Answer:

D. The company's chocolate bars weigh 3.2 ounces on average.

Step-by-step explanation:

We are given that  a company claims that its chocolate bars weigh 3.2 ounces on average.

The company took many large samples, and each time the mean weight of the sample was within the 95% confidence interval.

Definition of 95% confidence level: 95% confidence level means a range of values that you can be 95% certain contains the true mean of the population.

Thus by considering definition we can conclude that The company's chocolate bars weigh 3.2 ounces on average.

Thus Option D is correct.

D. The company's chocolate bars weigh 3.2 ounces on average.

Answer:

x = 2.8

y = 2

Step-by-step explanation:

Reference angle = 45°

Opposite = 2

Hypotenuse = x

Adjacent = y

✔️To find x, apply the trigonometric function SOH:

Sin 45 = Opp/Hyp

Sin 45 = 2/x

x*Sin 45 = 2

x = 2/Sin 45

x = 2.82842712 ≈ 2.8 (nearest tenth)

✔️To find y, apply the trigonometric function TOA:

Tan 45 = Opp/Adj

Tan 45 = 2/y

y*Tan 45 = 2

y = 2/Tan 45

y = 2

The equation you need to find x is,

12x^{\circ}+30^{\circ}=90.

Then solving for x gives you x=5.

Hope this helps.
