<u>Given</u>:

Let the random variable x is normally distributed with mean \mu=90 and \sigma=5

We need to determine the probability of P(X

<u>Probability of </u>P(X<u>:</u>

The formula to determine the value of P(X is given by

Z=\frac{X-\mu}{\sigma}

Thus, we have;

P(X

Simplifying, we get;

P(X

P(X

Using the normal distribution table, the value of -2 is given by 0.0228

P(X

Thus, the value of P(X is 0.0228

3. The annual per capita consumption of fresh bananas in the United States can be approximated by a normal distribution, with a
svlad2 [7]

Answer:

The largest annual per capita consumption of bananas in the bottom 5% of consumption is 5.465 lb

Step-by-step explanation:

Given

μ = Mean = 10.4 lb

σ = Standard deviation = 3 lb

Using a confidence level of 90%,

We'll need to first determine the z value that correspond with bottom 5% of consumption of banana

α = 5%

α = 0.05

So,

zα = z(0.05)

z(0.05) = -1.645 ----- From z table

Let x represent the largest annual per capita consumption of bananas

The relationship between x and z is

x = μ + zσ

By substitution;

x = 10.4 + (-1.645) * 3

x = 10.4 - 4.935

x = 5.465

Hence, the largest annual per capita consumption of bananas in the bottom 5% of consumption is 5.465 lb

Two sides are congruent to each other.

The third side of an isosceles triangle which is unequal to the other two sides is called the base of the isosceles triangle.

A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.

A triangle with all sides of different lengths. All angles are different, too. So no sides are equal and no angles are equal.
