Option C is correct, the set of vectors is linearly dependent because one of the vectors is the zero vector.

What is Matrix?

A matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns.

To determine if the set of vectors is linearly independent, we need to check if any of the vectors can be expressed as a linear combination of the others.

Let's consider the first vector [8 -6 4].

If we try to express this vector as a linear combination of the other vectors, we get:

[8 -6 4] = a[12 -9 6] + b[0 0 0]

where a and b are constants.

We can immediately see that this equation has infinite solutions, because the third component of the second vector is zero, which means we can choose any value for b and still satisfy the equation.

Therefore, the set of vectors is linearly dependent.

Hence, Option C is correct, the set of vectors is linearly dependent because one of the vectors is the zero vector.

1A. We draw five cards at random with replacement, keeping track of whether or not each card in the sequence is a club. Find the probability of the following sequence: Club, Not Club, Club, Not Club, Not Club, i.e. CNCNN.
B. Notice that all sequences of 5 cards with exactly two clubs have the same probability. Based on this fact and your result in a), find the probability of getting exactly 2 clubs in a sequence of 5 cards drawn at random with replacement from a 52 card deck.

Answers

Answer:

135/512

Step-by-step explanation:

In a deck of card, there are 13clubs.

A deck of card contains 52cards

Total clubs = 13cards

Probability of selecting a club and replacing is expressed as P(C) = total number of clubs/total card

P(C) = 13/52 = 1/4

q = 1-p

q = 1-1/4

q =3/4

Let X be probability function used is a binomial distribution formula expressed as:

Since 5cards is drawn at random, n = 5

P(X = x) = nCx q^(n-x)p^x

P(X = x) = 5Cx 3/4^(5-x)•(1/4)^x

The probability of the sequence is expressed as:

P(X = x) = 5Cx 3/4^(5-x)•(1/4)^x

x is the number of clubs present

b) To find the probability of getting exactly 2 clubs in a sequence of 5 cards drawn at random with replacement from a 52 card deck, we will substitute x = 2 into the probability function in (a) a shown;

P(X = 2) = 5C2•3/4^(5-2)•(1/4)^2

P(X = 2) = 5C2•3/4^(3)•(1/4)^2

P(X = 2) = 5C2•27/64•(1/16)

P(X = 2) = 5C2•27/1024

P(X = 2) = 5!/(5-2)!2!•27/1024

P(X = 2) = 5!/3!2!•9/1024

P(X = 2) = 5×4×3!/3!2•27/1024

P(X = 2) = 5×4/2•27/1024

P(X = 2) = 10•27/1024

P(X = 2) = 135/512

Hence the probability of getting exactly 2 clubs in a sequence of 5 cards drawn at random with replacement from a 52 card deck is 135/512

If 8 tennis balls cost $24, how much do 12 tennis balls cost?


Answers

Answer:

36

Step-by-step explanation:

half of 8 is 4 so half of 24 is 12 and 12 plus 24 is 36

Answer:

$36

Step-by-step explanation:

First divide the $24 to find how much each tennis ball costs.

24 / 8 = 3

Then multiply 3 (the cost per tennis ball) by 12 (the amount of tennis balls)

3 x 12 = 36

Answer: 9/16

Explanation: When dividing by a fraction, we can change

the division sign to multiplication and flip the second fraction.

So 3/8 ÷ 2/3 means the same thing as 3/8 · 3/2.

So when dividing by a fraction, we can just multiply

by the reciprocal of that fraction or that fraction flipped.

Now multiplying across the numerators and denominators, we have 9/16.

The quantity demanded x of a certain brand of DVD player is 3000/week when the unit price p is $485. For each decrease in unit price of $20 below $485, the quantity demanded increases by 250 units. The suppliers will not market any DVD players if the unit price is $350 or lower. But at a unit price of $525, they are willing to make available 2500 units in the market. The supply equation is also known to be linear. (a) Find the demand equation. p(x) = (b) Find the supply equation. p(x) = (c) Find the equilibrium quantity and the equilibrium price. PLEASE help I am totally lost on this

Answers

Answer:

a) Demand equation :[tex]y=-\frac{2}{25}x+725[/tex]

b) Supply equation : [tex]y=\frac{7}{100}x+350[/tex]

C) The equilibrium quantity and the equilibrium price are 2500 and $ 525 respectively

Step-by-step explanation:

We are given that  For each decrease in unit price of $20 below $485, the quantity demanded increases by 250 units.

Since decrease in unit price of $20 increase demand by 250 units

So, Slope =[tex]\frac{-20}{250}=\frac{-2}{25}[/tex]

We are given that The quantity demanded x of a certain brand of DVD player is 3000/week when the unit price p is $485.

