A salesperson's commission rate is 4%. What is the commission from the sale of $37,000 worth of furnaces? Use pencil and pape

MatroZZZ [7]

Answer:

<h2> The earnings will double</h2>

Step-by-step explanation:

Step one:

given data

we are told that the sales person's earnings is 4% of the sales made.

given that the sales made is $37,000 worth of furnaces.

Step two:

we want to find 4% of $37,000

=4/100*37000

=0.04*37000

=1480

hence for $37,000 the earning will be $1480.

Now suppose sales is doubled that is 37000*2= 74000

we want to find 4% of $74,000

=4/100*74000

=0.04*74000

=2960.

the earnings is $2960.

So if sales doubles the earnings will double

Find the output for the graph y = -6x + 25 when the input value is 3. = y = [?]

avanturin [10]

Answer

$x=\frac{11}{3}$

Explanation

Based on the given conditions, formulate:: $y=3$

Substitute $y=3$ into $y=-6x+25$ :: $3=-6x+25$

Rearrange variables to the left side of the equation: $6x=25-3$

Calculate the sum or difference: $6x=22$

Divide both sides of the equation by the coefficient of variable: $x=\frac{22}{6}$

Cross out the common factor: $x=\frac{11}{3}$

An analyst for a large credit card company is going to conduct a survey of customers to examine their household characteristics.

zheka24 [161]

Answer:

We can conclude that the value of 1732 is a statistic who represent the sample selected. And the value of 1622 represent the population mean from all the customers with the previous data.

Step-by-step explanation:

Previous concepts

A statistic or sample statistic "is any quantity computed from values in a sample", for example the sample mean, sample proportion and standard deviation

A parameter is "any numerical quantity that characterizes a given population or some aspect of it".

Solution to the problem

For this case the analyst knows that from previous records that the mean for all the customers (that represent the population of interest) is $\mu = 1622$

He have a random sample of n =500 customers from the previous month and he knows that 1732 represent the sample mean for the selected customers calculated from the following formula:

$\bar X = \frac{\sum_{i=1}^{500} X_i}{500}= 1732$

So on this case we can conclude that the value of 1732 is a statistic who represent the sample selected. And the value of 1622 represent the population mean from all the customers with the previous data.

Solve: 3 x ≤ 6 how do I do this plz help

timama [110]

Answer:

x ≤ 2

Step-by-step explanation:

Most of the properties of equality also apply to inequalities. The exception is multiplication (or division) by a negative number. An equation can be multiplied or divided by any number you like (except division by 0) and it will remain true. An inequality must have the relation symbol reversed when multiplying or dividing by a negative number.

Here, we don't run into that issue, because we can solve this by dividing both sides by the coefficient of x, which is +3.

(3x)/3 ≤ 6/3

x ≤ 2 . . . . . . . simplify
