Answer:
option A
2/4 = 0.5
Step-by-step explanation:
Given in the questions that,
number of student in chess club = 4
P(B) = 4/10
number of student in karate club = 6
P(A) = 6/10
number of students who are both in chess and karate club = 2
P(A∩B) = 2/10
total number of students 10
Formula to use
<h3>P(A/B) = P(A∩B) / P(B)</h3><h3> = 2/10 / 4/10</h3><h3> = 2/4</h3><h3> = 1/2</h3><h3> = 0.50</h3>
Answer:
120kg, 72kg and 8kg
Step-by-step explanation:
Given the ratios 15:9:1
total ratio = 15+9+1 = 25
For the ratio of 15
Share = 15/25 * 200
Share = 3000/25
Share = 120kg
For the ratio of 9
Share = 9/25 * 200
Share = 1800/25
Share = 72kg
For the ratio of 1
Share = 1/25 * 200
Share = 200/25
Share = 8kg
If a diagram has a scale of 1:100, that means that the real thing is 100 times larger. To find how long the real thing is, that means that we need to multiply the length on the diagram by 100. 100 * 15 is 1500. But, that is 1,500 cm. To convert it into meters, we need to divide by 100. That's because there's 100 centimeters in every meter. 1500/100 is 15, which means that the actual length of the car park is 15 meters.
L = B + 105
H = L + 24.....H = B + 105 + 24 ...H = B + 129
H + L + B = 324
(B + 129) + (B + 105) + B = 324
3B + 234 = 324
3B = 324 - 234
3B = 90
B = 90/3
B = 30 <==Bart's marbles
L = B + 105
L = 30 + 105
L = 135 <=== Lisa's marbles
H = B + 129
H = 30 + 129
H = 159 <=== Homer's marbles
