What is 0.8637 rounded to the nearest hundredth​
umka21 [38]
<h3>Answer:</h3>

0.86

<h3>Step-by-step explanation:</h3>

The hundredths place is the second digit after the decimal point.  It is the 6 in this case.

Since the next digit (3) is 4 or less, the hundredths place stays the same and the rest is basically just cut off, leaving 0.86.

If the next digit (3) were 5 or more, the hundredths place would have gone up 1 (to 7) and the rest would have been cut off, giving a final result of 0.87

OFFERING 50 POINTS!!! The army reports that the distribution of waist sizes among female soldiers is approximately normal, with
hammer [34]

Answer:

Step-by-step explanation:

1)

Percentile is related to the area under the standard normal curve to the LEFT of a certain data value (which in this case would be 26.1 inches).

On my Texas Instruments TI-83 Plus calculator, I found this area as follows:

normcdf(-100, 26.1, 28.4,1.2), where the range -100 to 26.1 represents the area (as a decimal fraction) to the left of 26.1 inches.  My result was 0.028, which corresponds to the 3rd percentile (0.028 rounds off to 0.03, which would be 3rd percentile).

2)  The mean waist size is 28.4 inches, represented by a vertical line through the standard normal curve lying between 24 and 32.  We use the same function on the calculator:  normcdf(24, 32, 28.4, 1.2).

The result is 0.9985.  Subtracting this from 1.0000, we get 0.001, or 0.1%, which is the percentage of female soldiers requiring custom uniforms.

AysviL [449]

b) Cost of one gallon of gas is Toronto, Canada is higher by $ 1.17

Step-by-step explanation:

Complete Question

One gallon of gasoline in Buffalo, New York costs $2.29. In Toronto, Canada, one liter of gasoline costs  $0.91. There are 3.8 liters in one gallon.

a. How much does one gallon of gas cost in  Toronto? Round your answer to the nearest  cent.

b. Is the cost of gas greater in Buffalo or in  Toronto? How much greater?

Solution

Given

Cost of one gallon of gasoline in Buffalo, New York = 2.29 dollars

Cost of one liter of gasoline in Toronto, Canada = 0.91 dollars

One gallon = 3.8 liters

Thus, 1 liter = \frac{1}{3.8} gallons

a) Cost of \frac{1}{3.8} gallons of gasoline in Toronto, Canada = 0.91 dollars

Cost of 1gallons of gasoline in Toronto, Canada

=3.8 *  0.91\\= 3.458\\= 3.46

b) Difference in price for a gallon of gas for the two locations

3.46 - 2.29 \\= 1.17

Cost of one gallon of gas is Toronto, Canada is higher by $ 1.17
