162=470m+b and 183=540m+b.
183-162=(540-470)m, 21=70m so m=0.30.
162=470×0.30+b=141+b, b=162-141=21
Therefore y=0.30m+21.

Solve for X.<br> 4(2x + 5) + 2x + 3 = -11

S_A_V [24]

We can begin by rewriting the problem:

4(2x + 5) + 2x + 3 = -11

Let’s solve in steps.

1. Distribute

8x + 20 + 2x + 3 = -11

2. Combine like terms

10x + 23 = -11

3. Subtract 23 from both sides

10x + (23 - 23) = -11 - 23

10x = -34

4. Divide both sides by 10

10 / 10 = 1 (or x)

-34 / 10 = -3.4

Therefore, x = -3.4.

How do i find the difference between two different times e.g 13:40 and 17:15

AVprozaik [17]

You find their difference, of course!

E.g. 17:15 - 13:40 = 3:35/ 3 hrs 35 min.

Just remember that a full hour (1:00) is 60 minutes (0:60). You would never write anything as 0:60, though! Anything over 0:59 becomes 1:00 + the remaining number of minutes.

Hope this wasn't too confusing! Practice makes it easier to handle and understand, so try it out! Hope this helps :)

Answer:

0.82% probability that the average time it takes to complete both homework assignments is greater than 82 minutes

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Math homework:

$\mu_M = 30, \sigma_M = 3$

Arts homework:

$\mu_A = 40, \sigma_A = 4$

What is the probability that the average time it takes to complete both homework assignments is greater than 82 minutes?

Here, we have a sum of normal variables. The mean will be the sum of the means, while the standard deviation is the square root of the sum of the variances. So

$\mu = \mu_M + \mu_A = 30 + 40 = 70$
