Mario left 65 miles to reach his goal and m + 65 = 130 is the equation to show how many miles Mario has left to run this month to reach his goal

Two or more expressions with an Equal sign is called as Equation.

Given that the Mario set a goal to run 130 miles this month to prepare for a marathon.

He has run 65 miles in this month.

We need to find the equation to show how many miles Mario has left to run this month to reach his goal.

m+65=130

We can find the left out distance in miles.

Subtract 65 from both sides.

m=130-65

m=65

Hence, m + 65 = 130 is the equation to show how many miles Mario has left to run this month to reach his goal and Mario left 65 miles to reach his goal.

it is true that  0.5% of 200 is 10.

True.

To find 0.5% of a number, we need to multiply the number by 0.5/100, which can be simplified to 5/100 or 1/20. This is because "percent" means "per hundred", so 0.5% is equivalent to 0.5 per 100 or 0.5/100.

Multiplying the number by 5/100 is the same as multiplying it by 0.5/100, so it will give us the correct result.

For example, if we want to find 0.5% of 200, we can multiply 200 by 5/100 or 0.5/100:

\(0.5% of 200 = 200 \times 5/100 = 10\)

Therefore, it is true that  0.5% of 200 is 10.

To find the probability of a range of values within the standard normal distribution, we need to calculate the area under the curve between two z-scores. In this case, we need to find P(-2.50 < z < 1.50).

The standard normal distribution is a bell-shaped curve with a mean of 0 and a standard deviation of 1. It is often used in statistical calculations and hypothesis testing. To find the probability between two z-scores, we calculate the area under the curve within that range.

In this problem, we want to find the probability between z = -2.50 and z = 1.50. We can use a standard normal distribution table or statistical software to find the corresponding probabilities. The table or software provides the area under the curve for different z-scores.

First, we find the probability associated with z = -2.50, which is the area to the left of -2.50 on the standard normal distribution curve. Similarly, we find the probability associated with z = 1.50, which is the area to the left of 1.50 on the curve. Subtracting the two probabilities gives us the desired probability between -2.50 and 1.50.

By using the standard normal distribution table or software, we can find the probabilities associated with z = -2.50 and z = 1.50. Then, subtracting these probabilities will give us the probability between -2.50 and 1.50. The resulting probability represents the area under the curve within that range, indicating the likelihood of a random variable falling within that interval.

$25000

Step-by-step explanation:

100% - 34% = 66%

We know that

66% = $16,500

We have to find 1%

16500 divided by 66 = $250

Then we have to find the 34%

250 times 34 = $8500

Then we add both numbers to find their previous year's revenue

$16500 + $8500 = $25000

So, their previous year's revenue is $25000

Answer and Step-by-step explanation:

In the first figure, Angle y is equal to 90 by the vertical angles theorem.

Then, you would do 180 0 90, divided by 2 to find x.

180 - 90 = 90, divided by 2 = 45.

Angle x is equal to 45 in the first figure.

In the second figure, Angle y is equal to 80, since the sides are congruent, meaning the triangle is an isosceles triangle.

So, to find the unknown angle, we add 80 and y together, and subtract it from 180.

180 - (80 + 80) = 180 - 160 = 20

Angle of measurement of 20 is supplementary to angle x.

These add up to 180 when combined.

180 - 20 = x

160 = x.

Angle x is equal to 160 in the second figure.

#teamtrees #PAW (Plant And Water)

for the first triangle:

y=90, vertically opposite angles

x=45, steps: 180-90= 90

                         90/2=45

second triangle:

y=50, isosceles triangle: 2 equal sides.

x=100, 180-50-50=80

                 180-80=100, both angles on the same straight line.

The equation of the horizontal line through (-7,-3) is \(y = x - 3\).and this can be determined by using the two-point form of a line.

Given :

The line is horizontal and passes through (-7,-3).

The following steps can be used in order to determine the equation of a line that passes through (-7,-3):

Step 1 - According to the given data, the line is horizontal which means it is parallel to the x-axis.

Step 2 - So, the horizontal line also passes through (0,-3).

