Part A:
I got the number of kids in the survey which is 130 and I found 70 which is the amount of kids who like playing on a pc/console. I took 130 and 70 and converted it into a fraction 70/130, I simplified it to 7/13 and used a calculator to get my percentage which I rounded and got 53%
Part B:
I drew a table and just focused on column two. I looked at how many people don't like phone or pc and I found that 10 is how many people like phone and not pc, 30 is people who dont like phone or pc, together its 40, so you need to find what the percentage 30 is of 40, or 3/4, I used a calculator and converted it into a percentage and I got 75%
Answer: the answer is 66
Step-by-step explanation:
Answer:
The answer is A
Step-by-step explanation:
Use the distributive property
Answer: x = 58°
Step-by-step explanation:
Sine = opposite leg ÷ hypotenuse
We need to find the hypotenuse first with the Pythagorean theorem.
a² + b² = c²
5² + 8² = c²
25 + 64 = c²
89 = c²
√c² = √89
c = 9.43398
c ≈ 9.43
Sine = opposite leg ÷ hypotenuse
Opp. leg - 8
Hypotenuse - 9.43
To find this, you have to use the calculator
Make sure the calculator is on scientific
If your calculator is on your computer and in full screen, find 8 ÷ 9.43 and then click sin⁻¹, you should get 58.03334
If your calculator is on your computer in mini screen, find 8 ÷ 9.43. This time, click the arrow that looks smth like this: ↑
When you do that, you should be able to see sin⁻¹, so you click that and you'll also get 58.03334
58.03334 ≈ 58
x = 58°
Hope I helped! Sorry I took so long
Answer:
(A)
![C_n=3+2n](https://tex.z-dn.net/?f=C_n%3D3%2B2n)
(B)
![C_1_0=23](https://tex.z-dn.net/?f=C_1_0%3D23)
Step-by-step explanation:
(A)
we are given
![C_n_+_1=C_n+2](https://tex.z-dn.net/?f=C_n_%2B_1%3DC_n%2B2)
![C_1=5](https://tex.z-dn.net/?f=C_1%3D5)
Firstly, we will find few terms
![C_2=C_1+2](https://tex.z-dn.net/?f=C_2%3DC_1%2B2)
![C_2=5+2](https://tex.z-dn.net/?f=C_2%3D5%2B2)
![C_2=7](https://tex.z-dn.net/?f=C_2%3D7)
![C_3=C_2+2](https://tex.z-dn.net/?f=C_3%3DC_2%2B2)
![C_3=7+2](https://tex.z-dn.net/?f=C_3%3D7%2B2)
![C_3=9](https://tex.z-dn.net/?f=C_3%3D9)
![C_4=C_3+2](https://tex.z-dn.net/?f=C_4%3DC_3%2B2)
![C_4=9+2](https://tex.z-dn.net/?f=C_4%3D9%2B2)
![C_4=11](https://tex.z-dn.net/?f=C_4%3D11)
so, we will get terms as
5, 7 , 9 , 11
we can see that this is arithematic sequence
First term =5
common difference =d=7-5=2
now, we can use nth term formula
![C_n=C_1+(n-1)d](https://tex.z-dn.net/?f=C_n%3DC_1%2B%28n-1%29d)
now, we can plug values
![C_n=5+2(n-1)](https://tex.z-dn.net/?f=C_n%3D5%2B2%28n-1%29)
![C_n=5+2n-2](https://tex.z-dn.net/?f=C_n%3D5%2B2n-2)
![C_n=3+2n](https://tex.z-dn.net/?f=C_n%3D3%2B2n)
(B)
we can plug n=10
![C_1_0=3+2\times 10](https://tex.z-dn.net/?f=C_1_0%3D3%2B2%5Ctimes%2010)
![C_1_0=23](https://tex.z-dn.net/?f=C_1_0%3D23)
