Answer:
97.35%
Step-by-step explanation:
Empirical rule formula states:
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .
From the question, we have the mean of :
Mean of 56 and a standard deviation of 10.
For 36
36 = μ - xσ
36 = 56 - 10x
56 - 36 = 10x
20 = 10x
x = 20/10
x = 2
Hence, the data falls within 2 standard deviation of the mean
Hence, since it is one side,
= 95%
= 47.5%
For 86
86 = μ - xσ
86 = 56 - 10x
56 - 86 = 10x
-30 = 10x
x = -30/10
x = -3
Hence, the data falls within 3 standard deviation of the mean
Hence, since it is 99.7% one side,
= 99.7%
= 49.85%
Hence, we add up
= 47.5% + 49.85%
= 97.35%
The approximate percentage of 1-mile long roadways with potholes numbering between 36 and 86 is 97.35%

Answer:
f = 2
Step-by-step explanation:
Hope this helps you! :3
Answer:
f = 2
Step-by-step explanation:
2+1.25f = 10 - 2.75f
Add 2.75f to both sides
2 + 4f = 10
Subtract 2 on both sides
4f = 8
Divide by 4 on both sides to isolate the variable f
f = 8/4
f = 2
solve for w and simplify the answer
Answer: w=20/3
Step-by-step explanation: start by multiplying -3/2 by 2 and multiply -10 by 2 as well. you would get -3w = -20. divide both sides by -3 and you’ll get 20/3.

If you have a square with a perimeter of 18 inches, what is the area of the square after
scaling it by 7? Round to the nearest tenth is needed.
Answer:
992.3 in^2 to the nearest tenth.
Step-by-step explanation:
The new perimeter will be 7*18 = 126 inches.
So the side of the new square will be 126/4 = 31.5 inches,
and it's area = 31,5^2
= 992.25

Find the amplitude, the EoA=y, the period, and the phase shift in terms of cosine for this graph.
Answer:
Step-by-step explanation:
or
Step-by-step explanation:
has:
1) amplitude=|a|
2) phase shift=b
3) period=2pi/c
d) vertical shift=d
--------------------------------------------------
You are given the amplitude is 2. This means a could either be 2 or -2.
You are given phase shift is -1/8. This means b is -1/8.
You are given the period is pi. So we need to solve pi=2pi/c.
pi=2pi/c
Dividing both sides by pi gives:
1=2/c
Multiply both sides by c gives:
c=2
The vertical shift is -2 so d=-2.
The equation could either be:
y=2cos(2(x-(-1/8)))-2
or
y=-2cos(2(x-(-1/8)))-2
Simplifying a little gives:
y=2cos(2x+1/4)-2
y=-2cos(2x+1/4)-2

Smith & Johnson produces a variety of men’s clothing. Their highest selling items are their fitted dress shirts. The profit earned from the sale of these shirts can be modeled by the expression -20x2+1,800x, where x is the price of one dress shirt. If p is the maximum profit earned from the sale of the dress shirts, write an equation that shows how the expression can be rewritten to model the price at which the shirts should be set in order to maximize profit.
Answer:
P=x(-x+90)Step-by-step explanation:
Step one:
given
Price
[tex]P= -20x^2+1800x[/tex]
where P is the maximum profit
x is the price of one shirt
Step two:
To rewrite the expression let us first divide through by 20
[tex]P= \frac{-20x^2}{20} +\frac{1800x }{20}\\\\P=-x^2+90x[/tex]
Factoring x out we have
[tex]P=-x^2+90x\\\\P=x(-x+90)[/tex]
Hence the rewritten expression equation for the price is
P=x(-x+90)

ellie is preheating her oven before using it to bake. the initial temperature of the oven is 65° and the temperature will increase the rate of 10° per minute after being turned on what is the temperature of the oven six minutes after being turned on what is the temperature of the oven t minutes after being turned on
Answer:
The temperature six minutes after being turned on is 125°.
T(t)= 65° + t * 10°
Step-by-step explanation:
Linear Equations
Ellie sets the temperature of the oven to 65°. The oven will increase the temperature at 10° per minute after being turned on.
After the first minute, the temperature of the oven is
65° + 10° = 75°
After the second minute, the temperature is:
65° + 2*10° = 65° + 20° = 85°
The same pattern goes on after minute 6, where the temperature is:
65° + 6*10° = 65° + 60° = 125°
The temperature six minutes after being turned on is 125°.
The general formula can be deducted for any time t as:
T(t)= 65° + t * 10°

Check all that apply.
O A. HL
B. SAS

D E. LA
F. SSS
Answer: HL, SAS, LL, SSS
Step-by-step explanation:
its that easy
ΔJKL and ΔQRS are congruent by HL, SAS, SSS, and LL postulates.
Options A, B, C, and F are the correct answer.
What is triangle congruency?
There are ways to prove that two triangles are congruent.
- Side-Side-Side (SSS) Congruence.
The three sides of one triangle are equal to the corresponding three sides of another triangle.
- Side-Angle-Side (SAS) Congruence.
The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.
- Angle-Side-Angle (ASA) Congruence.
The two angles and the included side of one triangle are equal to the corresponding two angles and included side of another triangle.
- Angle-Angle-Side (AAS) Congruence.
We have,
LL congruency
Two triangles are said to be congruent under LL congruence if they have two pairs of corresponding sides that are equal in length and the included angles between these pairs of sides are also equal.
HL congruency
If two right triangles have the same hypotenuse and one corresponding leg, then the two triangles are congruent (have the same shape and size).
Now,
The two triangles are right triangles.
So,
From the definition of congruency, we can say,
ΔJKL and ΔQRS are congruent by:
HL, SAS, SSS, and LL.
Thus,
ΔJKL and ΔQRS are congruent by HL, SAS, SSS, and LL postulates.

Answer:
-1 or f = 1.333333333 + 0.3333333333x
is what i got its not an answer so im sorry
Step-by-step explanation:
Simplifying
f(6) = 2x + 8
Reorder the terms for easier multiplication:
6f = 2x + 8
Reorder the terms:
6f = 8 + 2x
Solving
6f = 8 + 2x
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by '6'.
f = 1.333333333 + 0.3333333333x
Simplifying
f = 1.333333333 + 0.3333333333x

The sum of two consecutive integers is two more than the third integer. Find the integers
Answer:
3, 4, 5Step-by-step explanation:
x - the first integer
x+1 - the next integer consecutive to x (the second consecutive integer)
x + x+1 - the sum of two consecutive integers
x+1+1=x+2 - the integer consecutive to x+1 (the third consecutive integer)
x+2 + 2 - two more than the third integer
x + x+1 = x+2 + 2
2x + 1 = x + 4
x + 1 = 4
x = 3
x+1 = 3+1 = 4
x+2 = 3+2 = 5

Someone plz help. I added a screenshot shot below
Answer:
Juan's Plan
y = .25x+12.95
where y is cost and x is minutes
Tiffany's Plan
y = .15x+14.95
where y is cost and x is minutes
...
Set the cost equal and find where x is the same for both.
.25x+12.95 = .15x+14.95
Group x variables to one side of the equation
.25x + 12.95 - 12.95 - .15x = .15x - .15x + 14.95 - 12.95
.25x - .15x = 14.95 - 12.95
.1x = 2
x=20 minutes
