The given histogram is uniform histogram.
Since we know that,
A histogram is a graphical depiction of data distribution in statistics. The histogram is represented by a series of neighboring rectangles, with each bar representing a different type of data.
Statistics is a branch of mathematics that is used in a variety of areas. When numbers are repeated in statistical data, this repetition is known as Frequency, and it may be put down in the form of a table, which is known as a frequency distribution.
A Frequency distribution may be represented graphically using several types of graphs, one of which is a Histogram.
Based on the frequency distribution of the data, the histogram may be categorised into distinct categories. Normal distribution, skewed distribution, bimodal distribution, multimodal distribution, comb distribution, edge peak distribution, dog food distribution, heart cut distribution, and so on are all examples of distributions. These many sorts of distributions can be represented by the histogram.
A histogram can be of several types:
Histogram that is uniform
Histogram with symmetry
Histogram with two modes
Probability distribution histogram
A uniform distribution demonstrates that the number of classes is too small, with the same amount of components in each class. It might involve a distribution with many peaks.
Since we can see in the given histogram,
The average frequency is 5
And almost all the bars are ending at 5
Hence,
This histogram is uniform histogram.

plot the x intercepts,maxima and minima of y=cos(x) from 0 to 2pi
Answers
Answer:
Figure of the function is included below as attachment.
Step-by-step explanation:
Let [tex]y = \cos x[/tex]As first step we have to find x intercepts, maxima and minima from 0 to 2π, which are needed to plot given function. Cosine is a trigonometric function bounded between -1 and 1 with a periodicity of 2π.
x-Intercepts
x-intercepts are those points of the function such that [tex]y = 0[/tex]. That is:
[tex]\cos x = 0[/tex]
In this case, there is a periodicity of π for [tex]y = 0[/tex]. The x-intercepts are in the following set:
[tex]S = \{\forall\,x\in\mathbb{R}|x=0.5\pi\pm\pi\cdot i,i\in\mathbb{N}_{O} \}[/tex]
Maxima
Maxima are those points of the function such that [tex]y = 1[/tex]. That is:
[tex]\cos x = 1[/tex]
In this case, there is a periodicity of 2π for [tex]y = 1[/tex]. Maxima are in the following set:
[tex]S = \{\forall\,x\in\mathbb{R}|x=0\pm2\pi\cdot i,i\in\mathbb{N}_{O} \}[/tex]
Minima
Minima are those points of the function such that [tex]y = -1[/tex]. That is:
[tex]\cos x = -1[/tex]
In this case, there is a periodicity of 2π for [tex]y = -1[/tex]. Minima are in the following set:
[tex]S = \{\forall\,x\in\mathbb{R}|x=\pi\pm2\pi\cdot i,i\in\mathbb{N}_{O} \}[/tex]
Lastly, we proceed to plot the function as well as its x-intercepts, maxima and minima with the help of a plotting tool.

What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Grandma pays upfront for you to go on an overnight trip with the school, which costs $340.
And, You make a deal that you’ll give her $25 per month until you pay it all back.
Now,
Let the number of months to pay Granma = x
Then, we can formulate;
$25x = $340
x = 13.6
After rounding,
x = 14
So, We pay 14 months to grandma;
Hence, The cost to pay grandma in 14 months = 14 x $25
= $350
Therefore, You pay $350 to Grandma.

In the early part of this century, the drug company, Merck, produced a powerful non- steroidal anti-inflammatory drug (NSAID) known as Vioxx. Vioxx was very effective in reducing pain due to arthritis and, unlike some NSAIDs, did not cause digestive system or liver problems. However, a couple of years after Vioxx was introduced to the market, some independent studies showed a possible connection between NSAIDs and increased risk of heart attack in the elderly. Since many arthritis sufferers (and many Vioxx users) are elderly, these studies were a cause of concern.
To test whether this was the case for Vioxx, Merck conducted a large-scale study in which 3025 randomly selected elderly Vioxx users were put on the drug while 2875 were given a placebo. The volunteers were monitored for 18 months. During this time, 334 of the Vioxx group members and 272 members of the placebo group suffered heart attacks.
Required:
a. Compute by hand a 90% confidence interval for the difference in heart attack risk between Vioxx users and non-Vioxx users (the placebo group.)
b. Interpret the interval. What action does it suggest should be taken regarding Vioxx?
Answers
Answer:
a
[tex]0.0028 < p_1 - p_2 < 0.0288[/tex]
b
The interval means that there is 90% confidence that the true difference between the proportion of Vioxx users who suffered from heart attack and the non-Vioxx users (the placebo group ) who suffered from heart attack lie within the interval
The use of Vioxx drug should be stopped
Step-by-step explanation:
From the question we are told that
The sample size for Vioxx users is [tex]n_1 = 3025[/tex]
The second sample size for placebo is [tex]n_2 = 2875[/tex]
The number of Vioxx users that suffered heart attack is [tex]k = 334[/tex]
The number of non-Vioxx users that suffered heart attack is [tex]g = 272[/tex]
Generally the sample proportion for Vioxx users is mathematically represented as
[tex]\r p_1 = \frac{k}{n_1}[/tex]
=> [tex]\r p_1 = \frac{334}{3025}[/tex]
=> [tex]\r p_1 = 0.11041 [/tex]
Generally the sample proportion for placebo users is mathematically represented as
[tex]\r p_2 = \frac{g}{n_2}[/tex]
=> [tex]\r p_2 = \frac{272}{2875}[/tex]
=> [tex]\r p_2 = 0.09461 [/tex]
Generally the confidence level is 90% , then the level of significance is [tex]\alpha = (100-90)\%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally the critical value of [tex]\frac{\alpha }{2}[/tex] from the normal distribution table is
[tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]
Generally the standard error is mathematically represented as
[tex]SE = \sqrt{\frac{\r p_1 (1- \r p_1)}{n_1} + \frac{\r p_2 (1- \r p_2)}{n_2} }[/tex]
=> [tex]SE = \sqrt{\frac{0.11041 (1- 0.11041)}{3025} + \frac{0.09461 (1-0.09461)}{2875} }[/tex]
=> [tex]SE = 0.0079[/tex]
Generally the margin of error is mathematically represented as
[tex] E= Z_{\frac{\alpha }{2} } * SE[/tex]
=> [tex] E= 1.645 * 0.0079[/tex]
=> [tex] E= 0.013[/tex]
Generally the 90% confidence interval is mathematically represented as
[tex]0.11041 - 0.09461- 0.013 < p_1 - p_2 < 0.11041 - 0.09461+ 0.013 [/tex]
=> [tex]0.0028 < p_1 - p_2 < 0.0288[/tex]
The interval means that there is 90% confidence that the true difference between the proportion of Vioxx users who suffered from heart attack and the non-Vioxx users (the placebo group ) lie within the interval
Looking at the interval we see that proportion of Vioxx users who suffered is more compared to non-Vioxx users (the placebo group )[i.e the both limit of the interval is positive ] hence the use of Vioxx drug should be stopped

