Answer:
You can increase by 100% and more of the price in something but you can never decrease more than 100% of something.
Step-by-step explanation:
If you have something that costs 8 dollars to begin with then all of the sudden it costs 20 dollars, it increased by 150%. 8 is 100$ of 8, 4 is 50% of 8. 8+4=12. 12+8=20. The price began at 8 then increased by itself plus half of it which is 12.
IF you decrease the price by 150% it'll be -20 dollars. You cant physically have negative amount of money.

Step-by-step explanation:
The mean is 30.
The standard deviation is 5
The data point 37 is more than one standard deviation from the mean.
What is a bell curve?
'A bell curve is the informal name of a graph that depicts a normal probability distribution. The bell curve is perfectly symmetrical. It is concentrated around the peak and decreases on either side. In a bell curve, the peak represents the most probable event in the dataset while the other events are equally distributed around the peak. The peak of the curve corresponds to the mean of the dataset.'
According to the given problem,
Since, the curve of the bell curve peaks at the mean, therefore, in the given bell curve, the curve peaks at 30.
The standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean. In the given bell curve, the points lie at a distance of 5. Therefore the standard deviation is 5.
The data point 37 is more than one standard deviation from the mean.
Since, the standard deviation is 5,
Mean = 30
Next Data Point = ( 30 + 5 )
= 35
Therefore the data point 37 is more than one standard deviation from the mean.
Hence, we can conclude, the bell curve has a mean of 30, standard deviation of 5 with the data point 37 being more than one standard deviation from the mean.

Write the order pair that represents YZ. Then find the magnitude of YZ. Y(5,4), Z (0,-3)
Answer:
Ordered pair of YZ is (-5,-7) and magnitude of YZ is 8.602
Step-by-step explanation:
Given data:
Two pairs Y (5,4) and Z (0, -3)
To find: ordered pair of YZ
YZ = Z - Y = (0-5, -3-4)
= (-5, -7)
Hence ordered pair of YZ is (-5,-7)
To find: magnitude of YZ.
Here Y and Z are initial and final points of vector. Magnitude of YZ is distance between points Y and Z. Distance formula is
Distance = [tex]\sqrt{(x2-x1)^{2} + (y2-y1)^{2} }[/tex]
magnitude of YZ = [tex]\sqrt{(0-5)^{2} + (-3-4)^{2} }[/tex]
= [tex]\sqrt{74}[/tex]
= 8.602
Another method:
magnitude of YZ = |YZ|
|YZ| = [tex]\sqrt{(-5)^{2} + (-7)^{2} }[/tex] ...............(since |xy| = [tex]\sqrt{(x)^{2} + (y)^{2} }[/tex]
= [tex]\sqrt{74}[/tex]
= 8.602

Answer:
x = 6
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Answer:
x = { 3, -2 }
Step-by-step explanation:
Let's actually find the solutions to | X+10 | = 3x - 2. Because of the absolute value operator this breaks down into two simpler problems:
1) x + 10 = 3x - 2, or 12 = 4x. Then x = 3
2) -(x + 10) = 3x - 2, or -x - 10 = 3x - 2, or -8 = 4x. Then x = -2

