The initial value is how much he starts out with, and it says he has $32
So the initial value is B, $32

I believe the initial value is the original/first amount he had which would be $32.

Write the equation of the line in slope-intercept that has passes through the points (2,-5) and (8, 13).

const2013 [10]

Answer:

The equation of the straight line in Slope- intercept form

y = 3 x - 11

Step-by-step explanation:

Explanation:-

Given points are (2,-5) and (8, 13)

The Slope of the line

$m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} } = \frac{13-(-5)}{8-2} = \frac{18}{6} =3$

Equation of the line having slope 'm' and given point

$y - y_{1} = m (x - x_{1} )$

(x₁ , y₁) = ( 2, -5 )

$y - (-5) = 3 (x - 2 )$

y + 5 = 3x - 6

The equation of the straight line in slope intercept form

y = m x + c

y = 3 x - 6-5

y = 3 x - 11

Final answer:-

The equation of the straight line in Slope- intercept form

y = 3 x - 11

tekilochka [14]

Answer:

$B2 = 0.465$ --- Population standard deviation

$C2 = 0.216$ --- Population Variance

Step-by-step explanation:

Given: Wake-up time data

Required: Determine the population standard deviation and the population variance using Excel

First, enter the given data in Excel

For this question, I entered the data in cell A2 through cell A21

Cell B2 and Cell C2 were used to hold the results of the population standard deviation and the population variance, respectively.

In cell B2, the formula to use is:

=ROUNDUP(STDEV.P(A2:A21),3)

The round function rounds the result to 3 decimal places while STDEV.P calculates the population standard deviation.

So, the result is:

$B2 = 0.465$

In cell C2, the formula to use is:

=ROUND(VAR.P(A2:A21),3)

The round function rounds the result to 3 decimal places while VAR.P calculates the population variance.

So, the result is:

$C2 = 0.216$

To determine the ________ of an event, you can use the formula P(E) = n(E)/n(S), where n(E) is the number of outcomes in the eve

Semenov [28]

Answer:

Probability

Step-by-step explanation:

Probability of an event is how likely that event is to happen. And it is denoted by letter P and calculated by the formula below:

P(E) = number of possible outcome/number of the total event sample

P(E) = n(E) / n(S)
