Answer:

y = 4x - 31

Step-by-step explanation:

Parallel slope (m) = 4

(5, -11)

y - y1 = m(x - x1)

y + 11 = 4(x - 5)

y + 11 = 4x - 20

y = 4x - 31

The world famous gambler from Philadelphia, Senor Rick, proposes the following game of chance. You roll a fair die. If you roll a 1, then Senor Rick pays you $25. If you roll a 2, Senor Rick pays you $5. If you roll a 3, you win nothing. If you roll a 4 or 5, you must pay Senor Rick $10, and if you roll a 6, you must pay Senor Rick $15. Is Senor Rick loco for proposing such a game? Explain.

Answers

Answer:

You lose $0.833 while Rick gains $0.833, and so Rick is not Loco

Step-by-step explanation:

There are six numbers on a dice. Thus, probability of rolling exactly one number = 1/6

Probability of rolling two is 2/6.

Rolling a 1 pays $25, and probability = 1/6

Rolling a 2 pays $5,and probability = 1/6

Rolling a 3 pays $0, and probability = 1/6

Rolling a 4 or 5 pays -$10, and probability = 2/6

Rolling a 6 pays -$15, and probability = 1/6

Thus,lets calculate the expected value;

EV = (25 × 1/6) + (5 × 1/6) + (0 × 1/6) + (-10 × 2/6) + (-15 × 1/6)

EV = - $0.833

This means you lose $0.833 while Rick gains $0.833, and so Rick is not Loco.

Step-by-step explanation:

4. E=-6

-9

multiply both sides by the LCM=-9

-9 × (e) = -6×-9

-9

therefore the LCM will cancel I out the denominator

e = -6×-9

e= -54

5. K =2

multiply through by the LCM=12

12×(k)=2×12

cross out

k=24

6. m=-10

multiply through by the LCM=6

6×m=-10×60

cross out

m=-60

Kat is interested in getting chickens so she can have fresh eggs. Before she buys her chickens, she wants to find the mean number of eggs each one will lay. She begins by randomly selecting 40 chickens from a large poultry farm and counts how many eggs each one lays within one month. She finds the mean to be 24.8 eggs with a standard deviation of 6.9 eggs. The resulting interval is (22.96, 26.64). Which of the following correctly interprets the 90% confidence interval for the true mean number of eggs chickens from this poultry farm lay within one month?

90% of all chickens at this farm lay between 22.96 and 26.64 eggs.
In repeated sampling, 90% of the time the true mean number of eggs chickens at this farm lay is 24.8.
Kat can be 90% confident that the constructed interval (22.96, 26.64) captures the true mean number of eggs chickens from this farm lay.
In repeated sampling, 90% of the time the true mean number of eggs laid by chickens from this farm will be captured within the interval (22.96, 26.64).

Consider the two points (1, 6) and (4, 48).

a. Is there a line that goes through these two points? How do you know? If there is one, what is the equation of the line going through these

Answers

Answer:

Yes there is a line

y=14x-8

Step-by-step explanation:

use slope formula and incorporate the slope into the coordinates

Answer:

[tex]y = 14x - 8[/tex]

Step-by-step explanation:

. Using euclid postulate,

" any two points can be on a line".

So yes a line can be formed

Use the linear equation in ppont-slope form

[tex]y = mx + b[/tex]

where m is slope, b is the y intercept.

We can find the slope of the points first.

[tex]48 - 6 = 42[/tex]

[tex]4 - 1 = 3[/tex]

[tex] \frac{42}{3} = 14[/tex]

Our slope is 14.

We can plug in any two coordinates to find b.

[tex]14(1) - b = 6[/tex]

[tex] - b = - 8[/tex]

So our equation is

[tex]y = 14x - 8[/tex]

If my initial angle is 30 degrees, what is the negative coterminal angle?

Answers

Answer:

Step-by-step explanation:

Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side. For example 30° , −330° and 390° are all coterminal.

Answer:

-330°

Step-by-step explanation:

Coterminal angles have a difference of 360° or multiples of 360°.

Negative coterminal angle with 30° is:

30° - 360° = -330°
