ZABC and ZQRS are supplementary angles.
If the measure of ZABC = 140°, what is the
measure of ZQRS?
MZQRS = [?]

Answers

Answer:

m<QRS = 40

Step-by-step explanation:

180 - 140 = 40

The measure of angle m∠QRS which is supplementary to m∠ABC is determined as 40⁰.

What is a supplementary angle?

A supplementary angle is a pair of angles that add up to 180 degrees.

That is to say, if we have two angles and their measures sum up to 180 degrees, then they are supplementary angles. Each angle in a supplementary pair is called the "supplement" of the other angle.

The measure of angle QRS is calculated by applying the following formula as follows;

m∠QRS + m∠ABC = 180 (supplementary angles add up to 180)

m∠QRS + 140 = 180

m∠QRS = 180 - 140

m∠QRS = 40⁰

Thus, the measure of angle m∠QRS which is supplementary to m∠ABC is determined as 40⁰.

The work of a student to solve the equation 3(3y − 8) = 10 + 3y is shown below:

Step 1: 3(3y − 8) = 10 + 3y
Step 2: 6y − 5 = 10 + 3y
Step 3: 3y − 5 = 10
Step 4: 3y = 15
Step 5: y = 5

In which step did the student first make an error and what is the correct step?

Step 2: 9y − 24 = 10 + 3y
Step 2: 6y + 11 = 10 + 4y
Step 3: 6y − 8 = 3(6 + y)
Step 3: 3(3y − 8) = 7 + y

Answers

Step 2 9y - 24 = 10 + 3y because 3 times 3y its not 6y nor is 3 times 8 equal to 5

Answers

The return on his $675,000 investment is 3.57%.

Given that, Dave bought a rental property for $675,000 cash. One year later, he sold it for $700,000.

We need to find the what was the return on his $675,000 investment.

What is the return on investment?

Return on investment or return on costs is a ratio between net income and investment.

Now, return=700,000-675,000=$25000

Return in percentage=25000/700000×100=3.571%

=3.57%

Therefore, the return on his $675,000 investment is 3.57%.

1. Verizon Wireless would like to estimate the proportion of households that use cell phones for their phone service without a land line. A random sample of 150 households was selected and 48 relied strictly on cell phones for their service. Based on the sample, construct a 95% confidence interval for the true proportion of households which rely strictly on cell phones for their phone service.

Answers

Answer:

The 95% confidence interval for the true proportion of households which rely strictly on cell phones for their phone serviceis (0.2453, 0.3947).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

A random sample of 150 households was selected and 48 relied strictly on cell phones for their service.

This means that [tex]n = 150, \pi = \frac{48}{150} = 0.32[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.32 - 1.96\sqrt{\frac{0.32*0.68}{150}} = 0.2453[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.32 + 1.96\sqrt{\frac{0.32*0.68}{150}} = 0.3947[/tex]

The 95% confidence interval for the true proportion of households which rely strictly on cell phones for their phone serviceis (0.2453, 0.3947).

The angles in a triangle always add up to 180. Therefore:

∠A+∠B+∠C=180

(2x-10)+(3x)+(4x+46)=180

2x+3x+4x+46-10=180

9x=180-36

x=144/9

x=16

Let X be the number of red cards observed in these four trials. The mean of X is:

Answers

Answer:

The mean of X is 2

Step-by-step explanation:

Given the data in the question;

set of 10 cards consist of 5 red card and 5 blacks

cards are chosen, replaced and shuffled four times;

number of independent trials n = 4

now, since its is replaced, the probability of getting a red card in each trial will be;

p = 5/10 = 0.5

let X rep the number of red cards observed in the four trials.

the random variable follows binomial distribution where

n = 4 and p = 0.5

so

E(X) = ∑xP( X = x )

E(X) = np

we substitute

E(X) = 4 × 0.5

E(X) = 2

Therefore, The mean of X is 2

Explanation: so a triangle will always equal 180 add 104 19 and 22 and then subtract that by 180 and you get 35 hope this helps if not reply to my comment and I’ll help
Answer: z=35°

Explanation: First find X. All angles of a triangle adds up to 180°. To find x, add up all sides and set it equal to 180. 22+104+x=180. Solve for x. x = 54

A straight Line is 180°. Use x to find y. x+y = 180. Substitute x. 54+y=180 y = 126

To find z, find y + 19 +z = 180. Substitute y. 126+19+z=180. Solve for z. z = 35

Which phyla have well developed nervous system The Brisbane Manufacturing Company produces a single model of a CD player. Each player is sold for $182 with a resulting contribution margin of $71. Brisbane's management is considering a change in its quality control system. Currently, Brisbane spends $42,000 a year to inspect the CD players. An average of 1,900 units turn out to be defective: 1,520 of them are detected in the inspection process and are repaired for $75. If a defective CD player is not identified in the inspection process, the customer who receives it is given a full refund of the purchase price. The proposed quality control system involves the purchase of an x-ray machine for $210,000. The machine would last for five years and would have salvage value at that time of $18,000. Brisbane would also spend $470,000 immediately to train workers to better detect and repair defective units. Annual inspection costs would increase by $25,000. Brisbane expects this new control system to reduce the number of defective units to 400 per year. 350 of these defective units would be detected and repaired at a cost of only $41 per unit. Customers who still receive defective players will be given a refund equal to 120% of the purchase price.Required:a. What is the Year 3 cash flow if Brisbane keeps using its current system?b.
