Answer:
6^10
Step-by-step explanation:
6^2 * 6^11
-----------------
6^3
First simplify the numerator. We know a^b*a^c = a^(b+c)
6^(2+11)
-----------------
6^3
6^(13)
-----------------
6^3
Then a^b / a^c = a^(b-c)
6^(13-3) = 6^10
Answer:
6^10
Step-by-step explanation:
To solve this you need to remember 2 things.
First off, multipication is addition with exponents.
And secondly, division is subtraction with expoinents.
So on the top we have 6^2*6^11
So this is really 6^11+2
=
6^13
Now we need to divide by 6^3:
6^13/6^3
And this would tecnically be:
6^13-3
=
6^10
So the expression 6^10 is your answer.

What is the equation of the line that has a slope of -2 and passes through the point (-1, 2)?
Answer:
[tex]{ \bf{y = mx + c}} \\ 2 = ( - 2 \times - 1) + c \\ c = 0 \\ \\ { \boxed{ \bf{y = - 2x}}}[/tex]
Answer:
y = -2x
Step-by-step explanation:
The equation of a line in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -2x +b
Using the point
2 = -2(-1)+b
2 = 2+b
Add -2 to each side
2-2 =b
0=b
y = -2x+0
y = -2x
-2(5x+8)=14+6x step by step
Answer:
x=-15/8
Step-by-step explanation:
Hi there!
We're given the equation -2(5x+8)=14+6x and we need to find the value of x
we do this by isolating the variable so that x is on one side, and everything else is on the other
First, we need to do the distributive property on the left, as the -2 is factored out of 5x+8 and it makes solving for x harder
-2(5x+8)=14+6x
multiply both 5x and 8 by -2
-10x-16=14+6x
add 16 to both sides to clear it from the left side (-16+16=0)
-10x-16=14+6x
+16 +16
_____________
-10x=30+6x
subtract 6x from both sides (6x-6x=0)
-10x=30+6x
-6x -6x
_____________
-16x=30
now, we do have x by itself, but we have -16 attached to it; we need the value of 1x, or x without any coefficient in the front of it
divide both sides by -16
x=30/-16
simplify (divide both sides by -2)
x=-15/8
we can leave it as an improper fraction
Hope this helps! :)
Answer:
x = 15 / 8
Step-by-step explanation:
−2(5x+8) = 14 + 6x
Simplify both sides of the equation.
−2(5x+8) = 14 +6x
(−2)(5x) + (−2)(8) = 14 +6x (Distribute)
−10x +−16 = 14 +6x
−10x −16 = 6x +14
Subtract 6x from both sides.
−10x −16 −6x = 6x + 14 −6x
−16x −16 = 14
Add 16 to both sides.
−16x −16 +16 = 14 + 16
−16x=30
Divide both sides by -16.
-16 x / - 16 = 30/-16
Simplify ( divide RHS side by - 2 )
x = 15 / 8

Suppose a normal distribution has a mean of 48 abd a standard deviation of 5. What is the probability that a data value is between 48 and 52?
Answer:
P(48<x<52) = 0.2881
Step-by-step explanation:
P(48<x<52) = normalcdf(lower,upper,µ,σ) = normalcdf(48,52,48,5) ≈ 0.2881
Therefore, the probability that a data value is between 48 and 52 is 0.2881, or about a 28.81% chance of occurrence.

What is the gradient of the blue line?
The slope or gradient of the blue line from the given graph is -3.3.
The equation of line is shown in the graph.
What is slope or gradient of a line?The slope or gradient of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope or gradient = Rise/Run
From the given graph, the gradient of a line is
Slope = rise/run
= -4/1.2
= -3.3

4n + 2 = 6 (1/3n-2/3)
N=???
l give brainiest
Answer:
N= -3
Step-by-step explanation:
4n+2 = 6(1/3n - 2/3)
4n+2 = 2n - 4
2n +2 = -4
2n = -6
n = -3
Answer:
- 3
Step-by-step explanation:
4n + 2 = 6 ( 1 / 3 n - 2 / 3 )
Divide 2 on both sides,
2n + 1 = 3 ( 1 / 3 n - 2 / 3 )
2n + 1 = 3n / 3 - 6 /3
2n + 1 = n - 2
2n - n = - 2 - 1
n = - 3

Please help with this
Step-by-step explanation:
multiply 455 by 0.20
convert percentage to decimal
20% = 0.20 ( multiply by 10^-2)
why does this work?
convert to a fraction
20/100 ( this is also how you get decimal)
simplify 20/100 = 1/5
so multiplying 455 by 0.20 is the same as dividing by 5

At Barlow School,4/9 of the 873 students are boys. Add to Willow school, 2/3 of the 630 students are girls. Which school has the greater number of boys and by how many?
Answer:
Barlow School has more boys. It has 178 more boys than Willow School.
Step-by-step explanation:
[tex] \frac{4 \times 873}{9} = \frac{3492}{9} = 388[/tex]
Barlow School has 388 boys.
[tex] \frac{630 \times 2}{3} = \frac{1260}{3} = 420[/tex]
There are 420 girls in Willow School. To find the number of boys, subtract the number of students with the number of girls.
630 - 420 = 210
Willow School has 210 boys
388 - 210 = 178
Barlow School has 178 more boys than Willow School
