Hope it helps you correct me if i am wrongFind the number of sides of a regular polygon if the sum of the interior angles of the
polygon is 7020
Answer:
n = 6
Step-by-step explanation:
Given the following data;
Sum of interior angles, S = 720°
Mathematically, the sum of the interior angles in a regular polygon is given by the formula;
S = 180(n - 2)
Where;
n is the number of sides.
S is the sim of the interior angles
720 = 180(n - 2)
720 = 180n - 360
180n = 720 + 360
180n = 1080
n = 6
find the mean and median of these data: 2, 7, 13, 15, 17, 19
Pls Pls answer and HURRY
Answer:
Mean: 12.166
Median: 14
Step-by-step explanation:
Answer:
mean: 73 ÷ 6 (amount of numbers in the list) = 12.166
median (middle number): 14
Step-by-step explanation:
to find the mean (average) you add all the numbers in the list and divide by the numbers there are (6 in the above problem)
2+7+13+15+17+18 = 73÷6 = 12.16
Jonah wants to construct a confidence interval using 90% confidence to estimate what proportion of silicon wafers at his factory is defective. He wants the margin of error to be no more than 3%. A previous study suggests that about 6% of these wafers are defective. If we assume p=0.06, what is the smallest sample size required to obtain the desired margin of error? 234 416 170 936
Answer:
170
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].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
Assume:
[tex]\pi = 0.06[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
What is the smallest sample size required to obtain the desired margin of error?
This is n for which M = 0.03. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.645\sqrt{\frac{0.06*0.94}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.645\sqrt{0.06*0.94}[/tex]
[tex]\sqrt{n} = \frac{1.645\sqrt{0.06*0.94}}{0.03}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.645\sqrt{0.06*0.94}}{0.03})^2[/tex]
[tex]n = 169.6[/tex]
Rounding up, 170.

A small orchard is made up of 12 trees that all together produce 72 apples.
Which of the following is the best estimate of how many apples each tree
produces?
3 apples per tree
15 apples per tree
12 apples per tree
7 apples per tree
17 apples per tree
Step-by-step explanation:
12 trees produce 72 apples
1 tree pruduces 72/12 apples
or 6 apples per tree
estimated => 7 apples per tree
A small orchard is made up of 12 trees that all together produce 72 apples. Which of the following is the best estimate of how many apples each tree produces?
3 apples per tree
15 apples per tree
12 apples per tree
7 apples per tree
17 apples per tree
____________________Solution :-Given Information :-Number of trees ➢ 12Apples produced by all 12 trees ➢ 72To Find :-Which of the following is the best estimate of how many apples each tree produces?
3 apples per tree
15 apples per tree
12 apples per tree
7 apples per tree
17 apples per tree
Calculation :-Here, We will simply divide the number of apples produced by 12 trees by the number of trees and then we will round it off to it's nearest 'ones' place.
⇒ Total number of apples each tree produces = [tex] \sf \frac{total \: number \: of \: apples}{total \: number \: of \: trees} [/tex]
Substituting the values given, We get,
⇒ Total number of apples each tree produce = [tex] \sf \frac{72}{12} [/tex]
⇒ Total number of apples each tree produces = 6
Now, when we round it off to it's nearest 'ones' place, We get,
⇒ Round off 6 = 7
Since, We can see that, 4th option from the list of option given, is 7. Therefore 7 is the answer.
____________________Final Answer :-4th option :- 7 apples per tree is the correct answer.____________________Write an inequality for the graph below.

If the first term (a) is 4 and the common ratio (r) is 0.9, then the sequence diverges. Then the correct option is D.
What is a geometric sequence?Suppose the initial term of a geometric sequence is a
and the term by which we multiply the previous term to get the next term is r
Then the sequence would look like
a, ar, ar², ar³, ...
The sequence is given below.
[tex]\rm a_n = 4 (0.9)^n[/tex]
Then the sum of the sequence will be given as
The first term (a) is 4. And the common ratio (r) is 0.9.
Then we get
[tex]\rm S_n = \dfrac{a (1 - r ^n)}{ (1 - r)}\\\\\rm S_n = \dfrac{4 (1 - 0.9 ^n)}{ (1 - 0.9)}\\\\\rm S_n = \dfrac{4 (1 - 0.9 ^n)}{0.1}\\\\\rm S_n = 40 (1 - 0.9^n)[/tex]
For n = 1, we have
S₁ = 40 (1 - 0.9)
S₁ = 40 x 0.1
S₁ = 4
For n = 2, we have
S₂ = 40 (1 - 0.9²)
S₂ = 40 x 0.19
S₂ = 7.6
For n = 3, we have
S₃ = 40 (1 - 0.9³)
S₃ = 40 x 0.271
S₃ = 10.84
If the common ratio is less than one then the sequence will diverge.

Step-by-step explanation:
Babies born after 40 weeks gestation have a mean length of 52.2 centimeters (about 20.6 inches). Babies born one month early have a mean length of 47.4 cm. Assume both standard deviations are 2.5 cm. and the distributions are unimodal and symmetric. a. Find the standardized score (z-score), relative to all U.S. births, for a baby with a birth length of 45 cm. b. Find the standardized score of a birth length of 45 cm. for babies born one month early, using 47.4 as the mean. c. For which group is a birth length of 45 cm more common
Answer:
a) [tex]Z = -2.88[/tex]
b) [tex]Z = -0.96[/tex]
c) 40 weeks gestation babies
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
a. Find the standardized score (z-score), relative to all U.S. births, for a baby with a birth length of 45 cm.
Here, we use [tex]\mu = 52.2, \sigma = 2.5[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{45 - 52.2}{2.5}[/tex]
[tex]Z = -2.88[/tex]
b. Find the standardized score of a birth length of 45 cm. for babies born one month early, using 47.4 as the mean.
Here, we use [tex]\mu = 47.4, \sigma = 2.5[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{45 - 47.4}{2.5}[/tex]
[tex]Z = -0.96[/tex]
c. For which group is a birth length of 45 cm more common?
For each group, the probability is 1 subtracted by the pvalue of Z.
Z = -2.88 has a lower pvalue than Z = -0.96, so for Z = -2.88 the probability 1 - pvalue of Z will be greater. This means that for 40 weeks gestation babies a birth length of 45 cm is more common.

sundip and emma have some money
the ratio of sundips money to emmas money is 3:5

the ratio of sundips money to emmas money is now 2:3
found how much money sundip has
Answer:
Step-by-step explanation:
Can you please answer the Sundip Ratio question?
£180.00
The amount of money Sundip have £ 2700.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
ratio of sundips money : emmas money = 3:5
emma spends £450
ratio of sundips money : emmas money = 2:3
So, Sundip have money = 3x and Emma have money = 5x.
Now, Emma spends £450.
then she is left = (5x-450).
Now, the ratio of Sundip's money to Emma's money is given as 2:3 = 2/3.
2/3 = 3x/(5x-450).
2(5x-450) = 3*3x
10x - 900 = 9x
x = 900.
Thus, Sundip have 3x = 3 x 900 = 2700.
