Answer:

3y = 8x + 18

for y-intercept let x = 0

3y = 8(0) + 18

3y = 18

y = 6

y-intercept is (0, 6)

THIS IS TRUE

Answer:

Step-by-step explanation:

To find the population variance, we first need the mean:

[tex]\bar{x}=\frac{4+6+8+9+9}{5}=\frac{36}{5}=7.2[/tex] so the mean is 7.2. To find the population variance (which is almost exactly the same as the sample variance except for a small difference in the denominators of the formula) we have to take each number minus the mean, and then square the difference. Add together all these squared numbers and then divide by the number of numbers. Like this:

[tex](4-7.2)^2=10.24\\(6-7.2)^2=1.44\\(8-7.2)^2=.64\\(9-7.2)^2=3.24\\(9-7.2)^2=3.24[/tex]

Add together those numbers and divide them by 5:

[tex]\sigma=\frac{10.24+1.44+.64+3.24+3.24}{5}=\frac{18.8}{5}=3.76[/tex]

Answer: I think Plan A is the cheapest

Step-by-step explanation:

I would say this because all it is is a 10 cent incline and 30 dollars cheaper, meaning it would take almost 15 weeks to earn 30 dollars on the plan a, while plan b will already be at like 100 Dollars.

Answer:

x+n

Step-by-step explanation:

The expression for another number will be 25 - x.

An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.

In other meaning, expression is very useful to determine the end or root value of constraint.

For example 3x +5y

The constraint of expression is represented as = or <, >.

Let's say another number is y

Then,

Sum of both number

x + y = 25

y = 25 - x

Hence "The expression for another number will be 25 - x".

[tex]19+1,5(10m-8)=127\\\\19+15m-12=127\\\\15m+7=127 \ \ /-7\\\\15m=120 \ \ /:15\\\\\huge\boxed{m=8}[/tex]

Answer:

[tex]m=8[/tex]

Step-by-step explanation:

[tex]19 + 1.5(10m-8) = 127[/tex]

Multiply both sides by 10

[tex]190+15(10m-8)=1270[/tex]

Subtract 190 from both sides

[tex]15(10m-8)=1080[/tex]

Divide both sides by 15

[tex]10m-8=72[/tex]

Add 8 to both sides

[tex]10m=80[/tex]

Answer:

x = 27.42

Step-by-step explanation:

To find the value of x

a segment will be 180 degrees so now we can easily find the value of x

2x + 1 + 5x - 13 = 180   (line segment is 180 degrees)

7x  - 12 = 180

7x = 180 +12

7x = 192

x = 192/7

x = 27.42

Answer:

Governments, need to know how many inhabitants currently live in the country and how many there will be in the future. From this they can plan and make better decisions regarding the construction of schools, hospitals, roads, and more.

The expression that represents the change in temperature for Day 1 is 23oF - (-8oF) and the value is 31oF

The given parameters from the question are:

Initial Temperature = -8oF

Final Temperature = 23oF

The expression that represents the change in temperature for Day 1 is represented as:

Change in temperature = Final Temperature - Initial Temperature

Substitute the known values in the above equation

Change in temperature = 23oF - (-8oF)

Remove the brackets

Change in temperature = 23oF + 8oF

Evaluate the sum

Change in temperature = 31oF

Hence, the expression that represents the change in temperature for Day 1 is 23oF - (-8oF) and the value is 31oF

The changeover to sleet will happen at 10:30pm

The changeover to sleet is predicted to occur at 10:30 pm.

Given,

The temperature outside is dropping at a rate of 1.5 degrees each hour.

The changeover from rain to sleet is when the temperature reaches 32*F or below.

Currently, the temperature is 53*F and the time is 8:30 am.

We need to find at what time can we predict the changeover to sleet will occur.

Temperature is the measure of the hotness or coldness of an object with reference to some standard value.

We have,

Current temperature = 53*F at 8:30 am.

Rate of the drop of temperature = 1.5 degrees per hour.

Find the number of hours needed to drop from 53*F to 32*F.

53*F - 32*F = 21*F

We need to find how many hours required to drop to 21*F

1 hour = 1.5 degrees

Multiplying 21/1.5 on both sides.

21/1.5 x 1 hour = 21/1.5 x 1.5 degrees.

14 hours = 21 degrees

The number of hours required to drop from 53*F  to 32*F is 14 hours.

8:30 am + 14 hours = 10:30 pm

Thus the changeover to sleet is predicted to occur at 10:30 pm.
