Answer:

Option B and D are correct.

x = 3 and x = 10

Step-by-step explanation:

Given the functions:

f(x) =x^2-13x+30

Split the middle terms:

f(x) =x^2-10x-3x+30

Take out the common factor:

f(x) =x(x-10)-3(x-10)

⇒f(x) =(x-10)(x-3)

To find the zeroes of this function f(x).

Equate f(x) = 0

then;

(x-10)(x-3)=0

By zero product property: if ab=0 then a=0 or b = 0

then;

x-10 = 0 and x-3 = 0

⇒x = 10 and x = 3

Therefore, the zeros of the given function are: x = 10 and 3

The means and mean absolute deviations of sidney’s and phil’s grades are shown in the table below. means and mean absolute devia
DochEvi [55]

The expression that represents the ratio of the difference of the two means to Sidney’s mean absolute deviation is given by: Option B: 4/3.28

<h3>What is mean absolute deviation?</h3>

Mean absolute deviation is the average of the absolute deviation of each observation from their mean, for a considered set of observations.

For this case, the table of mean and mean absolute deviation is given as:

\begin{array}{ccc}&Mean&M.A.D.\\\text{Sidney}&82&3.28\\\text{Phill}&78&3.96\end{array}

(M.A.D refers to Mean Absolute Deviation).

So, difference in their mean is 82 - 78 = 4

Absolute deviation  for Sidney is 3.28

Thier ratio is: 4/3.28

Thus, the expression that represents the ratio of the difference of the two means to Sidney’s mean absolute deviation is given by: Option B: 4/3.28

Find the total cost for a $579 smartphone with 5% sales tax
tensa zangetsu [6.8K]
To find your answer first you must convert 5% into a decimal which will be 0.05. Then you will have to multiply 0.05 by 579 which will give you 28.95. The final step is to add $28. 95 which is the sales tax to $579 which will give you $550.05.
Final cost: $550.05

For all integers n, if n2 is odd, then n is odd. Use a proof by contraposition, as in Lemma 1.1. Let n be an integer. Suppose th
Reil [10]
Let's assume that the statement "if n^2 is odd, then is odd" is false. That would mean "n^2 is odd" leads to "n is even"

Suppose n is even. That means n = 2k where k is any integer.

Square both sides

n = 2k
n^2 = (2k)^2
n^2 = 4k^2
n^2 = 2*(2k^2)

The expression 2(2k^2) is in the form 2m where m is an integer (m = 2k^2) which shows us that n^2 is also even. 

So this contradicts the initial statement which forces n to be odd.
