Answer:
58%56%Step-by-step explanation:
a) Number of girls:
23 + 64 = 87Percentage:
87/150*100% = 58%b) Number of students prefer watching TV:
64 + 20 = 84Percentage:
84/150*100% = 56%Answer:
no of percentage of girls=no of girls/total ×100%
=87/150×100%=58%
percentage of the students prefer watching TV
=total no the students prefer watching TV/total std.×100%
=84/150×100%=56%

Find the area of a regular 15-gon with radius 64 mm
Answer:
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.
Step-by-step explanation:
A machine, when working properly, produces 5% or less defective items. Whenever the machine produces significantly greater than 5% defective items, it needs repair. A random sample of 300 items taken from the production line contained 27 defective items. Test at the 1% significance level if the percentage of defective items produced by this machine is greater than 5%.
Answer:
The pvalue of the test is 0.0007 < 0.01, which means that we reject the null hypothesis and accept the alternate hypothesis that the percentage of defective items produced by this machine is greater than 5%.
Step-by-step explanation:
A machine, when working properly, produces 5% or less defective items.
This means that the null hypothesis is:
[tex]H_0: p \leq 0.05[/tex]
Test if the percentage of defective items produced by this machine is greater than 5%.
This means that the alternate hypothesis is:
[tex]H_a: p > 0.05[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.05 is tested at the null hypothesis:
This means that [tex]\mu = 0.05, \sigma = \sqrt{0.05*0.95}[/tex]
A random sample of 300 items taken from the production line contained 27 defective items.
This means that [tex]n = 300, X = \frac{27}{300} = 0.09[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.09 - 0.05}{\frac{\sqrt{0.05*0.95}}{\sqrt{300}}}[/tex]
[tex]z = 3.18[/tex]
Pvalue of the test:
Testing if the mean is greater than a value, which means that the pvalue of the test is 1 subtracted by the pvalue of Z = 3.18, which is the probability of a finding a sample proportion of 0.09 or higher.
Looking at the Z-table, Z = 3.18 has a pvalue of 0.9993
1 - 0.9993 = 0.0007
The pvalue of the test is 0.0007 < 0.01, which means that we reject the null hypothesis and accept the alternate hypothesis that the percentage of defective items produced by this machine is greater than 5%.

x ≥ 12
Answer:
12
Step-by-step explanation:
solve the equation px=27
I assume that you want to solve for x.
If so, just divide both sides by p.
px/p = 27/p
x = 27/p

c. x-3y=6
d. 3x + 2y=6
PLEASE HELP TYYY!
y = 4x-9
y = x-3
Which method and why? Solve, shoving all work
Answer:
(2,-1)
Step-by-step explanation:
The ys in both questions are isolated on one side of the equation in both. The numerical coefficient of both is 1. Therefore you should equate the the left side of each equation to the other left side. The solution is the easiest one to solve because there is only 1 unknown on both sides.
4x - 9 = x - 3 Subtract x from both sides.
4x-x - 9 = -3 Combine
3x -9 = - 3 Add 9 to both sides
3x - 9+9 = - 3+9
3x = 6 Divide by 3
3x/3 = 6/3
x = 2
===============
Now use the second equation to solve for y
y = x - 3
y = 2 - 3
y = -1
==============
The solution is (2,-1)

- Seats in a theater are curved from the front row to the back. The front row has 10 chairs, the second has 16 and the third has 22, and so on.
a) Write a recursive rule for this series:
b) Write an explicit rule for this series:
c) Using the explicit formula, find the number of chairs in row 5 (show work)
d) The auditorium can hold 17 rows of chairs. Write a sigma notation for this series, and then use either series formula to calculate how many chairs can fit in the auditorium.
Answer:
The series:
10, 16, 22, ...This is an AP with the first term a₁ = 10 and common difference d = 6
a) Recursive formula:
a₁ = 10,aₙ = aₙ₋₁ + 6b) Explicit formula:
aₙ = a₁ + 6(n - 1) ⇒ aₙ = 10 + 6n - 6 ⇒ aₙ = 6n + 4c) n = 5 ⇒ a₅ = ?
a₅ = 6*5 + 4 = 34d) S₁₇ = ?
Sₙ = n(a₁ + aₙ)/2 = n(2a₁ + (n - 1)d)/2S₁₇ = 17(2*10 + 16*6)/2 = 986Step-by-step explanation:
sn=15+(n-1)2
the 20th row n=20 so the seats are
15+(20-1)(2)=53 seats
Explicit formula:
aₙ = a₁ + 6(n - 1) ⇒ aₙ = 10 + 6n - 6 ⇒ aₙ = 6n + 4

The Ferris wheel at the State Fair of Texas is 450 feet across the center. How many feet would a person travel if they rode around the ferris wheel 6 times? PLEASE give a explanation
Answer:
the number of feet in the case when the person rode around the ferris wheel is 2,700 feet
Step-by-step explanation:
The number of feet in the case when the person rode around the ferris wheel is shown below:
Given that
There is 450 feet across the center
And, it is 6 times rounded
So, the number of feet is
= 450 × 6
= 2,700 feet
Hence, the number of feet in the case when the person rode around the ferris wheel is 2,700 feet
