Answer:

The mean is: 85

Step-by-step explanation:

First you need to add everything up :

1 * 2 = 2

2 * 1 = 2

3 * 3 = 9

4 * 5 = 20

5 * 4 = 20

6 * 3 = 18

7 * 2 = 14

(I multiplyed them all first because i was fast than doing 4+4+4+4+4 because its the same as 4 * 5)

then add them all up 2+2+9+20+20+18+14=85

Answer:

The median is: 4

Step-by-step explanation:

Get the data in NUMERICAL ORDER (smallest to largest), then eliminate the extremes until we're at the middle. (basically chopping off the end till you get to the middle) Therfore The answer would be 4.

Answer:

The mode would be: 4

Step-by-step explanation:

The mode is Get the data in NUMERICAL ORDER, and see which value is the most frequent (we can have more than one mode).

Answer:

25%

Step-by-step explanation:

firs you do 5 divided by 20 because there are 20 x's. this will = 0.25

0.25 = 25%

I hope I get brainiest. Sorry for taking forever. Have a nice day!

Answer the question above

Vera_Pavlovna [14]

Answer:

$tan\:\left(\frac{5\pi }{6}\right)=tan\left(-\frac{\pi }{6}\right)$

Option A is correct.

Step-by-step explanation:

We need to find equivalent of $tan\:\left(\frac{5\pi }{6}\right)$

First we solve $tan\:\left(\frac{5\pi }{6}\right)$

We get $-\frac{1}{\sqrt{3} }$

Now checking all the options.

Option A: $tan\:(-\frac{\pi}{6} )$

Solving $tan\left(-\frac{\pi }{6}\right)\: we\: get\: \mathbf{ -\frac{1}{\sqrt{3} }}$

Option B: $tan\left(\frac{7\pi }{6}\right)$

Solving $tan\left(\frac{7\pi }{6}\right)\: we\: get\: \mathbf{\frac{1}{\sqrt{3} }}$

Option C: $cot\left(\frac{5\pi }{6}\right)$

Solving $cot\left(\frac{5\pi }{6}\right)\:we\:get\:\mathbf{-\sqrt{3} }$

Option D : $tan\left(-\frac{5\pi }{6}\right)$

Solving $tan\left(-\frac{5\pi }{6}\right) \:we\:get:\mathbf{\frac{1}{\sqrt{3} } }$

So, looking at the options, only Option A has the same result as given question

So, $tan\:\left(\frac{5\pi }{6}\right)=tan\left(-\frac{\pi }{6}\right)$

Option A is correct.

The function c(s) gives the number of corn ears a farmer can harvest by planting s number of seeds. Each statement below can be

aleksandr82 [10.1K]

1. c(800)=600 has same meaning as after planting 800 seeds, there will be 600 corn ears.

2. c(200) = e has the same meaning as there will be e corn ears when 200 seeds are planted.

3. c(s) = 900 has same meaning as the number of corn ears is 900 when s seeds are planted.

Step-by-step explanation:

According to given statement;

c(s) = Number of corn ears

s = Number of seeds

1. After planting 800 seeds, there will be 600 corn ears.

Here,

Number of seeds = s = 800

Number of corn ears = 600

Putting in function

c(800) = 600

c(800)=600 has same meaning as after planting 800 seeds, there will be 600 corn ears.

2. There will be e corn ears, when 200 seeds are planted.

Number of seeds = s = 200

Number of corn ears = e

Putting in function

c(200) = e

c(200) = e has the same meaning as there will be e corn ears when 200 seeds are planted.

3. The number of corn ears is 900 when s seeds are planted.

Number of seeds = s

Number of corn ears = 900

Putting in function

c(s) = 900

c(s) = 900 has same meaning as the number of corn ears is 900 when s seeds are planted.
