Answer:
A = plane
B = whale
C = sunken ship
Step-by-step explanation:
The given vertical number line is modelling the positions of objects and animals in relation to sea level.
Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.
From inspection of the given number line:
Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.
We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Lateral surface of a triangular prism = Length × (a + b + c)
i hope it helps u :-)
Answer:
225 and 243.4
Step-by-step explanation:
Area of triangle = bh/2
A = 4*4.6/2
A = 9.2 cm sq
A of 2 triangles = 9.2*2 = 18.4 cm sq
Now, Area of 1 rectangle = lb --> 15*5 = 75 cm sq
A of 3 rectangles = 75*3 = 225 cm sq
Now, LSA = 225 cm sq. (excluding the triangles)
TSA = A of tr. + A of rec. = 18.4 + 225 = 243.4 cm sq

The length of ribbons found at a seamstress are listed. 3, 11, 11, 13, 13, 21 What is the appropriate measure of variability for the data shown, and what is its value? The mean is the best measure of variability and equals 11. The median is the best measure of variability and equals 11.5. The range is the best measure of variability and equals 18. The IQR is the best measure of variability and equals 2.
Answers
Answer:
(d) The IQR is the best measure of variability and equals 2.
Step-by-step explanation:
You want the best measure of variability of the data set {3, 11, 11, 13, 13, 21}.
VariabilityMean and median are measures of the center of the set of data, not its variability. The variability is measured by the range, interquartile range (IQR), or standard deviation.
Here, the range is the difference between the maximum and minimum values, 21 -3 = 18. The quartiles are 11 and 13, so the IQR is 13 -11 = 2.
OutliersThe minimum and maximum values are more than 1.5×IQR = 3 away from the upper and lower quartile values, so can be considered to be outliers. When we exclude the outliers from the data set, we have ...
{11, 11, 13, 13}
The best measure of the variability is the IQR, which is 2—corresponding to choice 4.

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

Step-by-step explanation:
You add 3/5 to -4/7 by finding the least common denominator (the bottom part of the fraction).
LCD is found by listing the multiples of the denominators and finding the common one.
5: 5, 10, 15, 20, 25, 30, 35
7: 7, 14, 21, 28, 35
For 3/5 you would multiply the numerator (the top part of the fraction) and denominator by 7, getting 21/35.
For -4/7, you would multiply the numerator and denominator by 5, getting -20/35.
21 + (-20) = 21 - 20 = 1
1/35
The final answer is that n is less than or equal to 1/35.
