rearrange w= 3(2a+b) -4 to make a the subject
Answer:
a = - 1/2b + 1/6w + 2/3
Step-by-step explanation:
w= 3(2a+b) - 4
Add 4 on both sides.
w + 4 = 3(2a+b)
Divide 3 into both sides.
w/3 + 4/3 = 2a+b
Subtract b on both sides.
w/3 + 4/3 - b = 2a
Divide 2 into both parts.
w/3/2 + 4/3/2 - b/2 = a
a = w/6 + 4/6 - b/2
a = 1/6w + 2/3 - 1/2b
Answer:
a=(w-3b+4)/6
Step-by-step explanation:
w= 3(2a+b) -4
w=6a+3b-4
6a= w-3b+4
a=(w-3b+4)/6

Answer:
4.4
Step-by-step explanation:
Write the question out as an equation:
7+x/3 = 2x - 5
Rearrange , simplify and solve:
7+x = 3(2x-5) = 6x - 15
7+x = 6x-15
6x - 15 = 7+x
6x = 7+x+15 = 22+x
6x = 22+x
6x-x = 22
5x = 22
x = 4.4

Step-by-step explanation:
Answer: a) increases
b) decreases
c) remains the same
Step-by-step explanation:
a) As time increases, the distance traveled increases because you are traveling from home to work at a rate of 500 ft/min
b) As time increases, the distance remaining decreases because you are getting closer to your goal of 10,000 ft
c) As time increases, the distance from home to work remains the same because the distance from point A (home) to point B (work) hasn't changed - only YOUR distance between them has changed.

THIS IS THE COMPLETE QUESTION;
A school creates a histogram representing the individual travel times for students riding the bus to school. The histogram is right-skewed, and the mean time is 25 minutes.
Which statement best describes the possible value of the median time of students riding the bus to school?
The median time is less than 25 minutes.
The median time is exactly equal to 25 minutes.
The median time is approximately equal to 25 minutes.
The median time is greater than 25 minutes.
Answer;
The median time is less than 25 minutes
Step-by-step explanation
✓When the histogram is skewed right, it implies that the mean is greater than the median which means The median time is less than the mean.
This is as a result of few large values that drive as a result of skewed-right data
✓Skewness can be explained as measure of the asymmetry of a histogram When a histogram is symmetrical when it has a normal distribution, i.e when the same amount of data falls on both sides of the mean. Ahistogram has a normal distribution will have a skewness of 0.
✓the skewness can be explained in terms positive/right relationship:
√nonparametric skew implies that the mean is greater than the median, which means it is at the the right.
√A negative/left nonparametric skew can be explained as when the mean is < the median. I e it fall to the left .
Therefore, the median is less than 25 minutes
The statement that most adequately recounts the likely value of median time:
A). The median is less than 25 minutes.
What is the Median?Median is defined as the number that isolates the first and later half of a set of given distribution or number.
As per the question, the bend in the histogram towards the right side signals that the mean value is significantly higher than the median.
The cause behind this is that the greater values have caused this influence.
Hence, this implies that the median values are lesser by the time of 25 minutes.
Thus, option A is the correct answer.

How did the temperature change if: at first it increased by 25 % and then decreased by 40% ?
Answer:
Decreased by 25%
Step-by-step explanation:
Let's take 100 for example.
Step 1: 25% of 100 is 25
Step 2: 100 + 25 = 125
Step 3: 40% of 125 is 50
Step 4: 125 - 50 = 75
Step 5: 75 is N of 100
Step 6: N = 75%
Step 7: 100% - 75% = 25%
Decreased by 25%.
The temperature change is decreased by 25%
What is percentage?Percentage is defined as ratio expressed as a fraction of 100.
Let the temperature is T
Temperature increased by 25 %
25% of T is 0.25T
T + 0.25T = 1.25T
Temperature decreased by 40 %
40% of 1.25T is 0.5T
1.25T - 0.5T = 0.75T
Since initial temperature = T
Now, final temperature = 0.75T
T - 0.75T = 0.25T
Hence, the temperature change decreased by 25%

Answer:
x = 12y = 4√3Step-by-step explanation:
To find x we use cosine
cos∅ = adjacent / hypotenuse
x is the adjacent
8√3 is the hypotenuse
cos 30 = x / 8√3
x = 8√3 cos 30
x = 12To find y we use sine
sin∅ = opposite / hypotenuse
y is the opposite
8√3 is the hypotenuse
sin 30 = y / 8√3
y = 8√3 sin 30
y = 4√3Hope this helps you

Step-by-step explanation:
[tex]g(x)=\dfrac{x+3}{x^2+2x-2}\qquad =\dfrac{x+3}{(x+3)(x-1)}[/tex]
Set the denominator equal to zero and solve for x. These are the asymptotes: x = -3 and x = 1
Notice that (x+3) cancels out from the numerator and denominator
This becomes a Removable Discontinuity, instead of an asymptote.
⇒ Therefore, x = 1 is the vertical asymptote
x = -3 is a removable discontinuity

A 45 foot ladders leaning up against a building. The base of the latter is 20 feet away from the building. What is the angle of elevation to the top of the building
Answer:
The angle of elevation to the top of the building is 63.61 degrees
Step-by-step explanation:
Here, we want to calculate angle of elevation to the top of the building.
For this, we need a triangle
Please check for this in the attachment.
From the diagram, we are to calculate the angle theta.
To do this, we use trigonometric identities.
Looking at what we have, we have the hypotenuse and the adjacent.
So the trigonometric identity to use is the cosine
Mathematically Cosine theta = adjacent/hypotenuse
Thus, Cos theta = 20/45
Cos theta = 0.444444444444444
Theta = Arc cos(0.444444444444444)
Theta = 63.61 degrees
It is worked out that if 3 ladles full of soup are given to each person, 160 people can be fed. The costumers complained in the past that the proportions are too small. The cool decides to give 5 ladles full of soup to each person. How many people can now be fed
Answer:
96 people
Step-by-step explanation:
Here, we have 3 ladles feeding 160 people, we now want to calculate the number of people 5 ladles will feed.
First, we need to calculate the total number of ladles that fed the 160
people
That would be 3 * 160 = 480 ladles
Now we increased their number of ladles to 5, the number of people we would be feeding is 480/5 = 96 people

[tex]p_{hat}[/tex] ± [tex]z.\sqrt{\frac{p_{hat}(1-p_{hat})}{n} }[/tex]
[tex]p_{hat}[/tex] is the proportion of seals who are earless.
[tex]p_{hat}[/tex] = [tex]\frac{167}{298}[/tex] = 0.56
z is z-score for 90% CI: z = 1.645
Calculating:
[tex]\frac{167}{298}[/tex] ± [tex]1.645.\sqrt{\frac{0.56(0.44)}{298} }[/tex]

A line connecting the coordinates (-4, 0), and (0, 2) on a coordinate plane will serve as the equation's representation in graph 4.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, a linear function that has a slope of 0.5 and a y-intercept of 2.
thus the equation of line as slope-intercept:
y = mx + c
y = 0.5x + c
Since Y-intercept is 2 thus line passes through (0, 2)
from the equation
2 = 0.5 * 0 + c
c = 2
Equation of the line:
y = 0.5x + 2
Therefore, On a coordinate plane, a line goes through points (negative 4, 0) and (0, 2) and graph 4 will represent the equation.

Step-by-step explanation:
It's essential that you use parentheses to clarify what's happening here:
