Answer:
The actual discount is a 68% discount.
Step-by-step explanation:
Remember that if something has a price P, and you have a discount of the X%, the new price will be:
P' = P - P*(X%/100%) = P*(1 - X%/100%)
Here we first have a 60% discount, then if the initial price is P, the new price is:
P' = P*(1 - 60%/100%) = P*(1 - 0.6)
Now we have an additional 20% discount (this applies to the new price)
then the final price is:
P'' = P'*(1 - 20%/100%) = P'*(1 - 0.2) = P*(1 - 0.6)*(1 - 0.2)
We want to rewrite this as something like:
P'' = P*(1 - k)
Let's do this:
P'' = P*(1 - 0.6)*(1 - 0.2) = P*(1 - 0.2 - 0.6 + 0.2*0.6)
= P*(1 - 0.8 + 0.12) = P*(1 - 0.68)
And this can be as:
P'' = P*(1 - 68%/100%)
Then the actual discount is a 68% discount.

Henri has $24,000 invested in stocks and bonds. The amount in stocks is $6,000 more than three times the amount in bonds
Answer:
s + b = $24,000
And,
s = 3b + $6,000
Step-by-step explanation:
Let us assume the stock be s
And, the bonds be b
So according to the question
It is given that
s + b = $24,000
And,
s = 3b + $6,000
The answers are
s + b = $24,000
And,
s = 3b + $6,000

If Johnny caught 2 out of 5 catfish on his first fishing trip how many catfish can he expect to catch if he caught a total of 60 fish?
60
24
600
6
Answer:
B, 24
Step-by-step explanation:
2 : 5 ratio of catching catfish
X : 60
2/5 = X/60
6 x (2/5) = (X/60) x 60
60 x (2/5) = X
X = 60 x (2/5)
X = 24
Therefore he can except to catch 24 catfish

The department of motor vehicles wants to check whether drivers have a slower reaction time after drinking two cans of beer. This was done by selecting a sample of 19 drivers and randomly assigning them to one of the two groups. The reaction times (measured in seconds) in an obstacle course are measured for a group of 10 drivers who had no beer. The other group of 9 drivers were given two cans of beer each and their reaction times on the same obstacle course are measured.
What is the parameter of interest?
a. The mean reaction times (measured in seconds)
b. The mean difference in reaction times between all those who drink no beers and all those who drink two cans of beer
c. The difference between the mean reaction time of the sample of those who drink no beers and the mean reaction time of the sample of those who drink two cans of beer
d. The difference between the mean reaction time of all those who drink no beers and the mean reaction time of all those who drink two cans of beer

If a kickball has the diameter of 12 inches , how much air could this call contain ?
Answer:
904.32. cu.in
Step-by-step explanation:
diameter= 12 inches
radius= 13/2=6 inches
volume of sphere= 4/3 πr³ = 4/3 ×π × 6³ = 904.32 cu.in
The amount of air contain in kickball is,
⇒ V = 904.32 in³
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A kickball has the diameter of 12 inches.
Hence, We get;
⇒ Radius = 12/2
⇒ Radius = 6 inches
Since, We know that;
⇒ volume of sphere= 4/3 πr³
Hence, We get;
⇒ V = 4/3 ×π × 6³
⇒ V = 904.32 in³
Thus, The amount of air contain in kickball is,
⇒ V = 904.32 in³

circle with solid boundary, center at (–6, –12), bounded solution set
circle with solid boundary, center at (6, 12), unbounded solution set
circle with solid boundary, center at (–6, –12), unbounded solution set
The characteristics describe in the graph of the circle inequality are a circle with a solid boundary, center at (6, 12), and bounded solution set option first is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have a circle equation in the inequality form:
(x – 6)² + (y – 12)² ≤ 196
The center of the circle is at (6, 12)
The radius of the circle is:
r² = 196
r = 14 units
After drawing a circle on the coordinate plane.
We will see, a circle with a solid boundary, center at (6, 12), and bounded solution set.
Thus, the characteristics describe in the graph of the circle inequality are a circle with a solid boundary, center at (6, 12), and bounded solution set option first is correct.
