Biased

Step-by-step explanation:

Hi there,

Since people at a football game are asked what their favorite sport is, it is more than likely that it would be football since they attend a game they are interested in. In other words, it is usually given that people at a football game like football. Therefore, the responses would be biased.

Hope this explanation helps.

Step-by-step explanation:

find the area of triangles + area of rectangles

area of triangles: b x h x 1/2

6 x 4 x 1/2

= 12

but two triangles, so . double it and then you get 24 for the two triangles areA

area of rectangles;

l x w

22 x 6

= 132

but two up and down rectangles, so double it = 264

now back rectangle:

l x w

22 x 4

= 88

Add it all up together and you have the surface area!

Surface Area - The area of the surface of the 3D object, NOT volume

pls mark brainliest unless someone else answered it or im wrong thank you! :D

Answer:

51, 52, 53

Step-by-step explanation:

51, 52, and 53 are all greater than 50, but less than 54

The possible numbers that Adam could have written are any number between 50 and 54, such as 51, 52, or 53.

Number systems are mathematical systems that are used to express numbers in various ways.

Given that the number is "greater than 50 and less than 54", which means it must be strictly between those two values.

Here, the range of numbers that Adam could have written is (50, 54), which means any number greater than 50 and less than 54, but not including 50 and 54 themselves.

Thus, the possible numbers that Adam could have written are any number between 50 and 54, such as 51, 52, or 53.

Answer:

5.34%.

Step-by-step explanation:

Given that,

Measured length of a line = 13.8 inches

Actual length of the line = 13.1  inches

We need to find the percent error of the measurement. We can find it as follows :

[tex]\%=\dfrac{|measured-actual|}{actual}\times 100\\\\\%=\dfrac{13.8-13.1}{13.1}\times 100\\\\\%=5.34\%[/tex]

So, the required percentage is equal to 5.34%.

Answer:

The maximum height of the ball is 380.25 feet in the air.

Step-by-step explanation:

The quadratic function:

[tex]h(t)=-16t^2+132t+108[/tex]

Models the ball's height h(t), in feet, above the ground t seconds after it was thrown.

We want to determine the maximum height of the ball.

Note that this is a quadratic function. Therefore, the maximum or minimum value will always occur at its vertex point.

Since our leading coefficient is leading, we have a maximum point. So to find the maximum height, we will find the vertex. The vertex of a quadratic equation is given by:

[tex]\displaystyle \left(-\frac{b}{2a},f\left(\frac{b}{2a}\right)\right)[/tex]

In this case, a = -16, b = 132, and c = 108. Find the t-coordinate of the vertex:

[tex]\displaystyle t=-\frac{132}{2(-16)}=-\frac{132}{-32}=\frac{33}{8}=4.125[/tex]

So, the maximum height occurs after 4.125 seconds of the ball being thrown.

To find the maximum height, substitute this value back into the equation. Thus:

[tex]h(4.125)=-16(4.125)^2+132(4.125)+108=380.25\text{ feet}[/tex]

The maximum height of the ball is 380.25 feet in the air.

Answer:

This is a geometric sequence and the ratio is equal to 4.

Step-by-step explanation:

Arithmetic means you can continue the sequence through addition or subtraction.

Geometric means you can continue the sequence through multiplication or division.

To get from 3 to 12, we could either add 9 (arithmetic) or multiply by 4 (geometric).

To get from 12 to 48, we could either add 36 or multiply by 4.

Since we are looking for a pattern, the sequence would be geometric. This is because the sequence can be continued by multiplying by 4 each time. It cannot be arithmetic because we cannot add by 9 each time.

On a side note, common difference is used when describing arithmetic while ratio is used to describe geometric.

Answer:

A.$200

Step-by-step explanation:

I = PRT/ 100

P = $6000

R = 5%

T = 8 months = 8/12 = 2/3

I = (6000 × 5 × 2/3) /100

I = 20000 / 100

I = $200

Answer:

(√6x√20) / √3 = 2√10

Step-by-step explanation:

hello :

(√6x√20) / √3 =√2x√3 x√4x√5 / √3

because : √6 = √2x√3 and √20= √4x√5 = 2x√5

now simplify by √3 :(√6x√20) / √3 =√2x2x√5

(√6x√20) / √3 = 2√10 so : a =2 and b =10

Answer:

B

Step-by-step explanation:

To find the y- intercept let x = 0

From the table for f(x)

When x = 0 → f(x) = - 4

That is the y- intercept = - 4

Given

g(x) = 3 [tex](2)^{x}[/tex]

let x = 0 , then

g(0) = 3 [tex](2)^{0}[/tex] [ [tex]2^{0}[/tex] = 1 ]

       = 3 × 1

       = 3

That is the y- intercept = 3

Thus the y- intercept of g(x) is greater → B

Answer: D) 14.3%

Step-by-step explanation:

Conditional probability formula:

[tex]P(B |\text{given that A}) =\dfrac{P(A\ and\ B)}{P(A)}[/tex]

So, The probability he or she was dissatisfied, given that he or she had hip surgery = [tex]\dfrac{\text{Number of persons are dissatisfied and has hip surgery}}{\text{Total persons have hip surgery}}[/tex]

From the table, the number of persons who are dissatisfied and has hip surgery = 15

Total persons have hip surgery = 105

Required probability = [tex]\dfrac{15}{105}\approx0.143[/tex]

In percent, Required probability = 14.3%

Correct option D) 14.3%
