Answer:
SA;
Area that will be covered with blue paint = 486 ft²
Step-by-step explanation:
✔️The four walls of Frank's room is to be covered with blue paint, therefore, it is a Surface area (SA) problem.
✔️Solve:
The number of square feet to be covered with blue paint = the surface area of the 4 faces
✔️Two of the faces have the following equal dimensions:
Length = 15 ft; height = 9ft
Surface area of the two faces = 2(15*9)
= 270 ft²
✔️The other two faces have the following equal dimensions:
Length = 12 ft, height = 9 ft
S.A = 2(12*9)
S.A = 216 ft²
Total area of the wall to be covered with blue paint = 270 + 216 = 486 ft²
find the volume of the cynlinder.
Answer:
Step-by-step explanation:
Volume of the cylinder = volume of the outer cylinder - volume of the inner cylinder
volume of the inner cylinder = πr2h
r = 1
h = 6
Volume = 18.85
Volume of outer cylinder = πr2h
r = 6/2 = 3
h = 6
volume = 169.65
Volume of the desired cylinder = 169.65 - 18.85 = 150.8

if a dress costs $27,000 when it is on sale for 10% off, what is its original cost?
Answer:
30,000
Step-by-step explanation:
10% of 30,000 is 3,000
30,000 - 3,000 = 27,000
Find an equation for the line with the given properties. Express your answer using either the general form or the slope-intercept form of the equation of a line. Parallel to the line ; containing the point (0,0)
Answer:
y = 7x
Step-by-step explanation:
Complete question:
Find an equation for the line with the given properties. Parallel to the line 7x - y = -7; containing the point (0,0)
The equation of a line in point-slope form is expressed as;
y - y0 = m(x-x0)
(x0, y0) = (0,0)
Given the equation of the line as 7x - y = -7;
Rewrite and get the slope
-y = -7x - 7
y = 7x+7
Get the slope
mx = 7x
m = 7
Substitute into the equation
y - 0 = 7(x - 0)
y = 7x
Hence the required equation is y = 7x

Which equation, when graphed, has x-intercepts at (−1, 0) and (−5, 0) and a y-intercept at (0, −30)?
Answer:
y = -6x^2 - 36x - 30
Step-by-step explanation:
X intercepts are the roots
y = a(x + 1)(x + 5)
to find "a" use point (0, -30)
-30 = a(1)(5)
-30 = a(5)
a = -6
therefor
y = -6(x + 1)(x + 5)
Expanded form
y = -6x^2 - 36x - 30

What is the probability that a customer ordered
a medium given that he or she ordered a hot
drink?
Rounded to the nearest percent, [? ]%
Answer:
48%
Step-by-step explanation:
48/100 = 48%
Edit: the awnser is 64% because 48/75 = 64%
The probability that a customer ordered a medium given that he or she ordered a hot drink is,
⇒ 48%
What is mean by Probability?
The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
At a coffee shop, the first 100 customers orders were as given.
Now,
Total customer = 100
Order hot median coffee = 48
Thus, The probability that a customer ordered a medium given that he or she ordered a hot drink is,
⇒ 48 / 100
⇒ 0.48
⇒ 48%
Thus, The probability that a customer ordered a medium given that he or she ordered a hot drink is,
⇒ 48%

12. Each section of the line on each side is identical (shown by the marks through each line)
This means both those angles are also the same.
6x + 1 = 9x-23
Add 23 to both sides
6x + 24 = 9x
Subtract 6x from both sides
24 = 3x
Divide both sides by 3
X = 8
13. Both angles when added together need to equal 180
5x-24 + 8x +9 = 180
Combine like terms
13x -15 = 180
Add 15 to both sides
13x = 195

