Slope -4 passing through the point (5,3).

bonufazy [111]

A negative slope means the line would be going downward, so you would go down first (instead of up as with a positive slope), then over right.

Therefore, you would go down 4 (or negative 4 considering you are going down) and right 1.

Rise over run still applies here. Rise over run is a fancy way of saying to put the number (or slope) in fraction form.

-4 as a fraction would be -4/1.

So start at (5,3), go down 4 and over 1, repeatedly and you got it.

**Just remember the rise over run can be confusing with negative slopes.**

To solve the equation X - 62 = 123, you would ?

Ratling [72]

X-62=123
+62 +62
_________
x=185
you need to add a positive 62 from each side so -62+62=0 and 123+62=185
therefore, x=185
:Done! hope this helps!

Jim had some dimes, quarters, and nickels. First, he counted only the dimes and quarters and found that he had 9 coins. Then, he

Olegator [25]

Answer:

$1.90

Step-by-step explanation:

Represent the numbers of nickels, dimes and quarters by n, d and q.

Then: d + q = 9, or q = 9 - d.

Also, n + d = 10

Lastly, n + d + q = 15.

Let's substitute 9 - d for q in the equation immediately above:

n + d + (9 - d) = 15, or n + 9 = 15. Then n must be 6.

In summary, Jim has 6 nickels, (10 - 6) dimes and (9 - 4) quarters, or:

6 nickels, 4 dimes and 5 quarters

Thus, he has 5($0.05) + 4($0.10) + 5($0.25), or

$0.25 + $0.40 + $1.25, or $1.90

Suppose a basketball player has made 291 out of 389 free throws. If the player makes the next 2 free throws, I will pay you $38.

VMariaS [17]

Answer:

The expected value of the proposition is -$0.76.

Step-by-step explanation:

It is provided that a basketball player has made 291 out of 389 free throws.

Then rate of him making a free throw is,

$P(\text{free throw})=\frac{291}{389}=0.7481$

The probability that he makes the next 2 free throws is:

$P(\text{Next 2 free throws})=(0.7481)^{2}=0.5596$

The payout rules are:

If the player makes the next 2 free throws, I will pay you $38.
Otherwise you pay me $50.

Compute the expected value of the proposition as follows:

Expected value = $38 × P (Makes both) + (-$50) × P (Misses both)

$=($38\times 0.5596)+(-$50\times (1-0.5596))\\=21.2648-22.02\\=-0.7552\\\approx -$0.76$

Thus, the expected value of the proposition is -$0.76.
