Meteorologists in Florida claim a 2.3% margin or error when predicting the temperature more than 3 days out, while Ohio meteorologists allow for a 13.5% error in their calculations. If meteorologists in both states are predicting a 68° day in 5 days, what is the range of possible temperatures in Florida and Ohio. Select all that apply.
A) Florida: 1.564° margin of error; 66.4° - 69.6° range
B) Florida: 65.7° - 70.3° range.
C) Ohio: 9.18° margin of error; 58.8° - 77.2° range
D) Ohio: 54.5°- 81.5° range
A ,C,D
100* 2/7 = 28.6 %
What on earth did you do?
(.1812/12) * 529.84 = $12
It is 18.12 PER YEAR
divide by 12 for month
.023*68 = 1.564 yes + 68 = 69.6 ok agree A
.135 * 68 = 8.97 NOT 9.18 disagree on C
8.97+68 = 76.97 NOT 81.5 disagree on D
To find the percent of Silas's slime that is detergent, we need to calculate the ratio of detergent to the total amount of slime.
First, we need to add the amounts of glue and detergent together: 5 ounces + 2 ounces = 7 ounces.
Then, we find the percent of detergent by dividing the amount of detergent by the total amount of slime and multiplying by 100.
(2 ounces / 7 ounces) * 100 = 28.6%
So, the correct answer is D: 28.6%.
To calculate the amount of interest that Jose will pay in the first month, we need to use the formula:
Interest = (Interest Rate / 100) * Balance
Given that the interest rate is 18.12% and the balance is $529.84, we can calculate the interest payment:
(18.12 / 100) * 529.84 = $95.93
Rounded to the nearest cent, the interest payment in the first month is $96.00.
So, the answer is $96.00.
To find the range of possible temperatures in Florida and Ohio, we need to consider the margin of error for each state's meteorologists.
For Florida, with a margin of error of 2.3%, we calculate the range by subtracting and adding the margin of error to the predicted temperature:
Minimum temperature in Florida = 68° - (2.3/100) * 68° = 68° - 1.564° = 66.4°
Maximum temperature in Florida = 68° + (2.3/100) * 68° = 68° + 1.564° = 69.6°
For Ohio, with a margin of error of 13.5%, we perform the same calculation:
Minimum temperature in Ohio = 68° - (13.5/100) * 68° = 68° - 9.18° = 58.8°
Maximum temperature in Ohio = 68° + (13.5/100) * 68° = 68° + 9.18° = 77.2°
Thus, the correct options are A, C, and D.
