A student‘s test score is likely to increase about 20 points for each hour of studying

Step-by-step explanation:

We can see that the indepedent value is hours spent studying and dependent value is test scores.

As the hours of studying get greater, so does the test scores. So it has to be either the second to last or last one.

If you pay attention to the numbers, you’d see that the last one would be the answer.

Answer:

last one

Step-by-step explanation:

each hour spent studying increases the by around 20 points. the slope of the line is 20.

Answer:

c. 25

Step-by-step explanation:

According to the intersecting chords theorem, the product of the segments of a chord equals the product of the segments of the other chord it intercepts.

Thus:

3*x = 5*15

3x = 75

x = 75/3

x = 25

Answer:

The required least amount of time a student in the class could have spent watching tv that day is 0-29 minutes

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
in the bar graph, represents the results of a survey in which students stated the number of minutes they'd spent watching TV the previous day.

The least amount of time is shown by the first bar and which is 0-29 minutes.

Thus, the required least amount of time a student in the class could have spent watching tv that day is 0-29 minutes

Answer:

35 cars

Step-by-step explanation: ok so here is how you do it you divide 15 and 3 to find out how much cars Tim washed in one hour so in this case we got 5 then we multiply the hours by 7 and we get 35 cars

Answer:

I believe the answer is 35.

Step-by-step explanation:

15+15=30

30+5=45

1 hour = 5 cars

3 hours = 15 cars

6 hours = 30 cars

7 hours = 35 cars

15 divided by 3 = 1

so yeah hope this helps you.

Answer:

2) 2x + 6

3) 8x - 2

4) 5x - 8

Step-by-step explanation:

The quotient of expression (18x²+15x) divided by 3x is 6x+5.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

A quotient is a quantity produced by the division of two expressions.

Here,

A) (18x²+15x)÷3x

Now, 3x(6x+5)/3x

= 6x+5

B) (16x²+48x)/8x

= 8x(2x+6)8x

= (2x+6)

C) (56x²-14x)/7x

= 7x(8x-2)/7x

= 8x-2

D) (20x²-32x)/4x

= 4x(5x-8)/4x

= 5x-8

Therefore, the quotient of expression (20x²-32x) divided by 4x is 5x-8.

Answer:

P22039

Step-by-step explanation:

Cost of new television = 29078

Let the price of old model television = x

2x - 15000 = 29078

2x = 29078 + 15000

2x = 44078

2x/2 = 44078 /2

x = 22039

Hence, price of old model television is P22039

Answer: B. The procedure for constructing the confidence interval is robust. The larger the sample​ size, the more resistant the mean.​ Therefore, the confidence interval is more robust.

Step-by-step explanation:

Large sized data samples usually have more stability than data with small samples, they yield a mean value which edges closer to the value of the population data. This means that large size data samples will have a mean which is more resistant to change than samples with a lower sample size. The confidence interval gives robustness while constructing a model by giving te leverage for a range of values based in a certain level of confidence upon which a statistical vale can be tested for validity.

Answer:

380 cubic inches

Step-by-step explanation:

The basic formula is length x width x height, so it's pretty simple, you just do 4 x 19 x 5! The order doesn't matter as long as it's just the length worth and height

I, sometimes do length x width, then use the answer for that and multiply it by the height (So that I can break it down)

Answer:

length of the sheet of paper is 11 in.

Step-by-step explanation:

Let "a" = short end of paper and let "b" = long end of paper.

Let "p" = perimeter

1st equation:   p = 39"

2nd equation:  2a + 2b = p   plug in "39" for diameter;  result:

2nd equation:  2a + 2b = 39

3rd equation:  b = 2a - 6

replace "b" in 2nd equation with "2a - 6" from 3rd equation, result:

2a + 2(2a - 6) = 39  simplified to:

2a + 4a - 12 = 39    simplified to:

6a - 12 = 39            simplified to:

6a = 51                   simplified to:

a = 51/6  =  8.5

so, a =  short end of paper = 8.5 inches

In 3rd equation (b = 2a - 6), substitute "a" with "8.5"

3rd equation becomes:   b = 2(8.5) - 6    simplified to:

b = 17 - 6  =  11

so, b = long end of paper = 11 inches

answer to question is:  dimensions of paper are ---

8.5 inches wide by 11 inches long

Answer:

The answer is 11

Step-by-step explanation:

So perimeter is base+ base+length+length. Therefore you take 8.5+8.5 which is 17 and subtract it from 39 to get 22. You take 22 and divide it by 2 which leaves you with 11.
