Step-by-step explanation:
Price of mixer = 45.00$
Price of mixer with tax = 47.70
Tax added to the price of mixer = 45 - 47.70
= 2.70$
Percentage of Tax added to the price of mixer
= 2.70 = P multiplied by 45
(divide 2.70 by 45 and 45 by 45 as well)
= 0.06 = P
(we have to now convert the decimal to a percentage)
= 0.06 multiplied by 100 = P
6% = P

uhm, im not very good at explaining, but everytime the year increases, the population will exponentially increase, that's why 't' is an exponent
Answer:
[tex]y=320000(1.021)^t[/tex]
Step-by-step explanation:
To increase something by x% mulitply it by (1+x)
in other words, to increase sometihng by 2.1% mulitply it by
(1+.021) or 1.021
because we are mulitplying 320000 by 1.021 each year we can write the equation as
y=320000(1.021)^t

What is equation of line?The slopes of the line as well as a point just on line can be used to create the line equation. To better comprehend how the equation for a line is formed, let's learn more about the line's slope and the necessary point on the line.
The slope of the line, which can be stated as a quantitative integer, fraction, or perhaps the tangential of the angle it forms with the positive x-axis, is the line's inclination with respect to the positive x-axis. x – y = 0 is the equation of the graphed line written in standard form.

The government claims that the average age of Texans is 38 years. Blake hypothesizes that the average age of the population of Texas is not equal to 38 years. Blake records a sample mean equal to 41 and states the hypothesis as u = 38 vs u 38.

c.) Left-tailed test
d.) Upper-tailed test
Answers
Answer:
b.) Two-tailed test
Step-by-step explanation:
Blake hypothesizes that the average age of the population of Texas is not equal to 38 years.
This means that at the alternative hypothesis, we test if the average is different of 38, that is:
[tex]H_1: \mu \neq 38[/tex]
When the test at the alternative hypothesis is of difference, we have a two-tailed test, and thus the answer is given by option b.

Answers
Answer:
When using this technique, the AOQ:
improves (AOQ becomes a smaller fraction).
Step-by-step explanation:
AOQ simply means Average Outgoing Quality, which improves with inspection. It is a part of an organization's Acceptance Sampling Plan, usually designed to meet product quality and risk level targets. The plan draws samples from a population of items. Then it tests the samples. It only accepts the entire population if the sample is considered good enough. It also rejects the population when the sample is poor enough. In the plan, information about sample size and critical acceptance or rejection numbers are clearly indicated. Acceptance sampling is common in most business environments because it has been found to be more economical than doing 100% inspection of incoming production input and output.

Answers
By the chain rule, you have
dy/dx = dy/du * du/dx
For the function y = f(x) = (1 + 8x)^(1/2), you're taking
y = u ^(1/2)
u = 1 + 8x
These have derivatives
dy/du = 1/2 u ^(-1/2)
du/dx = 8
which means
dy/dx = 4u ^(-1/2) = 4 (1 + 8x)^(-1/2)

The profits in hundreds of dollars, P(c), that a company can make from a product is modeled by a function of the price, c, they charge for the product: P(c) = –20c2 + 320c + 5,120. What is the maximum profit the company can make from the product?
Answers
Answer:
6400
Step-by-step explanation:
Given the profit function ;
P(c) = –20c2 + 320c + 5,120
The maximum value is given by :
f(h) ; where, h = - b /2a
From P(C) ; a = - 20 ; b = 320
h = - b / 2a = - 320 / 2(-20) = - 320 / 40 = 8
c = h
P(8) = –20(8)² + 320(8) + 5,120
P(8) = - 1280 + 2560 + 5120
= 6400

Answers
Answer: 23.07$ (Option B)
Step-by-step explanation:
Lula's Budget per day = 45%
Cost spent on two meals = breakfast + lunch

How much does Lula has for dinner = 45$ - 21.93$
= 23.07$
Determine the equation of the circle shown in the graph.
Answers
Answer:
B.
Step-by-step explanation:
The equation of a circle with center at (h, k) and radius r is
[tex] (x - h)^2 + (y - k)^2 = r^2 [/tex]
We have center at (-5, 0). That makes h = -5, and k = 0.
The radius is 3, so r = 3.
[tex] (x - (-5))^2 + (y - 0)^2 = 3^2 [/tex]
[tex] (x + 5)^2 + y^2 = 9 [/tex]
Answer: B.
Answer:
B
Step-by-step explanation:
The equation of a circle has the form:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center of the circle and r is the radius.
From the graph, we can see that the center of the circle is at (-5, 0). So, (h, k) is (-5, 0), where h = -5 and k = 0.
And by counting, we can determine that the radius of the circle is three units. Hence, r = 3.
Substitute the information into the equation:
[tex](x-(-5))^2+(y-(0))^2=(3)^2[/tex]
Simplify. Therefore, our equation is:
[tex](x+5)^2+y^2=9[/tex]
Our answer is B.

Set up an equation and find the missing value of x.
Answers
Answer:
x = 35
Step-by-step explanation:
The angles shown are vertical angles
Vertical angles are congruent
Hence, 80 = 2x + 10
( Note that we just created an equation that we can use to solve for x )
We now solve for x using the equation we created
80 = 2x + 10
Step 1 subtract 10 from each side
80 - 10 = 70
10 - 10 cancels out
We now have 70 = 2x
Step 2 divide each side by 2
70/2 = 35
2x / 2 = x
We're left with x = 35

If you are selling your house with a local realtor who requires a 5 % commission fee, what can you expect to pay the realtor if your house sells for $182,000?
Answers
Answer: $9100
Step-by-step explanation:
Since the local realtor will get a commission of 5% whenever the house is sold, then the amount they the realtor will be paid when the house is old for $182000 will be calculated thus:
= 5% × $182000
= 5/100 × $182000
= 0.05 × $182000
= $9100
The realtor will be paid $9100.
