Answer:
The testing statistic is -2.237
Step-by-step explanation:
Test statistic (z) = (sample mean - population mean) ÷ (population standard deviation/√n)
sample mean = 6.3 ounces
population mean = 6.4 ounces
population standard deviation = 0.2 ounces
n (sample size) = 20
z = (6.3 - 6.4) ÷ (0.2/√20) = -0.1 ÷ 0.0447 = -2.237
Answer:
Mean: 58
Median: 58
Step-by-step explanation:
- The mean is a <u>type of </u><u>average</u>. <u>It is the </u><u>sum (total)</u><u> of all the values in a set of data</u>, such as numbers or measurements, divided by the number of values on the list. <u>To find the mean, add up all the values in the set. Then divide the sum by how many values there are.</u>
- <u>The median is the </u><u>middle </u><u>number</u>; <em>found by ordering all data points and picking out the one in the middle</em>
FINDING THE MEAN:
57 + 54 + 59 + 57 + 61 + 58 + 60 = 406
406 ÷ 7 = 58
FINDING THE MEAN:
Arrange the numbers from <u>smallest to greatest:</u>
54, 57, 57, 58, 59, 60, 61
Find the <u>median</u> number:
54, 57, 57, <em><u>58</u></em>, 59, 60, 61
The median is: <u><em>58</em></u>
Answer:
The common ratio is 
The next term in the sequence is 2
Step-by-step explanation:
In a geometric sequence, the common ratio is the constant value you multiply a term by in order to find the value of the following term. Therefore, it is mathematically calculated as the quotient between a term and the term immediately before it. And it is in fact That is:
common ratio 
This quotient should be true for any two consecutive terms in the sequence.
so using the first two terms, we find:

You can test that this common ratio is true for all other terms listed:

So now, in order to find the term that follows, all we need to do is to multiply the last term given (8) by this common ratio:

the medians to the sides of triangle ABC
