The rate of work fo the company is 3.78 metric tons per hour.
How to find the rate of work per hour?We know that the company can remove (8 + 1/2) metric tons in a time of (2 + 1/4) hours.
To find the rate of work, we need to take the quotient between the number of metric tons and the time in hours, to do so we can write our numbers as single numbers instead of mixed ones:
(8 + 1/2) metric tons = 8.5 metric tons.
(2 + 1/4) hours. = 2.25 hours
Then the rate of work is:
R = 8.5/2.25 = 3.78 metric tons per hour.

On a coordinate plane, a red curved line with an upward arc, labeled g of x, crosses the x-axis at (negative 2, 0), and the y-axis at (0, 4). A blue curved line with an upward arc, labeled f of x, crosses the y-axis at (0, 4) and the x-axis at (2, 0). Which statement is true regarding the graphed functions?
A. f(0) = 2 and g(–2) = 0
B.f(0) = 4 and g(–2) = 4
C. f(2) = 0 and g(–2) = 0
D. f(–2) = 0 and g(–2) = 0
Answers
Answer:
Your answer is A.
Hope this helps!
Step-by-step explanation:
Because g(x) is (-2, 0 ) and (0, 4 ). So the slope is 4/2 or 2. Then you can figure out the equation for g(x) which is g(x) = 2x + 4.
f(x) is (0, 4 ) and (2, 0 ) so the slope is 0 - 4 / 2 - 0 which is -4/2 or -2. Then figure out the equation for f(x) which is f(x) = -2x + 2.
Now with the two equations, you can just go through the answers so
f(0) = 2 -> f(0) = -2(0) + 2 which equals 2.
g(-2) = 0 -> g(-2) = 2(-2) + 4 which equals 0. So this answer is right.

What does intersect mean in math?When two or more lines cross each other in a plane, they are called intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is called the point of intersection. Here, lines P and Q intersect at point O, which is the point of intersection.
What is the intersection of a curve?In general, an intersection curve consists of the common points of two transversally intersecting surfaces, meaning that at any common point the surface normals are not parallel. This restriction excludes cases where the surfaces are touching or have surface parts in common.

pure salt is to be added to a 10% salt mix to get 9 ounces of a 20% salt mix. how much of each salt should be used
Answers
Step-by-step explanation: You should be using 8 Oz of pure salt.
In the mixture there is 1 ounce of pure salt and 8 ounces of salt mix.
Given that, pure salt is to be added to a 10% salt mix to get 9 ounces of a 20% salt mix.
What are mixed problems?Mixture problems are word problems where items or quantities of different values are mixed together. Sometimes different liquids are mixed together changing the concentration of the mixture.
Lets the pure salt=x ounces
Then, the salt mix=9-x ounces
Now, an equation is
x+10% of (9-x)=20% of 9
⇒ x+0.1(9-x)=0.2×9
⇒ x+0.9-0.1x=1.8
⇒ 0.9x=0.9
⇒ x=1 ounces
Then, salt mix=9-1=8 ounces
Therefore, in the mixture there is 1 ounce of pure salt and 8 ounces of salt mix.

Answers
The equation of a line can be written using the slope-intercept form given as
\(y=mx+c\)For that equation, we need to find m (rate of change) and c (y-intercept).
To find m, we can use the formula
\(m=\frac{y_2-y_1}{x_2-x_1}\)Let us pick any two points on the graph such that
\(\begin{gathered} (x_1,y_1)\Rightarrow(-2,10.0) \\ \text{and} \\ (x_2,y_2)\Rightarrow(1,2.5) \end{gathered}\)Substituting these into the equation, we have
\(\begin{gathered} m=\frac{2.5-10.0}{1-(-2)} \\ m=-\frac{5}{2} \end{gathered}\)The intercept, c, can be calculated by substituting the rate of change, m, and any point coordinates to the equation of a line.
Let us pick the point
\((x,y)=(0,5.0)\)Substituting, we have
\(\begin{gathered} 5=(-\frac{5}{2}\times0)+c \\ \therefore \\ c=5 \end{gathered}\)Therefore, we have the equation of the line to be
\(y=-\frac{5}{2}x+5\)Multiplying all terms by 2 to clear out the fraction, we get the equation to be

