You have -9 -(-10). So when you have a subtraction symbol next to a negative, just like this problem. You will then have a positive 10.

So...
Negative and a Positive make a [Negative]
Positive and a Negative make a [Negative]
Positive and a Positive make a [Positive]
Negative Negative make a [Positive]

Then you add -9 and 10. You go closer to the 0. Then you have 1.

Aperson invest 10,000 shillings for 40 months compounded monthly. Find the accumulated amount If the rate is 5% per annum.

monthly interest rate is : $\sqrt[12]{1.05}$

So in forty month there will be : 10 000 * ( $\sqrt[12]{1.05}$ )^40 ≈11 776,06

I NEED HELP WITH THIS! ANYONE???

Answer:

y-axis, x-axis, y-axis, x-axis

Step-by-step explanation:

Alright, so this problem looks a lot harder than it really is. When you flip a point across the x axis, y becomes negative, and when it is flipped across the y axis, x becomes negative. This means that if the x value changes signs it was flipped on the y axis, and vice versa.

A machine is used to fill containers with a liquid product. Fill volume can be assumed to be normally distributed. A random samp

Answer:

There is no statistical evidence at 1% level to accept that the mean net contents exceeds 12 oz.

Step-by-step explanation:

Given that a random sample of ten containers is selected, and the net contents (oz) are as follows: 12.03, 12.01, 12.04, 12.02, 12.05, 11.98, 11.96, 12.02, 12.05, and 11.99.

We find mean = 11.015

Sample std deviation = 3.157

a) $H_0: \bar x= 12 oz\\H_a: \bar x >12$

(Right tailed test)

Mean difference /std error = test statistic

$\frac{11.015-12}{\frac{3.157}{\sqrt{10} } } \\=-0.99$

p value =0.174

Since p >0.01, our alpha, fail to reject H0

Conclusion:

There is no statistical evidence at 1% level to accept that the mean net contents exceeds 12 oz.
