Find the product. (–5k + 5)(–5k2 + 2k – 8)
boyakko [2]

Answer:

25 K³ - 35k²+ 50 K - 40

===========================================

Step-by-step explanation:

Given that :

(-5k + 5)(-5k² + 2k - 8)

= -5K (-5k² + 2k - 8) + 5 (-5k² + 2k - 8)

= 25 K³ - 10k² + 40 K - 25 K² + 10 K - 40

= 25 K³ - 35k²+ 50 K - 40

<u>So, the product = 25 K³ - 35k²+ 50 K - 40</u>

I just need help cause if I don’t I don’t know what imma do
erica [24]

Answer:

P(32) = \frac{1}{90}

P(Odd) = \frac{1}{2}

P(Multiples\ 5) = \frac{1}{5}

Step-by-step explanation:

Given

Sample Space = 10 to 99

First, we calculate the sample size (n)

n = 99 - 10 + 1

n = 90

Solving (a): P(32)

In 10 to 99, there is only 1 32.

So,

P(32) = \frac{n(32)}{n}

P(32) = \frac{1}{90}

Solving (b): P(Odd)

There are 45 odd numbers between 10 and 99

i.e.

n(Odd)  = 45

So:

P(Odd) = \frac{n(Odd)}{n}

P(Odd) = \frac{45}{90}

P(Odd) = \frac{1}{2}

Solving (c): P(Multiple of 5)

There are 18 multiples of 5 between 10 and 99

i.e

P(Multiples\ 5) = \frac{18}{90}

P(Multiples\ 5) = \frac{1}{5}
