Answer:
0.81859
Step-by-step explanation:
We solve using z score method
The formula for calculating a z-score is is z = (x-μ)/σ,
where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Mean 0.8 pound
Standard deviation 0.25 pound
For x = 0.55 pound
z = 0.55 - 0.8/0.25
= -1
Probability -value from Z-Table:
P(x = 0.55) = 0.15866
For x = 1.3 pounds
Z = 1.3 = 0.8/0.25
= 2
Probability value from Z-Table:
P(x = 1.3) = 0.97725
The probability that a randomly selected zucchini will weigh between 0.55 pound and 1.3 pounds is
P(x = 1.3) - P(x = 0.8)
0.97725 - 0.15866
0.81859.
The correct answer is D. Why?
In that phase of solving he can not know that integers on each side will be equal or not.
Good luck!!!
If there is 10% of $18 = 18 x 0.9 (1 - 0.1) = $16.20
Therefore the pie costs $16.20
He is saving 18 - 16.20 = $1.80

Answer:
12
96
9
38
25
Step-by-step explanation:
<h3>i.a+7 for a=5</h3>
5+7=12
<h3>ii.8(c+3) for c =9</h3>
8(9+3)
8(12)
96
<h3>iii.n+8 divided by 4 for n=28</h3>
=28+8 divided by 4
=36 divided by 4
=9
<h3>iv.6p+40 divided by 5 for p =5</h3>
=6×5+40 divided by 5
=30+40 divided by 5
=70 divided by 5
=38
<h3>v.3x+7 for x=6</h3>
=3×6+7
=18+7
=25
