2(8a + 5b) -(2a + 3b) Part A: Simplify the expression shown above, and include all necessary work to support your answer. Part B
Alex17521 [72]

Answer:

Total cost = <em>$</em> 4.55

Step-by-step explanation:

2(8a + 5b) -(2a + 3b)

<em>Part A: Simplify the expression shown above</em>

Exapanding the brackets;

16a + 10b - 2a - 3b

Collecting like terms;

16a - 2a + 10b - 3b

14a + 7b

<em>Part B: If a represents apples that cost $0.25 each and b represents bananas that cost SO. 15 each, what is the total cost based on the expression above?</em>

a = 0.25

b = 0.15

14a + 7b

Inserting the values into the equation;

14 (0.25) + 7(0.15)

Total cost = <em>$</em> 4.55

A research company desires to know the mean consumption of meat per week among people over age 40. A sample of 610 people over a
Papessa [141]

Answer: (3.0,\ 3.2)

Step-by-step explanation:

Confidence interval for population mean is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}  (1)

, where \overline{x} = Sample mean

z_{\alpha/2}= Critical z-value

\sigma = Population standard deviation.

n= Sample size.

As per given , we have

n= 610

\sigma=1.1

\overline{x}=3.1

Significance level for 85% confidence : \alpha=1-0.85=0.15

By z-table critical two tailed z-value : z_{\alpha/2}=z_{0.075}=1.44

Put all values in (1) , we get

3.1\pm 1.44\dfrac{1.1}{\sqrt{610}}

3.1\pm 1.44\dfrac{1.1}{24.698}

3.1\pm 0.064

=(3.1-0.064,\ 3.1+0.064)=(3.036,\ 3.164)\approx(3.0,\ 3.2)

Hence, the 85% confidence interval for the mean consumption of meat among people over age 40.  = (3.0,\ 3.2)
