Answer:
10.8 cm
Step-by-step explanation:
we know that
1) A square picture with side length 30 cm is scaled by 60% on a photocopier
Remember that

so
The length of the first copy of the picture is

2) The copy is then scaled by 60% again
so
The length of the second copy of the picture is

Answer:
9 and 8 are linear and 10 is non linear
Step-by-step explanation:
an = dn - c
The an stands for the nth term of the pattern. So a1 is the first term and a2 is the second term of the pattern. The d is the difference between each of the terms. The n stands for the term you're calculating. If you're calculating the third term, then n is 3. And c is a constant that you'll need to calculate.
For example, the linear number pattern of 1, 3, 5, 7, 9, … has an equation of:
an = 2n - 1.
Answer: n< 3
Step-by-step explanation:
5n - 14 < 1 . add 14 to both sides
5n -14 +14 < 1 + 14
5n +0 < 15
5n < 15 divide both sides by 5 .5n/5 = 15/5
n < 3
Answer:
<em>The number of people would have participate in opinion poll</em>
<em>n = 15,267</em>
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given data an opinion poll reported that 36% believe a certain governor broke campaign financing laws in his election campaign.
<em>Given proportion = 36% =0.36</em>
<em>Given the margin of error = 1% =0.01</em>
<em>Level of significance = 99% 0 r 0.01</em>
<em>Z₀.₀₁ = 2.576</em>
<u><em>step(ii):</em></u><em>-</em>
<em>The margin of error of Population proportion is determined by</em>



√n = 123.648
Squaring on both sides , we get
<em>n = 15,267</em>
<u><em>final answer:</em></u><em>-</em>
<em>The number of people would have participate in opinion poll</em>
<em>n = 15,267</em>
Answer: x =2
Step-by-step explanation:
5x - 8 = 3x - 4
2x = 4
x = 2
checking the work:
5(2) - 8 = 3(2) - 4
10 - 8 = 6 - 4
2 = 2
