The correct statement about the earthquake in the state is option c. State A had approximately 3,362 more earthquakes than State B.

we have x/y = 0.00299

y = 163696

To solve for x we have

163696 * 0.00299

= 4895 earthquakes

x = 0.1402 x 10931

= 1533

Next we have to find the difference

4895 - 1533 = 3362 earthquakes.

We have to conclude that state A has 3362 earthquakes more than B. Hence the answer is c.

The seismic activity density of a region is the ratio of the number of earthquakes during a given time span to the land area affected. The table shows the land area and seismic activity density.

Which statement about the number of earthquakes the states had for the given time span is true?

State A had approximately 1,533 more earthquakes than State B.

State B had approximately 1,533 more earthquakes than State A.

State A had approximately 3,362 more earthquakes than State B.

State B had approximately 3,362 more earthquakes than State A.

The correct option is (A). The factored form of a-b is (5-3p⁴)(25+15p⁴+9p⁸).

Given that A and B are monomials where a = 125 and b = 27p¹².

Monomial expressions include only one non-zero term. Numbers, variables, or multiples of numbers and variables are all examples of monomials.

Firstly, substitute a=125 and b = 27p¹² into a-b, we get

a-b=125-27p¹²        ......(1)

As we know, 125=(5)³, 27p¹²=(3p⁴)

So, equation (1) can be rewritten as

a-b=(5)³-(3p⁴)

Now, apply a³-b³=(a-b)(a²+ab+b²).

a³-b³=(5-3p⁴)(5²+5(3p⁴)+(3p⁴)²)

Further, Simplify using exponent rule with the same exponent (ab)ⁿ=aⁿbⁿ.

a³-b³=(5-3p⁴)(5²+5×3p⁴+3²×(p⁴)²)

Furthermore, calculate the power, we get

a³-b³=(5-3p⁴)(5²+5×3p⁴+9(p⁴)²)

Then, Simplify using exponent power rule (aˣ)ⁿ=aˣⁿ, we get

a³-b³=(5-3p⁴)(5²+5×3p⁴+9p⁸)

Now, multiply the monomials, we get

a³-b³=(5-3p⁴)(5²+15p⁴+9p⁸)

Further, calculate the power, we get

a³-b³=(5-3p⁴)(25+15p⁴+9p⁸)

Finally, reorder the expressions, we get

a³-b³=(5-3p⁴)(9p⁸+15p⁴+25)

Hence, the factored form of a-b where a and b monomials and a = 125 and b = 27p¹² is (5-3p⁴)(9p⁸+15p⁴+25).

Answer:a

Step-by-step explanation:

i just did it

(You could do this shorter, but by the time i realized that it was too late.)

First, we need one of the variables (x or y) to have the same coefficient.
Lets use the variable y, since it uses smaller numbers.

Multiply the first equation by the denominator of y, which is 3. Then multiply the second equation by the denominator of y in the second equation, which is 4.

You get:
1st equation: [tex]\frac{3}{2} x+ y = 27[/tex]
2nd equation: [tex]\frac{12}{5}x - 3y=-12[/tex]
Now we need to multiply the first equation by 3, so we can have "3y" in both of the equations.
1st equation: 9/2x + 3y = 81
2nd equation: [tex]\frac{12}{5}x - 3y=-12[/tex]
Now we can subtract both of the equations.
12/5x + 9/2x = 69 We need to make the common denominator for x.
24/10x + 45/10x = 69
69/10x=69
x=10
Now we substitute x into the first equation (or the second, doesn't matter).
1/2 * 10 + 1/3y=9
5 + 1/3y = 9
1/3 y = 4
y = 12

Answer:

(10, 12 )

Step-by-step explanation:

let's begin by clearing the fractions from both equations

[tex]\frac{1}{2}[/tex] x + [tex]\frac{1}{3}[/tex] y = 9 ( multiply through by 6 ( the LCM of 2 and 3 to clear ) )

3x + 2y = 54 → (1)

[tex]\frac{3}{5}[/tex] x - [tex]\frac{3}{4}[/tex] y = - 3 ( multiply through by 20 ( the LCM of 5 and 4 to clear ) )

12x - 15y = - 60 → (2)

multiplying (1) by - 4 and adding to (2) will eliminate x )

- 12x - 8y = - 216 → (3)

add (2) and (3) term by term to eliminate x

0 - 23y = - 276

- 23y = - 276 ( divide both sides by - 23 )

y = 12

substitute y - 12 into either of the 2 equations and solve for x

substituting into (1)

3x + 2(12) = 54

3x + 24 = 54 ( subtract 24 from both sides )

3x = 30 ( divide both sides by 3 )

x = 10

solution is (10, 12 )

The features of the function g(x) = 4log(x) + 4 are

The function is given as;

g(x) = 4log(x) + 4

The intercept

A logarithmic function has no y-intercept.

Set g(x) to 0, to determine the x-intercept

4log(x) + 4 = 0

Divide through by 4

log(x) + 1 = 0

This gives

log(x) = -1

Take the inverse of both sides

x = 10^-1

Evaluate

x = 0.1

The x-intercept is (0.1, 0)

The vertical asymptote

Recall that:

A logarithmic function has no y-intercept.

