Product of 8 and the sum of 4 and a number:

sum of 4 and a number: (4 + n)

Product of 8

8 x (4 + n) is 112

8 x (4 + n) = 112

Distribute

32 + 8n = 112

Subtratc

8n = 80

Divide by 8

n = 10

The number is 10, and next time please put options because it says "Which equation could be used to solve for the number?" Thanks! :)

Answer:

$x=10$

$8(4+x) = 112$

Step-by-step explanation:

the product of 8 and the sum of 4 and a number is 112

LEt x be the unknown number

the sum of 4 and a number

Sum means addition, so we add 4 and x

$4+x$

product of 8 and sum 4+x

product means multiplication

$8(4+x)$

8(4+x) is equal to 112

$8(4+x) = 112$ is the equation used to solve for the number

We solve for x

$32 + 8x = 112$

Subtract 32 on both sides

$8x=80$

divide by 8 on both sides

$x=10$

If Q is the midpoint of pr, find the coordinates of r if p(11,-2) and q(4,3) look

Vlada [557]

R is (-3,8)
to get from p’ to q’, you subtract 7 from the x’ value, and add 5 to the y’ value. so you do the same to get from q’ to r’

The 3rd term in a geometric sequence is 40. The 5th term is 10. What are the possible values of the 4th term?

marishachu [46]

To answer, we let x be the 4th term. We use the concept of geometric mean in order to answer this question. The ratio of the fourth term and the third term is equal to the ratio of the fifth term and the fourth term. That is,
x/40 = 10/x
The values of x from the equation are 20 and -20.

What do the following two equations represent?

klio [65]

Answer:

perpendicular lines

Step-by-step explanation:

when the two equation are written in slope intercept form:

y = -4x -7

y = 1/4x -2

the slopes are opposite reciprocals which means they are perpendicular

A fair die is rolled 10 times. Find the expected value of:a) the sum of the numbers in the ten rolls;b) the number of multiples

velikii [3]

Answer:

a) 3.5

b) 3.33

c) $6 - 6\left(\begin{array}{ccc}5\\6\end{array}\right)^{10}$

Step-by-step explanation:

As given,

A fair die is rolled 10 times

Expected value of Sum of the number in 10 rolls = $\frac{1}{6}(1+2+3+4+5+6) = \frac{21}{6}$

= 3.5

∴ we get

Expected value of Sum of the number in 10 rolls = 3.5

Ley Y : number of multiples of 3

Y be Binomial

Y - B(n = 10, p = $\frac{2}{6}$ )

Now,

Expected value = E(Y) = np = 10× $\frac{2}{6}$ = 3.33

Let m = total number of faces in a die

⇒m = 6

As die is roll 10 times

⇒n = 10

Now,

Let Y = number of different faces appears

Now,

Expected value, E(Y) = m - m $\left(\begin{array}{ccc}m-1\\m\end{array}\right)^{n}$

= $6 - 6\left(\begin{array}{ccc}6-1\\6\end{array}\right)^{10} = 6 - 6\left(\begin{array}{ccc}5\\6\end{array}\right)^{10}$
