If the ANOVA test is statistically significant, then we can determine which groups are different by means of the F statistic, which is defined by the ratio of the mean sum square to the average square error (none of the options are correct).

The ANOVA test can be defined as a strategy to assess when differences between two or even more groups and or populations in the same are statistically significant.

Moreover, the F statistic refers to the results of the ANOVA, which is used to show statistically significant differences between groups in the sample.

Therefore, with this data, we can see that the ANOVA test is used to determine when differences between groups in the sample are significant enough to explain a given working hypothesis, and it is associated with the F statistics.

The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 115 grams of a radioactive isotope

If we start with 115g of the isotope, after one half-life the quantity will diminish to [tex]\frac{115g}{2} = 57.5[/tex] which is half the original quantity.

This can be written mathematically as: [tex]115g(\frac{1}{2})^{1}[/tex]

After the second half life: [tex]\frac{57.5g}{2} = 28.75 = \frac{115g}{4} = (115g)\frac{1}{2}^{2}[/tex]

After the third half life: [tex]\frac{28.75g}{2} = 14.37g = \frac{115g}{8} = (115g)(\frac{1}{2}) ^{3}[/tex]

But now we can see a pattern developing, because for each new half-life we are dividing the quantity by 2 to a power that increases as the number of half-lives.

Then we can take the original quantity and quickly compute for 6 half-lives:

[tex](115g)(\frac{1}{2})^{6} = (115g)(\frac{1}{64}) = \frac{115g}{64} = 1.79g[/tex]

The time it takes for the isotope to do this will depend on the isotope in question. For some it will be microsecond, and for others it will be years and decades. The isotope will typically decay to become another element or isotope.

b. The store charge for each tablet to maximize its profit is $408

c. The  domain is [0, ∞) and the range is [0, ∞).

Function:

Basically, the term function means the relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given,

Last year, an office supply store sold 220 computer tablets for $420 each. This year its manager is considering reducing the price to increase sales. She estimates that for each $12 decrease in price, the store will sell 20 additional tablets.

Here we need to find the following:

a. The function to represent the situation

b. The store charge for each tablet to maximize its profit

c. The domain and range

While we looking into the given question as have identified that,

Price of each tablet = $420

Number of tablet sold = 220

Let us consider x be the number of tablet sold and y be the total amount.

So, the function that is used to calculate the sold tablet numbers is written as,

=> y = 420x

Here the store charge for each tablet to maximize its profit is $12.

So, the current price for the tablet is $408.

Here the domain is [0, ∞) and the range is [0, ∞).

Main answer:

She bought 5 coach tickets and 6 first class tickets.

Step-by-step explanation:

Given:

Total tickets = 11

Let's First class tickets =f, Coach tickets = c.

Total tickets = f + c

     f + c = 11  

⇒  f = 11 - c  →   equation 1

Cost she used to purchase coach tickets = $260

Cost she used to purchase First class tickets = $1130

Total budget for airfare = $8080

260c + 1130f = 8080  →  equation 2

Substitute equation 1 in equation 2;

260c + 1130(11-c) = 8080

260c + 12430 - 1130c = 8080

12430 - 8080 = 1130c- 260c

870c = 4350

c = 5 peoples

Now, Substitute c in equation 1;

f + c = 11

f = 11 - 5

f = 6 peoples

For a Regression Analysis that the value of R is 0.42, the value of the Coefficient of Non-Determination is 0.8236.

Coefficient of non-determination is the variation recorded in the dependent variable which is not counted by the changes in the explanatory variable. This is calculated by subtracting Coefficient of Determination from 1.

Coefficient of Non-Determination explains the amount of unexplained, or unaccounted for, variance among two variables, or among a set of variables (predictors) in an outcome variable.

The formula for the Coefficient of Non-Determination is 1 – R².

So, in this case:

1 – R²

= 1 – (0.42)²

Let p be the percentage of teen girls who smoke to stay thin.

So, the Null Hypothesis,([tex]H_{0}[/tex]):

The test statistics that would be used here

One sample z proportion statistics:

T.S = p' - p/ [tex]\sqrt{p'(1-p')/n}[/tex] ≈N( 0,1)

Here p'= sample percent of teen girls who smoke to stay thin = 63/ 273 = 0.231

n = number of sample of teen girls = 273

Now putting these values we have:

Test statistics = 0.231 - 0.30/ [tex]\sqrt{0.231( 1- 0.231)/ 273}[/tex]

                      = -2.705

So we get the value of z-test statistics as - 2.705.

As there is not provided in the question that the level of significance so we assume it to be 5%. Now at a 5% significance level, the z table gives the critical value of -1.645 for left- the tailed test.

As test statistics is less than the critical value of z that is -2.705< -1.645. So we reject our null hypothesis as will fall in reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis.

The multiplication of the given expression in the simplified is 5000/ 729 and in mixed form is [tex]6\frac{626}{729}[/tex].

To multiply fractions with mixed numbers, first convert the mixed number into an improper fraction. Then, multiply the numerators of the fractions separately, and then multiply the denominators separately and simplify the result to obtain the answer.

A whole number and a legal fraction are combined to form a mixed number. An improper fraction is created by multiplying a mixed number by its denominator, keeping the denominator, and adding the resulting number to the proper fraction's numerator.

The given expression is

3 × (5/9) ×(5/3) × (8/9) ×[tex]1\frac{6}{9}[/tex] × [tex]1\frac{2}{3}[/tex]

When we are interested in deviations greater than or less than the hypothesized value, we do a two-sided test.

A two-tailed or two-sided test determines whether a sample is greater than or less than a specific range of values by using a two-sided critical area of distribution.

This test tests the null hypothesis. This test determines whether there is a statistically significant difference between the sample and population mean.

This test also determines whether a claim is true or not.

This test differs from a one-tailed test because one-tailed tests permit the potential for a one-directional effect. But the two-tailed tests examine the potential for two-directional (positive and negative directions) effects.

They ask for slope-intercept form of the problem.  this form:  y= mx + b

recall there is also point-slope form   of   y -y1 = m(x -x1)

They give us two points.  

point P1 (15,40)  in the form (x1,y1)

point P2(41,61)  in the form (x2,y2)

Step1:  find the slope

slope = m

m = (y2-y1) / (x2-x1)

m= (61-40) / (41-15)

m = 19 / 26

Step 2: now use the point-slope form to get the slope-intercept form. Any given point will work, I'll use P1

y - y1 = m(x -x1)

y - 40 = [tex]\frac{19}{26}[/tex](X - 15 )

use  your algebra skillz to solve for "Y" ( get "Y" by itself )

y - 40  =   [tex]\frac{19}{26}[/tex]X -  [tex]\frac{19}{26}[/tex]*15

y - 40 = [tex]\frac{19}{26}[/tex]X - [tex]\frac{285}{26}[/tex]

y - 40 =  [tex]\frac{19}{26}[/tex]X - 10[tex]\frac{25}{26}[/tex]

Y =  [tex]\frac{19}{26}[/tex]X - 10[tex]\frac{25}{26}[/tex] + 40

Y =  [tex]\frac{19}{26}[/tex]X + 30[tex]\frac{25}{26}[/tex]    this is in slope-intercept form now  

The form of the equation y − 2 = 58(x + 16) is the (b) Point Slope Form

From the question, we have the equation to be

y − 2 = 58(x + 16)

The above equation is a linear equation

A  linear equation can be represented in three forms:

When the above forms are compared to y − 2 = 58(x + 16), we have the form to be y − Y = 58(x - X)
