Answer:
B. (-infinity, 1)
Step-by-step explanation:
Remember that domain is left to right, and range is down to up.
Question asks to find where the domain is increasing
Increasing means when the line increases
look left, the line extends infinitely in the negative direction: -infinity
There is a discontinuity at 1, and then the line decreases. So that would be the second point
The interval at which the domain is increasing is

The length of a rectangle is four more than three times it’s width. The perimeter is 64 inches
Answers
Answer:
Length: 25, Width: 7
Step-by-step explanation:
Let the width be represented by w. We can then assume that the length is equivalent to 3w+4
So, we can set the equation 2(3w+4)+2(w). Simplify to 8w+8=64
Simplify the equation and solve for w, which is 7
Plug into the the length, which is 3w+4
Answer:
Length: 25 inches
Width: 7 inches
Step-by-step explanation:
Perimeter = 2L + 2W
Length: 3w + 4
Width: w
64 = 2(3w + 4) + 2w
64 = 6w + 8 + 2w
64 = 8w + 8
56 = 8w
w = 7
Length: 3(7) + 4 = 25
Width: 7

In a certain city, three newspapers A, B, and C are published. Suppose that 60% of the families in the city subscribe to newspaper A, 40% of the families subscribe to newspaper B, and 30% subscribe to newspaper C. Suppose also that 20% of the families subscribe to both A and B, 10% subscribe to both A and C, 20% subscribe to both B and C, and 5% subscribe to all three newspapers. (i) What percentage of the families in the city subscribe to at least one of the three newspapers? (ii)What percentage of the families in the city subscribe to exactly one newspaper?
Answers
Answer:
(i) = 85%
(ii) = 30%
Step-by-step explanation:
The question is a probability question.
We will need the following values:
P(A) = 60%
P(B) = 40%
P(C) = 30%
P(AnB) = 20%
p(AnC) = 10%
P(BnC) = 20%
P(AnBnC) = 5%
(i) To determine the percentage of the families in the city that subscribe to at least one of the three newspapers:
P(A) + P(B) + P(C) + P(AnBnC) - P(AnB) - p(AnC) - P(BnC)
= 60% + 40% + 30% + 5% - 20% - 10% - 20%
= 85%
(ii) To determine the percentage of the families in the city that subscribe to exactly one newspaper:
P(at least one paper) - p(AnB) - p(AnC) - P(BnC) - P(AnBnC)
= 85% - 20% - 10% - 20% - 5%
= 30%
QUADRATIC EQUATION – WORD PROBLEMS
Fatima got 16 marks more than Zahra in Math test. The product of their mark is 1380. Find their marks.
The answer 30 ,46
I just need the steps
Answers
Answer:
Fatima's points = 46
Zahra's points = 30
Step-by-step explanation:
Let's give names to the unknowns (the number of points each one got)
Fatima's points = y
Zahra's points = x
Now create the equations given by the info they provide:
"Fatima got 16 marks more than Zahra"
y = x + 16
"The product of their mark is 1380."
x * y = 1380
Now use the first equation as substitution for "y" in the second equation:
x * (x + 16) = 1380
reduce the expression:
x^2 + 16 x = 1380
x^2 + 16 x - 1380= 0
Solve using quadratic formula:
[tex]x=\frac{-16+/- \sqrt{16^2+4(1380)} }{2} \\x=\frac{-16+/- \sqrt{5776} }{2} \\x=-8+/- 38\\x = 30\,\,\,or\,\,\,x=-46[/tex]
we pick 30 since the scores from a test must be larger than zero.
Now we use the first equation to solve for the other variable;
y = 30 + 16 = 46
then x = 30 and y = 46

You bought 4 pizzas and paid $7.00 each and cut the pizza into 8 equal slices. You
then sell the slices for $1.75 each. How many pieces would you have to sell to to pay
for the original cost of the 4 pizzas?
Answers
Answer:
You would have to sell
16 slices to pay for the
original price of the 4
pizzas
Step-by-step explanation:
$7.00 a box so you would have to multiply to get to
full price. $7.00x4=$28.00 The full price is $28.00.
If you are selling the slices for $1.75 each you would
also have to divide to know how many slices to sell
to get back to $28.00. 28.00÷1.75=16. So you would
have to sell 16 slices to get back to the full price.
Hope this helps.

