Does the type of program people watch influence how much they eat? A total of 94 college students were randomly assigned to one of three treatments: watching 20 minutes of a Hollywood action movie (The Island), watching the same 20-minute excerpt of the movie with no sound, and watching 20 minutes of an interview program. While watching, participants were given snacks (M&M’S®, cookies, carrots, and grapes) and allowed to eat as much as they wanted. Subjects who watched the highly stimulating excerpt from The Island ate 65% more calories than subjects who watched the interview show. Participants who watched the silent version of The Island ate 46% more calories than those who watched the interview show.36 Identify the explanatory and response variables in this study. Then determine if it is an experiment or an observational study. Explain your reasoning.

Answers

Answer 1

Answer:

The explanatory variable is the type of program the people watched. The response variable is the number of calories consumed. This was an experiment.

A company makes plastic beach balls with a radius of 2 inches. How many square inches of plastic does the company

need to make 10 beach balls? Use 3.14 for x and round to the nearest tenth.

Recall the formula SA - 48/?.

50.24 in 2

100.5 in 2

2512 in 2

5024 in 2

Answers

Answer:

502.4 in²

Step-by-step explanation:

Area of a sphere = 4 πr²

Plastic beach balls are spherical in shape.

Hence, the Area of a sphere = 4πr²

Where r = radius = 2 inches

π = 3.14

Hence, the area of one spherical ball =

4 × 3.14 × 2²

= 50.24 square Inches

For 1 spherical ball, 50.24 square inches of plastic is needed to make it.

How many square inches of plastic does the company need to make 10 beach balls?

Therefore,

1 spherical ball = 50.24 in²

10 spherical balls = x

Cross Multiply

x = 10 × 50.24 in²

x = 502.4 in²

Therefore, 502.4 square inches of plastic is needed by the company to make 10 beach balls.

B because when you reflect over the y axis, the y value stays the same but the x value changes to the opposite of what it was before (for example, the value of x was 8 but when you reflect over the y axis, it changes to -8)

Given: ΔABC, AB=12, m∠A=60°,m∠C=45°, AB =8 Find the perimeter of ΔABC

Answers

Answer:

The perimeter of ΔABC is 43 units

Step-by-step explanation:

An illustrative diagram is shown in the attachment below.

To find the perimeter of the triangle, we will first determine the length of the unknown sides.

First, we can determine /BC/ using the Sine rule

From Sine rule

[tex]\frac{SinA}{a} = \frac{SinB}{b} = \frac{SinC}{c}[/tex]

∴ [tex]\frac{SinA}{a} = \frac{SinC}{c}[/tex]

In the diagram, [tex]a = /BC/[/tex] and [tex]c = /AB/ = 12[/tex]

m∠A=60° and m∠C=45°

∴ [tex]\frac{Sin60}{/BC/} = \frac{Sin45}{12}[/tex]

[tex]/BC/ = \frac{12 \times Sin60}{Sin45}[/tex]

[tex]/BC/ = 6\sqrt{6}[/tex]

To find /AC/, will first determine m∠B

m∠A + m∠B + m∠C = 180° (Sum of angles in a triangle)

60° +m∠B + 45° = 180°

m∠B + 105° = 180°

m∠B = 180° - 105°

m∠B = 75°

Also, using the sine rule

[tex]\frac{SinB}{b} = \frac{SinC}{c}[/tex]

From the diagram, [tex]b = /AC/[/tex]

[tex]\frac{Sin75}{/AC/} = \frac{Sin45}{12}[/tex]

[tex]/AC/ = \frac{12 \times Sin75}{Sin45}[/tex]

[tex]/AC/ = 6 + 6\sqrt{3}[/tex]

Now,

The perimeter of ΔABC = /AB/ + /BC/ + /AC/

= [tex]12 + 6\sqrt{6} + 6+6\sqrt{3}[/tex]

= 43.09 units

≅ 43 units

Hence, the perimeter of ΔABC is 43 units.

Answer:

Using the figure above, if AB = RT and ∠R = 70°, then ________.

ΔABC ~ ΔRTS

m ∠ S = 50°

ΔABC ≅ ΔRTS

m ∠ S = 60°

Let the unknown number = x

x + 308 - 126 = 450

x + 182 = 450

x = 450 - 182

x = 268

Answer:The answer is 14x-25=115    (B)

Step-by-step explanation:

he bought a certain amount of shirts, each being 14 dollars. So 14(how ever many shirts)- 25(the coupon) = Sales price

Answer:

b. 14x-25=115

Step-by-step explanation:

14 dollars each and 25 discount

the "each" here means the cost per cloth is 14, and total cost of the clothes Marco buy will increase depend on the amount of clothes.

Thus, it is 14x

The 25 discount represent that NO MATTER how many clothes Marco purchase, he only gets a discount of 25.  It is a independent value.

Total clothes bought - discount = total amount of money spent.

Thus, it is 14x-25=115

A piggy bank contains dimes and nickels that are worth a total of $42.45. If there are 197 nickels, how
many dimes are there?

Answers

Answer:

326 dimes.

Step-by-step explanation:

total value  = 197 * value of one nickel

total value = 197 * 0.05

total value = 9.85

Value of dimes = 42.45 - 9.85

Value of dimes = 32.60

1 dollar contains 10 dimes

32.60 dollars contain x dimes

1/32.60 = 10/x        Cross multiply

x = 32.60 * 10

x = 326     Dimes

Answer: 326 dimes

Step-by-step explanation:

q + 0.05(197) = 42.45

q + 9.85 = 42.45

q = 42.45 - 9.85

q = $32.6

32.6 / 0.10 = 326
