Answer:

2x +3

Step-by-step explanation:

the product of two and a number means the total of 2 and a number we don't know. We know this because product means multiply.

Then it says 3 more. Using PEMDAS we know that multiplication comes BEFORE addition. So we multiply first then add the 3. So the formula would be

2x + 3

Answer:

2x+3

Step-by-step explanation:

Three more than something means adding, so we can just add 3.

Then, having a product of something means the two numbers were multiplied together, so we can write it as 2x.

Our final equation is 2x+3

Hope this helps!

Answer:

s\geq 23

Step-by-step explanation:

We are given that a student needs to make a square cardboard piece.

Perimeter of cardboard  should be equal to atleast 92 inches

We have to find that which shows reasonable domain for f(s)

Let s be the side of square cardboard

We know that perimeter of square =f(s=)4\times side

Then, perimeter of  cardboard=4s

4s\geq 92

Dividing by 4 on both sides

s\geq 23

Hence, the domain of function[23,\infty)

Therefore, option d is true.

Answer:d: s\geq 23

on a standardized exam the scores are normally distributed with a mean of 70 and a standard deviation of 20. find the z of a per
KIM [24]

The z-score of a person who scored 128 on the exam is equal to 2.9

<h3>What is a z-score?</h3>

A z-score is also referred to as a z-value or standard score and it can be defined as a measure of the distance between a raw score and the mean, when standard deviation units are used.

Mathematically, the z-score of a given sample score in a normal distribution can be calculated by using this formula:

z=\frac{x\;-\;u}{\sigma}

Where:

  • x represents the sample score.
  • u represents the mean score.
  • σ represents the standard deviation.

Substituting the given parameters into the formula, we have;

Z-score, z = (128 - 70)/(20)

Z-score, z = 58/20

Z-score, z = 2.9
