FIVE 18

Answer:

180mm^2

Step-by-step explanation:

CB = 15^2 + 6^2 = 261, the square root of 261 is ~16mm

CB is 16mm

the area of the triangle is A=ab/2

A=45mm^2

Now you need to find the area of the rectangle

A=l×w

A= 15×9= 135mm^2

now add both areas

(135+45)mm^2=180mm^2

180mm^2Answer:

A. Mean deviation is the range of the mean essentially.

Answer:

6584.22

Step-by-step explanation:

used a calculator (ti-84 plus tx instruments)

Answer:

1. 2

2. 30

Step-by-step explanation:

1. The weird circle looking thing essentially means you're putting p(x) inside of q(x). This means you take the x in q(x) and replacing with the entire p(x)

so q(x) = -3x - 4

(q °p)(x) = -3 (-2x+4) -4  sorry I can't find the actual circle thing symbol

now distribute to get the simplified equation:

= 6x -12 -4

= 6x - 16

because you're doing (q - p )(3), you would plug 3 for x into the new equation

6(3) - 16 = 2

and thats you're answer for the first one

for the second one its the other way around, so you're putting all of q(x) into p(x)

take p(x) : -2x+4

and now replace the x with the entire q(x)

so (p - q)(x) = -2 (-3x-4) +4

simplify: = 6x+8+4 = 6x+12

so now since we're doing (p-q)(3), we need to plug in 3 for x in the new equation

= 6(3)+12 = 30

lmk if those were wrong or if my explanation was unclear, there's another way I can explain it even though its the same process :)

Answer:

1a) $11,610

1b) $967.5

2) 15.826

3) 20%

Step-by-step explanation:

1a)

27/100 = .27

.27(43,000) = $11,610 a year

1b) $11,610 / 12 months = $967.5 a month

2)

19.3/100 = .193

.193(82) = 15.826 hits

3) 16/80 = .2

.2(100) = 20%

Answer:

Volume: 12 cubic inches

Step-by-step explanation:

Volume is basically height times width times base

Answer:the third one

Step-by-step explanation:

Answer:

it is the third one(200)

Step-by-step explanation:

you have to do base times height, the base is 20 and the height is 10. So you do 20x10 and you get 200. Hope this helped!

Answer:

c

Step-by-step explanation:

The solution is : 6 feet describes the center, and 9 feet describes the spread

In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

here, we have,

The center of a data set is mostly considered as the median or the mean

Here mean is 6 (given). And median is also 6.

As 6 is exactly at the middle of the data set. (When arranged in ascending order)

Now, one of the way of calculating the spread is calculating the range, here it's given that the range is 9.

Therefore, 6 feet describes the center, and 9 feet describes the spread is correct.

#SPJ2

Answer:

y = -1/2x -7

Step-by-step explanation:

. The slope of the line (rise over run) goes down so it's negative and it you go down (bc it's negative slope) 1 and go over 2 so it would be -1/2

. B stands for the y intercept so it would be -7 because the line goes through -7 on the vertical line.
