Giant spider crabs prefer an elevation of around -800 feet, and Atlantic wolffish prefer an elevation of around -300 feet.
tend to be farther from the surface of the ocean than .
Answer:
Elevation of the giant spider = -800 feetThat means depth of a giant spider below the surface of ocean = 800 feetElevation of the Atlantic wolfish = -300 feetIt shows depth of the Atlantic wolfish below the surface of the ocean = 300 feetNegative notation shows the distances below the surface of the ocean.Therefore, (Giant spider crab) tend to be farther from the surface of the ocean than (Atlantic wolfish.)

A bag contains 7 red marbles, 8 blue marbles and 4 green marbles. If three marbles
are drawn out of the bag, what is the probability, to the nearest 100oth, that all three
marbles drawn will be blue?
Answer:
Step-by-step explanation:
A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.
Total = 18 marbles.
Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.
Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.

You may already know, for example from the number of cubic inches in a cubic foot, that 12^3 = 1728. This power of 12 can be used to shorten the computation of the 12th power of 12 using the rules of exponents. The long multiplication working at each stage is shown in the attachments. Please note that the final denominator here has 13 digits, which most calculators will not show. A spreadsheet may be able to give you the full precision.
If you need a decimal fraction, not the one shown, then you can compute 1/0.2972...×10^-13 ≈ 3.3646...×10^-13 as shown in the 4th attachment. You should use at least as many digits in the divisor as you need significant digits in the quotient.
This is tedious to do by hand, but is not out of the question. Is there some reason a calculator cannot be used?

The number of favorable outcomes is 11 The probability of getting one of those outcomes is 11/36 . So the fraction you want is 11/36
C. In 100 throws, the outcome should be about 11/36 * 100 or about 31. That is too close to call. I'm going to try it with a million times and see what happens.
If I run this question a million times, I get 0.305 something. 100 is too small a sample to tell. I would expect it to be less than 34 times. If you run the simulation a million times, you get an answer that is very accurate to 3 places.
Even with a hundred times, you are going to get 34 or more very infrequently.

Answer:
x = 0.19 or x = -0.76
Step-by-step explanation:
Equation: 7²-4x = 2
reordering the equation,
7x²-4x-2 = 0
Applying,
x = [-b±√(b²-4ac)]/2a..................... Equation 1
From the question,
Given: a = 7, b = -4, c = -2
Substitute these values into equation 1
x = [-4±√(-4²-(2×7×-2)]/(2×7)
x = [-4±√(16+28)]/14
x = (-4±√44)/14
Either
x = (-4+√44)/14
x = (-4+6.63)/14
x = 2.63/14
x = 0.19
or
x = (-4-√44)/14
x = (-4-6.63)/14
x = -10.63/14
x = -0.76

These tables represent a quadratic function with a vertex at (0,-1) what is the average rate of change for the interval from x=7 to x=8?
B.-15
Step-by-step explanation:
The average rate of change from 7 to 8 = -15
How to determine the average rate of change?The average rate of change of a quadratic function is calculated using:
Rate = (f(b) - f(a))/(b - a)
The interval is from x = 7 to 8.
So, we have:
(a,b) = (7,8)
The equation becomes
Rate = (f(8) - f(7))/(8 - 7)
Evaluate the difference
Rate = (f(8) - f(7))/1
This gives
Rate = f(8) - f(7)
From the table, we have:
Rate from 5 to 6 = -11 where the constant is -2
So, we have:
Rate from 6 to 7 = -11 - 2
Rate from 6 to 7 = -13
Also, we have:
Rate from 7 to 8 = -13 -2
Rate from 7 to 8 = -15
Hence, the average rate of change from 7 to 8 = -15

An HP laser printer is advertised to print text documents at a speed of 18 ppm (pages per minute). The manufacturer tells you that the printing speed is actually a Normal random variable with a mean of 17.42 ppm and a standard deviation of 3.25 ppm. Suppose that you draw a random sample of 12 printers. Part i) Using the information about the distribution of the printing speeds given by the manufacturer, find the probability that the mean printing speed of the sample is greater than 18.12 ppm. (Please carry answers to at least six decimal places in intermediate steps. Give your final answer to the nearest three decimal places).
Answer:
0.227 = 22.7% probability that the mean printing speed of the sample is greater than 18.12 ppm.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 17.42 ppm and a standard deviation of 3.25 ppm.
This means that [tex]\mu = 17.42, \sigma = 3.25[/tex]
Sample of 12:
This means that [tex]n = 12, s = \frac{3.25}{\sqrt{12}}[/tex]
Find the probability that the mean printing speed of the sample is greater than 18.12 ppm.
This is 1 subtracted by the p-value of Z when X = 18.12.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{18.12 - 17.42}{\frac{3.25}{\sqrt{12}}}[/tex]
[tex]Z = 0.75[/tex]
[tex]Z = 0.75[/tex] has a pvalue of 0.773.
1 - 0.773 = 0.227
0.227 = 22.7% probability that the mean printing speed of the sample is greater than 18.12 ppm.

Answer:
x = 60, y = 110
Step-by-step explanation:
the interior angles of a triangle will always add up to 180.
take the angles we already have and add them, once you get your answer you have to subtract that by 180 to find the missing angle.
70 + 50 = 120
180 - 120 = 60
———————-
the line at the bottom is called a straight angle, and it’s measure is 180
the exterior angle is equal to the sum of the two opposite interior angles (50 and 60)
y = a + b
y = 50 + 60
110 = 50 + 60

Answer:
2.983
I hope it is helpful to you
The area of the region in the first quadrant bounded on the left and right by the two given graphs is; A: 2.983
What is the area bounded by the graph?
We are given the equations;
x = y⁴ + y² ----(eq 1)
x = 5y ----(eq 2)
Now, let us put eq 1 into eq 2 to get;
y⁴ + y² = 5y
y⁴ + y² - 5y = 0
Using online roots of polynomial calculator, we have;
y = 0 and 1.516
Thus, the area of the region will be gotten by finding the integral between those two points;
[tex]\int\limits^0_\frac{1.516}{} {y^{4} + y^{2} - 5y} \, dy[/tex]
Integrating this, we have;
[tex]\left[\begin{array}{ccc}y^{4} +y^{2} - 5y\\\\\end{array}\right]^{0}_{1.516}[/tex]
Plugging in the relevant values and subtracting gives;
