To solve this problem we use the z statistic. The formula
for z score is:
z = (x – u) / s
where,
x = sample value mean = 178 – 0.56 = 177.44 mm
u = total sample mean = 178 mm
s = standard deviation = 12 mm
z = (177.44 – 178) / 12
z = -0.05
from the tables P (z = -0.05) = 0.484
So the probability P is: [multiply by 2 since we account the two sides)
<span>P = (0.5 – 0.484) * 2 = 0.0320</span>
Answer: $4.45
Step-by-step explanation: you will get $4.45
Answer:
x=-7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x−(15x−6)=104
x+−1(15x−6)=104(Distribute the Negative Sign)
x+−1(15x)+(−1)(−6)=104
x+−15x+6=104
(x+−15x)+(6)=104(Combine Like Terms)
−14x+6=104
−14x+6=104
Step 2: Subtract 6 from both sides.
−14x+6−6=104−6
−14x=98
Step 3: Divide both sides by -14.
−14x/-14 = 98/-14
<u>x=-7</u>
Hope this helps!
8 x 8= 64 so 8 is your answer.
Given:
1/6 of a crate of potatoes every
1/18 of an hour
We get the unit rate by dividing the ratio of the crate by the ratio of the hour.
1/6 ÷ 1/18 ⇒ 1/6 * 18/1 = 18/6 = 3 per hour
The unit rate is 3 per hour.
