What is 21 divided by 2 + 1 times 5 mines 2 to the fourth power?
Sever21 [200]

Answer:

IT is 41.5 heres the steps

Step-by-step explanation:

first step 21 divided by 2 = 10.5

Then you do 10.5 + 1 = 11.5  

then you do 11.5 times 5 =  57.5

Then 2 times 2 times 2 times 2= 16

then 16 - 57.5 = 41.5 is your answer

he temperature at any random location in a kiln used in the manufacture of bricks is normally distributed with a mean of 925 and
Leviafan [203]

Answer:

The proportion of bricks that crack during the firing process is 0.0001 = 0.01%.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions 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.

Mean of 925 and a standard deviation of 60 degrees.

This means that \mu = 925, \sigma = 60

The proportion of bricks that crack during the firing process is closest to

This is 1 subtracted by the pvalue of Z when X = 1150. So

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

Z = \frac{1150 - 925}{60}

Z = 3.75

Z = 3.75 has a pvalue of 0.9999

1 - 0.9999 = 0.0001

The proportion of bricks that crack during the firing process is 0.0001 = 0.01%.

Write a power function representing the verbal statement. (Let k represent the constant of proportionality)
Tatiana [17]

The Power function representing the verbal statement is W = k.n^{1/2}.

<h3>What is the Power function?</h3>

A power function is in the form of f(x) = kxⁿ, where k = all real numbers and n = all real numbers. You can change the way the graph of a power function looks by changing the values of k and n.

When two quantities are proportional, their relationship can be described by the linear equation y = kx, where k is the constant of proportionality.

Now "inversely proportional to the square root" is the same as "proportional to the inverse of the square root."

According to question,

       W α 1/√n

      W = k/√n

      W = k.n^{-1/2}

Thus, the Power function representing the verbal statement is W = k
