Which matches the inequality?
Answer:
x is greater than or equal to 0
Step-by-step explanation:
Show work to determine the value of x.
ok so since the total measurement is 180° and you know that 1 of the sides is 40° and the other 2 are the same you will just need to subtract 40 from 180 and split that in half
here's the formula
[tex](180 - 40) \div 2 = \\ 140 \div 2 = \\ 70[/tex]
therefore
x=70°

You are given data on number of radio ads and sales for a local department store. You had observations for 20 months. The correlation between ads and sales is 0.40. Does this indicate a positive and significant relationship between ads and sales at the 5% level of significance
Answer:
"No" would be the appropriate response. A further explanation is provided below.
Step-by-step explanation:
According to the question,
Number of observations,
n = 20
Significance level,
d = 5%
i.e.,
= 0.05
Calculated correlation,
= 0.40
Critical correlation value will be:
= 0.444
According to the question, we can see that the calculated correlation i.e., "0.40" is far less than the critical correlation value i.e., "0.444". The null hypothesis has always been not rejected. Thus it doesn't indicate the significant relationship.So the above it the right response.

Mary and Jane both took PSY230 last semester but they were in two different sections taught by different professors. Mary's class had a mean grade of 85 points with a standard deviation of 5 points while Jane's class had a mean grade of 80 points with a standard deviation of 10 points. Both Mary and Jane earned 88 points. Who did better in class
Answer:
Due to the higher z-score, Jane did better in class.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this question:
Whoever's grade had the better z-score did better in class.
Mary's:
Mean of 85, standard deviation of 5, grade of 88. This means that [tex]\mu = 85, \sigma = 5, X = 88[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{88 - 85}{5}[/tex]
[tex]Z = 0.6[/tex]
Jane's
Mean of 80, standard deviation of 10, grade of 88. This means that [tex]\mu = 80, \sigma = 10, X = 88[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{88 - 80}{10}[/tex]
[tex]Z = 0.8[/tex]
Due to the higher z-score, Jane did better in class.

bank wishing to increase its customer base advertises that it has the fastest service and that virtually all of its customers are served in less than 9 minutes. A management scientist has studied the service times and concluded that service times are exponentially distributed with a mean of 6 minutes. Determine what the bank means when it claims 'virtually all' its customers are served in under 9 minutes. Proportion of customers served in under 9 minutes
Answer:
"0.7769" is the right approach. A further explanation is given below.
Step-by-step explanation:
According to the question,
The parameter for the exponential distribution,
μ = 6
x = 9
Now,
⇒ [tex]P(X < 9) = 1 - exp ( \frac{-x}{\mu} )[/tex]
On substituting the given values in the above equation, we get
⇒ [tex]= 1 - exp (\frac{-9}{6} )[/tex]
⇒ [tex]=1-exp(-1.5)[/tex]
⇒ [tex]=1-0.2231[/tex]
⇒ [tex]=0.7769[/tex]

To determine whether the pipe welds in a nuclear power plant meet specifications, a random sample of welds is selected, and tests are conducted on each weld in the sample. Weld strength is measured as the force required to break the weld. Suppose the specifications state that mean strength of welds should exceed 100 lb/in2; the inspection team decides to test
H0:μ=100 versus Ha:μ>100.
Explain why it might be preferable to use this Ha rather than μ<100.
A. We want to determine if there is significant evidence that the mean strength of welds differs from 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is not satisfied.
B. We want to determine if there is significant evidence that the mean strength of welds is less than 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is not satisfied.
C. We want to determine if there is significant evidence that the mean strength of welds exceeds 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is satisfied.
D. We want to determine if there is significant evidence that the mean strength of welds equals 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is satisfied.
Answer:
C. We want to determine if there is significant evidence that the mean strength of welds exceeds 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is satisfied.
Step-by-step explanation:
Given
[tex]\mu = 100[/tex]
[tex]H_0:\mu = 100\\\\H_a:\mu > 100[/tex]
Required
State why it is preferred to [tex]Ha: \mu < 100[/tex]
From the question, we understand that the initial test is the force required to break the weld.
This represents the null hypothesis
Because the required force can not be less than the strength of the weld (it must match the force keeping the weld), the null hypothesis is represented as:
[tex]H_0:\mu = 100[/tex]
Reading the question further;
The specification requires that the mean strength should exceed 100
In inequalities, exceeds means greater than, and it is represented with >
So, the null hypothesis is rightly represented as:
[tex]H_a:\mu > 100[/tex]
Hence: (c) is true

O c. the function has exactly one x-intercept
D. the function has no x-intercepts
The function has exactly one x-intercept.
Option C is the correct answer.
What is a function?
A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Based on the table of values provided, we can see that as x increases, y also increases.
This means that the function is increasing function.
Furthermore,
Since the y-values are negative for small x-values and positive for large
x-values, there must be at least one x-intercept where the function changes sign.
So,
We can conclude that the function that generated the table of values has exactly one x-intercept.
Thus,
The function has exactly one x-intercept.

Jessica's school bus stop is 60 yards from her house. For a normal school week, how many feet will Jessica walk to and from the bus stop.
Answer:
1,800 feet
Step-by-step explanation:
Assuming that the normal school week is 5 days, she will walk for 5 days to and from. Each day she will walk 120 yards to and from the stop. Multiply that number by 5 and you get your answer of 600 yards. The answer is wanted in feet, so you have to consider yards to feet conversions. 1 yard is three feet. Therefore, you multiply 600 by 3 and you get your answer in feet.
