Which expression shows how to convert 60 hours to days?
A 60 hours 1 hour 1 24 days
B 60 hours 1 day Х 1 24 hours
C 60 hours 24 hours X 1 1 day
D 60 hours 24 days 1 1 hour X
Answer:
B. [tex] \frac{60 hours}{1} \times \frac{1 day}{24 hours} [/tex]
Step-by-step explanation:
Converting 60 hours to days:
24 hours = 1 day
60 hours = x day
Cross multiply
[tex] 24 hours \times x = 60 hours \times 1 day [/tex]
Divide both sides by 24 hours
[tex] x = \frac{60 hours \times 1 day}{24 hours} [/tex]
Thus,
[tex] \frac{60 hours \times 1 day}{24 hours} = \frac{60 hours}{1} \times \frac{1 day}{24 hours} [/tex]
The expression that shows how to convert 60 hours to days is:

Consider a population with 3 observations: 6, 10 and 12. You use simple random sampling without replacement to select a sample of 2 observations. What is the probability that the sample mean is larger than 8?
Answer:
[tex]\dfrac{2}{3}[/tex]
Step-by-step explanation:
Given that:
The number of observations is:
6, 10, 12
If we are to use a simple random sampling without replacement, then we will have:
(6,10) (6,12) (10,12)
Here;
the sample size n = 2
The population size N = 3
For (6,10) ; The sample mean = [tex]\dfrac{6+10}{2}[/tex]
= [tex]\dfrac{16}{2}[/tex]
= 8
For (6,12) ; The sample mean = [tex]\dfrac{6+12}{2}[/tex]
= [tex]\dfrac{18}{2}[/tex]
= 9
For (10, 12) ; The sample mean = [tex]\dfrac{10+12}{2}[/tex]
= [tex]\dfrac{22}{2}[/tex]
= 11
The probability distribution of sample mean(x) is:
X 8 9 11
P(X=x) [tex]\dfrac{1}{3}[/tex] [tex]\dfrac{1}{3}[/tex] [tex]\dfrac{1}{3}[/tex]
Thus, the probability that the sample mean is larger than 8 is:
P(X> 8) = P(X = 9) + P(X + 11)
P(X> 8) = [tex]\dfrac{1}{3}+\dfrac{1}{3}[/tex]
P(X > 8) = [tex]\dfrac{1+1}{3}[/tex]
P(X> 8) = [tex]\dfrac{2}{3}[/tex]

The simplified trigonometric expression is given as follows:
[tex]-sin{\theta}\tan{\theta}(1 - \csc{\theta})[/tex]
How to simplify the given trigonometric expression?The expression is given by:
[tex]\frac{\cos{\theta}}{1 + \csc{\theta}} \times \frac{1 - \csc{\theta}}{1 - \csc{\theta}}[/tex]
Applying the subtraction of perfect squares at the denominator, we have that the expression is given by:
[tex]\frac{\cos{\theta}(1 - \csc{\theta})}{1 - \csc^2{\theta}}[/tex]
Applying an identity, we have that:
[tex]1 - \csc^2{\theta} = -\cot^2{\theta}[/tex]
Hence the expression is:
[tex]-\frac{\cos{\theta}(1 - \csc{\theta})}{\cot^2{\theta}}[/tex]
cot = cos/sin, hence:
[tex]-\frac{sin^2{\theta}(1 - \csc{\theta})}{\cos{\theta}}[/tex]
tan = sin/cos, hence the simplified expression is:
[tex]-sin{\theta}\tan{\theta}(1 - \csc{\theta})[/tex]

What is the difference between the following two regression equations? Choose the correct answer below.
A. The first equation is for sample data; the second equation is for a population.
B. The first equation is for a population; the second equation is for sample data.
Answer:
The correct option is (A). The first equation is for sample data; the second equation is for a population.
Step-by-step explanation:
According to the scenario, the following would be represented as a sample and the population
Y with caret = b0 + b1x = sample
and
y = b0 + b1x = population
It is because if we considered the population than the expected value would be nearest and there is no need to determine the b0 and b1 value again. But in the case of the sample, the reestimation of the values would be determined again and again
Therefore the correct option is A.

