Answer:

R(x) = (460 * 7x)*(20+ x)

Step-by-step explanation:

If exactly 20 people sign up :

Charge per person = $460

For passengers after 20:

At number of passengers = 20 ;

Cost = (fee * discount * number of additional passesengers) * (20 + Number of additional passengers

Let number of additional passengers after 20 = x

R(x) = ($460 * $7x) * (20 + x)

Hence,

R(x) = (460 * 7x)*(20+ x)

Answer:

Step-by-step explanation:

Where a transversal (t or u) crosses parallel lines (m and n), there are four angles formed at each intersection. Corresponding and vertical angles are congruent.

Angles in a linear pair are always supplementary. Of course, the angles interior to a triangle always total 180°. These facts let you find the relationships of all the angles in the figure.

Angle 13 corresponds to the given angle 52°, so has the same measure. Angles 4 and 18 are vertical angles with respect to those, so also have the same measure. Angles 1 and 3, 14 and 17 are supplementary to the ones just named, so all have measure 128°.

In the same way, angles on the other side of the figure can be found from the one marked 44°. Angles 5, 12, and 15 also have that measure; and angles 2, 6, 11, and 16 are supplementary, 136°. Angles 7 and 10 finish the triangle interior so that its sum is 180°. That means they are 180° -52° -44° = 84°. Of course, angles 8 and 9 are the supplement of that value, 96°.

In summary:

The expression that is equal to 3B - C in standard form is 2.0 × 10¹

From the question, we are to determine the value of the expression

The given expression is

3B - C

From the given information,

B = p + 6

and

C = 3p - 2

Putting the the values of  B and C into the expression, we get

3B - C = 3(p + 6) - (3p -2)

= 3p + 18 -3p + 2

= 3p - 3p + 18 + 2

= 20

= 2.0 × 10¹

Hence, the expression that is equal to 3B - C in standard form is 2.0 × 10¹

Answer:B major arc

Step-by-step explanation:

edg

The arc CDE shown in the figure attached in the question describes a major arc. The correct option is B.

A major arc in a circle is an arc that shows that its measurement is greater than that of 180°. A major arc is one with a measure greater than 180 degrees.

A semicircle is an arc that divides a circle in half and has a measure of 180 degrees. A circle's endpoints can be used to define two semicircles or one minor arc and one major arc.

From the given figure, the arc CDE shows that the arc is greater than 180°, so it can be referred to as the major arc.

A minor arc is an arc that is less than 180°

A semicircle is an arc that is equal to 180°

Therefore, the correct option is B.

Answer:

We fail to reject the null

Step-by-step explanation:

Given the data: 1298; 1229.96; 1193.07; 1279; 1224.98; 1229.97; 1269.98; 1248

Mean price, μ = 1249

Standard deviation, σ = 25

Variance, σ² =

Null hypothesis, H0 : σ² = 25²

Alternative hypothesis, H1 : σ² > 25

Using calculator, the sample standard deviation :

Sample standard deviation = s = 34.072

Sample size, n = 8

For chi² distribution :

X² = [(n - 1)s²] ÷ σ²

X² = [(8 - 1)*34.072^2] ÷ 25^2

X² = (7 * 1160.901184) / 625

X² = 13.002093

Using the Pvalue from Chisquare calculator, df = 8 - 1 = 7; α = 0.05

Pvalue =0.07206

0.07206 > 0.05

Since , Pvalue > α

We fail to reject the null; there is insufficient evidence to conclude that standard devuatue do selling a computer is greater than 25

Answer:

(f о g)(0) = 24

Step-by-step explanation:

f(x) = -5x - 1

g(x) = x² - 5

When you see (f о g)(#), they want you to plug the function g(x) into the function f(x).

First find g(0).

g(0) = (0)² - 5

g(0) = 0 - 5

g(0) = -5

Now plug g(0) = -5 into f(x) by replacing all x's with -5.

(f о g)(0) = -5(-5) - 1

Multiply.

(f о g)(0) = 25 - 1

Subtract.

(f о g)(0) = 24

Answer: a. It is commonly referred to as the arithmetic average.

b. It is algebraically defined (that is, there is an equation you can use to calculate its value).

c. It is easily influenced by extreme scores.

Step-by-step explanation:

The mean is also referred to as the "average" and it is gotten by adding every number and the dividing the value gotten by the number of the numbers used for the calculation.

It should be noted that the mean is algebraically defined and can be easily influenced by extreme scores.
