The Measures Of The Angles Of A Triangle Are Shown In The Figure Below. Solve For X. (7x-12) 60 O Here

Answers

Answer 1

Answer:

x = 6

Step-by-step explanation:

To find x, create an equation and solve for x.

60° + 90° + (7x - 12)° = 180° (sum of triangle theorem)

60 + 90 + 7x - 12 = 180

Add like terms

138 + 7x = 180

7x = 180 - 138

7x = 42

x = 42/7

x = 6

Area is calculated by multiplying the length of a shape by its width. In this case, we could work out the area of this rectangle even if it wasn't on squared paper, just by working out 5cm x 5cm = 25cm² (the shape is not drawn to scale). Hope this helps

In one house, a realtor decorates 4 twin beds and 1 queen bed with a total of 18 pillows.

In another house, she decorates 4 twin beds and 4 queen beds with a total of 36 pillows.

She puts the same number of pillows on each twin bed, and the same number of pillows on each queen bed.

How many pillows does she put on each twin bed?

How many pillows does she put on each queen bed?

Answers

Answer:

The answer would be 3 pillows on each twin bed and 6 pillows on each queen bed.

Step-by-step explanation:

first house:

3 pillows x 4 twin beds = 12 pillows

18 total pillows - 12 twin bed pillows = 6 queen bed pillows

Second house

6 queen bed pillows x 4 queen beds = 24 queen bed pillow

3 twin bed pillows x 4 twin beds = 12 twin bed pillows

24 queen bed pillow + 12 twin bed pillows = 36 total pillows

Answer:

3 pillows on each twin bed and 6 pillows on each queen bed.

A university class has 26 students: 12 are art majors, 9 are history majors, 5 and are nursing majors. The professor is planning to select two of the students for a demonstration. The first student will be selected at random, and then the second student will be selected at random from the remaining students. What is the probability that the first student selected is a history major and the second student is a nursing major?

Answers

Answer:

6.9%.

Step-by-step explanation:

Given that a university class has 26 students: 12 are art majors, 9 are history majors, 5 and are nursing majors, and the professor is planning to select two of the students for a demonstration, where the first student will be selected at random, and then the second student will be selected at random from the remaining students, to determine what is the probability that the first student selected is a history major and the second student is a nursing major the following calculations must be performed:

26 = 100

9 = X

9 x 100/26 = X

900/26 = X

34.61 = X

25 = 100

5 = X

500/25 = X

20 = X

0.2 x 0.3461 = X

0.069 = X

Thus, the probability that the first student selected is a history major and the second student is a nursing major is 6.9%.

6.9%

MADD (Mother's Against Drunk Drivers) wishes to estimate the proportion of adult drivers that have run at least one red light in the last month. A poll is conducted on a simple random sample of adult drivers and it is found that out of 1251 adult drivers, 641 of them have run at least one red light in the last month. You will be finding a 90% confidence interval for the fraction of adult drivers that run at least one red light in the last month.

Required:
Check that the normality assumptions are met?

Answers

Answer:

Normality assumptions are met.

The 90% confidence interval for the proportion of adult drivers that run at least one red light in the last month is (0.4892, 0.5356).

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 poll is conducted on a simple random sample of adult drivers and it is found that out of 1251 adult drivers, 641 of them have run at least one red light in the last month.

This means that [tex]n = 1251, \pi = \frac{641}{1251} = 0.5124[/tex]

Normality assumptions:

We need that: [tex]n\pi \geq 10, n(1-\pi)\geq 10[/tex]

We have that:

[tex]n\pi = 1251*0.5124 = 641[/tex]

[tex]n(1-\pi) = 1261*0.4876 = 610[/tex]

So normality assumptions are met.

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5124 - 1.645\sqrt{\frac{0.5124*0.4876}{1251}} = 0.4892[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5124 + 1.645\sqrt{\frac{0.5124*0.4876}{1251}} = 0.5356[/tex]

The 90% confidence interval for the proportion of adult drivers that run at least one red light in the last month is (0.4892, 0.5356).

This table models function m.

Answers

Answer:

A: The y-intercept of function m is less than that of function n.

Step-by-step explanation:

From the table, we see that when x = 0, m(x) = -6.

This means that the y-intercept of function m is -6.

For the function "n", we are told it passes through (-1, 0) and (0, 2)

We see that at the second coordinate, at x = 0, y = 2.

This means that the y-intercept of the n function is at 2.

Therefore,we conclude that the y-intercept of function m is less than that of function n.
