Answer: 0.3023
Step-by-step explanation:
86 band members
26 are senior, 17 plays trumpet. If 4 are seniors and play trumpet, we solve this using the bayes theorem of conditional probability.
Probability of choosing band member that plays trumpet =17/86 = 2/43.
Probability of choosing a senior that plays trumpet = 4/26
Probability that a chosen member is a senior given that he plays trumpet = (2/43)/(4/26)
= 0.3023.
Answer:
C. (f – g)(x) = –2x – 2
Step-by-step explanation:
(f – g)(x) = f(x) – g(x)
= (–5x – 4) – (–3x – 2)
= –2x – 2
Answer:
32
Step-by-step explanation:
In 1 gallon, there are 128 ounces.
Divide 128 by 4 and get 32.
I would think A because regular quadrilaterals have 90-degree angles.
The correct equation of the scaled figure is given by 6/3 = 4/a
<h3>Scaling</h3>
Scaling is the process of either increasing or decreasing the size of a figure by a factor.
From the diagram attached, Figure f is a scaled copy of Figure e. Figure e is decreased to produce figure f, hence:
- AB/XY = CD / WZ
- 6/4 = 3 / a
- 6/3 = 4/a
The correct equation of the scaled figure is given by 6/3 = 4/a
