In the Cash Now lottery game there are 8 finalists who submitted entry tickets on time. From these 8 tickets, three grand prize

alexgriva [62]

Answer:

The number of ways is $\left n} \atop {}} \right. P_r = 336$

Step-by-step explanation:

From the question we are told that

The number of tickets are $n = 8$

The number of finalist are $r =3$

Generally the number of way by which this winners can be drawn and arrange in the order of $1^{st} , \ 2nd , \ 3rd$ is mathematically represented as

$\left n} \atop {}} \right. P_r = \frac{n\ !}{(n-r) !}$

substituting values

$\left n} \atop {}} \right. P_r = \frac{ 8!}{(8-3) !}$

$\left n} \atop {}} \right. P_r = \frac{ 8* 7*6*5*4*3*2*1}{ 5*4*3*2*1}$

$\left n} \atop {}} \right. P_r = 336$

Please help.. I’m stuck on this question

s2008m [1.1K]

Answer: The answer is 1

Step-by-step explanation: The distance between -7 and -3 is 4 then half the distance in between -7 and -3 is going to be -5 because we just clarified that the distance between -7 and -3 is 4 so we did 4/2 and got 2 so we can figure out whats the distance between each point. Now that we figured that out we can determine what value the blue dot is if the value between each point is 2 then we can make out what the rest of the points on the line. If we from -3 to the blue point that would be 1.

Find the equation of the midline of the function y = 2 sin(1∕4x) – 3.

Aneli [31]

<h3>Answer: A) y = -3</h3>

Explanation:

The general sine equation is

y = A*sin(B(x-C)) + D

where the D variable directly determines the midline. In this case, D = -3, so that corresponds to a midline of y = -3

The sine curve oscillates going up and down, passing through this middle horizontal line infinitely many times. See the graph below.
