8 0

Y = a number
"is" means "equal to"

Equation:
Y - 8 = 94

Solving for Y:
Y - 8 = 94
Add 8 to both sides
Y = 102

Answer: Y = 102

Hope this helps!!

What is the remainder in the synthetic division problem below?

Naddik [55]

Answer:

The remainder is 25 ⇒ answer (C)

Step-by-step explanation:

* The remainder will be the last number in the calculation

* From the picture the dividend is 3x³ + x² + 2x - 7 and x - 2 is the divisor

- In the synthetic calculation we use the coefficient of the dividend with the value of x when the divisor = 0

- From the picture the divisor is x - 2, when x - 2 = 0, then x = 2

∵ The coefficient of the dividend are 3 , 1 , 2 , -7

Step 1 : Write down the coefficients of the dividend , put x = 2 at the left

2 3 1 2 -7

_____________

Step 2 : Bring down the first coefficient to the bottom row.

2 3 1 2 -7

____________

Step 3 : Multiply it by 2, and carry the result into the next column.

2 3 1 2 -7

___6_________

Step 4 : Add down the column

2 3 1 2 -7

___6_________

3 7

Step 5 : Multiply it by 2, and carry the result into the next column

2 3 1 2 -7

___6_14_______

3 7

Step 6 : Add down the column

2 3 1 2 -7

___6_14_______

3 7 16

Step 7 : Multiply it by 2, and carry the result into the next column

2 3 1 2 -7

___6_14_32______

3 7 16

Step 8 : Add down the column

2 3 1 2 -7

___6_14_32______

3 7 16 25

∴ The quotient is (3x² + 7x + 16) and the remainder is 25

What is the coefficient of the variable in the expression 6-4x-8x+2

Daniel [21]

I think the trick is to add the two middle terms together. (And the 2 end terms).

8 - 12x

The variable is x. The coefficient is - 12.

8 is a constant.

The coefficient always goes with a variable.

3x^2 + 2x + 5

Nothing can be combined. The leading coefficient is 3 (which goes with the greatest power of the variable x^2 in this case) and the other coefficient is 2. 5 is a constant.

Suppose that a company selects two people who work independently inspecting two-by-four timbers. Their job is to identify low-qu

Stella [2.4K]

Answer:

Step-by-step explanation:

Given

Probability that an inspector doe not identify low-quality timber=0.20

(a)Probability that both inspector do not identify a low quality timber

$P=0.2\times 0.2=0.04$

(b)Let n be the no of inspector

Probability should be less than 1%=0.01

so $\left ( 0.2\right )^n$

Taking $\ln$ both sides

$x>\frac{\ln 0.01}{\ln 0.2}$

x>2.861

thus minimum value of x is 3

(c)From part b it is clear that minimum 3 officer are required to to keep the low quality timber below 1%

on an average 2 officer are not sufficient to identify 4 low quality timber out of 100
