PLEASE HELP ASAP!!!!
Veseljchak [2.6K]

Answer:

Step-by-step explanation:

R(0,0)

A=((0+2a)/2,(0+2b)/2)=(a,b)

S(2a,2b)

B=((2a+2c)/2,(2b+2d)/2)=(a+c,b+d)

T(2c,2d)

C=((2c+2c)/2,(2d+0)/2)=(2c,d)

V(2c,0)

D=((2c+0)/2,(0+0)/2)=(c,0)

R(0,0)

slope of AB=(b+d-b)/(a+c-a)=d/c

slope of DC=(d-0)/(2c-c)=d/c

slope of AD=(0-b)/(c-a)=-b/(c-a)

slope of BC=(d-b-d)/(2c-a-c)=-b/(c-a)

Dalgliesh the detective fancies himself a shrewd judge of human nature. In careful tests it has been discovered that he is right
Dafna11 [192]

Answer:

The probability that Jones is lying is 6/7

Step-by-step explanation:

First we will list out 2 different cases when the outcome is a lie

1.probability that Jones tells lies is = 0.6 and probability that dalgiliesh analyses it correctly is 0.8

So the probability that dagliesh correctly analyses that he is telling lies is 0.8*0.6=0.48

2.Probability that Jones tells truth is 0.4 and if dagliesh analyses it incorrectly (which has a probability of 0.2) the outcome(as analysed by dagiliesh) is a lie

So probability that dagliesh analyses Jones truth as a lie is 0.2*.0.4=0.08

Total probability of outcome being a lie is 0.48+0.08=0.56

But we need the probability of Jones actually saying a lie which is nothing but 0.48/0.56= 6/7

How to get everything to one side of the inequality for 3+4/x>=(x+2)/x
Ksenya-84 [330]

Answer:

2x+2\geq 0

Step-by-step explanation:

Given:

The given inequality is.

3+\frac{4}{x} \geq \frac{x+2}{x}

Solution:

Simplify the given expression.

3+\frac{4}{x} \geq \frac{x+2}{x}

Multiply by x both side of the equation.

x(3+\frac{4}{x}) \geq x(\frac{x+2}{x})

Simplify.

3x+\frac{4x}{x} \geq x(\frac{x+2}{x})

3x+4\geq x+2

Rewrite the equation as.

3x+4-x-2\geq 0

2x+2\geq 0

Therefore, 2x+2\geq 0 is the simplest form of the given expression.

A golfer wants to determine if the type of driver she uses each year can be used to predict the amount of improvement in her gam
Black_prince [1.1K]

Answer:

The type of driver

Step-by-step explanation:

The term known as '' response variable'' is use in describing a variable that changes when you alter an examination or a test. Just like its name implies, it is the ''response'' that one gets when the other variable that is the Explanatory Variable are being altered.

In this question, the golfer will have to be changing the type of drivers that she is using in order to be able to know whether these changes in drivers will increase her game performance. Hence, the Explanatory Variable is the type of driver in which the golfer changes which is being use to define the performance of the golfer.
