You would take 10.85 times .4% which gives you 4.34 then you would add 4.34 to 10.85 for a total of 15.19

As a water quality assurance employee for your local Aqua America, Inc., branch, you record a drop in water levels from 28 feet

ioda

So, it went down from 28 to 7, meaning 28 - 7 = 21, 21 feet then.

now, if we take 28 to be the 100%, what is 21 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
28&100\\
21&p
\end{array}\implies \cfrac{28}{21}=\cfrac{100}{p}\implies p=\cfrac{21\cdot 100}{28}$

Question 6<br> Express this decimal as a fraction.<br> 1.21 =<br> ✓ DONE

algol [13]

Answer: 1 and 21/100

Step-by-step explanation: Using the place value chart, we can see that 1.21 means 1 unit, 2 tenths, and 1 hundredth.

Think of 2 tenths and 1 hundredth as 21 hundredths.

So we have 1 and 21/100 which can

be written as the mixed number $1\frac{21}{100}$ .

I have attached the place value chart below.

Write in mathematical expression.

bulgar [2K]

Answer:

Step-by-step explanation:

1) "number multiplied by -6" = number times -6 (x is the number)

-6 * x = -6x

2) "subtracted from the sum of (8 and two times the number)"

sum is addition

two times x(the number) plus 8

2x + 8

3) -6x is being subtracted from 2x + 8

2x + 8 - (-6x) =

2x + 8 + 6x =

8x + 8

B. 8x + 8

A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers t

NeX [460]

Answer:

0.09

Step-by-step explanation:

Given that 50% of this population prefers the color green.

Let p the probability that one person selected from the population prefer the green color of the car. So,

p=0.05

There is only two chance, any person either prefer the green color or not, assuming this holds true for every person, so the mentioned population can be assumed as Bernoulli's population.

By using Bernoulli's theorem, the probability of exactly r success of n randomly selected from the Bernoulli's population is

$P(r)=\binom{n}{r}p^{r}{(1-p)}^{n-r}\cdots(i)$
