</span>Perry surveyed 60 students at her school.
=> 0.45 of the students said that their favorite subject is math
=> 0.45 x 100 = 45%
Thus, 45 % of 60:
=> 60 * .45 = 27
35% of the student said their favorite is science:
=> 35% / 100 = 0.35
=> 35% 0f 60 equals:
=> 60 * .35 = 21
Thus, 27 – 21 = 6 of the student said that they love math over science.

Answer:
0.912
Step-by-step explanation:
<em>The complete question is attached.</em>
<em />
"OR" in probability means "ADDITION". So we find the individual probabilities and "ADD" them.
P(Plan A) would be the total people for plan A (add up column of Plan A) divided by total number of people [add up all the numbers].
Looking at the table, we have:
P (Plan A) = 38/68
Now,
P(40-49 Group) can be found by adding up the row of 40-49 age group and dividing by the total. So, we have:
P(40 - 49 Group) = 24/68
Now, adding up both:
38/68 + 24/68 = 62/68 = 0.912
Answer:
x=23°
Step-by-step explanation:
93°+(3x+18)°=180°
93°+3x+18°=180°
111°+3x=180°
3x=180°-111°
3x=69°
x=69°:3
x=23°
