Find the probability of rolling divisors of 8.
In a class of 30 students, 12 have a cat and 19 have a dog. There are 6 students who
do not have a cat or a dog. What is the probability that a student chosen randomly
from the class has a dog?
Answer:
19/30
Step-by-step explanation:
30 students
12 have cat , 19 have dog , 6 no cat or dog
P dog = 19 have dogs/30 students total = .633333...
The likelihood that a randomly selected student in the class owns a dog is 19/30.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Let A be the event that a student has a dog. Then, the number of students having a dog is 19, and the total number of students is 30.
The number of students having neither a cat nor a dog is 6. Therefore, the number of students having at least a cat or a dog is:
12 (number of students having a cat) + 19 (number of students having a dog) - 6 (number of students having neither a cat nor a dog) = 25
Thus, P(A) = number of students having a dog / total number of students = 19/30.
Therefore, the probability that a student chosen randomly from the class has a dog is 19/30.

The range for Set B is greater than the range for
Set A
The median for Set A is greater than the median
for Set B.
The ranges for both sets are equal
The medians for both sets are equal.
Answer:
The median for Set A is greater than the median
for Set B.
Step-by-step explanation:
From the boxplot attached, we can deduce the following :
Median (vertical line in between the box on a boxplot).
Median, set A = 30
Median, set B = 29
Range = (Maximum - Minimum. Value)
Set A :
Maximum = 35 ; Minimum = 21
Range = 35 - 21 = 14
Set B :
Maximum = 37 ; Minimum = 24
Range = 37 - 34 = 3
Hence, from the options, the only correct statement is The median for Set A is greater than the median for Set B.

What is the volume of a sphere with a diameter of 9.1m, rounded to the nearest tenth of a cubic meter?
Answer: V≈ 394.57m³
Step-by-step explanation:
The volume of the given sphere is approximately 391.3 m³.
What is the volume of a sphere?The formula for the volume of a sphere is given by (4/3)πr³, where r is the radius of the sphere.
Given that the diameter of the sphere is 9.1 m, we can calculate the radius by dividing the diameter by 2:
Radius = Diameter / 2 = 9.1 m / 2 = 4.55 m
Now, we can substitute the radius value into the formula and calculate the volume:
Volume = (4/3) x π x (4.55 m)³
Volume = 4.18 x (4.55 m)³
Volume = 4.18 x (4.55³)
Volume = 4.18 x 93.859
Volume = 391.34482
Rounded to the nearest tenth of a cubic meter,
Volume = 391.3 m³
Therefore, the volume of the sphere is approximately 391.3 m³.

Lines A and B are parallel
m<6 = [?]°
Answer:
Im pretty sure its 55
Step-by-step explanation:
So it adds to a 180 degree angle
When lines A and B are parallel m<6 (the measure of angle 6) is 55° .
If lines A and B are parallel and ∠4 and ∠6 are consecutive interior angles, then we can use the property that consecutive interior angles add up to 180°.
Given that ∠4 is 125°, we can substitute this value into the equation :
∠4 + ∠6 = 180°.
125° + ∠6 = 180°.
To find the measure of ∠6, we can subtract 125° from both sides :
∠6 = 180° - 125°.
∠6 = 55°.
Therefore, m<6 (the measure of angle 6) is 55°.