The distribution of IQ scores for students at a large university are known to be approximately normally distributed with σ = 15. One student claims that the mean IQ for all students at the university is 100. A. Assuming that the student’s claim is true (that µ = 100), what is the probability of obtaining a simple random sample of 20 students whose mean IQ score is greater than 108. B. Suppose that you actually did collect a simple random sample of 20 students and found their mean IQ score was greater than 108. Would this give you good evidence to suggest that the mean IQ for all students at the school is greater than 100? Explain.
Answers
Answer:
A
The probability of obtaining a simple random sample of 20 students whose mean IQ score is greater than 108 is
[tex]P(\= X > 108) = 0.0084242[/tex]
B
Comparing the p-value obtained with a low level of significance (say ∝= 0.01 ) we see that the p-value is less than ∝ which implies that the null hypothesis is rejected hence we can state that there is sufficient evidence to conclude that the mean IQ for all students at the school is greater than 100
Step-by-step explanation:
From the question we are told that
The standard deviation is [tex]\sigma = 15[/tex]
The population mean is [tex]\mu = 100[/tex]
The sample size n = 20
Generally the standard deviation of the sample mean (standard error ) is mathematically represented as
[tex]\sigma_{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma_{\= x} = \frac{15 }{\sqrt{20} }[/tex]
=> [tex]\sigma_{\= x} = 3.35[/tex]
Generally the probability of obtaining a simple random sample of 20 students whose mean IQ score is greater than 108 is mathematically represented as
[tex]P(\= X > 108) = P(\frac{\=X - \mu}{\sigma_{\= x} } > \frac{108 - 100}{3.35} )[/tex]
=> [tex]P(\= X > 108) = P(Z > \frac{108 - 100}{3.35} )[/tex]
=> [tex]P(\= X > 108) = P(Z > \frac{108 - 100}{3.35} )[/tex]
=> [tex]P(\= X > 108) = P(Z >2.39 )[/tex]
From the z-table
[tex]P(z > 2.39) = 0.0084242[/tex]
So
[tex]P(\= X > 108) = 0.0084242[/tex]
The null hypothesis is [tex]H_o : \mu = 100[/tex]
The alternative hypothesis is [tex]H_a : \mu > 100[/tex]
The sample mean is [tex]\= x = 108[/tex]
Generally the test statistics is = 2.39
Generally the p-value is equal to 0.0084242
Now comparing the p-value with a low level of significance (say ∝= 0.01 ) we see that the p-value is less than ∝ which implies that the null hypothesis is rejected and we can conclude that there is sufficient evidence to conclude that the mean IQ for all students at the school is greater than 100

Determine the value of x.
OA) 59°
B) 63°
OC) 90°
OD 117°
Answers
Answer:
The value of x is 63° ⇒ B
Step-by-step explanation:
The rule for finding the sum of the interior angles of a polygon with n sides is S = (n - 2) × 180°
In the given figure
There is a polygon with 5 sides
∵ n = 5
∴ S = (5 - 2) × 180°
∴ S = 3 × 180°
∴ S = 540°
→ We have the measure of 4 angles of them
∵ The sum of the 4 given angles = 119° + 100° + 88° + 116°
∴ The sum of the 4 given angles = 423°
→ To find the 5th angle subtract 423° from 540°
∵ The measure of the fifth angle = 540° - 423°
∴ The measure of the fifth angle = 117°
→ x and 117° are linear pair angles, then their sum is 180°
∵ x + 117° = 180° ⇒ linear pair angles
→ Subtract 117 from both sides to find x
∴ x + 117 - 117 = 180 - 117
∴ x = 63°

Answers
Answer:
See Below
Step-by-step explanation:
We are given 3 equations.
3x + 8
5x - 20
and
5x + 4y
First lets solve for x using the first two
3x + 8 = 5x -20
Move the variables to one side
3x + 8 = 5x -20
-3x -3x
8 = 2x -20
+20 +20
28 =2x
28/2 =2x /2
14 = x
Now we have x = 14
Lets plug this into the second equation to solve for the angle
3(14) + 8
42 + 8 = 50
5(14) - 20
70 - 20 =50
Now, lets plug the x and the angle into the third equation to find y
5 (14) +4y = 50
70 + 4y = 50
-70 -70
4y = -20
4y/4 = -20/4
y = -5
So now we have:
x = 14
y = -5
and the angle = 50
Hope this helps!
