In three math tests, you have scored 91,95 and 88 points. You are about to take your next test. Suppose you want to have an average score of at least 90 points after all four tests. Explain a method you could use to find the score you must receive in order to average at least 90 points. The find the least score.

Answers

first you add up all the numbers then divide them by 3 then you get your answer:
91+95=186 186+88=274
274÷3=91.333333333and so on
next you add 90 to 27540
274+90=364
and since there are 4 tests you divide 364 by 4
364÷4=91
Answer-91

Answer:


You have to add up all the numbers then divide them by 3 and you will get your answer:

91+95=186 186+88=274

274÷3=91.333333333 etc.

then you add 90 to 27540

274+90=364

and because there are 4 tests you divide 364 by 4

364÷4=91

Your Answer-91

Factor the binomial or identify it as prime.2z4 – 2

A. 2(z2 + 1)(z2 – 1)
B. 2(z2 + 1)(z – 1)(z + 1)
C. Prime
D. 2(z2 + 1)2

Answers

Answer:

The correct answer is B,

Step-by-step explanation:

Since the higher value of z's power, is 4, an even number, and the second number is negative, we can think that this binomial is made of a difference of squares, so that is what we are going to factorize.

First, extract the common number (if any), the number 2, we have now>

2*(z^(4)-1)

This is convenient since "1" is a wonderful number that has this feature>1^(n)= 1 No matters what n's value is,

so the first equation 2*(z^(4)-1) can be written as (2*(z^(4)-1)=2*((z^(2))^(2)-1^(2))=2*(z^(2)-1)*(z^(2)+1)

The later termn, can also be factorized, using the same as befre.

(z^(2)-1)=(z-1)*(z+1)

Remember that z^(4)=(z^(2))^(2)

A restaurant offers hamburgers with one, two, or three patties. Let X represent the number of patties a randomly chosen customer orders on their hamburger. Based on previous data, here's the probability distribution of X along with summary statistics:X=# of patties 1 2 3
P(X) 0.40 0.50 0.10
Mean: μX​=1.7
Standard deviation: σX​≈0.67
The total price of each burger is set at $2 per patty. Let T represent the total price a randomly chosen customer pays for their burger. Find the mean of T

Answers

Answer:

The mean price a randomly chosen customer pays for her or his burger is US$ 3.40

Step-by-step explanation:

Let's find out the mean of T (total price a randomly chosen customer pays for their burger), this way:

Mean of T = 0.4 * $ 2 + 0.5 * $ 4 + 0.1 * $ 6

Mean of T = 0.8 + 2 + 0.6

Mean of T = US$ 3.40

The mean price a randomly chosen customer pays for her or his burger is US$ 3.40
