Simple!
Okay first plug in the variables given to you.
4(4+8)-4=? Now lets solve.
First, in order to get rid of the paranthesis, multiply 4 by the numbers inside, which in this case are 4 and 8.
That will give us...
16+32-4. Now, remember PEMDAS?
Addition (A) comes before subtraction (S).
So lets add 16 and 32.
Thats 48.
Now 48-4= 44.
44 is our final answer (: so C

Factor to find the zeros of the function defined by the quadratic expression. −7x2 − 91x − 280

Mariulka [41]

There are no zeroes for an expression, only for equations.
Assuming equation to be
<span>−7x^2 − 91x − 280=0
-7(x^2+13x+40)=0
-7(x+8)(x+5)=0
by the zero product properties,
x+8=0 => x=-8
or
x+5=0 => x=-5</span>

19. If the pg", and "terms of an A.P. are a,b, and c respectively. prove that: p(b-c) + (ca) + rſa-b) = 0 50 Approved by Curricu

professor190 [17]

Answer:

Step-by-step explanation:a = m + (p-1)*d

b = m + (q-1)*d

c = m + (r-1)*d

p(b-c) = p*(q-r)*d

q(c-a) = q*(r-p)*d

r(a-b) = r*(p-q)*d

p(b-c)+q(c-a)+r(a-b)

= p*(q-r)*d + q*(r-p)*d +r*(p-q)*d

= (pq-pr+qr-pq+rp-qr)*d

= 0*d = 0

So i prove p(b-c)+q(c-a)+r(a-b)=0 hope this is helpfull

The following data is a randomly selected sample of 20 state populations. find the measures of central tendency. you may use tec

GuDViN [60]

The mean is 6394530.35 and the median is = 3355572.5

The missing data is attached in the answer.

Mean is the average value of the data points , it is determined by dividing the total sum of the data points to the number of data points.

Mean and Median is the measure of the central; tendency of the data.

Mean is given by

Sum of the observations/number of observations

= (741894 + 6931071....)/20

= 6394530.35

2) To find median

The data needs to be arranged in ascending order

Then the median is the middle number of the arranged data

Here the median is = 3355572.5
