Let's solve the first inequality at first. So,

−2(x + 4) + 10 < x − 7

-2x- 8 + 10 < x - 7 By distribution property.

-2x + 2 < x - 7 Adding the like terms.

-2x < x - 7 - 2 Subtract 2 from each sides.

-2x < x - 9 By simplifying.

-2x - x < -9 Subtract x from each sides.

-3x < -9

-\frac{3x}{3}

Since we are dividing by negative 3. So, sign of inequality will get change.

So, x>3

Now the next inequality is,

−2x + 9 > 3(x + 8)

-2x + 9 > 3x + 24

-2x > 3x + 24 - 9

-2x > 3x + 15

-2x - 3x > 15

-5x >15

-\frac{5x}{-5} >\frac{15}{-5}

So, x <-3

Hence, the correct choice is x > 3 or x < −3.

Say a business found that 98.3% of soda cans at a production facility in California are filled correctly. The company chooses 10
Shtirlitz [24]

Answer:

The events must be independent.

Step-by-step explanation:

The only assumption that must be made is that the events are independent. That is, the amount of soda in a given can does not depend on the amount of soda of any previous can filled at the same facility.

If this assumption holds, then the probability of finding exactly k cans of soda filled correctly would be

\displaystyle\binom{100}{k}(0.983)^k(1-0.983)^{100-k}

where

\displaystyle\binom{100}{k}=\displaystyle\frac{100!}{k!(n-k)!}

are combinations of 100 elements taken k at a time.

How do u solve 4p - 40 = 7(-2p + 2) ?
mr Goodwill [35]

Answer:

Simplifying

4p + -40 = 7(2p + 2)

Reorder the terms:

-40 + 4p = 7(2p + 2)

Reorder the terms:

-40 + 4p = 7(2 + 2p)

-40 + 4p = (2 * 7 + 2p * 7)

-40 + 4p = (14 + 14p)

Solving

-40 + 4p = 14 + 14p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-14p' to each side of the equation.

-40 + 4p + -14p = 14 + 14p + -14p

Combine like terms: 4p + -14p = -10p

-40 + -10p = 14 + 14p + -14p

Combine like terms: 14p + -14p = 0

-40 + -10p = 14 + 0

-40 + -10p = 14

Add '40' to each side of the equation.

-40 + 40 + -10p = 14 + 40

Combine like terms: -40 + 40 = 0

0 + -10p = 14 + 40

-10p = 14 + 40

Combine like terms: 14 + 40 = 54

-10p = 54

Divide each side by '-10'.

p = -5.4

Simplifying

p = -5.4
