Step-by-step explanation:

"The probability of drawing a red ace followed by another ace of any color without replacement."

There are 4 aces total, 2 of which are red. After the first red ace is drawn, there will be 3 aces left. So the probability is:

P = (2/52) (3/51)

P = 1/442

"The probability of drawing a king followed by a queen with replacement."

There are 4 kings and 4 queens. So the probability is:

P = (4/52) (4/52)

P = 1/169

"The probability of drawing a 3 or a 5 followed by a 4 or a 6 with replacement."

There are 8 cards that are either 3 or 5, and 8 cards that are either 4 or 6. So the probability is:

P = (8/52) (8/52)

P = 4/169

"The probability of drawing a spade followed by a jack of any color with replacement."

There are 13 spades, and 4 jacks. So the probability is:

P = (13/52) (4/52)

P = 1/52

Answer: 2 1/3 cubic inches

Step-by-step explanation:

Perhaps you want to know the volume of the prism in cubic inches.

Find the total volume of the smaller cubes:

63(1/3 in)^3 = 63/27 in^3 = 7/3 in^3 = 2 1/3 in^3

7. The bottom of a river makes a V-shape that can be modeled with the absolute value function,

hjlf

Answer:

If one buoy is placed 120 feet away from the left shore, then the distance of the second buoy from the left shore = 480

Step-by-step explanation:

Given that:

The absolute value function:

$d(h) = \dfrac{1}{6}|h - 300| - 50$

To calculate the position of the buoy where the river bottom is 20 feet below the surface, we equate the absolute value function to the negative value of 20 feet and then solve it for h.

d(h) = -20

$d(h) = \dfrac{1}{6}|h - 300| - 50 = -20$

Let us add the sum of 50 on both sides, then:

$= \dfrac{1}{6}|h - 300| - 50+50 = -20+50$

$= \dfrac{1}{6}|h - 300| = 30$

By multiplying 6 on both sides, we have:

|h - 300| = 30 (6)

|h - 300| = 180

We can attempt the above expression by rewriting it as two equations:

h - 300 = 180 or h - 300 = - 180

Let us add 300 to both sides from the two expressions above:

h - 300 + 300 = 180 + 300 or h - 300 + 300 = -180 + 300

h = 480 or h = 120

Thus, if one buoy is placed 120 feet away from the left shore, then the distance of the second buoy from the left shore = 480

Identify the level of measurement of the data, and explain what is wrong with the given calculation. In a survey, the favorite

Trava [24]

Answer:

The data are at the <u>Nominal</u> level of measurement.

The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement.

Step-by-step explanation:

The objective here is to Identify the level of measurement of the data, and explain what is wrong with the given calculation.

The data are at the <u> Nominal </u> level of measurement due to the fact that it portrays the qualitative levels of naming and representing different hierarchies from 100 basketball, 200 basketball, 300 football, 400 anything else

b) We are being informed that, the average (mean) is calculated for 597 respondents and the result is 256.1.

The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement. At nominal level this type of data set do not measure at all , it is not significant to compute their average (mean).
