Ayden is a salesperson who sells computers at an electronics store. He makes a base pay amount of $90 per day regardless of sales and he earns a commission of 1% of the dollar amount of all sales that he makes. Write an equation for the function P(x),P(x), representing Ayden's total pay on a day on which he sells xx dollars worth of computers

Hi there, here's your answer:

Given 2 angles:

(6d + 8)° and (8d + 4)°

Observe the figure carefully. You will notice that the two angles form a linear pair.

We know that in a linear pair, sum of the two angles = 180°.

Hence,

(8d + 4 + 6d + 8)° = 180°

(14d + 12)° = 180°

(14d)° = (180 - 12)°

= 14d = 168°

Or

d = 12

Thus, we find the value of d to be d = 12.

The function in Excel that we should use to find a measurement M given a right-tail probability (or area) A is = NORM.INV(1-A, mu, sigma)

In order to find a measurement M given a right-tail probability A in Excel, we can use the NORM.INV function. The NORM.INV function in Excel returns the inverse of the normal cumulative distribution for a given probability.

The formula for NORM.INV function is:

= NORM.INV(1-A, mu, sigma)

where:

A is the right-tail probability (or area)

mu is the mean of the distribution

sigma is the standard deviation

The function returns the measurement M such that the right-tail area from M to infinity under the normal curve is equal to A.

Note - In some versions of Excel, the function may be called NORM.INV.RT instead of NORM.INV.

Answer:

Solution to system of inequalities is y≥ 3x-2

Graph attached

Step-by-step explanation:

We have the following two inequalities:
y>-3x-5

y≥ 3x-2

To get the solution and graph

1. Graph each inequality separately

2. Choose a test point to determine which side of the line needs to be shaded

3. The solution will be the area where the shadings from each inequality overlap one another

The graph is attached. The heavily shaded region is the set of all points which satisfy all inequalities

We see that any point that satisfies y≥ 3x-2  also satisfies y>-3x-5

In other words, the solution set for y≥ 3x-2 is a subset of the solution set for   y>-3x-5

There are 10/4 ways ( [tex]\frac{10}{4}[/tex] ) to accomplish the given task by wearing the ties for a week according to the permutations and combinations.

Given if you wear tie for a week, where one need t wear 4 of his ties from the 10 of total. The number of ways to wear the ties will be equal to the value. So there are many ways to wear a tie of different types and also to remove the tie there are different ways. Now we will see the ways to wear a tie accordingly.

According to the permutations and combination rules the formula will be:

Number of ways: (Number of ties want to wear) / (Number of Total ties)

Therefore total number of ways to wear ties = 10/4

Number of ways this can be accomplished is 10/4

Step-by-step explanation:

One chocolate chip cookie costs $0.50. This is found by setting up two equations using the given information and solving for the cost of one cookie.

To solve this problem, we can assume that the cost of one jumbo popcorn is P and the cost of one chocolate chip cookie is C. We can then set up two equations based on the given information.

The first equation comes from Julia's purchase, which includes one jumbo popcorn and two chocolate chip cookies. We know the total cost is $5.0, so we can write:

1P + 2C = 5.0

The second equation comes from Marvin's purchase, which includes one jumbo popcorn and four chocolate chip cookies. We know the total cost is $6.0, so we can write:

1P + 4C = 6.0

To solve for the cost of one chocolate chip cookie, we can eliminate P by adding the two equations. This gives us:

2P + 6C = 11.0

Dividing both sides by 2, we get:

P + 3C = 5.5

We can then substitute the value of P in terms of C from either of the two original equations into this equation, and solve for C. In this case, it's easier to use the first equation:

1P + 2C = 5.0

P = 5.0 - 2C

Substituting into the equation we just obtained:

(5.0 - 2C) + 3C

= 5.5

Simplifying and solving for C, we get:

C = 0.5

Therefore, one chocolate chip cookie costs $0.50.

Sidney will use 54 cups of soda for 17 cups of ice cream, So the answer is 54 cups.

What is the ratio?

A ratio is a relationship between two things when it is expressed in numbers or amounts. For example, if there are ten boys and thirty girls in a room, the ratio of boys to girls is 1:3, or one to three.

