The solution to a system of two linear equations is x = 3: y = 9. How could the intersection of the graphs of the two equations

be located on a coordinate grid?
A
From the origin, move 3 units to the left, and then move 9 units down.
B
From the origin, move 3 units to the left, and then move 9 units up.
C
From the origin, move 3 units to the right, and then move 9 units up.

A beekeeper pours honey into jars. Each large jar holds 18 ounces of honey. Each small jar holds 12 ounces of honey. The beekeep
ArbitrLikvidat [17]

Answer: 1100 ounces because 20 × 30 + 10 × 50 = 1100

Step-by-step explanation:

Amount of honey contained in each large jar = 18 ounces

Number of large jar filled = 32

Total amount of honey in large jars:

= 18 ounces × 32

= 576 ounces

Amount of honey contained in each small jar = 12 ounces

Number of small jars filled = 46

Total amount of honey in small jars:

= 12 ounces × 46

= 552 ounces

The total amount of hones in the jars will be the addition of the honey in the small and large jars. This will be:

= 576 ounces + 552 ounces

= 1128 ounces

The most reasonable estimate will be:

1100 ounces because 20 × 30 + 10 × 50 = 1100

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 420 gram setting. It is
anastassius [24]

Answer:

t=\frac{424-420}{\frac{26}{\sqrt{61}}}=1.202    

p_v =2*P(t_{(60)}>1.202)=0.234  

If we compare the p value and the significance level given \alpha=0.01 we see that p_v>\alpha so we can conclude that we have enough evidence to fail reject the null hypothesis, so we can conclude that the true mean is NOT different from  420. So the specification is satisfied.

Step-by-step explanation:

Data given and notation  

\bar X=424 represent the sample mean

s=26 represent the sample standard deviation

n=61 sample size  

\mu_o =420 represent the value that we want to test

\alpha=0.01 represent the significance level for the hypothesis test.  

t would represent the statistic (variable of interest)  

p_v represent the p value for the test (variable of interest)  

State the null and alternative hypotheses.  

We need to conduct a hypothesis in order to check if the true mean is different from 420 or not, the system of hypothesis would be:  

Null hypothesis:\mu = 420  

Alternative hypothesis:\mu \neq 420  

If we analyze the size for the sample is > 30 but we don't know the population deviation so is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:  

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}  (1)  

t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".  

Calculate the statistic

We can replace in formula (1) the info given like this:  

t=\frac{424-420}{\frac{26}{\sqrt{61}}}=1.202    

P-value

The first step is calculate the degrees of freedom, on this case:  

df=n-1=61-1=60  

Since is a two sided test the p value would be:  

p_v =2*P(t_{(60)}>1.202)=0.234  

Conclusion  

If we compare the p value and the significance level given \alpha=0.01 we see that p_v>\alpha so we can conclude that we have enough evidence to fail reject the null hypothesis, so we can conclude that the true mean is NOT different from  420. So the specification is satisfied.

A friend of yours, a senior, took the Graduate Record Exam in September and scored in the 99th percentile. In February, your fri
soldi70 [24.7K]

His/her lowered score was most likely due to statistical regression.

<h3>How to determine the reason?</h3>

The missing options in the question are:

A. compensation rivalry  B. Demoralization C.  Differential selection

D.  Testing E.  Statistical regression

From the question, we have:

  • September = 99th percentile
  • February = 90th percentile

A change (whether higher or lower) in the score is caused by statistical regression.

This is so because several variables could attribute to the change in the score.

The relationship between these variables is referred to as statistical regression
