The scale is likely to show the mass is either 270.9g or 245.1g
Step-by-step explanation:
Actual mass = 258g
Percent error = 5% = ±0.05
Mass shown by scale = Actual mass*percent error
[tex]Mass\ shown\ by\ scale=258*(\±0.05)\\Mass\ shown\ by\ scale=\±12.9g[/tex]
Therefore,
Mass shown by scale = 258+12.9 , Mass shown by scale = 258-12.9
Mass shown by scale = 270.9g , Mass shown by scale = 245.1g
The scale is likely to show the mass is either 270.9g or 245.1g

Each month the stock decreased in value.
On January 1 it was worth $8,474.
On March 1 it was worth $3,323.
During February it decreased by $1,621.
During January it decreased by $_____.
Answer:
During January it decreased by $3,530.
Step-by-step explanation:
Given data:
Value of stocks in January 1st = $8,474
Value of stocks on March 1st = $3,323
Decrease value during February = $1,621
To find the decrease value during January.
Solution:
Let the decrease value in dollars during January be = [tex]x[/tex]
So, value of stocks in dollars on 1st February will be = [tex]8474-x[/tex]
So, value of stocks in dollars on 1st March will be = [tex]8474-x-1621[/tex]
So, we have
[tex]8474-x-1621=3323[/tex]
[tex]6853-x=3323[/tex]
Subtracting both sides by 6853.
[tex]6853-x-6853=3323-6853[/tex]
[tex]-x=-3530[/tex]
Multiplying both sides by -1.
∴ [tex]x=3530[/tex]
Thus, during January it decreased by $3,530.

Answer:
D
3. Reflexive Property of (Congruence) ≅
4. SSS (Side to Side to Side Congruence rule)
Step-by-step explanation:
3. Any geometric figure compared to itself is congruent to itself so this is why:
[tex]\overline{AC}\cong \overline{CA}\\\angle B\cong \angle B\\(...)[/tex]
4. Since we have a parallelogram, therefore we can say:
[tex]\overline{BC}\cong \overline{DA}\\\\\overline{BA}\cong \overline{DC}\\\\\overline{CA}\cong \overline{AC}\\[/tex]
Both triangles ABC and CDA satisfy the side to side to side congruence, since their 3 sides are congruent.
So, It's D.
P.S.
Notice that the angle measure information is not included in the data above that's why we cannot say it is SAS congruence.

Answer:
y = 2x
Step-by-step explanation:
Note the relationship between x and y, that is
x = - 42 → y = - 84 ← that is y = 2x
x = - 14 → y = - 28 ← that is y = 2x
x = 14 → y = 28 ← that is y = 2x
x = 42 → y = 84 ← that is y = 2x
Thus the linear equation is y = 2x
Answer:
y = 2xStep-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the table we have the points (14, 28) and (42, 84).
Substitute:
[tex]m=\dfrac{84-28}{42-14}=\dfrac{56}{28}=2[/tex]
Put the val;ue of a slope and the coordinates of the point (14, 28) to the equation of a line:
[tex]28=2(14)+b[/tex]
[tex]28=28+b[/tex] subtract 28 from both sides
[tex]28-28=28-28+b\\\\0=b\to b=0[/tex]
Finally we have:
[tex]y=2x+0=2x[/tex]
least to greatest -4.3, -82.5, -41 4/5, -13 1/8
-82.5, -41 4/5, -13 1/8, -4.3
Final answer:
To arrange the numbers from least to greatest, you order them based on their value on the number line, with larger negative values representing smaller quantities. The numbers from least to greatest are -82.5, -41 4/5, -13 1/8, and -4.3.
Explanation:
To arrange the numbers -4.3, -82.5, -41 4/5 (which is -41.8), and -13 1/8 (which is -13.125) from least to greatest, we must compare their values on the number line. Larger negative numbers are those with the greater absolute value or those that are farther from zero in the negative direction.
Focusing on the given numbers:
-82.5 is the largest negative number, so it is the least.
-41 4/5 (or -41.8) is next, being less negative than -82.5.
-13 1/8 (or -13.125) is less negative than both -82.5 and -41.8.
-4.3 is the smallest negative number, so it is the greatest of the negatives.
Therefore, when ordered from least to greatest, the numbers are:
-82.5
-41 4/5
-13 1/8
-4.3