decrease 5% by 2205
Answers
Answer:
The answer is,2094.75
Step-by-step explanation:
Percentage decrease = 5% × 2,205
2,205 - Percentage decrease =
2,205 - (5% × 2,205) =
2,205 - 5% × 2,205 =
(1 - 5%) × 2,205 =
(100% - 5%) × 2,205 =
95% × 2,205 =
95 ÷ 100 × 2,205 =
95 × 2,205 ÷ 100 =
209,475 ÷ 100 =
2,094.75
Or to be simpler
You find 5% of 2,205 which is 110.25 then subtract it from 2205 which is 2,094.75 and that 5% of 2,205

If a seed is planted, it has a 70% chance of growing into a healthy plant.
If 8 seeds are planted, what is the probability that exactly 4 don't grow?
Answers
Answer:
Thus, the probability that exactly 4 don't grow is 0.1361 or 13.61%
Step-by-step explanation:
Binomial Distribution
Consider a random experience that has only two possible outcomes: Success or Failure. Let's call p to the probability that the event has a successful outcome and q to the failure outcome.
It follows that p+q=1, or q=1-p.
Now repeat the random experience n times. We want to calculate the probability of getting x successful outcomes. This can be done with the Binomial Distribution formula:
[tex]\displaystyle P_{x} = {n \choose x}\cdot p^{x}\cdot q^{n-x}[/tex]
Where :
[tex]\displaystyle {n \choose x}[/tex]
Is the number of combinations, calcula ted as follows:
[tex]\displaystyle {n \choose x} =_nC_x=\frac{n !}{x ! (n-x) !}[/tex]
A planted seed has a 70% chance of growing into a healthy plant. The successful outcome has p=0.7 and q=0.3.
The experience is repeated n=8 times. We want to calculate the probability of having 4 failures (not growing seeds) or x=4 successes.
Apply the formula:
[tex]\displaystyle P_{4} = {8 \choose 4}\cdot 0.7^{4}\cdot 0.3^{8-4}[/tex]
[tex]\displaystyle P_{4} = 70\cdot 0.7^{4}\cdot 0.3^{4}[/tex]
[tex]\displaystyle P_{4} = 0.1361[/tex]
Thus, the probability that exactly 4 don't grow is 0.1361 or 13.61%

each morning max walks to school. at 8:20, he passes a stoplight that is 2 blocks from home. He reaches the town library at 8:24. At this point, he is 3 blocks from school and halfway there. If Max walks at the same pace all the way to school, at what time does he arrive at school?
Answers
Answer:
8:36
Step-by-step explanation:
If he is at his halfway point at 8:24 and it only took him 4 minutes to get one block in than it would take him 12 minutes to get 3 blocks in and if you add 12 more minutes to the time that he's at right now than he would arrive at 8:36.

For #5 all you have to do is set down to points in order for it to count. The answer is: (0,2) and (3,6)
Step-by-step explanation:
In order to find where exactly you must plot the points, we plug in what we know. In our equation, the 2 is our y intercept, this means that the point is (0,2) (Side Note: here's another example, (0,6) the 6 would be our y intercept)
From the point (0,2) we use the other value given. The other value given in this case, is our slope. When dealing with slope, we use Rise over Run or Rise/Run. This means that from the 2 on the graph, you rise 3 which would be 5 and you run to the right for 4. This now gets you the points (3,6)
Hope this helps with plotting the other questions! :)
(SIDE NOTE: IF THEY GIVE THE VALUE WITH X AS JUST A NUMBER, YOU CAN PLACE A 1 UNDER IT TO TURN IT INTO A FRACTION. FOR EXAMPLE 3X CAN BE TURNED INTO 3/1 WHICH WOULD THEN BE RISE 3 AND RUN 1.
