Answer:
b = sqrt(57)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
8^2 + b^2 = 11^2
64+ b^2 = 121
Subtract 64
b^2 = 121-64
b^2 =57
Take the square root of each side
b = sqrt(57)
Answer:
Store A
Step-by-step explanation:
If you divide the amount of pencils needed by the amount in the packs, you can see how many packs you need. (But you have to round up because you can't buy half a pack)
So for Store A, it's 3 packs. That would total to $60
Store B also needs 3 packs, and that would be $81
5/8+ 1/4+ 1/2
= 5/8+ 2/8+ 4/8
= 11/8
= 1 3/8
The final answer is 1 3/8~
Answer:
Type 2 error
Step-by-step explanation:
H0 : μ = 261
H0 : μ > 261
By failing to reject H0 ; when the it is false. This means accepting null hypothesis when it is actually FALSE. Then a type 2 error has been committed.
This is different from a type 1 error whereby the null hypothesis is rejected when it is actually TRUE.
Hence, by finding no evidence to reject the null hypothesis during statistical testing when the actual windspeed of an F5 tornado during statistical testing is actually greater than 261 mph.
Sure, what's the question?
