Answer:
.33 as a decimal or 33%
Step-by-step explanation:
Divide 1/3 and get .33 as your decimal. To convert to a percentage multiply your decimal by 100. (<em>.33 x 100 = 33 </em>)
Answer:
Step-by-step explanation:
For this case we have a sample size of n = 250 units and in this sample they found that 24 units failed one or more of the tests.
We are interested in the proportion of units that fail to meet the company's specifications, and we can estimate this with:
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".
The confidence interval for a proportion is given by this formula
For the 98% confidence interval the value of 
and 
, with that value we can find the quantile required for the interval in the normal standard distribution.
And the margin of error would be:
Obtuse angle
Which is a angle between 90 and 180 degrees. Add all of them up you’ll get 105 which is in between 90 and 180.
If the right triangle has legs with lengths 42 m and 34 m and the hypotenuse with length 54 m, then you need:
1. P=42+34+54=130m (perimeter) of <span>new curbing to go around the space between three streets;
</span>
<span>2.
sq. m. (area) of </span><span>sod to cover the space.
</span>
All given choices are right.
