The table shows test scores for six students. Do the data show a positive or a negative correlation? Can the data be used to show causation?
​

Answer:

40

Step-by-step explanation:

16 is 40 percent that means that :

32 is 80 percent

8 is 20 percent.

32 + 8 is 40 ------  80 percent+ 20 percent =100 percent

40 is the number whose 40% is 16.

percentage, a relative value indicating hundredth parts of any quantity.

We need to find the number whose 40% is 16.

Let us consider the number be x.

Convert 40% to the decimal by dividing with 100

40/100=0.4

Now multiply zero point four with x which gives 16

0.4x=16

Divide both sides by 0.4

x=16/0.4

x=40

Hence, 40 is the number whose 40% is 16.

The Volume of triangular prism

                     V = 450 cm³

Step-by-step explanation:

Explanation:-

Given The area of cross section of a prism A = 45cm²

and     height (h) = 10 cm

The Volume of triangular prism

                V = ( Base area X Height )

                    =  45 X 10

                    = 450 cm³

The Volume of triangular prism

                     V = 450 cm³

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that:

The population mean μ = 900

The sample size n = 53

The sample mean = 841

The standard deviation = 190

The level of significance = 0.01

To test the claim that the mean balance of the accounts has decreased during the period.

The null and the alternative hypothesis can be computed as:

[tex]H_o : \mu \ge 900 \\ \\ H_1 : \mu < 900[/tex]

This is a left-tailed test since the alternative is less than 900

The test statistics can be computed as:

[tex]Z = \dfrac{\overline x - \mu}{\dfrac{s}{\sqrt{n}} }[/tex]

[tex]Z = \dfrac{841 -900}{\dfrac{190}{\sqrt{53}} }[/tex]

[tex]Z = \dfrac{-59}{\dfrac{190}{7.28}}[/tex]

Z = -2.26

The p-value = P(Z < -2.26)

From the z-tables

The p-value = 0.01191

The p-value ≅ 0.012

Decision rule: To reject the null hypothesis if the significance level is > p-value.

We failed to reject the null hypothesis.

Conclusion: Thus, there is insufficient evidence to conclude that such accounts mean balance has decreased during this period.

Answer: 15 gallons .

Step-by-step explanation:

Step 1

4 quarts = 1 gallon

therefore 60 quarts = (60 quarts x 1 gallon) / 4 quarts

= 15 gallons .

Step 2-- The converted amount which is 15  has fewer units than the original which is 60.

Answer for the first equation:

(7, -1)

Step-by-step explanation:

Original Equation: 5(x - 3y) - 2x = 6 When x = 3y

Substitute in the 3y for x:

5(3y - 3y) - 2(3y) = 6

5(0) - 6y = 6

-6y = 6

y = -1

Plug -1 in for y in the original equation:

5(x -3(-1)) - 2x = 6

5(x + 3) - 2x = 6

5x + 15 - 2x = 6

3x + 15 = 6

3x = -9

x = -3

Answer:

520

Step-by-step explanation:

Given that:

Profit function p(x) is :

P(x) = 8.50x- 1500

If the profit made = $2920 ; the number of pizza kits sold is :

Then p(x) = 2920

Putting p(x) = 2920 in the equation :

2920 = 8.50x - 1500

2920 + 1500 = 8.50x

4420 = 8.50x

Divide both sides by 8.50

4420 / 8.50 = 8.50x / 8.50

520 = x

Hence, number of pizza kits sold is 520
