Help! I need help with question 2 and 3. Thanks.

Answer:

x=24

Step-by-step explanation:

Answer:

a) The probability of getting a seven is 4/52

b) At least one of the cards is a seven=0.2813

c) The probability that none of them are seven=  0.7187

d) The probability that two out the four cards is a seven= 0.043

Step-by-step explanation:

A deck contains 52 cards containing 4 sets of 13 cards . Each set has a seven card in it. Thus there are 4 seven cards in a deck of 52 cards.

a) The probability of getting a seven is 4/52=0.0769

b) At least one of the cards is a seven=

1- P(no seven)

= 1- 4C0 * 48C4/ 52C4= 1- 0.7187= 0.2813

c) The probability that none of them are seven=4C0 * 48C4/ 52C4=  0.7187

d) The probability that two out the four cards is a seven= First card is seven * second Card is seven * two cards are not seven

= 4/52* 3/51*48/50= 0.0769*0.0588*0.96= 0.043

Answer:

10.1m

Step-by-step explanation:

1ft = 0.305m

Answer:

50 mph

Step-by-step explanation:

Answer:

300

Step-by-step explanation:

Let x = cost of desktop computer; then x - 250 = cost of laptop computer

converting % to decimals, 9% = 0.09 and 6% = 0.06

Then, 0.09x + (x - 250)0.06 = $300

0.09x + 0.06x - 15 = $300

0.15x = $315

x = $2100

then x - 250 = $1850

Proof: $2100•0.09 + 1850•0.06 = $189 + $111 = $300

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

[tex]3x+4=17x-10[/tex]

Subtract 4 from both sides:

[tex]3x+4-4=17x-10-4[/tex]

[tex]3x=17x-14[/tex]

Subtract 17x from both sides:

[tex]3x-17x=17x-14-17x[/tex]

[tex]-14x=-14[/tex]

Divide both sides by -14:

[tex]\frac{-14x}{-14}=\frac{-14}{-14}[/tex]

[tex]x=1[/tex]

Answer:

1

Step-by-step explanation:

Step 1:

3x + 4 = 17x - 10

Step 2:

4 = 14x + 10

Step 3:

14 = 14x

Answer:

x = 1

To create the slope 8, you would have to do the rise over run:8/1. which means u go up 8 units and to the side one unit and you keep doing that. And since the y-intercept is -8, then you start your first point at -8 and continue to go up.

The graph is attached below:

Graphing basic functions like linear functions and quadratic functions is easy. The basic idea of graphing functions is

Identifying the shape if possible. For example, if it is a linear function of the form f(x) = ax + b, then its graph would be a line; if it is a quadratic function of the form f(x) = ax2 + bx + c, then its a parabola.

finding some points on it, by substituting some random values of x and finding the corresponding values of y by substituting each value into the function.

For graphing quadratic function also, we can find some random points on it. But this may not give a perfect U-shaped curve. This is because, to get a perfect U-shaped curve, we need where the curve is turning. i.e., we have to find its vertex. After finding the vertex, we can find two or three random points on each side of the vertex and they would help in graphing the function.

Given:

slope= 8

y- intercept = -8

So, the equation can be

y= mx+ c

y= 8x - 8

Answer:2,2

Step-by-step explanation:

I guess

The solution is (1,2)

Step-by-step explanation:

 7x + 10y = 27

 x - 10y = -19                                                                                                                    +--------------------

8x = 8

Divide by 8 on both sides

x = 1

To find y substitute any of the equations to 1

7(1) + 10y = 27

7 + 10y = 27

Substract 7 from both sides

10y = 20

Divide by 10

y = 2

Answer:

4

Step-by-step explanation:

The intersection A n(B n C) is an empty set: {∅}

For two sets A and B.

A n B is defined as the intersection between A and B, so it is the set of common elements between A and B.

Here we have:

Then:

A n (B n C)

First, we have:

B n C = {6}

6 is the only common element between B and C.

And 6 does not belong to A, then:

A n (B n C) = {∅}

Which is an empty set.

Answer:

[tex]P(C\ and\ D) = 153\%[/tex]

Step-by-step explanation:

Given

[tex]P(C) = 98\%[/tex]

[tex]P(D) = 88\%[/tex]

[tex]P(C\ or\ D) = 33\%.[/tex]

Required

[tex]P(C\ and\ D)[/tex]

In probability, the relationship between the given parameters and the required parameter is:

[tex]P(C\ and\ D) = P(C) + P(D) - P(C\ or\ D)[/tex]

Substitute values in the above formula

[tex]P(C\ and\ D) = 98\% + 88\% - 33\%[/tex]

[tex]P(C\ and\ D) = 153\%[/tex]

No, it can't be a probability

Because [tex]P(C\ and\ D) > 100\%[/tex]

To find the range, subtract the smallest from the biggest number.

The outlier is most commonly the biggest or smallest number. Obviously it is 236 in this situation.

To find how much the outlier increases the range, you need to find out the range WITH and WITHOUT the outlier.

Without the outlier: 39

With the outlier: 190

Then you subtract 190 - 39 because you are trying to find out how much MORE RANGE the outlier makes.

The answer is 151.

THEREFORE, The outlier increases the range by 151.