This is so because it is undefined at x = 0

So, the vertical asymptote is x = 0

The domain and the range

A logarithmic function cannot take a negative input or 0 input

So, the domain is x > 0

However, the range is all set of real numbers i.e (-∞, ∞)

Hence, the features of g(x) are (b), (d) and (e)

Answer:

HI: 17.9

GH: 22.1

Step-by-step explanation:

1) There are three trigonometric ratios for right-angled triangles.

Sin = opposite/hypotenuse

Cos = adjacent/hypotenuse

Tan = opposite/adjacent.

2) Opposite to the 90° lies the hypotenuse. Opposite to the given angle lies the opposite.

Beside the given angle lies the adjacent.

3) The value of G given to us is 54°. The length of GI is 13. We are asked to find the lengths of HI and GH. We cannot find GH (we can, but I prefer the current method) without the length of HI. Let's find HI.

Tan(54) = x/13

Tan(54) × 13 = x

x = 17.89

4) We can use the Pythagorean theorem to find the length of GH. His theorem is c² = a² + b².

c² = a² + b²

c² = 13² + 17.89²

c² = 489.0521

c = √489.0521

c = 22.11

5) Round off the answers to the nearest tenth.

The minimum size of the sample required to ensure that the estimate has an error of at most 0.14 at the 98% level of the confidence interval is 791.

The standard deviation is given as (σ) = 1.69.

The mean number of dresses given (μ) = 7.6.

Margin of error given (M.E.) = 0.14.

Confidence level given = 98%.

Z-Score corresponding to 98% confidence interval (Z) = 2.33.

We are asked to find the minimum size of the sample required to ensure that the estimate has an error of at most 0.14 at the 98% level of the confidence interval.

We assume the size of the sample to be n.

By the formula of Margin of Error:

M.E. = Z*(σ/√n).

Substituting the values, we get:

0.14 = 2.33*(1.69/√n),

or, √n = 2.33*1.69/0.14 = 28.126429,

or, n = 791.096 ≈ 791 (As sample size needs to be a whole number).

Thus, the minimum size of the sample required to ensure that the estimate has an error of at most 0.14 at the 98% level of the confidence interval is 791.

The equation represented by the model is 3x²-4x+1=(3x-1)(x-1).

Given model represents a polynomial of the form ax²+bx and model is in figure.

Consider the given table.

The first row in the table represents first term of the polynomial.

In first row first three terms are variables and last term are constant.

Write all the terms of the first row in the form of sum.

+x+x+x-1=3x-1

The first column in the table represents second term of the polynomial.

In first column first term are variable and last term are constant.

Write all the terms of the first column in the form of sum.

+x-1=x-1

The product of first term of polynomial (3x-1) and second term of polynomial (x-1) is equal to the sum of all remaining terms in this table.

+x²+x²+x²-x-x-x-x+1=3x²-4x+1.

We can also check this by multiplying (3x-1) and (x-1) as

(3x-1)(x-1)=3x(x-1)-1(x-1)

(3x-1)(x-1)=3x(x)-3x(1)-1(x)+1(1)

(3x-1)(x-1)=3x²-3x-x+1

(3x-1)(x-1)=3x²-4x+1

Answer:

If 275 gallon of oil tank costs $400 to fill.

Then 180 gallon of oil tank costs $261.8 to fill.

Step-by-step explanation:

Step 1 of 2

If 275  gallon of oil tank costs $400  to fill.

Then the cost to fill 180  gallon of oil tank can be found by forming a proportion.

Let the required cost be x.

[tex]$$\begin{aligned}\frac{\text { cost }}{\text { Gallons of Gas }} &=\frac{\text { cost }}{\text { Gallons of Gas }} \\\frac{\$ 400}{275} &=\frac{x}{180}\end{aligned}[/tex]

Multiplying both sides by 180 we get,

[tex]$$\begin{aligned}\frac{\$ 400}{275} \times 180 &=\frac{x}{180} \times 180 \\x &=\frac{\$ 400}{55} \times 36 \\x &=\$ 261.8\end{aligned}$$[/tex]

Step 2 of 2

To check if the answer is reasonable, we substitute it back in the formed proportion

[tex]$\frac{\$ 400}{275}=\frac{x}{180}$$[/tex]

Answer: 70%

Step-by-step explanation:

A basket contains:

5 yellow balls

3 blue balls

2 white balls

What would be the probability of randomly picking a ball and the ball not being blue?

So, we can find the probability of picking up a blue ball. Let's do that first.

To calculate the probability of getting a blue ball, we need to divide the number of blue balls by the number of possible balls.

The number of blue balls = 3

The total number of balls = 2 + 3 + 5 = 10 balls

3 blue balls divided by 10 balls = 0.3.

If you multiply 0.3 by 100%, it will give you a probability of finding a blue ball equal to 30%

Now, we just need to find the probability of NOT finding a blue ball. Because we have 30% of finding a blue ball, we just need to subtract 30% from 100%.

100 - 30$ = 70%

The probability of not getting a blue ball is equal to 70%.
