Answer:

1

Step-by-step explanation:

Given the following :

Rate of arrival = 40 ( poisson distribution)

Average copying time = 40 seconds (according to an exponential distribution)

Number of machines available = 1

Percentage of time machine is used is Hence ;

Rate of arrival / (Average copying time × number of machines)

40 / (40 × 1)

= 40 / 40

= 1

Answer:

189 is the next number bacause we multiply 3+3+3=9 now, 9+9+3=21, again ,21+21+3=45 ,again 45+45+3, therefore we observed that this number add itself and its last add 3 so, 93+93+3=189

The next term will be of the sequence is 189.

A sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members. The number of elements is called the length of the sequence.

According to the question

The sequence:       3,    9,    21,    45,    93,

Next term be x

The sequence:       3,    9,    21,    45,    93,    x

Difference :                 6    12      24     48    

as we can see that

every difference is difference of previous terms *2

i.e

6*2 = 12

12*2 = 24

24*2 = 48

48*2 = 96

Therefore ,

The sequence:       3,    9,    21,    45,    93,    x

Difference :                 6    12      24     48    96

i.e

x = 96 + 93

x = 189

Hence , the next term will be of the sequence is 189.

Answer:

615.44 in²

Step-by-step explanation:

Use the circumference formula, C = 2[tex]\pi[/tex]r

Plug in the circumference and pi to solve for the radius, r:

C = 2[tex]\pi[/tex]r

87.92 = 2(3.14)r

87.92 = 6.28r

14 = r

Then, use the area formula, A = [tex]\pi[/tex]r²

A = 3.14(14)²

A = 615.44 in²

So, the area of the mirror is 615.44 in²

Answer:

Scale factor of 1

Step-by-step explanation:

A scale factor is a number in which the length of every segment of an original figure is multiplied by to get a new figure similar to it.

A scale factor that is less than 1 would give us a new figure that is reduced and smaller than the original figure. On the other hand, if the scale factor is greater than 1, the new figure would be an enlargement if the original figure.

However, a scale factor = 1 will give us a figure that is congruent to the original figure. No enlargement or reduction in the original size. The figure it image remains the same.

Answer:

24:56 is equivalent to 3:7

Step-by-step explanation:

All you have to do is divide 24:56 by 8.

1. 24 ÷ 8 = 3

2. 56 ÷ 8 = 7

And there you go = 3:7

Step-by-step explanation:

You have to put the numbers in order then find the middle number.

Numbers in order: 2,3,6,6,7,8,8,8,15

Then cross out the numbers on the end (one by one) until you get to the middle number. (If there are two numbers left once you're done then you add them then divide by 2)

Answer:

Step-by-step explanation:

2x + 4 = 6x - 10

Minus 2x on both sides

4 = 4x - 10

Add 10 on both sides

14 = 4x

Divide by 4 on both sides

14/4 = x

x = 14/4

Simplify fraction

x = 7/2 or x = 3 1/2

Answer:

180°-(68°+37°)→→→→→→→→sum of angles on a straight line.

180-105=75°

Point to be kept in mind : the sum of angle of a straight line is 180°!

Thus,

68+ X + 37 = 180

=> 105 + X = 180

Answer:

Step-by-step explanation:

Given the expression chase was asked to simplify as [tex](-3) ^ 4 * (-3) ^ 9[/tex], lets first solve and compare our solution with chases's

Using the law of indices [tex](a) ^ m * (a) ^ n = a^{m+n}[/tex]

[tex]= (-3) ^ 4 * (-3) ^ 9 \\\\= (-3)^{4+9}\\\\= (-3)^{13}[/tex]

Chases reasoning is wrong according to his answer [tex](-3) ^ 4 * (-3) ^ 9 = (-3)^ {36}[/tex]. What chase's did was to multiply the power of -3 together instead of adding. In indices when the bases are equal and we are multiplying, the powers of the bases will be added not multiplies=d as chase's did.

Step-by-step explanation:no

Answer:

Step-by-step explanation:

Let y(t) = vt..... 1

Differentiating y(t) with respect to t twice will give;

y'(t) = v(1) + v't

y'(t) = v+v't .... 2

For y''(t);

y''(t) = v'+v'(1)+v''t

y''(t) = 2v'+v''t.... 3

Substitute equation 1, 2 and 3 into the differential equation

t²y′′−t(t+3)y′+(t+3)y=0

t²(2v'+v''t) −t(t+3)(v+v't)+(t+3)(vt)=0

t²(2v'+v''t) −(t²+3t)(v+v't)+(t+3)(vt)=0

Open the parentheses

2t²v'+t³v''-(t²v+t³v'+3tv+3t²v')+t²v+3vt= 0

2t²v'+t³v''-t²v-t³v'-3tv-3t²v'+t²v+3vt=0

Collect like terms according to the degree

t³v''+2t²v'-3t²v'-t³v'-t²v+t²v-3vt+3vt=0

t³v''-t²v'-t³v' =0

t²(tv"-v'-tv') = 0

tv"-v'-tv' = 0

tv"-v'(1+t) = 0

Reduce the degree by substituting p as v' to have;

tp'-p(1+t) = 0

tp' = p(1+t)

Separate the variables

p'/p = (1+t)/t

p'/p = 1/t + 1

Integrate both sides of the equation

ln(p) = lnt + t +K

lnp-lnt = t+K

ln(p/t) = t+K

p/t = e^(t+K)

p = Cte^t

v' = Cte^t

Integrate both sides

v = C{te^t - integral (e^t)}

v(t) = C(te^t - e^t}

y(t)/t = C(te^t - e^t}

y(t) = C(t²e^t-te^t)

Since the solution of second order differential equation

y(t) = C1e^at+C2te^t

In comparison the second solution to the differential equation y(t) will be t²e^t

Answer:

A rational number is any number that can be written as a ratio of two integers (hence the name!). In other words, a number is rational if we can write it as a fraction where the numerator and denominator are both integers. ... Irrational, then, just means all the numbers that aren't rational.

1/5 is the same as 2/10. How many 2's can you put in 9? You can put 4.5 2's in a 9. However, filling half a bag does not fill the entire bag, so the answer would be 4. You can fill 4 full 1/5 pound bags with 9/10 pounds of granola.
