A researcher is working with two variables measured at the interval level. Which statistical tool should the researcher use
The researcher should use regression analysis, as a statistical tool, because the researcher is working with two variables measured.
Regression analysis
Regression analysis is the most widely used statistical tool that can be used to find out the relation between a set of variables. Thus, from its results, it is possible to analyze the trend or make predictions. In a regression analysis, it is considered the relationships between two or more variables and it is very similar to correlation.
Like the researcher is working with two variables measured at the interval level. The researcher should use regression analysis.

keeping in mind that a rhombus is also a parallelogram, namely a quadrilateral with parallel opposite sides, however, a rhombus sides are all the same length, and its diagonals meet at right-angles, Check the picture below.
The ratio of the required trigonometric function sin b₂° as per the given measurement of the quadrilateral is equal to 39/ 50.
Let us consider quadrilateral ABCD be rhombus.
Using the properties of the rhombus,
All the sides are congruent to each other.
Here, AB = 5 cm
This implies,
AB = BC = CD = AD = 5 cm
And Intersection of the diagonal is point 'O'.
In rhombus diagonals bisects each other at 90 degrees.
Measure of angle BOC = 90 degrees.
Triangle BOC is right angled triangle.
OC = 3.9 cm
sin b₂° = opposite side / hypotenuse
= OC / BC
= 3.9 / 5
= 0.78
= 78 / 100
= 39 / 50
Therefore, the ratio of the function sin b₂° is equal to 39 / 50.

. Mrs. Rojas deposited $8000 into an account paying 4% interest annually. After 8 months Mrs. Rojas withdrew the $6000 plus interest. Altogether, how much money did Mrs. Rojas withdraw? What fraction of a year's interest was earned? 760
well, keeping in mind that a year has 12 months, that means that 8 months is 8/12 of a year, when Mrs Rojas pull her money out.
[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$6000\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=years\to \frac{8}{12}\dotfill &\frac{2}{3} \end{cases} \\\\\\ A=6000[1+(0.04)(\frac{2}{3})]\implies A=6000\left( \frac{77}{75} \right)\implies A=6160[/tex]
well, she put in 6000 bucks, got back 160 extra, that's the interest earned in the 8 months.
what if she had left her money for 1 whole year, then
[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$6000\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=years\dotfill &1 \end{cases} \\\\\\ A=6000[1+(0.04)(1)]\implies A=6240[/tex]
so had she left it in for a year, she'd have gotten 6240, namely 240 in interest, well, what fraction of a year's interest was earned? or worded differently, what fraction is 160(8 months) of 240(1 year)?

Answer:
50 degrees
Step-by-step explanation:
If AB is congruent to BC, then angles BAC and BCA are congruent.
Angle DCB+ angle BCA= 180 degrees
180 degrees- 115 degrees= 65 degrees
It means that angles BCA and BAC (which are congruent) are equal 65 degrees.
Sum of angles i side a triangle is 180 degrees so:
180 degrees- 2*65 degrees= 180 degrees- 130 degrees= 50 degrees
The angle ABC is equal to 50 degrees.
if the population of a city is 158,000 and is
decreasing by 8% every year, what will the
population be in 5 years?
Answer:
~ 104 135
Step-by-step explanation:
Decreasing by 8% each year means 92% is left each year
Formula
FV = PV ( i)^n FV = population in future PV = pop now
i = 92% in decimal form = .92 n = years = 5
FV = 158000(.92)^5 = 104135
A percentage is a way to describe a part of a whole. The population of the city after 5 years will be 104135.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the population of a city is 158,000 and is decreasing by 8% every year. Therefore, the population of the city after 5 years will be,
Population after 5 years = 158,000(1-0.08)⁵
= 158,000 × 0.659
= 104134.8807 ≈ 104135
Hence, the population of the city after 5 years will be 104135.

What is the area of the composite figure?
Will mark brainlyest!!
Answer:
(a) 88 m²
Step-by-step explanation:
The area of a composite figure can be found by decomposing it into figures whose areas are easy to calculate. This figure can be decomposed any of several ways (as is often the case).
Drawing a vertical line down from the top-edge vertex, we can divide the figure into a trapezoid on the left and a rectangle on the right.
__
TrapezoidThe trapezoid will have (vertical) bases of 4 m and 6 m, and a height of (16-8) = 8 m. Its area is ...
A = 1/2(b1 +b2)h = 1/2(4 +6)(8) = 40 m²
RectangleThe rectangle on the right is 8 m wide and 6 m high, so its area is ...
A = LW = (8 m)(6 m) = 48 m²
TotalThe total area is ...
trapezoid area + rectangle area = 40 m² +48 m² = 88 m²
The area of the composite figure is 88 m².

A system of linear equations has one solution when the graphs intersect at a point. No solution. A system of linear equations has no solution when the graphs are parallel.
What’s the answer to this problem?
Answer:
Step-by-step explanation:
LA (Lateral area) = P (perimeter of the base) x h (distance between bases)
LA = 3 x 2
LA = 6
SA (surface area) = LA (Lateral area) + (2 x B (Area of the base))
SA = 6 + (2 x 0.25)
SA = 6.5m²
Answer:
7
Step-by-step explanation:
if you imagine the shape in your head, there would be 3 rectangles and 2 triangles.
so if you want the surface area of the entire shape, you have to add the areas of each of these sides
the area of 1 triangle is (1*1)/2 = 0.5
the area of 1 rectangle is more complicated:
you would have to work out the rectangles height, which is the hypotenuse of the triangle. so you use Pythagoras, and you get 1 (if you don't know how to do this search up Pythagoras theorem)
so now you can get the area of the rectangle: 1*2 = 2
3 rectangles : 2*3 = 6
2 triangles : 0.5 * 2 = 1
6+1 = 7

Which comparison is correct?
7 < |7|
-5 < -4
|5| > 7
|-5| < -4
Answer:
-5 < -4
|X| - this is read as magnitude of X and it means take the positive of that number X.
meaning if the number X is negative you can ignore the negative and write the positive value of the number.
so now:
|7| = 7
|5| = 5
|-5| = 5
7 = |7| not 7 < |7|
-5 < -4 is correct since on the number line numbers to the left are lesser than numbers on the right and -5 is on the left of -4 on the number line
|5| < 7 since |5| is just 5 and 5 is less than 7
|-5| > -4 not -5 < -4 since |-5| is 5 and 5 is greater than -4
hence correct answer is the second one

What is the slope of the line that passes through the points (1,−7) and ( − 2 , − 7 )? Write your answer in simplest form.
By definition, the slope or gradient of a line describes its steepness, incline, or grade.
Slope (m) = ΔY/ΔX= 0
ΔX = 2 – 1 = 1
ΔY = -7 – -7 = 0