Now for demand equation:

Use point slope form : [tex]y-y_1=m(x-x_1)[/tex]

So, [tex]y-485=\frac{-2}{25}(x-3000)\\y=-\frac{2}{25}x+725[/tex]

a)So, Demand equation : [tex]y=-\frac{2}{25}x+725[/tex]

Now to find supply equation

We have two points (0,350) and (2500,525)

[tex](x_1,y_1)=(0,350)\\(x_2,y_2)=(2500,525)\\y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\y-350=\frac{525-350}{2500-0}(x-0)\\y-350=\frac{7}{100}x\\y=\frac{7}{100}x+350[/tex]

b) So, Supply equation : [tex]y=\frac{7}{100}x+350[/tex]

Now to find equilibrium quantity and price equate demand and supply equation

[tex]-\frac{2}{25}x+725=\frac{7}{100}x+350\\725-350=\frac{7}{100}x+\frac{2}{25}x\\x=2500[/tex]

So, equilibrium quantity = 2500

To find equilibrium price substitute equilibrium quantity in any equation

[tex]y=\frac{7}{100}x+350\\y=\frac{7}{100}(2500)+350\\y=525[/tex]

C) The equilibrium quantity and the equilibrium price are 2500 and $ 525 respectively

The line shown represents the amount of money left on a gift card, y, after Mina buys lattes. After buying 2 lattes, she has $2 left. What is an equation of the line in point- slope form?​

Answers

Answer:

[tex] y - 2 = -3(x - 2) [/tex]

Step-by-step explanation:

Given that after she buys 2 lattes, she has $2 left, this represents a point on the line in the graph, which is (2, 2).

Point-slope form of equation for a line is given as [tex] y - b = m(x - a) [/tex]. Where,

(a, b) = a point on the line

m = slope

The equation of the line in point-slope form is given by the formula, [tex] y - b = m(x - a) [/tex], where,

(a, b) = coordinates of a point on the line.

[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

We already have values for (a, b) = (2, 2), let's find the slope (m).

Using (2, 2) and any point on the line, such as (0, 8), we can find the slope as follows:

[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8 - 2}{0 - 2} [/tex]

[tex] = \frac{6}{-2} [/tex]

[tex] m = -3 [/tex]

Now we know that a = 2, b = 2 , and m = -3. Let's plug in this values into the point-slope equation as shown below:

[tex] y - b = m(x - a) [/tex]

[tex] y - 2 = -3(x - 2) [/tex]

A coffee manufacturer is interested in the mean daily consumpiton of regular-coffee drinkers and decaffeinated-coffee drinkers. A random sample of 50 regular-coffee drinkers showed a mean of 3.84 cups per day. A sample of 40 decaffeinated-coffee drinkers shoed a mean of 3.35 cups per day. The sample stnadard deviation for those drinking regular coffee is 1.20 cups per day an 1.36 cups per day for those drinking decaffeinated coffee. Assume the population standard deviations are euql. At the 5% significance level, is the mean daily consumption of reglar-coffee drinkers greater than that of decaffeinated-cofee? Find the p-value for this hypothesis test.

Answers

Answer:

The decision rule is  

Reject the null hypothesis

The conclusion

There is sufficient evidence to conclude that mean daily consumption of regular-coffee drinkers greater than that of decaffeinated-coffee.

The p-value  is  [tex]p-value  = 0.03682 [/tex]

Step-by-step explanation:

From the question we are told that

   The first sample size is  [tex]n_ 1 = 50[/tex]

   The first sample mean is [tex]\=x_1  =  3.84[/tex]

The first sample standard deviation is  [tex]s_1  = 1.26[/tex]

    The second sample size is  [tex]n_2  =  40[/tex]      

   The second  sample mean is   [tex]\=x_2  =  3.35 [/tex]

    The second sample standard deviation is [tex]s_2  =  1.36[/tex]

    The level of significance is  [tex]\alpha =  0.05[/tex]

The  null hypothesis is  [tex]H_o  :  \mu_1  = \mu_2[/tex]

The alternative hypothesis is  [tex]H_a  :  \mu_1  >  \mu_2[/tex]

Generally the test hypothesis is mathematically represented as

 [tex]t =  \frac{( \= x_1 - \= x_2 ) - 0}{ \sqrt{ \frac{s^2_1 }{n_1}  + \frac{s^2_2}{n_2} } }[/tex]

=>  [tex]t =  \frac{( 3.84 - 3.35  ) - 0}{ \sqrt{ \frac{1.26^2 }{50}  + \frac{1.36^2}{40} } }[/tex]

=>   [tex]   t =  1.789  [/tex]      

Generally the p-value is mathematically represented as

      [tex]p-value  =  P(t > 1.789)[/tex]

From the z table  

    [tex]\Phi (1.789) =  0.03682[/tex]

So

   [tex]p-value  =  P(t > 1.789) =  0.03682 [/tex]

From the value obtained we see that [tex]p-value < \alpha[/tex] hence

The decision rule is  

Reject the null hypothesis

The conclusion

There is sufficient evidence to conclude that mean daily consumption of regular-coffee drinkers greater than that of decaffeinated-coffee

 

     

Find the slope of the line

Answers

Answer: m = -3/2

Step-by-step explanation: In algebra, we use the word slope

to describe how steep a line is and slope can be found using

the ratio rise/run between any two points that are on that line.

Let's start from the point (0, 0).

From this point, we go down 3 units and to the right 2 units.

So our rise is -3 and our run is 2.

So our slope or rise/run is -3/2.

The variable that's used to represent slope is m.

So we say that m = -3/2

Answer:

-3/2

Step-by-step explanation: Rise 3 from the first (lower) dot then run 2 to the higher dot. Its negative because it is going down from left to right.
