Hello! answer: 16
Step-by-step explanation:
These are a bit different instead your solving for B so you have to work backwords so... 20 × 20 = 400 12 × 12 = 144 400 - 144 = 256 now we just find out what multiplied by itself = 256 16 × 16 = 256 therefore b = 16 Hope that helps!

Find the equation of a straight
line passing through the point of
intersection of the lines
y = 2x +3 and x +y = 3 and
parallel to the line y = -5x +7
Answer:
y = -5x + 3.
Step-by-step explanation:
We can find the point of intersection by solving the system:
y = 2x + 3 .... 1
x + y = 3 ...... 2 from this:
y = 3 - x ....... .3
Equating equations 1 and 3:
2x + 3 = 3 - x
3x = 0
x = 0 so y = 2(0) + 3 = 3.
So the point of intersection is (0, 3).
So the required equation has slope -5 and passes through (0, 3) and, using the point-slope form of a straight line, we have:
y - 3 = -5(x - 0)
y - 3 = -5x
y = -5x + 3.

I have an average of 84 right now but I failed my homework so that would most likely turn to an 82 and my parents will actually kill me I need to get to at least an average of 90 minimum I know report cards will be out soon and I will guess I have a week before marking period three ends could I boost my average up by 6-8% within a week of getting straight hundreds in my homework? Homework’s count a lot.
Answer:
I would say yes. Now I'm not in your type of school grading system, but if you try to get as many 90s and 100s in your homework for the next week, you would probably get there.

If a customer rolls the dice and rents a second movie every Thursday for 30 consecutive weeks, what is the approximate probability that the total amount paid for these second movies will exceed $15.00?
Complete Question:
Every Thursday, Matt and Dave's Video Venture has "roll-the-dice" day. A customer may choose to roll two fair dice and rent a second movie for an amount (in cents) equal to the numbers uppermost on the dice, with the larger number first. For example, if the customer rolls a two and a four, a second movie may be rented for $0.42. If a two and a two are rolled, a second movie may be rented for $0.22. Let X represent the amount paid for a second movie on roll-the-dice day. The expected value of X is $0.47 and the standard deviation of X is $0.15
Answer:
0.14
Step-by-step explanation:
Given that :
Expected value = 0.47
Standard deviation = 0.15
Sample size, n = 30
The mean = expected value * sample size
Mean = 0.47 * 30 = 14.1
Standard deviation of sample = σ / √n
0.15 = σ/√30
σ = 0.8216
P(x > 15) :
Z = (x - mean) /standard deviation
Z = (15 - 14.1) / 0.8216 = 1.095
P(Z > 1.095) = 0.1367
P(Z > 1.095) = 0.14
The axis of symmetry for the graph of the function f(x)=3x2+bx+4 is What is the value
of b?
-18

18
Answer:
B.) -9
Step-by-step explanation:
The value of b if 3/2 is the axis of symmetry for the graph of the function f(x)=3x2+bx+4 is -9
How to calculate the axis of symmetry of a function?The standard equation of a function in vertex form is given as:
f(x) = (a + x)^2 + h
Given the function f(x)=3x^2+bx+4 with an axis of symmetry of 3/2, the vertex is expressed as:
3/2= -b/2a
-b/2(3)=3/2
-b/6=3/2
Cross multiply
-2b = 18
-b=9
Hence the value of b if 3/2 is the axis of symmetry for the graph of the function f(x)=3x2+bx+4 is -9

Kevin is paid $8.80 per hour. He worked 7 hours. He gave his mother 1/4 of his earnings. How much did Kevin have left?
Question 2 options:
25%
$46.20
$15.40
$61.60
Question 31poins
Answer:
46.20
Step-by-step explanation:
First determine how much he earned:
8.8 per hour times 7 hours
8.80 *7 =61.60
Then determine how much he gave his mother
61.60 * 1/4 =15.4
Subtract this from the total amount to determine how much is left
61.60-15.40
46.20

