Yes
Step-by-step explanation:
19/3 is equal to 6.3333 repeating which is rational (repeating decimals are rational)
Answer:
99.96% probability that the sample proportion will be within 10 percent of the population proportion
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Proportion p = 0.75
Mean:

Standard deviation of the proportion:

What is the probability that the sample proportion will be within 10 percent of the population proportion?
This is the pvalue of Z when X = 0.75+0.1 = 0.85 subtracted by the pvalue of Z when X = 0.75 - 0.1 = 0.65. So
X = 0.85



has a pvalue of 0.9998
X = 0.65



has a pvalue of 0.0002
0.9998 - 0.0002 = 0.9996
99.96% probability that the sample proportion will be within 10 percent of the population proportion
Answer:
14
Step-by-step explanation:
2x + 11 + 4x - 5 = 90° because this is a right triangle.
6x + 6 = 90°
6x = 84
x = 14

Step-by-step explanation:
50+25=75
since he spent another half 75 is the other half
so 75+75
