Answer:

True, for Probability of a chance event certain to happen is 1.

Step-by-step explanation:

Given that,

A chance of event with probability of happening certainly is 1.

To find:- Is it true or false?

from the given scenario,

Probability states that P(Event) is a number describing the chance of that event will happen And value of $P(E)$ lies between $0\leq P(E)\leq 1$ ..

$P(An Event) =$ $\frac{Number of favourable outcomes}{Total number of outcomes}$

When An Event is certain to occur then its $P(E) = 1$ .

when An Event cannot possible to occur then its $P(E) = 0$ .

And

Is there any chance that event will occur then its value lies $0\leq P(E)\leq 1$ .

Let us take an Example:-

If it is Saturday, then the probability that tomorrow is Sunday is certain, therefore the probability is 1.
The probability that tomorrow is Friday if today is Sunday is 0.

Hence,

True, for Probability of a chance event certain to happen is 1.

Can you double a square with a straightedge and a compass?

sergejj [24]

I'd say yes. If you use the diagonal as a reference. Take the square and set your compass to the width of the diameter of the square. Now put it on the page and mark a point. Put the point of the compass on that mark and make another mark. Now you can connect the two marks with the straight edge and you have a line that, if you made a square with sides that long, it'd have 2x the area of the first one. That's because the diagonal is the square root of 2 larger than one side. Square the square root of 2 and you've got 2. You lust need to make a perpendicular line to the first one to get the box going.

Answer: $x=5$

Step-by-step explanation:

Step 1:-

Given equations are y=-2 x+30........(1)

another equation is y=4 x ..........(2)

Step 2:-

solving these two equations (1) and (2)

Equating both equations are $4 x = -2 x+30$

$4 x+2 x =30$

$6 x =30$

Step 3:-

The final answer is $x=5$

the population of masterton was 23 000 in 2012. Assume that Masterton population increases at a rate of 2% per year. Write an eq

Oksanka [162]

So, let's first focus on the first year:

the population then would be: 23000* (100+2)%

100% is the old population the 2% is the incease, so in total it's 102%, or 1.02 - the same number written differently.

So it will be 23000*1.02

After two years it will be 23000*1.02*1.02, and so on

so after x years it will be:

y=23000* $1.02^{z}$
