Unlikely is the answer because
certain would be 100
impossible would be 0
and its unlikely because 1/4 is 25 (unlikely)

Hey!

Let's see here. If an event occurs only $\frac{1}{4}$ of the time out of $\frac{4}{4}$ of the time, then it will probably never happen again. If your not good with fractions, the best way to solve this problem would be to use or create a pie chart that represents the situation.

Below the answer, I have provided a pie chart for you take a look at. Notice how the graph is shaded in two different colors. The part of the graph that is shaded orange represents the $\frac{1}{4}$ probability of the event occurring again. And the area shaded in green represents the rest of the whole.

The orange portion of the pie chart is much less than that which is green.

This shows us that the likelihood of that event occurring again is in fact unlikely.

Hope this helps!

Answer:

1. $(-2^2)^{-6}$ ÷ $(2^{-5})^{-4} \implies 2^{-32}$

2. $2^4 . (2^2)^{-2} \implies 1$

3. $(-2^{-4}).(2^2)^0 \implies -2^8$

4. $(2^2).(2^3)^{-3} \implies 2^{-5}$

Step-by-step explanation:

1. $(-2^2)^{-6}$ ÷ $(2^{-5})^{-4}$ :

$= \frac{ ( - 2 ^ 2 ) ^ { - 6 } } { ( 2 ^ { - 5 } ) ^ { - 4 } } = \frac{2^{-12}}{2^{20}} = 2^{-12-20}=2^{-32}$

2. $2 ^ 4 . ( 2 ^ 2 ) ^ { - 2 }$ :

$= 2^4 \times \frac{1}{2^4} = 1$

3. $(-2^{-4}).(2^2)^0$ :

$= (-2^4)^2 \times 1 = -2^8$

4. $(2^2).(2^3)^{-3}$ :

$= 2^4 \times \frac{1}{2^9} =\frac{1}{2^5} =2^{-5}$

How to know how to solve properties of parallelograms

Archy [21]

Answer:

Opposite sides are corresponding (AB = DC).

Opposite angles are corresponding (D = B).

Consecutive angles are supplementary (A + D = 180°).

If one angle is right, then all angles are right.

The diagonals of a parallelogram hemisect each other.

Suppose an economy experiences an increase in unemployment across all industries. What is the result of this increase in unemplo

Nastasia [14]

Production would take place at a point inside the production possibility frontier

The Production possibilities curve is a curve that shows the various combination of two goods a company can produce when all its resources are fully utilised.

The PPC is concave to the origin. This means that as more quantities of a product is produced, the fewer resources it has available to produce another good. As a result, less of the other product would be produced. So, the opportunity cost of producing a good increase as more and more of that good is produced.

Points inside the production possibilities curve means that the nations resources are not being fully utilised

When the unemployment rate increases, it means that labour resources are not been fully utilized. As a result, production would take place at point inside the production possibilities curve

Point outside the curve or to the right of the curve means that the production level is not attainable given the level of resources

A. x-int:-0.5,y-int:1 B. x-int:0.5,y-int:1 C. x-int:-0.5,y-int:-1 D. x-int:1,y-int:0.5

hodyreva [135]

The correct answer is: [D]: " x-int : 1 , y-int: 0.5 " .

The "x-intercept" refers to the point(s) at which the the graph of a function (which is a "line", in this case) cross(es) the "y-axis".

In other words, what is (are) the point(s) of the graph at which "x = 0" ?

By examining the graph, we see that when " x = 0" ; y is equal to: "1" .

So; the "x-intercept" is at point: "(0, 1)" ; or, we can simply say that the
"x-intercept" is: "1" .
