Oh my goodness . . .

What do you get when you multiply a number by itself ?
Do you get the square of the number ?

And what do you get when you square the square root of a number ?
Is it the number inside the square root ?

For just a second, let's take the quantity (4t - 3) and call it ' Q '.
Then the problem is to multiply
                                                   √Q times √Q .
Isn't that just ' Q ' ?

And is this enough help ?

Answer:

Step-by-step explanation:

          Steps                                     Property

x(1 + y) + y(2 + x)                           Given

x + xy + 2y + xy                            Distributive property

x + xy + xy + 2y                            Commutative property of addition

                                                     [a + b = b + a]

x + (xy + xy) + 2y                           Associative property of addition

                                                      [(a + b) + c = a + (b + c)]

x + 2xy + 2y                                  Combine like terms

It has been observed that electrical connectors manufactured by Jolt Electrical Supply Company last an average of 18.2 months an
Juli2301 [7.4K]

Answer:

340

Step-by-step explanation:

The first step is finding the percentage of those who fail within 19 months.

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 = 18.2, \sigma = 1.7

The proportion is the pvalue of Z when X = 19. So

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

Z = \frac{19 - 18.2}{1.7}

Z = 0.47

Z = 0.47 has a pvalue of 0.6808.

Jolt is expected to replace 0.6808 of the connectors sold. Out of 500, that is, on average, 0.6808*500 = 340.

Jolt expects to replace, on average, 340 of the connectors sold.
