Answer:
0.82%
Step-by-step explanation:
First find the z-score.
z = (x − μ) / σ
z = (72 − 60) / 5
z = 2.4
Use a chart or calculator to find the probability.
P(Z > 2.4) = 1 − P(Z < 2.4)
P(Z > 2.4) = 1 − 0.9918
P(Z > 2.4) = 0.0082
Answer: $36.8625
Step-by-step explanation:
From the question, we are informed that Brenda went to Fiesta Mart and bought 1 ¼ pounds of deli meat at $7 a pound and 9 ¾ pounds of rice at $0.45 per pound. The total amount that we spent will be:
= ($7 × 1.25) + ($0.45 × 9.75)
= $8.75 + $4.3875
= $13.1375
If Brenda paid for her purchase with a $50 bill, the change that she will receive will be:
= $50 - $13.1375
= $36.8625

On the left side, use the measure of each angle.
On the right side, use 180 because the the sum of the measures of the angles of any triangle is always 180.
90 + 45 + <X = 180
135 + <X = 180
<X = 180 - 135
<X = 45

90 + 56 + <H = 180
146 + <H = 180
<H = 180 - 146
<H = 34

A right triangle has 1 right angle measuring 90 degrees and two acute angles.
The sum of the measures of the three angles of a triangle is 180.
If you subtract 90 degrees (the right angle's measure) from the total of 180 degrees, 180 - 90 = 90, you get 90 degrees. That means that the sum of the measures of the two acute angles of a right triangle is always 90 degrees.
