Answer:
If we convert the percentages into numbers of students, including the margin of error:
Group 1: 40-49 (earlier) (31%-39%)
Group 2: 21-30 (same) (16%-24%)
Group 3: 45-55 (later) (35%-43%)
Group 4: 3-12 (no opinion) (2%-10%)
Interval estimate for group 1 is 40-49 students, and for group 3 is 45-55 students. The earlier group 1 could persuade the no opinion group 4 to join them. This would change the interval to 43-61, compared to 45-55 for group 3. In percentages this comes to 34%-47% approx.
number of cards = 100
number less than 14 = {2,3,...,13} = 12
number perfect square = {4, 9, 16, 25, 36, 49, 64, 81, 100} = 9
so
a) probability = 12/100 = 3/25
b) probability = 9/100
Answer:
5/9
Step-by-step explanation:
Step 1:
15 + 12
Step 2:
27
Step 3:
15/27
Step 4:
15/27 = 5/9
Answer:
5/9

The scale of the drawing is 1 cm to 10 feet. This means, every 1 cm of the drawing represents 10 feet in actual.
The trees are 5.2 cm apart in the drawing. So according to the given scale, they will be 5.2 x 10 = 52 feet apart in actual.
So actual bushes be planted at a distance of 52 feet.
