Answer:

X=___ or x=8 or one of my other answers in the explanation! I hope this helped!

Step-by-step explanation:

it must be 4 because 4 goes on the side by +4 and its x+4 then the other side of the shape is 8 so that meaning x is 4 then 2x+1 is 2 times X + 1 so 2 times 4... 2,4,6,8 or 4+4=8 so then 2 times + 1 is 8 + 1 so 8+1=9 so 2x+1 might also be 12 because its on the other side of the problem/ shape so you use all that you have so you could maybe plus the other side not the problem side for making it a and c and stuff but also 8+12 so 8+12=20 then x might be 20 but you answer meaning X is 8. X=8 Brainliest? i tried really hard! I am not even near this grade whatever grade this is... Plz! Thanks! Thank you! Have a great day or week or weekend! i answer a lot of questions and help 114 people or something or more! Plz put 5 stars, a heart, and brainliest i would really appreciate that thank you!

Can anyone please help me?

Yanka [14]

Answer:

B.

Step-by-step explanation:

Parentheses mean multiplication in this case. So it would be 2 x -3 OR -3 + -3. When multiplying a negative and a positive the answer will ALWAYS be negative. So you would move to the left on a number line.

A cookie company packages its cookies in rectangular prism boxes designed with square bases that have both a length and width of

maw [93]

Answer:

h³- 8h² + 16h

Step-by-step explanation:

The problem tells us that the length and width of these boxes are both 4 inches less than the height of the box.

So if we name h the height of the box, the width of the box would be h - 4 and the height of the box would be h - 4.

Now, the volume of a rectangular prism is given by V = height x width x length

So, considering the values we have in this problem we get:

V= height x width x volume

V = h (h-4)(h-4)

V= h(h-4)²

V= h (h²-8h + 16)

V = h³- 8h² + 16h

Therefore, the polynomial representing the volume of this box in terms of the height is h³- 8h² + 16h

The one-time fling! Have you ever purchased an article of clothing (dress, sports jacket, etc.), worn the item once to a party,

rjkz [21]

Answer:

a) 0.2725

b) 0.7275

c) 0.8948

Step-by-step explanation:

This is a binomial distribution probability problem. The formula is:

$P(x)=\frac{n!}{(n-x)!x!}p^{x}q^{n-x}$

Where

n is the number of trials [here we are taking 8 person, so n = 8]

x is what we are looking for [in the problem]

p is the probability of success [ 15%, so p = 0.15

q is the probability of failure [q = 1-p = 0.85]

Now,

a)

We are looking for "no one" did fling, so x = 0

Let's put into formula and find out the probability:

$P(x=0)=\frac{8!}{(8-0)!0!}(0.15)^{0}(0.85)^{8}\\P(x=0)=0.2725$

So, the probability that no one has done a one-time fling is 0.2725

b)

Atleast 1 person means P(x ≥ 1).

This can be found by:

P(x ≥ 1) = 1 - P(x=0) = 1 - 0.2725 = 0.7275

THus, Probability that at least one person has done a one-time fling is 0.7275

c)

No more than 2 people means P (x≤2).

This is essentially

P ( x ≤ 2 ) = P(x=0) + P(x=1) + P(x=2)

P ( x = 0 ) is found in part (a), which is 0.2725

P (x = 1 ) and P(x=2) can be found using formula:

$P(x=1)=\frac{8!}{(8-1)!1!}(0.15)^{1}(0.85)^{7}\\P(x=1)=0.3847$

and

$P(x=2)=\frac{8!}{(8-2)!2!}(0.15)^{2}(0.85)^{6}\\P(x=2)=0.2376$

Thus,

P ( x ≤ 2 ) = P(x=0) + P(x=1) + P(x=2) = 0.2725 + 0.3847 + 0.2376 = 0.8948
