Mathematics
1 answer:
krek1111 [17]3 years ago
7 0

Answer:

1 and 1/8

Step-by-step explanation:

The number 1.125 can be writen using the fraction 1125/1000 which is equal to 9/8 when reduced to lowest terms.

It is also equal to 1 1/8 when writen as a mixed number.

You can use the following approximate value(s) for this number:

1.125 =~ 1 (if you admit a error of -11.111111%)

Answer:

35

Step-by-step explanation:

Maneesha: 75 % × 37 sunflower seeds equals to 27.75

27.75 is a decimal so rounded off they become 28

her friend: 1/3 × 21 = 7 pumpkin seeds

the total of the seeds will be 28 + 7 = 35 seeds

Margin of error: 0.009; confidence level: 99%; p and a unknown
mafiozo [28]

Answer:

n=\frac{0.5(1-0.5)}{(\frac{0.009}{2.58})^2}=20544.44  

And rounded up we have that n=20545

Step-by-step explanation:

Assuming this question: Use the data to find minium sample size required to estimate population proportion. Margin of error: 0.009, confidence level: 99%, p and q are unknown.

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

Solution to the problem

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 99% of confidence, our significance level would be given by \alpha=1-0.99=0.01 and \alpha/2 =0.005. And the critical value would be given by:

z_{\alpha/2}=-2.58, z_{1-\alpha/2}=2.58

The margin of error for the proportion interval is given by this formula:  

ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}    (a)  

And on this case we have that ME =\pm 0.009 and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}   (b)  

Assuming an estimation of p as \hat p =0.5. And replacing into equation (b) the values from part a we got:

n=\frac{0.5(1-0.5)}{(\frac{0.009}{2.58})^2}=20544.44  

And rounded up we have that n=20545

The Frostburg-Truth bus travels on a straight road from Frostburg Mall to Sojourner Truth Park. The mall is 5 miles west and 3 m
Mamont248 [21]

Answer:

D. 11.4 miles.

Step-by-step explanation:

Distance between the Center and the Mall = √(5^2 + 3^2) = √34.

Distance between The Park and the Center = √(4^2 + 4^2) = √32.

So the Distance between The Mall and the Park is √34 + √32

=  11.4 miles (answer).