Answer:
"The expression represents a cubic polynomial with 3 terms. The constant term is -10, the leading degree is 3, and the leading coefficient is (-1/6)"
Step-by-step explanation:
We have the expression:
[tex]-\frac{x^3}{6} - 10 + x[/tex]
First, what does that expression represents?
As al the powers of x are positive numbers, we can see that this is a polynomial, and the largest power is 3, so this is a polynomial of degree 3, also called a cubic polynomial.
How many terms are there?
The terms are the things separated by + or - symbols, is easy to see that there are 3 terms.
What is the constant term?
The constant term is the term where the variable, x, does not appear, here the constant term is: -10
What is the leading coefficient?
The leading coefficient is the coefficient that multiplies the term with the largest power of x, in this case, we can rewrite:
[tex]-\frac{x^3}{6} -10 + x = (\frac{-1}{6})*x^3 - 10 + x[/tex]
the leading coefficient is:
(-1/6)
There is a part of the statement that I can't read, i suppose that there says:
"leading degree"
this is just the largest power of x that appears in the polynomial, in this case, is 3.
Then the complete statement is:
"The expression represents a cubic polynomial with 3 terms. The constant term is -10, the leading degree is 3, and the leading coefficient is (-1/6)"
The Ace Bicycle Shop charges a flat fee
of $4, plus $1 per hour, for the hire of a
bicycle. The Best Bicycle Shop charges
a flat fee of $8, plus 50 cents per hour.
Connie and her friends hire three bicycles
from Ace, and David and his brother hire
two bicycles from Best. After how many
hours will their hire costs be the same?
Answer:
x = number of hours = 8 hours
Step-by-step explanation:
Let
x = number of hours
There are 3 people who rented bicycle from each shop
Ace bicycle shop:
Total cost = 3(4 + x)
= 12 + 3x
Best bicycle shop:
Total cost = 3(8 + 0.50x)
= 24 + 1.5x
Equate both equations and solve
12 + 3x = 24 + 1.5x
12 - 24 = 1.5x - 3x
-12 = -1.5x
x = -12/-1.5
x = 8 hours
x = number of hours = 8 hours

In Mr. Forester's science class,
students are given five tests in a
semester. Latoya's scores on the first
four tests are 86%, 82%, 91%, and
98%. If Latoya's score on the final
test is represented by x, then her
class average y can be found using
the equation below.
y =
86% + 82% + 91% + 98% + x
5
Mr. Forester awards an "A" to any
student whose class average falls
within the 90 - 100% range. Which
interval represents the domain of final
test scores that Latoya can get and
still receive an "A"?
F [90%, 100%]
G [87%, 100%]
H [93%, 100%]
[96%, 100%]
Answer:
The answer is "H [93%, 100%]"
Step-by-step explanation:
I'll edit this in a second to show the process, but it may take a minute. Just have the answer for now.
This is a surprisingly useful question hah, I'll bet many will need to do this.
This question is just finding the average. Pretty simple.
y = 86 + 82 + 91 + 98 + x / 5
y = 357 + x / 5
An easy way is to do the lowest question first, then go from lowest to second lowest and so on. Because if you go to the highest one and the answer is one of the lower ones, well, of course it's going to be within the 90-100 range, but that doesn't necessarily mean it's the answer.
y = 357 + (87) / 5
y = 444 / 5
y = 88.8
Okay, so the answer isn't G. Then let's try H.
y = 357 + (93) / 5
y = 450 / 5
y = 90
Yep, the answer is H. This is because it equals 90, which is indicative of the 90-100% range that Latoya needs to get an "A".
There are two bags of oranges on sale. The prices are shown below: Bag A: $2400 containing 12 oranges Bag B: $3000 containing 20 oranges Which is the better buy?
Answer:
Bag B which is $150 for one orange
Step-by-step explanation:
In ,bag A 12 oranges cost 2400
The price of one orange in bag A is
= 2400/12
= $200
In bag B 20 oranges cost $3000
The cost of one orange in bag B is
= 3000/20
= $150
Hence the better buy is bag B which goes for $150 for one orange

Answer:
3 is for green marbles
21 is the total of all marbles
Step-by-step explanation:
you only have 1 event so I think we don't need some formula or something
the formula is this if the event A and B has no intersection P( A U B)= P(A)+P(B)
and if it has intersection, the formula is like this P( A ∩ B)=P(A)+P(B)-P( A ∩ B)
