A newspaper collected information on schools in its circulation area in order to compare their quality. Two measures the newspaper collected for each school, mean class size and mean score on a statewide reading exam, are shown in the scatterplot. One school in the report, Springside Elementary, is labeled in the graph.

Which is a true statement regarding Springside?
Springside does not affect the correlation.
Springside weakens the correlation shown in the scatterplot.
Springside strengthens the correlation shown in the scatterplot.
Removing Springside would increase the value of the correlation coefficient.

The line appears to intersect the origin (0,0) and (2.5,12.5).

Slope is rise over run, so if you take the difference in y value and divide it by the difference in x value, you get the slope.

Answer:a 750g bag is better.

Step-by-step explanation: 3 bags would be more G the 2kg and less money 0.23/100 grams 700 g would be 1.4$ for that so 750 g is the best.

Answer:

750 grams at $1.39

Step-by-step explanation:

To make it easy to see, determine how much each option costs per gram.

750 grams cost 1.39.  Divide 1.39 by 750 which gives you 0.001853

2 kg is 2000 grams costing 3.99.  Divide 3.99 by 2000 which give you 0.001995

100 grams cost $0.23.  Divide 0.23 by 100 which gives you 0.0023

So the 750 grams is the best price.

Step-by-step explanation:

7+8 = 15

[tex] \sf \sqrt{x + 3 = 12} [/tex]

[tex] \sf = \sqrt{x = 12 - 3} [/tex]

[tex] \sf = \sqrt{x = 9} [/tex]

[tex] \sf = \sqrt{9} [/tex]

[tex] \sf = \sqrt{3 \times 3} [/tex]

= 3

The solution of the linear equation [tex]\sqrt{x+3} = 12[/tex]  for the variable, x is 141.

Two algebraic expressions separated by an equal symbol in between them and with the same value of the expression are called equations.

Example = 2x +4 = 12

here, 4 and 12 are constants and x is variable

The solution of the equation can be calculated as:

[tex]\sqrt{x+3} = 12[/tex]

Squaring both side,

[tex]x+3 = (12)^2[/tex]

x+3 = 144

Subtract 3 from both the sides,

x = 141

The solution of the linear equation for the variable x is 141.

Step-by-step explanation:

Answer:

1) 350

2) 195.83

Step-by-step explanation:

Tuition fee = $12, 000 per year.

30% of it's being paid off by the scholarship, so she'll have to pay:

[tex] = 12000 - ( \frac{30}{100} \times 12000) [/tex]

[tex] = 12000 - 3600[/tex]

[tex] = 8400[/tex]

She'll have to pay $ 8400 by herself, her savings.

If she's saving $ 8400 for two years, she's actually saving $ 8400 for 24 months!

for one month, it'll be

= 8400/ 24

= $ 350 per month

one year fee = $ 10, 700

uncle pays half of it, I.e., 10700/ 2

= $ 5, 350

he gets a grant for $ 3,000

so, the part of the fee he ain't paying

= 5,350 + 3000

= $ 8,350

So, he'll have to save:

= 10,700 - 8,350

= $ 2,350

that is per year,

for per month = 2350/ 12

= $ 195.83

Answer:

A. 81 cents per ounce

B. 75 cents per ounce

C. The 16 ounce package would be a better buy.

Step-by-step explanation:

A. 8.11/10 = 0.811

B. 12/16 = 0.75

C. Each ounce is cheaper in the 16 ounce package.

Answer:

Option C.

Step-by-step explanation:

First, simplify the inequality. Add 2 to both sides:

4v - 2 < 10

4v - 2 + 2 < 10 + 2

4x < 12

Divide both sides by 4:

4x ÷ 4 < 12 ÷ 4

x < 3

As 3 will not satisfy the inequality, it is not a solution. The option that shows x being less than 3 but not including is option C.