Answer:
The nth term is 35+ 7(n-1) or can be written 28 + 7n
Step-by-step explanation:
This is an arithmetic sequence, where each term equals the previous term, with a constant value added.
T1 = 35
T2 = 42 = T1 + 7 = 35 + 7
T3 = 49 = T2+ 7 = 35 + 7 + 7 = 35 + 2x7
…
The nth term is equal to 35 + 7X(n-1)
An article presents a study of the failure pressures of roof panels. A sample of 15 panels constructed with 8-inch nail spacing on the intermediate framing members had a mean failure pressure of 8.48 kPa with a standard deviation of 0.96 kPa. A sample of 15 panels constructed with 6-inch nail spacing on the intermediate framing members had a mean failure pressure of 9.93 kPa with a standard deviation of 1.02 kPa. Can you conclude that 6-inch spacing provides a higher mean failure pressure
Answer:
There is sufficient evidence to conclude that six inches spacing has a higher mean failure pressure than 8 inches
Reject [tex]H_0\ at\ 5%[/tex] level of significance
Step-by-step explanation:
From the question we are told that:
Sample size 1 [tex]n_1=15[/tex]
Spacing 1 [tex]s_1=8[/tex]
Mean 1 [tex]\=x_1=8.48[/tex]
Standard deviation 1 [tex]\sigma_1=0.96 kPa[/tex]
Sample size 2 [tex]n_2=16[/tex]
Spacing 2 [tex]s_2=6[/tex]
Mean 1 [tex]\=x_1=9.93[/tex]
Standard deviation 1[tex]\sigma_1=1.02 kPa[/tex]
Generally the hypothesis is mathematically given as
Null [tex]H_0:\mu_1-\mu_2[/tex]
Alternative [tex]H_a:\mu_1\mu_2[/tex]
Generally the equation for pooled estimate is mathematically given by
[tex]S=\sqrt{\frac{(n_1-1)\sigma_1^2+(n_2-1)\sigma_2^2}{n_1+n_2-2} }[/tex]
Therefore
[tex]S=\sqrt{\frac{(15-1)0.96^2+(16-1)1.02^2}{15+15-2} }[/tex]
[tex]S=0.9905[/tex]
Generally the equation for test statistics is mathematically given by
[tex]t=\frac{\=x_1+\=x_2}{S\sqrt{\frac{1}{n _1}+\frac{1}{n_2}}}[/tex]
[tex]t=\frac{\=8.48-9.93}{0.9905\sqrt{\frac{1}{15}+\frac{1}{15}}}[/tex]
[tex]t=-4.00091[/tex]
Therefore From table
[tex]P value=P(t_{15+15-2}=4.00091)[/tex]
[tex]P value=0.00041918[/tex]
[tex]P<0.0005[/tex]
Therefore
There is sufficient evidence to conclude that six inches spacing has a higher mean failure pressure than 8 inches

Which divisor of x3 + 3x2 - 16x - 48 has a remainder of zero?
A. X + 2
B. X-4
C. x-3
D. x + 8
I need this one ASAP
===========================================================
Explanation:
We'll use the remainder theorem.
This theorem says that if you divide p(x) over (x-k), then the remainder is p(k).
We have p(x) = x^3 + 3x^2 - 16x - 48 and the denominator is one of the four choices A through D.
Let's go through each of them until we find the answer.
-----------------
For choice A, we have x+2 which is the same as x-(-2). It matches with x-k to show that k = -2.
Plug k = -2 into p(x) to get
p(x) = x^3 + 3x^2 - 16x - 48
p(-2) = (-2)^3 + 3(-2)^2 - 16(-2) - 48
p(-2) = -12
The remainder is -12, which is not 0 like we're after. We can cross A off the list.
-----------------
We'll follow the same ideas for choices B through D
For choice B, we plug in k = 4 because x-4 matches with x-k to show that k = 4.
p(x) = x^3 + 3x^2 - 16x - 48
p(4) = (4)^3 + 3(4)^2 - 16(4) - 48
p(4) = 0
We end up with a remainder of 0, so we can stop here. Dividing (x^3+3x^2-16x-48) all over (x-4) leads to some quotient and a remainder of 0.
Put another way: (x-4) is a factor of x^3+3x^2-16x-48
-----------------
Side notes:
x^3+3x^2-16x-48 factors to (x-4)(x+4)(x+3)If you try out choice C, the remainder is -42The remainder for choice D is -240 (you'll use k = -8).Will give brainleist please. Help ±
