Which of the following choices is a good estimate for the slope of the Line of Best Fit in the scatter plot?

svetoff [14.1K]

Answer:

A good estimate for the slope is 95/60

Step-by-step explanation:

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

From the graph take the points

(0,0) and (80,125)

substitute

$m=\frac{125-0}{80-0}$

$m=\frac{125}{80}$

simplify

$m=\frac{25}{16}$

Multiply by 3.75 both numerator and denominator

$m=\frac{25*3.75}{16*3.75}$

$m=\frac{93.75}{60}$

$m=\frac{94}{60}$

therefore

A good estimate for the slope is 95/60

After 5 throws in a game of darts, Brent's mean score was 32. Calculate his total score.

ehidna [41]

1.To know this answer, we need to know some vocabulary that's used in t. Most people don't know how to solve questions if they have hard Vocabulary and what the question is Asking

Mean=The average of all his throws

It's asking us to calculate his total score

2. Find Clues to help you solve word problems

Finding clues in Word Problems is a very important part a lot of people skip but this helps you solve the question easier

5 throws and Mean Score is 32 are the clues

3. Guess and check

The method to this thingy is called guess and check. There is another method which is slightly harder and i just don't want to do it.

Let's just say his scores were... 5, 6, 4, 5,10Add them up and you get 30Then 30/5

Let's try bigger numbers

20+25+20+20

If you like this method, you may try it another method is called work Backwards

5x32=160

Then divide 160 by 5 to double check and you get 32!!

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

Therefore, the answer s 160 as his total score

hope this gives you a clue to what we are doing and when you have a question like this, I really hope you understand the concept

Hope this helped (:

Diana paints 150 fence posts and chuck paints 130 fence posts. Diana paints 10 more fence posts than chuck. How many fence posts

statuscvo [17]

Complete Question

The complete question is shown on the first uploaded image

Answer:

Step-by-step explanation:

From the question we are told that

The relationship is $\frac{150 }{d} = \frac{130}{c}$

The number of fence post painted by chuck is $l = 130$

The number of fence post painted by Diana is $k = 150$

can paint 10 fences more than chuck so let say the of fence painted in an hour by chuck is $g$

Then the number of fence post painted by Diana in one hour is

$f = g+ 10$

So

$\frac{150 }{ g + 10 } = \frac{130}{g}$

$130 g + 1300 = 150g$

$g = 65 \ m$

4,200 with a 35% markdown

Bumek [7]

Answer:

4200 with 35% markdown: 2730

5000 with 44% markdown: 2800

Step-by-step explanation:

To calculate the price of an item including the markdown, multiply the original price by (1 minus markdown).

Convert the markdown percentage to decimal form before subtracting.

4200 with a 35% markdown: (35% = 0.35)

4200*(1 - 0.35)

= 4200 *(0.65)

= 2730

5000 with a 44% markdown: (44% = 0.44)

5000*(1 - 0.44)

= 5000*(0.56)

= 2800

Therefore, the sale price for $4200 with a 35% markdown is $2730, and the sale price for $5000 with a 44% markdown is $2800.

In what 3 forms can probability be written?

Romashka [77]

Answer:

unlikely,likely,and certain

Step-by-step explanation:

The probability of an event can only be between 0 and 1 and can also be written as a percentage. The probability of event A is often written as P ( A ) P(A) P(A)P, left parenthesis, A, right parenthesis.Probability. Probability is the likelihood or chance of an event occurring. For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½ .Examples of Probability. ... Probability can be expressed in a variety of ways including a mathematically formal way such as using percentages. It can also be expressed using vocabulary such as "unlikely," "likely," "certain," or "possible." Explore several probability examples.And an event is one or more outcomes of an experiment. Probability formula is the ratio of number of favorable outcomes to the total number of possible outcomes. Measures the likelihood of an event in the following way: - If P(A) > P(B) then event A is more likely to occur than event B.
