Neko [114]3 years ago
4 0

Answer:

The survey is meaningless because of nonresponse bias.

Step-by-step explanation:

The sample who responded (567) is less than half of Hayden's blog readers (1200). So, in this case, the results were really invalidated, because of the great absence of response, and the survey cannot be taken seriously at least statistically speaking.

567---100

x------35

x≈199 people said No

y= 368 said yes

An executive invests $26,000, some at 7% and some at 5% annual interest. If he receives an annual return of $1580, how much is i
Dmitriy789 [7]

Answer:

He invest $14000 for 7% and $12000 for 5%.

Step-by-step explanation:

Consider the provided information.

Let executive invest x for 7% and 26000-x for 5%.

The annual return is $1580.

Therefore, the required equation is:

\frac{7}{100} x+\frac{5}{100}(26000-x)=1580

0.07x+0.05(26000-x)=1580

0.07x+1300-0.05x=1580

0.02x=280

x=14000

26000-14000=12000

Therefore, he invest $14000 for 7% and $12000 for 5%.

I don't understand how you get 80, can I get an explanation please!
Ira Lisetskai [31]

Answer:

If angle BAD=25 degrees, it means that x=45 because 45-20=25.

This means that angle DAC is 80 degrees, because 2(45)-10=80 degrees.
