Could you help me solve y = x^2+6x+7?

The table below gives the list price and the number of bids received for five randomly selected items sold through online auctions. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting the number of bids an item will receive based on the list price. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.

2(3x+4)

2(4x+6)

2(3x+8)

**➷ **Expand them all to see if you get the expression:

2(3x - 4) ==> 6x - 8

2(3x + 4) ==> 6x + 8

2(4x + 6) ==> 8x + 12

2(3x + 8) ==> 6x + 16

As you can see, the correct option is B. 2(3x + 4)

**Answer:**

So the second one

**Step-by-step explanation:**

2(3x-4) =6x-8

**2(3x+4)=6x+8 2x3=6 2x4=8**

2(4x+6)=8x+12

2(3x+8)=6x+16

Answer:

2349060

Step-by-step explanation:

Given that :

Population size (n)= 51

Number of simple random samples (r) = 5

Using the combination formula :

nCr = n! ÷ (n-r)! r!

51C5 = 51! ÷ (51 - 5)!5!

51C5 = 51! ÷ 46!5!

51C5 = (51*50*49*48*47)*46! / 46! * (5*4*3*2*1)

51C5 = (51*50*49*48*47) / (5*4*3*2*1)

51C5 = 281887200 / 120

= 2349060

**Answer:**

**n=6**

"=T.INV(1-0.025,5)", and we got the critical values given by:

**n=12**

"=T.INV(1-0.025,11)", and we got the critical values given by:

**Step-by-step explanation:**

**Previous concepts**

The** t distribution** (Student’s t-distribution) is a "probability distribution that is used to estimate population parameters when the sample size is small (n<30) or when the population variance is unknown".

The **shape of the t distribution** is determined by its degrees of freedom and when the degrees of freedom increase the t distirbution becomes a normal distribution approximately.

The** degrees of freedom** represent "the number of independent observations in a set of data. For example if we estimate a mean score from a single sample, the number of independent observations would be equal to the sample size minus one."

**Solution to the problem**

**For n=6**

In order to find the critical value we need to take in count that we are conducting a two tailed test, so we are looking on the t distribution with df=n-1=6-1=5 degrees of freedom, a value that accumulates of the area on each tail. We can use excel or a table to find it, for example the code in Excel is:

"=T.INV(1-0.025,5)", and we got the critical values given by:

**For n=12**

In order to find the critical value we need to take in count that we are conducting a two tailed test, so we are looking on the t distribution with df=n-1=12-1=11 degrees of freedom, a value that accumulates of the area on each tail. We can use excel or a table to find it, for example the code in Excel is:

"=T.INV(1-0.025,11)", and we got the critical values given by:

**Answer:**

9π cm - exact value

28.26 cm - approximate value

**Step-by-step explanation:**

C = πd =9π cm - exact value

or

C=9π≈ 28.26 cm - approximate value

Using the **normal **distribution, it is found that this value was **7.5 points **below the average.

The **z-score** of a **measure X** of a normally distributed variable with **mean ** and **standard deviation** is given by:

- The z-score
**measures**how many standard deviations the measure is above or below the mean.

- Looking at the z-score table, the
**p-value**associated with this z-score is found, which is the**percentile**of X.

In this problem, the **mean **and the **standard deviation** are given, respectively, by:

.

In one game, the number of points the athlete scored was 1.2 standard deviations below his mean, hence **Z = -1.2 and the score was of X**, so:

X - 22.5 = -1.2 x 6.2

X = 15.

15 - 22.5 = 7.5.

This value was **7.5 points **below the average.
