Answer:
sqrt7
Step-by-step explanation:
cosA = b/3 = sqrt2 /3
so b = sqrt2
apply the pythagorean theorem
a = sqrt7
Wrong because you need to add the -2 to the 8.... I hope this helps
Easy
4 and 1/3+7 and 1/5=4+1/3+7+1/5=4+7+1/3+1/5=11+5/15+3/15=11+8/15=11 and 8/15
answer is D
Answer:
x= 0.5
or x= -1.5
Step-by-step explanation:
Let's solve your equation step-by-step.
4x2+4x−3=0
Step 1: Factor left side of equation.
(2x−1)(2x+3)=0
Step 2: Set factors equal to 0.
2x−1=0 or 2x+3=0
x= 1/2 or x= −3/2
Answer:
The smallest sample size to satisfy the conditions is n=500.
Step-by-step explanation:
The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:

The largest sample size required will be for the minimum p or (1-p).
This happens to be the proportion that can play other instruments: 2%.
Then, we can calculate the minimum sample size as:
