Step-by-step explanation:

y2-y1/x2-x1

-1-(-4)/3-7

3/-4

y=mx+b

For the y coordinate it can be either -4,or -1

-4=3/-4x+b

b=13/4

Answer:

I think its b

do you have to times it?

Answer:

b. normally distributed with a mean of $1200 and a standard deviation of $40.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Population:

Skewed to the right, mean 1200, standard deviation [tex]\sigma = 400[/tex]

Sample of 100 days:

By the Central Limit Theorem:

Approximately normal

Mean 1200

Standard deviation [tex]s = \frac{400}{\sqrt{100}} = 40[/tex]

The correct answer is given by option b.

Answer:

7ft/1yd ⋅1yd/3ft

Step-by-step explanation:

To use unit analysis to convert 7 feet to yards

Using unit analysis

1 yard = 3 feet

Hence

3 feet = 1 yard

7 feet = x yard

Cross Multiply

3 feet × x yard = 7 feet × 1 yard

We can represent this as

7 feet/1 yard × 1 yard/3 feet

The correct Option is :

7ft/1yd ⋅1yd/3ft

Answer:

45°

Step-by-step explanation:

here's your solution

=> we know that sum of both angle is equal

180°

=> because both angle are co-interior angle

=> let the unknown angle be x

=> so, X + 135° = 180°

=> x= 180 - 135

=> 45°

Answer: Graphed points I used, (-2,0), (0,-2), and (-3,-1)

Step-by-step explanation:

The graph of given function is attached below.

The given function is,

                          [tex]f(x)=-|x+2|[/tex]

We have to draw the graph of above function.

When [tex]x=-2[/tex] ,  [tex]f(-2)=0[/tex]

When [tex]x=-4[/tex] , [tex]f(-4)=-|-4+2|=-2[/tex]

When [tex]x=0[/tex], [tex]f(0)=-2[/tex]

Thus, We have points [tex](-2,0),(-4,-2)[/tex] and [tex](0,-2)[/tex]

It is stated that there is [tex]200\%[/tex] the markup on match day i.e.

The selling price of the ticket is

[tex]\Rightarrow S.P.=30+30\times 200\%\\\Rightarrow S.P.=30+30\times 2=30+60\\\Rightarrow S.P.=\$90[/tex]

Answer:

YZ = 13 units

Step-by-step explanation:

By intersecting chords theorem in a circle,

YA × AZ = WA × AX

By substituting the values of each segment in the formula,

10 × AZ = 6 × 5

AZ = [tex]\frac{30}{10}[/tex]

AZ = 3 units

Therefore, YZ = AZ + AY

YZ = 3 + 10

YZ = 13 units

Answer:

Pigeonhole Principle

Step-by-step explanation:

From series {1,2......2n} ; we need to select 'n + 1' integers.

Even integers series from above series = {2,4,6..........2(n-1), 2n}

Odd integers series from above series = {1,3,5........2(n-2), 2n-1}

So, we can choose only n odd integers from the series. Hence, if we choose n+1 integers, atleast one of them have to be even integer.

The moment generating function of each random variable is;

M(t) = (1/(1 - 1.5t))^(2), t < 2/3

Answer:

SD[X + Y] = 3

Step-by-step explanation:

For ease of differentiation, let's rewrite the M(t) function as;

M(t) = (1 - (3/2)t)^(-2)

Let's find the first derivative of the function;

M'(t) = 3(1 - (3/2)t)^(-3)

To get E[X], we will put 0 for t to get;

E[X] = 3(1 - (3/2)0)^(-3)

E[X] = 3

Now,let's find the second derivative of M(t)

M"(t) = (27/2)(1 - (3/2)t)^(-4)

At,t = 0, we will get E[X²]

Thus;

E[X²] = 27/2

Now, Var[X] = E[X²] - (E[X])²

Var[X] = (27/2) - 3²

Var[X] = 9/2

We are told that the times X and Y are independently and identically distributed. Thus, the sum of their variances is equal to the variance of their sum. This is expressed as;

Var[X + Y] = 9/2 + 9/2

Var[X + Y] = 9

Now,we know that square root of variance is standard deviation. Thus;

SD[X + Y] = √9

SD[X + Y] = 3
