Answer:

A. Slope = -³/2

B. y = -³/2x - 6

C. ³/2x + y = -6

Step-by-step explanation:

A. Slope of the line would be the negative reciprocal of the slope of 2x - 3y = 12, which is written in standard form. Rewrite in slope-intercept form, y = mx + b, where m = slope.

Thus:

2x - 3y = 12

-3y = -2x + 12

y = -2x/-3 + 12/-3

y = ⅔x - 4

The slope of 2x - 3y = 12 is therefore ⅔.

The slope of the line perpendicular to 2x - 3y = 12 would be the negative reciprocal of its slope, ⅔ which is:

-³/2

Therefore, the slope of the line perpendicular to 2x - 3y = 12 is -³/2

B. To find the equation of the line in slope-intercept form, first find the equation in point-slope form using the point given (-6, 3) and slope of the line, -³/2.

Substitute a = -6, b = 3, and m = -³/2 into y - b = m(x - a).

Thus:

y - 3 = -³/2(x - (-6))

y - 3 = -³/2(x + 6)

Rewrite in slope-intercept form, y = mx + b

Multiply both sides by 2

2(y - 3) = -3(x + 6)

2y - 6 = -3x - 18

2y = -3x - 18 + 6

2y = -3x - 12

y = -3x/2 - 12/2

y = -³/2x - 6

C. Rewrite y = -³/2x - 6 in standard form.

y = -³/2x - 6

³/2x + y = -6

Answer:

Time=(Distance/Speed)

Time=550/100=5.5hr

Answer:

144

Step-by-step explanation:

A square room has all sides the same length

the perimeter is the length of the sides (which are the same length) therefore dividing it by 4 to get the length of 1 side multiplied by itself will give us the area to be covered.

The x-intercept is at (∞, 0)

The y intercept is (0, 1)

The x-intercept of a graph occurs at the point where y = 0

Given the equation y =  5^x

If y = 0

5^x = 0

xln5 = ln 0

x = ln0/ln5

x = ∞

The x-intercept is at (∞, 0)

y-intercept

The y-intercept occurs at the point where x = 0

y = 5^0

y = 1

Hence the y intercept is (0, 1)

The number of gallons of liquid that Courtney bought is 2 gallons.

Measurement is the method of comparing the properties of a quantity or object using a standard quantity.

Measurement is essential to determine the quantity of any object.

Given that,

Amount of milk bought = 2 quarts

Amount of orange juice bought = 4 quarts

Amount of apple juice bought = 2 quarts

Total amount of liquid bought = 2 + 4 + 2 = 8 quarts

We have the conversion,

1 quart of liquid = 0.25 gallon of liquid

Total amount of liquid bought in gallons = 8 × 0.25 = 2 gallons

Hence the total amount of liquid bought is 8 gallons.

With the random sampling method, every item in the population has an equal chance of being chosen for the sample. Consequently, the process of chance sampling is another name for it.

The population mean's likelihood to differ from a sample mean is indicated by the standard error of the mean, or simply standard error. It reveals how much the sample mean would change if a study were to be repeated with fresh samples drawn from a single population.

Therefore, if the impacts of the random changes are more pronounced, the standard error of the mean will be greater; conversely, if there are no random charges, the standard error of the mean will be zero. The formula for the mean's standard error is: M=N.

The sample data, test type, and sampling distribution of the test statistic under the null hypothesis are used to determine the p-value (lower-tailed test, upper-tailed test, or two-sided test). The formula for calculating the p-value for a lower-tailed test is: p-value = P(TS ts | H 0 is true) = cdf (ts).

Answer:

The suggestion proposed considering special cases, so that’s what we’ll do.

One special case we could consider is when x=0. If h=r, then we have a hemisphere. You may have learnt that the surface area of a sphere is 4πr2, so the answer in this case is 2πr2. Likewise, we can consider the most extreme cases: when h=2r, we get an area of 4πr2 (the entire sphere), and when h=0, we get zero area.

So if we do manage to get a general formula, we will be able to check it in these special cases.

Another possible idea when x=0 is to consider what happens when h is very small. In this case, the surface area looks a lot like a circle, but the radius of the circle does not seem particularly easy to work out, so maybe we’ll leave this one for a moment. (There are things we can do to approximate the radius using more advanced techniques, but they are currently beyond us.)

Another thing we could consider is the situation where h is very small. Then the part of the sphere between the planes looks very much like the frustum of a cone, and we know how to find the (surface) area of such a shape – see Cones.

If we recall our answer from that problem, we find the formulae for the surface area

π(R+r)s=π(R+r)hcosθ=π(R2−r2)sinθ.

Here, R is the radius of the base of the frustum, r is the radius of the top, h is the perpendicular height, s is the slant length and θ is the angle the slant makes with the vertical.

Answer:

0.8746 = 87.46% probability of at least 6 failures in 7 trials.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

7 trials

This means that [tex]n = 7[/tex]

The probability of success in any trial is 9%​?

So the probability of a failure is 100 - 9 = 91%, which means that [tex]p = 0.91[/tex]

Probability of at least 6 failures in 7 trials?

This is:

[tex]P(X \geq 6) = P(X = 6) + P(X = 7)[/tex]

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 6) = C_{7,6}.(0.91)^{6}.(0.09)^{1} = 0.3578[/tex]

[tex]P(X = 7) = C_{7,7}.(0.91)^{7}.(0.09)^{0} = 0.5168[/tex]

[tex]P(X \geq 6) = P(X = 6) + P(X = 7) = 0.3578 + 0.5168 = 0.8746[/tex]

0.8746 = 87.46% probability of at least 6 failures in 7 trials.

Answer:

m = -22

Step-by-step explanation:

Formula for parabola in it's vertex form is given by;

y = a(x - h)² + k

Where (h, k) is the coordinate of the vertex.

We are told that vertex is at (-6, 6) and the roots are at 10 and m.

Thus;

y = a(x - (-6))² + 6

y = a(x + 6)² + 6

Since 10 is a root, thus;

0 = a(10 + 6)² + 6

-6 = 256a

a = -6/256

a = -3/128

Thus,the equation is;

y = (-3/128)(x + 6)² + 6

Since m is a root, then;

0 = (-3/128)(m + 6)² + 6

-6 = (-3/128)(m + 6)²

Rearranging, we have;

128 × 6/3 = (m + 6)²

256 = m² + 12m + 36

m² + 12m - 256 + 36 = 0

m² + 12m - 220 = 0

Using quadratic formula, we have;

m = 10 or -22

Step-by-step explanation:

The slope of a line is obtained thus :

Slope = Rise / Run

Rise = (x2 - x1)

Run = (y2 - y1)

x2 = 3 ; x1 = 0

y1 = - 20 ; y2 = - 20

Slope = (-20 - (-20)) / (3 - 0)

Slope = (-20 + 20) / 3

Slope = 0 / 3

Slope = 0

Hence, the slope or rate of change = 0
