Hello there!

-4 + (3) (-8) + 6(-4)

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

You had to used order of operations.

P-Parenthesis

E-Exponents

M-Multiply

D-Divide

A-Add

S-Subtract

First you had to multiply and divide from left to right.

(3)(-8)=-24

-4-24+6(-4)

Then you can multiply and divide from left to right again.

6(-4)=-24

-4-24-24

You can also add and subtract from left to right.

-4-24-24=-52

=-52

Answer⇒⇒⇒⇒=-52

Hope this helps!

Thank you for posting your question at here on Brainly.

Have a great day!

Write 7/8 as a percent to the nearest tenth of the percent
Fiesta28 [93]

7/8 = 87.5%


I'm guessing it is meant to say round to the nearest 10th of a percent

If the question actually says something different comment so i can fix it

British columbia is about 1/11 of the size of canada. Vancouver island is about 1/29 the size of british columbia. What fraction
Irina18 [472]

well, BC is in Canada and is 1/11.

Vancouver is in BC and is 1/29 of BC.

so Vancouver is then 1/29 of 1/11, how much is that?  well, is simply their product.

\bf \cfrac{1}{29}\cdot \cfrac{1}{11}\implies \cfrac{1}{319}

PLS HELP!<br> What is the frequency of the sinusoidal graph?
docker41 [41]

the frequency of the sinusoidal graph is 2 in 2 π interval

Step-by-step explanation:

The frequency of the graphs refers to the number of the cycles, the graph completes in a given fixed interval.  

We already know the formula that  

         P= (1/ F)

Thus, F= (1/ P)

Where F= frequency and P= Period

Period is the horizontal length (x- axis component) of one complete cycle.

Thus, Observing the above graph

We find that the graph completes 1 cycle in π interval and 2 cycles in 2π interval

Thus, the frequency of the sinusoidal graph is 2 in 2 π interval

An engineer travels daily from home tothelaboratory each morning with an average commutetime of 24.6 minutes with a standard dev
charle [14.2K]

Answer:

1.74% probability that the commute takes more than 32 minutes.

Step-by-step explanation:

Problems of normally distributed samples can be solved using 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.

In this problem, we have that:

\mu = 24.6, \sigma = 3.5

a.What is the probability that the commute takes more than 32 minutes?

This is 1 subtracted by the pvalue of Z when X = 32. So:

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

Z = \frac{32 - 24.6}{3.5}

Z = 2.11

Z = 2.11 has a pvalue of 0.9826.

So there is a 1-0.9826 = 0.0174 = 1.74% probability that the commute takes more than 32 minutes.
