Answer:
9
Step-by-step explanation:
Expected number of defective is given as :
N x P = np
Where = number of the sample drawn from the production lot
P= percentage of bulbs In The lot which are defective
N = 15
P = 60% = 0.60
So when we do the multiplication,
We have:
NP = 15x0.60
= 9
So in conclusion the expected value of defective bulbs in the sample is 9.

The y intercept is -7, the slope is 4
y=mx+b
m=slope b=y intercept
Answer:
y = 4x - 7
Step-by-step explanation:
y = mx + b

A roulette wheel has 38 slots numbered 1-36 and 0 and 00. Suppose you bet $1 on 4 numbers (1,2,3,4). If the ball lands on one of your 4 numbers you win $8, otherwise you lose $1. Suppose you play this game 80 times. This corresponds to drawing how many tickets at random?
Answer:
This corresponds to drawing 80 tickets at random.
Step-by-step explanation:
Since a roulette wheel has 38 slots numbered 1 - 36 and 0 and 00, and you play this game 80 times, it implies that you will need 80 tickets. Each play requires a ticket from which you will choose your four numbers. This is a game of chance, and like all games of chance, the outcome cannot be ascertained until after the play.
At random, this corresponds to drawing 80 tickets.
ProbabilityAccording to the question,
Number of slots in wheel = 38
Number of times game played = 80
Win = $8
Lose = $1
Even though a roulette wheel includes 38 slots designated 1 - 36 along with 0 as well as 00, if users start playing 80 times, they will require 80 tickets or coupons. Also, every game necessitates the purchase of a ticket from which you will select your four digits.
This represents a matter of chance, as well as the conclusion, like all situations of opportunity, cannot be known until well after the tournament has been completed.
Thus the response above is correct.

Answer:
So I believe we're looking for the best long term plan
the first plan is staight forward so lets look at the secod one
14 + .04 times X
so if you make more than 350 calls (or more than 35o mins worth of calling time) you'll be charged more than the first plan due to 350 calls will equal 14 dollars with makes the bill 28 dollars which equals out the second and first plan
A triangle has side lengths of 2x, 4x, and 5x inches. If the perimeter of this triangle is 44 inches, what is the value of x?
Answer:
4
Step-by-step explanation:
2x+4x+5x=44
11x=44
x=11
Value of the given x is 4 units
Given that;
Sides of perimeter = 2x, 4x, 5x
Perimeter of triangle = 44 inches
Find:
Value of x
Computation:
Perimeter of triangle = Sum of all sides
44 = 2x + 4x + 5x

In a building construction project, the on-time completion of the building requires the successive completion of a series of activities. Define E = excavation completed on time; and P[E] = 0.8 F = foundation completed on time; and P[F] = 0.7 S = superstructure completed on time; and P[S] = 0.9 Assume statistical independence among these events.
Answer:
The probability of the completion of the project on time is 0.504.
Step-by-step explanation:
The question is:
Define the event C : (project completed on time) in terms of E, F and S. Compute the probability P(C) operations will not be on time in terms of E, F and S.
Solution:
The events are:
E = excavation completed on time; P [E] = 0.8
F = foundation completed on time; P [F] = 0.7
S = superstructure completed on time; P [S] = 0.9
The event C denotes the completion of the project on time.
Compute the probability of event C as follows:
P (C) = P (E ∩ F ∩ S)
= P (E) × P (F) × P (S)
= 0.8 × 0.7 × 0.9
= 0.504
Thus, the probability of the completion of the project on time is 0.504.
Sand pouring from a chute forms a conical pile whose height is always equal to the diameter. If the height increases at a constant rate of 5 feet per minute, at what rate is the sand pouring from the chute when the pile is 10 feet high
Answer:
125π ft³/min
Step-by-step explanation:
Volume of a cone = 1/3πr²h
r is the radius
h is the height.
r = d/2
Volume = 1/3π(d/2)²h
Volume = 1/3π(d²/4)h
Volume = 1/3πd²h/4
Since the diameter is equal to height, hence d = h
V = 1/3πh³/4
V = 1/12πh³
dV/dt = dV/dh × dh/dt
Given
dh/dt = 5ft/min
dV/dh = 3/12πh²
dV/dh = πh²/4
Given h = 10ft
dV/dh = π(10)²/4
dV/dh = 25πft²
Next is to get dV/dt
dV/dt = 25π × 5
dV/dt = 125π ft³/min
Hence the rate at which the sand is pouring from the chute when the pile is 10 feet high is 125π ft³/min
150 families in Metropolis yield the accompanying data on length of residence in current homes. What is a point estimate for the mean of the sampling distribution of the difference between the 2 sample means?
Answer:
B. -15
Step-by-step explanation:
The question is incomplete, find the complete question attached. The point estimate of the mean is also known as the mean of the towns
Given the mean of two towns
xbarG for sample mean of Gotham = 35
xbarM for sample mean of Metropolis = 50
distribution of the difference between the 2 sample means = xbarG - xbarM
distribution of the difference between the 2 sample means = 35-50
distribution of the difference between the 2 sample means = -15
Hence option B is correct

Jacoby writes 1/12 page in 1/3 of a minute. How much time will it take Jacoby to write a full page?
Answer:
4 Minutes
Step-by-step explanation:
If 1/12th of a page is 1/3 of a minute, you have to ask what number do you multiply 1/12th by to equal 1?
12.
So then multiply both 1/12th and 1/3rd by 12. You get 12/12 and 12/3
12/12=1 page
12/3=4 minutes
So every 4 minutes he writes one page.
