A chef prepared five chocolate tortes for a dinner party. The guests consumed 2 5/16 tortes. How many
Alenkinab [10]
If you would like to know how many tortes are left, you can calculate this using the following steps:

five chocolate tortes - 2 5/16 tortes = 5 - 2 5/16 = 5 - 37/16 =  80/16 - 37/16 = 43/16 = 2 11/16

The correct result would be D. 2 11/16.

What is the best first step in solving the equation 3x2 + 8x = -5?
Rashid [163]
I would assume it would be dividing both sides by three although if someone were to actually solve this I would say multiply 2 and 3 together first.

Hope this helps :)

A population has a mean µ = 6 and ∑x = 48. How many scores are in the population?
maks197457 [2]

Answer:

8

Step-by-step explanation:

Recall the formula for the population mean of a data set:

\mu=\frac{\sum x}{N}

We already know that μ is 6 and the sum is 48. Substitute:

6=\frac{48}{N}

Divide both sides by 48:

\frac{1}{8}=\frac{1}{N}

Reciprocal of both sides:

N=8

Thus, there are 8 scores in the population size.

And we're done!
