The equation of the straight line in slope - intercept form that

is perpendicular to the given line and passes through the point (0, 9) is -

y = 6x + 9.

The general equation of a straight line is -

y = mx + c

where -

{m} is the slope of the line.

{c} is the {y} - intercept.

Given is that the equation of a straight line as -

2x + 12y = - 1

Assume that the equation of the straight line in slope - intercept form as

y = mx + c

Now, the given straight line is perpendicular to the given line. So, we can write the slope as -

{m} = -1/(-1/6)

{m} = 6

For the {y} intercept, we can write -

{c} = 9

So, we can write the equation of the straight line in slope - intercept form that is perpendicular to the given line and passes through the point (0, 9) is -

y = 6x + 9

Therefore, the equation of the straight line in slope - intercept form that

is perpendicular to the given line and passes through the point (0, 9) is -

y = 6x + 9.

Answer:

191.67 feets

Step-by-step explanation:

From. The attached picture :

Height x can be obtained using trigonometry :

Tan 22 = x / 200

0.4040262 = x / 200

x = 0.4040262 * 200

x = 80.805245 feets

For height, y :

Tan 29 = x / 200

0.5543090 = x / 200

y = 0.5543090 * 200

y = 110.86181 feets

Building height = x + y

Building height = 80.805245 + 110.86181 = 191.67 feets

The linear function q(x) = -3x + 1 is graphed and attached

The graph of the linear function is a straight line graph and the table of values used in making the plot is calculated as follows

For x = -20,  q(x) = -3 * -20 + 1 = 61

For x = -10,  q(x) = -3 * -10 + 1 = 31

For x = 0,  q(x) = -3 * 0 + 1 = 1

Answer:

a) 0.0885 = 8.85% probability that the mean annual return on common stocks over the next 40 years will exceed 13%.

b) 0.4129 = 41.29% probability that the mean return will be less than 8%

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean 8.7% and standard deviation 20.2%.

This means that [tex]\mu = 8.7, \sigma = 20.2[/tex]

40 years:

This means that [tex]n = 40, s = \frac{20.2}{\sqrt{40}}[/tex]

(a) What is the probability (assuming that the past pattern of variation continues) that the mean annual return on common stocks over the next 40 years will exceed 13%?

This is 1 subtracted by the pvalue of Z when X = 13. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{13 - 8.7}{\frac{20.2}{\sqrt{40}}}[/tex]

[tex]Z = 1.35[/tex]

[tex]Z = 1.35[/tex] has a pvalue of 0.9115

1 - 0.9115 = 0.0885

0.0885 = 8.85% probability that the mean annual return on common stocks over the next 40 years will exceed 13%.

(b) What is the probability that the mean return will be less than 8%?

This is the pvalue of Z when X = 8. So

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{8 - 8.7}{\frac{20.2}{\sqrt{40}}}[/tex]

[tex]Z = -0.22[/tex]

[tex]Z = -0.22[/tex] has a pvalue of 0.4129

0.4129 = 41.29% probability that the mean return will be less than 8%

Answer: MW = CD

Explanation: It would be this way because if you wrote the triangles out, MW would be in the same place as CD, making them corresponding.

The following segments are corresponding parts of the congruent triangles.

segment MT ≅ segment CA

segment TW ≅ segment AD

segment MW ≅ segment CD

Two triangles are said to be congruent if pairs of their corresponding sides and their corresponding angles are equal. They are of the same shape and size.

Given that

Triangle MTW = Triangle CAD

If two triangles are congruent then the corresponding sides and corresponding angles are congruent.

∴ segment MT ≅ segment CA

{corresponding parts of the congruent triangles}

segment TW ≅ segment AD

{corresponding parts of the congruent triangles}

segment MW ≅ segment CD

1.

Given that,

L = 18 in , w = 20 in , h = 16 in

The surface area of the box is given by :

SA= 2lw + 2lh + 2wh

Put all the values,

SA= 2lw + 2lh + 2wh

= 2(lw+lh+wh)

= 2(18(20)+18(16)+20(16))

= 2 (968)

= 1936 in²

2.

L= 10.5 in , W= 15.5 in , H= 20 in

The surface area of the box is given by :

SA= 2lw + 2lh + 2wh

Put all the values,

SA= 2lw + 2lh + 2wh

= 2(lw+lh+wh)

= 2(10.5(15.5)+10.5(20)+15.5(20))

= 2 (682.75)

= 1365.5 in²

Hence, this is the required solution.

Dirk will make 70 pars or better.

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that During the first several rounds of a golfing league, Dirk made par or better on 42 out of 90 holes.

Out of 90 holes, Dirk made par or better on 42 holes.

At this rate, Out of 1 hole, Dirk made par or better on (42/90) holes.

Then, Out of 150 holes, Dirk will make par or better on -

(42/90 x 150) holes

(42/90 x 150)

Answer:

  D.  none of the above

Step-by-step explanation:

The sides are different lengths and not at right angles, so the figure is not a rhombus or a rectangle. It is "none of the above."

__

Counting grid squares in the attached figure, we see that one side is the diagonal of a 2×3 rectangle, and the adjacent side is the diagonal of a 1×3 rectangle. This tells you two things: (a) the sides are different length, (b) they are not at right angles to each other. (If the sides were perpendicular, the slopes of the segments would be opposite reciprocals.)

Answer:

304.75 inches

Step-by-step explanation:

Total distance = 101 feet 7 inches

Recall :

1 Feet = 12 inches

Total distance in inches = (101 * 12) + 7 = 1219 inches

Perimeter of square = 1219

Sides of a square are always equal

Number of sides = 4

Hence, length of each side = 1219 inches / 4 = 304.75 inches

Answer:

B) No, because the p-value is greater than any reasonable significance level

Step-by-step explanation:

H-null: p = 0.41

H-alt: p =/= 0.41

1 proportion Z test

On a calculator: stat + tests + 5

   p: .41

   x: 245

   n: 600

   prop: =/= p

This gives a p-value = .934

(standard significance level is .05, so this p-value is much larger)

fail to reject H-null

If the p-value is much larger than 0.41 then the null hypothesis is rejected. Then the correct option is B.

In null hypotheses, there is no relationship between the two phenomenons under the assumption or it is not associated with the group. And in alternative hypotheses, there is a relationship between the two chosen unknowns.

A research organization reported that 41 percent of adults who were asked to describe their day responded that they were having a good day rather than a typical day or a bad day.

To investigate whether the percentage would be different for high school students, 600 high school students were randomly selected.

When asked to describe their day, 245 students reported that they were having a good day rather than a typical day or a bad day.

Null hypotheses

p = 0.41

Alternative hypotheses

p ≠ 0.41

The p-value will be given as

p-value = 0.934

The p-value is much larger than p.

[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex]

[tex]15^\circ+m\angle B+120^\circ=180^\circ[/tex]

[tex]m\angle B+135^\circ=180^\circ[/tex]

[tex]m\angle B=180^\circ-135^\circ[/tex]

[tex]m\angle B=45^\circ[/tex]

According to the Law of sines,

[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

Using Law of sines, we get

[tex]\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

[tex]\dfrac{3}{\sin 45^\circ}=\dfrac{c}{\sin 120^\circ}[/tex]

[tex]\dfrac{3}{\dfrac{1}{\sqrt{2}}}=\dfrac{c}{\dfrac{\sqrt{3}}{2}}[/tex]
