ANSWER
[tex]m=\frac{11f+p}{2}[/tex]EXPLANATION
We want to solve for m in the equation:
[tex]2m-p=11f[/tex]This means that we want to make m the subject of formula.
That is:
[tex]\begin{gathered} \text{Add p to both sides of the equation:} \\ 2m-p+p=11f+p \\ 2m=11f+p \\ \text{Divide both sides by 2:} \\ \frac{2m}{2}=\frac{11f+p}{2} \\ m=\frac{11f+p}{2} \end{gathered}[/tex]That is the answer.
What is the quotient of 7.7 x 10^8 and 5.5 x 10^2 expressed in
scientific notation?
The quotient of 7.7 x 10^8 and 5.5 x 10^2 expressed in scientific notation is 1.4x10^6.
What is quotient?
A quotient in mathematics is the amount created by dividing two numbers. The term "quotient" is used frequently in mathematics and is used to describe the integer component of a division (when Euclidean division), as well as a fraction or a ratio (when proper division). A quotient in the second sense is only the proportion of a dividend to its divisor.
Lets calculate the quotient for the value given in question:
[tex]7.7 \times 10^8[/tex]
[tex]5.5 \times 10^2[/tex]
Now we divide the 7.7 by 5.5
[tex]\frac{7.7}{5.5} = 1.4[/tex]
we get value 1.4.
on dividing [tex]\frac{10^8}{10^2}[/tex] we get, [tex]10^6[/tex]
Combining both the value, we get
quotient = [tex]1.4 \times 10^6[/tex]

A fair die is rolled 4 times. What is the probability of having no 1 and no 3 among the rolls? Round your answer to three decimal places.
Answer:
Step-by-step explanation:
You have to assume each roll is independent. The probability of rolling a fair die is 1/6. When you roll the die, you only care about 2,4,5, and 6 since you do not want to get 1 or 3. So the probability is of getting a 2,4,5 and 6 is 4/6.
You could of also see it as the probability of NOT getting a 1 or 3 is:
[tex]1-\frac{2}{6} =\frac{4}{6}=\frac{2}{3}[/tex]
Now you roll the die 4 times with each success being 2/3
[tex]\frac{2}{3} \cdot \frac{2}{3} \cdot \frac{2}{3} \cdot \frac{2}{3} =(\frac{2}{3})^4=.197530864[/tex]

When she sails her boat 700 m closer to the lighthouse, she finds that the angle of elevation is now 5°.
To find:
How tall, to the nearest tenth of a meter, is the lighthouse?
Explanation:

Maggie's brother is 3 years younger than four times her age. The sum of their ages is 42.How old is Maggie?Maggie isyears old.
The age of Maggie is 9 years and her brother whose age 3 years less than four times Maggie's age is 33 years old.
What is age?
Age is the difference in days, months, and years between the day, month, and year of birth and the day, month, and year of the event, expressed in the largest completed unit of solar time, such as years for adults and children and months, weeks, days, hours, or minutes of life, as appropriate, for infants under one year of age (Gregorian calendar).
Let the ages of Maggie and her brother be X and Y.
There are two condition given in the question through which we can form a system of equation containing two equations.
First condition: The sum of their ages is 42.
Therefore,
X + Y = 42
Second Condition: Maggie's brother is 3 years younger than four times her age.
Therefore,
4X - 3 = Y
We get the system of equation:
X + Y = 42
4X - 3 = Y
Solving this system of equation
4X - 3 = Y
4X - 3 = 42 - X
X = 45/5
X = 9
Putting the value of X in one of the equation:
Y = 42 - X
Y = 42 - 9
Y = 33
Therefore, age of Maggie is 9 years and age of her brother is 33 years.

1. Line Q goes through (-6,7) and (4,-2). Write the equation of line Q.
First, find the slope of the line using the slope formula:
Provided two points (a,A) and (b,B) on a line, its slope is given by:
[tex]m=\frac{A-B}{a-b}[/tex]For the points (-6,7) and (4,-2), we have:
[tex]\begin{gathered} m=\frac{7--2}{-6-4} \\ =\frac{7+2}{-10} \\ =\frac{9}{-10} \\ \therefore m=-\frac{9}{10} \end{gathered}[/tex]The equation of a line in slope-intercept form, of a line with slope m and y-intercept b is:
[tex]y=mx+b[/tex]Substitute m=-9/10 and the coordinates of one point to find the y-intercept. Use, for instance, the point (-6,7):
[tex]\begin{gathered} 7=-\frac{9}{10}(-6)+b \\ \Rightarrow7=\frac{54}{10}+b \\ \Rightarrow b=7-\frac{54}{10} \\ \therefore b=\frac{8}{5} \end{gathered}[/tex]Substitute b=8/5 and m=-9/10 to find the equation of line Q:

