Answer:
independent variable = Time
Dependent variable = texting speed
Step-by-step explanation:
The Independent and dependent variables are used in regression analysis for making prediction. The Independent variable also called the predictor are the variables or data collected in other to influence or determine the outpjt obtained which is the dependent or predicted variable. Hence, the aim or prediction we wish to obtain, measure or determine is the dependent variable In the scenario above, the aim of the data collected is to determine the typing skill, here, the dependent variable is the typing skill. The data required to define the bthis is the data collected on typing speed which measures time taken to type.
Therefore, independent variable = Time
Dependent variable = texting speed
Evaluate. 2.2^3 . 2^-5 .2^-1
A. -4
B, -8
C. 1/4
D. 1/8
Answer:
Step-by-step explanation:
2^3 . 2^- 5 . 2^- 1
= 2^( 3 - 5 - 1 )
= 2^( 3 - 6 )
= 2^- 3
= 1 / 2^3
= 1 / 8
If
2 . 2^3 . 2^- 5 . 2^- 1
= 2^1 . 2^3 . 2^- 5 . 2^- 1
= 2^( 3 - 5 - 1 + 1 )
= 2^( 3 - 5 )
= 2^- 2
= 1 / 2^2
= 1 / 4

area of rectangle=length x width
7x20=140
area of square = side^2
5x5=25
140+25=165
hope that answers your question
Step-by-step explanation:
Answer:
165 in^2
Step-by-step explanation:
Split the polygon and make 1 rectangle and 1 square.
Now you got a 5x5 square and a 7x20 rectangle
Do the square one first...
5 x 5=25 in
Now do the rectangle one...
7 x 20=140 in
Last add them...
25+140=165 in^2
Hope this helps!!

A line passes through the points (4, -1) and (2,3). What is the slope of the line?
-2. 2
1/2
-1/2
Answer:
-2
Step-by-step explanation:
To find the slope of a line with 2 given points, you use the formula
m=y2-y1/x2-x1
Now you plug in the points which would be m=3-(-1)/2-4 which equals m=4/-2
4/-2 equals -2
The slope is -2

The question: 2m^3-2m^2+3-3m
The answer is supposed to be: (2m^2-3)(m-1)
I do need steps
Thx
Answer:
(2m^2-3)(m-1)
Step-by-step explanation:
2m^3-2m^2+3-3m
2m^3-2m^2-3m+3
2m^2(m-1)-3(m-1)
(2m^2-3)(m-1)
Answer:
(2m^2-3)(m-1)
Step-by-step explanation:
2m^3-2m^2+3-3m
=(2m^3-2m^2)+(3-3m)
=2m^2(m-1)+3(1-m)
=(m-1)(2m^2-3)
=(2m^2-3)(m-1)

∛44x-7 -5=0 find the x
Answer:
x = 3.
Step-by-step explanation:
(∛44x - 7) - 5 = 0
Cube the expression.
44x - 7 - 125 = 0
Subtract.
44x - 132 = 0
Add 132 to both sides.
44x = 132
Divide by 44.
x = 3.
Proof:
(∛44x - 7) - 5 = 0
(∛44(3) - 7) - 5 = 0
(∛132 - 7) - 5 = 0
(∛125) - 5 = 0
5 - 5 = 0
0 = 0

Answer:
Part A: One.
Part B: (3, 5)
Step-by-step explanation:
Part A: A solution to a pair of equations is generally where the two functions intersect. As we can see, a graph is provided, so things are facilitated. We can see that they only intersect once, which means only one answer.
Part B: The solution, which as we have learned is where the two lines intersect, is (3, 5), as that is, again, the point of intersection.

there are twelve total combinations
Step-by-step explanation:
just by looking at the problem though,
ABCD
AB
AC
AD
BA
BC
BD
CA
CB
CD
DA
DB
DC
normally, because some of them are repeated, we need to get rid of some
AB
AC
AD
BC
BD
DC
since this is about passwords though, we need to keep all of the same twelve combinations because the order of the letters are important

How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

Answer:
7(left answer), 3(top left answer), and 10(top right answer)
Step-by-step explanation:
So what are two things that go into 21?
21 and 17 and 3Out of those two, which is a factor of 70? Right off the bat we know 7 is.
THis isnt the greatest factor of 70, but it is for both 21 and 7, so now we know the left answer for hieght is 7.
Now 3 must be the top left answer, because you must make 21 with 7. 7 Goes into 21 3 times, so it has to be 3. So now we know that the top left anhswer is 3.
Finally we have our top right answer. We already know that the height is 7, now we need to find the width. All we have to do is divide 70 by the 7 heigh, and we will find our width:
70/7
=
10
So now we know that the top right answer is 10.
Sorry that you couldnt get a real answer from people, I hope this is in time to help!

suzanne is running a 5km race. so far she has ran 1,250m. how many more meters does she need to run to complete the race?
Answer: 3750 m
Step-by-step explanation:
Remember that there are different units; one is in km and the other is in m
I’ll go from km to m
1 km = 1000 m
Therefore 5 km = 5 x 1000 m
5km = 5000 m
Now, we just subtract to find how much more Suzanne have to run
5000 m - 1250 m = 3750 m
