Compare and contrast the following two equations. Determine if they are linear equations and explain why or why not.

Answer:

the answer should be 1/11

Step-by-step explanation:

p(blue first) = 3/12

p(yellow second) = 4/11

so p = 3/12 x 4/11

1/11 is your probability

Answer:

So first we need to determine what the exponential growth function would look like.  Exponential growth functions look like [tex]P(t) = P_0*e^{r*t}[/tex] and in our case [tex]P_0[/tex] would be the initial population which is 5.68 million.  R is the next variable that we need to fill out which is the rate of change which in our case is 2.99% or 0.0299.

This is how our function should look now [tex]P(t)=5.68*e^{0.0299*t}[/tex]

Moving onto part b, we need to estimate the population of the city in 2018 which 6 years from 2012 and we plug that into t and solve.

[tex]P(t)=5.68*e^{0.0299*6}[/tex]

[tex]P(t)=5.68*e^{0.1794}[/tex]

[tex]P(t) = 5.68*1.1965[/tex]

[tex]P(t) = 6.796\ million[/tex]

Moving onto part c, we need to find when the population of the city will be 11 million which will be done by setting P(t) to 10 million and solving for t.

[tex]10 = 5.68*e^{0.0299*t}[/tex]

[tex]\frac{10}{5.68} = \frac{5.68*e^{0.0299*t}}{5.68}[/tex]

[tex]1.76056=e^{0.0299*t}[/tex]

[tex]ln(1.76056)=ln(e^{0.0299*t})[/tex]

[tex]\frac{0.5656}{0.0299}=\frac{0.0299*t}{0.0299}[/tex]

[tex]18.9175\ years = t[/tex]

Moving onto part d, we need to find the doubling time.  This will be similar to the previous part but we will be finding the time it takes to double our population.  So instead of putting 10 million for P(t) we put 5.68* 2 in there which is 11.36.

[tex]11.36= 5.68*e^{0.0299*t}[/tex]

[tex]\frac{11.36}{5.68} = \frac{5.68*e^{0.0299*t}}{5.68}[/tex]

[tex]2=e^{0.0299*t}[/tex]

[tex]ln(2)=ln(e^{0.0299*t})[/tex]

[tex]\frac{0.693}{0.0299}=\frac{0.0299*t}{0.0299}[/tex]

[tex]23.182\ years = t[/tex]

Step-by-step explanation:

First, we need to find the mean of the given data set without any change.

10 + 61 + 10 + 44 + 21 + 79 + 27 + 12 = 264

264 ÷ 8 = 33

Now that we have the mean, we can find the mean of the data set with the change of 52.

10 + 61 + 10 + 44 + 21 + 79 + 27 + 52 = 304

304 ÷ 8 = 38

From this, we can see that the mean has increased with the change of 12 to 52. Thus, that's the correct option.

The length of the straw will be 9.89949 inches long in radical form.

If a cuboid has length = l units, breadth = b units, and height = h units, then we can evaluate the length of the diagonal of a cuboid using the formula

[tex]X^2=l^2+b^2+h^2[/tex]

As per the question the length of the straw is equal to length of the diagonal of Rectangular box.

l= 5 inch , b= 8 inch , h= 3 inch

Let us consider the length of the straw be 'x'.

As, Diagonal of Cuboid is,

[tex]X^2+l^2+b^2+h^2[/tex]

[tex]X^2=5^2+8^2+3^2[/tex]

[tex]X^2=25+64+9[/tex]

[tex]X^2=98[/tex]

[tex]X=\sqrt{98}[/tex]

X= 9.89949 (in radical form)

Hence, the length of the straw will be  9.89949 inches.

Answer:

Multiplication is the process of multiplying. The total cost of the boxes of two types is $90.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The cost of the first box is $12, which has 8 pounds of milk chocolate and 4 pounds of dark chocolate.

The cost of the second box is $15, which has 5 pounds of milk chocolate and 10 pounds of dark chocolate.

Therefore, if we buy the 5 boxes of the first type and 2 boxes of the second type, then the amount of two chocolate that Tim needs will be fulfilled.

The cost of 5 boxes of the first type is $60 ($12 ×5), while the cost of 2 boxes of the second type is $30 ($15×2), therefore, the total cost of the boxes of two types is $90.

Since the sequence has a common difference of 5, hence the sequence  is 4, 9, 14, 19, ... is defined recursively using the formula  f(n 1) = f(n) – 5 .

Recursive functions are functions used to generalize sequence. Given the recursive function

f(n - 1) = f(n) – 5 .

This can be written as:

f(n) - f(n-1) = 5

This shows that the correct sequence must have a common difference of 5

For the sequence 4, 9, 14,19...

d = 9 - 4 = 14 - 9

d = 5

Since the sequence has a common difference of 5, hence the sequence  is 4, 9, 14, 19, ... is defined recursively using the formula  f(n 1) = f(n) – 5

Answer:

x = 42°

Step-by-step explanation:

Given that,

→ A = 48°

→ B = 90°

→ C = x

Formula we use,

→ A + B + C = 180°

Let's solve for the value of missing angle,

→ A + B + C = 180°

→ 48° + 90° + x = 180°

→ 138° + x = 180°

→ x = 180° - 138°

→ [ x = 42° ]

Hence, value of missing angle is 42°.

  arc BC = 26°

  arc AB = 90°

  arc CAB = 334°

Step-by-step explanation:

The angles of a linear pair total 180°. This fact lets us write an equation for x that helps us find the measures of all the angles and arcs. The arcs of a circle total 360°.

__

∠APE +∠EPD = 180°

  (25x +15)° +(33x -9)° = 180°

  58x = 174 . . . . . . divide by °, subtract 6

  x = 3 . . . . . . . . divide by 58

Angle APE is ...

  ∠APE = (25x +15)° = (25·3 +15)° = 90°

Then ...

  ∠EPD = 180° -90° = 90°

  ∠DPC = (20·3 +4)° = 64°

  ∠CPB = 90° -64° = 26°

  arc BC = ∠BPC = 26°

  arc AB = ∠APB = 180° -90° = 90°

  arc CAB = 360° -arc AB = 334°

Answer:

Option A

Step-by-step explanation:

95% confidence interval is obtained using the following formula

COnfidence interval lower bound = mean - critical value * sigma/sq rt n

and upper bound = mean + critical value*sigma/sq rt n

Thus margin of error = critical value*sigma/rt n

varies indirectly as n provided others are remaining the same.

Hence lower sample indicates higher margin of error

Out of 4 options given we find that I option has maximum margin of error as 21%

Hence option A is most likely coming from a small sample
