Answer:
The company's chocolate bars weigh 1.6 ounces on average.
Step-by-step explanation:
We are given that a company claims that its chocolate bars weigh 1.6 ounces on average.
It took many large samples, and each time the mean weight of the sample was within the 95% confidence interval.
95% confidence level means a range of values that you can be 95% certain contains the true mean of the population.
Thus by definition we can say that The company's chocolate bars weigh 1.6 ounces on average.
Hence Option B is correct.
Answer:
65 miles
Step-by-step explanation:
y=55+0.35x
77.75 = 55+0.35x
77.75 - 55 = 0.35x
22.75 = 0.35x
22.75 ÷ 0.35 = 0.35x ÷ 0.35
65 = x
x = 65

Answer: 55
Step-by-step explanation: There is one simple theorem we need to know in order to solve for this.
Triangle Angle-Sum Property: All three angles interior angles of a triangle add up to 180°.
Thus, we could label the points A, B, and C, and set up an algebraic expression.
Let A = 27, B = 98, and C = x.
A + B + C = 180°.
Substituting A, B, and C we get:
27 + 98 + x = 180°.
Adding, we get:
125 + x = 180°
Subtracting 125 by 180, we get:
x = 55°
Thus, the angle X is 55°.
We could have simply solved this by just doing 180 - 98 - 27 = 55 in the first place, but I wanted to show you how I got such results.
