, m∠3, and m∠4.
Step-by-step explanation:
$210
because if it rose 30%, it's now 130% of what is used to be
or (what it used to be) ×1.3
so do the reverse and divide the new cost by 1.3
so 273÷1.3 which is 210
Answer:
These should be right hopefully! Hope it helps!
Answer:
95°
Step-by-step explanation:
The angle on the 20TH street and 22ND street must add up to 180° so the answer is 95°
