Answer:

x = 10

x = -10

Step-by-step explanation:

x = 10

We can start by comparing the tens digit, as each number has two digits.

29 vs 10

2 vs 1

2 is greater than 1; therefore, as the biggest digit is larger and each number has the same amount of digits, 29 > 10 and x= 10 < 29

x = -10

29 is positive, and -10 is negative. Any negative number is smaller than any positive number, so x = -10 < 29

Which of the following scores has the better relative position ( as measured by the z score) a. A score of 53 on a test for whic

Kisachek [45]

Answer:

d. Cannot be determined with the information provided.

Step-by-step explanation:

Z-score:

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

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 p-value, we get the probability that the value of the measure is greater than X.

Finding the better relative position:

The score with the better relative position is the one with a higher z-score.

To find the z-score, the mean and the standard deviation is needed, and in this question, the standard deviation is not given, and thus, the correct answer is given by option d.

What is the radius of the circle who’s equation is x^2 + y^2 = 9

Svetllana [295]

Answer:

r=3

Step-by-step explanation:

The equation of a circumference is $(x-a)^2+(y-b)^2=r^2$ .
Then , in this case $r^2=9$ , and then to know the value of r we just simply have to calculate the square root of 9, which is 3.

A pizza chain records how long it takes customers to receive their delivery orders. Suppose the distribution of these delivery t

SCORPION-xisa [38]

Answer:

The probability that the mean delivery time from the sample of 25 orders xˉ is farther than 2 minutes from the population mean cannot be calculated.

Step-by-step explanation:

As given in the question statement, the distribution of delivery times is strongly skewed to the right. The population distribution is skewed to right. Too much skewed distribution can cause the statistical model to work ineffectively and affects its performance. The probability can also not be calculated because the sample size is too small. Small sample size affects the results and makes them less reliable because it results in a higher variability and likelihood of skewing the results.
