Answer:

A) Independent

B) Dependent

Step-by-step explanation:

A) If we take a marble out and put the marble back, it means we have restored the sample to what it was initially and thus it doesn't affect probability of making another selection.

Thus, this is an independent event.

B) A card is taken from a deck of cards without replacement and set aside. Then after that another card is taken from the first sample, this means that the first sample size has now reduced and thus the first card taken affects the probability of the second card to be picked. Thus, this is a dependent event.

A 6 inch personal pizza has 650 calories, with 240 of those from fat. A 14 inch pizza is cut into 8 slices. Estimate the number

professor190 [17]

Answer:

Number of calories in one slice of a 14 inch pizza is 189.825. 

Step-by-step explanation:

Given that 6 inch pizza has 650 calories. 

Therefore 1 inch pizza has $\frac{650}{6}$ calories. 

14 inch pizza will have

$\frac{650}{6} \times 14=216.67 \times 14=1516.66 \ calories$

Given that the 14 inch pizza is divided into 8 slices.

Therefore each slice of the 14 inch pizza will have

 $\frac {1516.66}{8} =189.825 calories$

Express cos(27pi/8) as a trigonometric function of an angle in Quadrant I.

Kryger [21]

Answer:

The equivalent trigonometric ratio in Quadrant I is $-\cos (\frac{3\pi}{8})$

Step-by-step explanation:

The terminal side of $\frac{27\pi}{8}$ is in the 3rd quadrant.

The principal angle is $\frac{3\pi}{8}$

In other words, the terminal side of $\frac{27\pi}{8}$ makes an acute angle of $\frac{3\pi}{8}$ radian with the positive x-axis. Acute angles are in the first quadrant.

Since the cosine ratio is negative in the 3rd quadrant,

$\cos (\frac{27\pi}{8})=-\cos (\frac{3\pi}{8})$
