What is the area of this figure?
Answers
Answer:
90km² only if it is parallelogram
Step-by-step explanation:
base = 9km
height=10km
area of parallelogram = b x h
=9km x 10km
=90km²
Answer:
A = 90km2
Step-by-step explanation:
Area of a rhombus is:
1. A = s x h (if given side and height)
2. A = 1/2 a x b (if given lengths of diagonals)
3. A = s^2 sin A (if given side and length)
Therefore from your problem, height and side is given thus, you'll use number 1
A = s x h
A = 9km x 10km = 90km2
PLEASE HELP W THIS I WILL Give YOU THE BRAINLIEST PLEASE ! - What does it mean to have a skewed distribution? What causes a skew in statistical terms? And how does one deal with skewed data when conducting research? Are there specific types of
research questions and types of data where one would expect the data to be skewed?
Answers
Answer:
Explained below
Step-by-step explanation:
A) A skewed distribution in a dataset is when the median is not equal to the mean in such a manner that the bell curve is tilted to the left or right.
B) If in a data set, if there are outliers which are extremely large or extremely small in comparison to other values in that same dataset, then we can say that such a curve will be pulled towards the outlier and thus the distribution is skewed.
Also, if the curve is inclined to the left, it means there are few extreme values to the left and it is negatively skewed.
Similarly, if the curve is inclined to the right, it means there are few extreme values to the right and is positively skewed.
C) Example of a research question is;
If in a developed country where the poverty level is about 0%, if we collect the data of income of the households, we will discover majority of people with average income and very few people with extreme high levels of income. This condition means the data is positively skewed.
A sequence is defined by the recursive function f(n+1)=f(n)-2
If f(1)=10 what is f(3)?
Answers
Answer:
f(3) = 6
Step-by-step explanation:
Using the recursive rule and f(1) = 10 , then
f(2) = f(1) - 2 = 10 - 2 = 8
f(3) = f(2) - 2 = 8 - 2 = 6
Given :-
A sequence is defined by f(n + 1) = f(n) -2 .f(1) = 10To Find :-
The value of f(3) .Solution :-
As per Question ,
→ f(n + 1) = f(n) - 2
→ f(n + 1 ) - f(n ) = -2
Therefore , the second term of the sequence is ,
→ f(2) - f(1) = -2
→ f(2) - 10 = -2
→ f(2) = 10 -2
→ f(2) = 8
Similarly,
→ f(3) - f(2) = -2
→ f(3) = 8 -2
→ f(3) = 6
Hence the value of f(3) is 6 .A rectangle has its base on the x-axis and its upper two vertices on the parabola y = 49 − x2. What is the largest possible area (in squared units) of the rectangle?

The parabola is a 'mountain'-type (because the coefficient of

graph{49-x^2 [-65.4, 66.33, -13.54, 52.3]}
Let the base of the rectangle be of length 2x, so its vertices on the parabola are (−x, 49 − x²) and (x, 49 − x²).
The area A of the rectangle is given by A = 2x(49 − x²), which simplifies to A = 98x − 2x³.
What is Rectangle?A rectangle is a four-sided polygon with opposite sides being congruent and parallel to each other, and all interior angles measuring 90 degrees.
To find the maximum possible area, we need to find the value of x that maximizes A. To do this, we take the derivative of A with respect to x and set it equal to zero:
dA/dx = 98 - 6x² = 0
Solving for x, we get x = ±√(98/6) ≈ ±4.1
Since the rectangle is symmetric about the y-axis, we only need to consider positive values of x. Therefore, the length of the base of the rectangle is 2x ≈ 8.2.
The height of the rectangle is 49 − x² ≈ 47.9.
The maximum area of the rectangle is then A ≈ 392.18 square units.

Ivan is saving money to buy a game. So far he has saved 8, which is one-fourth of the total cost of the game. How much does the game cost?
Answers
Answer:
[tex]\$32[/tex]
Step-by-step explanation:
Let the cost of the game be [tex]x[/tex]. Since one-fourth of the cost of the game is equal to 8 dollars, we have the following equation:
[tex]\frac{1}{4}x=8[/tex]
Multiply both sides by 4 to isolate and solve for [tex]x[/tex]:
[tex]x=8\cdot 4=\boxed{\$32}[/tex]

[/tex]
Then, we can change the division into multiplication by changing 8/20 into it’s reciprocal, 20/8.
This gives us 16/5 * 20/8.
We can then simplify this to 2/1 * 4/1
You then multiply the two fractions to get 8/1 which is equivalent to 8.
Which of the coordinate points below will fall on a line where the constant of proportionality is 23? Select all that apply.
A) (6,8)

C) (6,4)
D) (9,6)
E) (12,8)
Answers
Answer:
(3,2)
(6,4)
(9,6)
(12,8)
Step-by-step explanation:
Constant of proportionality is 2/3
This means that:
[tex]y = \frac{2}{3}x[/tex]
Thus, y should be less than x, which removes option A.
B) (3,2)
x = 3, so:
[tex]y = \frac{2}{3}x = \frac{2}{3}3 = 2[/tex]
So (3,2) is on the line
C) (6,4)
x = 6, so:
[tex]y = \frac{2}{3}x = \frac{2}{3}6 = 4[/tex]
So (6,4) is on the line
D) (9,6)
x = 9, so:
[tex]y = \frac{2}{3}x = \frac{2}{3}9 = 6[/tex]
So (9,6) is on the line
E) (12,8)
x = 12, so:
[tex]y = \frac{2}{3}x = \frac{2}{3}12 = 8[/tex]
So (12,8) is on the line

If you were given a fractional strip, that did not have any subdivisions marked like this one pictured below, how would you determine the fractional amount of the bar that is shaded?
Answers
9514 1404 393
Answer:
it depends on the accuracy and resolution required of the answer
Step-by-step explanation:
The shaded portion appears to be about half the length of the unshaded portion, suggesting the shaded amount is 1/3.
__
Using a pair of dividers, one could determine the number of times the shaded portion fits into the whole bar. Depending on how much is left over, the process could repeat to determine the approximate size of the remaining fraction relative to the bar or to the shaded portion. (Alternatively, one could replicate the length of the bar to see what integer number of shaded lengths fit into what integer number of whole lengths.)
One could measure the shaded part and the whole bar with a ruler, then determine the relative size of the shaded part by dividing the first measurement by the second. The finer the divisions on the ruler, the better the approximation will be.
If f(x)=2x²-x find f(-3)

f(-3) = 2*(-3)^2 - (-3)

=21
Answer: 21
Step-by-step explanation: To find f(-3) or the value of the function when x = -3, we plug in a -3 for the x in our function and we have 2(-3)² - (-3).
Start by simplifying the exponent to get 9.
So we have 2(9) - (-3) or 18 + 3 which is 21.
