The proportion of selling times is 0.35
From the question, we have
Selling Time___ Frequency
0 10____________3
10 20__________ 4
20 30__________ 6
30 40__________ 4
40 50__________ 3
Proportion of selling times in sample above that are less than 20 days :
total frequency = (3 + 4 + 6 + 4 + 3) = 20
Selling time which is less Than 20 days :
(0 - 10) = 3
(10 - 20) = 4
Total = (3 + 4) = 7
Proportion = selling time less Than 20 days / total frequency
= 7 / 20
= 0.35
Addition:
The phrase "the addition" refers to combining two or more numbers. Adding two numbers is indicated by the plus sign (+), therefore adding three is written as three plus three. Additionally, the number of times the plus symbol (+) is used is up to you. For example, 3 + 3 + 3 + 3. Mathematical addition is a crucial component of the learning curriculum for kids. In primary school, students learn simple addition sums such as one-digit facts, Math addition sums, and double-digit Math addition sums. One of the most fundamental and interesting Math concepts for elementary school children is addition sums. Math is a fascinating subject, and children first learn basic mathematical concepts like adding numbers in their early years.

Answer:
a = 38 degrees
Step-by-step explanation:
ok that line is equal to 180 degrees
180 of the line subtract 52 degrees and 90 degrees equal the missing angle
52 + 90 = 142
180 - 142 = 38
a = 38
Answer:
Step-by-step explanation:
Hello!
Convert 55% to a decimal by dividing it by 100.
55 ÷ 100 = 0.55
Next, multiply the total amount of ounces of water by this decimal.
32 × 0.55 = 17.6
Finally, subtract the amount of ounces that person drank from the total number of ounces before they drank.
32 - 17.6 = 14.4
ANSWER:
14.4 ounces of water are left in the glass.
