The answer to this question is y=28
Let's attribute a to equal probability of 2 and b to equal probability of 3
A=54/360 B=62/360
"or" means you combine the probabilities which means that AvB =116/360
now simply divide 116 by 360 and you get your answer which is 0.32
A is the correct answer my dude
Answer:
The true average mileage of the Libra Using Null hypothesis is as ;
H0:μ≤26
(Ha):μ >26
Step-by-step explanation:
Given:
Libra, will average better than 26 miles per gallon in the city
To Find:
Average mileage of the Libra.
Solution:
This problem is related to the null hypothesis and alternate hypothesis.
i.e Null Hypothesis is the statement which is true and statement which contradictory is called alternate hypothesis.
<em>“reject H0” if the sample information favors the alternative hypothesis.
</em>
<em>“do not reject H0” / “decline to reject H0” if the sample information is insufficient to reject the null hypothesis</em>
So given that condition is libra will have average better than 26
So it will include 26 and above values .
i.e. True condition is called as null hypothesis (H0)
so true average will be greater than 26
So H0:μ≤26
And the Alternate hypothesis will be the contradictory to true condition
(Ha):μ >26 .
It is 50 degrees.
Since you already know two are 90 and 40 add them together and you get 130.
A triangle has 180 degrees so minus 130 from that
180-130=50
Answer:
25 gallons
Step-by-step explanation:
Given:
total no. of gallons= 50
Percentage of sulfuric acid= 50%
Number of gallons of sulfuric acid= total no. of gallons x Percentage of sulfuric acid
Putting values in above equation:
Number of gallons of sulfuric acid= 50 x 50/100
= 50 x 1/2
= 25 !
