Answer:

5/4 or 1 & 1/4

Step-by-step explanation:

Since you have to find the total time spent on dancing, you must add.

Since both fractions have different denominators it would be best if you convert one of them until they're the same.

In this case 1/2 can be changed into 2/4

2/4 + 3/4 = 5/4

Which would be 1 & 1/4

The daily earnings of an employee who works on a commission basis are given by the following probability distribution. Find the
elena-s [515]

Answer: The employee's expected earnings is 78.5.

Step-by-step explanation:

Since we have given that

$   Probability

0         0.07

25       0.12

50       0.17

75       0.14

100     0.28

125      0.18

150     0.04

We need to find the employee's expected earnings.

As we know the formula for "Expectation":

E(x)=0\times 0.07+25\times 0.12+50\times 0.17+75\times 0.14+100\times 0.28+125\times 0.18+150\times 0.04\\\\E(x)=0+3+8.5+10.5+28+22.5+6\\\\E(x)=78.5

Hence, the employee's expected earnings is 78.5.

Plz help me with this
Nana76 [90]
This question is not even trying to test your arithmetic.  It's just testing
to see whether you know how to read numbers in words properly.

When you read numbers in words, the only time you ever say "and"
is for a decimal point.  There are no decimals in this question, so the
"and" is not a part of any numbers.

The question gives you two numbers. The word "and" is the marker
that's BETWEEN them.  The two numbers are 1,300 and 950 .

The first thing the question wants you to do is write the numerical
expression for all the words.  That's    (1300 - 950) / 4 .

The next thing you're supposed to do is"evaluate the expression" ...
find out what number it all boils down to.  I don't think you'll have
any trouble with that now.
