Answer:

<h2>$42000</h2>

Step-by-step explanation:

step one:

Given that the initial salary is  $40,000

each year and the expected pay rise is $2000 each year

step two:

We can calculate her expected earnings at the end of the year to be

= salary +expected pay rise

=$40000+$2000

= $42000

<h2>Hence at the end of the year, she will earn a total of  $42000</h2>

Answer:

0.26 and 0.577

Step-by-step explanation:

Given :

x :___0 ___ 1 ____ 2 ____ 3

f(x):_0.80 _0.15__0.04 __0.01

The mean :

E(X) = Σ(x * p(x))

E(X) = (0*0.8) + (1*0.15) + (2*0.04) + (3*0.01)

E(X) = 0 + 0.15 + 0.08 + 0.03

E(X) = 0.26

Var(X) = Σx²*p(x)) - E(x)²

Σx²*p(x)) = (0^2*0.8) + (1^2*0.15) + (2^2*0.04) + (3^2*0.01) = 0.4

Σx²*p(x)) - E(x)² = 0.4 - 0.26² = 0.3324

Std(X) = √0.334 = 0.577

Answer:

a. 0.69

b. 0.13

c.0.56

Step-by-step explanation:

Total number = 100

a) either means students with either option are valid

69/100 = 0.69

b) both means each student has done both math and english

=13/100 = 0.13

c) Only one means has done one subject and not both classes. We have 23 for math and 33 for english (this is according to your venn diagram)

23+33=56

one subject =56/100 = 0.56

list the angles of triangle DEF in order from smallest to largest measure if DE equals 7 EF equals 9 and DF equals 3
Alex787 [66]
When you illustrate the problem, an image like that shown in the picture is formed. You are asked to order the angles in increasing order. Since, it did not ask for the values, we don't have to solve it.

Note that the larger the angle, the larger its opening, thus its opposite side would be larger also. Using this analogy and referring to the picture, the order of angles should be: Angle E < Angle F < Angle D
