Answer: x=9
Step-by-step explanation:
x-(-6)=15
first the subtraction sign and the negative sign becomes a plus sign
x+6=15
-6 -6
Next you subtract 6 from both sides of the equation. And that leaves you with

What you want to do at the beginning is to "Keep-Change-Flip" the fractions. You're going to keep the first fraction the same, change the divide sign to a multiply sign, and flip the second fraction.
Next, you'll have to factor, and then you can cancel out common components.

5,356+2,398
=(5,356+2)+ (2,398 + 2)
5,358+2400=7,758
is kElly's answer correct? what mistake did she make?
Answer:
No because she added 2 instead of 2398. She thought the 2 was separate because of the comma separating the 2 thousand. She also made a mistake by thinking she could add easily by adding 2 to 2398 to make 2400.
The addition of the given numbers is 7,758.
Use the concept of addition defined as:
In mathematics, addition is an arithmetic operation that combines two or more numbers to produce a sum.
It is a fundamental operation used to calculate the total or the result of combining quantities. When adding numbers, you start with the first number, and then incrementally add subsequent numbers to obtain a final sum. The order in which numbers are added does not affect the result, thanks to the commutative property of addition.
This fundamental concept of addition forms the basis for more advanced mathematical operations and problem-solving techniques.
The given numbers are:
5,356+2,398
Now simply add these numbers:
5 3 5 6
+2 3 9 8
7 7 5 4
Hence,
The addition of the given numbers is 7,758.

The average ticket price for a Spring Training baseball game is $32.61, with a standard deviation of $8.62. In a random sample of 40 Spring Training tickets, find the probability that the mean ticket price exceeds $35. (Round your answer to three decimal places)
Using the normal probability distribution and the central limit theorem, it is found that there is a 0.04 = 4% probability that the mean ticket price exceeds $35.
------------------------------------------
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
------------------------------------------
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
------------------------------------------
The average ticket price for a Spring Training baseball game is $32.61, with a standard deviation of $8.62.
This means that [tex]\mu = 32.61, \sigma = 8.62[/tex]
------------------------------------------
Sample of 40:
This means that [tex]n = 40, s = \frac{8.62}{\sqrt{40}}[/tex]
------------------------------------------
In a random sample of 40 Spring Training tickets, find the probability that the mean ticket price exceeds $35.
This is 1 subtracted by the p-value of Z when X = 35, so:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{35 - 32.61}{\frac{8.62}{\sqrt{40}}}[/tex]
[tex]Z = 1.754[/tex]
[tex]Z = 1.754[/tex] has a p-value of 0.96.
1 - 0.96 = 0.04
0.04 = 4% probability that the mean ticket price exceeds $35.

remember questions like "if 1 apple costs $1.10, how much are 2 apples or 5 or 10 apples ?"
you remember what you had to do ?
pretty common sense : you multiplied the price by the same number that you multiplied the unit count number with. so, in my example, by 2, by 5 and by 10. and you got $2.20, $5.50 and $11.00 as prices.
so, what do you think we need to do to calculate the miles that are residents by 2 cm on the map ?
right ! we need to multiply by 2 - because 2×1 = 2.
so, 4.5 × 2 = 9 miles
yes, if 1 cm on the map stands for 4.5 actual miles, then 2 cm stand for 2×4.5 = 9 actual miles.

the graph of f(X)=sin(x) is transformed to a new function g(x) by straching it vertically by a factor of 2 and shifting it 3 units up. What is the equation of the new function g(x)?
9514 1404 393
Answer:
g(x) = 2sin(x) +3
Step-by-step explanation:
The transformation g(x) = c·f(x) +k represents a vertical scaling by a factor of c and a vertical shift by k units. You want the scale factor to be 2 and the vertical shift to be +3, so the transformed function is ...
g(x) = 2f(x) +3
g(x) = 2sin(x) +3

The length of a rectangle is 2 cm more than 5
times the width. The perimeter is 196 cm. Find
the width and length.
length = 82 cm
width = 16 cm
Step-by-step explanation:
x = length
y = width
the perimeter of a rectangle is the lengths of all sides added together. so, 2×length plus 2× width
x = 5y + 2
196 = 2x + 2y
let's use the first equation as substitute in the second equation.
196 = 2×(5y + 2) + 2y = 10y + 4 + 2y = 12y + 4
12y = 192
y = 16 cm
x = 5y + 2 = 5×16 + 2 = 80 + 2 = 82 cm

• (-1, -8)
An ordered pair is simply the x-coordinate and the y-coordinate of a point.
The ordered pair of the bullseye is (4,-2.5)
From the given image (see attachment), we have:
[tex](x_1,y_1) = (9,3)[/tex]
[tex](x_2,y_2) = (-1,-8)[/tex]
The bullseye is at the midpoint of these two points.
So, the ordered pair of the bullseye is calculated using the following midpoint formula.
[tex](x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
So, we have:
[tex](x,y) = (\frac{9-1}{2},\frac{3-8}{2})[/tex]
[tex](x,y) = (\frac{8}{2},\frac{-5}{2})[/tex]
[tex](x,y) = (4,-2.5)[/tex]
Hence, the ordered pair of the bullseye is (4,-2.5)

Answer:
(3,4)
Step-by-step explanation:
Find the equation of BH. (x+3)/(9/11+3)=(y-1)/(4/11-1)
(x+3)/(42/11)= (y-1)/(-7/11)
(x+3)*11/42= (y-1)*11/-7
x+3= -6(y-1)
x+3=-6y+6
y=-1/6x+1/2
m1=-1/6
AC: y=m2x+b
m1*m2=-1 (for perpendicular lines)
-1/6m2=-1
m2=6
-2=6*2+b
b=-14
y=6x-14
Find CH
(x-2)/(9/11-2)= (y+2)/(4/11+2)
(x-2)/(-13/11)= (y+2)/26/11
(x-2)*-11/13=(y+2)*11/26
(x-2)(-2)=y+2
-2x+4=y+2
y=-2x+2
m3=-2
AB: y=m4x+b
m3*m4=-1
-2*m4=-1
m4=0.5
Take the point B from AB
1=-3*0.5+b
b=2.5
y=0.5x+2.5
A is the point of intersection of two linesAB and AC
We have simultaneous equations
y=6x-14
y=0.5x+2.5
6x-14=0.5x+2.5
5.5x=16.5
x=3
y=6*3-14=4
