Answer:
Angle BCF= 107 degrees
Step-by-step explanation:
for this question, you need to use the alternate angle which means angle EDC is equal to angle CFA. All the angles in a triangle makeup up 180 degrees. so with angle CFA AND ABC we can minus it from 180 degrees to find angle BCF. So 180-41-32=107

A chocolate company produces 2 types of chocolate type A and type B. The company selects 25 random packages of each type to check their weight and finds that one package of type Ahas an incorrect weight and 3 packages of type B have an incorrect weight. How many packages should the company predict have an incorrect weight when it checks 2000 of each type?
Answers
Answer:
80 chocolates type 'a' and 240 chocolates type 'b"
Step-by-step explanation:
if the company selects 2000 random chocolates of each type we ca predict that the amount of chocolates that have an incorrect weight will be:
Type 'a': 2000x0.04 = 80
Type 'b': 2000x0.12 = 240
The company is expected to find 80 chocolates type 'a' and 240 chocolates type 'b' that have incorrect weight.

sat scores in one state is normally distributed with a mean of 1403 and a standard deviation of 200. Suppose we randomly pick 32 SAT scores from that state. a) Find the probability that one of the scores in the sample is greater than 1484. P(X > 1484) = b) Find the probability that the average of the scores for the sample of 48 scores is greater than 1484 P(X > 1484) = Round each answer to at least 4 decimal places.
Answers
The probability that one of the scores in the sample is less than 1484 is 0.2437 .
a)Given that mean u = 1403
standard deviation σ = 200
sample size n = 32
P(x>1484) = P(X-u/σ > 1484-1403/200)
= P (z > 0.405)
P(x>1484) = 0.2437 .
hence the probability that one score is greater than 1484 is 0.405 .
b) Now we have to find the average of the scores of 48 samples.
P(x>1484)
= P(x-μ/ σ/√n> 1484-1403 /200/√48)
= P(z>2.805.)
Now we will use the normal distribution table to calculate the p value to be 0.002516.
p-value = 0.0025
Normal distributions are very crucial to statistics because not only they are commonly used in the natural and social sciences but also to describe real-valued random variables with uncertain distributions.
They are important in part because of the central limit theorem. This claim states that, in some cases, the average of many samples (observations) of a random process with infinite mean and variance is itself a random variable, whose distribution tends to become normal as the number of samples increases.

a researcher is interested in the relationship between happiness and gpa of high school students. after surveying 50 students, he determines that there is a correlation between these two variables of .90. this is considered a: group of answer choices strong negative linear correlation strong positive linear correlation weak negative linear correlation weak positive linear correlation
Answers
The correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.
A correlation coefficient measures the strength and direction of the relationship between two variables. In this case, the correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.
A positive correlation means that as one variable (in this case, happiness) increases, the other variable (GPA) also tends to increase. The magnitude of the correlation coefficient, which ranges from -1 to 1, represents the strength of the relationship. A value of 0.90 indicates a very strong positive linear correlation, suggesting that there is a consistent and significant relationship between happiness and GPA.
This means that as the level of happiness increases among high school students, their GPA tends to be higher as well. The correlation coefficient of 0.90 suggests a high degree of predictability in the relationship between these two variables.
It is important to note that correlation does not imply causation. While a strong positive correlation indicates a relationship between happiness and GPA, it does not necessarily mean that one variable causes the other. Other factors or variables may also influence the relationship between happiness and GPA.

Answer:
79.2Step-by-step explanation:
QA = QC = 5.9 ⇒ PA = 27.4 - 5.9 = 21.5
PB = PA = 21.5
CR = BR = 12.2
So, the perimeter:
P = 27.4 + 5.9 + 2×12.2 + 21.5 = 79.2
The perimeter of the triangle PQR is 79.2 units.
What is Perimeter?Perimeter of a straight sided figures or objects is the total length of it's boundary.
Given a triangle PQR.
An incircle is drawn inside the triangle.
We know that the length of the tangents which are drawn from an exterior point to the circle are equal.
Using this property and the given lengths,
PQ = 27.4
PR = (27.4 - 5.9) + 12.2 = 33.7
QR = 5.9 + 12.2 = 18.1
Perimeter of the triangle = 27.4 + 33.7 + 18.1 = 79.2 units
Hence the perimeter is 79.2 units.

Life on Other Planets Forty-six percent of people believe that there is life on other planets in the universe. A scientist does not agree with this finding. He surveyed 120 randomly selected individuals and found 48 believed that there is life on other planets. At a = 0.10, is there sufficient evidence to conclude that the percentage differs from 48? Source: American Health, Inc.
Answers
According to the given information, 46% of people believe that there is life on other planets. A scientist, who disagrees with this finding, conducted a survey of 120 randomly selected individuals and found that 48 of them believed in life on other planets. To determine if there is sufficient evidence to conclude that the percentage differs from 48 at a significance level (α) of 0.10, a hypothesis test is needed.
The null hypothesis (H0) states that the percentage is equal to 48%, while the alternative hypothesis (H1) states that the percentage differs from 48%. In this case, the sample proportion (p) is 48/120 = 0.4, and the hypothesized proportion (p0) is 0.48.
To perform the hypothesis test, we need to calculate the test statistic (z) and compare it to the critical values. The test statistic can be calculated using the formula z = (p - p0) / √(p0 * (1 - p0) / n), where n is the sample size. After calculating the test statistic, we compare it to the critical values corresponding to α = 0.10.
If the test statistic falls within the critical region, we reject the null hypothesis and conclude that there is sufficient evidence to claim that the percentage differs from 48%. If it falls outside the critical region, we fail to reject the null hypothesis and cannot conclude that the percentage differs from 48% based on this sample.

Answers
The exact value of the series ∑n=0infinitynπ^2n/(16^2n * (2n+1)!) is approximately -0.190985.
To find the exact value of the series, we need to evaluate each term and sum them up. Starting with the given expression, we have (-1)^n * π^(2n) / (16^(2n) * (2n+1)!). Breaking down each term, we have (-1)^n, π^(2n), 16^(2n), and (2n+1)!.
The term (-1)^n represents alternating signs, where it alternates between positive and negative for each value of n. The term π^(2n) represents π raised to the power of 2n. The term 16^(2n) represents 16 raised to the power of 2n. The term (2n+1)! represents the factorial of 2n+1.
By substituting the values of each term into the given expression and summing them up from n = 0 to infinity, we can approximate the value to be approximately -0.190985.
