43.586 rounded to the nearest tenth is 43.6, nearest hundredth is 43.59 and nearest ones is 44.

FURTHER EXPLANATION

Place Values

Every digit in a number is assigned a place value. The place value determines the value or size of the digit based on its position in the number. In decimal numbers, the numbers to the left of the decimal point are the whole part and the numbers appearing after the decimal point is the decimal part.

Example: 12.3456

The place values of the digits in the given example are as follows:

1 – tens (10)

2 – ones (2)

3 – tenths (0.3)

4 – hundredths (0.04)

5 – thousandths (0.005)

6 – ten thousandths (0.0006)

Adding the values in the expanded form will give the number:

10 + 2 + 0.3 + 0.04 + 0.005 + 0.0006 = 12.3456

Rounding Off Rules

Sometimes numbers have to expressed with fewer place values or decimal places. To find out what the rounded number will be, a set of rules are followed to standardize the rounding off:

1. If the digit to be rounded is followed by a digit that is less than 5 (0,1,2,3,4), the digit will be unchanged and the numbers after it are dropped.

Example: 2.344 rounded to the nearest tenth is 2.3

2. If the digit to be rounded is followed by a digit greater than or equal to 5, the last digit must be increased by 1 and the succeeding digits are dropped.

Example: 4.584 rounded to the nearest tenth is 4.6

Some Important Terms 

When a digit is to be"rounded to the nearest tenths", it means that the resulting number will have one decimal place.

"Rounded to the nearest hundredths" means the rounded number will have two decimal places.

For the given number 43.586, the place values of the digits are as follows:

4 – tens

3 – ones

5 – tenths

7 - hundredths

8 – thousandths

6 – ten thousandths

Rounding to the nearest tenths 

43.586 will become 43.6

The digit in the tenths place is 5. It is immediately followed by 8. 8 is greater than 5 so the last digit will be increased.

Rounding to the nearest hundredths

43.586 will become 43.59

8 is the digit in the hundredths place. It is followed by 6 which is greater than 5. Therefore, add 1 to 8 and it becomes 43.59.

Rounding to the nearest ones

43.586 will become 44

The digit with the ones place value is 3. It is succeeded by 5 so the last digit 3 must be increased by 1 becoming 44.

6. A hospital needs a supply of an expensive medicine. Company A has the most

Anton [14]

We are required to find the total milligrams if medicine the hospital can get from the three companies.

The total quantity of medicine the hospital can get from the three companies is 2.75 milligrams

There are there companies:

Company A

Company B

Company C

Company A = 1.3 milligrams

Company A is 0.9 milligrams more than Company C's

A = 0.9 + C

1.3 = 0.9 + C

1.3 - 0.9 = C

0.4 = C

C = 0.4 milligrams

Company A is also twice the difference between the weight of

Company B's supply and Company C's

A = 2(B - C)

1.3 = 2(B - 0.4)

1.3 = 2B - 0.8

1.3 + 0.8 = 2B

2.1 = 2B

Divide both sides by 2

B = 2.1/2

B = 1.05 milligrams

Therefore,

A + B + C

= 1.3 + 1.05 + 0.4

= 2.75 milligrams

Find the annual interest rate paid on this loan:

tatyana61 [14]

$75/$5000 every 3 months. 12 months in a year, so 4 times 3 months in a year.
Therefore the interest payed every year is $75 times 4. This is $300. $300/$5000 = $3/$50 = $6/$100. The numerator of the fraction is the desired percentage; 6%.

The U.S. Bureau of Labor Statistics reports that 11.3% of U.S. workers belong to unions (BLS website, January 2014). Suppose a s

vitfil [10]

Answer:

There is not enough evidence to support the claim that union membership increased.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 400

p = 11.3% = 0.113

Alpha, α = 0.05

Number of women belonging to union , x = 52

First, we design the null and the alternate hypothesis

$H_{0}: p = 0.113\\H_A: p > 0.113$

The null hypothesis sates that 11.3% of U.S. workers belong to union and the alternate hypothesis states that there is a increase in union membership.

Formula:

$\hat{p} = \dfrac{x}{n} = \dfrac{52}{400} = 0.13$

$z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

Putting the values, we get,

$z = \displaystyle\frac{0.13-0.113}{\sqrt{\frac{0.113(1-0.113)}{400}}} = 1.073$

now, we calculate the p-value from the table.

P-value = 0.141636

Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.

Thus, there is not enough evidence to support the claim that union membership increased.
