During a 60-minute period, a traffic engineer counted 54 trucks and cars that crossed a bridge. The ratio of trucks to cars that travel across the bridge is usually 2:7. The equation LaTeX: \frac{2}{7}=\frac{t}{54-t}2 7 = t 54 − t can be used to predict the number of trucks, t, the engineer should have counted. How many trucks should the engineer have counted?
Answer:
Step-by-step explanation:
Given the expression for the equation representing the prediction of number of trucks as;
2/7 = t/54-t where t is the number of trucks
To get the number of trucks t, we will have to evaluate the expression and solve for t as shown;
Given 2/7 = t/54-t
Cross multiply
2(54-t) = 7t
Open the parenthesis
2(54)-2t = 7t
108-2t = 7t
7t+2t = 108
9t = 108
Divide both sides by 9
9t/9 = 108/9
t = 21
Hence the engineers should have counted 21trucks
A bag contains three blue marbles, five red marbles, and four green marbles.
Part A: What is the probability of selecting a red marble?
Part B: What is the probability of selecting three red marbles without replacement?
Part C: In a short paragraph, explain in your own words your work to Step B
Answer:
Below.
Step-by-step explanation:
The total number of marbles is 12.
Part A.
Prob(Red marble) = 5/12.
Part B.
Prob(pick 3 red marbles without replacement) = 5/12 * 4/11 * 3/10 = 1/22.
Part C.
The probability of the first being red is 5/12 because there are 5 red out of a total of 12 marbles. After that there are only 4 marbles and the total is 11 ( 1 marble less). Finally on the 3rd pick there are 3 red and a total of 10. WE then multiply these 3 probabilities.

Answer:
slope is -2/5
y-intercept is 4
Answer:
See Below
Step-by-step explanation:
Ok, so slope intercept form is:
y = mx +b
Where m = slope and b = your y-intercept
lets line them up
y = mx + b
y =-2/5 x + 4
Notice that the m and b are lined up each corresponding #.
Therefore,
m = -2/5
B = 4
Slope = -2/5
y - intercept = 4

What is the probability of spinning a C?
Answer: 37.5%
Step-by-step explanation: Since there are 3 spaces for C it would be 3/8 for the amount of C's in all of the letters.
3/8 = 0.375 = 37.5%
Hope this helps!
The probability of spinning C will be 3/8 or 0375.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
The spinner has eight equal section. And the 8 sections are marked as A, B, B, B, A, C, C, and C.
Then the total number of the event will be
Total event = 8 {A, B, B, B, A, C, C, C.}
Then the probability of spinning C will be
The favorable event will be
Favorable event = 3 {C, C, C}
P = 3 / 8
P = 0.375
The probability of spinning C will be 3/8 or 0375.

Write the slope-intercept form of the equation of the line described.
Through (-2, -1) and parallel to y=-2x-1
Answer:
y= -2x -5
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope and c is the y-intercept.
Parallel lines have the same slope.
Thus, to find the value of the slope of the line, we have to find the slope of the given line.
y= -2x -1
Since the coefficient of x is -2 and the equation is already in slope-intercept form, the slope of the given line is -2.
Substitute m= -2 into the equation:
y= -2x +c
To find the value of c, substitute a pair of coordinates.
When x= -2, y= -1,
-1= -2(-2) +c
-1= 4 +c
c= -1 -4 (-4 on both sides)
c= -5
Thus, the equation of the line is y= -2x -5.

Based on the histogram, which of the following values could represent Q3?
Relative Frequency
(A) 0.24
(B) 0.63
(C) 0.67
(D) 0.71
(E) 0.75
For the given table, the third quartile is given by:
(D) 0.71.
What are the median and the quartiles of a data-set?The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.The first quartile is the median of the first half of the data-set, which is the 25th percentile.The third quartile is the median of the second half of the data-set, which is the 75th percentile.Given a cumulative frequency table, the third quartile Q3 is the value when the sum of the frequencies is of 0.75.
From the frequency table, we have that:
A rate of 0.65 is the 30th percentile.A rate of 0.7 is the 57th percentile, as 0.3 + 0.27 = 0.57.A rate of 0.75 is the 80th percentile, as 0.57 + 0.23 = 0.8.Hence the 75th percentile is between 0.7 and 0.75, meaning that option D is correct.

-7x - 8 = 41x - 8
Add 7x to both sides.

Edwards Manufacturing Company purchases two component parts from three different suppliers. The suppliers have limited capacity, and no one supplier can meet all the company’s needs. In addition, the suppliers charge different prices for the components. Component price data (in price per unit) are as follows:
Supplier
Component 1 2 3
1 $12 $13 $10
2 $15 $12 $10
Each supplier has a limited capacity in terms of the total number of components it can supply. However, as long as Edwards provides sufficient advance orders, each supplier can devote its capacity to component 1, component 2, or any combination of the two components, if the total number of units ordered is within its capacity. Supplier capacities are as follows:

12x + 8y = 24 Convert from standard form to slope-intercept form.
The required equation is y = -(3/2)x + 3 in slope-intercept form.
What is the standard form of linear equations?A linear equation is written in the standard form as Ax + By = C, where A, B, and C are integers and x and y are variables.
For example, 8x + 2y = 7 is the standard form of a linear equation in two variables.
The equation is given in the question, as follows:
12x + 8y = 24
Isolate the variable of y for the above equation,
8y = - 12x + 24
Divided both sides by 8 into the equation,
y = - (12x)/8 + (24)/8
y = -(3/2)x + 3
This equation is in slope-intercept form.
