y-intercept of –7 and a slope of 3/2

Answers

Answer:

y=3/2x-7

Step-by-step explanation:

Slope-intercept formula: y=mx+b

m= slope

b= y-intercept

Replace the "m" and "b" the number that is given it

So the slope of 3/2 will look like this in the equation:

y=3/2x+b

THe y-intercept of -7 will look like this in the equation with the slope:

y=3/2x-7

What is the solution of the equation 2X = 7? Round your answer to the nearest ten-thousand.

Answers

Answer:

x =2.8074

Step-by-step explanation:

2^x = 7

Take the log of each side

log (2^x) = log (7)

We know  log a^b = b log a

x log 2 = log 7

x = log (7) / log 2

x =2.80735

To the nearest tenth thousandth

x =2.8074

The average rate of change is $0.50, meaning that for each minute of talk time, the monthly bill increases by $0.50.
The average rate of change is $0.50, meaning that for every ten minutes of talk time, the bill increases by $0.50.
The average rate of change is $0.05, meaning that for each minute of talk time, the monthly bill increases by $0.05.
The average rate of change is $0.05, meaning that for every ten minutes of talk time, the bill increases by $0.05.

Answers

Answer:

for each 1 minute of talk time, the bill goes up 5¢.

I think it has to either be

--The average rate of change is $0.05, meaning that for each minute of talk time, the monthly bil increaes by $0.05

or

--The avaerage rate of change is $0.05, meaning that for every ten minutes of talk time, the bill increases by $0.05

Answer:

C. The average rate of change is $0.05, meaning that for each minute of talk time, the monthly bill increases by

Step-by-step explanation:

Average rate of change during 40 min:

(21.95 - 19.95)/40 = 2/40 =$0.05

This number reflects the average cost of talk for each minute

Answers

Answer: 5(a-5d)

Step-by-step explanation:

The GCF (the largest number that can be factored evenly out of the expression is 5. Thus, we divide out 5 from the expression, leaving a and -5d inside of the paranthesis.

We can check our work by redistributing 5 to the factor within the parenthesis. This will prove whether or not your factoring is correct. In this case, taking out the 5 is the correct factorization.

Jesse makes a 6% commission on every spa where makes if he sold $875 worth of items this week, how much will he make in commission

Answers

Answer:

$52.50

Step-by-step explanation:

6% of 875

0.06*875

   52.5

Jesse will make $52.50 in commission this week if he sold $875 worth of items.

What is the percentage?

The percentage is the ratio of the composition of value to the whole composition of value multiplied by 100.

Here,
To calculate Jesse's commission, we can multiply the total sales by the commission rate:

Commission = Total Sales × Commission Rate

In this case, the total sales are $875 and the commission rate is 6%, so:

Commission = $875 × 6% = $52.50

Therefore, Jesse will make $52.50 in commission this week if he sold $875 worth of items.

Answers

Answer:  y = 3x+18

Slope = 3

Y intercept = 18

==================================================

Work Shown:

m = slope

m = (y2-y1)/(x2-x1)

m = (0-(-9))/(-6-(-9))

m = (0+9)/(-6+9)

m = 9/3

m = 3 ... is the slope

-------

y = mx+b

y = 3x+b .... plug in the slope

-9 = 3(-9)+b ... plug in the point (x,y) = (-9,-9)

-9 = -27+b

-9+27 = -27+b+27 .... adding 27 to both sides

18 = b

b = 18 ... is the y intercept

---------

We found that m = 3 is the slope and b = 18 is the y intercept

y = mx+b turns into y = 3x+18

The titanium content of an alloy is being studied in the hope of ultimately increasing the tensile strength. An analysis of six recent heats chosen at random produces the following titanium contents. 9.7% 7.4% 5.9% 7.7% 7.5% 8.9% What is the value of the test statistic, if the alternative hypothesis is the mean titanium content is greater than 9.5%?

Answers

Answer:

Tstatistic = - 3.068

Step-by-step explanation:

Given the data: 9.7% 7.4% 5.9% 7.7% 7.5% 8.9%

Mean titanium > 9.5%

Test statistic :

(m - μ) / (s/√n)

From the data: obtain the sample mean and standard deviation

From the data given ;

Calculate the same mean and standard deviation :

Using calculator :

Sample mean (m) = ΣX / n

Sample size (n) = 6

m = 47.1 / 6 = 7.85

Standard deviation (s) :

Using calculator = 1.317

Hence,

(m - μ) / (s/√n)

Tstatistic = (7.85 - 9.5) / (1.317/√6)

Tstatistic = - 1.65 / 0.5376629

Tstatistic = - 3.068
