The range of scores in Ms. Biren’s class is greater than the range of scores in Mr. Hayes’s class.

This would mean there was likely more variety (variability) in Ms. Biren's class than Mr. Hayes's, which is what we know.

Naddik [55]

<h3><u>Question:</u></h3>

Jabari is power washing houses for a summer job. For every job, he charges an initial fee plus $30 for each hour of work. His total fee for a 4 -hour job, for instance, is $170 . Jabari's total fee,f, for a single job is a function of the number,t, of hours it takes him to complete the job. Write the function's formula.

<h3><u>Answer:</u></h3>

f = 50 + 30t is the function formula for total fee of Jabari

<h3><u>Solution:</u></h3>

Let the initial fee be "x"

Let "t" be the number of hours invested in that work

Let "f" be the total fee of Jabari

He charges and initial fee plus 30$ for each hour of work

Therefore, total fee is given as:

Total fee = initial fee + 30(number of hours)

$f= x + 30t$

Thus the function formula is found

<h3><u>Find the initial fee:</u></h3>

Given that,

His total fee for a 4 -hour job, for instance, is $170

Therefore,

t = 4

f = 170

Thus we get,

$170 = x + 30(4)\\\\170 = x + 120\\\\x = 170 - 120\\\\x = 50$

<em><u>Thus the formula becomes,</u></em>

$f = 50+30t$

Thus the total fee is a function of number of hours it takes him to complete the job

The sum of two numbers is -16 One number is seven times the other find the numbers

Allushta [10]

Answer:

The answer is -2 + (-14) = -16

Step-by-step explanation:

Let a = first number or the number is seven times "the other"

Let b = second number or "the other"

We have

a + b = -16

a = 7b

So we subtitie a = 7b to a + b = -16 which generate:

7b + b = -16

8b = -16

b = -2

We know the other number is -2, we need to find the second number

a = 7b

a = 7(-2)

a = -14

Thus the numbers are -2 and -14

How do you write this in point-slope and standard form?

g100num [7]

Answer:

Step-by-step explanation:

As we move from the point (2, 4) to the point (3, 6), x increases by 1 and y increases by 2. Thus the slope of the line connecting these two poins is m = rise/run = 2/1, or just 2.

Use the basic point-slope equation: y - k = m(x - h). Substitute 2 for x, 4 for y and 2 for m:

y - 4 = 2(x - 2). This is the desired equation in point slope form.

To find the equation in standard form, perform the multiplication as follows:

y - 4 = 2x - 4. We want this to look like Ax + By = C.

Thus, subtract 2x from both sides:

-2x + y = -4, or

2x - y = 4 This is the desired equation in Standard Form.
