1. Use the Pythagorean Theorem since this is a right triangle:
a^2 + b^2 = c^2
3^2 + b^2 = 4^2
b^2 = 4^2 - 3^2
b = √ 7
b = 3
answer : 3
A pentagon, 5 sides, all internal angles add up to 720°, so wen u do the maths, X=5
Answer: H0 : u = 6 ounces
Ha : u not equal to 6 ounces
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean.
While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
Therefore, for the case above;
H0 : u = 6
Ha : u not equal to 6.
