Answer:

the critical value for r at r_{0.05, 23} = 0.396

Step-by-step explanation:

Given that:

the linear correlation coefficient r = 0.767

the sample size n = 25

the level of significance ∝ = 0.05

The degree of freedom is expressed with the formula df = n - 2

 df = 25 - 2

 df = 23

the critical value for r at r_{0.05, 23} = 0.396

The linear correlation coefficient r = 0.767 is not in the region between the critical values of -0.396 and +0.396. We can therefore conclude that the linear correlation coefficient is significant.

H+p=4(k−7) for k please answer
dmitriy555 [2]

Answer:

(28 + h + p)/4 = k

Step-by-step explanation:

Step 1: Write equation

h + p = 4(k - 7)

Step 2: Solve for <em>k</em>

<u>Distribute 4:</u> h + p = 4k - 28

<u>Add 28 to both sides:</u> 28 + h + p = 4k

<u>Divide both sides by 4:</u> (28 + h + p)/4 = k

George would like to build a garden this year, George measure out his proposed garden and would like to know how many square fee
Blababa [14]

Answer:

The area is 105.5ft^2

Step-by-step explanation:

Required

The area of the composite figure

The figure can be divided to 2 shapes

(1) Rectangle: Length = 6ft and Width = 8ft

(2) Trapezoid: Height = 5ft (i.e. 8 - 3), Parallel sides = 9ft and 14ft (i.e. 20 - 6)

The area of the rectangle is:

Area = 6 * 8 = 48

The area of the trapezoid is:

Area = \frac{1}{2}(9 + 14) * 5

Area = \frac{1}{2}(23) * 5

Area = 11.5 * 5

Area = 57.5

So, the area of the garden is:

Total = 48 + 57.5

Total = 105.5

Given

Mr. Claussen needs 15 Pounds of ground beef

It is stated that 2 pounds of beef cost $4.40

Using unitary method

1 Pound cost  \frac{4.4}{2}=\$2.2

For 15 pounds it is

\Rightarrow 15\times 2.2=\$33

Thus, he has to spend $33 for 15 pound meat