Step 3 - So, the equation of a line that passes through the points (-7,-3) and (0,-3) is:

\(\dfrac{y+3}{x-0}=\dfrac{-3+3}{-7-0}\)

Step 4 - Simplify the above expression.

\(y = x - 3\)

So, the equation of the horizontal line through (-7,-3) is \(y = x - 3\).

The point of maximum growth rate for the function is (1.4, 15)

From the question, we have the following parameters that can be used in our computation:

f(x) = 30/(1 + 2e⁻⁰.⁵ˣ)

A logistic function is represented as

f(x) = M/(1 + ceⁿᵇ)

And the point of maximum growth rate for the function is calculated as

x = ln(c)/n

y = M/2

In this case,

M = 30, c = 2 and n = -0.5

Substitute the known values in the above equation, so, we have the following representation

x = ln(2)/(0.5) = 1.4

y = 30/2 = 15

The equation of the line that is perpendicular to 2x-3y=6 and passes through the point (12,24) in slope-intercept form is y = -1.49x + 41.88.

Given a line and a point, find a line perpendicular to the given line, through the given point:2x - 3y = 6Divide both sides by -3 to make y the subject:2x/-3 - 6/-3 = y0.67 x - 2 = y

Therefore, the slope is 0.67. Find the slope of a line perpendicular to the line using the negative reciprocal of the slope of the given line.

Therefore, the slope of a line perpendicular to this line will be -1.49.Using the point-slope formula, y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope that was determined above.(y - 24) = -1.49(x - 12)

Substitute the slope-intercept formula y = mx + b and solve for the y-intercept. y - 24 = -1.49x + 17.88y = -1.49x + 41.88

Therefore, the equation of the line that is perpendicular to 2x-3y=6 and passes through the point (12,24) in slope-intercept form is y = -1.49x + 41.88.

0 ≤ x ≤ 4 and 0 ≤ y ≤ 3, we have:  

∬S z dS = ∫0^3 ∫0^4 (2/3 (x^(3/2) + y^(3/2))) √(2/3 x + 2/3 y + 1) dx dy

This integral can be evaluated using numerical methods.

To evaluate the surface integral, we first need to parameterize the surface S. We can use the parameterization:

r(x,y) = <x, y, 2/3 (x^(3/2) + y^(3/2))>, where 0 ≤ x ≤ 4 and 0 ≤ y ≤ 3.

Then, the surface integral of a scalar function f(x,y,z) over S can be calculated using the formula:

∬S f(x,y,z) dS = ∬D f(r(x,y)) ||r_x x r_y|| dA

where D is the region in the xy-plane that is mapped onto the surface S by the parameterization r(x,y), and ||r_x x r_y|| is the magnitude of the cross product of the partial derivatives of r with respect to x and y.

In this case, f(x,y,z) = z = 2/3 (x^(3/2) + y^(3/2)), and r(x,y) = <x, y, 2/3 (x^(3/2) + y^(3/2))>. We can calculate the partial derivatives of r with respect to x and y:

r_x = <1, 0, 2/3 (3/2 x^(1/2))>

r_y = <0, 1, 2/3 (3/2 y^(1/2))>

Taking the cross product of these vectors, we get:

r_x x r_y = <-2/3 (3/2 x^(1/2)), -2/3 (3/2 y^(1/2)), 1>

The magnitude of this vector is:

||r_x x r_y|| = √(4/9 (3/2 x^(1/2))^2 + 4/9 (3/2 y^(1/2))^2 + 1) = √(2/3 x + 2/3 y + 1)

So the surface integral becomes:

∬S z dS = ∬D (2/3 (x^(3/2) + y^(3/2))) √(2/3 x + 2/3 y + 1) dA

To evaluate this integral, we can use a double integral over the region D in the xy-plane. Since 0 ≤ x ≤ 4 and 0 ≤ y ≤ 3, we have:

∬S z dS = ∫0^3 ∫0^4 (2/3 (x^(3/2) + y^(3/2))) √(2/3 x + 2/3 y + 1) dx dy
