cassie is training for a marathon. she has been recording her miles in a journal leading up to race day. the following table shows some of her results. on sunday, cassie didn't run any miles. what could be a possible cause for this outlier
Answer:
There is an outlier because she was injured and could not run.
Step-by-step explanation:
There are several reasons why Cassie wouldn't have been able to run on Sunday, but a potential reason is because she had a minor injury that took her one day to heal. Because of her taking this day off, it creates an outlier in our table.

Answer:
7953.873
Step-by-step explanation:
The first derivative is ...
f'(x) = 4·3x²·e^x +4x³·e^x = e^x(4x³ +12x²)
Then the second derivative is ...
f''(x) = (12x² +24x)e^x +(4x³ +12x²)e^x
f''(x) = e^x(4x³ +24x² +24x)
So, f''(3) = (e^3)(4·27 +24·9 +24·3) = 396e^3 = 7953.87262158
Rounded to thousandths, this is ...
f''(3) = 7953.873
Answer:
f''(x) ≈ 7953.87

Which expressions are equivalent to √-27?
Answer:
the first one and that's the only one
[tex]3i\sqrt{3} \ \text{ and } \ i\sqrt{27}[/tex]
===================================================
Work Shown:
We will use the rule that sqrt(A*B) = sqrt(A)*sqrt(B) to get the following
[tex]x = \sqrt{-27}\\\\x = \sqrt{-1*27}\\\\x = \sqrt{-1}*\sqrt{27}\\\\x = i\sqrt{27} \ \text{ ... one answer; choice D}\\\\x = i\sqrt{9*3}\\\\x = i\sqrt{9}*\sqrt{3}\\\\x = i*3*\sqrt{3}\\\\x = 3i\sqrt{3} \ \text{ ... another answer; choice A}\\\\[/tex]
While choices C and D seem to look equivalent, note how the 'i' is under the square root in choice C. The 'i' term must be outside the root to be equivalent to the original expression. We denote [tex]i=\sqrt{-1}[/tex]

19. Brian bought a new jacket at a discount of 30%. If the original price was $65, how much did Brian pay for the jacket?
Answer:45.5
Step-by-step explanation:
65•30%=19.5
65-19.5=45.5
Cost of the jacket with the discount is given by the equation A = $ 45.50
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of the jacket with the discount be A
Now , the equation will be
The cost of the jacket = $ 65
The discount percentage =30 %
So , the discount amount = ( 30/100 ) x 65
The discount amount = 0.3 x 65
The discount amount = $ 19.50
Now , the cost of the jacket with the discount A = cost of the jacket - discount amount
Substituting the values in the equation , we get
The cost of the jacket with the discount A = 65 - 19.50
The cost of the jacket with the discount A = $ 45.50
Hence , the cost is $ 45.50

A triangle has a base of 16" in height of 1/8 inch what is the area?
Answer:
Area of triangle is 1 inches²
Step-by-step explanation:
We are given:
Base of triangle = 16 inches
Height of triangle = [tex]\frac{1}{8} \:[/tex] inches
We need to find:
Area of triangle
The formula used to find Area of triangle is:
[tex]Area \:of\: triangle=\frac{1}{2}\times b \times h[/tex]
where b is base and h is height.
Putting values and finding area:
[tex]Area \:of\: triangle=\frac{1}{2}\times 16 \times \frac{1}{8}\\ Area \:of\: triangle=\frac{16}{16}\\ Area \:of\: triangle=1\:inches^2[/tex]
So, Area of triangle is 1 inches²

Jim is 9 years older than June. Alex is 8 years younger than June. If the total of
their ages is 82, how old is the eldest of them?
Answer:
36 years old (jim)
Step-by-step explanation:
looks like a good ol' word problem!
first, if you don't know what to do, always assign variables
Jim's age: x+9
June's age: x
Alex's age: x-8
we know the sum of their ages which is 82
so, x+9+x+x-8=82
simplify
3x+1=82
3x=81
x=27, but we're not done yet
Now we know x
jim: 36
june: 27
Alex: 21
so the oldest is jim at 36
what percent of one us dollar is $.25
Answer:
25%
Step-by-step explanation:
25/100 = 25%
The percentage value of $0.25 in one dollar is 25%.
Given data:
The initial amount is represented as $0.25.
The value of one dollar is $1.
To determine what percent $.25 is of one US dollar, divide $.25 by $1 and then multiply by 100 to express it as a percentage.
($.25 / $1) * 100 = 0.25 * 100
0.25 * 100 = 25 %
So, the value is 25 %.
Hence, $.25 is 25% of one US dollar.
