Marelize is a researcher at the Department of Agriculture. She has noticed that farmers across the country have very different crop yields depending on the region. She thinks that this has to do with the different climate in each region. In order to test her idea, she collected data on crop yield and average summer temperatures from a number of farmers. The scatterplot shows the data she collected on crop yield and the average summer temperature.answers.
a. There is a non-linear association between the amount of crop yielded and the average summer temperature.

b.There is a negative linear association between the amount of crop yielded and the average summer temperature.

c.There is no apparent association between the amount of crop yielded and the average summer temperature.

d.There is a positive linear association between the amount of crop yielded and the average summer temperature.

Answer:

288πin³

Step-by-step explanation:

Volume of a sphere is expressed as;

V = 4/3πr³

r is the radius = 6 inches

Substitute into the formula

V = 4/3π(6)³

V = 4/3π(216)

V= 864/3π

V = 288π in³

Hence the volume of the sphere is 288πin³

Answer:

13.73 hours

Step-by-step explanation:

On a map with a scale of

1 inch= 100 miles

the distance between two cities is 7.55 inches.

We convert from inches to miles

1 inch = 100 miles

7.55 inches = x

x = 7.55 × 100 miles

x = 755 miles

The distance between the two cities = 755 miles

If a car travels 55 miles per hour, about how long will it take to get from one city to another?

We are to calculate the Time

Speed = Distance /Time

Time = Distance/Speed

Hence, the time is calculated as:

755 miles/55 miles per hour

= 13.727272727 hours

≈ 13.73 hours

Answer:

(6x² - 22x + 20) square units

Step-by-step explanation:

The area of a rectangle is calculated as:

Length × Width

From the question

Length = (x - 2)2 = 2x - 4

Widths = 3x - 5

The area of the rectangle =

(2x - 4 ) × (3x - 5)

2x(3x - 5) -4(3x - 5)

6x² - 10x - 12x + 20

6x² - 22x + 20

The area of the rectangle =

(6x² - 22x + 20) square units

He earns $51.02

Step-by-step explanation:

If Michael earns an 8% commission, then he is paid 8% of what he sells it for. Therefore, he earns 8% of $637.75.

Your equation is y = 0.08 × 637.75

y = 51.02

He earns $51.02

Answer:

we conclude that:

[tex]3\sqrt{125}+4\sqrt{20}=23\sqrt{5}[/tex]    

Hence, the last option i.e. [tex]23\sqrt{5}[/tex] is correct.                      

Step-by-step explanation:

Given the expression

[tex]3\sqrt{125}+4\sqrt{20}[/tex]

Combining the radical expressions

[tex]3\sqrt{125}+4\sqrt{20}[/tex]

let us first solve

[tex]3\sqrt{125}[/tex]

[tex]=3\sqrt{5^3}[/tex]

[tex]=3\sqrt{5^2\cdot \:5}[/tex]

Apply radical rule:  [tex]\sqrt{ab}=\sqrt{a}\sqrt{b},\:\quad \:a\ge 0,\:b\ge 0[/tex]

[tex]=3\sqrt{5^2}\sqrt{5}[/tex]

Apply radical rule:   [tex]\sqrt{a^2}=a,\:\quad \:a\ge 0[/tex]

[tex]=3\cdot \:5\sqrt{5}[/tex]

[tex]=15\sqrt{5}[/tex]

Thus,

[tex]3\sqrt{125}=15\sqrt{5}[/tex]

similarly solving

[tex]4\sqrt{20}[/tex]

[tex]=4\sqrt{2^2\cdot \:5}[/tex]

Apply radical rule:  [tex]\sqrt{ab}=\sqrt{a}\sqrt{b},\:\quad \:a\ge 0,\:b\ge 0[/tex]

[tex]=4\sqrt{2^2}\sqrt{5}[/tex]

Apply radical rule:   [tex]\sqrt{a^2}=a,\:\quad \:a\ge 0[/tex]

[tex]=4\cdot \:2\sqrt{5}[/tex]

[tex]=8\sqrt{5}[/tex]

Thus,

[tex]4\sqrt{20}=8\sqrt{5}[/tex]

so we get

[tex]3\sqrt{125}=15\sqrt{5}[/tex]

[tex]4\sqrt{20}=8\sqrt{5}[/tex]

so the expression becomes

[tex]3\sqrt{125}+4\sqrt{20}=15\sqrt{5}+8\sqrt{5}[/tex]        ∵ [tex]3\sqrt{125}=15\sqrt{5}[/tex] , [tex]4\sqrt{20}=8\sqrt{5}[/tex]

                        [tex]=23\sqrt{5}[/tex]                   ∵ [tex]15\sqrt{5}+8\sqrt{5}=23\sqrt{5}[/tex]

Therefore, we conclude that:

[tex]3\sqrt{125}+4\sqrt{20}=23\sqrt{5}[/tex]    

Hence, the last option i.e. [tex]23\sqrt{5}[/tex] is correct.                    

Answer:

12/3 or 4 hours

Step-by-step explanation:

Given,

[tex] - 98 = - 7h[/tex]

[tex] \implies \: - 7h \: = - 98[/tex]

[ Firstly, Arrange it ]

Now,

[tex] \implies \: h = \cancel\dfrac{ - 98}{ - 7} [/tex]

minus sign minus sign are also canceled.

[tex] \implies \: h \: = 14[/tex]

hence,the value of h is 14 .

Answer:

Step-by-step explanation:

4050 = 2900 (1 + 0.028/4)^4t

4050 = 2900 (1.007)^4t

Divide all by 2900

1.3965517 = 1.007^4t

TURN LOG

log (1.3965517) = log (1.007^4t)

47.8819724 = 4t

Answer:

2.4

Step-by-step explanation:

To Find :-

Solution :-

Points are (-2,-2) and (3,10)

Therefore ,

> m = -2-10/ -2-3

> m = -12/-5

> m = 2.4

3-5x=2

or, -5x=-1

or, x= 1/5

The value of x is 1/5 for equation 3 – 5x = 2

Two or more expressions with an Equal sign is called as Equation.

The given equation is 3 – 5x = 2

Three minus five times of x equal to two

We need to solve for x

3 – 5x = 2

Subtract 3 from both sides

3-3-5x=2-3

-5x=-1

Divide both sides by -5

x=-1/-5

x equal to one by five

x=1/5

Hence, the value of x is 1/5 for equation 3 – 5x = 2
