Consider functions f and g.



Which expression is equal to f(x) ⋅ g(x) ?

Answer:

[tex]\boxed {\boxed {\sf z=2.8}}[/tex]

Step-by-step explanation:

The z-score helps describe a value's relationship to the mean. It tells us how many standard deviations a value is from the mean. The formula is:

[tex]z= \frac{x- \bar x}{s}[/tex]

where x is the value, x-bar is the mean, and s is the standard deviation.

We know the data set has a mean of 25 and a standard deviation of 5. The value we are finding the z score for is 39.

Substitute the values into the formula.

[tex]z= \frac{ 39-25}{5}[/tex]

Solve the numerator.

[tex]z= \frac{ 14}{5}[/tex]

[tex]z=2.8[/tex]

The z-score for 39 is 2.8. This means a value of 39 is 2.8 standard deviations greater than the mean.

Answer:

Step-by-step explanation:

the donkey eats 3/5 of hay bale a week

3/5 x 2 = 6

the donkey eats 6 hay bales in 10 weeks

The amount of bales the donkey eats in 10 weeks is 6 bales.

Given,

A donkey eats three-fifths of a hay bale a week.

We need to find out how many bales he eats in 10 weeks.

Example:

2 miles in 1 hour

2 miles = 1 hour

To find miles in 4 hours we multiply both sides by 4.

4 x 2 miles = 4 x 1 hour

8 miles = 4 hours

We have,

Donkey eats:

3/5 bales = 1 week ____(1)

In 10 weeks:

Multiply 10 on both sides of (1)

10 x 3/5 bales = 10 x 1 week

6 bales = 10 weeks

Thus the amount of bales the donkey eats in 10 weeks is 6 bales.

The probability is P = 0.894

a) Determine the probability that a student will begin college during the summer semester and attend an in-state college.

The probability is given by the quotient between the number of students that start on summer semester and attend to an in-State college, and the total number of students that start on the summer semester.

The number of students starting on the summer semester is:

178 + 21 = 199

Of these 199 students, 178 will attend to an in-state college, so our probability is:

P = 178/199  = 0.894

Step-by-step explanation:

We are given a 45°-45°-90° triangle with hypotenuse measuring 18 cm.

Let us assume the following labeling of the diagram, as attached in the answer area.

The two angles here are equal to 45° so two sides of the triangle opposite to the equal angles will also be equal to each other i.e. it is an isosceles triangle.

i.e. The sides XY and YZ will be equal.

Let XY = YZ = x cm

It is known that in a right angled triangle, pythagorean theorem holds well.

As per pythagoream theorem:

Putting the values:

So, the length of leg of triangle =

Answer:  standard deviation = 8

This is because mu = 75 is the mean, which is at the very exact center of this distribution. One space to the right is 83, which is 83-75 = 8 units away from the center. This distance is exactly one standard deviation. We can say "83 is one standard deviation larger than 75".

Or you could note the distance from 67 to 75 is also 8, because 75-67 = 8. Each tickmark represents stepping one standard deviation in distance.

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

An inequality is a mathematical statement which compares two values or expressions using a relational operator, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), or not equal to (≠). Inequalities are used to show relationships between quantities or to express constraints or conditions.
