The ratio of the measures of the sides of a triangle is 3:4:5. Its perimeter is 48 inches. Find the scale factor as a decimal, a

Trava [24]

Given:

The ratio of the measures of the sides of a triangle is 3:4:5.

Its perimeter is 48 inches.

To find:

The scale factor as a decimal, and the measure of each side of the triangle.

Solution:

Let x be the scale factor. Then the measures of sides of the triangle are 3x, 4x and 5x.

The perimeter of the triangle is 48 inches. It means the sum of all sides of the triangle is 48 inches.

$3x+4x+5x=48$

$12x=48$

Divide both sides by 12.

$x=\dfrac{48}{12}$

$x=4$

Now, the measures of sides are:

$3x=3(4)$

$3x=12$

Similarly,

$4x=4(4)$

$4x=16$

And,

$5x=5(4)$

$5x=20$

Therefore, the scale factor is 4 and the measures of sides are 12, 16 and 20.

According to a National Health Survey, American men’s heights are normally distributed with a mean given by μ=69.7 inches and a

Novay_Z [31]

Answer: 0.206

Step-by-step explanation:

Given that :

Height of American men is normally distributed :

Mean height (μ) = 69.7 inch

Standard deviation (σ) = 2.8 inch

Probability that height of a randomly selected man is more than 72 inches

P(X > 72)

Obtain the standardized score (Zscore):

Zscore = (x - μ) / σ

Zscore = (72 - 69.7) / 2.8

Zscore = 2.3 / 2.8

Zscore = 0.8214285

Zscore = 0.8214

Using the Z probability calculator ;

P(Z > 0.8214) = 0.20571

Probability of selecting a man whose height is more Than 72 is 0.206

If someone offers you a lottery ticket that has a 25 percent chance of winning $100, a 50 percent chance of winning $200, and a

g100num [7]

Answer: $375

Step-by-step explanation:

Given : The probability of winning $100 : P(100)= 0.25

The probability of winning $200 : P(200)= 0.50

The probability of winning $1000 : P(1000)= 0.25

Now, the the expected value of that lottery ticket is given by :-

$P(100)\times 100+P(200)\times200+P(1000)\times1000\\\\=0.25\times100+0.50\times200+0.25\times1000\\\\=375$

Hence, the the expected value of that lottery ticket =$375