Hello there. To solve this question, we have to remember some properties about conversion of values.
1. How many 2-liter bottles of soda will you need to fill ten 500 mililiter containers?
First, multiply the number of containers by its capacity, that is
[tex]10\cdot500=5000\text{ mililiters}[/tex]Notice that 1000 mililiters is equivalent to 1 liter, hence
[tex]5000\text{ mililiters }=5\text{ liters}[/tex]To fill these containers with 2-liter bottles of soda, you'll need at least 3 bottles.
The answer to the first question is 3.
2. How many mililiter are 1/5 liter?
Considering 1 liter = 1000 mililiters, we have that
[tex]\dfrac{1}{5}\text{ liter }=\dfrac{1}{5}\cdot1000\text{ mililiters }=200\text{ mililiter}[/tex]Hence the answer to this question is 2. 200

Wade and Ida are salespeople who earned the same amount this week, although Ida made 4 more sales than Wade. Wade earns a base of $153 plus $22 per sale. Ida earns a base of $17 plus $24 per sale. Write the equation for the number of sales Wade made this week
Answer:
y = 24x + 17 20
Step-by-step explanation:
Firstly, let's say that 153 and 17 are both the y-intercepts of their respective equations, while 22 and 24 are the slope. With this we can create the following set of equations:
y = 24x + 17
y = 22x + 153
So your answer would be y = 24x + 17
Now let's find the sales answer!
Since we know that Ida made 4 more sales than Wade this week, we could say:
y = 24(x+4) + 17
y = 22x + 153
Now since we know that they earned the same amount we can do the following:
24(x+4) + 17 = 22x + 153
Simplify...
24x + 96 + 17 = 22x + 153
Simplify again:
24x + 113 = 22x + 153
subtract 22x and 113 from both sides...
2x = 40
Then:
x = 20
So this means that Wade made 20 sales this week!
So let's check if we are right:
Now that we know that x = 20, we need to plug it into Wade's equation!
y = 22(20) + 153
y = 440 + 153
y = 593
Wade made $593 this week!
To check if we are right, let's plug it into Ida's equation:
y = 24x + 113
y = 24(20) + 113
y = 480 +113
y = 593
Ida also made $593 this week!
MEANING we are right!

the probability that the mean salary of the sample is less than $60,000 is? round 4 decimals if needed.
Answer:
0.26599
Step-by-step explanation:
We will assume a normal distribution for the salaries
We have the following information
Mean μ = 64000
Standard deviation σ = 6400
And we are asked to find P(X < 60000)
First find the z score corresponding to X = 60000
The z score is given by (X - μ) / σ
z score for 60000 with μ = 64000 and σ = 6400 is
z = (60000 - 64000)/6400
z = -40000/6400 = -0.625
We can either look up the P value from the z-tables or simply use a calculator
P(X < 60000) and this works out to 0.26599

Following the instructions provided, we shall use a graphing calculator (Desmos) to determine the equation of the circle shown by the "colorful people."
The first step is to determine the radius which we can observe from the circle itself, whose diameter spans from 0 units to 10 units along the x-axis. The radius therefore is 5 units (half of the diameter).
Observe also that the center has now moved away from the origin (0, 0), and if we move the slider very carefully for h, that would be 5 units away from the origin towards the right (along the x-axis), andk would be 7 units away from the origin) towards the bottom (along the y-axis).

Answer: .25x + 75.00 = C(x)
Step-by-step explanation:
without graphing, describe the transformation of each parabola or absolute value function y = 2 |x|+ 1
Remember the following transformations of a function:
[tex]c\cdot f(x)[/tex]This transformation stretches the function over the vertical axis if c>1 and shrinks it if 0
If c is positive, the orientation is mantained, and if c is negative, the function is also flipped over (it shrinks if -1
[tex]f(x)+c[/tex]This transformation moves the function vertically c units. It goes up if c>0 and down if c<0.
Therefore, starting with the absolute value function:
[tex]\lvert x\rvert[/tex]Multiply the function by 2:
[tex]2\cdot\lvert x\rvert[/tex]Since 2>1, then this is a vertical stretching by a factor of 2.
Next, add 1:
[tex]2\cdot\lvert x\rvert+1[/tex]This will translate the stretched absolute value function one unit upwards.
Therefore, the complete description of the transfromation would be:
[tex]y=2\cdot\lvert x\rvert+1[/tex]Is a vertical stretching of the absolute value function by a factor of 2, translated 1 unit upwards.
