What is a cubic polynomial function?

A cubic polynomial function is a polynomial function whose power is at 3°. It has a general formula f(x) = ax³ + bx² + cx + d.

where;

a, b, c, and d are real numbers, hence a ≠ 0.

If the data given in the table is represented on the graph, we can see that the data value proceeds in increasing order from negative to positive, as such:

In a study of the impact of smoking on birth weight, researchers analyze birth weights (in grams) for babies born to 189 women who gave birth in 1989 at a hospital in Massachusetts. In the group, 74 of the women were categorized as smokers and 115 as non-smokers. The difference in the two sample mean birth weights (non-smokers minus smokers) is 281.7 grams and the 95% confidence interval is (76.5, 486.9). Which gives the best interpretation of what we can conclude about the impact of smoking on birth weight

Answers

Answer:

Given:

Total women - 189

Smokers - 74

Non-smokers - 115

The difference in 2 samples mean birth weight = 281.7 grams

95% confident that the mean weight = between 76.5 grams to 486.9

solution:

The best interpretation would be -

95% confident that the babies of nonsmokers have a mean weight between 76.5 grams to 486.9 grams which is much more than the babies of women smokes by comparing smokers to nonsmokers from given data.

The scatterplot shows the relationship between the number of slices of pizza eaten by each member of a football team (x) and the number of laps around the block the player could run immediately afterward (y). The equation of the regression line shown on the graph is y = 10 – 0.67x:
Use the equation above to predict the number of laps a player who ate 7 slices can run.

Answers

Answer:

5.31

Step-by-step explanation:

Given the regression line equation, [tex] y = 10 - 0.67x [/tex], where,

x = number of slices of pizza eaten

y = number of laps run immediately

Number of laps run by a player who ate 7 slices of pizza can be predicted by plugging in x = 7 into the regression line equation to find y:

[tex] y = 10 - 0.67x [/tex]

[tex] y = 10 - 0.67(7) [/tex]

[tex] y = 10 - 4.69 [/tex]

Quadrilateral PQRS is transformed by translating it 6 units to the right and then rotating it 90° clockwise
about the origin. Which coordinate pairs represent vertices of P'Q'R'S' after these two transformations?

Answers

Answer:

(y, -x -6)

Step-by-step explanation:

The coordinates of PQRS is not given, however we'll assume the coordinates of PQRS to be (x,y)

The first transformation: 6 units right

[tex](x,y) -> (x + b, y)[/tex]

Where b = 6

So, the new coordinates will be

[tex](x + 6, y)[/tex]

The second transformation: 90° clockwise

[tex](x,y) -> (y,-x)[/tex]

So, the new coordinates will be

[tex](x + 6, y)-> (y, -x -6)[/tex]

Hence, the new coordinates of PQRS is (y, -x - 6)

Answers

9514 1404 393

Answer:

Jesse

Step-by-step explanation:

Jesse's distance in 60 seconds would be ...

(60 s)(15 m)/(6 s) = 150 m

Peyton's distance in 60 seconds would be ...

(60 s)(22 m)/(10 s) = 132 m

Jesse travels farther in the same amount of time, so Jesse is moving faster.

You might find it simpler just to compute the rate of each.

Jesse: (15 m)/(6 s) = 2.5 m/s

Peyton: (22 m)/(10 s) = 2.2 m/s

Jesse's speed is higher.

What is summation?

A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.

In another word, the summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.

Given the inventory 2, 4, 2,5,3,1 if we add this inventory to the total then it will come out to be

2+ 4+ 2+5+3+1 =17 hence 17 will be the correct answer.
