The answer is most likely B. :)
About 68% of the people will score between 85 and 115.
The values of 85 and 115 are exactly 15 points away, or 1 standard deviation, away from the mean.
According to the empirical rule, about 68% of the values in a normal distribution are within 1 standard deviation of the mean.
Answer:
135 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h(a + b)
where h is the height and a, b the parallel bases
Here h = 9, a = 13 and b = 17 , thus
A =
× 9 × (13 + 17)
= 0.5 × 9 × 30
= 135 cm²
Y+y-3 is the expression need to find the triangle's area
From the calculation done below, it can be seen that the cost of one orange is 85 cents.
<h3>How do we determine the cost of a product?</h3>
The cost of one orange can be determined as follows:
One dime = 10 cents
2 dollars = 200 cents
Total amount given by Sue to the store clerk = One dime + 2 dollars = 10 cents + 200 cents = 210 cents
Cost of two oranges = Total amount given by Sue to the store clerk –
Change = 210 cents – 40 cents = 170 cents
Cost of one orange = Cost of two oranges / 2 = 170 cents / 2 = 85 cents
