2 answers:

6 0

Simple...if you want to solve this.....

49-7x=21

Isolate the variable (x)

49-7x=21
-49 -49

-7x=-28

Now, simplify...

$\frac{-7x}{-7} = \frac{-28}{-7} =4$

x=4

Thus, your answer.

Answer:

The value of x = 4 makes the given equation true.

Step-by-step explanation:

Here we have to find what value of x, makes the given equation 49 -7x = 21 true.

To find the value of x, we need to solve for x.

49 - 7x = 21

Step 1: Isolate the variable and constant terms.

Subtract 49 from both sides, we get

-49 + 49 - 7x = 21 - 49

-7x = -28

Step 2: Divide both sides by -7, we get

$\frac{-7x}{-7} = \frac{-28}{-7}$

x = 4

So, the value of x = 4 makes the given equation true.

Check

49 -7x = 21

Plug in x = 4

49 - 7(4) = 21

49 - 28 = 21

21 = 21

Which is true.

hoa [83]

Hello,

To solve, factour out the expression: 9a^4b^4-27a^3b^3+18a^3b^2.

Once factoured out you get the GCF 9a^(3)b^(2)

diamong [38]

Answer:

0.9909 = 99.09% probability that the proportion of flops in a sample of 404 released films would be greater than 4%

Step-by-step explanation:

I am going to use the binomial approximation to the normal to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

$E(X) = np$

The standard deviation of the binomial distribution is:

$\sqrt{V(X)} = \sqrt{np(1-p)}$

Normal probability distribution

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.

When we are approximating a binomial distribution to a normal one, we have that $\mu = E(X)$ , $\sigma = \sqrt{V(X)}$ .
