Answer:

$y - 7 = \frac{1}{4}(x + 2)$

Step-by-step explanation:

Insert the coordinates into the formula with their CORRECT signs. Remember, in the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE terms of what they really are. Plus, perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE RATE OF CHANGES [SLOPES] so −4 becomes ¼.

Answer:

The French restaurant did not use cream this year, due to a menu update.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of cream used by a French restaurant last year = 92.870 ounces

Amount of cream used by the French restaurant this year = 100% less

2. How much cream did the restaurant use this year?

The answer is zero and we calculated it this way:

92,870 - 100% (92,870) = 92,870 - 92,870 * 1 = 92,870 - 92,870 = 0

The French restaurant did not use cream this year, due to a menu update.

Answer:

The chance of getting exactly 3 hits is = 0.20

Step-by-step explanation:

P.S - The exact question is -

As given,

F(x) = 0 , x < 1

0.30 , 1 ≤ x < 2

0.56 , 2 ≤ x < 3

0.76 , 3 ≤ x < 4

0.9 , 4 ≤ x < 5

1 , 5 ≤ x

Now,

f(x) = 0.30 , x = 1

0.56 - 0.30 = 0.26 , x = 2

0.76 - 0.56 = 0.20 , x=3

0.9 - 0.76 = 0.14 , x = 4

1 - 0.9 = 0.1 , x = 5

0, otherwise

Now,

The chance of getting exactly 3 hits is = f(x = 3) = 0.20
