Avni designs a game in which a player either wins or loses 4 points during each turn. Which equation represents all numbers of p

Ierofanga [76]

Answer:

C |p| = 4

Step-by-step explanation:

If a player wins 4points during each turn, then, the total points will be +4points

If the player looses 4points, total points lost will be -4points

The total number of point p the player can have will be represented as;

|p| = 4 (since is both positive and negative 4 )

Note that the nodulus of a variable will return both positive and negative value of that variable

Could someone please help me answer this math question

Greeley [361]

Explanation

5 students got 6 mark each, 4 students got 7 marks each, 7 students got 8 marks each, 10 students got 9 marks each and 4 students got 10 marks each.

(a) Range is the difference of highest mark and lowest mark. Here, the highest mark is 10 and lowest mark is 6.

So, the range of mark $= 10-6 = 4$

(b) Total number of students in the group $= 5+4+7+10+4= 30$

(c) Mean is the simple average. So, for finding the Mean, we will divide the total marks obtained by all students by the total number of students.

Total marks obtained by all students

$= (6*5)+(7*4)+(8*7)+(9*10)+(10*4)\\ \\ = 30+28+56+90+40 = 244$

So, the Mean mark of the group $=\frac{244}{30}=8.13333....$

One day, eleven babies are born at a hospital. Assuming each baby has an equal chance of being a boy or girl, what is the probab

Andrews [41]

You only need to consider the situations where 10 or 11 of the babies are girls, then subtract those probabilities from 1. This will give probability that any other number up to 9 of the babies are girls.

Use binomial theorem.
$P(x=k) = (nCk) p^k (1-p)^{n-k}$

n = 11
k = 10,11
p = 1/2

$P(x=10) = 11 (\frac{1}{2})^{11} = \frac{11}{2048} \\ \\ P(x=11) = 1(\frac{1}{2})^{11} = \frac{1}{2048} \\ \\ P(x \leq 9) = 1 - \frac{11}{2048} - \frac{1}{2048} \\ \\ P(x \leq 9)=\frac{2036}{2048} = \frac{509}{512}$
