Answer:
25%
Step-by-step explanation:
Mrs. Loar has to grade 75 papers. Mrs. Holt is helping her grade. Mrs. Loar graded 60 papers and Mrs. Holt graded the rest.
Hence, the amount of papers Mrs Holy graded is = 75 - 60
= 15 papers
What percent of the papers did Mrs. Holt grade?
This is calculated as:
15/60 × 100 = 25%
Hence, Mrs Holy graded 25% of the papers

Answer:
0.12 (12%)
Step-by-step explanation:
Step 1: Given data
Probability of rain every day: 70% (0.7)
Step 2: Calculate the probability that it rains every day
The probability that it rains one day is independent of the probability that it rains another day. For independent events, we can calculate the probability that it rains every day by multiplying the individual probabilities. Since the individual probabilities are equal, this is the same as raising the individual probability to the number of days.
P = 0.7⁶ = 0.12
