An agricultural scientist collected data to study the relationship between the amount of nitrogen added to a cornfield and the n

umber of
bushels of corn produced. This is the regression line of the data, where y is measured in bushels of corn and x is measured in pounds of
nitrogen.
y = 0.43x + 28.5
What is the meaning of the slope of the regression line?
O A. For every 0.43 pounds of nitrogen added to the field, the amount of corn yielded increases by 28.5 bushels.
OB. For every 1 pound of nitrogen added to the field, the amount of corn yielded increases by 0.43 bushels.
-
OC. For every 1 pound of nitrogen added to the field, the amount of corn yielded increases by 28.5 bushels.
OD. For every 28.5 pounds of nitrogen added to the field, the amount of corn yielded increases by 0.43 bushels.

dusya [7]

Answer:

<u>20%</u> of the garden are tomatoes planted.

Step-by-step explanation:

Given:

Kevin has a rectangular-shaped garden its 15 feet by 12 feet wide.

He plants 36 square feet of tomatoes.

Now, to find the percent of the garden where tomatoes planted.

We need to get the total area of the garden first:

Total area of the garden =  15 feet by 12 feet.

                                         =  15 feet\times 12 feet.

                                         =  180\ square\ feet.

So, getting the area of the garden 180 square feet.

Now, we calculate the percent of the area of garden where tomatoes are planted:

\frac{Area\ of\ tomatoes\ planted}{Total\ area\ of\ garden} \times 100.

=\frac{36\ square\ feet}{180\ square\ feet} \times 100

=\frac{36}{180} \times 100

=\frac{3600}{180}

=20\%.

Therefore, 20% of the garden where are tomatoes planted.

Mercury is the closet planet to the Sun at a distance of 36 million miles. The closest star to the Sun is Proxima Centauri, whic
const2013 [10]
So, if you are trying to convert lightyears to miles, you'll do so with this formula:
mi= (ly)* 5.9e^12, or 59,000,000,000,000. so it would be:
miles=(4.24)(5.9e^12)= roughly 2.5e^13   so Proxima Centauri is   250,000,000,000,000 miles from the Sun
To convert miles to lightyears, you'll just switch them around:
lightyears= (3.6e^6) / (5.9e^12)
Mercury is roughly 0.000006123880 lightyears from the Sun

What are the intercepts of this function f(x)=-8x+4
Sidana [21]

Answer:

Step-by-step explanation:

to find the x-intercept:

Make y=0

0=-8x+4

8x =4

x=4/8

x=1/2

to find y-intercept:

Make x=0

y=-8(0) +4

y=4

Hope this helps!

Chris has a blue coat and a
Tju [1.3M]

Answer: P = 0.125 = 1/8

Step-by-step explanation:

We know that he has a blue coat and a black coat.

If he dresses at random, then the probability of getting the blue coat is equal to the quotient between the number of blue coats (1) and the total number of coats (2).

Then the probability is:

p = 1/2

We also know that he has blue pants and brown pants, the probability of getting at random the blue pants is calculated in the same way than above, then:

q = 1/2

And for the shirt he has a blue shirt and a red one, the probability of randomly selecting the blue one is calculated in the same way than above, then:

k = 1/2

Now, the joint probability (he selects all blue clothes) is equal to the product of the individual probabilities:

P = p*q*k = (1/2)*(1/2)*(1/2) = 1/8 = 0.125

Please answer and explain.
djyliett [7]

Answer:

x = 13

Step-by-step explanation:

The sum of the exterior angles of a 4 sided polygon is 360

139+ 6x+9x+2x = 360

Combine like terms

139+17x=360

Subtract 139 from each side

17x = 360-139

17x = 221

Divide each side by 17

17x/17 = 221/17

x = 13
