Since y + x = 3, then we could say one of them equals 2 while the other is 1. y - x = 1, then we can say 3 - 1 = 2, so y would be 2 and x would be 1
Answer:
g(3)=31.5-3
Step-by-step explanation:
first you want to find g(1) or g(x). all you have to do for this is divide every number by two, since 2/2 is 1.
g(1)=10.5-1
now to find g(30 you just multiply it all by 3.
g(3)=(10.5-1)*3
g(3)=31.5-3.
Answer:
35/59
Step-by-step explanation:
200-140x=-36
-140x=-236
35x=59
x=35/59
The line below are parallel so they have same slopes
If the green line has a slope of -1/2, the slope of the red line is also - 1/2
Answer
-1/2
Answer:
(c) The t-distribution is bell shaped
(e) The t-distribution has more values at the extremes than a standard normal distribution
(f) The t-distribution is centered at 0
Step-by-step explanation:
When the sample size is small or population variance is unknown, and we have to estimate population parameter then t- probability distribution is used.
The t-distribution has properties as follows:
- The mean of t-distribution is 0. Thus, option (f) is correct.
- t-distribution is normal. Thus, option (c) is correct.
- As compare to standard normal distribution, t-distribution has more values at the extremes. Thus, option (e) is correct.
