AE is about half of AC. What I did was get half of 28, which is 14, and represented one of the numbers.
3 x 7 = 21 - 7 = 14
It is D.
(I don't know for sure if this is right, but I did the best I could)

"which of the numbers below can be classified as an integer" and the options are . 10÷2 , -0.3 ,√20 ,. 0.4​
Ivahew [28]

Answer:

The number 10/2 = 5 is an integer.

Step-by-step explanation:

An integer is a whole number which cannot be expressed in fractions. For example, 1, 2, 3...

Integer can be positive,  negative of zero.

\frac{10}{2}=5

It is a whole number so it is an integer.

- 0.3

It is not an integer as it has a fractional part.

\sqrt20

It also has a fractional part, so it is not an integer.

0.4

It also has a fractional part, so it is not an integer.

Fill in each box with the probability of the event that it represents. The following questions can be answered using your area m
Tanya [424]

Answer:

a. \ \dfrac{1}{36}

b. \ \dfrac{4}{9}

c. \ \dfrac{5}{6}

Step-by-step explanation:

The given probabilities are; P(Orange) = 1/3, P(Blue) = 1/6, P(Purple) = 1/2

The probability of rolling any of the six numbers of the six-sided die = 1/6

a. The probability of simultaneously 'rolling a 3' and 'spinning blue', P(3 and Blue) is given as follows;

P(rolling a 3) = 1/6, P(Blue) = 1/6

∴ P(3 and Blue) = (1/6) × (1/6) = 1/36

P(3 and Blue) = 1/36

P(3 \ and \ Blue) = \dfrac{1}{36}

b. The probability of either 'rolling a 1' or 'spinning Orange', P(1 or Orange), is given as follows;

P(rolling a 1) = 1/6, P(Orange) = 1/3

P(1 or Orange) = P(rolling a 1) + P(Orange) - P(1 and Orange)

Where;

P(1 and Orange) = (1/6) × (1/3) = 1/18

∴ P(1 or Orange) = 1/6 + 1/3 - 1/18 = 4/9

P(1 or Orange) = 4/9

P(1 \ or \ Orange) = \dfrac{4}{9}

c. The probability of not spinning a blue, P(not Blue) is given as follows;

P(not Blue) = P(rolling all outcomes of the die) and (The sum of the spin probabilities - P(Blue)

∴ P(not Blue) = 1 × ((1/3 + 1/6 + 1/2) - 1/6) = 1 × (1 - 1/6) = 5/6

P(not Blue) = 5/6

P(not \ Blue) = \dfrac{5}{6}

What is the product?<br><br> 2x(x – 4)
sashaice [31]

Keywords:

<em>Product, factors, polynomial, distributive property </em>

For this case we must find the product of two factors of a polynomial. To do this, we must apply the distributive property, which states: a (b + c) = ab + ac.

So:

2x (x - 4) = 2x * x-2x * 4\\2x (x - 4) = 2x ^ 2-8x

Thus, the product of 2x (x - 4) is: 2x ^ 2-8x

Answer:

The product of 2x (x - 4) is: 2x ^ 2-8x