Step-by-step explanation:
Required
Which is undefined at a = 1
An expression is undefined when its denonimator equals 0.
So, we have to test the denominator of each.
(A): 7a + 7
This gives:
[tex]= 7(1) + 7[/tex]
[tex]= 7 + 7[/tex]
[tex]= 14[/tex]
(B): 5a - 10
This gives:
[tex]= 5(1) - 10[/tex]
[tex]= 5- 10[/tex]
[tex]= -5[/tex]
(C) -a² + 1
This gives
[tex]-(1^2) + 1[/tex]
[tex]= -1 + 1[/tex]
[tex]=0[/tex]
(D) 3a²
This gives:
[tex]= 3(1)^2[/tex]
[tex]= 3 * 1[/tex]
[tex]= 3[/tex]
Notice that only (C) equals 0.
Hence:
[tex]\frac{10a + 6}{-a^2 + 1}[/tex] is undefined at a = 1

This portion of the graph is completely flat, and has a slope of 0. The slope is the rate of change. Any horizontal line has a slope of 0 (we can use the slope formula to prove this). The term 'constant" means "it does not change".
In contrast, sections A, B, and D are all increasing sections because they go uphill as we move from left to right. The slopes of each line segment are positive.

Find the value of x that makes each parallelogram the given type
The value of x that will make each of the parallelogram the given type is:
11. x = 6.5
12. x = 3
What are Some Examples of Parallelogram?A parallelogram is any quadrilateral whose opposite sides are parallel and equal to each other.
Examples of a parallelogram include:
RhombusSquareRectangle11. The diagonals of a square intersect at right angles, therefore:
13x + 5.5 = 90
13x = 90 - 5.5
13x = 84.5
x = 84.5/13
x = 6.5
12. The four sides of a rhombus are equal in length, therefore:
14 - x = 2x + 5
14 - 5 = 2x + x
9 = 3x

The mean of a set of 10 numbers is 22. Four of these
numbers (8, 12, 21, and 23) are removed from the set.
What is the mean of the six remaining numbers?
A. 19
B. 21
C. 26
D. 28
==========================================================
Explanation:
The mean of all ten numbers is 22.
This tells us the sum of those ten numbers is 10*22 = 220
Recall that
mean = (sum of items)/(number of items)
We take this process in reverse to find the sum.
In other words:
sum = (mean)*(number of items)
--------------
Now remove the elements {8,12,21,23} to get a new sum of:
220-8-12-21-23 = 156
Divide that smaller sum over 6 since removing 4 elements leaves us with 10-4 = 6 left over.
new mean = (new smaller sum)/(number of items)
new mean = (156)/(6)
new mean = 26

An items price is increased by $10 then decreased by $10. Is the decreas percent and the increase percent equal
The increased percent and decreased percent of an item are not equal.
What is Percent formula?
Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
Now,
Let the original price of an item = $100
After increased by $10,
Increased percent of an item = 10 * 10/100 = 10%
The new cost of an item = $100 + $10 = $110
After decreased by $10,
Decreased percent of an item = 10 * 10/110 = 9.1%

this i dont understand i dont understand what an interception is -
Answer: its 2
Step-by-step explanation: An intercept is where the line crosses over the x or y axes.
Trapezoid RSTV with vertices R(-1,1), S(4, 1), T(4, -1), and V(-1, -3) and is reflected across y = -3
The vertices of the image are R'(x, y) = (- 1, - 7), S'(x, y) = (4, - 7), T'(x, y) = (4, - 5) and V'(x, y) = (- 1, - 3).
What are the coordinates of the vertices of the image by using a reflection formula?
In this question we know the locations of the four vertices of the trapezoid RSTV and we need to determine the coordinates of its image by using a reflection formula about an axis parallel to the y-axis, whose formula is described below:
P'(x, y) = P(x, y) - 2 · [P(x, y) - (p, k)]
Where:
p - x-Coordinate of the original point.k - y-Coordinate of the reflection axis.P(x, y) - Original pointP'(x, y) - Resulting pointNow we proceed to find the coordinates of the images:
R'(x, y) = (- 1, 1) - 2 · [(- 1, 1) - (- 1, - 3)]
R'(x, y) = (- 1, 1) - 2 · (0, 4)
R'(x, y) = (- 1, 1) + (0, - 8)
R'(x, y) = (- 1, - 7)
S'(x, y) = (4, 1) - 2 · [(4, 1) - (4, - 3)]
S'(x, y) = (4, 1) - 2 · (0, 4)
S'(x, y) = (4, 1) + (0, - 8)
S'(x, y) = (4, - 7)
T'(x, y) = (4, - 1) - 2 · [(4, - 1) - (4, - 3)]
T'(x, y) = (4, - 1) - 2 · (0, 2)
T'(x, y) = (4, - 1) + (0, - 4)
T'(x, y) = (4, - 5)
V'(x, y) = (- 1, - 3) - 2 · [(- 1, - 3) - (- 1, - 3)]
V'(x, y) = (- 1, - 3) - 2 · (0, 0)
V'(x, y) = (- 1, - 3)
The vertices of the image are R'(x, y) = (- 1, - 7), S'(x, y) = (4, - 7), T'(x, y) = (4, - 5) and V'(x, y) = (- 1, - 3).
