hope this helps
Step-by-step explanation:
Given hyperbola has a horizontal transverse axis with center at the origin.
Its standard form of equation: (x^2/a^2)-(y^2/b^2)=1
(h,k)=coordinates of center
center:(0,0)
b=2
b^2=4
c=5
c^2=25
c^2=a^2+b^2
a^2=c^2-b^2=25-4=21
equation: (x^2/21)-(y^2/4)=1
Answer:
1,800, 19
Step-by-step explanation:
102,619÷57=1800 (nearest one)
102,619-1800×57=19
Answer and Step-by-step explanation: The <u>critical</u> <u>value</u> for a desired confidence level is the distance where you must go above and below the center of distribution to obtain an area of the desired level.
Each sample has a different degree of freedom and critical value.
To determine critical value:
1) Calculate degree of freedom: df = n - 1
2) Subtract the level per 100%;
3) Divide the result by 2 tails;
4) Use calculator or table to find the critical value t*;
For n = 5 Level = 90%:
df = 4
t = = 0.05
Using t-table:
t* = 2.132
n = 13 Level = 95%:
df = 12
t = = 0.025
Then:
t* = 2.160
n = 22 Level = 98%
df = 21
t = = 0.01
t* = 2.819
n = 15 Level = 99%
df = 14
t = = 0.005
t* = 2.977
The critical values and degree of freedom are:
sample size level df critical value
5 90% 4 2.132
13 95% 12 2.160
22 98% 21 2.819
15 99% 14 2.977
Answer:
You need to plug the values for d into the equation and find the values then plug them back into Range:
Example for first one:
f(3) = 321.65 x (3) - 567.37 = 397.58
I went ahead and did the other two for you to check your answers.
Domain = { 3 , 17 , 24}
Range = { 397.58, 4900.68 , 7152.23}
