In a class of students, the following data table summarizes how many students have a
brother or a sister. What is the probability that a student chosen randomly from the
class does not have a sister?
Has a brother Does not have a brother
Has a sister
3
12
Does not have a sister
2.
Answer:
Step-by-step explanation:
total students = 27
students do not have a brother probability = 13/27
students do not have a sister probability = 12/27
= 4/9
Hope this is correct :)
The probability that a student is chosen randomly from the class does not have a sister is 0.375.
The probability that a student is chosen randomly from the class Has a brother is 0.208.
The probability that a student is chosen randomly from the class does not have a brother is 0.7916.
The probability that a student is chosen randomly from the class Has a sister is 0.625.
What is the probability?Probability is the branch of mathematics, which discusses the occurrence of a random experiment.
First, we need to calculate how many total students there are.
Once we have the total we have to divide the number in the category that we want by the total number of students to calculate the probability of randomly getting a student in that category.
Total Students = 3 + 12 + 2 + 7 = 24 students
The probability that a student is chosen randomly from the class does not have a sister is;
[tex]= \dfrac{2+7}{24}\\\\=\dfrac{9}{24}\\\\=0.375[/tex]
The probability that a student is chosen randomly from the class Has a brother is;
[tex]= \dfrac{3+2}{24}\\\\=\dfrac{5}{24}\\\\= 0.208[/tex]
The probability that a student is chosen randomly from the class does not have a brother is;
[tex]= \dfrac{7+12}{24}\\\\=\dfrac{19}{24}\\\\= 0.7916[/tex]
The probability that a student is chosen randomly from the class Has a sister is;
[tex]= \dfrac{3+12}{24}\\\\=\dfrac{15}{24}\\\\= 0.625[/tex]

As apart of her physical fitness training, Kaylee cycled at 30km/h and then jogged at 8 km/h. She spent 2 hours working out and covered a distance of 49 km. How long did Kaylee spend at each activity?
Answer:
for cycling, time is 1.5 hours
for hogging time is 0.5 hour.
Step-by-step explanation:
speed of cycling = 30 km/h
speed of jogging = 8 km/h
total time = 2 hrs
total distance, D = 49 km
Let the time for cycling is t, so that time time for jogging is 2 - t .
distance = speed x time
49 = 30 x t + 8 (2 - t)
49 = 30 t + 16 - 8 t
33 = 22 t
t = 1.5 hour
So, time for cycling is 1.5 hours and time for jogging s 0.5 hr.

Answer:
C
Step-by-step explanation:
What we have to do here is to select a point from the graph
We can select the point (-8,1)
What this simply mean is that when x = -8, y = 1
Now, let us take a look at the second third option
f(-8) will be the cube root of -(-8) , with 1 subtracted from it
The cube root of 8 is simply 2, subtracting 1 from it will yield 1
so that makes the point (-8,1) valid

Q - A vehicle with an empty fuel tank has a mass of 1050kg. One litre of petrol has a mass of 737g. What is the minimum amount of whole litres of petrol that would cause the total mass to exceed 1100kg?
Please help me.
Answer:
The minimum balance is 68 liters
Step-by-step explanation:
Let the number of liters of petrol required be x
Given that One litre of petrol has a mass of 737g, x liters will have a mass
= 0.737x kg
Recall that 1 kg = 1000g
Since the empty fuel tank has a mass of 1050kg
The total mass = 1050 + 0.737x IN kg
For the total mass to exceed 1100kg, then
1050 + 0.737x > 1100
0.737x > 1100 - 1050
0.737x > 50
Divide both sides by 0.737
x > 50/0.737
x > 67.84260516

James is 12 years old and his brother is 16. Which ratio represents James' age to his brother's age 4 years from now?
Answer:
16/20=1/4
Step-by-step explanation:
James is 1/4 younger then his brother
4:5 is the ratio which represents James' age to his brother's age 4 years from now.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that James is 12 years old
James brother is 16 years old.
We need to find the ratio which represents James' age to his brother's age 4 years from now.
After 4 years the James age is 12+4, 16 years
After 4 years the James brother age is 16+4, 20years
The ratio of James' age to his brother's age is 16/20
4/5
Hence, 4:5 is the ratio which represents James' age to his brother's age 4 years from now

Hi, there your answer is C or D and the second page is C
Step-by-step explanation:
In the circle below, EG is a diameter and EF is tangent at E. Suppose mEF = 124°. Find the following. Does anyone know this?
Answer:
Step-by-step explanation:
If EG is a diameter, then arc EFG is a semicircle and its measure is 180. Arc FG then is 180 - 124 = 56. Since angle FEG is an inscribed angle and the arc it cuts off is arc FG, then the measure of the inscribed angle is half the measure of the arc it cuts off...so angle FEG is 28 degrees. Keep that in mind; we'll need it in a sec.
If HE is tangent to the circle at E, then angle HEG is a 90 degree angle. Adding that to angle FEG will give you angle FEH. Angle FEH = 90 + 28 = 118
Solve the equation
1 . J + -2 = -22
J + -2 = -22
Adding a negative number changes the equation to subtract ruin:
J - 2 = -22
Now add 2 to both sides to get the answer:
J = -20
Collect like term
J= -22 - 2
J= - 20
