<h3>Answer:  262,785</h3>

Note: you may need to delete the comma

============================================================

Explanation:

The info "5 months" is never used to compute the mean. We could easily replace it with "6 months" or "7 months" or any stretch of time, and still get the same answer. So we'll ignore this value.

What we'll do is add up the 21 items given to us, and then divide by 21.

Because there are so many values, and it's easy to get lost, I'm going to add up across the rows

  • Row One: 256,229+253,657+218,747+246,163+235,626+288,694 = 1,499,116
  • Row Two: 316,265+196,721+319,620+285,077+215,152+253,291 = 1,586,126
  • Row Three: 315,011+199,901+265,443+291,806+303,556+215,359 = 159,1076
  • Row Four: 258,554+293,658+289,935 = 842,147

Those subtotals then add up to this

1,499,116+1,586,126+1,591,076+842,147 = 5,518,465

This is the same as adding up all 21 values.

Finally, we divide that sum over 21 as there are 21 values in this list

(5,518,465)/21 = 262,784.047619048

That value then rounds up to 262,785

If your teacher just wanted things to the nearest whole number (without rounding up), then the answer would be 262,784

Side note: using a spreadsheet program would probably be the most efficient/fastest method for this type of problem.

I need to know how to do these asap!!
ludmilkaskok [199]

Answer:


Step-by-step explanation:

y =4/3 x+4

slope intercept form

y = mx+b

the y intercept is 4  (0,4)

and the slope is 4/3  which is change in y over change in x

we go up 4 to the right 3

we can rewrite the slope as -4/-3

so we can go down 4 and to the left 3

this would be point (-3,0)


we have 2 points marked, now draw a line throught them

1/(x+4)(x-2)(x-5) excluded values
UNO [17]

Answer:

see explanation

Step-by-step explanation:

The excluded values are any values of x that make the function undefined

Given

\frac{1}{(x+4)(x-2)(x-5)}

The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the values that x cannot be.

(x + 4)(x - 2)(x - 5) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 2 = 0 ⇒ x = 2

x - 5 = 0 ⇒ x = 5

x = - 4, x = 2, x = 5 are the excluded values

Find the base of a parallelogram with a slant height of 7cm and an perimeter of 63 cm2
vlada-n [284]

Base of parallelogram b = 24.5 cm

Step-by-step explanation:

We are given:

Perimeter =P= 63 cm^2

Slant Height =a= 7 cm

Base of Parallelogram =b= ?

The formula used is:

Perimeter = 2(a+b)

where a is height and b is base

Putting values:

Perimeter = 2(a+b)\\63=2(7+b)\\63=14+2b\\2b=63-14\\2b=49\\b=\frac{49}{2}\\b=24.5

So, Base of parallelogram b = 24.5 cm

A principal of $2600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 8 years?
almond37 [142]
To add 7.5% to a number you simply multiply the number by 1.075. To compound that amount year after year, you raise 1.075 to an exponent that corresponds to the number of years.  2600*(1.075^8)=<span>4637.04234646</span>

3y + 2x - 10 = 0 <br>find m​
Hitman42 [59]

Step-by-step explanation:

3y + 2x - 10 = 0

in standard form

2x + 3y -10=0

||

as (ax + by - c = 0)

m = -a/b

= -2/3

or

3y + 2x - 10 = 0

make y subject

y = -2/3x + 10/3
