saveliy_v [14]

Answer:

Yes

Step-by-step explanation:

Given that in the June 2007 issue, Consumer Reports also examined the relative merits of top-loading and front-loading washing machines, testing samples of several different brands of each type.

The difference in mean values test gave a p value of 0.32

Confidence level = 95%

Alpha = 1-0.95 = 0.05

Compare p with alpha, here p >alpha

Hence we accept null hypothesis that there is no difference in the means.

Confidence interval method also will yield the same result.  i.e. confidence interval for difference of means would definitely contain 0 at 95% conf level.

So answer is yes

18,000 amounts to 21,600 in 4 years at simple interest. Find the sum of
AnnyKZ [126]

Answer:

\$20,400

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

step 1

Find the rate of interest

in this problem we have

t=4\ years\\ P=\$18,000\\ A=\$21,600\\r=?

substitute in the formula above and solve for r

\$21,600=\$18,000(1+4r)

1.2=(1+4r)

4r=1.2-1

r=0.2/4=0.05

The rate of interest is 5\%

step 2

Find the sum of  money that will amount to 25,500 in 5 years, at the same rate of interest

in this part we have

t=5\ years\\ P=?\\ A=\$25,500\\r=0.05

substitute in the formula above and solve for P

\$25,500=P(1+0.05*5)

P=\$25,500/(1.25)=\$20,400

The sum of two numbers is 97. One number is 1 more than twice the other number. Find the two numbers.​
guajiro [1.7K]

Answer:

The 2 numbers are 32 and 65.

Step-by-step explanation:

x + y = 97   where x and y are the 2 numbers.

x = 2y + 1

Substituting for x in the first equation:

2y + 1 + y = 97

3y = 96

y = 32.

So x = 2y + 1 = 64 + 1 = 65.
