Order the ratios from least to greatest<br> 16/24, 5 to 12, 6:13, 10:17, 13/28
saul85 [17]

Answer:

5/12, 6/13, 13/28, 10/17, 2/3

Step-by-step explanation:

First, simplify the ones that could be simplified.

2/3, 5 to 12, 6:13, 10:17, 13/28

<em>(okay apparently only the first could be simplified)</em>

<em />

You can look at all of them as fractions

2/3, 5/12, 6/13, 10/17, 13/28

According to the U.S. Census Bureau, 42% of men who worked at home were college graduates. In a sample of $14 women who worked a
Lady bird [3.3K]

Answer:

Step-by-step explanation:

1) The point estimate, p for the proportion of college graduates among women who work at home is

p = x/n

Where

x = number of success = 158

n = number of samples = 514

p = 158/514 = 0.307

2) Confidence interval is written as

Sample proportion ± margin of error

Margin of error = z × √pq/n

Where

z represents the z score corresponding to the confidence level

p = sample proportion. It also means probability of success

q = probability of failure

q = 1 - p

Probability of success, p = 42/100 = 0.42

Probability of failure = 1 - p = 1 - 0.42 = 0.58

To determine the z score, we subtract the confidence level from 100% to get α

α = 1 - 0.8 = 0.2

α/2 = 0.2/2 = 0.1

This is the area in each tail. Since we want the area in the middle, it becomes

1 - 0.1 = 0.9

The z score corresponding to the area on the z table is 1.282. Thus, the z score for a confidence level of 80% is 1.282

Margin of error = 1.282 × √(0.42 × 0.58)/514

Margin of error = 0.028

Therefore, the 80% confidence interval is

0.307 ± 0.028

The lower limit of the confidence interval is

0.307 - 0.028 = 0.279

The upper limit of the confidence interval is

0.307 + 0.028 = 0.335

Therefore, an 80% confidence interval for the proportion of women who work at home is between 0.279 and 0.335

Survey: On free time 90 students like watching TV, 20 like watching TV but not reading, 80 like reading, 40 do not like watching
Dvinal [7]

Answer:

 50 %

Step-by-step explanation:

From the diagram attached,

Percentage of total students that like watching television = [(WnR)/μ]×100......... Equation 1

The number of students that like watching television and reading (WnR) = 70

The total number of students (μ) = 40+20+70+10

The total number of students (μ) = 140

Substitute these values into equation 1

Percentage of total students that like watching television = (70/140)×100

Percentage of total students that like watching television = 1/2(100)

Percentage of total students that like watching television = 50 %

The value of x in all case is

1. The value of x is 2

2. The value of x is 1

3.The value of x is 57

4.The value of x is 93

<h3>What is complementary and supplementary angle?</h3>

If the sum of two angles is 180 degrees then they are said to be b angles, which form a linear angle together. Whereas if the sum of two angles is 90 degrees, then they are said to be complementary angles, and they form a right angle together.

1. As the given angle is 90 degree i.e., complementary angle.

So,

54+10x+16=90

20=10x

x=2

2. 65x-12=43x+10  (Vertically opposite angle)

 22x= 22

x=1

3. 72= x+15  (Vertically opposite angle)

x= 57

4.x+244+23=360  (Complete angle)

 x=93
