Basile [38]3 years ago
4 0

Answer:

1,458,783,255,601

Step-by-step explanation:

(-1,099)^2

Break it apart:

(-1,099)*(-1,099)

Multiply the signs and numbers:

Two negatives make a positive so you are left with just 1,207,801.

Next, you square 1,207,801:

(1,207,801)*(1,207,801)

And you get the number 1,458,783,255,601

Gennadij [26K]

Answer:

\$16,610.27

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=20\ years\\A=\$30,000\\ r=0.03\\n=1  

substitute in the formula above

30,000=P(1+\frac{0.03}{1})^{1*20}  

30,000=P(1.03)^{20}  

P=30,000/(1.03)^{20}

P=\$16,610.27

An observation from a normally distributed population is considered "unusual" if it is more than 2 standard deviations away from
Liula [17]

Answer:

Step-by-step explanation:

Given that an observation from a normally distributed population is considered "unusual" if it is more than 2 standard deviations away from the mean. There are several contaminants that can harm a city's water supply. Nitrate concentrations above 10 ppm (parts per million) are considered a health risk for infants less than six month of age.

We can say 1.59 and 2.52 if taken average would be the mean

Mean = 2.01

The deviations on either side = 2.52-2.01 = 0.41

This can be taken as 2 std dev

So std dev  = 0.205

Hence we can take nitrate concentration is normal with mean = 2.01 and std deviation is 0.205

N(2.01, 0.205)

Alexandra is two years older than brad. cecilia is three years younger than alexandra. all three ages added together gives a tot
MatroZZZ [7]

Let us say that:

x = age of brad

x + 2 = age of Alexandra

(x + 2) – 3 = age of Cecilia = x – 1

 

We are also given that:

x + x + 2 + x – 1 = 37

<span>
solving for x:</span>

3x + 1 = 37

3x = 36

x = 12 = age of brad

x + 2 = 14 = age of Alexandra

<span>x – 1 = 11 = age of cecilia</span>
