A normal distribution (X) has a mean of 100 and a standard deviation of 10.
What is the x value that is the third quartile for this distribution?
Round your answer to the first decimal position.
The x value for the third quartile for this distribution is 106.8
Z score
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
where μ is the mean, x = raw score and σ is the standard deviation.
Given μ = 100, σ = 10.
The third quartile correspond with a z score of 0.675, hence:
0.675 = (x - 100) / 10
x = 106.8
The x value for the third quartile for this distribution is 106.8

Hi! Let me help you!
Perpendicular lines have slopes that are opposite reciprocals.This means we take a number, flop it over, and change its sign.In this case, we have a line with a slope of [tex]\displaystyle-\frac{1}{3}[/tex]Flop it over:[tex]\rm{-3}[/tex]Change its sign:3Thus, the slope of the line perpendicular to the given line is 3.Now, what is its equation?Since we know the slope and a point that the line intersects, we can write the line's equation in Point-Slope Form:y-y1=m(x-x1)Where y1 is the y-coordinate of the point, m is the slope, and x1 is the x-coordinate.In this case, y1=2, m=3, and x1=4.Plug in the values:y-2=3(x-4)y-2=3x-12y=3x-12+2y=3x-10Answer:

Answer:
Step 1) P = 600, Decimal format: 0.04, Balance = 624
Step 2) Principle = 624, Balance = 648.96
Step 3) Principle = 648.96, Balance = 674.92
Step-by-step explanation:
Use the formula of A = P(1 + r/n)^n*t
P = 600, r = 4%, n = 1, t = 1 years.
Plug in
A = 600(1 + 0.04/1)^1*1
A = 600 * 1.04^1
A = 600 * 1.04
A = 624
To find the seperate interest
A = P + I
624 = 600 + I
I = 624 - 600
I = 24
Repeat for Step 2
P = 624, r = 4%, n = 1, t = 1
A = 624(1 + 0.04/1)^1*1
A = 624 * 1.04^1
A = 624 * 1.04
A = 648.96
Repeat for interest
648.96 = 624 + I
I = 648.96 - 624
I = 24.96
Repeat for step 3
A = 648.96, r = 4%, n = 1, t = 1
A = 648.96(1 + 0.04/1)^1*1
A = 648.96 * 1.04^1
A = 648.96 * 1.04
A = 674.92
Interest repeat
674.92 = 648.96 + I
I = 674.92 - 648.96
I = 25.96

table?
0
1
2
3
-2
(0,-6)
(3,0)
(-6,0)
(0,3)
Answer:
-6
Step-by-step explanation:
x-intercept is y = 0, so the point is (-6, 0), answer is -6
The Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the function f(x).
What is Intercept?The term "intercept" refers to the location where a line or curve crosses a graph's axis. The x-intercept is the point at which the x-axis is crossed. The y-intercept is the point at which the y-axis is crossed.
The x- or y-axis intersection point is what is meant when a line has an intercept. The y-axis is often taken into account if the axis is not stated. The letter "b" is typically used to represent it.
We know that the x intercept can be find where the value of y=0
So, From the table attached,
For x = -1, f(-1) = 0
For x = 2, f(2) = 0
For x = 3, f(3) = 0
Thus, Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the function f(x).

-3,2 and 8,2 in slope intercept form
Answer:
y = 2
Step-by-step explanation:
So we need to find the slope first.
m = y_2 - y_1/x_2 - x_1
Substitute
m = 2 - (2)/8 - (-3)
Simplify now.
Multiply -1 by 2
m = 2 - 2/(8 - (-3)
2 from 2
m = 0/8 - (-3)
Now we need to simplify the denominator.
To do so lets multiply -1 by -3
m = 0/8 + 3
m = 0/11
m = 0
Now we have the slope of 0 and the given point of (-3, 2)
So y - (2) = 0 * (x - (-3)) (Formula > y - y_1 = m(x - x_1) this comes from the original slope equation]
Simplify further
y - 2 = 0 * (x + 3)
Now we solve for y
Multiply 0 by x + 3
y - 2 = 0
Add 2 to both sides
y = 2

I THINK!!!!!! (x, y) = (-4, -25) im not completely sure tho
Step-by-step explanation:
substitute y = 7x + 3 in equation 2
9x - 2y = 14
9x - 2(7x + 3) = 14
9x - 14x + 6 = 14
-5x + 6 = 14
-5x = 14 - 6
x = 8 ÷ 5
x = 1.6
subs x = 1.6 into equation 1
y = 7x + 3
y = 7(1.6) + 3
y = 11.2 + 3
y = 14.2
thus, x = 1.6, y = 14.2
Suppose you have invested $1500 at an APR of 8%. Use the Rule of 72 to estimate how long it will be until your investment reaches $3000.
Answer:
25 Years. thank you for your question
The time required for the investment of $1500 reaches $3000 with APR of 8% using the rule of 72 is 9 years.
What is the Rule of 72?The rule of 72 is the easy way to calculate the number of years required the investment with the given interest rate. It can be calculated as,
[tex]t\approx\dfrac{72}{r}[/tex]
Here, (t) is the time period and (r) is the rate of return.
The invested amount is $1500 and the value of APR is 8%. The time we have to calculate using the rule of 72.
The final amount of the investment is $3000 which is double the initial amount. Thus, the time period required to double the investment with 8% of interest is,
[tex]t\approx\dfrac{72}{8}\\t\approx9[/tex]
Thus, the time required for the investment of $1500 reaches $3000 with APR of 8% using the rule of 72 is 9 years.

a person spends rs.1500 in buying goods;if each kg had cost rs.25 more he would have got 5 kg less .what weight did he buy?
Answer:
12kg
Step-by-step explanation:
the total money is =1500
each kg =25
so, we first multiply 25 as each kg by 5kg. To have the kg remaining
25×5 = 125
then
1500÷125
=12kg

Find the equation of the line passing through the point (2,-4) that is parallel to the line y=3x+2
Answer:
y=3x-10
Step-by-step explanation:
When you have to find a parallel line, you take the slope of the other line, so we already know y=3x+b. Then, plug in 2 and -4 as your x and y values and you get -4=3(2)+b. Then solve 3×2=6, so -4=6+b, subtract 6 from both sides, -10=b.
