Answer:
A) 57%
B) 16%
C) 53%
D) 57%
Step-by-step explanation:
Let R1 be students that attend class regularly
R2 be students that don't attend class regularly
A be students that receives A's in class
A) From the question A/R1 =57%
P(A/R1) = 0.57
B) From the question students that receive As that does not attend lectures regularly =16%
C) P(R2) = 1 -0.57 = 0.43
P(A) = P(A/R1) × P(R1) + P(A/R2)×P(R2)
P(A) = (0.57× 0.81) + (0.16×0
43)
P(A) = 0.46 + 0.0688= 0.53
The overall percentage that recieved A's = 53%
D) 57% recieved A's given that they attend class regularly.
Answer:
Step-by-step explanation:
f(x) = x²+3
f(a+1) = (a+1)²+3 = a²+2a+4
The value of p from the given equation is 136.
The given equation is p/4 - 15 = 19.
<h3>What is an equation?</h3>
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is solved as follows:
Transpose -15 to other side of the given equation
That is, p/4 = 19+15
⇒ p/4 = 34
Cross multiply 4 to 34
We get p = 34 × 4
⇒ p = 136
Therefore, the value of p from the given equation is 136.
