what is the area of the rectangle shown on the coordinate plane?​

Answer:

im not sure if this is correct but:

Step-by-step explanation:

4x+18

360= 4x+18

360-18=342

342/4 is 85.5

to check work

(85.5*4) + 18

=360

The value of x that will make the considered parallelogram ABCD a rhombus is 4 units.

Rhombus is a parallelogram whose all sides are of equal lengths.

For this problem, the missing figure is attached below.

We see that the angle between the diagonals is [tex](3x- 12)^\circ[/tex]

It is given that ABCD is a parallelogram.

For ABCD parallelogram to be a rhombus, its diagonals need to be perpendicular to each other.

Perpendicular lines have 90° angle between them.

Thus, we need:

[tex](3x- 12)^\circ = 90^\circ[/tex]

Evaluating value of x:

[tex](3x- 12)^\circ = 90^\circ\\3x - 12 = 90\\\text{Adding 12 on both the sides}\\3x = 102\\\text{Dividing both the sides by 3}\\\\x = 12/3 = 4[/tex]

Thus, the value of x is 4

Answer:

p = 23

q = 18

Step-by-step explanation:

The four interior angles of a square are all 90° each

 4p - 2 = 90

⇒ 4p = 92

⇒ p = 92 ÷ 4

⇒ p = 23

 5q = 90

⇒ q = 90 ÷ 5

⇒ q = 18

Answer:

p=23; q=18.

Step-by-step explanation:

1) m∠(XWZ)=90, then 4p-2=90 and p=23°;

2) m∠(WZY)=90, then 5q=90 and q=18°.

The game field is 350 40 percent for 250 is 100 and 250 plus 100 is 350

Answer:

Step-by-step explanation:

The general equation is y = mx + b

You already have m which is the slope. So the general equation becomes y = -5x + b

The point is meant to find b

x = - 4

y = 7

7 = - 5*-4 + b

7 = 20 + b                         Subtract 20 from  both sides.

7 - 20 = 20-20 + b           Combine

- 13 = b

Answer: y = - 5x - 13

The critical values of Z in this study are given by: Option C: -1.96 and 1.96

There are two hypotheses. First one is called null hypothesis and it is chosen such that it predicts nullity or no change in a thing. It is usually the hypothesis against which we do the test. The hypothesis which we put against null hypothesis is alternate hypothesis.

Null hypothesis is the one which researchers try to disprove.

For this case, we want to know if the two groups of teachers had different levels of job satisfaction.

Suppose that we have:

Then, as the test is for checking if the difference exist, the null hypothesis will deny existence of any difference.

Thus, we get:

The alternate hypothesis creates two regions, on either side as:

[tex]\mu_1 < \mu_2[/tex] and [tex]\mu_1 > \mu_2[/tex]

This is why it is two tailed test.

The level of significance is 5% specified.

Thus, [tex]\alpha = 5\% = 5/100 = 0.05[/tex]

From the critical values table, the critical value(s) of Z for level of significance 0.05 and for two tailed test are: [tex]\pm 1.96[/tex]

Thus, the critical values of Z in this study are given by: Option C: -1.96 and 1.96

Answer:

r≈ 5.9 cm

Step-by-step explanation:

A z-table is also known as the standard normal distribution table. The probability of P(0.75≤ z ≤ 1.25) is 0.121.

A z-table also known as the standard normal distribution table, helps us to know the percentage of values that are below (or to the left of the Distribution) a z-score in the standard normal distribution.

As it is given that the probability and the z-table is given to us, as shown below,

 z          Probability

0.00       0.5000

0.25       0.59871

0.50        0.6915

0.75        0.7734

1.00         0.8413

1.25         0.8944

1.50          0.9332

1.75          0.9599

The following probabilities can be written as:

1.  The probability of P(-1.25)

[tex]P(-z)=1-P(z)\\\\P(-1.25)=1-P(1.25)\\\\P(-1.25)=1-(0.8944)\\\\P(-1.25)=0.1056[/tex]

The probability of P(-1.25) is 0.1056.

2.  The probability of P(-1.25 ≤ z ≤ 0.25)

[tex]P(-1.25\leq z\leq 0.25)=P(0.25)-P(-1.25)\\\\P(-1.25\leq z\leq 0.25)=0.59871-0.1056=0.49311[/tex]

The probability of P(-1.25 ≤ z ≤ 0.25) is 0.49311.

3.  The probability of P(-1.25 ≤ z ≤ 0.75)

[tex]P(-1.25\leq z\leq 0.75)=P(0.75)-P(-1.25)\\\\P(-1.25\leq z\leq 0.75)=0.7734-0.1056=0.6678[/tex]

The probability of P(-1.25 ≤ z ≤ 0.75) is 0.6678.

4.  The probability of P(0.25 ≤ z ≤ 1.25)

[tex]P(0.25 \leq z\leq 1.25)=P(1.25)-P(0.25)\\\\P(0.25\leq z\leq 1.25)=0.8944-0.59871=0.29569[/tex]

The probability of P(0.25 ≤ z ≤ 1.25) is 0.29569.

5.  The probability of P(0.75≤ z ≤ 1.25)

[tex]P(0.75\leq z\leq 1.25)=P(1.25)-P(0.75)\\\\P(0.75\leq z\leq 1.25)=0.8944-0.7734=0.121[/tex]

The probability of P(0.75≤ z ≤ 1.25) is 0.121.
