The answer is 60. Because if u do 30% x by 200 but u need to get rid of the percent which means u divide it by 100 to get rid of a percent and multiply by a hundred to get a percentage. So it would be 30 x 200 divided by 100.
Answer:
Is a less than or greater than b?
Is c less than or greater than b?
Step-by-step explanation:
Since we already know that both a and b are less than 0, they will be to the left of the 0 marker on the numberline. All you need to know is which is greater or smaller.
The same goes for c and d. Both are greater than 0 so they will be to the right of the 0 marker on the numberline. All you need to know is which is greater or smaller.
The effect of this increase <u>will reduce the variability of the estimate</u>.
<u>Step-by-step explanation</u>:
Variability of a sample can be determined with the help of variance and standard deviation. Sampling variability shows the variation in the estimate between the samples.
Variability is defined as the how close the scores in the distribution are to the middle of the distribution.
In the above scenario, the polling company increases the size of the random sample of voters before election. The proportion of the voters is estimated with the help of poll. The effect of increasing the sample is to reduce the variability of the estimate.
