In many state lotteries you can choose which numbers to play. Consider a common form in which you choose 5 numbers. Which of the

following strategies can improve your chance of winning? If the method works, explain why. If not, explain why using appropriate statisics terms.
Will choosing the numbers that did come up in the most recent lottery drawing improve your chances of winning?

A) No, because each number drawn is dependent on the previous drawings, so this set of numbers is more likely in the next drawing if it has yet to be drawn.

B) Yes, because each number drawn is equally likely and indendent of the others, so this set of numbers is just as likely as any other in the next drawing.

C) No, because each number drawn is equally likely and indendent of the others, so this set of numbers is just as likely as any other in the next drawing.

Answer this question with a clear explanation to be marked as Brainiest ✨✨✨✨✨✨✨✨
Nina [5.8K]

Answer:

C

Step-by-step explanation:

A, B and D are all only a few digits long and can be expressed as the ratio of two integers, where at least one is even:

A = -6/16 = -3/8, so it's rational

B = 7.0398 = 35199/5000, so it's rational

D = 6,907 = 13814/2, therefore rational

C, on the other hand is irrational.

If we simplify the surd √8, we get 2√2. The 2's on the top and bottom can now cancel out, giving us √2, which is irrational. [There's a proof but it's kinda long].

From 10:00 am to noon, the rise in temperature is 4 degrees C, and from 3:00 pm to 5:00 pm, the fall in temperature is 6 degrees
lyudmila [28]

Answer:

(a) 2 degree celsius per hour

(b) 3 degree celsius per hour.

Step-by-step explanation:

From the question,

(a) Avearge rate of rise in temperature per hour(T') = Rise in temperature(T)/Time required for the rise(t).

T' = T/t.................... Euqation 1

Rise in temperature (T) = 4 degree celsius, t = 10.00 am to noon = 2 hours.

Substitute into equation 1

T' = 4/2

T' = 2 degree celsius per hour.

(b) Also,

Average rate of fall in temperature per hour (T') = Fall in temperature (T)/Time(t)

T' = T/t

Given: T = 6 degree celsius, t = 3:00 pm to 5:00 pm = 2 hours

T' = 6/2

T' = 3 degree celsius per hour

Which unit rate corresponds to the proportional relationship shown in the graph?
Evgen [1.6K]

Answer:

1.5 cm/s​

Step-by-step explanation:

The unit rate is the same as the slope.

To find the slope, we use the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}

Using our points, we have

m = (9-0)/(6-0) = 9/6 = 3/2 = 1.5 cm/s

What is an equation for the line that passes through (-2,-3) with a slope of -1/2?
Crazy boy [7]

Answer:

C

Step-by-step explanation:

To write the equation of a line use the point slope form of a line substituting m = -1/2 and the point (-2,-3).

y -y_1 = m(x-x_1)\\y --3=-\frac{1}{2}(x--2)\\y+3 = -\frac{1}{2}(x+2)

Convert to standard form by applying the distributive property and rearranging the terms.

y + 3 = -\frac{1}{2}(x+2)\\y+3 = -\frac{1}{2}x -1\\2y + 6 = -x -2\\x+2y + 6 = -2\\x + 2y = -8

The equation x +2y = -8 is the same equation as 4y + 2x = -16 just doubled----> 2x + 4y = -16
