Imagine selecting a US high school student at random. Define the random variable X = number of languages spoken by the randomly selected student. The table below gives the probability distribution of X, based on a sample of students from the US Census at School database.
What is the expected average number of languages a student knows?
Find and interpret the standard deviation for the data.
Answer:
Expected value = 1.457
Standard deviation = 0.671
Step-by-step explanation:
Given the data:
Language (X) : 1 ____ 2 ____ 3 ____ 4 ____ 5
P(X) _____0.630 _ 0.295 _0.065_0.008_0.002
Expected value :
ΣX*P(x) = (1*0.630)+(2*0.295)+(3*0.065)+(4*0.008)+(5*0.002)
= 1.457
Standard deviation : sqrt(Var(x))
Var(X) = Σx^2p(x) - E(x)
Var(X) = (1^2*0.630)+(2^2*0.295)+(3^2*0.065)+(4^2*0.008)+(5^2*0.002) - 1.457^2
= 2.573 - 1.457^2
= 0.450151
Standard deviation = sqrt(0.450151) = 0.6709329
= 0.671
Average Expected number of languages known by student, ie Expected Value = 1.457 ; Standard Deviation of Data = 0.45015
A] Expected Value represents the average, calculated by summing products of outcomes & their corresponding probabilities. E (X) = X . P (X) , where X are events & P (X) are corresponding probabilities.
E (X) = 1 (0.63) + 2 (0.295) + 3 (0.065) + 4 (0.008) + 5 (0.002) = 1.457
B] Standard Deviation denotes the measure of dispersion, spread around average. Formula = [tex]X^2 P (X) - [ E (X) ]^2[/tex]
1 (0.63) + [tex]2^2[/tex] (0.295) + [tex]3^2[/tex] (0.02,65) + [tex]4^2[/tex] (0.008) + [tex]5^2[/tex] (0.002) - [tex](1.457)^2[/tex]
= 2.573 - (1.457)^2 = 0.45015

HELPPPPP I WILL GIVEBRAINLIEST TO FASTEST. find the number if 12/13of it is 24.
Answer:
26
Step-by-step explanation:
You would do 24 × 13/12
This would be 26
Answer:
26
Step-by-step explanation:
First, we convert the question into an equation.
12/13x = 24.
We multiply both sides by 13 to get rid of the fraction that is on the left side of the equation.
12x=312.
Dividing both sides by 12, we get:
x = 26

Step-by-step explanation:
Consider a sequence given by the formula f(n)=3n-1 starting with n=1. Generate the first 5 terms of the sequence
Answer:
The first 5 terms are 2, 5, 8, 11, 14.
Step-by-step explanation:
You use the formula to find out each term.f(n)=3n-1 starting with n=1. If n=1 that is the 1st term, if n=2 that is the 2nd term, and so on. n means what number term it is. Now to find each term: n=1: f(1)= 3(1)-1= 3-1= 2 The 1st term is 2n=2: f(2)= 3(2)-1= 6-1= 5 The 2nd term is 5n=3: f(3)= 3(3)-1= 9-1=8 The 3rd term is 8n=4: f(4)= 4(3)-1= 12-1= 11 The 4th term is 11n=5: f(5)= 5(3)-1= 15-1= 14 The 5th term is 14So the first 5 terms are 2,5,8,11,14
A hockey player needs to shoot a puck 55 meters from his current location to his opponent's goal to score a goal. After the shot, the puck is 120 centimeters from his opponent's goal. If there are 100 centimeters in 1 meter, how many meters did the puck travel?
Answer:
The puck traveled 53.8 meters.
Step-by-step explanation:
Currently, the player is 55 meters away from the opponent's goal.
After the shot, the puck is 120 centimeters = 1.2 meters from the opponents goal.
So, this means that the puck traveled 55 - 1.2 = 53.8 meters.

Step-by-step explanation:
Determine whether the underlined numerical value is a parameter or a statistic. Explain your reasoning. A survey of 32 out of 50 in a basketball game showed 20.5% enjoyed the game.
Answer: statistic.
Step-by-step explanation:
A parameter is a measure of characteristic in a population.
A statistic is a measure of characteristic in a sample.
Given: A survey of 32 out of 50 in a basketball game showed 20.5% enjoyed the game.
Since group of 32 games out of 50 is representing a sample here.
So, 20.5% is the measure of sample, i.e. it is a statistic.
Brendan Gan is about to drive to Kuala Lumpur from Johor Bahru. The distance from Johor Bahru to Kuala Lumpur is 330 km. Brendan's car can drive 60 miles using 1 gallon of petrol The current petrol costs are RM1.85 per liter. Calculate the total petrol cost for Brendan to drive from Johor Bahru to Kuala Lumpur. Use: (1 gallon = 4.5 liters 1 mile = 1.61 km Round up answer to 2 decimal places (8 marks)
Answer:
He will spend RM 28.44.
Step-by-step explanation:
Each mile has 1.61 km.
So the distance, in miles, is given by:
[tex]\frac{330}{1.61} = 205[/tex]
For 60 miles, he uses 4.5 liters. So, for 205 miles, he will use:
[tex]\frac{205*4.5}{60} = 15.375[/tex]
For the trip, he uses 15.375 liters. Each liter costs RM 1.85. So he will spend:
[tex]15.375*1.85 = 28.44[/tex]
He will spend RM 28.44.

a. Rolling a number less than 9
b. Rolling a multiple of 3
c. Rolling a number greater than 6
Answer:
a.) likely
b.) unlikely
c.) equally
Step-by-step explanation:
A.) ~~~ there are more numbers less than 9 than numbers greater than or equal to 9, so rolling this is likely
B.) ~~~ There are only 4 multiples of 3, so rolling this is unlikely.
C.) ~~~ There are an equal amount of numbers greater than 6 and less than or equal to 6, so the chances of this are 50/50, or equal

Question: The two angles below form a linear pair and are therefore supplementary solve for X. (Geometry)
Answer:
x = 29
Step-by-step explanation:
(2x - 13)° + (7x - 68)° = 180° (linear pair angles add up to 180°)
Solve for x
2x - 13 + 7x - 68 = 180
Add like terms
9x - 81 = 180
Add 81 to both sides
9x = 180 + 81
9x = 261
Divide both sides by 9
x = 261/9
x = 29

In ΔEFG and ΔYXZ, m∠F ≅ m∠X and m∠E ≅ m∠Y. If m∠E = 62° and m∠X = 80°, what is the measure of ∠Z?
Triangles EFG and YXZ, in which triangle YXZ is larger than EFG.
{Please look at the comments for the answer}
A) 38°
B) 62°
C) 80°
D) 142°
Answer: A) 38°
Step-by-step explanation:
Given: In ΔEFG and ΔYXZ, m∠F ≅ m∠X and m∠E ≅ m∠Y. If m∠E = 62° and m∠X = 80°.
So, m∠F = m∠X = 80°
m∠Y = m∠E = 62°
By angle sum property , the sum of all angles in a triangle is 180 degrees.
In ΔXYZ ,
∠ X + ∠Y + ∠Z = 180°
⇒ 80°+ 62°+ ∠Z = 180°
⇒ 142°+∠Z = 180°
⇒ ∠Z = 180°-142°
⇒ ∠Z = 38°
Hence, the correct option is A) 38°.
Answer:
the answer is A, 38 degrees
