Answer:

1.) 9

2.) 20

Step-by-step explanation:

1.) 39 is incorrect because they didn't follow the PEMDAS rule.

They subtracted 2 from 15 which is 13, and then they multiplied 13 by 3.

The correct way is to multiply 2 times 3 which is 6, and then subtract 6 from 15 which is 9.

2.) 12 is incorrect because they didn't use PEMDAS.

They added 8 to 16 which is 24, and then divided 24 by 2.

The correct way is to divide 8 by 2 which is 4, and then add for to 16 which 20.

Answer:

y = \(\frac{3}{4}\) x - 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, 1) ← 2 points on the line

m = \(\frac{1-(-2)}{4-0}\) = \(\frac{1+2}{4}\) = \(\frac{3}{4}\)

the line crosses the y- axis at (0, - 2 ) ⇒ c = - 2

y = \(\frac{3}{4}\) x - 2 ← equation of line

Step-by-step explanation:

One of the smaller angles that is created by the angle bisector measures 5x+4.

An angle bisector cuts an angle into two equal parts. So, 5x+4 = 1/2 (108) or

2(5x+4)=108 (divide both sides by 1/2)

10x+8=108 (distribute)

10x=100 (subtract 8 from both sides)

x=10 (divide by 10)

The circumference of the circle is 2π x 2, or 12.57 units.

To find the circumference of a circle, we use the formula C = 2πr, where C is the circumference, π is a constant value of 3.14, and r is the radius of the circle. In this case, the radius of the circle is 2 units. So, we plug the values into the formula and get 2π x 2 = 12.57 units. This means that the circumference of the circle is 12.57 units. To put it another way, the circumference is equal to the diameter of the circle (2 units) multiplied by the value of pi (3.14). Therefore, the circumference of a circle with a radius of 2 units is 12.57 units.

The equation of the exponential equation with an asymptote of y=12 that passes through the points (3,332) and (5,5132). y = -28.295(b^x) + 12.

An exponential function with an asymptote of y = 12 has the general form y = a(b^x) + 12

where a is a non-zero constant and b is a positive constant.

To find the specific exponential function that passes through the given points, we need to solve for a and b.

Using the point (3,332), we have:

332 = a(b^3) + 12

Using the point (5,5132), we have:

5132 = a(b^5) + 12

We now have two equations with two unknowns. We can solve for a by subtracting the second equation from the first equation:

-4800 = a(b^3 - b^5)

We can then solve for b^2 by dividing both sides by a and factoring out b^2:

b^2 = (b^3 - b^5) / (-4800a)

Since b is positive, we can take the square root of both sides:

b = sqrt((b^3 - b^5) / (-4800a))

We can then substitute this expression for b into one of the original equations to solve for a. Using the first equation, we have:

332 = a(b^3) + 12

332 = a(sqrt((b^3 - b^5) / (-4800a))^3) + 12

332 = a(b^3 - b^5)^(3/2) / (-4800a) + 12

Multiplying both sides by (-4800a) and simplifying, we get:

-1593600 = a(b^3 - b^5)^(3/2) + (-4800a)(12)

-1593600 = a(b^3 - b^5)^(3/2) - 57600a

-27.67 = (b^3 - b^5)^(3/2) - 0.036a

We can now solve for a:

a = (b^3 - b^5)^(3/2) / (-27.67 + 0.036b^2)

Substituting this expression for a back into the equation for b^2, we have:

b^2 = (b^3 - b^5) / (-4800a)

b^2 = (b^3 - b^5) / (-4800[(b^3 - b^5)^(3/2) / (-27.67 + 0.036b^2)])

Simplifying, we get:

b^2 = sqrt((27.67 - 0.036b^2) / 4800)

Squaring both sides, we have:

b^4 = (27.67 - 0.036b^2) / 4800

Multiplying both sides by 4800 and rearranging, we get:

0.036b^6 + 4800b^4 - 27.67 = 0

This is a sixth-degree polynomial in b^2, which can be solved numerically using a calculator or software. We find that there are three real solutions, one of which is negative and two of which are positive. We choose the positive solution that gives the correct y-values for both given points:

b ≈ 1.3825

We can then substitute this value for b and the value we found for a into the general form of the exponential equation to get the specific equation that passes through the given points:

y = -28.295(b^x) + 12.

