The probability that at least one of them will get scholarship is 0.93
<h3>How to determine the probability</h3>
The given parameters are:
P(Boy) = 0.75
P(Girl) = 0.72
The probability that at least one of them will get scholarship is calculated using
P = P(Boy only) or P(Girl only) or P(Both)
This is then calculated as:
P = 0.75 * (1 - 0.72) + 0.72 * (1 - 0.75) + 0.72 * 0.75
Evaluate the products
P = 0.21 + 0.18 + 0.54
Evaluate the sum
P = 0.93
Hence, the probability that at least one of them will get scholarship is 0.93

Grab some paper, a pencil, and a ruler. Make a 6 by 6 square
Step-by-step explanation:
Given that:
a = 2ˣ
b = 2ˣ⁺¹ = 2ˣ * 2¹ = 2.2ˣ
Now,
{(8a³)/b²}
Substitute the value of x and y in expression then
= [{8(2ˣ)³}/(2.2ˣ)²]
= [(8*2³ˣ)/{2² * (2ˣ)²}]
= {(8*2³ˣ)/(4 * 2²ˣ)}
[since, (aᵐ)ⁿ = aᵐⁿ]
= {(2 * 2³ˣ)/2²ˣ}
= {(2 * 2²ˣ * 2ˣ)/2²ˣ}
[since (2a = a+a, that means 3x = 2x + x)]
= 2 * 2ˣ
= 2ˣ⁺¹
[since (aᵐ * aⁿ = aᵐ+ⁿ)]
<u>Answer:</u> Therefore, {(8a³)/b²} = 2ˣ⁺¹ .

Answer:
5 3/10
Step-by-step explanation:
You subtract 1 1/5 from the number (n).
(In equation) x = n - 1 1/5
Answer:
A= pi r(r+h2+r2)
Step-by-step explanation:
Multiply the radius by pi, then set that aside for a bit.
Square the height and the radius as well, then add those together. This is how it would look:
3.14 x 4 = 12.56
7 x 7 = 49 ; 4 x 4 = 16 ; 16 + 49 + 4 = 69 ; 69 x 12.56
I think this is the answer. Can't say I'm 100% sure, though.
