Answer:

Common Ratio = 2

Step-by-step explanation:

Emily started with 12 lb at start.

She will double each day

So,

2nd day she will take up weight = 12 * 2 = 24

3rd day she will take up weight = 24 * 2 = 48

and so on

This is a geometric sequence, which is a sequence where each term is found by multiplying the previous term by a constant which is known as the common ratio.

Here, we are multiplying by "2" to get the next term, so we an say the common ratio is "2".

<u>Answer: Common Ratio = 2</u>

3 ( x ) + 55 = 85

Answer To Solving Y:

Let's solve your equation step-by-step.

3x + 55 = 85

Step 1: Subtract 55 from both sides.

3x + 55 − 55 = 85 − 55

3x = 30

Step 2: Divide both sides by 3.

3x / 3 = 30 / 3

x = 10

2 ( y ) - 5 = 95

Answer:

Let's solve your equation step-by-step.

2y − 5 = 95

Step 1: Add 5 to both sides.

2y − 5 + 5 = 95 + 5

2y = 100

Step 2: Divide both sides by 2.

2y / 2 = 100 / 2

y = 50

Which expressions are equivalent to -2.5(1-2n) - 1.5n

Keith_Richards [23]

Answer:

-5n - 4

Step-by-step explanation:

The goal is to simplify this expression.

1. Distribute

-2.5 * 1 = -2.5

-2.5 * 2n = -5n

Now, we have

-2.5 - 5n - 1.5

2. Combine like terms

-2.5 + (-1.5) = -4 (+ * - = - The - cancels out the +)

3. Put it together

-5n - 4

I hope I helped!

A normal distribution has a mean of µ = 100 with σ = 20. if one score is randomly selected from this distribution, what is the p

avanturin [10]

Given: Mean of Normal distribution μ = 100, standard deviation σ =20

We have to find the probability that the score will be less than X=84

P(X < 84)

The z-score for x=84 is

Z = $\frac{x-mean}{standard deviation}$

Z = $\frac{84-100}{20}$

Z = -0.8

We have to find probability that Z < -0.8

Using Z score table to find the probability below z=-0.8 we get

P(Z < -0.8) = 0.2119

Hence the probability that the score will be less than x = 84 is 0.2119
