Answer:

35.6t = d

Step-by-step explanation:

71.2 hours every 2 hours

Divide by 2 hours to find how far the bird travels in a single hour:

71.2 / 2 = 35.6

The bird travels 35.6 km every hour.

So given a number d, t is 35.6 times that number.

35.6t = d

The graph below represents a polynomial.
AleksAgata [21]

Answer:

C

Step-by-step explanation:

The polynomial on the graph has zeros or x-intercepts at x = -3, 0, 2, 4. These come from the factors x (x+3)(x-2)(x-4). Notice at 4 it doesn't cross but just touches. This means it has a degree of 2. So the factors are x(x+3)(x-2)(x-4)^2. This matches to C.

What are these fractions in simplest form?
Anton [14]
\frac{16y^{3}}{20y^{4}} =  \frac{4}{5y}
\frac{6xy}{16y} =  \frac{3x}{8}
\frac{abc}{10abc} =  \frac{1}{10}
\frac{mn^{2}}{pm^{5}n} =  \frac{n}{pm^{4}}
\frac{12h^{3}k}{16h^{2}k^{2}} =  \frac{3h}{4k}
\frac{8x}{10y} =  \frac{4x}{5y}
\frac{24n^{2}}{28n} =  \frac{6n}{7}
\frac{30hxy}{54kxy}  =  \frac{5h}{9k}
\frac{5jh}{15jh^{3}} =  \frac{1}{3h^{2}}
\frac{20s^{2}t^{3}}{16st^{5}} =  \frac{5s}{4t^{2}}

An investment firm offers three types of equity investments,
Fudgin [204]

Answer:

<u>The expected value of the total return rate for the firm's clients is C. 7.4%</u>

Step-by-step explanation:

1. Let's review all the information given for solving the question:

Type of equity investments = A, B and C

Percentage of investment in each type of equity = 30% in A, 50% in B and 20% in C.

Rates of return of each type of equity investment = 10% for A, 6% for B and 7% for C.

2. Let's find the expected value of the total return rate for the investment firm:

Return rate for each type of investment = Percentage of investment * Rate of return

For A = 30% * 10% = 0.3 * 0.1  = 0.03

For B = 50% * 6% = 0.5 * 0.06 = 0.03

For C = 20% * 7% = 0.2 * 0.07 = 0.014

Total return rate = Return rate for A + Return rate for B + Return rate for C

Total return rate = 0.03 + 0.03 + 0.014 = 0.074

<u>Total return rate = 0.074 * 100 = 7.4%</u>

<u>The expected value of the total return rate for the firm's clients is C. 7.4%</u>

Snezhnost [94]
The table below summarises the calculation for the standard deviation of x-bar.

\begin{tabular}&#10;{|c|c|c|c|}&#10;Drawing (x)&$\bar{x}$&$x-\bar{x}$&$(x-\bar{x})^2\\[1ex]&#10;2,2,2&2&-2.5&6.25\\&#10;2,2,3&2.3&-2.2&4.84\\&#10;2,2,5&3&-1.5&2.25\\&#10;2,2,8&4&-0.5&0.25\\&#10;2,3,3&2.7&-1.8&3.24\\&#10;2,3,5&3.3&-1.2&1.44\\&#10;2,3,8&4.3&-0.2&0.04\\&#10;2,5,5&4&-0.5&0.25\\&#10;2,5,8&5&0.5&0.25\\&#10;2,8,8&6&1.5&2.25\\&#10;3,3,3&3&-1.5&2.25\\&#10;3,3,5&3.7&-0.8&0.64\\&#10;3,3,8&4.7&0.2&0.04\\&#10;3,5,5&4.3&-0.2&0.04\\&#10;3,5,8&5.3&0.8&0.64\\&#10;3,8,8&6.3&1.8&3.24\\&#10;5,5,5&5&0.5&0.25\\&#10;5,5,8&6&1.5&2.25\\&#10;5,8,8&7&2.5&6.25\\&#10;8,8,8&8&3.5&12.25\\&#10;\end{tabular}

\sum\bar{x}=89.9 \\  \\ \bar{\bar{x}}= \frac{\sum\bar{x}}{n}=\frac{89.9}{20} \approx4.5 \\  \\ \sum(x-\bar{x})^2=30.41 \\  \\ s.d= \sqrt{ \frac{\sum(x-\bar{x})^2}{n} } = \sqrt{ \frac{30.41}{20} } = \sqrt{1.5205} =1.23

Therefore, the standard deviation of x-bar is approximately 1.23.
