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
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

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

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.

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

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.

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
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.
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
