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:
270
Step-by-step explanation:
<u>To solve this, we use the unitary method.</u>
Distance flown in 20 sec = 180
Distance flown in one sec = = 9
Thus, distance flow in 30 secs = 9 × 30 = 270
I think this is the answer. Hope its correct :)
Have a great day!
Mrs Wright's paycheck was $ 630
<u>Solution:</u>
Given that,
Mrs Wright spend on food =
Fraction spent on rent =
She spent 1/4 of the remainder on transportation
Remaining left with her = $ 210
Let the paycheck amount be "n"
Now, we know that, paycheck amount = used amount + left over amount
Here, left over amount = 210
Paycheck amount = 2/9 of paycheck on food + 1/3 of paycheck on rent + 1/4 of remainder on transportation + 210
Upon simplifying we get,
On simplification, we get
On adding fractions we get,
Hence, the paycheck amount is $630
