The ratio of the weight of an object on Planet A to the weight of the same object on Planet B is 100 to 3. If an elephant weighs 3200 pounds on Planet A, find the
elephant's weight on Planet B.
The elephant's weight on Planet B is….. lb.

A ratio shows us the number of times a number contains another number. The elephant's weight on Planet B is 96 pounds.
What is a Ratio?A ratio shows us the number of times a number contains another number.
The ratio of the weight of an object on Planet A to the weight of the same object on Planet B is 100 to 3.
Weight on Planet A/ Weight on planet B = 100 / 3
Now, the weight of the elephant on planet A to Planet B will be,
elephant's weight on Planet A/elephant's weight on Planet B = 100 / 3
elephant's weight on Planet B = (3 ×3200)/100
elephant's weight on Planet B = 96 pounds
Hence, the elephant's weight on Planet B is 96 pounds.

Answer:
B.) The graph of m(x) is wider.
Both graphs open upward.
Both have the axis of symmetry x = 0.
The vertex of m(x) is (0, 4); the vertex of n(x) is (0, 0).
Step-by-step explanation:
When the coefficient before x² is greater than 1, the curve of the graph is narrower. When the coefficient is less than 1, the curve of the graph is wider.
When the coefficient in front of x² is positive, the graph opens upwards. When the coefficient is negative, the graph opens downwards.
The axis of symmetry is the "x" value which divides the curve into two equal sections. Their axis of symmetry are both x = 0 because their vertexes (the lowest point of the curve) are both at x = 0.
The vertex can be found by plugging x = 0 into both of the equations and then solving. The resulting value is the "y" position of the vertex.
m(0) = 0.7(0)² + 4 n(0) = (0)²
m(0) = 0 + 4 n(0) = 0
m(0) = 4
Therefore, the vertexes are m(x) = (0,4) and n(x) = (0,0).

The data is skewed.
What are the true statements?A box plot is used to study the distribution and level of a set of scores
The end of the first whisker represents the minimum number and the end of the second whisker represents the maximum number.
On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile. The interquartile range is the difference between the first and third quartile.
Interquartile range = 9 - (-1) = 10
A box plot is negative skewed because the median is not at the center of the box.
An outlier would be within: (Q1 - 1.5 * IQR or Q3 + 1.5 * IQR).

Given the right triangle shown, solve for X, Y and Z. The triangle may not be drawn to scale
Answers
Answer:
X ≈ 8.58 ftY ≈ 9.46 ftZ = 65°Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to help you remember the relationships between sides of a right triangle and trig functions of the acute angles. It tells you ...
Sin = Opposite/HypotenuseCos = Adjacent/HypotenuseTan = Opposite/AdjacentSidesThe given triangle shows values of an acute angle and its opposite side. You are to find the other two sides in the triangle, as well as the other acute angle.
X is the side adjacent to the given angle, so the relevant trig relation is ...
Tan = Opposite/Adjacent
tan(25°) = (4 ft)/X
Solving for X gives ...
X = (4 ft)/tan(25°) . . . . . . . . multiply by X/tan(25°)
X ≈ 8.58 ft
Y is the hypotenuse, so the relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(25°) = (4 ft)/Y
Y = (4 ft)/sin(25°) . . . . . . multiply by Y/sin(25°)
Y ≈ 9.46 ft
AngleThe sum of angles in a triangle is 180°, so if one of them is 90°, the sum of the other two is 90°.
Z = 90° -25°
Z = 65°

a) The point (2, -7/5) is not a point on the graph?
b) The value of f(x) when x is 1 is -1/3 and the point on the graph is (1, -1/3)
c) The value of x for f(x) = 2 is 22 and the point on the graph is (22, 2)
d) The domain of x is all real values of x ≠ 10
e) The x intercept is -2
f) The y intercept is -1/5
What is a Function?Function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output and not one input for two outputs.
Analysis:
a) To test if the point (2, -7/5) is a point on the graph, we put in x = 2 into the function,
f(2) = 2+2/2-10 = 4/-8 = -1/2 ≠ -7/5. Therefore (2, -7/5) is not a point on the graph.
b) if x = 1, f(1) = 1 +2 / 1-10 = 3/-9 = - 1/3
The point on the graph is (1, -1/3)
c) if f(x) = 2, then 2 = x+2/x-10
2(x-10) = x+2
2x -20 = x+2
2x-x = 2+20
x = 22, the point on the graph is (22, 2)
d) The domain of the function is such that the denominator would not be zero.
so if x - 10 ≠ 0
Then the values of x ≠ 10 are the domain of the function.
e) The x intercept of the graph is the point at which f(x) = 0
0 = x+2/x-10
x+2 = 0
x = -2. The x-intercept is -2.
f) the y-intercept is such that x = 0
0+2/0-10 = 2/-10 = -1/5
