Which better describes the data set, the mean or the median? Select the answer with the best explanation. A The median, because it is in the middle of the set. B The mean, because it is closer to most of the data values than the median is. C The mean, because it is the average of all the values of the set. D The median, because it is closer to most of the data values than the mean is.
Answers
Answer:
C
Step-by-step explanation:
The mean of the data describes the data set , because it is the average of all the values of the set
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the data set be represented as A
Now , the value of A is noted
And , the median of the data set is the middle term of the set
where the mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values
So , the average values of the set determines the data values as it is a compilation of all the data values
Hence , the mean of the data describes the set

PLEASE ANSWER ASAP. What is the diagonal length of a photo frame with dimensions that are 24 cm x 7 cm?
A. 19 cm
B. 25 cm
C. 28 cm
D. 32 cm
Answers
Answer:
B
Step-by-step explanation:
The diagonal will become the hypotenuse of a right triangle, with the legs being 24 and 7.
Since it is a right triangle, we can use Pythagorean theorem
a^2+b^2=c^2
We know the legs: a and b, are 24 and 7, so we can substitute them in
24^2+7^2=c^2
Solve the exponents
576+49=c^2
Add
625=c^2
Take the square root of both sides
[tex]\sqrt{625}[/tex]=[tex]\sqrt{c^{2} }[/tex]
c=25
So, the diagonal will be 25 cm, or choice B

Lower bound =
Upper bound
Answers
Final answer:
The lower bound of the number rounded to 2 decimal places is 45.54, and the upper bound is 45.56.
Explanation:
To find the lower and upper bounds of a number when it is rounded to 2 decimal places, we need to consider the two possible values that round down and round up from the given number.
In this case, the number is 45.55.
The lower bound is the number rounded down.
When we round down 45.55 to 2 decimal places, we get 45.54.
The upper bound is the number rounded up.
When we round up 45.55 to 2 decimal places, we get 45.56.

Q = 180 - 135

With reference angle 60°
perpendicular (p) = 2√3
hypotenuse (h) = ?
We know
sin 60° = p/h
√3/2 = 2√3 / h
cross multiply
h =( 2√3 * 2)/ √3
therefore h = 4
So
Now
with reference angle 45°
perpendicular (p) = x
base (b) = 4

The graphed line shown below is y = negative 2 x minus 8.
On a coordinate plane, a line goes through (negative 4, 0) and (negative 2, negative 4).
Which equation, when graphed with the given equation, will form a system that has infinitely many solutions? y = negative 2 x minus 8.
y = negative (2 x + 8)
y = negative 2 (x minus 8)
y = negative 2 (x minus 4)
y = negative (negative 2 x + 8)
Answers
Answer:
A
Step-by-step explanation:
Our given equation is: y = -2x - 8
In order to have an equation with infinitely many solutions, it needs to be the same as the given equation.
Look at the answer choices:
A) y = -(2x + 8) = -2x - 8
This is the exact same equation, which means that any solutions for the given will also be solutions for this one. That means there will be infinitely many solutions.
B) y = -2(x - 8) = -2x + 16
We can tell this is definitely not the same as the given, so eliminate.
C) y = -2(x - 4) = -2x + 8
Again, this has a +8 instead of -8, so it's not the same and wrong.
D) y = -(-2x + 8) = 2x - 8
Here, we have positive 2 as the slope instead of -2, so it's not the same and wrong.
Thus, the answer is A.
Hope this helps!

Answers
To solve the quadratic equation x^2 + 9x + 18 = 0, you'll have to find values of x that satisfy this equation.
To find the roots of the quadratic equation, we use the formula x = [-b±sqrt(b^2 -4ac)]/2a, where a, b, c are the coefficients of the quadratic equation of the form: ax^2 + bx + c = 0.
In our equation, we have:
a = 1 (coefficient of x^2)
b = 9 (coefficient of x)
c = 18 (constant term)
Substituting these values in our formula, we get:
x = [-9±sqrt((9)^2 - 4*1*18)] / 2*1,
x = [-9±sqrt(81 - 72)] / 2,
x = [-9±sqrt(9)] / 2,
x = [-9±3] / 2.
From here, we get two solutions:
For the smaller solution, we have: x = [-9 - 3] / 2 = -6.
For the larger solution, we have: x = [-9 + 3] / 2 = -3.
So, the solutions to the equation x^2 + 9x + 18 = 0 are x = -6 (for the smaller solution), and x = -3 (for the larger solution).

The bathysphere was an early version of a submarine, invented in the 1930s. The inside
diameter of the bathysphere was 56 inches, and the steel used to make the sphere was 1.5
inches thick. It had three 10-inch diameter windows. Estimate the volume of steel used to
make the bathysphere to the nearest whole number.
It took about
in.of steel to make the bathysphere.
Answers
The volume of steel used to make the bathysphere is approximately 53,481 cubic inches.
Explanation:To estimate the volume of steel used to make the bathysphere, we need to calculate the volume of the sphere and subtract the volume of the windows. The volume of the sphere can be calculated using the formula for the volume of a sphere: V = (4/3)πr³, where r is the radius of the sphere. Since the diameter of the bathysphere is 56 inches, the radius is half of that, which is 28 inches. Converting to meters, the radius is approximately 0.7112 meters.
Now we can calculate the volume of the sphere: V = (4/3)π(0.7112)³ ≈ 0.8827 cubic meters.
The volume of each window can be calculated using the formula for the volume of a cylinder: V = πr²h, where r is the radius of the window and h is the height of the window. The radius of each window is half of the diameter, which is 5 inches or approximately 0.127 meters. The height of each window is 1.5 inches or approximately 0.0381 meters.
Now we can calculate the volume of each window: V = π(0.127)²(0.0381) ≈ 0.0024 cubic meters.
Since there are three windows, the total volume of the windows is 3 × 0.0024 ≈ 0.0073 cubic meters.
To estimate the volume of steel used to make the bathysphere, we subtract the volume of the windows from the volume of the sphere: approximately 0.8827 - 0.0073 ≈ 0.8754 cubic meters.
Finally, we convert the volume to cubic inches to estimate the amount of steel used: 0.8754 × 61023.7 ≈ 53481 cubic inches. Rounding to the nearest whole number, the volume of steel used to make the bathysphere is approximately 53,481 cubic inches.
