Find the area of the rectangle
Answer:
Option A = 1*3 = 3 unit²[tex]area \: of \: rectangle \: = length \: \times breath[/tex]
[tex]length \: = distance \: between \: f \: and \: g \: or \: between \: e \: and \: h \: [/tex]
Distance between f and G = distance between E and HF = (3,7)
G = (6,4)
H = (5,3)
E= (2,6)
= (3 units)
Distance between FE = GH= 1 units
Area = 3* 1
= 3 units²
Sometimes, a data set has two values that have the highest and equal frequencies. In this case, the distribution of the data can best be described as
A data set having two values that have the highest and equal frequencies will have a bimodal distribution. Hence, option D is the right choice.
A symmetric distribution occurs when the mean, median, and mode all occur at the same location and the values of the variables occur at regular intervals.The few low scores in a negatively skewed distribution tend to push the mean to the left, thus the mean is typically lower than the median.The mode is consistently less than the mean and median in a positively skewed distribution.A continuous probability distribution having two distinct modes, that is, two separate values with the highest and equal frequencies is referred to as a bimodal distribution.Thus, a data set having two values that have the highest and equal frequencies will have a bimodal distribution. Hence, option D is the right choice.

How do you find inverse functions?
will give brainliest to first helpful response
Answer:
swap x and y
Step-by-step explanation:
You can find an inverse function by replacing "x" and "y"
for example:
y = mx + b
becomes
x = my + b
if your equation is:
f(x) = 3(x²) - 3
{remember, f(x) means the same thing as y}
y = 3(x²) - 3
inverse:
x = 3(y²) - 3

A matrix is in row echelon form when the first non-zero number from the left i.e. leading coefficient is always to right of the first non-zero number in the row above and rows consisting of all zeros are at bottom of the matrix.
The row echelon form of the matrix is given in the question.
from row-echelon form of the matrix, we can write the equation as,
x-5z=-3
y-4z=-5
Let's assume z=t, where t is the real number

Are of quadrilateral
Answer:
Area of Quadrilateral = 289.57 sq.cm
Step-by-step explanation:
First of all, let us understand what is a Quadrilateral?
A quadrilateral is a polygon with four sides. A quadrilateral is a closed two-dimensional figure formed by joining the four points among which three points are non-collinear points.
Given,
Length of sides :
AB = 7.5 cm
BC = 11.7 cm
CD = 15.6 cm
AD = 18 cm
and given , the Angle between BCD is 90 degrees and the angle between BAD is 90 degrees.
It implies that the TRAINGLES BCD and BAD are Right angled triangles
So, the length of BD can be found using Pythagorean theorem
Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
From the Triangle of BCD,
a= BC
b=CD and
c= BD
Therefore, The length of BD =
c=[tex]\sqrt[2]{(11.7^{2})+(15.6 x^{2}) }[/tex]
c = [tex]\sqrt{380.25}[/tex]
c = 19.5 cm
Hence, c= BD=19.5 cm
Now, Area of Quadrilateral =
1/2*(diagonal)*(sum of height of two triangles)
Here, Diagonal = Length of BD = 19.5 cm
Height (h1) = BC = 11.7 cm
Height ( h2) = AD = 18 cm
Therefore, Area = 1/2*19.5*(11.7+18)
= 289.57 sq.cm

A cone has a volume of 24 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?
Answer: 72 cubic inches
Step-by-step explanation:
The formula for the volume of a cone: [tex]\dfrac{1}{3}\pi r^{2}h[/tex]
Formula for the volume of a cylinder: [tex]\pi r^{2}h[/tex]
We are given that a cylinder should fit exactly inside the cone
Upon comparing the two equations above, we get:
[tex]$$Volume of cone = \dfrac{1}{3}\text{Volume of cylinder}[/tex]
Since we are given the volume of cone is 24 cubic inches, we can write down the below:
[tex]24 = \dfrac{1}{3}\text{Volume of cylinder }\\ \text{Volume of cylinder = 72 cubic inches}[/tex]
Therefore, we can conclude that if the volume of the cylinder is 72 cubic inches, then the cone with volume of 24 cubic inches can fit exactly in.

Answer: B -4
Step-by-step explanation: I think it is B because -4 is smaller than A,C and D.
The smallest integer among the options provided is option A, which is -84.
In the context of integers, smaller values are considered to be "less" than larger values.
In this case, we can compare the given integers to determine the smallest one.
Comparing the options:
A. -84
B. -4
C. 34
D. 24
Out of these options, -84 is the smallest integer because it has the lowest numerical value.
The negative sign indicates that it is a number less than zero, and the absolute value of 84 is greater than the absolute values of -4, 34, and 24.
Therefore, based on numerical value, -84 is the smallest integer among the options given.

Carmela opened her piggy bank and found she had $15.30. If she had only nickels, dimes, quarters, and half-dollars and an equal number of coins of each kind, how many coins did she have in all
Answer:
68 coins
Step-by-step explanation:
We can use the given information to write two equations involving the numbers of coins. One will express the total number of coins; the other will express their value.
__
setupSince there are equal numbers of coins of each type, we can let n represent the number of each kind of coin. The total number coins will be ...
n +n +n +n + N . . . the sum of numbers of nickels, dimes, quarters, halves
The value of the coins is ...
0.05n +0.10n +0.25n +0.50n = 15.30
solutionThe second equation lets us find the value of n:
0.90n = 15.30
n = 17 . . . . . . . . divide by 0.90
Then the number of coins in all is ...
4n = N
4(17) = N = 68
Carmela had 68 coins in all.
A pair of jeans costs $58. They are on sale for 15% off. What is the discount and final price?
Discount = $ _._ _
Selling Price = $ _ _ . _ _
Answer:
Discount=$8.7
Selling price=$49.3
Step-by-step explanation:
First you need to write that in an equation form-
a/58=15/100
Then you need to do cross multiplication-
100a=58(15)
100a=870
Now divide 100 from both sides-
100a/100=870/100
a=8.7
Thats the discount rate
Now subtract that from the original price
58-8.7=49.3
Thats the price after the discount
