Answer:

Median

Step-by-step explanation:

There is an outlier (115) that would pull the average up, and there is no mode, so median is the best in this case.

Answer:

Average or Median is the best measurement because Median would show the in between of his high's and low's but average shows, well, average

State the commutative property of multiplication, and provide an example using two different numbers.

attashe74 [19]

Answer:

The commutative property of multiplication states that the numbers of the operation can change their order, and this action will not alter the outcome.

Example 1:

$8*4=32$

Changing the order of the numbers in the operation:

$4*8=32\\\\Then,\\8*4=4*8$

Example 2:

$10*12=120$

Changing the order of the numbers in the operation:

$12*10=120\\\\Then,\\10*12=12*10$

A diver was swimming 62 feet below sea level. He then dove 39 feet further down. He ascended 48 feet after a while. Find the new

Harman [31]

Answer:

53 feet

Step-by-step explanation:

if you start with 62 feet and add 39 feet because he went down 62+39 you get 101 then if you subtract 48 because he went up, 101-48 you get 53 feet

A vase contains 7 red flowers, 3 white flowers, and 5 yellow flowers. If George selects a flower from the vase for his wife, wha

gtnhenbr [62]

Answer:

The answer to your question is: P(A) = 0.47

Step-by-step explanation:

Data

7 red flowers

3 white flowers

5 yellow flowers

Probability that he select a red one

Formula

P(A) = Number of favorable cases of A / total number of outcomes

Number of favorable cases = 7

Total number of outcomes = 7 + 3 + 5 = 15

Substitution

P(A) = 7 / 15

P(A) = 0.47

A. 77.4

Step-by-step explanation:

Linear approximation formula

$L(x)=f(a)+f'(a)(x-a)$

Given function:

$f(x)=(x+1)^2$

$\boxed{\begin{minipage}{5.4 cm}\underline{Chain Rule for Differentiation}\\\\If $y=f(u)$ and $u=g(x)$ then:\\\\$\dfrac{\text{d}y}{\text{d}x}=\dfrac{\text{d}y}{\text{d}u}\times \dfrac{\text{d}u}{\text{d}x}$\\\end{minipage}}$

$\boxed{\begin{minipage}{5 cm}\underline{Differentiating $x^n$}\\\\If $y=x^n$, then $\dfrac{\text{d}y}{\text{d}x}=xn^{n-1}$\\\end{minipage}}$

$\boxed{\begin{minipage}{4 cm}\underline{Differentiating $ax$}\\\\If $y=ax$, then $\dfrac{\text{d}y}{\text{d}x}=a$\\\end{minipage}}$

Use the chain rule to differentiate the function.

$\textsf{Let }\:y=u^2\:\textsf{ where }u=(x+1)$

Differentiate the two parts separately:

$y=u^2 \implies \dfrac{\text{d}y}{\text{d}u}=2u$

$u=x+1 \implies \dfrac{\text{d}u}{\text{d}x}=1$

Put everything back into the chain rule formula:

$\begin{aligned} \implies \dfrac{\text{d}y}{\text{d}x} & =2u \times 1\\ & = 2u \\ & = 2(x+1)\\ & = 2x+2 \end{aligned}$

$\textsf{Therefore, }\:f'(x)=2x+2.$ .

The linear approximation at a = 8 is:

$\begin{aligned}L(x) & =f(a)+f'(a)(x-a)\\\\\implies L(x) & = f(8)+f'(8)(x-8)\\& = (8+1)^2+(2(8)+2)(x-8)\\& = 81+18(x-8)\\& = 18x-63\end{aligned}$

Finally, substitute x = 7.8 into the linear approximation equation:

$\begin{aligned}\implies L(7.8) & =18(7.8)-63\\& = 140.4-63\\& = 77.4\end{aligned}$
