Rob needs to mix 4.5 liters of liquid fruit punch concentrate with 0.5

1 answer:

7 0

4.5 litres of fruit punch with 0.5 litres of water.
13.5 /4.5 = 3. Multiply 0.5 by 3 to get 1.5 litres of water. Therefore, 13.5 litres of fruit punch concentrate needs 1.5 litres of water. 13.5 + 1.5 = 15 litres of fruit punch in total.

Answer:

A pint of veggies is approximately $1.75

Step-by-step explanation:

(7 × 2.85) + 5v = 28.70. 19.95 + 5v = 28.70. 5v = 28.70 - 19.95. 5v = 8.75. v = 8.75/5. v = 1.75

The heights of a random sample of 100 women are recorded. The sample mean is 65.3 inches and the sample standard deviation is 3

Keith_Richards [23]

Answer: B. $65.3\pm(2)(0.3)$

Step-by-step explanation:

The confidence interval for the population mean is given by :-

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

Given : Sample size : n= 100

Sample mean : $\overline{x}=65.3\text{ inches}$

Standard deviation: $\sigma=3 \text{ inches}$

Level of confidence = 0.95

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

Then, 95% confidence interval for the population mean will be :-

$65.3\pm (1.96)\dfrac{3}{\sqrt{100}}\\\\\approx65.3\pm(2)(\dfrac{3}{10})=65.3\pm(2)(0.3)$
