Divide the circumference by pi, then divide that by 2, then you would have the radius, and the area is r squared multiplied by pi
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 .
Answer:
x=3
Step-by-step explanation:
The equation will be 3+6x=21 since we know that the soft drink costs 3 dollars and he bought 6 candy bars(6 times x or 6x). We also know that the total cost for this merchandise is 21 dollars. Now you solve the equation! First subtract 3 from both sides(since the inverse for addition is subtraction we SUBTRACT 3 from bothe sides). You are left with 6x=21-3 or 6x=18. Now you divide Each side by 6(because the inverse operation of multiplication is division). You have the answer! x=18/6 or x=3! Hope it helped!!
Table for the question :
Students ____ minutes per day
Leah _________45
Roberts _______17
Jules _________36
Apollo _______ 24
Calculate the Number of calories each student burn for 1 day of activity :
Answer:
Leah =. 630
Jules = 504
Roberts = 306
Apollo = 432
Step-by-step explanation:
Given that:
Skating burns 14 calories per minute
Running burns 18 calories per minute
Number of calories each student burn for 1 day of activity :
SKATING ;
Leah: = 14 * 45 = 630
Jules = 14 * 36 = 504
RUNNING ;
Roberts : 18 * 17 = 306
Apollo : 18 * 24 = 432
