Answer:
No it's not, because a square has all the sides equal, but this hasn't, therefore it's not a square
Answer:
a) point estimate is 30%
b) null and alternative hypothesis would be
: p=27%
: p>27%
c) We reject the null hypothesis, percentage working people aged 65-69 had increased
Step-by-step explanation:
<em>a. </em>
Point estimate would be the proportion of the working people aged 65–69 to the sample size and equals
ie 30%
<em>b.</em>
Let p be the proportion of people aged 65–69 who is working. OECD claims that percentage working had increased. Then null and alternative hypothesis would be
: p=27%
: p>27%
<em>c.</em>
z-score of the sample proportion assuming null hypothesis is:
where
- p(s) is the sample proportion of working people aged 65–69 (0.3)
- p is the proportion assumed under null hypothesis. (0.27)
- N is the sample size (600)
then z=
= 1.655
Since one tailed p value of 1.655 = 0.048 < 0.05, sample proportion is significantly different than the proportion assumed in null hypothesis. Therefore we reject the null hypothesis.
There are 450 stickers on the sheet
And 18000 on 40 sheets
Answer:
18 units
Step-by-step explanation:
Hello, I can help you with this.
Step 1
identify
we have a equation, let's look it
A=6s2
The surface area A of a cube=6(area of a face)
area of face= side*side
so
Area=6*side*side
Step 2
isolate side from the equation

we are looking for a distance, so , we will use only the positive root
Step 3
replace the value of 1944 square units into the equation

so, the value x of a side of a cube with a total
the side of a cube is 18 units when the surface area of the cube shown is 1944 units2
Have a good day.
