Sally has a part time job mowing lawns so she can save money for a new car. She charges $5 per hour. What numbers make sense for

Ira Lisetskai [31]

Answer:

Independent: Amount of hours she works

Dependent: Amount of money she makes

Step-by-step explanation:

The independent variable is the part of the equation that changes. In this case the only thing that changes is how long she works, the amount of money she charges and what she is doing does not change.

The dependent variable is what you measure in the equation. In this case, the amount of money she makes depends on the amount of time she works.

Answer:

[ 0 ]

Step-by-step explanation:

The order of the matrix [ 3 1 1 ] is 1 by 3 and the order of the other matrix is 3 by 1 so this means that the order of the answer matrix is 1 by 1. So we multiply matrices row by columns.

[ 3 1 1 ] × | 2|

| -6|

| 0|

[ 3 × 2 + 1 × -6 + 1 × 0 ]

[ 6 - 6 + 0 ]

2. In an experiment with a mass attached to a spring, a student measures the period of the oscillation t as follows: 1.94 s, 1.9

Fed [463]

Answer: a) The average of this set of numbers is 1.98 s. b) the standard deviation is 0.02 s.

Step-by-step explanation: The average is calculated by adding all numbers found in the experiment divided by the number of values. $average = \frac{Sumxi}{n}$

The standard deviation is given by the square root of the squared sum of the difference between each number and the average divided by the total number of values. For instance, std deviation = $\frac{sqrt{(1.94-1.98)^{2}+(1.96-1.98)^2+(2.01-1.98)^2...}}{11}$ and that is done with all 11 terms of data minus the average to find the standard deviation.

In excel, the average of a certain set of numbers (displayed in cells A1 to A5) can be found by the commands =average(A1:A5). The standard deviation can be found by the commands =stdedv.p(A1:A5) in which p is the population. You can decrease decimals by clicking on the icon displayed in the Ribbon.

Jeremy is driving to a friend's house that is 72 miles away from his home. The scale on Jeremy's map is 1/2 inch is equivalent t

elena-s [515]

Answer:

Jeremy's house is 4.5 inches far from his friend's house on the map

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ The house of Jeremy's friend is 72 miles away from his home

∴ The actual distance between the two houses is 72 miles

∵ The scale on Jeremy's map is $\frac{1}{2}$ inch is equivalent to 8 miles

∴ Each $\frac{1}{2}$ miles on the map represents actual distance 8 miles

By using the ratio method

→ Map length : Actual length

→ inch : miles

→ $\frac{1}{2}$ : 8

→ x : 72

By using cross multiplication

∵ x × 8 = $\frac{1}{2}$ × 72

∴ 8 x = 36

- Divide both sides by 8

∴ x = 4.5

x represent the distance between the two houses on the map

Jeremy's house is 4.5 inches far from his friend's house on the map
