Answer:
x = 9
Number of observations = 6
Sum of observations = 54
Step-by-step explanation:
Number of observations, n = 6
Mean = ΣX / n
(6 + 8 + x + 2 + 10 + 2x - 1 + 2) / 6 = 9
(27 + 3x) / 6 = 9
27 + 3x = 6 * 9
27 + 3x = 54
3x = 54 - 27
3x = 27
x = 27 / 3
x = 9

Hello, I need help. thank you
Answer:
B
Step-by-step explanation:
all you need to do is add 5 to the y for example ( -5, 5) add 5 to the (x,5) to make ( -5,10). As you can see only the y value is shifting, not the x value, that's why you need to add 5 to all the y values.
So the answer here is B.
Answer:
B
Step-by-step explanation:
The answer is B because 5 units up from 5 is 10. A and B both have a y coordinate of 5 and the answer letter B is the only one that mention 10 as a y coordinate twice
Multiply the binomials:
(i) (2x + 5) and (4x-3)
Answer:
8x²+14x-15
Step-by-step explanation:
that the right answer
Answer:
8x² + 14x - 15
Step-by-step explanation:
(2x + 5)(4x - 3)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(4x - 3) + 5(4x - 3) ← distribute both parenthesis
= 8x² - 6x + 20x - 15 ← collect like terms
= 8x² + 14x - 15

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
a is a leg b is another leg c is the hypotenuseStep-by-step explanation:
Step 1: Identify
Leg a = 24
Leg b = 7 in
Leg c = x
Step 2: Solve for x
Substitute in variables [Pythagorean Theorem]: 24² + 7² = x²Evaluate exponents: 576 + 49 = x²Add: 625 = x²[Equality Property] Square root both sides: 25 = xRewrite/Rearrange: x = 25y is directly proportional to x.
when y=30, x=6
work out an equation connecting y and x
Answer:
y = 5x
Step-by-step explanation:
Use the direct variation equation y = kx
Plug in 30 as y and 6 as x, then solve for k
y = kx
30 = k(6)
5 = k
Plug in 5 as k into y = kx
y = 5x
So, the equation relating x and y is y = 5x
Answer:
y=5x
Step-by-step explanation:
30 divide by 6 = 5 so y = 5x

Bryce reads 18 pages in 1/3 of an hour. What is his rate in pages per hour?
Answer:
54 is the answer
Step-by-step explanation:
18 times 3
Answer: 54 pages per hour.
Step-by-step explanation:
If Bryce can read 18 pages in 1/3 of an hour, then we need to multiply 18 by 3 to find how many pages Bryce can read in 1 hour.
18 x 3 = 54.
In conclusion, Bryce can read 54 pages per hour.

Step-by-step explanation:
Write the equation of the line in slope-intercept form.
The equation of the line in slope-intercept form is
Answer:
y = -4/3 x + 2
Step-by-step explanation:
Let us assume the equation given is 3y + 4x = 6
The standard form in slope-intercept form is y = mx+c
m is the slope
c is the intercept
Make y the subject of the formula
3y + 4x = 6
3y = -4x + 6
Divide through by 3
3y/3 = -4/3 x + 6/3
y = -4/3 x + 2
Hence the equation of the line in slope-intercept form is y = -4/3 x + 2
x-4y=-4
5x – 4y= 12
Answer: {x,y} = {4,2}
[1] x - 4y = -4
[2] 5x - 4y = 12// Solve equation [1] for the variable x
[1] x = 4y - 4
// Plug this in for variable x in equation [2]
[2] 5•(4y-4) - 4y = 12
[2] 16y = 32
// Solve equation [2] for the variable y
[2] 16y = 32
[2] y = 2
// By now we know this much :
x = 4y-4
y = 2
// Use the y value to solve for x
x = 4(2)-4 = 4
Step-by-step explanation:
Answer: x=4 y=2

Which point is located in Quadrant IV?
Answer:
C is the answer
Step-by-step explanation:
Answer:
C. Quadrant IV = (8,-6)
Step-by-step explanation:
Q I = + +
Q II = - +
Q III = - -
Q IV = + -
(-8, 6) = II
(-8, -6) = III
(8, -6) = IV
(8, 6) = I
Quadrant IV = (8,-6)

What is the area of this quadrilateral?
8 ft
6 ft
3.ft
A. 33 square feet
B. 42 square feet
C. 17 square feet
D. 66 square feet
Answer:
a. 33 sqft
Step-by-step explanation:
The figure is made of two non-overlapping triangles, so the total area is the sum of the areas of the two triangles
Area of a triangle is 1/2(bh) where b = base length and h = height (b and h must be perpendicular to each other)
The top triangle has b = 6 and h=8, so A=1/2(6)(8) = 1/2(48) = 24
The bottom triangle has b=6 and h=3, so A=1/2(6)(3)=1/2(18) = 9
Total area is sum of these two or 24 + 9 = 33
Si colocan en 16 pisos, 16 ladrillos. ¿Cuántos ladrillos pusieron en total?. (expresarlo en forma de potencia)
Answer:
Númer total de ladrillos= 256
Step-by-step explanation:
Dada la siguiente información:
Total de pisos= 16
Total de ladrillos por piso= 16
Para calcular cantidad de ladrillos en total, tenemos que usar la siguiente formula:
Número total de ladrillos= total de ladrillos^2
Número total de ladrillos= 16^2
Númer total de ladrillos= 256
En este caso lo hace al cuadrado por que la cantidad de pisos y ladrillos por piso es la misma. Sino, es mejor expresarlo como una multiplicación.

Bath and $38,000 in student loans the interest rate on her salons is 8.25% per year she will be painless loans off for 20 years how much will Best pay altogether
Answer:
$100,700
Step-by-step explanation:
Given data
Principal= $38,000
rate= 8.25%
Time= 20 years
Applying the simple interest
A=P(1+rt)
substitute
A=38000(1+0.0825*20)
A=38000(1+1.65)
A=38000*(2.65)
A=$100,700
Hence in 20 years she will pay $100,700
