Answer:
The first term common to both arithmetic sequences: 3
What is the sixth term common to both: 143
Helppppppp show your work
Answer:
No solution
Step-by-step explanation:
x+5x+4=3(2x-1)
First off, rearrange:
6x+4=6x-3
The '6x's cancel out (4=-3, incorrect), which means the equation has no solution.

In Ms. Craig’s class, 75% of the students are boys. There are 18 boys in the class. What is the total number of students in Ms. Craig’s class? |QUICK! IM TIMED
Answer:
24
Step-by-step explanation:
75% of x = 18
75/100 * x = 18 (x = total number of students)
solving
x = 24
total number of students = 24
Checking:
75/100 * 24 = 18

Internet company Gurgle is carrying out testing on the efficiency of its search engine. A sample of 31 searches have been carried out and the time taken to display the results has been recorded for each search. The mean search time for the sample was calculated as 0.2258 seconds. The standard deviation of the search times for the sample was calculated as 0.0188 seconds. The population standard deviation of search times is unknown.
1. Select all the techniques that are commonly used to construct a confidence interval for the mean when the population standard deviation (σ) is unknown:
a. Approximate the population standard deviation (σ) with the sample standard deviation (s)
b. Replace the sample size (n) with n-1
c. Decrease the confidence level to compensate for the increased margin of error
d. Approximate the standard normal distribution with the Student's t distribution
2. Calculate the upper and lower bounds of the 95% confidence interval for the mean search time for the Gurgle search engine.
Answer:
d. Approximate the standard normal distribution with the Student's t distribution
(0.2199 ; 0.2327)
Step-by-step explanation:
Given that :
Sample size, n = 31
Sample mean, xbar = 0.2258
Sample standard deviation, s = 0.0188
Confidence interval (C. I) :
xbar ± margin of error
Margin of Error : Tcritical * s/sqrt(n)
Degree of freedom, df = n - 1 = 31 - 1 = 30
Tcritical value :
T0.05/2, 30 = 2.042
Margin of Error = 2.042 * 0.0188/sqrt(31)
Margin of Error = 0.0068949
C. I = 0.2258 ± 0.0068949
Lower boundary : (0.2258 - 0.006895) = 0.2189
Upper boundary : (0.2258 - 0.006895) = 0.2327
(0.2199 ; 0.2327)
A student translated the phrase below into an algebraic expression, and then evaluated it for g = one-fourth. Is the student’s work correct? one-third more than the product of four and a number; evaluate when g = one-fourth The expression is StartFraction 4 Over g EndFraction + one-third; for g = one-fourth. StartFraction 4 Over 1 EndFraction divided by one-fourth + one-third = StartFraction 4 Over 1 EndFraction times StartFraction 4 Over 1 EndFraction + one-third = 16 + one-third = 16 and one-third. Yes, the student’s work is correct. No, the student divided the fraction incorrectly No, the student made an error when substituting. No, product means multiplication, and the student wrote a division expression.

The question above...
Answer:
I think that its C
Step-by-step explanation:
I think it might be c because the two smaller(11,7) sides must add up to be longer than the longest side(18).And it would be the same length as the longest side,which means you wont be able to construct the triangle. (Eh my explanation wasnt that good but it is what it is)

The Royal Haciendas Resort in Playa del Carmen, Mexico, is thinking of starting a new promotion. When a customer checks out of the resort after spending 5 or more days, the customer would be given a voucher that is good for 2 free nights on the next stay of 5 or more nights at the resort. The marketing manager is interested in estimating the proportion of customers who return after getting a voucher. From a simple random sample of 100 customers, 62 returned within 1 year after receiving the voucher. Please determine the 95% confidence interval estimate of the true population proportion.
Answer:
The 95% confidence interval estimate of the true population proportion is (0.5249, 0.7151).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
From a simple random sample of 100 customers, 62 returned within 1 year after receiving the voucher.
This means that [tex]n = 100, \pi = \frac{62}{100} = 0.62[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.62 - 1.96\sqrt{\frac{0.62*0.38}{100}} = 0.5249[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.62 + 1.96\sqrt{\frac{0.62*0.38}{100}} = 0.7151[/tex]
The 95% confidence interval estimate of the true population proportion is (0.5249, 0.7151).

Step-by-step explanation:
(Assuming the paper goes around the side of the tin only and not the top/bottom)
Imagine the net of this can. It is a cylinder, so it would consist of a rectangle and two circles, the surface area of this rectangle is what we're being asked for.
The length and width of the rectangle are needed to find the area, (area of a rectangle=length*width). The width is marked as 3in. The length is equal to the circumference of the circle (with radius 2in):
Circumference=2πr
=2π(2)
=12.5663706144=length
Area=width*length
=3*12.5663706144
=37.6991118431
≈37.7in²
Find the value of X and Y
Answer: x=2 y=152
Step-by-step explanation:
9x + 10 = 15x - 2 They are corresponding angles.
9x = 15x - 12 [Subtract 10 from the both side]
-6x = -12 [Subtract 15x from both side]
x = 2 [Divide -6 from both side]
(9x + 10) + y = 180
[9(2) + 10] + y = 180
28 + y = 180
y = 152

A can in the shape of a cylinder has a diameter of 6 centimeters and a height of 10 centimeters. Which measurement is donest to the total suratace area
of the can in square centimeters?
Answer:
radius r = 3 cm
height h = 10 cm
volume V = 282.743339 cm^3
lateral surface area L = 188.495559 cm^2
top surface area T = 28.2743339 cm^2
base surface area B = 28.2743339 cm^2
total surface area A = 245.044227 cm^2
In Terms of Pi π
volume V = 90 π cm3
lateral surface area L = 60 π cm^2
top surface area T = 9 π cm^2
base surface area B = 9 π cm^2
total surface area A = 78 π cm^2
Step-by-step explanation:
Agenda:
r = radius
h = height
V = volume
L = lateral surface area
T = top surface area
B = base surface area
A = total surface area
π = pi = 3.1415926535898
√ = square root
Formluas:
Cylinder Formulas in terms of r and h:
Calculate volume of a cylinder:
V = πr2h
Calculate the lateral surface area of a cylinder (just the curved outside)**:
L = 2πrh
Calculate the top and bottom surface area of a cylinder (2 circles):
T = B = πr2
Total surface area of a closed cylinder is:
A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Houa has an action figure collection. She keeps some in a display case and the rest on
the wall. 82 of her action figures are on the wall, and 59% of her action figures are in the display case. What is the total number of action figures in Houa's collection?
Answer:
200 action figures
Step-by-step explanation:
Given
[tex]Wall = 82[/tex]
[tex]Display\ Case = 59\%[/tex]
Required
Total action films
If 59% is on a display case, then 4!% is on the wall. Let the total be x.
So, we have:
[tex]Wall = 41\% * x[/tex]
Substitute 82 for Wall
[tex]82= 41\% * x[/tex]
[tex]82= 0.41 * x[/tex]
[tex]200= x[/tex]
[tex]x = 200[/tex]
