Answer:
1.(B) $31.80
Step-by-step explanation:
First you need to add all the prices of the things Jonathan bought.
$8.75+$7.45= $16.20
Then you can subtract it from the original Total that they brought to the movies.
$16.20-$48.00= $31.80
Jonathan has $31.80 left
Answer:
The correct option is (a) 0.9780.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:
As the sample selected is quite large, i.e. <em>n</em> = 110 > 30, the central limit theorem can be applied to approximate the sampling distribution of sample proportion by a Normal distribution.
The mean and standard deviation are:
Compute the probability that the sample proportion of students living in the dormitories falls in between 0.60 and 0.80 as follows:
*Use a <em>z</em>-table.
Thus, the probability that the sample proportion of students living in the dormitories falls in between 0.60 and 0.80 is approximately equal to 0.9780.
The correct option is (a).
Answer:
It has no solution since it is a simultaneously equation. And when you solve to find x and y it gives 0
Answer: 3.16, 8, 9, 12
Step-by-step explanation:
= 3.16
2^3 = 2 * 2 * 2 = 8
|-9| = 9
1.2 x 10^1 = 1.2 * 10 = 12
3.16, 8, 9, 12
Just switch the x and the 3
