Determine the number of solutions for the equation shown below.
X = X-9
A. 1
B. 2
C. 0
D. Infinitely many
Answer:
The equation has 0 solutions (answer C).
Step-by-step explanation:
Starting with x = x - 9, we subtract x from both sides. This leaves us with:
0 = -9,
which is never true.
The equation has 0 solutions (answer C).
Roman runs 3 miles every morning. His mean time is 24.7 minutes and his standard deviation is 3.2 minutes. Which of the times is the least likely for Ramon to get?
Answer:
His time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.
Step-by-step explanation:
With an standard deviation of 3.2 minutes, it is clear that the maximum time taken by Roman to complete his run of 3 miles would be
Average time + standard deviation = 24.7 minutes + 3.2 minutes = 27.9 minutes
The minimum time taken by Roman to complete his run of 3 miles would be
Average time - standard deviation = 24.7 minutes - 3.2 minutes = 21.5 minutes
Hence, his time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.

In a triangle HIJ, i = 6.6 inches, j = 6.4 inches and Angle,H=62º. Find the length of h, to the
nearest 10th of an inch.
Answer:
7.6 inches
Step-by-step explanation:
We solve the above question using the Law of Cosines.
The formula is given as:
h² = i² + j² - 2ij Cos H
h = √i² + j² - 2ij Cos H
From the above question:
i = 6.6 inches
j = 6.4 inches
Length h = ?
Angle H=62º.
Hence:
h= √6.6² + 6.4² - 2 × 6.6 × 64 × Cos 62
h = √43.56 + 40.96 - 84.48 × Cos 62
h = 7.64292 inches
Approximately to the nearest tenth, Length h = 7.6 inches
Answer:
6.7

Find the midpoint of the segment with endpoints of 6+3i and -12-5i.
Remark
All you need do is add the two points together and divide by 2.
Group the like terms.
Answer: Midpoint = -3 - i
Answer:
-7 + 1i
Step-by-step explanation:
1. Find the midpoint of the segment with endpoints of 6 + 3i and −12 − 5i. -3 + -1i
2. Find the midpoint of the segment with endpoints of −11 + i and −4 + 4i.
-7.5 + 2.5i
3. A segment in the complex plane has a midpoint at −1 + 7i. If one endpoint of the segment is at
3 + 8i, what is the other endpoint?
-5 + 6i
4. A segment in the complex plane has a midpoint at −1.5 + 3.5i. If one endpoint of the segment is at 4 + 6i, what is the other endpoint?

A jar of M&M’s : 24 brown , 13 orange, 15 red , 10 green , 15 yellow , and 10 blue. Jim is blindfolded and will draw a single M&M out of the jar, What is the probability that it will be a brown one ?
Answer: 24/87 or 8/29
Step-by-step explanation:
24+13+15+10+15+10=87, the total amount of M&M's.
24 are brown, so 24/87 chance that he will draw a brown one.
24/87 = 8/29 simplified.

find the height x of the tree
Answer:
19.8 m
Step-by-step explanation:
To find the height of the tree, we can use the trig ratio tangent:
θ = angle, h = height
tan θ [tex]= \frac{opposite}{adjacent}[/tex]
tan 33° = h / 30.5
h = (tan 33°)(30.5)
h = (0.6494)(30.5)

There is a relationship between the total cost of renting a costume and the number of hours the costume is rented.
For 2 hours, the total cost is $50
For 5 hours, the total cost is $80
What type of variation is this relationship [ Direct or Partial] and what is the initial value?
Answer:
this means that for just an hour or 2 you're going to pay $25/hour which would be the initial value...but if you keep it for 5 hours you only pay $16/hour...the more you buy the less you pay per thing you're buying. ...this is a partial relationship, because there is an initial value greater than 0, and has a constant rate of change. a direct relationship would be when one variable did affects the other, meaning when one changes, so does the other ....it would mean the price got cheaper by a certain amount with every hour added ...in this example, the price doesn't get cheaper until hour 5, meaning the initial value is affected by the variable of hours rented...but is not a constant change, it is a partial change because it only changes under certain circumstances, (5 hours) rather than changing constantly with each passing hour....

If you roll a dice 600 times, on how many occasions would you expect to land on a 6
Answer:
100
Step-by-step explanation:
A dice has 6 sides and, theoretically, each side has the same probability of being rolled. So, if a dice was rolled a number of times, it would land on each side the same number of times. This means that 6 would be rolled 1/6 of the time. Since 1/6 of 600 is 100, that is how many times 6 would be rolled.

***11. Two angles form a linear pair. The measure of one angle is 24° more than the
measure of the other angle.
Answer:
The angles are 78° and 102°.
Step-by-step explanation:
Let the one angle is y and the other number if y + 24.
The sum of the angles of the linear pair is 180°.
So, according to the question
y + y + 24 = 180
2 y = 180 - 24
2 y = 156
y = 78°
So, one angle is 78° and the other is 78° + 24° = 102°.
For the function g(x)= -2/3x+5, determine x when g(x) = 25
Answer:
x = -30
Step-by-step explanation:
g(x)= -2/3x+5
Let g(x) = 25
25= -2/3x+5
Subtract 5 from each side
25-5= -2/3x+5-5
20 = -2/3x
Multiply each side by -3/2
-3/2 * 20 = -3/2 * -2/3 x
-30 = x
Answer:
x = -30
Step-by-step explanation:
g(x)= -2/3x+5
25 = -2/3x + 5
20 = -2/3x
x = -30

Which is the correct slope-intercept equation for a line that passes through the points (1,-3) and (-3,17)
Answer:
[tex]y=-5x+2[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0)1) Determine the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that the line passes through are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (1,-3) and (-3,17)
[tex]=\frac{17-(-3)}{-3-1}\\=\frac{17+3}{-3-1}\\=\frac{20}{-4}\\=-5[/tex]
Therefore the slope of the line is -5. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-5x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=-5x+b[/tex]
Plug in one of the given points and solve for b
[tex]-3=-5(1)+b\\-3=-5+b[/tex]
Add 5 to both sides of the equation to isolate b
[tex]-3+5=-5+b+5\\2=b[/tex]
Therefore, the y-intercept of the equation is 2. Plug this back into [tex]y=-5x+b[/tex]:
[tex]y=-5x+2[/tex]

N which number does the digit 5 have a value that is ten times greater than the value of the digit 5 in the number 245,093?
Answer:
53,901
Step-by-step explanation:
Here is the complete question :
In which number does the digit 5 have a value that is ten times greater than the value of the digit 5 in the number 245,093?
43,567
45,248
53,901
562,011
In the number 245,093 :
3 = units
9 = tens
0 = hundred
5 = thousand
4 = ten thousand
2 = hundred thousand
the value of 5 in the number is 5000. the number that would have a value that it 10 times greater than 5 in 245,093 must occupy the value of ten thousand.
looking through the options, it is only in 53,901 that 5 occupies a value of ten thousand
