The Dimensions of the wall are given as:
8ft × 5ft = 40ft² or 40 square feet
Step-by-step explanation:
Answer:
24 minutes
Step-by-step explanation:
8 * 5 = 40 ft²
---------------------------
Method I: Use a proportion
x/40 = 45/75
multiply both sides by 40
x = 45/75 * 40
x = 24
24 minutes
---------------------------
Method II: Use the rate
45/75 = 0.6min/ft²
40 * 0.6 = 24

Which of the following choices can be considered binomial random variables?
Choose all answers that apply:
A
A container holds 100 pens, half of which are red. Select an SRS of 5 pens and let R= the
number of red pens obtained.
в)
A container holds 1000 pens, half of which are red. Select an SRS of 5 pens and let S = the
number of red pens obtained.
A container holds 20 pens, half of which are red. Select an SRS of 5 pens and let Q = the
number of red pens obtained.
Answer: A and B
Step-by-step explanation:
Q isn’t a binomial since the pens are being selected without replacement and the sample size is more than 10% of the population size, so the trails are not independent.
A binomial random variable is such that can take either of two possibilities at the same time.
Samples R and S can be considered as binomial random variables
For a random variable to be considered a binomial random variable, the population must be at least ten times the sample size.
So, we have the following highlights
Container A
[tex]n =100[/tex]
[tex]x = 5[/tex]
Divide n by x
[tex]\frac nx = \frac{100}{5}[/tex]
[tex]\frac nx = 20[/tex]
This means that the population is 20 times the sample size.
Hence, R is a binomial random variable.
Container B
[tex]n =1000[/tex]
[tex]x = 5[/tex]
Divide n by x
[tex]\frac nx = \frac{1000}{5}[/tex]
[tex]\frac nx = 200[/tex]
This means that the population is 200 times the sample size.
Hence, S is a binomial random variable.
Container C
[tex]n =20[/tex]
[tex]x = 5[/tex]
Divide n by x
[tex]\frac nx = \frac{20}{5}[/tex]
[tex]\frac nx = 4[/tex]
This means that the population is 4 times the sample size.
Hence, Q is not a binomial random variable.

The triangle is an equilateral, so you can use the same formula on each side.
1.5x x 3 = 4.5x
5 x 3 = 15
Find the equation of the tangent at the point (1.1) for the function Y given in the equation
xy^2 + y = 2x
If y = y(x), then the slope of the tangent line to (1, 1) is equal to the value of the derivative dy/dx when x = 1 and y = 1.
Compute the derivative using implicit differentiation:
d/dx [xy ^2 + y] = d/dx [2x]
d/dx [xy ^2] + d/dx [y] = 2 d/dx [x]
(x d/dx [y ^2] + d/dx [x] y ^2) + dy/dx = 2
2xy dy/dx + y ^2 + dy/dx = 2
(2xy + 1) dy/dx = 2 - y ^2
dy/dx = (2 - y ^2) / (2xy + 1)
Plug in x = 1 and y = 1 :
slope = dy/dx = (2 - 1^2) / (2*1*1 + 1) = 1/3
Now use the point-slope formula to get the equation of the line:
y - 1 = 1/3 (x - 1)
y = x/3 + 2/3

Solve for x. Need it by today.
Alright, so a circle is 360 degrees. We know there's an arc of 90 and an angle extending from the radius being 125.
Since the given angle extending from the radius is at the radius, there will also be a 125 degree arc at the circumference of the circle there.
With this, do:
360-90-125 = 145
to get the amount of arc in the unknown area.
Still though, we need to find the x value, so get the unknown value and set it equal to 145.
16x + 1 = 145
16x + 1-1 = 145-1
16x=145
x = 9.0625 or 9 1/16
Hope that helps.

Answer:
x = (1/4) +(1/8)e^2
Step-by-step explanation:
Undo what is done to x.
4ln(8x-2) +2 = 10
4ln(8x -2) = 8 . . . . . . . subtract 2
ln(8x -2) = 2 . . . . . . . . divide by 4
8x -2 = e^2 . . . . . . . . . take antilogs
8x = 2 +e^2 . . . . . . . . add 2
x = (2 +e^2)/8 . . . . . . divide by 8
x = (1/4) +(1/8)e^2

Under her cell phone plan, Rajani pays a flat cost of $65 per month and $5 per gigabyte. She wants to keep her bill under $85 per month. Write and solve an inequality which can be used to determine gg, the number of gigabytes Rajani can use while staying within her budget.
Answer:
gg ≤ 4
Step-by-step explanation:
Total cost(gg) = $65 + ($5/mo)(gg) = $85
Ths reduced to $85 - $65 = ($5/mo)(gg), which returns gg = 4
The correct answer is an inequality: gg ≤ 4

-7, -3, 1, 5 what is the explicit formula
Answer:
f(x)=4x-11
Step-by-step explanation:
This is a linear sequence, so we have to find our common difference, or slope, by finding the difference between any term and its previous term. We should do this a couple of times to make sure it's consistent. In this case, our slope is 4 and our first term is -7. We can do our equation in slope intercept (y=mx+b) form. However, to do this, we have to find the '0'th' term, or the term where x=0, a.k.a. the y-intercept. Our 1st term where x-1 is -7, and since our common difference is 4, we subtract 4 from negative 7 to get a y-intercept of -11. Our equation is now y=4x-11. To make this an explicit formula, we convert into f(x) form to get a formula of f(x)=4x-11.
Which equation represents the data in this function table?
A. y = x + 4
B. y = x - 4
C. y = 4x
D. x = y + 3
Answer:
A.
Step-by-step explanation:
If you put the x value of the table and use it in each equation, only one gives the y output on the table.
y=x + 4
5=1 + 4
6=2+4
7=3+4
8=4+4
9=5+4
The correct option is A) y=x+4
What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given here option A as y=x+4 now lets verify this option
if x=1 then y = 1+4
= 5
Again if x=2 then y =2+4
=6
Similarly it can be clearly observed that all the values of y are 4 greater than the input of x given in the table.
Hence, option A is the correct answer.
