1. maria has broken three out of eight of her eggs for her science experiment. if she must use 80 eggs for her experiment, how many eggs can we expect her to break?
2. ms. ratliff surveys her 6th period to see what social media they prefer, and the results are recorded in the table. if ms. ratliff has 110 students, about how many can we predict would choose instagram?

	snapchat	threads	instagram	tiktok

Explanation:

Step1: Find broken egg proportion

Proportion = $\frac{3}{8}$

Step2: Calculate expected broken eggs

Expected = $60 \times \frac{3}{8} = 22.5$

Step3: Find Instagram preference proportion

Total surveyed = $7+5+9+6=27$; Proportion = $\frac{9}{27}=\frac{1}{3}$

Step4: Predict Instagram users

Prediction = $110 \times \frac{1}{3} \approx 36.67$ (Note: Original table numbers may have a typo; if total surveyed was 30, prediction would be 33. Assuming correct proportion calculation as per given numbers.)

Answer:

22.5
16.5
