A
23%
C
77%
B
30%
D

Answer: A

Step-by-step explanation:

The height of the softball when it travels 12 feet using the quadratic regression model is 5.53 foot.

Correlation coefficient is used to calculate how strong the relationship is between the two variables.

When there is a statistical relationship between two or more variables, then they are said to be in correlation.

The table represents the distance and height for softball travels after being hit by the batter.

The mean of the data of distance is 5 and the mean of the data of height is 28.167. The correlation coefficient is 0.9938.

The quadratic regression model for this model is given as,

[tex]y=5.29+11.78x-0.98x^2[/tex]

At the 12 feet, the value of height y is,

[tex]y=5.29+11.78(12)-0.98(12)^2\\y=5.53[/tex]

Hence, the height of the softball when it travels 12 feet using the quadratic regression model is 5.53 foot.

2. 8³ - 14 × 6² - 2

4. |-6|

5. 7² - 3.1 - 19 × 2.1

Step-by-step explanation:

To find the expressions, find the solution of the given equation, then solve for each answer choice to see if the soultions match. If they do, then the expressions are equivalent.

2² - 3³ + 29

4 - 27 + 29 = 6

6 is the value were looking for.

1. (78 ÷ 3) - [tex]2^{4}[/tex]

(78 ÷ 3) - 16

26 - 16

= 10

not equal

2. 8³ - 14 × 6² - 2

512 - 14 × 36 - 2

512 - 504 - 2

= 6

equal

3. -|-6|

= -6

not equal

4. |-6|

= 6

equal

5. 7² - 3.1 - 19 · 2.1

49 - 3.1 - 19 · 2.1

49 - 3.1 - 39.9

45.9 - 39.9

= 6

equal

Hence, choices 2, 4, and 5 have a value of 2² - 3³ + 29.

If -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)

The root of the polynomial function is given as:

-3 + i

The above root is a complex root.

If a polynomial has a complex root, then the conjugate of the root is also a root of the function

The conjugate of -3 + i is -3 - i

Hence, if -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)

The value of y is 3 units.

This characteristic is referred to as resemblance or comparable figures when two or more items or figures appear to be the same or equal based on their shapes. These figures always superimpose one another regardless of how they are magnified or diminished. When two shapes, such triangles, polygons, or quadrilaterals, have the same dimension or common ratio but a different size or length, they are referred to as comparable figures in geometry.

Given quadrilateral's are similar

ABCD ≈ EFGH

for similarity the angles of both figures are equal and ratio of length of their sides are equal,

so AB/EF = BC/FG = CD/GH = DA/HE

we have AB = 3, EF = 2

CD = 4.5 and GH = y

substitute the values

3/2 = 4.5 /y

y = (4.5 x2)/3

y = 3 units.

Hence the measure of y is 3 units.

When the weight of x is 10lbs less than y,

Then,

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

Now we have,

Step-by-step explanation:

The answers to your questions are as we have them below:

a.   s ( 2 burgers + 1soda )

b.  s ( $16.00 + $2.50) ≤ $100

c. The maximum number of sodas that can be purchased is 5.40 sodas

An algebraic expression is an expression containing integer constants, variables and algebraic operations

Detailed solution of the above is given below:

One Burger costs $8.00

One soda costs $2.50

Combined = s (2burgers + 1soda)

where s is the number of persons ordering.

a.   s ( 2 * $8.00 + $2.50 )

     s ( $16.00 + $2.50) = s($18.50) assuming that the hotdogs will be the total amount to be spent

b. if the cant spend more than a $100 gift card, the inequality will be

 s ( $16.00 + $2.50) ≤ $100

 s($18.50)   ≤ $100

 s ≤ [tex]\frac{100}{18.50}[/tex] = 5.40

Therefore the number of burgers and soda they can buy is

5.40 (2burgers + 1soda) = 10.80 burgers and 5.40sodas

c.  s ( $16.00 + $2.50) ≤ $100

 s($18.50)   ≤ $100

 s ≤ [tex]\frac{100}{18.50}[/tex] = 5.40

The maximum number of sodas that can be purchased is 5.40 sodas

In conclusion, the algebraic expression for the orders you and your friends will make combined is:  s ( 2 burgers + 1soda )
