Lina20 [59]

Answer: 97.72%

Step-by-step explanation:

Given : A shoe manufacturer collected data regarding men's shoe sizes and found that the distribution of sizes exactly fits the normal curve.

Let x be the random variable that represents the shoe sizees.

Also, The population mean = \mu=11 ; Standard deviation: \sigma=1.5

Formula for z:-

z=\dfrac{x-\mu}{\sigma}

Put x= 8, we get

z=\dfrac{8-11}{1.5}=-2

Now, the probability that the male shoe sizes are greater than 8 :-

P(x>8)=P(z>-2)=1-P(z\leq-2)\\\\=1-0.0227501=0.9772499\approx0.9772

Hence, the percent of male shoe sizes are greater than 8 is 97.72%.

Find the values of x and y.<br> y<br> 45
Mila [183]

Answer:

x = \sqrt{2}

y = 2

Step-by-step explanation:

By applying tangent rule in the given triangle,

tan(45°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

1 = \frac{\sqrt{2}}{x}

x = √2

By applying sine rule in the given triangle,

sin(45°) = \frac{\text{Opposite side}}{\text{Hyotenuse}}

\frac{1}{\sqrt{2}}=\frac{\sqrt{2}}{y}

y = (\sqrt{2})^2

y = 2
