For Domain, you just need to watch out for Square Roots and/or Fractions! 1) a POLYNOMIAL (no square roots or fractions), i.e. f(x) = x^2 + 3x + 1, domain is "all real numbers." 2) a FRACTION (w/ no square root), i.e. f(x) = (2x+1)/(x^2+5x+6). Set bottom "not equal" to zero.

Answer:

D 133 degrees

Step-by-step explanation:

The measure of an angle external to a circle = the difference of the two arcs intercepted divided by 2

47 = [ (360 - x) - x ] / 2

94 = 360 - 2x

x = 133 degrees of the arc

Answer:

The probability is 2/7 or 28.57%

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

Let

x------> size of the event space

y-----> size of the sample space

$P=\frac{x}{y}$

In this problem we have

$x=4$ ---> number of peanuts

$y=2+4+3+5=14$ ---> total number of items

substitute

$P=\frac{4}{14}$

Simplify

$P=\frac{2}{7}=0.2857$

Convert to percentage

$0.2857*100=28.57\%$
