I need help with this question. ​

Mathematics
1 answer:
Gnoma [55]3 years ago

Answer:

Step-by-step explanation:

P(female | junior)     *the | just means "given"*

In order to find this, you must know the formula:

P(A | B) = \frac{P(A and B)}{B}

So first, you have to find P(female and junior):

P(female and junior) = 6

Then, you just identify P(junior):

P(junior) = 2 + 6 = 8

Therefore, P(female | junior) = 6/8 (or 3/4), or 75%

Hope I helped!

(1 + i)/(1 + 2i)

To simplify this, we need to multiply both sides by the conjugate.

(1 + i)(1 - 2i)

1 - 2i - i - 3i^2

Combine like terms.

3i^2 - 3i + 1

i^2 = -1

-3i - 2 is the simplified numerator.

(1 + 2i)(1 - 2i)

1 - 2i + 2i - 4i^2

1 - 4i^2

i^2 = -2

1 + 4

5


<h3><u>The simplified expression is ((-3i)/5) + ((-2)/5)</u></h3>

bezimeni [28]

Answer:

$27,272.73= sales

Step-by-step explanation:

Giving the following information:

Desired commission= $900

Commission rate= 3.3% = 0.033 of sales

<u>To calculate the sales required, we need to use the following formula:</u>

Commission= sales*commission rate

900= sales*0.033

900/0.033= sales

$27,272.73= sales

Complete the slope-intercept form of the linear equation that represents the relationship in the table.
nevsk [136]

According to the given table, the slope-intercept equation of the line is given by:

y = -2x + 1

The equation of a line, in <em>slope-intercept</em> form, is given by:

y = mx + b

In which:

  • The slope is m.
  • The intercept is b.

In this problem, we are given two points, (3,-5) and (-2,5).

  • The slope is given by <u>change in y divided by change in x</u>, hence:

m = \frac{5 - (-5)}{-2 - 3} = -2

Hence:

y = -2x + b

Point (3,-5) means that when x = 3, y = -5, which is used to find b.

y = -2x + b

-5 = -2(3) + b

b = 1

Hence, the equation of the line is:

y = -2x + 1

What are the basics of linear equation​
denis23 [38]

Answer:

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of linear equation is y=mx + b.
