Answer: b) ΔADC ≡ ΔBCD by SAS

<u>Step-by-step explanation:</u>

Step 1: AD = BC SIDES are congruent

Step 2: ∠ADC ≡ ∠BCD ANGLES are congruent

Step 3: DC = DC SIDES are congruent

The proof is using Side-Angle-Side (SAS)

Look at the angles in step 2. These are the triangles you are proving congruency for: ΔADC ≡ ΔBCD

Jane wants to estimate the proportion of students on her campus who eat cauliflower. after surveying 39 students, she finds 4 w

stellarik [79]

Let $x$ be the number of students who eat cauliflower.

Therefore, $x=4$ .

Let $n$ be the total number of students surveyed.

Therefore, $n=39$

Thus, $\hat p$ $=\frac{4}{39} =0.10256$

Now, for 90% confidence level, from the table we know that $Z=1.645$ .

The formula for the interval range of proportion of students is :

$p= \hat p\pm Z\sqrt{\frac{\hat p(1-\hat p)}{n}}$

Plugging in the values we get:

$p=0.10256\pm 1.645\sqrt{\frac{0.10256(1-0.10256)}{39}}=0.10256\pm 0.04858=0.15114, 0.05398$

Thus, Jane is 90% confident that the population proportion p, for students who eat cauliflower in her campus is between 5.398% and 15.114% (after converting the answer we got to percentage).
