Answer:
C: 5/4
Step-by-step explanation:
What is an improper fraction? An improper fraction is when the numerator (top number) is greater than the denominator (bottom number).
How is it 5/4? In the diagram, there are 4 separations, or 4 equal parts in each box. This means the denominator will be 4.
There are 5 "fourths" or five sections in these four-part boxes. So, the answer is 5/4.

A biologist studying trees constructed the confidence interval (0.14, 0.20) to estimate the proportion of trees in a large forest that are dead but still standing. Using the same confidence level, the interval was later revised because the sample proportion had been miscalculated. The correct sample proportion was 0.27. Which of the following statements about the revised interval based on the correct sample proportion is true?
A) The revised interval is narrower than the original interval because the correct sample proportion is farther from 0.5 than the calculated proportion is
B) The revised interval is narrower than the original interval because the correct sample proportion is closer to 0.5 than the mis-calculated proportion is
C) The revised interval is wider than the original interval because the correct sample proportion is farther from 0.5 than the mis-calculated proportion is
D) The revised interval is wider than the original interval because the corect sample proportion is closer to 0.5 than the mis-calculated proportion is.
E) The revised interval has the same width as the original interval.
Answer:
D) The revised interval is wider than the original interval because the corect sample proportion is closer to 0.5 than the mis-calculated proportion is.
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:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
The larger the closer to 0.5 the value of [tex]\pi[/tex], the larger the margin of error and the wider the interval is.
A biologist studying trees constructed the confidence interval (0.14, 0.20)
This means that the estimate used was of:
[tex]\pi = \frac{0.14 + 0.2}{2} = \frac{0.34}{2} = 0.17[/tex]
The correct sample proportion was 0.27.
With [tex]\pi = 0.27[/tex], the margin of error is larger as 0.27 is closer to 0.5 than 0.17. Thus, the revised interval will be wider, and the correct answer is given by option D.

b. The perimeter of a square room is 48m, how much square metre carpet is
required to cover it?
Answer:
144
Step-by-step explanation:
A square room has all sides the same length
the perimeter is the length of the sides (which are the same length) therefore dividing it by 4 to get the length of 1 side multiplied by itself will give us the area to be covered.

10. What value of x and y will make the polygon a
parallelogram?
Answer:
Step-by-step explanation:
20 = 5y
4=y
x+3y = 2(x+y-1)
x+3y = 2x +2y -2
x+3(4) = 2x + 2(4) -2
x +12 = 2x +8 -2
12-8+2 = 2x -x
6 =x
The values of x and y that makes the polygon a parallelogram is 6 and 4 respectively.
What is a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal, and opposite angles equal.
Given is a polygon,
We know opposite sides of a parallelogram are equal,
Therefore,
5y = 20
y = 20/5
y = 4
And,
Putting y = 4, in x+3y = 2(x+y-1)
x+12 = 2(x+3)
x+12 = 2x+6
x = 12-6
x = 6
Hence, The values of x and y that makes the polygon a parallelogram is 6 and 4 respectively.

Name the coordinates of P(-8, 3) under a reflection across the y-axis.
Answer:
(8,3)
Step-by-step explanation:
Hello There!
This is the rule for reflection over y axis:
(x,y) -----> (-x,y)
So if the point (-8,3) we're to reflect over the y axis then the x value would stay the same but the sign would flip
So instead of -8 it would be +8
The y value does not change so the new coordinates would be
(8,3)

a. As the sample sizeâ increases, the variance of decreases.â So, the distribution of becomes less concentrated around.
b. As the sample sizeâ increases, the variance of decreases.â So, the distribution of becomes highly concentrated around.
c. As the sample sizeâ increases, the variance of increases.â So, the distribution of becomes highly concentrated around.
d. As the sample sizeâ increases, the variance of increases.â So, the distribution of becomes less concentrated around.
Answer:
b. As the sample size â increases, the variance of decreases. â So, the distribution of becomes highly concentrated around.
Step-by-step explanation:
Let : Yi,.... Yn are = i.i.d are random variables. The probability density of the distribution varies along with the sample size. When the sample size changes, the probability density of [tex]$E^3$[/tex] also changes.
The probability distribution may be defined as the statistical expression which defines the likelihood of any outcome for the discrete random variable and it can be opposed to the continuous random variable.
In the context, when the size of the sample of the distribution size increases, it causes a decrease in the variance and so the distribution becomes highly concentrated around.

If m∠P = (19x - 5)° and x = 4, find m∠P and classify the angle (acute, right, obtuse, straight).
Answer:
71 degrees, Acute angle
Step-by-step explanation:
From the question, the equation for the Angle is given to be 19x-5, given in degrees and they want to find the value of the angle when the variable X is equal to 4.
All we need to do is change X with 4 in this equation to get
(19x4)-5) Now we just need to do some basic arithmetic to find out the value.
(76-5)=71, So 71 degrees. Now let's classify all the types of angles
1-89 degrees is a acute angle
90 degrees Is a right angle
91-179 is a obtuse angle
180 is a Straight angle
181-359 is a reflex angle
360 is a full turn.
Notice how our 71 degree angle falls into the category of a acute angle (1-89)
So our final Answer is that the angle is 71 degrees and a acute angle.
Answer:
∠ P = 71° and is acute
Step-by-step explanation:
Acute angle is between 0° and 90°
Right angle = 90°
Obtuse angle is between 90° and 180°
Straight angle = 180°
Given
∠ P = 19x - 5 ← substitute x = 4
= 19(4) - 5 = 76 - 5 = 71° ← acute angle

Harry’s tv plan cost 49.99 per month plus 3.49 per first run movie how many first run movies can he watch if he wants to keep his monthly bill to be a maximum of 100
Answer:
He can watch 14 first run movies to keep his monthly bill to be a maximum of $ 100.
Step-by-step explanation:
Given that Harry’s TV plan cost $ 49.99 per month plus $ 3.49 per first run movie, to determine how many first run movies can he watch if he wants to keep his monthly bill to be a maximum of $ 100, the following calculation must be performed:
100 - 49.99 = 50.01
50.01 / 3.49 = X
14.32 = X
49.99 + (3.49 x 14) = 98.85
Thus, he can watch 14 first run movies to keep his monthly bill to be a maximum of $ 100.

What is a correlation coefficient?The correlation coefficient, denoted as r, is a statistical measure that describes the strength and direction of the linear relationship between two variables.
It ranges between -1 and +1, where -1 indicates a perfect negative correlation (inverse relationship), +1 indicates a perfect positive correlation (direct relationship), and 0 indicates no correlation between the variables.
We have,
First, we need to find the correlation coefficient (r) of the given data.
We can use the following formula to do this:
r = [n∑(xy) - (∑x)(∑y)] / [√{n∑x² - (∑x)²} √{n∑y² - (∑y)²}]
where n is the number of data points, x, and y are the respective variables, and ∑ denotes the sum of the values.
Using the given data, we can calculate the values as follows:
n = 5
∑x = 39
∑y = 53
∑(xy) = 442
∑x^2 = 483
∑y^2 = 1249
Substituting these values into the formula, we get:
r = [5(442) - (39)(53)] / [√{5(483) - (39)^2} √{5(1249) - (53)²}]
r = [2210 - 2067] / [√(2415) √(5660)]
r = 143 / (61.898 75.245)
r = 0.374 (rounded to three decimal places)
Therefore,
The r-value of the given data is 0.374.
