4 pears will be shared among 6 people. Means you need to divide 4 by 6 and that is :
4/6
So firstly, the hypotenuse is c for both ∠A and ∠B. That doesn't change whether you consider ∠A or ∠B.
Next, the opposite side is the side that doesn't touch the angle. In this case, ∠A's opposite side is a and ∠B's opposite side is b because the sides do not touch those angles.
Lastly, we have the adjacent side. This is the side that is, as the title says, adjacent to the angle. In this case, ∠A's adjacent side is b and ∠B's adjacent side is a because those sides are next to the angle.
Answer:
A sample size of 128 is needed.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population(square root of the variance) and n is the size of the sample.
How large should a sample be if the margin of error is 1 minute for a 93% confidence interval
We need a sample size of n, which is found when . We have that . So
Rounding up
A sample size of 128 is needed.
Answer:
Step-by-step explanation:
Question 3
5 (k + 4) - 2k
Use distributive property of multiplication.
5k + 20 -2k
Combine like terms to get your answer.
3k +20
Question 4
2 (3 + d - 1)
Simplify the expression in the parenthesis.
2 (2 + d)
Use distributive property of multiplication.
4 + 2d
If you wanted it to be accepted at higher levels, switch the terms around.
2d + 4
Answer: 1:2
Step-by-step explanation: Multiplying or dividing each term by the same nonzero number will give an equal ratio, For instance, the ratio of 2:4 is to the ratio of 1:2
