Answer:

The answer to your question is in the picture below

Step-by-step explanation:

y + 3/4x < 2

y+ 3/4x = 2

y = -3/4x +2

Interceptions (0,2) and (8/3, 0) It's a dotted line and we are interested in the area below the line

y - 1 ≥ 2x

y - 1 = 2x

y = 2x + 1 Interception, it's not a dotted line with interceptions (0,1) and (-1/2, 0), we are interested in the area up the line.

A used car dealer has 30 cars and 10 of them are lemons (i.e.~ mechanically faulty used cars), and you don't know which is which

Triss [41]

Answer: Hence, the probability that he will get at least one lemon is 0.70.

Step-by-step explanation:

Since we have given that

Number of cars = 30

Number of lemon cars = 10

Number of other than lemon cars = 30-10 = 20

According to question, he bought 3 cars,

we need to find the probability that you will get at least one lemon.

So, P(X≤1)=1-P(X=0)=1-P(no lemon)

Here, P(no lemon ) is given by

$\dfrac{20}{30}\times \dfrac{20}{30}\times \dfrac{20}{30}=(\dfrac{20}{30})^3$

so, it becomes,

$P(X\geq 1)=1-(\dfrac{20}{30})^3=1-(0.67)^3=0.70$

Hence, the probability that he will get at least one lemon is 0.70.

10 - 5 / 10 ^ 2 + 0.4 (4+0.2)

Alexus [3.1K]

PEMDAS

parenthesis, exponents, mult/division, add/subtract

parenthesis: 4+0.2= 4.2

exponents: 10^2= 10×10= 100

new equation: 10-5/100×0.4(4.2)

multiply/divide: 10-(1/20)×.4×4.2

10-(0.05)(0.4)(4.2)

10-0.002×4.2

add/subtract: 10-0.0084 = 9.9916

The director of admissions at Kinzua University in Nova Scotia estimated the distribution of student admissions for the fall sem

svlad2 [7]

Answer:

The expected number of admissions for the fall semester is approximately 1248 students.

Step-by-step explanation:

We are given the following information in the question:

Number of Students: 1,060 1,400 1,540

Probability: 0.61 0.11 0.3

Formula:

$\text{Expectation} = E(x) = \sum xP(x)$

Expected number of admissions for the fall semester =

$E(x) = \sum xP(x)\\= (1060\times 0.61) + (1400\times 0.1) + (1540\times 0.3)\\=1248.6$

Hence, the expected number of admissions for the fall semester is approximately 1,248 students.

vodomira [7]

There are several information's already given in the question. Based on those information's the answer can be easily deduced.
The equation given in the question is
T = 10x + 1000
When the ticket rate is increased to $15, the equation becaomes
T = 15x + 1000
4000 = 15x + 1000
15x = 3000
x = 200 tickets
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option or option "C".
