Answer:

Step-by-step explanation:

The distributive property is simple. When there are numbers inside the parenthesis and a number outside of it like in the equation, you multiply all of the numbers inside the parenthesis by the outside number.

3 ( 14 - 5 )

3 * 14 = 42

3 * -5 = -15

After this, you take the remaining numbers and use the method PEMDAS to solve the equation.

42 - 15 = 27

Your answer is 27, hope this helps :)

EASY MATH THAT I DON,T GET PLZ HELP QUICKLY<br>

jolli1 [7]

Answer:

Terms: 4

Degree: 3

Leading coeff: 7

Step-by-step explanation:

a term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs, or sometimes by division. 7x³+5x²-3x+1 would have 4 terms: 7x³, 5x², -3x, and 1

You already have the degree which is the highest power in a polynomial

The leading coefficent is the coefficient in the term with the highest power, in this case being 7.

hope this helps!

Calculate the loss on selling 50 shares of stock originally bought at 133/4 and sold at 12. A. $687.50 B. $87.50 C. $600.00 D. $

lianna [129]

Answer:

The loss would be 1062.50

Step-by-step explanation:

To find this, first convert the purchase price into a decimal.

133/4 = 33.25

Now multiply that my the number of shares bought.

33.25 * 50 = 1662.50

This is the amount that was spent. Now to find the sale price, multiply the number of shares by the new price.

50 * 12 = 600

And to find the total loss, subtract the amount of the purchase price from the sale price.

600 - 1662.50 = -1062.50

For a particular diamond mine, 81% of the diamonds fail to qualify as "gemstone grade". A random sample of 92 diamonds is analyz

Fed [463]

Answer:

68.79% probability that more than 79% of the sample diamonds fail to qualify as gemstone grade

Step-by-step explanation:

We 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 $\mu = E(X)$ , $\sigma = \sqrt{V(X)}$ .
