Point U is located at (1,-4) on the coordinate plane. Point U is reflected on

-axis to create point U'. What ordered pair describes the location of U'?

Answers

Given :

A point U located at (1,-4) on the coordinate plane.

To Find :

The reflection of point U on x-axis.

Solution :

Reflection of any point ( h , k ) on x-axis is ( h , - k ) .

So , the reflection of point U i.e ( 1 , -4 ) is ( 1 , 4 ) .

Therefore , the ordered pair describes the location of U' is ( 1 , 4 ).

Hence , this is the required solution .

Use the map to find the distance between Brookline and Davenport to the nearest tenth

Answers

Answer:

8.5

Step-by-step explanation:

The distance between Brookline(8, 2) and Davenport(5, 10) can be calculated using the distance formula given as [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y1)^2} [/tex].

Let,

[tex] Brookline(8, 2) = (x_1, y_1) [/tex]

[tex] Davenport(5, 10) = (x_2, y_2) [/tex]

[tex] d = \sqrt{(5 - 8)^2 + (10 - 2)^2} [/tex]

[tex] d = \sqrt{(-3)^2 + (8)^2} [/tex]

[tex] d = \sqrt{9 + 64} = \sqrt{73} [/tex]

[tex] d = 8.5 [/tex] (nearest tenth)

6. Ray BD bisects ZABC so that
mZDBC = x + 6 and
mZABD = 2x - 12. What is x?

Answers

Answer:

See below

Step-by-step explanation:

2......................

∠PQR and ∠RQS are supplementary, which add up 180°

∠PQR = 3x - 5∠RQS = x + 1

Sum:

3x - 5 + x + 1 = 1804x - 4 = 1804x = 184x = 46°

3......................

∠PQR = 3x - 5 = 3*46° - 5° = 138° - 5° = 133°

4......................

From the picture and the value of x we got above:

∠RQS = x + 1 = 46 + 1= 47°

QT bisects ∠RQS and we get two equal angles

Each will measure:

47°/2 = 23.5°

5......................

LM = 5, LN = 17, MN = ?

If L is between M and N, then

MN = LM + LN = 5 + 17 = 22

M is between L and N, then

MN = LN - LM = 17 - 5 = 12

5......................

Ray BD bisects ∠ABC, then formed angles are equal:

m∠DBC = x + 6 m∠ABD = 2x - 12

m∠DBC = m∠ABD

x + 6 = 2x - 122x - x =6 + 12x = 18°

Find the area of the parallelogram shown below.60 squ

Answers

Answer:

A

Step-by-step explanation:

The area for a parallelogram is given by the formula:

[tex]A=bh[/tex]

Where b is the base length and h is the vertical height.

The base length is 6 and the height is 10 (if you flip the figure 90 degrees). So:

[tex]A=6(10)[/tex]

Multiply:

[tex]A=60\text{ units}^2[/tex]

A local brewery produces three premium lagers named Half Pint, XXX, and Dark Night. Of its premium lagers, they bottle 40% Half Pint, 40% XXX, and 20% Dark Night lagers. In a marketing test of a sample of consumers, 27 preferred the Half Pint lager, 29 preferred the XXX lager, and 24 preferred the Dark Night lager. Using a chi-square goodness-of-fit test, decide to retain or reject the null hypothesis that production of the premium lagers matches these consumer preferences using a 0.05 level of significance. State the value of the test statistic. (Round your answer to two decimal places.) $ \chi_{obt}^2 $

Answers

Answer:

reject the null hypothesis

Step-by-step explanation:

Total observation = 27+49+24 = 100

Expected Frequency :

Half Pint = 100 × 0.4 = 40

XXX = 100 × 0.4 = 40

Dark night = 100 × 0.2 = 20

The Chi-square goodness-of-fit test can be computed as follows:

             Observed              Expected                  [tex]X^2 = \dfrac{(O- E)^2}{E}[/tex]

            Frequency(O)         Frequency (E)

Half-       27                            40                                 4.225      

Pint

XXX       29                           40                                  3.025

Dark-       24                          20                                  0.8

night

Total      100                         100                                 8.05

The test statistics [tex]X^2[/tex] = 8.05

8.05

degree of freedom = n -1

degree of freedom =  3 - 1

degree of freedom =  2

The p-value can be computed by using the EXCEL FORMULA (=CHIDIST(8.05,2)

p-value = 0.01786

Since the p-value is less than the level of significance, we reject the null hypothesis

Also using the critical value approach from the EXCEL FUNCTION;

critical chi-square  (=CHIINV(0.05,2) = 5.99

[tex]X^2 > 5.99[/tex], therefore, we reject the null hypothesis

An observer (O) spots a plane flying at a 55° angle to his horizontal line of sight. If the plane is flying at an altitude of 21,000 ft., what is the distance (x) from the plane (P) to the observer (O)?

Answers

Answer:

Step-by-step explanation:

The givens form a right triangle. The operational definition is The opposite over the hypotenuse, where the hypotenuse is the unknown.

sin(x) = 21000/hypotenuse

sin(55) = 21000 / hypotenuse

hypotenuse * sin(55) = 21000

hypotenuse = 21000/sin(55)

hypotenuse = 25636 feet.= 26000 feet rounded.

The answer does make sense. The hypotenuse is larger than the given height.
