Answer:
Salesperson would earn $13.6 in commission for selling a microwave oven for $340.
Step-by-step explanation:
We are given that an appliance salesperson earned $32.80 in commission for selling a refrigerator for $820.
We have to find how much would the salesperson earn in commission for selling a microwave oven for $340.
Firstly, we will the find the rate at which the salesperson gets a commission in % terms.
So, Percentage rate of commission is given by;
Rate of commission=(Commission earned ÷ Selling Price of refrigerator) 100
= = = 4%
Now, this rate will be used to find the commission earned on selling a microwave oven for $340, i.e;
Commission earned for selling a microwave oven = 4% of Selling price of microwave oven
= = $13.6
Therefore, salesperson would earn $13.6 in commission for selling a microwave oven for $340.

Select all expressions that are equivalent to 6(7a + 9b).
(1 Point)
3(14a + 18b)
2(11a + 13b)
42a + 9b
42a + 546
Answer:
6(7a + 9b) = 3(14a + 18b)
Step-by-step explanation:
We need to find the equivalent expression for the given expression i.e. 6(7a + 9b).
We can use the distributive property here such that,
a(b+c) = ab + ac
We have, a = 6, b = 7 and c = 9
6(7a + 9b) = 6(7a) + 6(9b)
= 42a + 54b
or taking 3 common from the above expression.
= 3(14a+18b)
Hence, the correct option is (a).
The width of the rectangle
is one-fourth of its length.
If the perimeter is 40 cm,
find the dimensions of the
rectangle.
4w = L
2L + 2w = 40
Answer:
84cm^2
Step-by-step explanation:
P=2l+2w
We are given,
P=40cm
l=2w+2
Plug these into the first formula and solve for the dimensions,
length and width, of the rectangle:
40=2(2w+2)+2w Simplify
40=4w+4+2w
40=6w+4
36=6w
6=w OR the width is 6cm, therefore,
the length is
l=2(6)+2
l=14cm
To calculate the area of a rectangle, A=lw,
plug the length,14cm, and the width, 6cm, into this formula
A=(14)(6)
A=84cm2 OR the area of the rectangle is 84cm^2

Find the perimeter of a rectangle if
the area is 45 cm2 and the base is 7.5 cm
Answer:
27 cm.
Step-by-step explanation:
Area = base * height
45 = 7.5 * h
h = 45/7.5
= 6 cm.
So the perimeter
= 2(base + h)
= 2(7.5 + 6)
= 27 cm.

3. Ashley must choose between two job offers.
• Job A pays a flat rate of $21.50 plus an additional $9.75 per hour.
Job B pays a flat rate of $10.95 plus an additional $11.40 per hour.
Which inequality can be used to find x, the number of hours when Job A will earn more than Job B.
9.75 + 21.50x > 11.40 + 10.95%
9.75 + 21.50x < 11.40 + 10.95x

Cystic fibrosis (CF) is a hereditary lung disorder that often results in death. It can be inherited only if both parents are carriers of an abnormal gene. In 1989, the CF gene that is abnormal in carriers of cystic fibrosis was identified. The probability that a randomly chosen person of European ancestry carries an abnormal CF gene is 1/25. (The probability is less in other ethnic groups.) The CF20m test detects most, but not all, harmful mutations of the CF gene. The test is positive for 90% of people who are carriers. It is never positive for people who are not carriers.
Required:
Compute the probability that a randomly chosen person of European ancestry does not carry an abnormal CF gene given that he /she tested negative.
Answer:
0.9959 = 99.59% probability that a randomly chosen person of European ancestry does not carry an abnormal CF gene given that he /she tested negative.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Tested negative
Event B: Does not carry an abdornal CF gene.
Probability of a negative test:
10% of 1/25 = 0.04 = 4%
100% of 100 - 4 = 96%. So
[tex]P(A) = 0.1*0.04 + 1*0.96 = 0.964[/tex]
Negative test and not carrying an abdornal gene:
100% of 96%. So
[tex]P(A \cap B) = 1*0.96 = 0.96[/tex]
Compute the probability that a randomly chosen person of European ancestry does not carry an abnormal CF gene given that he /she tested negative.
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.96}{0.964} = 0.9959[/tex]
0.9959 = 99.59% probability that a randomly chosen person of European ancestry does not carry an abnormal CF gene given that he /she tested negative.

