Answer:
Step-by-step explanation:
hello :
the area is : A=(b×h)/2 b=2x and h= 2x-3
A=2x(2x-3)/2
A=x(2x-3)
A=2x²-3x
Answer:
Solution given:
time [t]=3years
principal [p]=Rs2400
rate[r]=?
simple interest [S.I]=Rs 576
we have
S.I=ptr/100
576=2400*3*r/100
576=72r
r=576/72
r=8%
now
principal [p]=Rs 4200
time[t]=2years
rate[r]=8%
simple interest [S.I]=?
we have
S.I= ptr/100=4200*2*8/100=Rs 672
<u>The</u><u> </u><u>required</u><u> </u><u>interest</u><u> </u><u>is</u><u> </u><u>Rs</u><u> </u><u>6</u><u>7</u><u>2</u><u>.</u>
Answer:
Intersection: {w, 7, y}
Union: {a, m, w, u, 7, y, g}
Step-by-step explanation:
The intersection of two or more sets are the elements they have in common, that means the elements that are in all the sets at the same time.
For example, "a" is in A but not in B, that's why is not in the intersection. On the other hand, "w" is in both sets, so it's in the intersection.
The union are all the elements that are in one set or the other, but we don't add the element twice if it's in both sets.
For example, "a" is in A so we add it to the union. "w" is in A so we add it to the union but it's also in B, we don't add it again because it is already in the union.
Answer:
0.8015 = 80.15% probability that the student has the flu
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Has high temperature.
Event B: Has the flu
Probability of a student having high temperatures:
90% of 35%(have the flu)
12% of 100 - 35 = 65%(do not have the flu). So
Probability of having high temperatures and the fly?
90% of 35%, so
If a student has a high temperature, what is the probability that the student has the flu?
0.8015 = 80.15% probability that the student has the flu
