Multiply <u>√2</u> by <u>√72</u>. The product is a <u>rational</u> number because <u>√144</u> can be simplified to an integer.
Step-by-step explanation:
As Landon has to prove that two product of two rational numbers, he has to choose two rational numbers from the list and then multiply and show that the product is also a rational number.
Let us define the rational numbers first
A number that can be written in the form of p/q where p,q are integers and q is not equal to zero, is called a rational number.
From the give =n list of rational numbers
Taking
√2 and √72
As we can see that the product of √2 and √72 is 12 which is also a rational number.
So,
Multiply <u>√2</u> by <u>√72</u>. The product is a <u>rational</u> number because <u>√144</u> can be simplified to an integer.

Answer:
Step-by-step explanation:
Given that a nutrition lab tested 40 hot dogs to see if their mean sodium content was less than the 325-mg upper limit set by regulations for "reduced sodium" franks
90% confidence interval is
(317.2, 326.8)mg.
Using confidence intervals,we can check whether null hypothesis is true.
Here
(left tailed test at 10% significance level)
We check whether confidence interval 90% contains the mean value.
We find 325 belongs to the confidence interval
Hence H0 is true
The hot dogs do not satisfy.
Answer:
7. about 41.8 degrees or 0.72972 radians (used , because the given leg is opposite from the angle)
8. about 50.4 degrees or 0.87946 radians (used )
9. about 12.8 degrees or 0.224 radians (used )
10. about 51.3 degrees or 0.8957 radians (used , given leg is opposite from angle)
Step-by-step explanation:
S.O.H.--C.A.H.--T.O.A
sine = opposite (to angle)/hypotenuse
cosine = adjacent (to angle)/hypotenuse
tangent = opposite (to angle)/adjacent (to angle)
I didn't know if it was degrees or radians, so I did both! I saw you on the film question asking for help, so I just wanted to do so! Have a great day!
