Answer: 0.66

Step-by-step explanation:

He must choose 2 courses.

The options are:

one of two science classes

one of three social sciences classes.

For the first class selection we do not have any restriction, so that selection can be ignored.

Now, we can assume that one of the 3 social sciences is economics, so we have 2 classes that are not economics.

Then, the probability that he does not select economics (if the selections are at random) is equal to the number of classes that are not economics divided the total number of classes:

p = 2/3 = 0.66

A business has $11,080 to spend on new laptops and tablet computers for its salespeople. The laptops cost $515 each. The tablets
Fynjy0 [20]
Let x be the number of new laptops and y be the number of tablets that the company should buy. The equations that best show the given conditions are as follows,
                                   x + y = 30
                                515x + 285y = 11080
Solving simultaneously for the values of x and y gives an answer of x = 11 and y = 19.

Thus, the business should buy 11 laptops and 19 tablets.

What is the first term of the sequence below? ___1, 5,25,125
gtnhenbr [62]

Answer:

The first term of the sequence is 1/5

Step-by-step explanation:

The first term is 1/5.

The reason is that there is a common ratio between each term. In this case multiplying the previous term in the sequence by 5 would give the next term.

So in this case 1/5 is the first term.

If we multiply 1/5 by 5, it will give the next term which is 1.

1/5*5=1

Thus the first term in the sequence = 1/5....
