A flower bed is in the shape of a triangle with one side twice the length of the shorter side and the third side is 26 feet more

horsena [70]

x - shortest side

2x - second side

x + 26 - third side

174 ft - perimeter

x + 2x + (x + 26) = 174

4x + 26 = 174 |-26

4x = 148 |:4

x = 37 ft

2x = 2(37) = 74 ft

x + 26 = 37 + 26 = 63 ft

Answer: 37 ft, 74 ft and 63 ft.

6. Suppose that a fair coin is tossed 2 times, and the result of each toss (H or T) is recorded.

nekit [7.7K]

Answer:

a) $S= {HH, HT, TH, TT}$

b) $P(X=0) = (2C0) (0.5)^0 (1-0.5)^{2-0}= 0.25$

$P(X=1) = (2C1) (0.5)^1 (1-0.5)^{2-1}= 0.5$

$P(X=2) = (2C2) (0.5)^2 (1-0.5)^{2-2}= 0.25$

And we have the following table:

X | 0 | 1 | 2

P(X) | 0.25 | 0.5 | 0.25

Step-by-step explanation:

Let's define first some notation

H= represent a head for the coin tossed

T= represent tails for the coin tossed

We are going to toss a coin 2 times so then the size of the sample size is $2^2 = 4$

a. What is the sample space for this chance experiment?

The sampling space on this case is given by:

$S= {HH, HT, TH, TT}$

b. For this chance experiment, give the probability distribution for the random variable of the total number of heads observed.

The possible values for the number of heads are X=0,1,2. If we assume a fair coin then the probability of obtain heads is the same probability of obtain tails and we can find the distribution like this:

$P(X=0) = (2C0) (0.5)^0 (1-0.5)^{2-0}= 0.25$

$P(X=1) = (2C1) (0.5)^1 (1-0.5)^{2-1}= 0.5$

$P(X=2) = (2C2) (0.5)^2 (1-0.5)^{2-2}= 0.25$

And we have the following table:

X | 0 | 1 | 2

P(X) | 0.25 | 0.5 | 0.25

(Y^2-3y^3-2+5y)-(7+8y^2-4y^2+6y^3

miv72 [106K]

Answer:

The answer to your question is: -9y³ - 3y² + 5y - 9

Step-by-step explanation:

( y² - 3y³ - 2 + 5y ) - (7 + 8y² - 4y² + 6y³)

y² - 3y³ - 2 + 5y - 7 - 8y² + 4y² - 6y³

Like terms -3y³ - 6y³ + y² - 8y² + 4y² + 5y - 2 - 7

-9y³ - 3y² + 5y - 9
