PLEASE HELP! A) 2.9 B) 9.2 C) 3.3 D) 5
Answer:
9.2 =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp/ adj
tan 57 = x/6
6 tan 57 = x
9.239189783 = x
9.2 =x
The independent variable of interest in an ANOVA procedure is called a a. partition. b. factor. c. treatment. d. response.
Answer:
Option b (factor) is the correct choice.
Step-by-step explanation:
ANOVA would be used to assess whenever there were other statistically representative variations seen between results of two or even more individual (totally unconnected) categories.
Two different kinds of independent variables exist such as:
ActiveReferenceIf the explanatory variables are such an effective variable otherwise we modify the argument of the variable to test its effect on something like a specific parameter.
Certain solutions don't apply to the specified scenario. So choice B was its perfect method for that.

Answer:
the area is: 90 square inches
Step-by-step explanation:
Since you use the same amount of material to create the rectangle, that means that the area of a parallelogram has the same formula as the area of a rectangle. That is:
Area of parallelogram = base x height
In our case: 9 in x 10 in = 90 square inches
Which expression is equivalent to (73)5 • 74 ?
Select each correct answer.
Question 3 options:
73 • 5 + 4
73 + 5 + 4
73 + 5 • 74
73 • 5 • 74
The correct answer is D. 73 • 5 • 74
Explanation:
In mathematics, multiplication can be represented by using the symbol × or the symbol ·. Moreover, multiplication can be also represented just by leaving the numbers or values side by side without any symbol. For example, the expression 5x + y implies 5 should be multiplied by x. In this context, the expression (73)5 • 74 indicates 5 should be multiplied by 74, and the result of this should be multiplied by 73 as the lack of symbol indicates multiplication. Therefore, this is equivalent to 73 • 5 • 74.
Answer:
D
Step-by-step explanation:
Determine whether the following statement is true or false.
For a test of independence, the population that the data has come from must be normally distributed.
A. True
B. False
Answer:
The provided statement is False.
Step-by-step explanation:
The assumptions to perform a test of independence are:
The sample selected is randomA large sample is selectedThe observations are independent of each otherThe observations follow the same distribution.It is not necessary that the parent population or the population from which the sample is collected is normally distributed.
Thus, the provided statement is False.
In which situation is it best to use a line graph?
A): when the values on both axes are numbers
B): when a grade distribution is displayed
C): when showing trends
D): when representing parts of a whole
Answer: C): when showing trends
Step-by-step explanation:
A Line graph connects different points such that it appears as a line. For this reason it is very useful in showing the trend in the movement of values overtime.
When plotting line graphs the independent variable for example 'months' is usually put on the x-axis and a dependent variable such as 'temperature' will be on the y-axis.
When plotted, the line will be able to show just how things have changed overtime such that the change is quite easy to see through the movement of the line.

Answer:

AB = 14 units
Step-by-step explanation:
From the picture attached,
In the given triangles ΔAEB and ΔCDB,
AE║CD and ED is a transverse,
∠EAB ≅ ∠DCB [Alternate interior angles]
AE║CD and AC is a transverse,
∠AEB ≅ ∠CDB [Alternate interior angles]
ΔAEB ~ ΔCDB by AA property of the similarity of two triangles.
Therefore, corresponding sides of these triangles will be proportional.
[tex]\frac{\text{AE}}{\text{CD}}=\frac{\text{BE}}{\text{BD}}=\frac{\text{AB}}{\text{BC}}[/tex]
[tex]\frac{\text{BE}}{\text{BD}}=\frac{\text{AB}}{\text{BC}}[/tex]
⇒ [tex]\frac{7}{4}=\frac{2x+4}{x+3}[/tex]
⇒ 7x + 21 = 8x + 16
⇒ 8x - 7x = 21 - 16
⇒ x = 5
AB = (2x + 4)
= 10 + 4
= 14 units
mr udoh invested an amount in two separate finance firms in the ratio 3:5
his profit was calculated in 8% and 10% respectively . after a year he recieved a profit an interest of 92000. caculate the total amount invested
Answer:
$994,594.59
Step-by-step explanation:
If the investments were in the ratio 3:5, the returns on those investments were ...
3×0.08 +5×0.10 = 0.74 . . . . . ratio units
This return is $92,000, so each ratio unit of investment is ...
$92,000/0.74 = $124,324.32 (and change)
The total investment was 8 ratio units, so was ...
$124,324.32 × 8 = $994,594.59 . . . . total amount invested.
_____
Check
3/8 of the invested amount earned 8%, so that interest was ...
$994,594.59×(3/8)×(0.08) = $29,837.84
5/8 of the invested amount earned 10%, so that interest was ...
$994,594.59×(5/8)×(0.10) = $62,162.16
The total interest earned was $29,837.84 +62,162.16 = $92,000.

