Step-by-step explanation:

From the question we are told that:

Degree of freedom [tex]df=14[/tex]

Significance Level [tex]\alpha=0.35[/tex]

Generally the expression for critical value t is mathematically given by

  [tex]t_{\alpha,df}[/tex]

  [tex]t_{0.35,14}[/tex]

Therefore From Students T Value Table

 [tex]t_{0.35,14}= 0.3933306[/tex]

 [tex]T-Value (right-tailed): 0.3933306[/tex]

Answer:

Step-by-step explanation:

A couple of different references are used when talking about angles in the x-y coordinate plane. Conventionally, angles are measured CCW from the +x axis of the plane. This is the reference usually used in physics problems involving acceleration, velocity, and displacement.

If the angles refer to bearings on a map, the usual mapping is north = +y, east = +x, and angles are measured CW from north. This is the reference usually used in (flat earth) navigation problems involving airspeed and ground speed.

We cannot tell the intended meaning of "direction angle" here, hence there are two answers. Take your choice.

__

If the angle is measured counterclockwise from the +x direction, the (x, y) coordinates of the vector (137; 235°) are ...

  (x, y) = 137(cos(235°), sin(235°))

  (x, y) = (-78.58, -112.22)

The y-component is -112.22 miles per hour.

__

If the "direction angle" is a bearing measured clockwise from the +y direction, then the x- and y-coordinates are swapped from those listed above.

  (x, y) = (-112.22, -78.58)

The y-component is -78.58 miles per hour.

_____

Additional comment

We say this is "flat earth" navigation because any serious navigation calculation must take into account the Earth's curvature. A path that follows a great circle will not have a constant compass bearing except along the equator or a longitude line.

Answer:

The null hypothesis is [tex]H_0: \mu = 6658[/tex]

Tha alternate hypothesis is [tex]H_a: \mu > 6658[/tex]

The decision rule is that if [tex]t < 1.976[/tex], the null hypothesis is not rejected, that is, there is no evidence to conclude that these households paid more interest than the survey result, and that if [tex]t > 1.976[/tex], the null hypothesis is reject and there is evidence to conclude that these households paid more interest than the survey result.

The test statistic is [tex]t = 1.94[/tex]

As the test statistic of [tex]t = 1.94[/tex] is higher than the critical value of t, it is reasonable to conclude that these households paid more interest than the survey result

Step-by-step explanation:

A recent survey by nerdwallet indicated Americans paid a mean of $6,658 interest on credit card debt in 2017. Test if it is reasonable to conclude that these households paid more interest than the survey result.

At the null hypothesis, we test if they paid the same, that is:

[tex]H_0: \mu = 6658[/tex]

At the alternate hypothesis, we test if they paid more, that is:

[tex]H_a: \mu > 6658[/tex]

Test statistic:

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.

State the decision rule for 0.05 significance level.

Right-tailed test(test if the mean is higher than the value) with 12 - 1 = 11 degrees of freedom, has a critical value of t = 1.976.

So

The decision rule is that if [tex]t < 1.976[/tex], the null hypothesis is not rejected, that is, there is no reasonable evidence to conclude that these households paid more interest than the survey result, and that if [tex]t > 1.976[/tex], the null hypothesis is reject and there is reasonable evidence to conclude that these households paid more interest than the survey result.

6658 is tested at the null hypothesis:

This means that [tex]\mu = 6658[/tex]

Sample mean and standard deviation:

With the given data-set:

Mean of [tex]X = 7163.6[/tex]

Standard deviation of [tex]s = 902.25[/tex]

Sample of 12:

This means that [tex]n = 12[/tex]

Compute the value of the test statistic.

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{7163.6 - 6658}{\frac{902.25}{\sqrt{12}}}[/tex]

[tex]t = 1.94[/tex]

As the test statistic of [tex]t = 1.94[/tex] is higher than the critical value of t, it is reasonable to conclude that these households paid more interest than the survey result

Step-by-step explanation:

6x² + 4x - 10 in factored form is:

2(3x+5)(x-1)

Answer:

Assuming that you actually mean that if [tex](x+2)[/tex] is a factor of [tex]x^{3}+6x^{2}+3x-10[/tex], the answer is yes.

Step-by-step explanation:

We need to do long division of the polynomial to figure out if this is true. I would show it here, but it is extremely difficult to do so. (Maybe someone could help me.) When I factor it, it does not leave a remainder, so this is true.

[tex]x^{3}+6x^{2}+3x-10= (x+2)(x^2+4x-5)[/tex]

Another way one could figure this out is by graphing the equation [tex]x^{3}+6x^{2}+3x-10[/tex] on your graphing calculator or on just a graphing website, lake Desmos. The screenshot below shows the graph.