Answers
The critical value of the statistic for testing the hypothesis of equal treatment means at the 0.05 significance level is approximately option (a) 3.84
To find the critical value of the statistic for testing the hypothesis of equal treatment means at the 0.05 significance level, we can use an analysis of variance (ANOVA test) test
First, we need to calculate the total sum of squares (SST), which represents the total variability in the attendance data:
SST = ∑∑(Xij - X..)2
= (25-31.83)2 + (30-31.83)2 + ... + (30-31.83)2
= 351.83
where Xij is the attendance for the ith day and jth class time, X.. is the grand mean attendance, and the summation is over all observations.
Next, we need to calculate the between-groups sum of squares (SSG), which represents the variability in the attendance data that is due to differences between the class times
SSG = (∑nj(X.j - X..)2) / k
= [(25-32.17)2 + (30-32.17)2 + ... + (30-32.17)2 + (25-32.17)2 + (30-32.17)2 + ... + (30-32.17)2 + (25-32.17)2 + (30-32.17)2 + ... + (40-32.17)2] / 3
= 189.5
where nj is the number of observations for the jth class time, k is the number of groups (i.e., class times), and X.j is the mean attendance for the jth class time
Finally, we can calculate the within-groups sum of squares (SSW), which represents the variability in the attendance data that is due to differences within each class time:
SSW = SST - SSG
= 351.83 - 189.5
= 162.33
The degrees of freedom for the ANOVA test are:
dfG = k - 1 = 3 - 1 = 2 (degrees of freedom for the between-groups sum of squares)
dfW = N - k = 15 - 3 = 12 (degrees of freedom for the within-groups sum of squares)
dfT = N - 1 = 15 - 1 = 14 (total degrees of freedom)
where N is the total number of observations.
The F-statistic for the ANOVA test is
F = (SSG / dfG) / (SSW / dfW)
= (189.5 / 2) / (162.33 / 12)
= 5.87
To find the critical value of the F-statistic for testing the hypothesis of equal treatment means at the 0.05 significance level, we can look it up in an F-distribution table with dfG = 2 and dfW = 12. At the 0.05 level of significance, the critical value of the F-statistic is approximately 3.84.
Therefore, the correct option is (a) 3.84

Answer:
2(x+4) -6 = 5x-17

Answers
Using net worth statement, Andre's net worth is $159,573.
How to Construct a net worth statement to find Andre's net worth.Andre's net worth can be calculated by subtracting his total liabilities from his total assets.
Total assets = $155,000 (condominium) + $8,100 (stock portfolio) + $9,100 (car value) + $2,600 (bank account) = $174,800
Total liabilities = $3,300 (car loan) + $7,600 (student loans) + $4,327 (credit card balance) = $15,227
Net worth = Total assets - Total liabilities = $174,800 - $15,227 = $159,573
Therefore, Andre's net worth is $159,573.

What is the area of this trapezoid?

Answers
Therefore, the area of the trapezoid is 1338 3/4 square units.
A quadrilateral with at least one set of parallel sides is known in geometry as a trapezium, or trapezium in British and other versions of English. In Euclidean geometry, a trapezium is invariably a convex quadrilateral. The trapezoid's parallel sides are referred to as its bases.
To find the area of a trapezoid, we use the formula:
Area = (1/2) × (sum of parallel sides) × (height)
In this case, we have the following information:
The two parallel sides are 12 1/4 and 24 1/4.
The height is 73 1/2.
First, we need to add the two parallel sides to find the sum:
12 1/4 + 24 1/4 = 36 1/2
Next, we can plug these values into the formula:
Area = (1/2) × 36 1/2 × 73 1/2
Area = 1338.75

The mean replacement time for a random sample of 21 microwave ovens is 8.6 years with a standard deviation of 2.7 years. Construct the 98% confidence interval for the population variance, Assume the data are normally distributed
Answers
The 98% confidence interval for the population variance of microwave oven replacement times is approximately (3.248, 14.054) years².
To construct the 98% confidence interval for the population variance of microwave oven replacement times, we'll use the chi-square distribution and the given information:
Sample size (n) = 21
Sample mean = 8.6 years
Sample standard deviation (s) = 2.7 years
First, find the degrees of freedom (df) using the formula:
df = n - 1 = 21 - 1 = 20
Next, find the chi-square values for the 98% confidence interval using a chi-square table or calculator. For a 98% confidence interval and 20 degrees of freedom:
Lower chi-square value (χ2L) = 8.260
Upper chi-square value (χ2U) = 35.479
Now, use the formula to calculate the confidence interval for the population variance (σ²):
Lower limit: (n - 1) × s² / χ2U = (20) × (2.7)² / 35.479 ≈ 3.248
Upper limit: (n - 1) × s² / χ2L = (20) × (2.7)² / 8.260 ≈ 14.054
Therefore, the 98% confidence interval for the population variance of microwave oven replacement times is approximately (3.248, 14.054) years².
