In a recent poll of 1,500 randomly selected eligible voters, only 525 (35 percent) said that they did not vote in the last elect

irakobra [83]

Answer:

This is a response bias

Step-by-step explanation:

Response bias is a general term for a wide range of tendencies for participants to respond inaccurately or falsely to questions. These biases are prevalent in research involving participant self-report, such as structured interviews or surveys. Response biases can have a large impact on the validity of questionnaires or surveys.

This is exactly what happens here in the excercise, the result of the poll do not match the vote count, both results do not match, therefore, we can see that a lot of people lied in the poll or simply did not answer it very well.

crystal is picking blueberries.so far,she has filled 2/3 of her basket,and the blueberries weigh 3/4pound .the equation 2/3w=3/4

vesna_86 [32]

In order to do this, we multiply both sides be the amount that would make the left side equal to 1. This number is the reciprocal of the fraction, so we multiply both sides by 3/2. This is equal to:

w = 9/8

So, the blueberries in crystal's basket will weigh 9/8 pounds when it is full.

Susan invests $Z at the end of each year for seven years at an annual effective interest rate of 5%. The interest credited at th

aleksley [76]

Answer:

2.02955

Step-by-step explanation:

Given that:

Susan invests $Z as each year ends for seven years.

So we assume that Z = 1

Susan's accrued value comprises $7 invested each year at a 6 percent annual effective rate.

The cashflow interest:

The cashflow of Susan interest payments are:

Payments Time

0 1

0.05 2

2(0.05) 3

3(0.05) 4

4(0.05) 5

5(0.05) 6

6(0.05) 7

The accumulated value of this cash flow is:

$(0.05)I_{6\%} = (0.05) \dfrac{((1+0.06)_{6\%} - 6)}{0.06} \\ \\ \implies 1.1653$

So Susan accumulated values is:

X = 7 + 1.1653

X = 8.1653

Lori's accumulated value is $14, which she has set aside to plan her cash flow for interest.

The cashflow of Lori interest payments are;

Payments 0 0.025 2(0.025) 3(0.025) ......... 13(0.025)

Time 1 2 3 4 .......... 14

The accumulated value of cash flow is:

$(0.025 )(I)_{3\%} =(0.025) \dfrac{(1+0.03)_{3\%}-13}{0.03}\\ \\= 2.5719$

Now, Lori's accumulated value is:

Y = 14 + 2.5719

Y = 16.5719

Since; Susan value X = 8.1653

Lori's value Y = 16.5719

∴

$\dfrac{Y}{X}= \dfrac{16.5719}{8.1653}$

= 2.02955
