Often, frequency distributions are reported using unequal class widths because the frequencies of some groups would otherwise be small or very large. Consider the following data, which represent the daytime household temperature the thermostat is set to when someone is home for a random sample of households. Determine the class midpoint, if necessary, for each class and approximate the mean and standard deviation temperature.

The sample standard deviation is 13.22°F

Step-by-step explanation:

Given - Often, frequency distributions are reported using unequal

class widths because the frequencies of some groups would

otherwise be small or very large. Consider the following data,

which represent the daytime household temperature the

thermostat is set to when someone is home for a random sample

of households. Determine the class midpoint, if necessary, for

each class and approximate the mean and standard deviation

temperature.

Temp Frequency Class Midpoint

70 191 70.5

71-72 122 72

73-76 81 75

77-80 52 79

To find - The sample standard deviation is _____degrees°F.

Proof -

Temp Frequency(f) Midpoint(m) m×f ( m - 70.73 )²×f

61-64 34 63 2142 2031.6

65-67 68 66.5 4522 1216.7

71-72 122 72 8784 196.8

73-76 81 75 6075 2224.4

77-80 52 79 4108 3556.4

∑f = 744 ∑m×f = 52620.5 ∑ = 9822.6

So, Mean = [tex]\frac{52620.5}{744}[/tex] = 70.73

Sample standard deviation = [tex]\frac{9822.6}{744 - 1} = \frac{9822.6}{743}[/tex] = 13.22

∴ we get

The sample standard deviation is 13.22°F

If 42,800 dollars is invested at an interest rate of 5 percent per year, find the value of the investment at the
end of 5 years for the following compounding methods.

What is the
Annual $
Semiannual $
Monthly $
Daily $
Continuously $

Answers

Answer:

Annual $54,624.85

Semiannual $54,787.62

Monthly $54,927.75

Daily $54,955.35

Continuously $54,955.35

Step-by-step explanation:

If 42,800 dollars are invested at an interest rate of 5 percent per year, to find the value of the investment at the end of 5 years for the following compounding methods, the following calculations must be performed:

Annual $54,624.85

42,800 (1 + 0.05 / 1)^5x1 = X = 54,624.85

Semiannual $54,787.62

42,800 (1 + 0.05 / 2)^5x2 = X = 54,787.62

Monthly $54,927.75

42,800 (1 + 0.05 / 12)^5x12 = X = 54,927.75

Daily $54,955.35

42,800 (1 + 0.05 / 365)^5x365 = X = 54,955.35

Continuously $54,955.35

42,800 (1 + 0.05 / 365)^5x365 = X = 54,955.35

Step-by-step explanation:

(2, 6) is not a solution to the given system of linear equations.

y = 5x - 4 = 5*2 - 4 = 10 - 4 = 6

y = - 1/2x + 8 = - 1/2 * 2 + 8 = - 1 + 8 = 7

Since, point (2, 6) does not satisfy to equation 2.

Therefore, (2, 6) is not a solution to the given system of linear equations.

5th grade math/// In the first week of a food drive, the 5th grade collected 2 3/4 bags of canned goods. The goal is to collect 2 1/2 times as many bags in the second week. How many bags is the 5th grade hoping to collect in the second week?

Answers

The number of bags that would be collected in the second week is 6 7/8 bags.

How many bags would be collected in the second week?

A mixed number is a number that is made up of an integer and a proper fraction. A proper fraction is a fraction that has a numerator that is less than the denominator. An example of a mixed number is 2 3/4.

In order to determine the number of bags that would be collected in the second week, multiply 2 3/4 by 2 1/2. Multiplication is the mathematical operation that is used to determine the product of two or more numbers.

Number of bags collected in the second week = 2 3/4 x 2 1/2

11/4 x 5/2 = 55/8 = 6 7/8 bags
