Answer:

The answer to your question is:

a) 1/2

b) 1/2

c) 2

Step-by-step explanation:

a)

          ? x  4 = 2

         1/2 x 4 = 2

         4/2 = 2

         2 = 2

b)

         8 x ? = 4

         8 x 1/2 = 4

         8 / 2 = 4

         4 = 4

c)

       2 x ? = 4

       2 x 2 = 4

           4 = 4

Two number cubes are rolled. Each number cube has sides numbered 1 through 6.

P(odd) or P(multiple of 5)
When we roll 2 number cubes

all possible outcomes of their sum are 2,3,4,5,6,7,8,9,10,11,12.(11 possible outcomes)

Out of those possible outcomes
3,5,7,9,11 are odd (5 outcomes) and ...

5 and 10 are multiples of 5 (2 outcomes)

Now, P(odd) or P(multiple of 5) really means P(odd) + P (multiple of 5) =
(If we had “and” instead of “or” we multiply)
= (5/11) +(2/11)
=7/11

1 point) during a winter season at one ski resort, there are two roads from area a to area b and two roads from area b to area
miss Akunina [59]
Probability that both roads from a to b are blocked is the product of the individual probabilities, i.e.
P(~ab)=0.25*0.25=0.0625
Similarly
P(~bc)=0.25*0.25=0.0625
Probability that EITHER one or both of ab and bc are blocked is the sum of the probabilities:
P(~ab ∪ ~bc)=0.0625+0.0625=0.125
(recall that one cannot travel from a to c if either ab or bc is blocked.)

Therefore the probability that there exists an open route from a to c
= P(ac) = 1-P(~ab ∪ ~bc)
= 1 - 0.125
=0.875

The factorization of x2 + 3x – 4 is modeled with algebra
meriva

Option C: (x+4) and (x-1) are the factors of the equation

Explanation:

Given that the equation is x^{2} +3x-4

We need to determine the factors of the equation.

Splitting the middle term, we get,

x^{2} +4x-x-4

Grouping the terms, we have,

x(x+4)-1(x+4)

Let us factor out the term (x+4), we have,

(x+4)(x-1)

Thus, the factors of the equation are (x+4) and (x-1)

Hence, Option C is the correct answer.

Draw a picture to show the product of 4:7 x 3. Then write the product
Hoochie [10]

Answer:

¹²/₇

Step-by-step explanation:

Model ⁴/₇ × 3

Assume that you have three pies, each dived into seven slices.

There are only four slices remaining in each pie, that is, there is ⁴/₇ pie in each pie plate

The picture represents ⁴/₇ × 3.  

Model the product

Now, transfer slices to get as many filled pie plates as possible.

Count the total slices.

You have 12 slices, and each slice represents ⅐ of a pie.

You have ¹²/₇  pie.

∴ ⁴/₇ × 3 = ¹²/₇
