Answer:
25%
Step-by-step explanation:
The (not mentioned in the question) set is: 6 7 8 9.
There are 4 total outcomes and only 1 favorable outcome, then the probability to pick a 9 is:
P(9) = favorable outcome/total outcomes
P(9) = 1/4 = 0.25 or 0.25*100 = 25%
Find The Solution(s) to (x+3)square=49. check all the apply
Answer:
-10, 4
Step-by-step explanation:
(x+3)^2=49
Take the square root of each side
sqrt((x+3)^2)=±sqrt(49)
x+3 = ±7
Subtract 3 from each side
x+3-3 = ±7 -3
x = ±7 -3
x = 7-3 =4
and
x = -7-3 = -10

£ represents 29 students in class
B represents students who have a brother
S represents students who have a sister
a) One student from the class is chosen at random. What is the probability that the student has a sister?
b)One of the students who has a brother is chosen at random. What is the probability that this student has a sister?
Answer:
a) One student from the class is chosen at random. What is the probability that the student has a sister?
S/£
b)One of the students who has a brother is chosen at random. What is the probability that this student has a sister?
BS/£²
Step-by-step explanation:
In the question, we are given the following values:
£ represents 29 students in class = Total number of students in the class.
B represents students who have a brother
S represents students who have a sister
The formula for probability = Number of events ÷ Number of possible outcomes.
a) One student from the class is chosen at random. What is the probability that the student has a sister?
Number of events = Number of students that have a sister = S
Number of possible outcomes = £ represents 29 students in class
The probability that the student has a sister = S/£
b)One of the students who has a brother is chosen at random. What is the probability that this student has a sister?
This is calculated as
The Probability of Students that have a brother and a sister = Probability of students that have a brother × Probability of student that have a sister.
Number of students that have a brother = B
Number of students that have a sister = S
The Probability of Students that have a brother and a sister = B/£ × S/£
= BS/£²

1. Calculate the slope between the two points (2,5) and (-3,-4).
To find the slope of thine that passes through these points, use the slope formula. It can be read as “slope equals the second y-coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate.”
So we have [tex]\frac{-4 - 5}{-3 - 2}[/tex] and this simplifies to -9/-5 or 9/5.
Remember, a negative divided by a negative is a positive.

What is the approximate area of the shaded sector in the circle shown below?
A. 31.7 cm^2
B. 5.76cm^2
C. 2.88cm^2
D. 126.7cm^2
Answer:it’s 31.7 cm^2
Step-by-step explanation:
The approximate area of the shaded sector is 31.7 cm² (Option A).
To find the area of the shaded sector, we need to calculate the fraction of the entire circle that the sector represents and then multiply it by the area of the whole circle.
The formula to find the area of a sector is given by:
Area of sector = (θ/360) * π * r²
where θ is the central angle and r is the radius of the circle.
In this case, the radius (r) of the circle is given as 11 cm, and the central angle (θ) is given as 30 degrees.
Let's calculate the area of the shaded sector:
θ = 30 degrees
r = 11 cm
Area of sector = (30/360) * π * 11²
= (1/12) * π * 121
= π * 10.0833...
Now, we can approximate the value of π as 3.14:
Area of sector ≈ 3.14 * 10.0833...
≈ 31.7 cm²
Therefore, the approximate area of the shaded sector is 31.7 cm².
The correct option from the given choices is A. 31.7 cm².

What is the value of x?
Answer:
19
Step-by-step explanation:
Subtract 10 from both sides, making the equation 2x=38. X means what your multipying the number by which means it is 38/2 which is 19.
Answer:
x=16
Step-by-step explanation:
The two angles are complementary, which means they must add to 90 degrees.
∠T+∠V=90
We know that ∠T is 2x+10, and ∠V is 48. Therefore, we can substitute thesae values in.
2x+10+48=90
Combine like terms by adding 10 and 48
2x+58=90
Now, we have to solve for x. To do this, we must get x by itself.
Firs,t subtract 58 from both sides
2x+58-58=90-58
2x=32
Divide both sides by 2
2x/2=32/2
x=16

The product of a number, x , and 18 113.4. Which equation and value of x represent this relationship
Answer:
The answer is..
18 = x (113.4)
x = 95.4
Step-by-step explanation:
The equation 18x = 113.4 represents the sentence " the product of a number, x, and 18 113.4." and the solution of the equation is the value of variable x is 6.29.
What is Algebra?Algebra is the estimation of mathematical representations, while logic is the manipulation of those symbols.
The given statement is "the product of a number, x, and 18 is 113.4"
According to the given question, translate the phrase into an algebraic form :
This relationship can be represented by the equation 18x = 113.4.
To find the value of x, we can solve this equation by dividing both sides by 18, which gives us x = 113.4/18 = 6.29.
Thus, the required equation is 18x = 113.4

Handy Dandy Grocery is having a sale this week. If you buy a 5−pound bag of apples for the regular price, you can get another bag for $1.59. If you buy a 5−pound bag of oranges for the regular price, you can get another bag for $2.59. Handy Dandy Grocery Regular price 5−pound bag of apples 2.99 5−pound bag of oranges 3.99 Part 1 out of 2 Enter an addition equation to find the discount for apples. Use a for apples. Which fruit has a greater discount?
Answer:
apples have greater discount
Step-by-step explanation:
This is a proportional relation given by;
For apples, it's;
1.59/2.99 = x/100
Where x is the amount the second bag of apples cost in relation to the first, so:
x = 1.59 * 100/2.99
x = 53.18
So,let's now find the discount of the second bag of apples from;
Discount = 100 - 49.83 = 50.17% discount
Similarly, for oranges;
2.59/3.99 = x/100
x = 2.59 * 100/3.99
x = 64.91
So,let's now find the discount of the second bag of oranges from;
Discount = 100 - 64.91 = 35.09%
Since apples have discount of 50.17% and oranges have discount of 35.09%, thus apples have greater discount

Which statement is true about Anja’s claim? She is incorrect; the histogram is skewed to the left because more data is on the left side. She is incorrect; the histogram is skewed to the left because there is more data on the right side. She is incorrect; the histogram is symmetrical because the right side is equal to the left side. She is correct; the histogram is skewed to the right because there is less data on the right side.
Answer:
D. She is correct; the histogram is skewed to the right because there is less data on the right side.
Step-by-step explanation:
I just did it on edge
Option D is correct. She is correct; the histogram is skewed to the right because there is fewer data on the right side.
How can you spot a skewed graph?
A skewed distribution is one in which one of the two sides is biased (either left or right). It's like a mountain tilting to one side (left or right).
Like the picture, a left skewed graph has an extended tail on the left side of the main peak. A right skewed graph features an extended tail on the right side of the main peak.
She is correct; the histogram is skewed to the right because there is fewer data on the right side.
Hence, option D is correct.
