The 95% C.I will be given as follows:
mean=199
standard deviation=16.5
n=12
thus:
value of z corresponding to 95% is 1.96, thus the 95% C.I will be found as follows:
μ+/-z(σ/√n)
thus plugging in the values we get:
199+/-1.96(16.5/√12)
=199+/-9.3358
Answer: 199-9.3358≤x≤199+9.3358
multiply the price by the discount then subtract the answer from the price
4 * 0.20 = 0.80
4-0.80 = 3.20
sale price is $3.20
The website first had 200 subscribers, they gained 40 which makes it 240 and then lost 10 which is 230. 230x5= 1,150. So Adriano’s website earned $1,150
Step-by-step explanation:
2y + x2 ÷ 4
Putting values
2(4) + (6)2 ÷ 4
8 + 36 ÷ 4
8 + 9
= 17
