Answer:

40

Step-by-step explanation:

The area of a rectangle is length*width. So, 200=8(1/2x+5). Dividing by 8, 25=1/2x+5. Subtracting 5, 20=1/2x, multiplying by 2, 40=x.

Francine applies the commutative property to the product. (−8/9)⋅(−13)⋅(18) Which expression illustrates the commutative propert
oksian1 [2.3K]

The commutative property implies that, the order of multiplication is not important.

(-\frac 89) \cdot (18) \cdot (-13) is true

Commutative property of multiplication states that:

If a \times b  = b \times a

The expression is given as:

(-\frac 89)\cdot (-13) \cdot (18)

To get the commutative expression, we simply change the position of each factor in the expression.

So, some possible equivalent expressions are:

(18) \cdot (-13) \cdot (-\frac 89)

(18)\cdot (-\frac 89) \cdot (-13)

(-13) \cdot (18) \cdot (-\frac 89)

There are several other equivalent expressions.

From the list of options;

(-\frac 89) \cdot (18) \cdot (-13) is true

Over [174]

Answer:

6 red balls

Step-by-step explanation:

The probability in the first pick

6/21

The probability in the second pick (without replacement)

5/20

the requested probability

(6/21)(5/20) = 30/420

simplification

30/420 = 3/42 = 1/14

Hope this helps

Can somebody who knows how to do probability please help answer these questions correctly? Thanks! (Btw the P= probability)
stira [4]

Answer:

P(2): 1/5

P(4): 1/5

P(odd number): 3/5

P(whole number): 5/5

P(6): 0/5

P(2 or 3): 2/5

Step-by-step explanation:

There are 5 <em>equal </em>sections in this circle. So, the probability to land in each section is 1/5.

The odd numbers are 1, 3, and 5. Since each section is 1/5, you add

1/5 + 1/5 + 1/5 = 3/5. That is the probability that you will land in any odd number.

Because all the numbers listed are whole numbers, no matter where the spinner lands it will be a whole number. So, the probability is 5/5 for whole numbers.

Since 6 is not a section, it's probability will be 0/5 (or you can just put 0).

"Or" means you add the two probabilities. Add the probability of landing on 3 (which is 1/5) to the probability of landing on 2 (which is also 1/5). So, you get 2/5.
