The measure of angle F in the parallelogram is 55 degrees.
What is the measure of angle F?When two figures are similar, it means that their corresponding angles are equal and their sides are in the same ratio.
The figures in the image are two similar parallelograms:
Since the parallelograms are similar, their sides are in the same ratio.
Check:
27/21 = 9/7 => TRUE
Now, since the corresponding angles are equal:
Angle N = Angle E
Hence ;
Angle E = 125 degrees
Note that; the consecutive angles of a parallelogram are supplementary.
Hence:
Angle E + Angle F = 180
125 + Angle F = 180
Angle F = 180 - 125
Angle F = 55°
Therefore, angle E measures 55 degrees.
Option C) 55° is the correct answer.

The distribution of the amount of money spent on book purchases for a semester by college students has a mean of $300 and a standard deviatin of $50.
Assuming no information concerning the shape of the distribution is known, what percentage of the students spent between $200 and $400?
a) at least 95%
b) approximately 95%
c) approximately 68%
d) at least 75%
The correct option for this question is c) approximately 68% of the students spent between $200 and $400.
Step 1: Identify the given information. The mean is $300, and the standard deviation is $50. The range is between $200 and $400.
Step 2: Calculate the number of standard deviations between the mean and each boundary. For $200, it's ($200 - $300) / $50 = -2 standard deviations. For $400, it's ($400 - $300) / $50 = 2 standard deviations.
Step 3: Since we don't have information about the shape of the distribution, we will use the Empirical Rule, which states that for a normal distribution, approximately 68% of the data falls within 1 standard deviation, 95% within 2 standard deviations, and 99.7% within 3 standard deviations of the mean.
Step 4: In this case, we are looking at 2 standard deviations from the mean (between $200 and $400). According to the Empirical Rule, approximately 95% of the data falls within this range. However, since we don't know the exact shape of the distribution, we can't say for certain that 95% of the students spent between $200 and $400. However, we do know that at least 68% of the students would fall within 1 standard deviation of the mean. Thus, we can conclude that approximately 68% of the students spent between $200 and $400.

Find the convergence set of thegiven power series: ∑n=1[infinity](x−2)nn2 The above series converges for≤x≤
The convergence set of the power series ∑n=1∞ \((x-2)^n/n^2\) is [1, 3). The series converges for x values in the interval [1, 3), and diverges for x values outside of this interval.
At the endpoints x = 1 and x = 3, the series converges for x = 1 and diverges for x = 3.
How to determine the convergence set of the power series?To find the convergence set of a power series, we can use the ratio test:
lim[n→∞] |\((x - 2)(n+1)^2 / n^2\)| = lim[n→∞] |\((x - 2)(1 + 2/n)^2\)| = |x - 2| lim[n→∞] \((1 + 2/n)^2\)
Since lim[n→∞] \((1 + 2/n)^2 = 1\), the series converges if |x - 2| < 1, and diverges if |x - 2| > 1.
If |x - 2| = 1, then the ratio test is inconclusive, so we need to check the endpoints x = 1 and x = 3 separately.
For x = 1, the series becomes:
∑n=1infinitynn2 = ∑n=1infinitynn2
which is the alternating harmonic series, which converges by the alternating series test.
For x = 3, the series becomes:
∑n=1infinitynn2 = ∑n=1[infinity]nn2
which diverges by the p-series test with p = 2.
Therefore, the convergence set of the series is:
1 ≤ x < 3
In interval notation, this can be written as:

In a given right triangle, If 0 º < x < 90 º and cos x = √ 3 / 2, then sin x = ?
Answer:
1/2
Step-by-step explanation:
The "Pythagorean relation" between trig functions can be used to find the sine.
Pythagorean relationThe relation between sine and cosine is the identity ...
sin(x)² +cos(x)² = 1
This can be solved for sin(x) in terms of cos(x):
sin(x) = √(1 -cos(x)²)
ApplicationFor the present case, using the given cosine value, we find ...
sin(x) = √(1 -(√3/2)²) = √(1 -3/4) = √(1/4)
sin(x) = 1/2

In a sample of 20 items, you found six defective. In constructing a confidence interval for the proportion of defectives, you should use: the plus four method. the large-sample interval. neither of these two methods.
To construct a confidence interval for the proportion of defectives, we should use the plus four method.
Since the sample size is 20, which is not very large, the large-sample interval is not appropriate. Instep, we ought to utilize a strategy that's suitable for little test sizes.
The plus four method is one such method that is commonly used when the sample size is small. Therefore, to construct a confidence interval for the proportion of defectives, we should use the plus four method.
The plus four strategies may be a strategy for building a certainty interim for an extent when the test estimate is little.
To utilize this strategy, we to begin with include four fanciful perceptions to our test, two of which are flawed and two of which are not imperfect.
This increments the test estimate to 24, which permits us to utilize the typical guess to the binomial dispersion to build the certainty interim.
The equation for the certainty interim utilizing the also four strategies is:
p ± zα/2 √((p + 2) (1 - p + 2) / n + 4)
where:
p is the test extent (number of defectives/test estimate)
zα/2 is the basic esteem from the standard typical dissemination at the level of importance α/2
n is the test estimate (counting the included four nonexistent perceptions)

Find the sum of the arithmetic series : 28 + 28.4 ... + 42.
The sum of the arithmetic series of 28 + 28.4 ...+ 42 is 1260.
What is arithmetic series?An arithmetic series is a sequence of numbers in which each term is obtained by adding a constant difference, called the common difference, to the preceding term.
According to question:To resolve this issue, we can utilise the following formula for the sum of an arithmetic series:
S = (n/2) * (a₁ + aₙ)
When n is the number of terms, a1 is the first term, and an is the nth term, S is the series total.
To find the number of terms, we need to figure out the pattern of the series. The common difference (d) is expressed as follows:
d = 28.4 - 28 = 0.4
To get from 28 to 42, we need to add (42 - 28)/0.4 = 35 terms.
So the number of terms is:
n = 35 + 1 = 36
The first term is a₁ = 28, and the last term is aₙ = 42.
Now we can plug these values into the formula:
S = (n/2) * (a₁ + aₙ)
= (36/2) * (28 + 42)
= 18 * 70
= 1260
Therefore, the sum of the arithmetic series is 1260.
