Test Number of Words Time(minutes)
A. 30. 4
B. 78. 15
C. 99. 22
Answer:
Step-by-step explanation:
To calculate Zane's unit rate/number of words per minute for which each test, we divide number of words in each test by time taken for that test
For test A, unit rate = 30 words/ 4 minutes = 7.5 words per minute
For test B, unit rate = 78 words/15 minutes = 5.2 words per minute
For test C, unit rate = 99 words/22 minutes= 4.5 words per minute
From the above Zane has the highest unit rate in test A and is therefore fastest in test A
Find the equation of a line using y = mx + b given the slope is 2 and the y-intercept is (0,2).
Answer:
y=2x+2
Step-by-step explanation:
y=mx+b where:
m=slope; b=y intercept
Therefore, simply plug in values for (m) and (b)
(m=2); (b=2)
and you're left with the equation (y=2x+2)
Evaluate each side of the equation to determine if the statement is true
If it is true, then type the word true
If it is false, then type the word false.

Julio are you drawing a map of humid. The actual payment has a base of 3000 feet and a height of 1200 feet. Julio needs his drawing to sit on his papers, and he decides to make the base of his triangle 10 inches.
The height of the drawing is 4 inches.
What is the height?A scale drawing is a reduced form in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension
Scale of the drawing = original dimensions / dimensions of the scale drawing
The first step is to determine the scale of the drawing : 3000 / 10 = 300 feet : 1 inch
The second step is to determine the height of the drawing in the map: 1200 / 300 = 4 inches

Find the value of k in the data set so that f(x) is a linear function.
x = {-7, -2, 2, 5}
f(x) = {-15, k, 3, 9}
In order for f(x) to be a linear function, determine the value of k in the data set.
x = {-7, -2, 2, 5}
f(x) = {-15, k, 3, 9}
The value of k is {-5}.
Given that to find the value of k in the data set such that the data set represents a linear function.
Linear Function is a straight line on the coordinate plane is represented by a linear function. The formula for a linear function is f(x) = mx + b, where m and b are real values.
Here, f(x) or y is the dependent variable, m is a slope of the line, x is the independent variable and b is the y-intercept.
Here,(x,f(x)) are {(-7,-15),(-2,k),(2,3),(5,9)}
The slope of the function,
(x, f(x)) = (2,3) and (5,9)
Slope formula is m=[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
Slope m= [tex]\frac{9-3 }{5-2}[/tex]
Slope m=[tex]\frac{6}{3}[/tex]
Slope m=2.
Using the point slope form, determine the linear function's equation.
[tex]y-y_{1} =m(x-x_{1})[/tex]
Here, [tex](x_{1},y_{1})=(-7,-15)[/tex] and m=2
We get
y + 15 = 2 (x + 7)
y = 2x - 1
Now at x = -2 and f(x) = k
k = 2(-2) - 1
k = -4-1
k=-5

Applying the rule of modulus for given values, the expression will result to 20.
What is Modulus or Absolute ValuesThe modulus of a value for example |a|=a if a is greater than or equal to zero
and also
|a|=-a if a is less than zero
In the expression given; the modulus of -6 written as
|-6|=-(-6) this is because the value is less than zero
The modulus of 2 written as; |2|=2 this is because the value is greater than zero. and;
|The modulus of -14 written as; |-14|= -(-14) since the value is less than zero.
Hence, we can rewrite the expression as;
we deal with multiplication first following the rules of BODMAS
2×-(-6)-3×2+[-(-14)]
2×6-6+14
and thus adding values
12+14-6
and finally we subtract;
26-6
which will results to the solution of 20.

C43,500,000 miles
D 435,000,000 miles.
The distance between Earth and Mars in the standard form is 43, 500, 000 miles.
The correct answer is an option (C)
In this question we have been given the distance between Earth and Mars.
The distance between Earth and Mars is approximately 4.35 × 10^7 miles.
We need to write above distance between Earth and Mars in the standard form.
So, we get an expression,
4.35 × 10^7 miles
= 435 × 10^5 miles
= 435 × 100, 000 miles
= 43, 500, 000 miles
Therefore, the distance between Earth and Mars in the standard form is 43, 500, 000 miles.