The sum of 5 consecutive odd numbers is 145
The sum of 5 consecutive odd integers is 145. These are the other 4 consecutive odd numbers. Now if we add all of these up we will get this : 25 + 27 + 29 + 31 + 33 = 145.
Hope I helped! ☺☼
The five consecutive odd numbers that sum up to 145 are 25, 27, 29, 31, and 33.
Let's call the middle of the five consecutive odd numbers n. Because these numbers are odd and consecutive, the two numbers before n will be n-2 and n-4, and the two after will be n+2 and n+4. The sum of these five numbers is:
n-4 + n-2 + n + n+2 + n+4 = 5n.
Since the sum of the five numbers is 145, we have:
5n = 145.
To find the value of n, we divide both sides by 5:
n = 145 / 5,
n = 29.
So the middle number is 29, and the five consecutive odd numbers are 25, 27, 29, 31, and 33.
The above question is incomplete, the complete question is:
The sum of 5 consecutive odd numbers is 145. find the numbers.

Which measure of variability can be compared using the box plots?
Box plots are useful for comparing the measure of variability in datasets. Specifically, they compare the interquartile range (IQR), which is the range covering the middle 50% of a dataset. This is represented by the box in the plot, and additional info like median and potential outliers are also shown.
In the field of statistics, box plots, also known as box and whisker plots, are useful for comparing the measure of variability in a data set. The specific measure of variability that can be compared using the box plots is called the interquartile range (IQR).
The IQR is the range within which the middle 50% of a dataset falls. It is calculated by subtracting the lower quartile (25th percentile) from the upper quartile (75th percentile). These quartiles are represented on a box plot by the edges of the box, which makes it easier to visually compare the variability of different datasets.Box plots also present additional information like median and potential outliers in the data.

Answer:
In descending order the function are represented as [tex]D>F>A>B>E>C[/tex]
Step-by-step explanation:
Whether it is increasing or is the larger or smaller number it all depends on its slope.
Equation of line [tex]y=m(x)+c[/tex],and [tex]m[/tex] is the slope.
So we will work with the slopes of each equations and arrange them in descending order.[Greater to larger number sequence]
Slopes are [tex]\frac{4}{3}, \frac{5}{4}, \frac{-2}{1},\frac{7}{4}, \frac{6}{5}, \frac{8}{5}[/tex]
We will equate the denominator by taking LCD of it then multiply numerator and denominator with a fix number which can bring all the denominator same.
LCD of the denominator [tex](1,3,4,5)=60[/tex]
Example:
[tex]\frac{4}{3}=\frac{4\times 20}{3\times 20}= \frac{80}{60}[/tex]
Similarly we will equate all the fractions.
So the slope are [tex]\frac{80}{60}, \frac{75}{60}, \frac{-120}{60},\frac{105}{60}, \frac{72}{60}, \frac{96}{60}[/tex]
In descending order the numbers are:
[tex]\frac{105}{60},\frac{96}{60}, \frac{80}{60}, \frac{75}{60},\frac{72}{60},\frac{-120}{60}[/tex]
According to the option the right choice are as follows:
[tex]D>F>A>B>E>C[/tex]
To find increasing functions, examine the slope of each equation, which must be positive for the function to be increasing. Functions A, B, D, E, and F are increasing, with D having the largest unit rate. C is a decreasing function and is not classified with the others.
Explanation:To determine which functions are increasing, we look at the coefficient of x in each equation since that represents the slope of the line. For a function to be increasing, its slope (unit rate) must be positive. Comparing the slopes will help us classify each function as having a larger unit rate or a smaller unit rate than the function represented in the graph. Without the specific function from the graph for comparison, we'll just compare the given functions to each other.
A. y=4/3x-5/3: Increasing function with a slope of 4/3.B. y=5/4x-3: Increasing function with a slope of 5/4.C. y=-2x+17/3: Decreasing function with a negative slope; not an increasing function.D. y=7/4x-9/4: Increasing function with the largest slope of 7/4.E. y=6/5x-3/5: Increasing function with a slope of 6/5.F. y=8/5x-7/5: Increasing function with a slope of 8/5, which is larger than A and E but smaller than D.Based on the slopes, D has the largest unit rate, followed by F, A, B, and E, in that order. Function C is not increasing and thus not part of this classification.

