What is the value of C?<br>14 = -2C - 6 – 3C <br>

icang [17]

Answer:

C = -4

Step-by-step explanation:

First, combine like terms (terms with the same amount of variables):

14 = -2C - 3C - 6

14 = (-2C - 3C) - 6

14 = (-5C) - 6

Isolate the variable, C. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and equals:

Parenthesis

Exponents & Roots

Multiplication

Division

Addition

Subtraction.

First, add 6 to both sides:

14 (+6) = -5C - 6 (+6)

14 + 6 = -5C

-5C = 20

Next, divide -5 from both sides:

(-5C)/-5 = (20)/-5

C = 20/-5

C = -4

-4 is your value for C.

Grandma makes chocolate chip cookies in batch of 100, and you choose one cookie at random. How many chips should she put in the

elena55 [62]

Answer:

391 chips

Step-by-step explanation:

This is a Poisson distribution problem with the formula;

P(X = k) = (e^(-λ) × λ^(k))/k!

Let n be the number of chips she puts in the dough.

Since she makes chocolate chip cookies in batch of 100, then the mean number of chips is n/100.

So, λ = n/100

Now, we want to find how many chips should she put in the dough so that the probability your cookie contains no chip is 0.02.

Thus;

P(X = 0) = (e^(-λ) × λ^(0))/0! = 0.02

This gives;

e^(-λ) = 0.02

Putting λ = n/100, we have;

e^(-n/100) = 0.02

-n/100 = In 0.02

-n/100 = -3.912

n = -100 × -3.912

n ≈ 391 chips

On a coordinate plane, a square and a point are shown. The square has points R prime (negative 8, 1), S prime (negative 4, 1), T

VladimirAG [237]

Answer:

(–1, –6)

Step-by-step explanation:

Given that S(3, –5) was translated to S'(–4, 1), the transformation rule is (x-7, y+6). Then, the coordinates of square RSTU are:

R'(–8, 1) -> (-8+7, 1-6) -> R(-1, -5)

S'(–4, 1) -> (-4+7, 1-6) -> S(3, -5)

T'(–4, –3) -> (-4+7, -3-6) -> T(3, -9)

U'(–8, –3) -> (-8+7, -3-6) -> U(-1, -9)

The point (–1, –6) lies on the segment RU
