Answer:

angle 2 = 128 because of a rule that I unfortunately cannot remember the name of....

angle 6 = 180 - 47 = 133

because a straight line = 180 degrees

angle 3 = 180 - 128 = 52

Same reason as angle 6

angle 1 = 52 + 47 = 99

180 - 99 = 81

Sum of the angles in a triangle = 180

The zeros of a function are the values of for which the function is equal to zero. Enter a number in each blank to make true statements about the function ()=(2−6)(−4).

Answers

Answer:

Here we want to complete the blank to make the equality true:

( ) = (2 - 6)*(-4)

The equality is true if we have the same value in both sides, so we can think of this as an algebraic equation:

x = (2 - 6)*(-4)

We just need to find the value of x.

Then let's solve the right side:

x = (2 - 6)*(-4) = (-4)*(-4)

Remember the rule of signs:

(-)*(-) = (+)

x = (-4)*(-4) = 4*4 = 16

Then we need to complete the blank with the number 16

(16) = (2 - 6)*(-4)

Describe the trend/correlation
shown in the scatter plot below

Answers

Answer:

Negative correlation.

Step-by-step explanation:

Negative correlation means that as x increases, y decreases

Positive correlation means that as x increases, y also increases.

No correlation means that neither of the two above cases happens.

In the graph, we can see that on the right (when x is negative) the general y values are larger.

As x increases, the y-values decrease.

(Particularly, we could adjust these data with a linear equation with a negative slope)

Then this is a negative correlation.

[tex]\sqrt{625}[/tex] = 25

Step-by-step explanation:

This question is pretty easy. All you need to do is use the pythagorean theorem. A^2+B^2=C^2

(20)^2+(15)^2=C^2

400+225=C^2

625=C^2

To get the C alone you need to do the opposite of squaring something which is taking the square root of something.

So, this means that the answer is C=25

x = 45

Step-by-step explanation:

The angles are supplementary

(2x + 40) + (3x - 85) = 180

Combine like terms

5x - 45 = 180

Add 45 to both sides

5x = 225

Divide both sides by 5

Jean wants to invest a gift of $4,250 in the stock market. A broker suggests two companies, Solar Solutions (SOLR) and Frontline Medical (FLMD). He provides the probabilities for an annual return on $4,250 based on their historical gains: SOLR: 50% chance of $1,000 gain, 35% chance of $200 gain, 15% chance of $600 loss FLMD: 80% chance of $750 gain, 20% chance of $100 loss Which is the best analysis of these investments?​

Answers

Answer:

the answer is the question with $580 in it please correct me if im wrong

Step-by-step explanation:

Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

How to calculate the expected return?

The expected return on SOLR is calculated by multiplying the probability of each outcome by the amount of the gain or loss, and then adding these results:

50% chance of $1,000 gain: 0.5 x $1,000 = $500

35% chance of $200 gain: 0.35 x $200 = $70

15% chance of $600 loss: 0.15 x -$600 = -$90

Therefore, the expected return on SOLR is $500 + $70 - $90 = $480.

The expected return on FLMD is calculated in the same way:

80% chance of $750 gain: 0.8 x $750 = $600

20% chance of $100 loss: 0.2 x -$100 = -$20

Therefore, the expected return on FLMD is $600 - $20 = $580.

Since the expected return on FLMD is higher than the expected return on SOLR, FLMD is the better investment.

The expected return on FLMD is $580, which means that Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

Find the value of k

Answers

Answer:

k = 3.9

Step-by-step explanation:

Since the three possible outcomes are given. Therefore, the sum of all the probabilities of the three possible outcomes will be equal to one:

[tex]\frac{7}{13} +\frac{1}{k}+ \frac{1}{2k} = 1 \\\\\frac{1}{k} \frac{1}{2k} =1-\frac{7}{13}\\\\\frac{3}{2k} \frac{5}{13}\\\\2k = \frac{(13)(3)}{5}\\\\k = \frac{39}{(5)(2)}\\[/tex]
