Here are some basic rules for rounding:
1)  Locate the digit that is in the place value that you want to round to
2)  Look at the digit immediately to the right of the digit you want to round
*if that digit is a 0, 1, 2, 3, or 4, the digit you're rounding stays the same as it     is and everything after it turns into a 0 (or if it's in the decimals, the other digits drop off
*if that digit is a 5, 6, 7, 8, or 9, the digit you're wanting to round goes up to the next digit, and everything behind it turns into a 0 (decimals drop off)

Hope this helps

garri49 [273]

Complete question:

The manager of a supermarket would like to determine the amount of time that customers wait in a check-out line. He randomly selects 45 customers and records the amount of time from the moment they stand in the back of a line until the moment the cashier scans their first item. He calculates the mean and standard deviation of this sample to be barx = 4.2 minutes and s = 2.0 minutes. If appropriate, find a 90% confidence interval for the true mean time (in minutes) that customers at this supermarket wait in a check-out line

Answer:

(3.699, 4.701)

Step-by-step explanation:

Given:

Sample size, n = 45

Sample mean, x' = 4.2

Standard deviation \sigma = 2.0

Required:

Find a 90% CI for true mean time

First find standard error using the formula:

S.E = \frac{\sigma}{\sqrt{n}}

= \frac{2}{\sqrt{45}}

= \frac{2}{6.7082}

SE = 0.298

Standard error = 0.298

Degrees of freedom, df = n - 1 = 45 - 1 = 44

To find t at 90% CI,df = 44:

Level of Significance α= 100% - 90% = 10% = 0.10

t_\alpha_/_2_, _d_f = t_0_._0_5_, _d_f_=_4_4 = 1.6802

Find margin of error using the formula:

M.E = S.E * t

M.E = 0.298 * 1.6802

M.E = 0.500938 ≈ 0.5009

Margin of error = 0.5009

Thus, 90% CI = sample mean ± Margin of error

Lower limit = 4.2 - 0.5009 = 3.699

Upper limit = 4.2 + 0.5009 = 4.7009 ≈ 4.701

Confidence Interval = (3.699, 4.701)

What happens when the two addends have opposite signs and the number with the larger magnitude (size) is positive?
zimovet [89]

Answer:

The smaller addend is subtracted from the bigger addend

Step-by-step explanation:

Represent the two numbers with a and b such that a > b

So, the mathematical representation will be

+a + (-b)

Open the bracket

+a -b

<em>This implies that the smaller addend (b) is subtracted from the bigger addend (b)</em>

<em></em>

<em>Take for instance; a = 6 and b = 4</em>

<em>This gives</em>

<em></em>+6 + (-4)<em></em>

<em></em>

<em>Open the bracket</em>

<em></em>= +6 - 4<em></em>

<em></em>= 2<em></em>

Indicate below wether the equation in the box is true or false 6/12= 1/3
Hatshy [7]

Answer:

False

Step-by-step explanation:

6/12 simplifies into 1/2 (six is half of twelve) and 1/2 does not equal 1/3.

You can also plug this into a calculator and see that 6/12=0.5 and 1/3=0.333
