I got 18 and 30 for my answer
Answer: 95% confidence interval = 20,000 ± 2.12

( 19228.736 , 20771.263 ) OR ( 19229 , 20771 )
Step-by-step explanation:
Given :
Sample size(n) = 17
Sample mean = 20000
Sample standard deviation = 1,500
5% confidence
∴
= 0.025
Degree of freedom (
) = n-1 = 16
∵ Critical value at ( 0.025 , 16 ) = 2.12
∴ 95% confidence interval = mean ± 


Critical value at 95% confidence interval = 20,000 ± 2.12

( 19228.736 , 20771.263 ) OR ( 19229 , 20771 )
Answer:
Just about 2100 people
Step-by-step explanation:
2 out of 5 is 60% and 7*5 is 35 so if you multiply 7 by 3 then you get 21 and if you multiply that by 100 then you get 2100
Answer:
∠ Y = ∠ V
∠ Z = ∠ W

Step-by-step explanation:
It is given that Δ XYZ is similar to Δ XVW.
Since corresponding angles of similar triangles are equal,
∠ X = ∠ X
∠ Y = ∠ V
∠ Z = ∠ W
Also, since corresponding sides of similar triangles are in proportionate,

The expression obtained after solving the given expression is,
<h3>What is a BODMAS rule?</h3>
For the Bracket, Order, Division, Multiplication, Addition, and Subtraction rules, BODMAS stands for Bracket, Order, Division, Multiplication, Addition, and Subtraction.
