Answer:

100% = 30. There are 30 students in Mr.Fulton's class

Step-by-step explanation:

If we have 12 as 40%, we divide it by 2 to get the base value which is 6=20%.

Now we multiply the base by 5 so 20% x 5= 100% and 6 x 5 equals 30. so 100% = 30

A DVD box set includes 3 thriller movies and 2 comidies. Use t to represent the cost of each thriller and c to represent the cos
suter [353]

Answer:

The expression representing the Total cost of 6 boxes is 6(3t + 2c).

The Simplified expression representing the Total cost of 6 boxes is 18t + 12c.

Step-by-step explanation:

Given:

Number of thriller movies = 3

Number of Comedy movies = 2

Let the cost of thriller movie be t

Also Let the cost of comedy movie be c

Total Number of boxes = 6

Now, given a DVD box set includes 3 thriller movies and 2 comedies.

Cost of Each box = 3t + 2c

We need to find the total cost of 6 boxes

Total Cost of 6 boxes is = 6(3t + 2c)

Hence the expression representing the Total cost of 6 boxes is 6(3t + 2c).

Simplifying the above expression we get;

Total Cost of 6 boxes is = 6(3t + 2c)= 6\times3t+6\times2c=18t+12c

Hence the Simplified expression representing the Total cost of 6 boxes is 18t + 12c.

a. Suppose a BMW dealer in Fullerton, CA is trying to calculate the probability of his car sale for next week. The dealer knows
egoroff_w [7]

Answer:

0.45576

Step-by-step explanation:

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

Standard Deviation = √variance

Mean = 50

= √9

= 3

z = 51 - 50/3

= 0.11111

Probability value from Z-Table:

P(x<51) = 0.54424

P(x>51) = 1 - P(x<51)

= 1 - 0.54424

= 0.45576

The probability that the dealer will sell 51 or more cars is 0.45576

If X is a random variable denoting number of defective items, which discrete probability distribution is appropriate
Lesechka [4]

Considering that for each item, there are only two possible outcomes, and the probability of an item being defective is independent of any other item, the binomial distribution is appropriate.

<h3>What is the binomial probability distribution?</h3>

It is the probability of <u>exactly x successes on n repeated trials, with p probability</u> of a success on each trial.

How to do this and whats the answer
Vinvika [58]

Answer:

(b) 36 degrees.

Step-by-step explanation:

K is the center of the circle so triangle KMN is isosceles and m < KMN = m KNM =  26 degrees ( base angles are equal)

So m <  LMK = m <LMN - m < KMN

= 98 - 26

= 72 degrees.

Now triangle LKM is also isosceles since K is the center of the circle so

m <  LKM = 180 - 2* 72

= 180 - 144

= 36 degrees.
