The probability is 56/100, or 14/25 = 0.56.

These events are not mutually exclusive, meaning they can happen at the same time.  This means we use

P(A or B) = P(A) + P(B) - P(A and B)

P(carpool or full time) = P(carpool) + P(full time) - P(carpool & full time)

There are 6+9=15 people out of 100 that carpool.
There are 7+4+30+6=47 people out of 100 that work full time.
There are 6 people out of 100 that carpool and work full time.

This gives us
15/100 + 47/100 - 6/100 = 56/100

This is the graph of y = sin(x). Does anyone know the second part?
Alborosie

Answer:

The resulting graph is y = 5\cdot \sin x.

Step-by-step explanation:

The resulting function is of the form:

y = A\cdot \sin x + k

Where:

x - Independent variable, dimensionless.

y - Dependent variable, dimensionless.

A - Amplitude, dimensionless.

k - Midpoint value, dimensionless.

The sine function is bounded, between -1 and 1, and must be multiplied by a stretch factor. That is: A > 0. According to the graph, the function is bounded between 5 (y_{max}) and -5 (y_{min}), and the midpoint value (k) is 0. The amplitude is determined by the following calculation:

A = \frac{y_{max}-y_{min}}{2}

If y_{min} = -5 and y_{max} = 5, then:

A = 5

The resulting graph is y = 5\cdot \sin x.

What is the approximate square root of 12 to the nearest integer
Licemer1 [7]

Answer:

3

Step-by-step explanation:

3² =  9, so  √9 = 3

4² = 16, so √16 = 4.

12 is closer to 9 than to 16, so √12 is closer to √9 than to √16.

√12 ≈ 3 (to the closest integer)

12.93 is what percent of 172.40?
Maurinko [17]

Answer:

<h2>7.5%</h2>

Step-by-step explanation:

METHOD\ 1:\\\\\begin{array}{ccc}172.4&-&100\%\\12.93&-&p\%\end{array}\qquad\text{cross multiply}\\\\172.4p=(12.93)(100)\\\\172.4p=1293\qquad\text{divide both sides by 172.4}\\\\p=7.5\ (\%)

METHOD\ 2:\\\\\dfrac{12.93}{172.4}\cdot100\%=\dfrac{1293}{17240}\cdot100\%=0.075\cdot100\%=7.5\%