We can start by noticing that the ratio of cups of ice cream to cups of soda used to make the floats is always 1:3.

To find out how much soda Sidney will use for 17 cups of ice cream, we can set up a proportion:

3.5/10.5 = 8/24 = 12.5/37.5 = 17/x

Solving for x, we can cross-multiply:

3.5x = 10.5 * 17

x = 54

Therefore, Sidney will use 54 cups of soda for 17 cups of ice cream, So the answer is 54 cups.

The value of correlation cofficient between the number of people who complete successfully complete each jump, y and height of jump, x is equals to the - 0.091.

We have a table which consists height ( in feet ), x and completions, y present above figure. We have to calculate the correlation coefficient for variables x and y. Correlation coefficients are used to measure how strong the relationship is between two variables. The commonly used cofficient in linear regression is Pearson's correlation (also called Pearson's R) coefficient . Formulas return a value between -1 and 1, where,

Formula used to determine the cofficient is r = (n∑ xy - (∑x)(∑y))/√[ n∑x² - (∑x)²][n∑y² - (∑y)²]

Here, n = 6, ∑xy = 375.8 , ∑ x =22.4, ∑y

= 102, ∑ x² = 96.5, ∑y² = 1978

so, r = 6×(375.8) - 102(22.4))/√[(6×96 - (22.4)²)(6×1978 - 102²)]

= -30/329.68

= - 0.091

Hence, required value of r is - 0.091.

3. The amount that should be returned to Meenaski for buying 12 books worth R250.75 each and giving the shopkeeper R4,000, using mathematical operations, is R991.

4. The number of crayon sets that can be bought for R2,750 if one set costs R25, using division operation, is 110.

5. Manu will pay R1,700, exchanging his old bike for a new bike.

The four basic mathematical operations include addition, subtraction, division, and multiplication.

These mathematical operations are performed to solve algebraic problems using the relevant mathematical operands and rules.

The number of books bought = 12

The unit cost of each book = R250.75

The total cost of the 12 books = R3,009 (R250.75 x 12)

The amount advanced to the cashier = R4,000

The balance to be returned = R991 (R4,000 - R3,009)

The cost of a set of crayon = R25

The amount of money for the purchase = R2,750

The number of crayon sets that can be bought with R2,750 = 110 (R2,750/R25).

The price of the new bicycle = R2,500

The value of the old bike for exchange = R800

Speed of Ana =  7.5miles/hour

Step-by-step explanation:

Given,

Ana runs 3/4 mile in 6 minutes.

To find,

The speed of Ana in miles per hour

Recall the formula,

Speed = distance travelled/time taken

60 minutes = 1 hour

Solution:

Distance traveled = 3/4 mile

Time taken = 6 minutes

Since 60 minutes = 1 hour, we have

1 minute =1/60 hour

6 minutes = 6/60 hour

=1/10  hour

Hence speed  = distance travelled/time taken

=  3/4 / 1/10 miles/hour

= 15/2 miles/hour

= 7.5miles/hour

∴ Speed of Ana =  7.5miles/hour

The surface area of the sphere is 113.2 ft².

The area that a sphere's outer surface covers in three dimensions is known as the surface area of the Sphere. A sphere is a three-dimensional solid that resembles a circle in shape and is round.

The formula for a sphere's total surface area is given by

Here we have

The formula for the radius of a sphere r = 1/2 [√S/π]    

Diameter of the Moeraki boulder radius = 3 feet

=> 3 feet =  1/2 [√S/π]    

=> 6 = [√S/π]

Squaring on both sides

=> 36 = [√S/π]²

The given function is an exponential function.

The parent function is the basic equation before the function has undergone any transformation(s).  Therefore, the parent function of the given function is:

The range of the parent function is restricted to positive real numbers as it never takes a negative value.  Furthermore, it never reaches zero (although it approaches y = 0 as x → -∞).  Therefore, the range of the parent function is {y | y > 0}.

As the given function has been translated up 9 units (by the addition of "+ 9"), the range of the given function is translated 9 units up.  So as x approaches negative infinity, y approaches (but never reaches) 9. Therefore, the range of the given function is:
