9 – 2k = 25 what is k

Mathematics

worty [1.4K]4 years ago

Answer:

k = - 8

Step-by-step explanation:

Subtract 9 from both sides to get the constants on one side and the variables on the other

9 - 2k = 25

- 2k = 25 - 9

Simplify

- 2k = 16

Divide by -2 on both sides to isolate the variable, then simplify once more.

- 2k/ -2 = 16/ -2

k = 16/ -2

k = -8

Answer:

      k = -8

Step-by-step explanation:

9 – 2k = 25

   - 2k  = 25 - 9

    -2k = 16

         k = 16 / -2

         k = -8

Look at the angles for all regular polygons. As the number of sides increases, do the measures of the angles increase or decreas
Verdich [7]

Answer:

As the number of sides increases, the measures of the angles increase

see the explanation

Step-by-step explanation:

we know that

The measure of the interior angle in a regular polygon is equal to

x=\frac{(n-2)}{n}(180^o)

where

n is the number of sides of the regular polygon

x is the measure of the interior angle in a regular polygon

we have that

<u><em>Examples</em></u>

<em>A triangle</em>

n=3 sides

x=\frac{(3-2)}{3}(180^o)=60^o

<em>A square</em>

n=4 sides

x=\frac{(4-2)}{4}(180^o)=90^o

<em>A pentagon</em>

n=5 sides

x=\frac{(5-2)}{5}(180^o)=108^o

<em>A hexagon</em>

n=6 sides

x=\frac{(6-2)}{6}(180^o)=120^o

so

n ----> 3,4,5,6...

x ----> 60°,90°,108°,120°,...

As the number of sides increases, the measures of the angles increase

The pattern is x=\frac{(n-2)}{n}(180^o)

Can somebody help me find the mean,median, and mode
andrey2020 [161]

Answer:

so for the mean u add all the numbers on there and then divide it by 5 since there are 5 numbers on there so 78+84+100+78+81=421 now we divide 421 by 5 so 421÷5= 84!

now the median would be 100? and the mode is 78 since 78 is the number that showed the most!

The cable company takes an SRS (simple random sample) of 250 of the approximately 15,000 households who subscribe to them. They
bazaltina [42]

Answer:

The mean of the sampling distribution of p is 0.75

The standard deviation of the sampling distribution of p is 0.0274

Step-by-step explanation:

According to the given data 75% of the sampled households watch sports on television at least once a month therefore the mean of the sampling distribution of p is 0.75.

In order to calculate the standard deviation of the sampling distribution of p we would have to use the following formula as follows:

Standard deviation = √ [ p ( 1 - p) / n ]

= √[ 0.75 * ( 1 - 0.75) / 250]

= 0.0274

The standard deviation of the sampling distribution of p is 0.0274.