The polynomial will have a factor of [tex](x-c)[/tex] if the point [tex](0,c)[/tex] exists on the graph. The graph has the following three zeroes.

[tex](0,-2)[/tex], [tex](0, -5)[/tex], and [tex](0,1)[/tex]

As such, it has the three factors [tex](x-(-2))[/tex], [tex](x-(-5))[/tex], and [tex](x-1)[/tex].

Since [tex](x-(-2)=(x+2)[/tex], it is a factor of the polynomial.

Answer:

1150 sq cm.

Step-by-step explanation:

22*45+20*8= 1150 sq cm.

Answer: 1150 cm^2

Step-by-step explanation:

find the area of the rectangle above the dotted line and the area of the one below the dotted line, then add those areas together

so for the rectangle above the area would be 22 * 45 = 990 cm^2

for the lower one the area is 20 * 8 = 160 cm ^2

now add those two together

990 + 160 = 1150

so the total area of the figure would be 1150 cm^2

5. x = 31

6. x = 34

Step-by-step explanation:

4. vertical angles

- 36/6 = 6

5. supplementary angles

180 - 56 = 124

124/4 = 31

6. complementary angle

90 - 22 = 68

68/2 = 34

Answer:

4. x = 6°

5. x = 31°

6. x = 34°

Step-by-step explanation:

4. Vertical Angles theorem states that the two opposite angles formed by 2 intersecting lines are congruent.

6x = 36°

x = 36 / 6

x = 6°

5.

180° - 56° = 4x

124° = 4x

x = 31°

6.

90° - 22° = 2x

68° = 2x

x = 34°

Test statistic = - 0.851063

- 2.520463

Step-by-step explanation:

H0 : μ ≥ 15

H1 : μ < 15

Sample mean, xbar = 14.5

Sample standard deviation, s = 4.7

Sample size = 64

Teat statistic :

(xbar - μ) ÷ (s/√(n))

(14.5 - 15) ÷ (4.7/√(64))

= - 0.851063

The critical value at α = 0.05

Using the T - distribution :

Degree of freedom, df = 64 - 1 = 63

Tcritical(0.05, 63) = 1.6694

Test statistic - critical value

-0.851063 - 1.6694

= - 2.520463

[tex]\boxed {\boxed {\sf 29.25 \ inches}}[/tex]

Step-by-step explanation:

Since we are given the central angle in radians, we should use the following formula for the arc length.

[tex]s= \theta r[/tex]

Where s is the arc length, θ is the angle in radians, and r is the radius.

We know this circle has a radius of 9 inches and the central angle is 3.25 radians.

Substitute the values into the formula

[tex]s= (3.25)( 9 \ in)[/tex]

Multiply.

[tex]s= 29.25 \ in[/tex]

The arc length is 29.25 inches.

Step-by-step explanation:

Because all of those diagonals are equal to each other. So that would mean those diagonals are equal in legnth.

BD is perpendicular to AC Because; all of those diagonals are equal to each other that would mean those diagonals are equal in length.

That quadrilateral in which opposite sides are parallel is called a parallelogram.

Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

Remember that the parallelogram in which adjacent sides are perpendicular to each other is called a rectangle.

The diagonals of the parallelogram are perpendicular to each other and they cut each other in half( thus, they're perpendicular bisector of each other).

BD is perpendicular to AC Because; all of those diagonals are equal to each other that would mean those diagonals are equal in length.

Answer:

I will have to work 11 hours to take my parents to a $ 120 cost dinner, and I will have $ 1 left in return.

If I wanted to tip 15%, I would have to work 13 hours and have $ 5 left over.

In turn, to determine the money generated from an indeterminate number of hours worked, the applicable formula would be 11X = Y, where Y is the money generated and X is the number of hours worked.

Step-by-step explanation:

Since I have just gotten my first job, and I have decided I want to take my parents out for dinner to celebrate and I have anticipated it will cost approximately $ 120 for the three of us to go out for dinner, and at my job, I make an hourly wage of $ 11, to determine how many hours would I need to work to pay for the dinner, and what if I wanted to add a 15% tip, and determine if my strategy could also allow me to find out how much money and or made for any number of hours, the following calculations must be performed:

120/11 = X

10.9 = X

11 x 11 = 121

Therefore, I will have to work 11 hours to take my parents to a $ 120 cost dinner, and I will have $ 1 left in return.

(120 x 1.15) / 11 = X

138/11 = X

12.54 = X

11 x 13 = 143

Therefore, if I wanted to tip 15%, I would have to work 13 hours and have $ 5 left over.

In turn, to determine the money generated from an indeterminate number of hours worked, the applicable formula would be 11X = Y, where Y is the money generated and X is the number of hours worked.
