many of the data points must lie on the regression line for the data set?
O A. 9
OB. 8
O C. 6
O D. 7

Answers

Answer 1

Answer: A

Step-by-step explanation:

The coefficient of determination is a number between 0 and 1 used to measure the level of precision with which the regression model created fits the data. A measure of means that the model explains the entire variation between the two variables without error.

Therefore, in this case, if  means that the 9 points are on the line

4. The diagram shows a right-angled triangular prism.

Answers

Answer:

a) 2260 cm³

b) 3390 grams

Step-by-step explanation:

3.

a)The radius of the solid cylinder = 6cm

The height of the cylinder is =20 cm

The volume = π*r²*h

The volume = 3.14 * 6²*20 =2260 cm³

b) Density of the material = 1.5 g/cm³

  Volume of the cylinder = 2261 cm³

  Mass of the cylinder = Density * Volume

  Mass of the cylinder = 1.5 * 2261 = 3390 grams

U right it’s not any of them and if u single I’m here

Answer:

B.

Step-by-step explanation:

AD, the entire segment, is composed of the three segments AB, BC, and CD. In other words:

[tex]AD=AB+BC+CD[/tex]

Since AB=CD, we can substitute:

[tex]AD=CD+BC+CD\\ AD=2CD+BC[/tex]

We know that CD is 9 and BC is 5x. AD is 53. So, substitute:

[tex]53=2(9)+5x[/tex]

Solve for x:

[tex]\begin{aligned} 53&=18+5x \\ 35&=5x \\ 7&=x \end{aligned}[/tex]

The value of x is 7.

Hence, our answer is B.

If you would like to venture further, you can check out my Instagram page (learntionary) where I post notes and mathematics tips. Thanks!

Answer:

General Form of Equation of a line that passes through the point (-8,6) and has a slope of 3/4 is:

[tex]\frac{3}{4}x-y+12=0[/tex]

Step-by-step explanation:

We need to find equation of line that passes through the point (-8,6) and has a slope of 3/4 in general form.

The general form of linear equation is [tex]Ax+By+C=0[/tex]

First we will use slope-intercept form i.e, [tex]y=mx+b[/tex] to find equation and then write it in general form.

Where m is slope and b is y-intercept.

We are given slope = 3/4 but y-intercept is not given and we need to find.

Finding y-intercept

Using the point (-8,6) and slope m = 3/4 we can find y-intercept

[tex]y=mx+b\\6=\frac{3}{4}(-8)+b\\6=3(-2)+b\\6=-6+b\\b=6+6\\b=12[/tex]

So, y-intercept b is 12

Equation of line

The line has slope m=3/4 and y-intercept b is 12, the equation is:

[tex]y=mx+b\\y=\frac{3}{4}x+12[/tex]

General Form of Equation of a line that passes through the point (-8,6) and has a slope of 3/4 is:

[tex]\frac{3}{4}x-y+12=0[/tex]

Draco invests $5000. Approximately how long will it take for the investment to double if the rate is 10% compounded annually?

Answers

Answer:

I'm in 6th grade and I think it is 500

For the investment to double if the rate is 10% compounded annually,

it will take about 7 years and 3 months.

What is compound interest rate?

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

x = P (1+r/n[tex])^{nt}[/tex]

,where x = compound interest

P = principal (the initial deposit or loan amount)

r = annual interest rate

n = the number of compounding periods per unit of time

t = the number of time units the money is invested or borrowed for.

Given:

Draco invests $5000.

Draco wants his investment to double.

That means, accrued amount = $10000

Interest rate = 10%

First, convert R as a percent to r as a decimal

r = R/100

r = 10/100

r = 0.1 per year,

Then, by using the formula,

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(10,000.00/5,000.00) / ( 1 × [ln(1 + 0.1/1)] )

t = ln(10,000.00/5,000.00) / ( 1 × [ln(1 + 0.1)] )

t = 7.273 years

t = about 7 years 3 months

Therefore, the required time is about 7 years 3 months.

that passes through the point, (-2,5) ?

Answers

The equation of a line is written as y = mx + b where m is the slope.

Replace M with the slope to get:

y = 1/2x + b

Now replace x and y with the given point to solve for b:

5 = 1/2(-2) + b

SImplify:

5 = -1 + b

Add 1 to both sides:

b = 6

The equation of the line is y = 1/2x + 6