A construction crew can clear 1/2 ton of dirt in 90 minutes. How much dirt can they clear in 4 hours?
Answer:
4/3t
Step-by-step explanation:
1/2t.........90m
x t.............4h->240m
x=(240m*1/2t)/90m
x=120/90
x=4/3t
The construction crew can clear 8/3 tons of dirt in 4 hours.
Explanation:To find out how much dirt the construction crew can clear in 4 hours, we need to first determine their rate of clearing dirt. The question states that they can clear 1/2 ton of dirt in 90 minutes. To calculate their rate, we divide the amount of dirt cleared (1/2 ton) by the time taken (90 minutes):
Rate = 1/2 ton / 90 minutes
Simplify the rate:
Rate = 1/2 × 2/90 ton/minute = 1/180 ton/minute
Now, to find how much dirt they can clear in 4 hours, we multiply their rate by the number of minutes in 4 hours:
Dirt cleared = Rate × Time
Dirt cleared = 1/180 ton/mintue × 4 hours × 60 minutes/hour
Simplify the units:
Dirt cleared = 1/180 × 4 × 60 ton
Calculate the result:
Dirt cleared = 8/3 ton
Therefore, the construction crew can clear 8/3 tons of dirt in 4 hours.

Write equation of a line that is parallel to x=8 and the passes through the point ( -3, -2)
Answer:
x = - 3
Step-by-step explanation:
x = 8 is the equation of a vertical line parallel to the y- axis.
Thus a line parallel to it will also be vertical with equation
y = c
Where c is the value of the x- coordinates the line passes through
The line passes through (- 3, - 2) with x- coordinate - 3, thus
x = - 3 ← equation of parallel line
There is no equation of a line that is parallel to x=8 and passes through the point (-3, -2).
Explanation:To find the equation of a line parallel to x = 8 and passing through the point (-3, -2), we need to know that a line with an equation x = a is a vertical line passing through the point (a, 0), and it has no slope. Since we need to find a line with the same slope as x = 8, we can set the equation to x = -3, which represents a vertical line passing through the point (-3, 0).
However, this line is parallel to x = 8 rather than passing through the point (-3, -2). Therefore, there is no equation of a line that is parallel to x = 8 and passes through the point (-3, -2).

Let the equation be written with constant k'
So, y = k x
Or, k = [tex]\dfrac{y}{x}[/tex]
∴ k = [tex]\dfrac{15}{2}[/tex]
Now, again
For x = 8
equation can be written as
y = k x
Or, y = [tex]\dfrac{15}{2}[/tex] × 8

There is 1 red gumdrop and 4 green gumdrops in a small jar. Also, 2 pieces of butterscotch candy and 3 pieces of cinnamon
candy are in another jar. If Craig draws one piece of candy from each jar without looking, what's the probability that he will
get a red gumdrop and a piece of butterscotch candy?
Answer:
The probability that he will get a red gumdrop and a piece of butterscotch candy is 2/25
Step-by-step explanation:
The path to find the answer is to find the probability of both things happening and then multiply them. First, there is 1 red gumdrop and 4 green gumdrops in a jar. There are 5 gumdrops total so the probability of choosing a red one is 1/5. Next, there are 2 pieces of butterscotch candy and 3 pieces of cinnamon candy in another jar. There are 5 pieces of candy total so the probability of choosing a piece of butterscotch candy is 2/5. Finally multiply the two probabilities: 1/5 * 2/5 = 2/25.
The probability that Craig will draw a red gumdrop from the first jar and a butterscotch candy from the second jar is 0.08 or 8%.
Explanation:The subject of this problem is probability. Probability refers to the measure of the likelihood that an event will occur in a random experiment. In this specific problem, Craig randomly chooses one candy from each jar. We want to find the likelihood that Craig will choose one red gumdrop and one piece of butterscotch candy.
There are a total of 5 gumdrops in the first jar, with 1 being red. Thus, the probability of choosing a red gumdrop is 1/5. In the second jar, there are a total of 5 pieces of candy, with 2 being butterscotch. As such, the probability of choosing a butterscotch candy is 2/5.
To calculate the total probability, you multiply both probabilities, getting a final probability of (1/5) * (2/5) = 2/25 = 0.08. This means that there is an 8% chance that Craig will draw a red gumdrop and a butterscotch candy.
