Answer:

x = -1.75 , +/- 1.1892i.

Step-by-step explanation:

4x5 + 7x4 + 36x + 63) = (4x + 7)

4x^5 + 7x^4 + 32x + 56 = 0

x^4(4x + 7) + 8(4x + 7) = 0

(x^4 + 8) = 0 or 4x + 7 = 0

4x + 7 = 0

x = -1.75.

4x^4 = -8

x^4 = -2

x = +/- ⁴√-2

x = +/- 1.1892 i.

A store charges $2.10 for a medium bag of fruit slices. Assuming that the rate stays the same, how much should the store charge

melomori [17]

Hey there,

Your question states: <span>A store charges $2.10 for a medium bag of fruit slices. Assuming that the rate stays the same, how much should the store charge for a large bag of the slices?

So sense this is a medium bad of fruit slices, we would divide 2.10 by 2.

Your answer would be 1.5 Now, all we do is we add 2.10+1.5 and we get 3.15. The reason would be because sense we now know the price of the size of it being small, we just add that size on top of the medium size to get 3.15.

Hope this helps.

Rosa is attending an event where prizes are being given away. The probability of winning a T‐shirt is 0.89 and the probability o

vagabundo [1.1K]

Answer:

It is very likely that Rosa wins both prizes.

Step-by-step explanation:

The probability of winning a T‐shirt is 0.89 and the probability of winning a $20 gift certificate is 0.05. Which statement correctly describes the chances of Rosa winning a T‐shirt or a $20 gift certificate?

We have these three possibe outcomes.

Win t-shirt(0.89 probability) and lose the gift certiciate(1 - 0.05 = 0.95 probability)

Lose t-shirt(0.11 probability) and win the gift certiciate(0.05 probability).

Win both.

$p = 0.89*0.95 + 0.11*0.05 + 0.89*0.05 = 0.8955$

0.8955 = 89.55% probability of Rosa winning a T‐shirt or a $20 gift certificate, which is considered a very likely probability. So the answer is:

It is very likely that Rosa wins both prizes.
