Answer:

m = 5

a = -3

b = -15

Step-by-step explanation:

(m - 2) = 3 for x^2

(2a + 3) = - (m - 2) = (2 - m) for x^1

(b + 6) = (2a - 3) for x^0

Percentages are just fractions with a denominator of 100. To show that a number is a percentage, we place the percent sign (%) next to it. For instance, if you properly answered 68 out of 100 questions on a test, you would have received a 68% grade (68/100).

According to the given information

Let \(P(0)\) be initial population

and K be the growth rate

Then Population of the country after t years

\(P = P(0)e^{Kt}\)

Let x be the present population

2x will be the double of present population

And we know

The growth rate K = 0.02%

So

The value of t could be determined as follows

\(xe^{0.02t}=2x\)

\(e^{0.02}=2\)

\(0.02t=ln(2)\)

Multiply both sides by 1000

0.02t × 1000 = ln(2) × 1000

Refine

20t = ln(2) × 1000

Divide both sides by 20

\(\frac{20t}{20}=\frac{ln(2).1000}{20}\)

t = \(ln(2).500\)

t = 0.693×50

t = 34.65 years

t = 35 years

It will take 35 years to double the population

Answer:

The probability that both Jun and Deron get hired=0.2

Step-by-step explanation:

Let

A=Jun

B=Deron

We are given that

The probability that Jun gets the job, P(A)=0.7

The probability that Deron gets the job, P(B)=0.4

The probability that at least one of them gets hired, \(P(A\cup B)=0.9\)

We have to find the probability that both Jun and Deron get hired.

We know that

\(P(A\cup B)=P(A)+P(B)-P(A\cap B)\)

Using the formula

\(0.9=0.7+0.4-P(A\cap B)\)

\(P(A\cap B)=1.1-0.9\)

\(P(A\cap B)=0.2\)

Hence, the probability that both Jun and Deron get hired=0.2

Answer:

Step-by-step explanation:

You want to know if the given distance calculations are correct (true) or not (false).

The distance between the animals at different coordinates is the absolute value of the difference of the coordinates.

The distance is ...

  |(-38 1/2) -(-84 1/4)| = 45 3/4 . . . . True

The distance is ...

  |-145 -(-84 1/4)| = 60 3/4 ≠ 229 3/4 . . . . False

The distance is ...

  |(18 3/4) -(-38 1/2)| = 57 1/4 . . . . True

The distance is ...

  |(18 3/4) -(-145)| = 163 3/4 ≠ 126 3/4 . . . . False

__

Additional comment

Since we're using the absolute value function, the order in which the subtraction occurs is immaterial. In the first two calculations we subtracted the location of the second animal from the first. In the last two calculations, this order was reversed. The correct distance is found either way.

If you don't use the absolute value function, you want to subtract the smaller coordinate from the larger. This will always give a positive result.

As a rule, distance and length are always positive. Displacement or position can be negative.

Answer:

Step-by-step explanation:

Okay, So we're given that the amount of time it takes for class one to end is normally distributed. The amount of time it takes for the class to to start is normally distributed. And the amount of time it takes to get from class one to class two is also normally distributed. And they have these normal distributions, I have been down here. X one is the time that it takes to get to The time it takes for the first class to end. X two is the time it takes for the second class to begin. An X three is the time It takes to get from Class 1 to class too. So what I'm gonna do is I'm gonna let t equal X one plus X three and X one plus X three is the time it takes for the first class to end, added to the time it takes to get from class one to class too. So this will be equal to This will be equal to do one of these lines is equal to a normal distribution where we add the main values and we add the variances and this is allowed because all three of these are normally distributed and they're all independent of each other. We can do that when they're independent of each other. So if we add 902-6 minutes we get 908 and if we add one squared to 1.5 squared 1.5 squared is 2 to 5. So this is 3 to 5. And now that we have this normal distribution of the time it takes to get to class two added to the time it takes for the first class to end. We can now set this up With this 3rd distribution. So what we're trying to find is we want this time this normal distribution to be less than at the time it takes for the class to to start. So this normal distribution, so we want t To be less than X two. And so what we're gonna do now is I'm gonna rewrite this by just minus ng ti from both sides. So you get zero Is less than X two -T. And now we can set this up as another normal distribution by minus ng the two means and then we still add the variances. So this would be normal Where we have 908. We're sorry, we have 9 10 minus 98 just to two minutes and we have 3.25 Added to one squared up here. So that is 4.25 as our variants. And now what we can do is just set up a Z score. So right now we want to find the probability that X two minus T is greater than zero, but I'm going to change this. So we've found the probability of Z is greater than 0-. Are you divided by our variance? I'm sorry, our standard deviation and this will let us use then the standard normal distribution table to find our probability. So if we let zero minus you, if we set up this, so we actually find zero minus, you will use to so we know zero minus you is negative two and the standard deviation, It's just the square root of our variance, which is 4-5. So we're trying to find the probability that Z is greater than -2 over the square to 4.25. And we can do this by setting this up a different way, we can say that this is equal to one minus the probability that Z is actually less than or equal to -2 over the square to 4.25. And this will make it. So we can actually look at our distribution table And find the value that we need to, which is the value at -2 divided by the square to 4.25. So if we simplify this further, We'll see that -2 divided by the square Of 4-5, goes to about -97. And now if we go and look at our Normal distribution table, we'll see that the value at negative .97 Is just about .16 60 And so now all we have to do is take one and subtract this value of .1660. And we'll get a resulting value of .834, which is then our probability.

Step-by-step explanation:

The units digit of a number raised to a power depends on the units digit of the base number and the value of the exponent. The units digit of 6543 is 3. The last digit of powers of 3 repeat in a cycle of numbers – 9, 7, 1 & 3. Since 8901 is one more than a multiple of 4 (8900), the units digit of 6543^8901 is the same as the units digit of 3^1, which is 3.

We may deduce from the average speed that the aircraft must have at least once during the flight attained a speed of 478.72or higher.

This implies that the aircraft must have surpassed 100 mph once while descending to its average speed following takeoff.

So,

We can write,

The speed of the aircraft decreased throughout the arrival from its usual speed to 100 miles per hour before returning to zero at the destination.

Based on the given conditions,

Total distance of the flight = 2250 miles

Flight takeoff time = 2:00 pm

Arrival time of the flight = 7:40 pm

So,

The total time taken by the flight to cover 2250 = 4 hours 40 minutes

The total time is taken by the flight to cover 2250 = 4.7 hours

Then,

The average speed of the plane =Total distance/ total time

We can substitute values,

total distance = 2250,

total time = 4.7 hours

The average speed of the plane = 2250÷4.7

The average speed of the plane  is 478.72 miles per hour

From the average speed we can analyze that the plane must have reached the speed of 478.72 or more at least once during the journey this also concludes that the plane must have reached the speed of 100 miles per hour once while reaching to the average speed after the takeoff.

Hence,

During the arrival, the speed of the plane also reached went from the average speed to 100 miles per hour and then zero at the arrival destination

Therefore,

There were at least two times during the flight when the speed of the plane was 100 miles per hour.
