Answer:

Step-by-step explanation:
Given



<em>Translation: 3 units left and 1 unit right</em>
Required
Determine the new coordinates of B
Write out the coordinates of B


When a function is shifted to the left, we have to subtract the unit from the x value of the function;
<em>Shifting by 3 units left, the new x becomes </em>
<em />
<em />
<em />
<em />
<em />
When a function is shifted upward, we have to add the unit to the y value of the function;
<em>Shifting by 1 unit up, the new y becomes </em>


Hence, the new coordinates of B is

No, there is significant difference in the use of e readers by different age groups.
Given sample 1 ( 29 years old)
=628,
=7%, sample 2( 30 years old)
=2309,
=0.11.
We have to first form hypothesis one null hypothesis and other alternate hypothesis.
π1-π2=0
π1-π2≠0
α=0.05
Difference between proportions 

The pooled proportion needed to calculate standard error is:

=(44+254)/(628+2309)
=0.10146
The estimated standard error of difference between means is computed using the formula:

=
=
=
=0.01315
Z= Pd-(π1-π2)/
=-0.04-0/0.013
=-3.0769
This test is a two tailed test so the p value for this test is calculated as (using z table)
p value:2 P(Z<-3.0769)
=2*0.002092
=0.004189
P value< significance level of 5%.
Hence there is enough evidence to show the claim that there is a significant difference in the use of e readers by different age groups.

Question is incomplete as it also includes:
Significance level of 5%.
Y= X divided by 1000
Y= X/1000
Hope it works! Good luck!
Answer: 59.92
Step-by-step explanation:
90 + 50 = 140
140 - 40% = 56
56 + 7% = 59.92
Sum of interior angles=(n-2)180
3060=(n-2)180
3060/180=n-2
17=n-2
n=17+2
n=19..
