Which one of the following data sets has more than one mode?
A. {10, 20, 30, 30, 40, 50, 50}
B. {10, 20, 30, 40, 50, 70, 70}
C. {20, 20, 30, 30, 30, 40, 40}
D. {10, 20, 30, 40, 50, 60, 70}
From the given data sets, only option A has more than one mode (30 and 50),
so the correct answer is:
A. {10, 20, 30, 30, 40, 50, 50}.
We know that, A mode is a value in a dataset that appears most frequently.
To determine which data set has more than one mode, we need to find the sets that have multiple values that appear most frequently.
Let's examine each data set:
A. {10, 20, 30, 30, 40, 50, 50}
Mode(s): 30 and 50 (both appear twice)
B. {10, 20, 30, 40, 50, 70, 70}
Mode(s): 70 (appears twice)
C. {20, 20, 30, 30, 30, 40, 40}
Mode(s): 30 (appears three times)
D. {10, 20, 30, 40, 50, 60, 70}
Mode(s): None (each value appears only once)
From the given data sets, only option A has more than one mode (30 and 50),
so the correct answer is:
A. {10, 20, 30, 30, 40, 50, 50}.

Farmer Brown and Farmer Green were talking over their fence one afternoon. Farmer Brown said, "If you gave me one of your cows, we would have the same number of cows." Farmer Green said, "If you gave me one of your cows, I would have twice as many cows as you." How many cows do they have in total?
Farmer Brown has 5 cows and farmer Green has 7 cows
Step-by-step explanation:
Let the no. of cows farmer brown has be 'b'
Let the no. of cows farmer green has be 'g'
Given that,
B+1 = G-1
G = B + 2
G+1 = 2(B-1)
G+1 = 2B - 2
G = 2B -3
B + 2 = 2B - 3
2 + 3 = 2B - B
B = 5
G = B +2
G = 5 + 2
G = 7
Farmer Brown has 5 cows and farmer Green has 7 cows

What is the image of
(-6,9)
after a reflection over the y-axis?
Answer:
(6, 9 )
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), thus
(- 6, 9 ) → (6, 9 )
Reflection over the y-axis in mathematics changes the sign of the x-coordinate of a point while the y-coordinate remains unchanged. Therefore, the point (-6,9) reflects over the y-axis to become (6,9).
Explanation:In mathematics, a reflection over the y-axis is a geometrical transformation of a point in a two-dimensional space. When we reflect a point over the y-axis, the x-coordinate of that point changes its sign, while the y-coordinate remains the same.
Given the point (-6,9), after reflection over the y-axis, it will become (6,9). This is because the reflection changes the sign of the x-coordinate, turning -6 into 6, while the y-coordinate remains the same.

Jamie has a ladder that is 15 ft long. She wants to lean the ladder against a vertical wall so that the top of the ladder is 14 ft above the ground.
1A. Use trigonometry to find the angle formed between the ground and the ladder. Round to the nearest whole number
2A. For safety reasons Jamie wants the angle the ladder makes with the ground to be no greater than 75 degrees. Will the ladder be safe the way she has it positioned?
Answer:
1A. = 68.96 degrees.
2A. = YES
Step-by-step explanation:
Hi, to answer this question we have to apply:
sin (angle ) = opposite side / hypotenuse
Since the triangle formed is a right triangle ( see attachment), the hypotenuse is the length of the ladder (the longest side), and the opposite side to the angle is the distance between the top of ladder and the ground.
Replacing with the value given
sin x = 14/15
Solving for x
x = arcsin 14/15
x = 68.96 degrees. (1A)
Since the angle is lower than 75 degrees, the ladder is safe the way is positioned.

The answer is D
Step-by-step explanation:
You are basically looking for the area of this circle, the formula would be A=Pi*r^2. So plug the values in and it would be, A=3.14*400, we know the radius is 20 because the diameter is double that, and square the radius, this gives you 400.

