intrastate 70 stretches almost 2 ^ 3 * 5 ^ 2 * 11 miles across the United States. About how many miles long is the interest 70?

marshall27 [118]

(2)^3 * (5)^2 * 11

We use PEMDAS so we have to do the exponents first.

2^3 = 8

5^2 = 25

8 * 25 *11

You then go left to right cause they are all multiplication:

200 *11 = 2200 miles

If we buy 20 pickles what is the experimental probability of winning 5 or more tickets

Mrac [35]

Answer:

$Pr = 0.66$

Step-by-step explanation:

Given

See attachment for complete question

Required

$P(x \ge 5)$

From the attachment, we have:

$S = 2 + 8 + 4+20+21+19+17+5+2+2$

$S =100$ ---- the sample size

Next, we list out all outcomes more than or equal to 5.

i.e.

$x \ge 5$

5 is represented with the vertical blue rectangle (with frequency 21).

So, the other elements are to the right of frequency 21.

So, we have:

$x \ge 5 = 21+19+17+5+2+2$

$x \ge 5 = 66$

The probability is then calculated as:

$Pr = \frac{x \ge 5}{S}$

This gives

$Pr = \frac{66}{100}$

$Pr = 0.66$

frutty [35]

Answer:

Step-by-step explanation:

group them first :

( x3+5x2) and ( -6x-30)

then simply by gcf ( greatest common factor) :

x2(x+5) and -6(x+5)

and just add them together:

x2(x+5)-6(x+5)

bonus :

it can be written as (x2-6)(x+5)