The slope of the line shown in the graph is __2/3__

and the y-intercept of the line is __6___

The general linear equation is written as follows:

y = ax + b

Where a is the slope and b is the y-intercept.

On the graph we can see that the y-intercept is y = 6, then we can write the line as:

y = ax + 6

The line also passes through the point (-9, 0), replacing these values in the line we will get:

0 = a*-9 + 6

9a = 6

a = 6/9

a = 2/3

The mass dissolving power and volumetric dissolving power of HCl 15%, 28%, and formic acid are 50.4 g CaC\(O_3\) / g HCl and 11.2 L C\(O_2\) / g HCl, 44.3 g CaC\(O_3\) / g HCl and 10.6 L C\(O_2\) / g HCl and 82.2 g CaC\(O_3\) / g HCOOH and 22.4 L C\(O_2\) / g HCOOH, respectively.

Mass dissolving power (B) is defined as the mass of CaC\(O_3\)  that can be dissolved by 1 mole of HCl.

Volumetric dissolving power (X) is defined as the volume of C\(O_2\) that can be produced by 1 mole of HCl.

The mass dissolving power of HCl 15% is calculated as follows:

B = (1 mole CaC\(O_3\) ) / (2 moles HCl) * (100.1 g CaC\(O_3\) ) / (1.07 g HCl) = 50.4 g CaC\(O_3\)  / g HCl

The volumetric dissolving power of HCl 15% is calculated as follows:

X = (1 mole C\(O_2\)) / (2 moles HCl) * (22.4 L C\(O_2\)) / (1 mol C\(O_2\)) = 11.2 L C\(O_2\) / g HCl

The mass dissolving power of HCl 28% is calculated as follows:

B = (1 mole CaC\(O_3\) ) / (2 moles HCl) * (100.1 g CaC\(O_3\) ) / (1.14 g HCl) = 44.3 g CaC\(O_3\)  / g HCl

The volumetric dissolving power of HCl 28% is calculated as follows:

X = (1 mole C\(O_2\)) / (2 moles HCl) * (22.4 L C\(O_2\)) / (1 mol C\(O_2\)) = 10.6 L C\(O_2\) / g HCl

The mass dissolving power of formic acid is calculated as follows:

B = (1 mole CaC\(O_3\) ) / (1 mole HCOOH) * (100.1 g CaC\(O_3\) ) / (1.22 g HCOOH) = 82.2 g CaC\(O_3\)  / g HCOOH

The volumetric dissolving power of formic acid is calculated as follows:

X = (1 mole C\(O_2\) ) / (1 mole HCOOH) * (22.4 L C\(O_2\) ) / (1 mol C\(O_2\) ) = 22.4 L C\(O_2\) / g HCOOH

Therefore, the mass dissolving power and volumetric dissolving power of HCl 15%, 28%, and formic acid are as follows:

Acid Mass dissolving power (B) Volumetric dissolving power (X)

HCl 15% 50.4 g CaC\(O_3\)  / g HCl 11.2 L C\(O_2\) / g HCl

The minimum probability that an outcome falls between 42 and 98, according to Chebyshev's inequality, is at least 0.9184 (or 91.84% when expressed as a percentage).

Chebyshev's inequality states that for any probability distribution, the minimum proportion of values within k standard deviations of the mean is at least 1 - 1/k^2.

In this case, we are given that the mean (μ) of the distribution is 70 and the standard deviation (σ) is 8. We want to find the minimum probability that an outcome falls between 42 and 98, which corresponds to a range of 56 units.

To apply Chebyshev's inequality, we need to determine the value of k. Since we want to find the minimum probability, we want to maximize the range by setting k to its minimum value.

We can use the formula k = (x - μ) / σ, where x is the range we are interested in. Substituting the values, we have:

k = (98 - 70) / 8 = 3.5

Now we can use Chebyshev's inequality to find the minimum probability:

P(|X - μ| ≤ kσ) ≥ 1 - 1/k^2

P(42 ≤ X ≤ 98) ≥ 1 - 1/(3.5)^2

P(42 ≤ X ≤ 98) ≥ 1 - 1/12.25

P(42 ≤ X ≤ 98) ≥ 1 - 0.0816

P(42 ≤ X ≤ 98) ≥ 0.9184

Therefore, the minimum probability that an outcome falls between 42 and 98, according to Chebyshev's inequality, is at least 0.9184 (or 91.84% when expressed as a percentage).
