Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given that

m=-1    (m is slope)point (2, 4)      

NOW LET US SOLVE THE BLANKS

Point (2, 4) means the x-value is: x=2, and y-value is: y=4

so

y = __4__     ,      m = __-1__      ,    and     x = __2__

y=mx+b

_4_ = -1 (__2__)+b

_4_ = _-2_ + b

_6_ = b

The y-intercept is _6_.

The equation of line is y = _-1_ x + _6_

The grams of sugar per serving for three brands of cereal are 4 g, 10 g, and 14 g. The probability of choosing a cereal with 4 grams of sugar is 1/4 . The probability of choosing a cereal with 10 grams of sugar is 5/8 . The probability of choosing a cereal with 14 grams of sugar is 1/8 .

What is the expected value of the number of grams of sugar in cereal?

Answers

Answer:

[tex]Expected\ Value = 9[/tex]

Step-by-step explanation:

Given

Cereal A

[tex]Probability = \frac{1}{4}[/tex]

[tex]Grams = 4[/tex]

Cereal B

[tex]Probability = \frac{5}{8}[/tex]

[tex]Grams = 10[/tex]

Cereal C

[tex]Probability = \frac{1}{8}[/tex]

[tex]Grams = 14[/tex]

Required

Determine the expected value of grams of sugar

This is calculated by multiplying the probability and grams of sugar in each cereal.

The results of the products are then added together

i.e.

[tex]Expected\ Value = \frac{1}{4} * 4 + \frac{5}{8} * 10 + \frac{1}{8} * 14[/tex]

[tex]Expected\ Value = 1 + \frac{50}{8}+ \frac{14}{8}[/tex]

[tex]Expected\ Value = 1 + 6.25 + 1.75[/tex]

[tex]Expected\ Value = 9[/tex]

Hence;

The expected value of grams of sugar is 9 grams

Answers

Answer:

  48°

Step-by-step explanation:

Supplementary angles total 180°.

  m∠A +m∠B = 180°

  (6x -30)° +(8x +28)° = 180°

  14x = 182 . . . . . . . . . . . . . . . . divide by ° and add 2

  x = 13 . . . . . . . . . . . . . . . . . . . .divide by 14

Suppose you want to buy a $158,000 home. You found a bank that offers a 30-year loan at 4.9%
APR.
What will be your monthly payment? (Round to the nearest cent.)

Answers

Step-by-step explanation:

300000 will be your monthly payment.

Answer:

I believe monthly payment would be $645.17

Step-by-step explanation:

Interest = Principal x rate x time

Interest = 158000(.049)(30)

Interest = $232,260

Principal + Interest = 390,260

390,260 divided by 360 months (30 yrs at 12 months per yr) = 645.17

Russell has collected 12 ties. If 2 out of every 3 ties
are black with different colored stripes, how many black ties with different
colored stripes does Russell own?

Answers

Russel will own 8 black with different colored stripe ties.

If he has a total of 12 ties, and 3 ties per set, there will be 4 groups of 3 because 3 times 4 equals 12

If 2 out of 3 ties are black with different colored stripes, and there are 4 sets, we would multiply 2 and 4, which will give you 8
