submarine titan descended 93 meters into the ocean to look for fish. Submarine Odyssey descended 3 times as deep. What is Odyssey's depth below sea level in meters?
Answers
Answer:
279 meters
Step-by-step explanation:
This is just some simple multiplication. 93*3=279
Submarine Odyssey's depth below sea level is 279 meters.
Given that two submarines titan and odyssey, titan descended 93 meters and odyssey descended 3 times as deep.
We need to find the depth of the submarine odyssey.
To find Odyssey's depth below sea level, we can start by determining the depth that Submarine Titan descended.
According to the given information, Submarine Titan descended 93 meters into the ocean to look for fish.
Now, we need to find the depth that Submarine Odyssey descended, which is three times as deep as Submarine Titan.
We can calculate this by multiplying the depth of Submarine Titan (93 meters) by 3:
Depth of Submarine Odyssey = 93 meters x 3 = 279 meters
Therefore, Submarine Odyssey's depth below sea level is 279 meters.

45.625cm²
Step-by-step explanation:
To solve this, we need to do the area of the circle - the area of the rectangle:
Area of the circle
a = πr² (r is the radius, half the diameter)
a = π × 4²
a = π × 16
a = 16π or 50.265cm²
Area of the rectangle
a = length × width
a = 5 × 1
a = 5cm²
50.265 - 5 = 45.265

Line m passes through
points X and Y. Line n passes through points x
and Z. If m and n have equal slope, what can
you conclude about points X, Y, and Z? Explain.
Answers
Answer:
X, Y, Z are collinear
Step-by-step explanation:
X,Y,Z lie on the same straight line
The slope of the lines are the same thus line m and n both passes through X, Y, and Z points and thus all three points will be colinear.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
Given that line m is passing →
Points X and Y
Line n passing →
Points X, Z
The slope of m = slope of n
If the slope same then the line will be parallel and since both lines are passing through the same point X thus they will be a colinear line.
All points that lie on the colinear line are colinear points.
Hence "X, Y, and Z all three points will be colinear".

Write an
exponential function in the form y = ab^x
that goes through points (0,13) and (3,832).
Answers
Answer:
y = 13 × [tex]4^{x}[/tex]
Step-by-step explanation:
Substitute the given values into the exponential
Using (0, 13 ) , then
13 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ) , so
a = 13
y = 13 [tex]b^{x}[/tex]
Using (3, 832 )
832 = 13 b³ ( divide both sides by 13 )
64 = b³ ( take cube root of both sides )
b = [tex]\sqrt[3]{64}[/tex] = 4
The exponential function is

Segment bisector of XY = line nLength of XY = 6Recall:
A line that divides a segment into two equal parts is referred to as segment bisector.In the diagram attached below, line n divides XY into XM and MY.
Thus, the segment bisector of XY is: line n.
Find the value of x:
XM = MY (congruent segments)
Substitute[tex]5x + 8 = 9x + 12[/tex]
Collect like terms and solve for x[tex]5x + 8 = 9x + 12\\5x - 9x = -8 + 12\\\\-4x = 4\\\\x = -1[/tex]

A recent report found that a local creamery has a 35% market share in a certain region. Employees in the marketing
department of the creamery conduct a survey to confirm the results by randomly selecting 300 residents from the regon
The employees asked the question which brand of ice cream do you usually purchase to each resident Use a normal
approximation to calculate the probability that at most 80 of these people will choose the creamery's brand. Use a T1-83,
83 plus, or T-34 calculator to find the probability
- Round your answer to four decimal places
Answers
Using the normal approximation to the binomial, it is found that there is a 0.0015 = 0.15% probability that at most 80 of these people will choose the creamery's brand.
In a normal distribution 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]
It 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, which is the percentile of X.The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with [tex]\mu = np, \sigma = \sqrt{np(1-p)}[/tex].In this problem:
35% market share, hence [tex]p = 0.35[/tex].300 residents are surveyed, hence [tex]n = 300[/tex].The mean and the standard deviation are given by:
[tex]\mu = np = 300(0.35) = 105[/tex]
[tex]\sigma = \sqrt{np(1-p)} = \sqrt{300(0.35)(0.65)} = 8.26[/tex]
Using continuity correction, the probability that at most 80 of these people will choose the creamery's brand is [tex]P(X \leq 80 + 0.5) = P(X \leq 80.5)[/tex], which is the p-value of Z when X = 80.5, thus:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{80.5 - 105}{8.26}[/tex]
[tex]Z = -2.97[/tex]
[tex]Z = -2.97[/tex] has a p-value of 0.0015.
0.0015 = 0.15% probability that at most 80 of these people will choose the creamery's brand.