Graphing the linear functions, it is found that they will have the same height after 5 hours, of 21 inches.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For each function in this problem, we have that:
The initial height is the intercept.The melting rate is the slope.Hence the functions are given as follows:
A(t) = 51 - 6t.B(t) = 36 - 3t.The functions are graphed at the end of the answer, with A(t) in blue and B(t) in black. The intersection of the graphs is at (5,21), which means that they will have the same height after 5 hours, of 21 inches.

true or false: the difference between cross-sectional and time series data is whether the data is evaluated at a single point in time or multiple points in time
The statement "the difference between cross-sectional and time series data is whether the data is evaluated at a single point in time or multiple factors in time" is true.
The distinction between cross-sectional data and time-series data is that time-series data takes into account the identical variables over a period of time, whereas cross-sectional data makes use of specific records for a specific factor in time.
A data set may be both time series and cross sectional.
When the records of go sectional records is regressed, the defined and explanatory variables are all related to the identical single length or point in time.
Time-series and cross-section (TSCS) data collectively are normally analyzed in political technology and associated disciplines.
Therefore, the statement "the difference between cross sectional and time series data is whether the data is evaluated at a single point in time or multiple factors in time" is true.

The Sugar Sweet Company is going to transport its sugar to market. It will cost $3500 to rent trucks plus $225 for each ton of sugar transported. The total cost, C (in dollars), for transporting N tons is given by the following function. C(n)=3500+225n)
Answer:to answer this question you have to look at what the relationship is between tones of sugar and the equation C(n) = 6,500 + 225n. The question gave you a hint in parenthesis in the form of (n) tons. This statement means that the amount of sugar is n so for question 1 the 13 tons is the n value.
Q1:
C(13) = 6,500 + 225*13
C(13) = 6,500 + 2,925
C(13) = 9,425
so what does the 9,425 mean? This is the cost to transport 13 tons of sugar.
Q2:
so this part n is unknown and we are given the C(n) number.
11,450 = 6,500 + 225n
subtract the 6500 from both sides
11,450 - 6,500 = 225n
evaluate
4,950 = 225n
I don't like the n on the right side so I am going to rewrite the equation
225n = 4,950
divide by 225
n = 4,950/225
evaluate
n = 22
So this result means that the company would transport 22 tones of sugar.

pansy measured the height of a window frame as 5.12 feet, but the actual height was 6 feet. what is the percentage of error in pansy's measurement?
The percentage of error in Pansy's measurement is 14.67%
In the given statement is :
Pansy measured the height of a window frame as 5.12 feet, but the actual height was 6 feet.
We know that
Percentage error can be calculated using the formula: (what was measured - the actual measurement) / actual measurement × 100%.
Thus:
The height that was measured = 5.12 feet
Actual measurement of the height = 6 feet
Percentage error = (6 - 5.12) / 6 × 100
Percentage error = 14.67

how to Solve 5 |2x - 1 +20=3
the correct value for x is -1.2, 2.2
Given 5 | 2x - 1 | + 20 = 3
Modulus of a number
The modulus or absolute value, of a number, denoted |x+y| is calculated as
|x + y | =1
x + y = ±1
We need to solve for the value of x
5 | 2x - 1 | = 3 - 20
5 | 2x - 1 | = -17
| 2x - 1 | = - 17 / 5
| 2x - 1 | = - 3.4
2x - 1 = ± (- 3.4)
2x - 1 = -3.4 2x -1 = 3.4
2x = - 3.4 + 1 2x = 3.4 + 1
2x = - 2.4 2x = 4.4
x = - 1.2 x = 2.2

A quarter back is sacked for a loss of 4 yards. On the next play, his team loses 10 yards. Then the the team gains 12 yards on the third play
Answer:
Kindly check explanation
Step-by-step explanation:
Given the question:
Play 1: Quarterback was sacked for a loss of 4 yards
Play 2 : Another loss of 10 yards
Play 3: a gain of 12 yards
Write an addition expression to represent the situation. Then find the sum and explain its meaning.
A loss of 4 yards = - 4
Loss of 10 yards = - 10
Gain of 12 yards = + 12
Addition expression for the scenario :
(-4) + (-10) + 12
Result :
-4 + (-10) + 12
= - 4 - 10 + 12
= - 14 + 12
= - 2
Hence, after two consecutive losses of 4 and 10 yards, the team wins 12 yards on the third play and the aggregate yards lost is reduced to 2 yards.
