Answer:
Probability chosen student received A in one or both = 0.191 (Approx.)
Step-by-step explanation:
Given:
Total number of student = 490
66 = received A in general chemistry
58 = received A in calculus
30 = received A in both general chemistry and calculus
Find:
Probability chosen student received A in one or both.
Computation:
Probability chosen student received A in one or both = 66/490 + 58/490 - 30/490
Probability chosen student received A in one or both = 94/490
Probability chosen student received A in one or both = 0.191 (Approx.)
Answer: x=65
step by step explanation:
since the two angles are linear pairs that would make the sum of the two angles equal out to 180 degrees (a straight line), therefore, the equation used would be 2x+50=180
to find x you must solve the equation 2x+50=180
work shown:
2x+50=180
2x=130
x=65
Answer: It can be calculated by using the formula of perimeter and by adding four sides
1) Perimeter= 2(L+B)= 8n+12
2) Perimeter= L+L+L+L= 4L= 8n+12
Step-by-step explanation:
As it is a square playground all its sides are equal
Perimeter of the sidewalk = 2(L+B)= 2(2n+3+0.5)= 2(2n+3.5)= 4n+7
Perimeter of the square playground= <em><u>2(L+B)</u></em>= 2(2n+3+2n+3)
<em>2(4n+6)= 8n+12-------------------------A</em>
Perimeter of the square playground<u><em>= L+L+L+L=4L</em></u> 42n+3+2n+3+2n+3+2n+3=<u><em>4(2n+3)= 8n+12------------------------B</em></u>
Answer:
9 servings
Step-by-step explanation:
4.5%.5=9 so the cook made 9 servings.
Answer:
27
Step-by-step explanation:
Pamela is 13 years younger than Jiri and the sum of their ages is 41, therefore (x=Jiri's age) (x-13) + x = 41) 2x-13=41 x=14. Pamela is 14 and Jiri is 27
