Step-by-step explanation:
You need to use a Z-table for this.
There are different tables, in this table i searched for the probability of 97% because that equivalent to the top 3%.
for 0.97, Z = 1.88
The formula of Z is:
Solving x:
Answer:
8
Step-by-step explanation:
You are given the hypotenuse and one leg of a right triangle, and are being asked to find the other leg. The Pythagorean theorem applies.
TW² + TY² = WY²
TW² = 17² - 15² = 64
TW = √64
TW = 8
Answer:
12
Step-by-step explanation:
Put numbers in order from least to greatest.
8,8,9,9,10,11,13,14,14,14,15,16.
Find the number in the middle.
Because 12 is an even number we have to take the two middle numbers, in this case 11 and 13, add them and then divide that number by 2.
11+13= 24
24 ÷ 2 =12
So the median weight is 12.

<span>By the time firework a has been launched, firework b has already been launched for 0.25 seconds, so if we treat the two as equations, then
a = 220 (t)
b =</span> 220 (t) + 220 (.25)
<span>And we want to know when these two equal eachother, as that's they will both detonate.
220t = 200 t + 200 (.25)
20t = 50
t = 2.5</span>
