There are 10 sweets in a bag.

Valentin [98]

Answer:

See Explanation Below

Step-by-step explanation:

Given

Total Sweets = 10

Red = 4

Green = 2

Yellow = 3

Purple = 1

Required

a & b

The question is not properly presented; however the solution is as follows;

Let P(Yellow) represent the probability of selecting a yellow sweet and n(Yellow) represent the number of Yellow sweets;

$P(Yellow) = \frac{n(Yellow)}{Total}$

$P(Yellow) = \frac{4}{10}$

$P(Yellow) = 0.4$

So, whichever letter that shows $0.4$ or $\frac{4}{10}$ is the probability of choosing a yellow sweet

Let P(Orange) represent the probability of selecting an orange sweet and n(Orange) represent the number of orange sweets;

Since, there's no orange sweet in the bag;

$n(Orange) = 0$

$P(Orange) = \frac{n(Orange)}{Total}$

$P(Orange) = \frac{0}{10}$

$P(Orange) = 0$

In probability; opposite probabilities add up to 1;

Let P(Not\ Orange) represent the probability of choosing a sweet that is not orange

$P(Not\ Orange) + P(Orange) = 1$

Substitute $P(Orange) = 0$

$P(Not\ Orange) + 0 = 1$

$P(Not\ Orange) = 1$

So, whichever letter that shows 0 is the probability of choosing a sweet that is not orange

A quadrilateral has two right angles. The measure of the third angle is 99 degrees. What is the measure of the fourth angle.

kogti [31]

since it is a quadrilateral, all the sides will add to 360. If two angles are 90, and one is 99, add them and subtract from 360. The last angle should be 81 degrees.

What is the answer?

Answer:

5.6 cm^2 : y (as actual area)

y = 200 mutifly 5.6 cm^2

y= 1120 cm^2

We know 1m =100cm

so, 1m^2 =100cm x 100 cm = 1000cm^2

y= 1120 m^2/ 100x100

= 0.112 m^2

Select the correct answer from the drop-down menu.

Missing term = –2xy

Solution:

Let us first find the quotient of $-8x^2y^3 \div xy$ .

$-8x^2y^3 \div xy=\frac{-8x^2y^3 }{xy}$

$=\frac{-8\times x\times x\times y\times y\times y}{xy}$

Taking common term xy outside in the numerator.

$=\frac{xy(-8\times x\times y\times y)}{xy}$

Both xy in the numerator and denominator are cancelled.

$=-8xy^2$

Thus, the quotient of $-8x^2y^3 \div xy$ is $-8xy^2$ .

Given the quotient of $-8x^2y^3 \div xy$ is same as the product of 4xy and ____.

$-8xy^2=4xy$ × missing term

Divide both sides by 4xy, we get

⇒ missing term = $\frac{-8xy^2}{4xy}$

Cancel the common terms in both numerator and denominator.

⇒ missing term = –2xy

Hence the missing term of the product is –2xy.
