An appliance store sells microwave ovens and has many different styles to choose from. A handout from the store
contains details about brand, type (countertop or over-range), number of power settings, and color. Which of the
variables is a discrete quantitative variable?
O brand
O type
power settings
O color
Answer:
Power settings.
Step-by-step explanation:
In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.
Basically, random variables are classified into two (2) main categories and these are; continuous and discrete random variable.
A discrete random variable is a data set in which the number of possible values are either finite or countable. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
In this scenario, an appliance store sells microwave ovens and has many different styles to choose from. A handout from the store contains details about brand, type (countertop or over-range), number of power settings, and color.
Hence, the variable which is a discrete quantitative variable is the number of power settings because its values are countable or finite, usually it ranges from 100 to 800.
If Ryan gives 4/9 of his 36 cards to Josiah, how many cards does he give Josiah?
Answer:
16 cards
Step-by-step explanation:
Answer:
Ryan gave 16 cards to Josiah.
Step-by-step explanation:
First we will divide 36 by 9.
36/9 = 4
We know that 1/9 of 36 is 4.
1/9 + 1/9 + 1/9 + 1/9 = ?
4 + 4 + 4+ 4 = ?
4 * 4 = 16
4/9= 16
Ryan gave 16 cards to Josiah.
The 7th grade class experienced a 15% decrease in enrollment.Last year,the 7th grade class had 280 students. How many how many students are enrolled in the 7th grade this year?
Answer: 238
Step-by-step explanation: 10% of 280 is 28. 1% of 280 is 2.8. Multiply 2.8 times 5 and you get 14. Add 10% and 5% (28+14) and you get 15% which is 42. Subtract 42 from 280 and you get 238.
Answer:
232 students are enrolled this year.
Step-by-step explanation:
Since 15% of the enrollment of the previous year is gone, you must take 15% of the total number of students and subtract that from the total number of students.
[tex]280*0.15=42[/tex]
This tells us that the 15% decrease means there are 42 fewer students enrolled this year. Now you would just subtract 42 from 280.
280 - 42 = 232

3 congruent angles
Geometry
Answer:
The correct options are;
3 Congruent sides
Corresponding congruent Angle-Side-Angle
Corresponding congruent Side-Angle-Side
Corresponding congruent Side-Side-Angle
Step-by-step explanation:
The conditions for congruency are;
Two triangles are congruent when
AAS which is the acronym for corresponding Angle-Angle-Side are congruent
SAS which is the acronym for corresponding Side-Angle-Side are congruent
SSS which is the acronym for corresponding Side-Side-Side are congruent
ASA which is the acronym for corresponding Angle-Side-Angle are congruent.
The criteria that always proves triangles
are congruent are;
Option A; Corresponding congruent Angle-Side-Angle
Option A; Corresponding congruent Angle-Side-AngleOption B; Corresponding congruent Side-Angle-Side
Option A; Corresponding congruent Angle-Side-AngleOption B; Corresponding congruent Side-Angle-SideOption D: 3 congruent sides
There are some congruence theorems that prove that two triangles are congruent and they are;
1) SSS; This means Side - Side - Side and it denotes that the 3 corresponding sides of both triangles are congruent.
2) SAS; This denotes Side - Angle - Side and it denotes that the 2 corresponding sides and the included corresponding angle are congruent.
3) ASA; This denotes Angle - Side - Angle and it means that the 2 corresponding angles and the included corresponding side are congruent.
4) AAS; This denotes Angle - Angle - Side and it denotes that the 2 corresponding angles and corresponding non-included side are congruent.
In conclusion, from the options, options A, B & D.

A. Domain: x>3 Range: y2 -2
B. Domain: x2 -2 Range: y> 3
C. Domain: x>-2 Range: y> 3
D. Domain: x2 3 Range: y> -2
Answer:

Step-by-step explanation:
I don't know for sure tho
Using inverse function concepts, the correct option is:
B. Domain: x < -2 Range: y> 3
--------------------------
The domain of a function is the set that contains all possible input values.The range of a function is the set that contains all possible output values.In the inverse function, input and output are exchanged, thus, domain and range are also exchanged.For the original function, the domain is x > 3 and the range is y < -2.Thus, for the inverse function, the domain is x < -2 and the range is y > 3, which means that option B is correct.A similar problem is given at https://brainly.com/question/24603090

Which row of the table reveals the y-intercept of function f?
Answer:
second row x=0 f(x)=2
Step-by-step explanation:
when x= 0 the f(x) = y-intercept
Second row of the table reveals the y-intercept of function f.
What are intercepts?The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.
According to the question
Y intercept of the function f :
y-intercept is the point where a line crosses the y-axis.
i.e x = 0

Answer:
A = 37°B = 63°C = 16°Step-by-step explanation:
The tangent function relates an angle to the measures of its adjacent and opposite sides. The inverse tangent (arctan) function can be used to find the angle from its tangent value.
Tan = Opposite/Adjacent
angle = arctan(opposite/adjacent)
A = arctan(3/4) ≈ 37°
B = arctan(2/1) ≈ 63°
C = arctan(2/7) ≈ 16°

The length of cell A is 8x10 to the power of negavtive 6 m. The length of cell B is0.0000004 m. What is the ratio of cell A's length to cell B's length? Use pencil and paper. Is it easier to find the ratio when the numbers are expressed in scientific notation or in standard form? Explain your reasoning.
Answer:
Ratio of length of cell A to cell B is 20 : 1
Step-by-step explanation:
Length of cell A = [tex]8\times 10^{-6}[/tex] m
Length of cell B = 0.0000004 m
Convert the length of cell B into scientific notation.
Length of cell B = [tex]4.0\times 10^{-7}[/tex]
Now the ratio of the lengths of cell A and cell B = [tex]\frac{8.0\times 10^{-6}}{4.0\times 10^{-7}}[/tex]
= [tex]2\times 10^{7-6}[/tex]
= 20
Therefore, ratio of length of cell A to cell B is 20 : 1
