From the sample population of students with blond hair, what is the approximate value of the relative frequency of students with green eyes? A. 0.25 B. 0.33 C. 0.27 D. 0.07
Answers
Don't quote me on this but I think the answer is C. 0.27
The required approximate value of the relative frequency of students with green eyes is 0.27. Option C is correct.
From the sample population of students with blond hair, the approximate value of the relative frequency of students with green eyes is to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Number of students having green eyes with blond hair =21
Total number of students having blond hair = 78
relative frequency of students with green eyes = 21/78
= 0.27
Thus, the required approximate value of the relative frequency of students with green eyes is 0.27.

The hourly wages earned by 20 employees are shown in the first box-and-whisker plot below. The person earning $15 per hour quits and is replaced with a person earning $8 per hour. The graph of the resulting salaries is shown in plot 2. A box-and-whisker plot is shown. The number line goes from 7 to 15. The whiskers range from 8 to 15, and the box ranges from 8.8 to 10.2. A line divides the box at 9.5. Plot 1 A box-and-whisker plot is shown. The number line goes from 7 to 15. The whiskers range from 8 to 11, and the box ranges from 8.7 to 10. A line divides the box at 9.6. Plot 2 How does the mean and median change from plot 1 to plot 2? The mean and median remain the same. The mean decreases, and the median remains the same. The mean remains the same, and the median decreases. The mean and median decrease.
Answers
Answer:
The mean decreases, and the median remains the same.Step-by-step explanation:
Remember that a box plot is made by the quartiles of the distribution, the maximum value and the minimum value. So, from a box plot we can deduct the range, the median and the interquartile range.
In this case, the median remains the same at $9.5 per hour. The median is indicated by the middle line of the box, and you can observe that it doesn't change.
Now, the range of the data set decreases from 7 to 3.
On the other hand, the mean must decrease, because data greater than $11 doesn't exist in the box plot number 2, and the mean is a central measure sensible to those changes.
Therefore, the right answer is The mean decreases, and the median remains the same.

Find the value of x and y
Answers
Answer:
x = 45
y = 20
Step-by-step explanation:
Set the x-variables and y-variables with its corresponding ones, like so:
4x - 35 = 3x + 10
Subtract 3x from both sides:
x - 35 = 10
Add 35 to both sides:
x = 45
Solving for y:
2y - 5 = y + 15
Subtract y from both sides:
y - 5 = 15
Add 5 to both sides:
y = 20
Answer:
By vertically opposite angle
2y-5=y+15
y=20°
4x-35=3x+10
x=45°

3/14
Step-by-step explanation:
If you want to find the probability of a blue marble being drawn, I would add up the total amount of marbles, which is 4+3+7=14. There are 3 blue marbles out of the 14 total marbles, and as a fraction, that would be 3/14.

Step-by-step explanation:
Hi!
You would get -3.
You would use Pemdas to simplify the equation.
Pemdas is parenthesis exponents multiplication division additin and subtraction in the order to do them.
First, you would do the math in the parenthesis, which equals 7.
Then, you would use the exponent which would be 7 x 7 which is 49.
Next, you would use multiplication which is 2 times 5 which is 10.
Next, you would divide, which is 49 divided by 7 which equals 7.
Now, you go from left to right which would give you -3.

Given a square with two vertices of one side located at (-5. -3) and (-5, 12), in square units what is its area?
1. 847
2.704
3.479
4.225
Answers
Answer:
4. 225
Step-by-step explanation:
The distance between points (-5, -3) and (-5, 12) is the length of the side of the square. Since both points have an x-coordinate of -3, they lie on the same vertical line. The distance between them is |12 - (-3)| = |12 + 3| = |15| = 15. The side measures 15 units.
area = side^2
area = 15^2 = 225
Answer:
225
Step-by-step explanation:
Since the side length of the square is 15 units, a square has sides of the same length, therefore the other side lengths are also 15 units. A = b*h so 15*15=225

Find the diameter of the object.
A circular steering wheel with radius labeled 0.8 feet.
diameter:
ft
Answers
in order to find the diameter, you multiply the radius times 2.....so you would do 0.8 times 2 which equals 1.6
The diameter of the circular steering wheel is 1.6 feet
How to determine the diameter?The radius of the object is given as:
r = 0.8 feet
Multiply both sides by 2, to determine the diameter
d = 2 * 0.8 feet
Evaluate
d = 1.6 feet

There is a line that includes point (1,2) and has a slope of 10 what is equation in intercept form
Answers
Answer:
[tex]y=10x-8[/tex]
Step-by-step explanation:
Given: Point (1,2) lies on the line such that it's slope is 10.
To find: equation of line
Solution:
Let m be the slope of line and b be the y - intercept.
Here, slope is a number that describes the direction and the steepness of the line.
y-intercept is the y-coordinate of the point where the graph of the line intersects the y-axis.
Equation of line is [tex]y=mx+b[/tex]
Put [tex](x,y)=(1,2),m=10[/tex]
[tex]2=10(1)+b\\2=10+b\\b=2-10=-8[/tex]
So, equation of line is [tex]y=10x-8[/tex]

If you need 4 tables spoons of golden syrup to make 10 cupcakes, how many tables spoons of golden syrup will you need to make 4 cupcakes.
Answers
Answer:
1.6 tablespoons
Step-by-step explanation:
Let’s make a proportion
syrup/cupcakes=syrup/cupcakes
4 tablespoons are needed for 10 cupcakes and x tablespoons are needed for 4 cupcakes.
4/10=x/4
Now we have to solve for x. x is being divided by 4. To reverse this, multiply both sides by 4, because multiplication is the opposite of division.
4*4/10=x/4*4
The 4s on the right will cancel, so we are left with:
4/4*10=x
1.6=x
So, 1.6 tablespoons are needed for 4 cupcakes.

Two sides of a triangle are as follows: 2 centimeters and 5 centimeters. Describe the possible lengths of the third side
Answers
Answer:
3cm < Third side < 7cm
Thus third side can take any value between 3cm and 7 cm
(note: excluding 3 cm and 7 cm)
If the value are integral then possible values of third side are
4cm, 5cm,6cm
Step-by-step explanation:
This question can be solved using given by Triangle Inequality Theorem Given below.
Sum of two sides is always greater than value of third sideDifference of two sides is always less than value of third sideGiven two sides are 2cm, 5cm
Sum of two sides = (2+5)cm = 7 cm
Difference of two sides = (5-2) = 3 cm
Let the third side be X
thus according to Triangle Inequality Theorem
X < Sum of two sides of given triangle
X < 7cm -----1
X > Difference of two sides
X > 3cm ----1
combining expression 1 and 2 we have
3cm < X < 7cm
Thus third side can take any value between 3cm and 7 cm
(note: excluding 3 cm and 7 cm)
If the value are integral then possible values are
4c, 5cm,6c
