This isn't math but okay. The independent variable is what you CHANGE, the dependent variable is what you MEASURE. (you can change/tweak any of my answers as you please)

1. DV = amount of noise in the room

IV = the number of speakers


2. DV = the rate of cooling of a glass of water

IV = amount of ice


3. DV = amount of sunlight absorbed

IV = color of clothing


4. DV = the force needed to lift the block

IV = weight of the block


5. DV = amount of space needed to store the object

IV = volume of an object


6. DV = time needed to cook something

IV = temperature of the grill


7. DV = sweetness of the baked cookies

IV = amount of sugar in the mix


8. DV = amount of force needed to break the rope

IV = thickness of rope


9. DV = volume of water traveling down the river

IV = amount of rain


10. DV = softness of the ground

IV =  amount of rain


11. DV = amount of space needed

IV = temperature of a substance

andrezito [222]

Answer: 176.

Step-by-step explanation:

Formula to find the sample size is given by :-

n=(\dfrac{z^*\cdot \sigma}{E})^2

, where \sigma = Population standard deviation from prior study.

E = margin of error.

z* = Critical value.

As per given , we have

\sigma=\$675000

E= $100,000

We take 95% confidence interval.

Critical value (Two tailed)=z^*=1.96

The required sample size = n=(\dfrac{(1.96)\cdot 675000}{100000})^2

n=(13.23)^2\\\\ n=175.03299\approx176 [Round to next integer]

Hence, the required sample size = 176.

You are planning a May camping trip to Denali National Park in Alaska and want to make sure your sleeping bag is warm enough. Th
Goshia [24]

The probability that this bag will be warm enough on a randomly

selected May night at the park is 0.8106 ⇒ answer C

Step-by-step explanation:

You are planning a May camping trip to Denali National Park in Alaska

and want to make sure your sleeping bag is warm enough.

The average low temperature in the park for May follows a normal

distribution

The given is:

1. The mean is 32°F

2. The standard deviation is 8°F

3. One sleeping bag you are considering advertises that it is good for

   temperatures down to 25°F (x ≥ 25)

At first let us find the z-score

∵ z = (x - μ)/σ, where x is the score, μ is the mean, σ is standard deviation

∵ μ = 32°F , σ = 8°F , x = 25°F

- Substitute these values in the rule

∴ z = \frac{25-32}{8}=-0.875

Now let us find the corresponding area of z-score in the normal

distribution table

∵ The corresponding area of z = -0.875 is 0.18943

∵ For P(x ≥ 25) the area to the right is needed

∵ P(x ≥ 25) = 1 - 0.18943 = 0.8106

∴ P(x ≥ 25) = 0.8106

The probability that this bag will be warm enough on a randomly

selected May night at the park is 0.8106
