The answer is B i took the practice test and got it right :)
6 apples + 4 peaches = 10 pieces of fruit
First choice is an apple = 6 /10 = 3/5
Now, there are:
5 apples + 4 peaches = 9 pieces of fruit
Second choice is a peach = 4 /9
Multiply the 2 fractions:
3/5 x 4/9 = 12/45 = 4/15
Answer= 4/15 (A)
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
