Answer:

17 Degrees Celsius

Step-by-step explanation:

If you like to <em>visualize </em>then recommend using a number line.

Or you can calculate it:

(Difference Temp) = (End Temp) - (Start Temp)

(Difference Temp) = (12) - (-5)

(Difference Temp) = 17

Which of these is closest to the time in years that it will take an investment to triple when it is invested in an account that
kkurt [141]

Answer:

20.4 years

Step-by-step explanation:

The nper formula in excel comes handy in this scenario:

=nper(rate,pmt,-pv,fv)

Rate is the monthly rate of 5.4%/12

Assuming actual investment is $5,000 which is pv

The triple amount would be $5,000*3=$15,000 which is future value fv.

pmt is the regular cash flow the investment which is zero

=nper(5.4%/12,0,-5000,15000)= 244.68  months

Yearly it can be expressed as = 244.68/12  =20.39  years

When rounded to one decimal place it becomes 20.4 years

Answer: 1) 8/15 2) 2 4/9 3) -13/45

Step-by-step explanation:

1/5 + 1/3 = 6/30 + 10/30 = 16/30 = 8/15

2 1/9 + 1/3 = 19/9 + 3/9 = 22/9 = 2 4/9

What sample size is needed to give a margin of error within plus-or-minus 5% in estimating a population proportion with 90% conf
VARVARA [1.3K]

Answer: 271.

Step-by-step explanation:

When the prior population proportion of success is not available, then the formula to find the sample size is given by :-

n=00.25(\dfrac{z_{\alpha/2}}{E})^2

Given : Significance level : \alpha: 1-0.90=0.1

By using the standard normal distribution table ,

Critical value : z_{\alpha/2}=1.645

Margin of error : E=0.05

Then , the required minimum sample size will be :-

n=0.25(\dfrac{(1.645)}{0.05})^2=270.6025\approx271

Hence, the required minimum sample size is 271.