Select one
The signup fee at Jon's Gym is $100 more than the signup fee at Bella's Gym
Jon's Gym charges $15 more per month Bella's Gym
The signup fee at Jon's Gym is $15 more than the signup fee at Bella's Gym
Jon's Gym charges $100 more per month than Bella's Gym.
Answer: The signup fee at Jon's Gym is $100 more than the signup fee at Bella's Gym
Step-by-step explanation:
Hi, to answer this question we have to write an equation for the cost of Bella's Gym
Jon's Gym: f(x) = 30x + 150
Bella's Gym has a signup fee of $50 and charges $45 dollars per month.
So, we have to multiply the number of months (x) by the cost per month, and add the signup fee cost (50).
Bella's Gym: f(x) = 45x+ 50
Since Jon's signup fee is 150 and Bella's signup fee is 50 , the difference of both costs is 100 (150-50=100), and since Jon's gym has the more expensive fee:
The signup fee at Jon's Gym is $100 more than the signup fee at Bella's Gym
Final answer:
The statement that the signup fee at Jon's Gym is $100 more than the signup fee at Bella's Gym is true.
Jon's Gym charges $30 per month while Bella's Gym charges $45 per month; thus, Jon's Gym charges $15 less, not more.
Explanation:
Comparing the costs of gym memberships at Jon's Gym and Bella's Gym requires analysis of the initial signup fees and the monthly rates. The function for Jon's Gym, f(x) = 30x + 150, indicates a signup fee of $150 and a monthly rate of $30. Bella's Gym has a signup fee of $50 and a monthly rate of $45. To determine the true statement, we compare these numbers directly:
The signup fee at Jon's Gym is $100 more than the signup fee at Bella's Gym ($150 - $50 = $100).The other statements provided in the question can be dismissed as false:
Jon's Gym does not charge $15 more per month than Bella's Gym; it charges $15 less per month.The signup fee at Jon's Gym is not $15 more than the signup fee at Bella's Gym; it is $100 more.Jon's Gym does not charge $100 more per month than Bella's Gym.Therefore, the correct statement is that The signup fee at Jon's Gym is $100 more than the signup fee at Bella's Gym.

What is the domain of y = csc(x)?
The domain of y = cosec(x) includes all real numbers except for the integer multiples of [tex]\pi[/tex], where the sine function equals zero and the cosecant function is undefined.
The domain of a function is the set of all possible input values (usually x values) for which the function is defined. In the case of y = cosec(x), the cosecant function is the reciprocal of the sine function, meaning cosec(x) = 1/sin(x). Since the sine of an angle can be zero and division by zero is undefined, the domain of y = cosec(x) must exclude any x values where sin(x) = 0.
The sine function is zero at integer multiples of [tex]\pi[/tex], so the domain of cosec(x) is all real numbers except for integer multiples of [tex]\pi[/tex]

If Pam works more than 40 hours per week, her hourly wage for every hour over 40 is 1.5 times her normal hourly wage of $7. Write a piecewise-defined function that gives Pam's weekly pay P(h) in terms of the number of hours h that she works.
Answer:
Sorry I made a mistake here is a picture of the answer. I hope this helps.
Pam's weekly pay can be modeled using a piecewise function. If Pam works 40 hours or less, her pay is her hourly rate times her hours worked. However, if she works more than 40 hours, her pay is her standard pay for 40 hours plus 1.5 times her hourly rate for each hour beyond 40.
Explanation:Pam's weekly pay, P(h), can be defined piecewise, meaning we split up h (the total hours she works) into different 'pieces' based on the terms of her pay structure. In this case, the 40 hour standard work week serves as the dividing line between these pieces. The piecewise function could be represented as follows:
P(h) = { $7h, if h <= 40
$7*40 + $7*1.5*(h-40), if h > 40 }
In this function, when Pam works 40 hours or fewer (h <= 40), her pay is simply her hourly wage ($7) times the number of hours worked. However, if she works more than 40 hours (h > 40), her pay is her standard weekly pay for the first 40 hours ($7 times 40) plus 1.5 times her hourly wage for each hour beyond 40 hours.

Which equation can be used to find the length of side x?
The equation that can be used to find the length of side x is:
cos(25°) = x / 32.
The equation that can be used to find the length of side x is:
cos(25°) = x / 32
This equation is based on the trigonometric ratio tan, which is defined as
the opposite side over the adjacent side.
In this case, the opposite side is x and the adjacent side is 32.
We know the angle between these two sides is 25°, so we can use the
tan function to solve for x.
x = cos(25°) * 32
x = 14.65 cm
Therefore, the equation that can be used to find the length of side x is:
cos(25°) = x / 32
