For any approximately normal distribution, how can we find the relative frequency of the scores?

1 answer:

We can, transform the raw scores to z-scores and use the standard normal curve to find the relative frequency of the scores.

I hope this helped!

Bob took his family out to lunch. He bought 3 hot dogs and 2 hamburgers for $11. If the guy in front of him bought 2 hot dogs an

Answer:

Hotdog: $1.50

Hamburger: $3.25

Step-by-step explanation:

You write down the 2 equations based off of the information as I did:

Let x = cost of a hotdog

Let y = cost of a hamburger

and so:

3x + 2y = 11

2x + 4y = 16

Now, we need to find x and y:

We will make both equations equal to y to compare them to each other.

2y = 11 - 3x

y = 5.5 - 1.5x

4y = 16 - 2x

y = 4 - 0.5x

4 - 0.5x = 5.5 - 1.5x

x = $1.5

Now plugging in x into the equation:

2(1.5) + 4y = 16

3 + 4y = 16

4y = 13

y = $3.25

And so hotdog = $1.5 and hamburger = $3.25

Answer:

x = 1 1/4

Step-by-step explanation:

6x - 1 = -2x + 9

Move the x to one side and the numbers to the other side:

8x = 10

Simplify:

x = 10/8 = 5/4 = 1 1/4
