Answer:
15
Step-by-step explanation:
Let's solve your equation step-by-step.
15+8x=45+6x
Step 1: Simplify both sides of the equation.
8x+15=6x+45
Step 2: Subtract 6x from both sides.
8x+15−6x=6x+45−6x
2x+15=45
Step 3: Subtract 15 from both sides.
2x+15−15=45−15
2x=30
Step 4: Divide both sides by 2.
2x

Step-by-step explanation:
The number of people using an older version of a spreadsheet program decreases at a rate that is proportional at any time to the number of people still using the version at that time.
There were 10{,}00010,00010, comma, 000 people using the older version of the spreadsheet program when the new version first came out. The number of people still using the older version decreases by 20\%20%20, percent every 666 months.
Answer:
The decrease in the use of older version is given by,[tex]y = 10000 \cdot0.60^{t}[/tex].
Step-by-step explanation:
It is provided that the number of people using an older version of a spreadsheet program decreases at a rate that is proportional at any time to the number of people still using the version at that time.
The exponential decay function is given as follows:
[tex]y=a(1-r)^{t}[/tex]
Here,
y = final value
a = initial value
r = decay rate
t = time taken
It is provided that there were 10,000 people using the older version of the spreadsheet program when the new version first came out. And the number of people still using the older version decreases by 20% every 6 months.
So, every half-yearly the decrease in the number of people using the older version is 20%. This implies for a year the decay rate is 40%.
Then the decrease in the use of older version is given as follows:
[tex]y=10000(1-0.40)^{t}\\\\y=10000\cdot 0.60^{t}[/tex]

A coin has heads on one side and tails on the other the coin is tossed 12 times and lands heads up four times which best describes what happens when the number of trials increases significantly
Answer:
The number of occurrences for both possible events(heads or tails) will be closer to the expected outcome. By that I mean that of all the total outcomes heads will be about half of them and so will tails.

20 POINTS! The following graph shows the amount of money Jonah earns when he babysits for the family who lives next door. Based on the graph, which of the following statements are true? Select ALL that apply.
When Jonah babysits one hour, he earns $7.50.
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
The number of hours Jonah works depends on how much he earns.
Answer:
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
Step-by-step explanation:
When Jonah babysits one hour, he earns $7.50.
looking at the graph we see at 1 hour he earns 4 dollars false
The equation e = 4 h can be used to describe this situation.
The slope is 4 so y = 4x e = 4h would also work true
Jonah earns $20 to babysit for 5 hours.
Using our equation from above
e = 4*5 = 20 true
The number of hours Jonah works depends on how much he earns.
This would be false
The dependent variable is on the y axis. The amount he earns depends on how much he works

Step-by-step explanation:
The price of a Honda Civic is $26,750. You can finance this by paying $3500 down and $455 per month for 60 months. Determine the total finance charge. A. $3500 B. 3750 C. $4050 D. $5200
Answer:
Step-by-step explanation:
455 per month for 60 months = 60 * 455 = 27,300
Plus amount of down payment = 27,300 + 3,500 = 30,800
Finance charge = 30,800-26,750 = 4,050

Results of a blood test are normally distributed with a mean of 6.2 and a standard deviation of 1.5. What is the probability that a patient has a blood test result less than or equal to 8.3?
Answer:
91.92%
Step-by-step explanation:
Given that:
Mean (μ) = 6.2, standard deviation (σ) = 1.5
Z score is a measure in statistics to determine the relationship of a measured value with the mean. It is given by the equation:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
To calculate the probability that a patient has a blood test result less than or equal to 8.3, we need to calculate the z score of 8.3
For x = 8.3, the z score is:
[tex]z=\frac{x-\mu}{\sigma}=\frac{8.3-6.2}{1.5} =1.4[/tex]
From the probability distribution table:
P( x ≤ 8.3) = P(z < 1.4) = 0.9192 = 91.92%

Answer: b = 2a/h
Step-by-step explanation:
a = bh/2
multiply each side by 2
2a = bh
divide each side by h
2a/h = b
Answer:
b = 2a/h
The area of a triangle is related to the base and height of the triangle by the formula a = bh/2
Which of the following could be the equation of the function below?
On a coordinate plane, a curve crosses the y-axis at y = negative 1.5. It has a maximum at negative 1.5 and a minimum at negative 2.5. It goes through 2 cycles at pi.
y = 0.5 cosine (2 (x minus StartFraction pi Over 2 EndFraction)) + 2
y = 0.5 cosine (4 (x minus StartFraction pi Over 2 EndFraction)) minus 2
y = 0.5 cosine (4 (x + pi)) + 2
y = 0.5 cosine (2 (x minus pi)) minus 2
Answer:
y = 0.5 cosine (4 (x - pi/2)) - 2
Step-by-step explanation:
Taking the general form:
y = A cosine (Bx - Cπ)) + D
In the following case. the constants are:
y = 0.5 cosine (4x - 2π)) - 2
A: 0.5
B: 4
C: 2π
D: -2
The range of this function is:
range = [-|A|+D, |A|+D]
range = [-0.5-2, 0.5-2]
range = [-2.5, -1.5]
Which coincides with "It has a maximum at negative 1.5 and a minimum at negative 2.5"
At x = 0, the function value is:
y = 0.5 cosine (4(0) - 2π)) - 2
y = 0.5 - 2 = -1.5
As indicated in "a curve crosses the y-axis at y = negative 1.5"
The period of the function is:
period: 2π/B
period = 2π/4 = π/2 or 2 cycles at π
as described in "It goes through 2 cycles at pi."
Answer:
B) y = 0.5 cosine (4 (x minus StartFraction pi Over 2 EndFraction)) minus 2

Write the equation of the line in slope intercept form y=mx + b that would have the slope of two and crosses through the ordered pair (-3,5).
Answer:
y=2x+11
Step-by-step explanation:
Slope is 2
y=2x+b
plug in (-3,5)
5=-6+b
b=11
y=2x+11
Answer:
y = 2x+11
Step-by-step explanation:
y = mx+b where m is the slope and b is the y intercept
We know the slope is 2
y =2x+b
We have a point (-3,5)
Substitute this into the equation
5 = 2(-3)+b
5 = -6+b
Add 6 to each side
5+6 = b
11 =b
The equation is
y = 2x+11

The density of oxygen is 0.001332 gram per cubic meter. Represent 0.001332 in scientific notation.
Answer:
1.332 × 10-3
Step-by-step explanation:
you move the decimal point to the right until there's only one digit on the left side of it. the exponent is 3 because that's the number of places you moved the decimal point, and it's negative because you moved it to the right. if you move the decimal to the left it is positive, to the right is negative :)
By basic calculation We can represent 0.001332 in scientific notation as [tex]1.332\times 10^{-3}[/tex]
What is scientific notation?Scientific notation is a way of expressing numbers big numbers in short form with approximate values.
Given number is 0.001332
we can write 0.001332 as