On a number line, A is at -2 and B is at 4. What is the coordinate of C, which is 2/3
the way from A to B?
Answer:
2
Step-by-step explanation:
The distances have the ratio:
(C -A) = (2/3)(B -A)
C = (2/3)B +(1/3)A . . . . . add A
C = (2B +A)/3 . . . . . . . . combine terms
C = (2(4) +(-2))/3 = 6/3 = 2
The coordinate of C is 2.

what is the Transformation of a function?
Answer:A function transformation takes whatever is the basic function f (x) and then "transforms" it (or "translates" it), which is a fancy way of saying that you change the formula a bit and thereby move the graph around. Moving the function down works the same way; f (x) – b is f (x) moved down b units.

Answer:
[tex]\large \boxed{\mathrm{served \ a \ greater \ variety \ of \ ages}} \\ \\ \large \boxed{\mathrm{range}}[/tex]
Step-by-step explanation:
Restaurant A served a greater variety of ages than Restaurant B, because the range of data for Restaurant A is greater than that of Restaurant B.
Range of a data set is the data spread.
Restaurant A is serving a greater variety of ages of people since it has a higher range than that of Restaurant B.
Answer:
1. Served a greater variety of age
2. range
Step-by-step explanation:
Restaurant A served a greater variety of age than Restaurant B, because the range of data for Restaurant A is greater than that of Restaurant B.
=> When we see the box plot, we come to know that the range (maximum - minimum) is greater for Restaurant A.

15 ‒ 5x = 6x + 3 – 2x
Answer:
x = 4/3
Step-by-step explanation:
15 - 5x = 6x + 3 - 2x
In this kind of equation, we try to seperate the x's and the numbers.
So we add 5x to both sides and subtract 3 from both sides to seperate these values
15 - 3 - 5x + 5x = 6x + 3 - 3 - 2x + 5x
=> 12 = 9x
=> 12/9 = x
=> 4/3 = x
=> x = 4/3
To check, we can plug this in.
15 - 5(4/3) = 6(4/3) + 3 - 2(4/3)
15 - 20/3 = 24/3 + 3 - 8/3
45/3 - 20/3 = 24/3 + 9/3 - 8/3
25/3 = 25/3
So our answer works.

The completion times for a job task range from 10.1 minutes to 19.2 minutes and are thought to be uniformly distributed. What is the probability that it will require between 12.7 and 16.8 minutes to perform the task
Answer:
The probability is [tex]P(12.7 < x < 16.8 ) = 0.45[/tex]
Step-by-step explanation:
From the question we are told that
The completion times for a job task range from 10.1 minutes to 19.2 minutes
Generally given that the completion times is uniformly distributed then the probability that it will require between 12.7 and 16.8 minutes is mathematically represented as
[tex]P(12.7 < x < 16.8 ) = \frac{ 16.8 - 12.7}{ 19.2 - 10.1 }[/tex]
[tex]P(12.7 < x < 16.8 ) = 0.45[/tex]
