Answer:

13/50

Step-by-step explanation:

We already have our first value 13 and the second value 26. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple formula below:

13 = 26% x Y

13 = 26/100 x Y

Y = 13 x 100/26

Y = 13 x 100 / 26

y = 50

Girl 45 mins to Deliver papers on her route however if her brother have a good solid 20 minutes how long would it take if it was

LenKa [72]

Answer:

36 minutes

Step-by-step explanation:

It takes 45 mins to deliver paper on her route.

Let X be the amount of time it takes the brother to complete the route.

The brother works at the rate of 1/x route per min

The girl works at the at the rate of 1/45 route per min

Girl and brother working together works at rate of 1/20 route per min

1/x + 1/45 = 1/20

Multiply through by 180x

180 + 4x = 9x

4x - 9x = -180

-5x = -180

x = -180 / -5

x = 36 mins.

It takes the brother 36 minutes to complete route alone.

How quickly do synthetic fabrics such as polyester decay in landfills? A researcher buried polyester strips in thes oil for diff

ad-work [718]

Answer:

no enough evidence to draw up a conclusion

Step-by-step explanation:

Data:

let: $\mu _{1}$ = decay after 2 weeks

$\mu _{2}$ = decay after 16 weeks

Making the hypotheses:

Null hypothesis; $H_{o} = \mu _{1} - \mu _{2} = 0$

the deviation = 0.05

the standard difference = 4

Conditions:

The normal distribution curve can be plotted on a graph and the plot shows that the distribution is a skewed distribution.

Then,

$t = \frac{(123.8-16.4)-0}{\sqrt{\frac{4.6^{2} }{5}+\frac{16.09^{2} }{5} } } \\ = 0.989$

Therefore, it can be concluded that 0.1983 > 0.05. This presents our failure to reject the null hypothesis.

Thus, there is not enough evidence to conclude that polyester decays more in less than 2 weeks.