Step-by-step explanation:
For each problem, we just "plug in" the x value into the equation. For example, in the first box the x value is 2 and the equation is y = x + 9. Since we know that x is equal to -2, then the equation becomes y = -2 + 9, and y becomes 7.

find the slope and y-intercept
Answer:
Slope: -2
y-intercept: -3 or (0, -3)
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
6x+3y= -9
3y = -6x - 9
y = -2x - 3
A commercial jet flies 1,500 miles with the wind. In
the same amount of time it can fly 1,000 miles against the
wind. The speed of the jet in still air is 550 mph. Find the
speed of the wind.
Answer:
As below
Step-by-step explanation:
we want to know how long it took to fly so make two equations and set them equal to each other using the variable t
so, use d = r*t where d= distance , r= rate ( speed) and t = time
w= wind velocity (speed with direction)
1500=(w+550)*t
1000=(-w+550)*t
now make both equations with respect to t
1500/(w+550) = t
1000/(-w+550) = t
since they are both equal to t, where t is the same amount of flying time, set the two equations equal to each other
1500/(w+550) = 1000/(-w+550)
now solve for w
1500w + 825,000 = -1000w+550,000
2500w= -275,000
w = - 110
the wind speed is 110 opposite of the planes direction but also, if the plane flies in the other direction with it.
wind velocity (velocity is speed with a direction ) is 110 MPH
they are asking for speed, b/c we don't know anything about direction... that is which direction is the plane headed during it's flight therefore we also can't say anything about the wind direction either. :|

A bakery works out a demand function for its chocolate chip cookies and finds it to be q = D(x) = 760 - 13x, where is the quantity of cookies sold when the price per cookie, in cents, is x.
A) Find the elasticity.
B) At what price is the elasticity of demand equal to 1?
C) At what prices is the elasticity of demand elastic?
A. Prices are elastic at all values.
B. Prices cannot be elastic in this case.
C. Greater than.
D. Less than .
D) At what prices is the elasticity of demand inelastic?
A. Greater than.
B. Less than.
C. Prices are inelastic at all values.
D. Prices cannot be inelastic in this case.
E) At what price is the revenue a maximum?
F) At a price of ¢ per cookie, will a small increase in price cause the total revenue to increase or decrease?
A. Increase.
B. Decrease.
Answer:
1. 13x/760-13x
2. X = 29.23
3. X> 29.23
4. X<29.23
5. Max price = 29.23c
Step-by-step explanation:
1. D(x) = 760-13x
To get Elasticity, we differentiate the equation
D'x = -13
Elasticity is expressed as:
E(x) = -x*D'(x)/760-13x
= X(-13)/760-13x
[tex]\frac{-13x}{760-13x}[/tex]
B. Price elasticity with demand = 1
13x/760-13x = 1
We cross multiply
13x = 1(760-13x)
13x = 760-13x
Collect like terms
26x = 760
X = 29.23
C. When elasticity of demand is elastic
13x/760-13x > 1
We cross multiply
13x > 1(760-13x)
13x > 760-13x
Collect like terms
26x > 760
X > 29.23
C. Greater than 29.23
D. When inelastic
This follows same solution as 2 and 3 but the sign is different.
E(x) <1
13x/760-13x < 1
We cross multiply
13x < 1(760-13x)
13x < 760-13x
Collect like terms
26x < 760
X < 29.23
B. less than 29.23
E. We get total revenue
X(760-13X)
= 760x - 13x²
We differentiate this
760-26x = 0
760 = 26x
X = 29.23
revenue is a maximum at price is 29.23c
f. The last question is incomplete
