What is the y-intercept of the trend line, to the nearest hundredth?

Answers

Answer 1

Answer:

-23.21

there should be a two part for this and the answer would be D y= 0.15x - 23.21

Step-by-step explanation:

Answer 2

The line of best will be y = 0.15x - 23.21  and the y-intercept is -23.21 after applying the formula.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

The data is given:

R(x)     W(y)

808     93

768     94

655     66

684     81

637     86

619     75

613     61

609     69

563     55

The line of best fit can be written as:

y = mx + c

Here m is the slope of the line best fit and c is the y-intercept

Putting the values in the formula we get:

m = 0.15

c = -23.21

The line of best fit is:

y = 0.15x - 23.21

Thus, the line of best will be y = 0.15x - 23.21  and the y-intercept is -23.21 after applying the formula.

PLEASE CAN YOU EXPLAIN LIKE A BIG PARAGRAPH OF HOW YOU WILL DO IT PLEASE RIGHT NOW LIKE A BIG PARAGRAPH THANK YOU

Answers

Answer:

Ok you're talking about "PI"

Area of a circle:

πr^2

What that basically means is

π <- That sign is 3.14

You wanna times that with the radius (r).

The radius is half of the diamater so divde the diameter by 2 then mutiply whatever u get with 3.14

Then the final step is do 3.14 x radias then times 2.

That's it :D

17 and 59

Step-by-step explanation:

90-75=17 first one

180-121=59 second one plz give me brainnessttttt pllzzzz

Hey there!

So the first angle is a complementary angle, meaning that two angles put together will equal 90 degrees. Since we already know that one angle is 75 degrees, all we need to do is 90-75 and we get 15 degrees, which is the value of the missing angle.

The second angle is a supplementary angle, which means two angles equal 180 degrees. Since we know that one angle is 121 degrees, we can take that and subtract is from 180 degrees to get 59 degrees, which is the value of the missing angle.

Remember:

A complementary angle is made of up TWO angles that add up to 90 degrees.

A supplementary angle is made up of TWO angles that add up to 180 degrees.

a negative times a negative is a positive and squaring those numbers would be multiplying a negative by itself.

For example (-2)*(-2) is 4

**note, this only applies if the negative value is in the parentheses. (-2)^2 is different than -2^2 because with -2^2 only the 2 is getting squared and then you’d have to multiply the negative after**

-3                     -3^3 = -3 • -3 • -3 = -27

-4                     -4^3 = -4 • -4 • -4 = -64

-5                     -5^3 = -5 • -5 • -5 = -125

-6                     -6^3 = -6 • -6 • -6 = -216

Frank invests $1,000 in simple interest investment account that pays 8% a year. After a number of years, he withdraws his balance of $2,200. Using the formula I = P r t, how many years was his money invested? Work backwards-but find the Interest first!

Answers

Answer:

15 years

Step-by-step explanation:

Given data

P=$1,000

R=8%

A= $2200

I= A-P

I=2200-1000

I=$1200

Applying the formula

I=PRT/100

1200=1000*8*T/100

cross multiply

1200*100= 8000T

120000= 8000T

divide both sides by 8000

T=120000/8000

T=15  years

Hence the time is 15 years

yd2

Answers

Answer:

64 square yards

Step-by-step explanation:

If the room is a square, then all sides of the room should be equal. To find the area of the room, we would need to multiply 2 adjacent sides of the room, meaning 24 x 24 = 576. Since we need yards of carpet, not feet, and we know that 1 square yard is 9 square feet, we divide our total area in feet by 9. This gives us 64sq yards of carpet

A recent survey suggests that 47% of all televisions are connected to the internet, 32% are voice controlled, and 22% are both connected to the internet and voice controlled. Suppose a television is selected at random and it is voice controlled. What is the probability that a randomly selected voice-controlled television is also connected to the internet?

0.15
0.47
0.69
0.79

Answers

It suppose to be 0.47

The probability that a randomly selected voice-controlled television is also connected to the internet is 0.69.

Option C is correct.

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

let P(V) is the probability of selecting a voice controlled television

and, P(I) is the probability that a selected television is connected to the internet.

So, the probability that a randomly selected voice-controlled television is also connected to the internet

P(I|V) = P(I ∩ V)/P(V)

P( I ∩ V) = 22%

P(V) = 32%

So, P(I|V) = 22%/32% = 0.6875

Answer: B. 55

---------------------------------------------------------------------------------------

Given

(2x+15)+x=180

Expand parenthesis

2x+15+x=180

Combine like terms

3x+15=180

Subtract 15 on both sides

3x+15-15=180-15

3x=165

Divide 3 on both sides
