Answer:
here it is
Step-by-step explanation:
Answer:
{y | y = –7, –1, 0, 9}
Choice B is correct
Step-by-step explanation:
The range of a function y = f(x) refers to the set of y - values for all values of x for which the function is real and defined.
The set of y values from the given table is;
–7, –1, 0, 9
Therefore, the range of the given function is;
{y | y = –7, –1, 0, 9}
Answer:
We accept H₀ with the information we have, we can say level of ozone is under the major limit
Step-by-step explanation:
Normal Distribution
population mean = μ₀ = 7.5 ppm
Sample size n = 16 df = n - 1 df = 15
Sample mean = μ = 7.8 ppm
Sample standard deviation = s = 0.8
We want to find out if ozono level, is above normal level that is bigger than 7.5
1.- Hypothesis Test
null hypothesis H₀ μ₀ = 7.5
alternative hypothesis Hₐ μ₀ > 7.5
2.-Significance level α = 0.01 we will develop one tail-test (right)
then for df = 15 and α = 0,01 from t -student table we get
t(c) = 2.624
3.-Compute t(s)
t(s) = ( μ - μ₀ ) / s /√n ⇒ t(s) = ( 7.8 - 7.5 )*4/0.8
t(s) = 0.3*4/0.8
t(s) = 1.5
4.-Compare t(s) and t(c)
t(s) < t(c) 1.5 < 2.64
Then t(s) is inside the acceptance region. We accept H₀
Answer:
T= PV/NR

To find the area, you will need to times the length with the width.
So,
2.25*1.8=4.05 meters
1m=100cm
4.05m=405cm
Hope this helps.
