Answer: Blood type will be A when event "A" happened and event "B" did not happen. Blood type will be B when event "A" did not happened and event "B" happened. Blood type will be AB when both events happened and blood type will be O when both events did not happen.
Step-by-step explanation:
S={AntiA reacts; AntiA does not react; AntiB reacts; AntiB does not react}
If AntiA reacts and AntiB reacts = AB (A∩B)
If AntiA does not react and AntiB does not react= O (A'∩B')
If AntiA reacts and AntiB does not react= A (A∩B')
If AntiA does not react and AntiB reacts= B (A'∩B)
Answer: 4.5%
Step-by-step explanation:
Percentage will be calculated as:
No of players with height below 74/ total number of players x 100
From the question, Only one player has height of below 74
Total number of heights recorded is from 22 players
% = 1/22 × 100
0.04545 x 100
= 4.5%
I hope this helps.
A = area of triangle + area of rectangular + half of the circle area
_________________________________
triangle area = 1/2 × base × height
triangle area = 1/2 × 3 × 5 = 15/2 = 7.50
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆
rectangular area = length × width
rectangular area = 6 × 5 = 30
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆
circle half area = 1/2 × pi × radius^2
circle half area = 1/2 × 3.14 × 3^2
circle half area = 1.57 × 9
circle half area = 14.13
_________________________________
A = 7.50 + 30 + 14.13
A = 51.63 m^2
Answer:
Step-by-step explanation:
way_1:
according to the condition the probability for the 1st computer is 8/10=4/5;
for the 2d computer is 7/9. Then the final probability is P=4/5 * 7/9=28/45;
way_2:
the required probability can be calculated according the formula:
then
Answer:
Around 11.9
Step-by-step explanation:
5.3n + 7.75 = 70.85
First subtract 7.75 on both sides.
5.3n = 63.1
Then divide both sides by 5.3
n=11.9 (I rounded to the nearest tenth.)
