Answer: Unlikely

Step-by-step explanation:

Given: The probability of choosing a penny from the 1980s from the bag of pennies without looking=\frac{3}{40}=0.075

We know that the probability of any event lies between 0 and 1.

  • If probability of occurring event is 0 then the event is impossible.
  • If probability of occurring any event is 1 then the event certain.
  • If probability of occurring any event lies between 0.5 and 1 then the event is said to be likely.
  • If probability of occurring any event lies between 0 and 0.5 then the event is said to be unlikely.

Since, 0.075 lieas between 0 and 0.5, therefore the event is said to be unlikely.

What is the length of segment BC. ( ) units
weqwewe [10]

Answer:

BC = 144 units

Step-by-step explanation:

It is given a line segment BC.

D is the point on the line segment.

<u>To find the length of BC</u>

BC = 8x

CD = 3x + 8  and BD = 4x + 10

BC = CD + BD

8x = 3x + 8 + 4x + 10

8x = 7x + 18

x = 18

BC = 8x = 8 * 18 = 144 units

Therefore the length of segment BC = 144 units

Alona [7]

Answer: B

Step-by-step explanation: To obtain the mean for a general set of data, the formula used is;

= (sum of all the data set)/ (number of data set)

The number of data set for the two samples is 10

For the mean for the security company;

= (1.6+1.8+1.6+1.8+1.7+1.2+1.1+1.2+1.2+1.5)/10 = 14.7/10

= $ 1.47million

For the mean for the other companies;

= (1.5+2.1+1.9+2.2+1.9+1.7+2.1+2.2+2.2+1.8)/10 =19.6/10

= $ 1.96 million

The data from the samples have to be rearranged before the median can be obtained;

For the Security Company;

1.1 1.2 1.2 1.2 1.5 1.6 1.6 1.7 1.8 1.8

There are two data sets in the middle, therefore the median will be obtained by finding the average of the data sets;

= (1.5+1.6)/2 =$ 1.55 million

For the other companies;

1.5 1.7 1.8 1.9 1.9 2.1 2.1 2.2 2.2 2.2

There are two data sets in the middle, therefore the median will be obtained by finding the average of the data sets;

= (1.9+2.1)/2 = $ 2.00 million

Therefore, the answer is B
