Answer:

5.2 inches

Step-by-step explanation:

Let a be the side of the square poster.

The area of it is:

● A = a^2

● 27 = a^2

● a = √27

● a = √(9×3)

● a = 3√3

● a = 5.19

Round it to the nearest tenth

● a = 5.2 inches

A bag contains 6 red and 8 white balls. One ball is drawn at random. What is the probability that the drawn is white?
wel

If it's three or more, the probability is 100%.

However, I will assume that you intend to draw only two balls and that you don't replace the first ball in the bag for the second draw.

So you draw one ball. The probability that it's red is 8/14 = 4/7.

You draw again. The probability of getting a second red is 7 (red balls remains) / 13 (balls remaining).

Assuming that the results of the first and second draws are independent,the probability of drawing two red balls is therefore (4/7)*(7/13) = 4/13.

Now, suppose instead of a red on the first draw you got white. The probability of this is 6/14 = 3/7.

Given the first ball is white, the probability of drawing a second white is 5/13.

So the probability of drawing two whites is (3/7)*(5/13) = 15/91.

The outcomes of drawing two reds or two whites are independent of each other, so you can add the probabilities to get the probability of drawing two balls of the same colour, i.e.

4/13 + 15/91 = 43/91

If you prefer to express it as a percentage, it's approximately 47.25%.

the problitiy is that a sweet stawberry flavor is 0.8 what is the problity is that a sweet is orang flavor what is anwer
dsp73

Answer:

\huge\boxed{Answer\hookleftarrow}

Assuming that there are only 2 flavors of the sweet ⇻ strawberry & orange.

____________________

P (strawberry flavored sweet) = 0.8

P (orange flavored sweet) = ?

____________________

Now, we know that ➳ the value of probability ≤ 1. So, the probability of orange flavored sweets is less than 1.

____________________

So,

P (orange flavored sweet) = 1 - P (strawberry flavored sweet)

P (orange flavored sweet) = \large\bold{1.0 - 0.8}

P (orange flavored sweet) = \large\bold{0.2}

____________________

✐ The probability that the sweet is orange flavored is <u>0</u><u>.</u><u>2</u>

Don’t understand this question pllsss helppp
Elza [17]

Answer:

A. -50

Step-by-step explanation:

The question is asking you to find the Y point as they gave you the X.

(0,-50). -50 on the y-axis explains the x of 0. If you though it was 14 or -6, it is not because they have the x of -6 and the y of 0.
