Answer:

\boxed {\boxed {\sf m= \frac{7}{2} \ or \ 3.5 }}

Step-by-step explanation:

The slope formula is the change in y over the change in x.

m=\frac{y_2-y_1}{x_2-x_1}

In this formula, (x₁, y₁) and (x₂, y₂) are the points given. We are given the points (5, -3) and (7,4). Therefore,

x_1=5 \\y_1= -3\\x_2=7 \\y_2=4

Substitute the values into the formula.

m=\frac{4--3}{7-5}

Solve the numerator.

  • 4 - -3 = 4+3 = 7

m=\frac{7}{7-5}

Solve the denominator

  • 7-5=2

m=\frac{7}{2}

m=3.5

The slope between the points is 7/2 or 3.5

Answer: slope is \frac{7}{2} or 3.5

Step-by-step explanation:

Slope =  \frac{y_2-y_1}{x_2-x_1} = \frac{4-(-3)}{7-5} = \frac{7}{2}

If 1 ft = 1.894 x 10​ -4​miles, convert 20.0 inches to miles
Yakvenalex [24]

Answer:

3.1567 * 10^-4 miles

Step-by-step explanation:

1 ft = 1.894 * 10^-4 miles , so

1 inch = 1.894 * 10^-4 / 12  miles

= 0.15783 * 10^-4

= 1.5783* 10^-5 miles  ( in scientific form).

Multiplying this by 20 we get

31.567 * 10^-5

= 3.1567 * 10^-4 miles.

The scores on a statistics test had a mean of 81 and a standard deviation of 9. One student was absent on the test day, and his
Rama09 [41]

Using the definitions of the mean and of the standard deviation of a data-set, we have that:

  • The mean would increase.
  • The standard deviation would remain constant.

<h3>What are the mean and the standard deviation of a data-set?</h3>

  • The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.
  • The standard deviation of a data-set is given by the <u>square root of the sum of the differences squared between each observation and the mean, divided by the number of values</u>.

When the measure of 84 is added to the data-set, we have that:

  • A measure greater than the mean is added, hence the mean would increase.
  • The difference squared between 84 and the mean of 81 is of 9, which is the same as the standard deviation, which would remain constant.

Suppose that y varies inversely with x. Write an equation for the inverse variation. y = 2 when x = 5
Colt1911 [192]
Inverse means 1 over the other so y=1/x, we are given that y=2 when x=5 so our equation turns into 2=/=1/5, these things do not equal so we have to add a coefficient to the right to make this statement true. I would select 10, so that it becomes y=10/x, when the values are plugged in it becomes 2=10/5 or 2=2.
