Since (AB) ̅≅(AD) ̅ (the lines beside the parentheses are to show that they are lines) we have congruent hypotenuses. (AC) ̅≅(AC) ̅ so legs are ≅ So, es; ΔACB≌ΔACD by HL. The answer is D.Yes; ΔACB≌ΔACD.
Hope this helped!

Answer:
Set of hypothesis.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 20.5 oz
Sample mean,
= 20.4 oz
Sample size, n = 50
Population standard deviation, σ = 2.25 oz
First, we design the null and the alternate hypothesis
We use One-tailed z test(left tailed) to perform this hypothesis.
Formula:
Putting all the values, we have
Based on the significance level, we can make our decision and complete the hypothesis testing.
We may accept the null hypothesis or fail to accept depending on different significance level.
The first thing we need to distinguish is what 1 and 3/4 means. So, 3/4 = .75, so 1 and 3/4 = 1.75
So, we need 1.75 cups of flour for one batch, since you're making three batches, you need three times as much, so
1.75 * 3
5.25 is the answer, to put it back in to fractions,
5 and 1/4 cups of flour are needed.