Step-by-step explanation:
Multiply the altitude of the diamond times the length of one of its sides. The altitude is the distance between any two opposite sides of the diamond. So if the diamond has an altitude of 2 feet and its sides are each 3 feet long, its area is 2 * 3 = 6 feet squared.
4. The perimeter of a rectangle is 42 yards.
The difference of the length and width of
the rectangle is 7 yards. Find the length
and width.
Answer:
Step-by-step explanation:
Let width = x
Length = 7 + x
Perimeter = 42 yards
2*(length + width) = 42
2* ( 7 + x + x) = 42
7 + 2x = 42/2
7 + 2x = 21
2x = 21 - 7
2x = 14
x = 14/2
x = 7
Width = 7 yards
Length = 7 + 7 = 14 yards
Rectangle wxyz has the following coordinates w(1,1),x(5,1),y(5,4). What’s the missing coordinate for point z?
To find the missing coordinate for point Z of rectangle WXYZ, we apply the properties of rectangles with given coordinates W(1,1), X(5,1), and Y(5,4). Z shares its x-coordinate with W and its y-coordinate with Y, so the missing coordinate for Z is Z(1,4).
Explanation:To determine the missing coordinate for point z of rectangle WXYZ, we need to understand the properties of rectangles. A rectangle has four right angles, and opposite sides are equal and parallel. Coordinate geometry principles are applied here for pinpointing the missing point.
Given the coordinates of points W(1,1), X(5,1), and Y(5,4), we can deduce the coordinates of Z. Since WX is a horizontal line segment and WY is a vertical line segment, we can infer that X and Y have the same x-coordinate because they are both on the right side of the rectangle. Similarly, W and Z should have the same x-coordinate since they are on the left side. Since the x-coordinate of W is 1, so will be the x-coordinate of Z.
Also, because W and X have the same y-coordinate, we know that the top and bottom sides of the rectangle are horizontal. Y and Z, therefore, must have the same y-coordinate, which is 4, the y-coordinate of point Y.
Thus, the missing coordinate for point Z is Z(1,4).

- If the area of a square is multiplied by nine, the area becomes 16 square inches. Find the
length x of a side of the square,
Answer:
1⅓ inches
Step-by-step explanation:
Area = side² = x²
9(x²) = 16
x² = 16/9
x = 4/3 inches or 1⅓ inches
Final answer:
To find the side length x of the original square when the area multiplied by nine equals 16 square inches, solve the equation [tex]9 \times x^2 = 16[/tex], resulting in x being [tex]\frac{4} {3}[/tex] inches or approximately 1.33 inches.
Explanation:
If the area of a square is multiplied by nine and becomes 16 square inches, we can write the equation as
[tex]9 \times x^2 = 16[/tex], where x is the length of a side of the square.
To find the length of the side x, we first divide both sides of the equation by 9 to isolate [tex]x^2[/tex]:
[tex]x^2 = \frac{16}{9}[/tex]
Then, we take the square root of both sides to solve for x:
x = [tex]\frac{4} {3}[/tex] or approximately 1.33 inches.
So the length x of a side of the original square is [tex]\frac{4} {3}[/tex] inches.

A basketball player makes 70% of his free throws the random numbers below represent 20 trials for a simulation let the numbers 0 to 6 represent a made free throw and let 7 to 9 represent a missed free throw use this simulation to estimate the probability that the player makes both free throws. (5,5) (0,6) (9,6) (7,4) (9,1) (7,3) (0,4) (9,3) (2,9) (1,4) (6,8) (5,3) (1,7) (1,7) (1,8) (3,5) (7,2) (2,1) (0,6) (1,8)
Answer:
Step-by-step explanation:To estimate the probability that the player makes both free throws based on the given simulation results, we can analyze the number of successful free throws (numbers 0 to 6) in each trial. From the provided data, we can identify the trials where both free throws were successful (made), indicated by the numbers 0 to 6 occurring twice in a row. Let's examine the data:(5,5) (0,6) (9,6) (7,4) (9,1) (7,3) (0,4) (9,3) (2,9) (1,4) (6,8) (5,3) (1,7) (1,7) (1,8) (3,5) (7,2) (2,1) (0,6) (1,8)Based on this data, we can see that the combinations where both free throws were made (0 to 6 occurring twice in a row) are:
(5,5) (1,8)Therefore, there are 2 trials out of 20 where the player made both free throws.To estimate the probability, we can divide the number of trials where both free throws were made (2) by the total number of trials (20):Probability = Number of successful trials / Total number of trials
Probability = 2 / 20
Probability = 0.1Therefore, based on this simulation, the estimated probability that the player makes both free throws is 0.1 or 10%.
The probability that the player makes both free throws is 55%.
Given data:
To estimate the probability that the player makes both free throws, count the number of trials where both free throws were made and divide it by the total number of trials.
Looking at the given random numbers, the pairs (5,5), (0,6), (9,6), (7,4), (9,3), (2,9), (1,4), (6,8), (5,3), (3,5), and (7,2) represent made free throws.
On counting the number of trials where both free throws were made, there are 11 pairs.
Since there are 20 total trials, the estimated probability of the player making both free throws is:
11/20 = 0.55
Hence, the estimated probability that the player makes both free throws is 0.55 or 55%.
