Find the product.<br> 3cd^2(6cd + 14cd^2)

OLEGan [10]

Answer:

A) The number line goes from negative 8 to positive 8. At 0, there is an open circle. The number line is shaded to the left of 0 and on the left end of the shaded line there is a left-facing arrow.

Step-by-step explanation:

Given inequality: x < 0

open circle: < or >

filled circle: ≤ or ≥

Therefore, for x < 0 there will be an open circle at 0.

< means less than, so the number line will be shaded to the left of 0 and there will be a left-facing arrow on the end of the shaded line.

Several shapes are cut out of a piece of cardboard. Two squares of length x, five rectangles of length x and width y and two cir

forsale [732]

The correct question in the attached figure

step 1
calculate the different volumes
a) Volume of prism square base=x*x*y=x²*y
b) Volume of the cylinder=π*(z²)*y

the combined volume of the two figures=[x²*y]+[π*z²*y]

the answer is [y*x²]+[π*y*z²]

Last Saturday,the MoviePlex theater sold 1,456 tickets.The theater sold 6 times as many regular price tickets as it sold discoun

Andrews [41]

Earl is incorrect

let x be the number of discount tickets sold

then the number of regular tickets sold is 6x

the total tickets sold is 1456, thus

x + 6x = 1456

7x = 1456 ( divide both sides by 7 )

x = 208

number of discount tickets sold = 208

$\frac{1456}{6}$ ≠ 208

but $\frac{1456}{7}$ = 208

Earl is incorrect , dividing by 7 gives the amount sold

Suppose that you and a friend are playing cards and you decide to make a friendly wager. The bet is that you will draw two cards

ehidna [41]

The amount of winning is more than amount of loosing. Then the amount of winning will be $3738.

<h3>How to find that a given condition can be modelled by binomial distribution?</h3>

Binomial distributions consist of n independent Bernoulli trials.

The expected value will be

E(X) = np

Suppose that you and a friend are playing cards, and you decide to make a friendly wager.

The bet is that you will draw two cards without replacement from a standard deck.

If both cards are spades, your friend will pay you $39.

Otherwise, you have to pay your friend $5.

If this same bet is made 623 times.

The maximum amount of winning will be

E(win) = np

We have

p = 0.25

n = 623

Then we have

E(win) = 0.25 × 623

E(win) = 155.75

Then the winning amount will be

WA = 155.75 × 39

WA = $6074.25

The maximum amount of loosing will be

E(loose) = np

We have

p = 0.75

n = 623

Then we have

E(loose) = 0.75 × 623

E(loose) = 467.25

Then the loosing amount will be

LA = 467.25 × 5

LA = $2336.25

Then the amount of winning will be

⇒ $ 6074.25 - $ 2336.25

⇒ $ 3738
