Answer:
- The variation in the sample means makes it possible to make predictions about the population mean.
- The actual population mean is greater than 236.
- The actual population mean is less than 245.
Step-by-step explanation:
<u>Sample data</u>
- 1 2 3 4 5 6
- 240 236 245 243 238 242
<u>Mean = sum of sample data/sample frequency</u>
- (240+236+245+243+238+242)/6 = 240.67
Answer choices:
The variation in the sample means makes it possible to make predictions about the population mean.
The actual population mean is greater than 236.
The actual population mean is less than 245.
The actual population mean is greater than 245
The population mean is the average of the sample means.
Solution:
Formula of perimeter = 
So, 2W + 2H = 32.4 ... (1)
Ratio = 5:4
So, 
4W - 5H = 0 ... (2)
Solve equation (1) and (2).
W = 9.0 and H = 7.2
Use the Pythagorean theorem,
D = 11.52
D = 11.5
Hence, the measure of diagonal is 11.5 inches.
Examine the given terms of the sequence. Is every term the same multiple of the previous term? If so, that multiplier is called the "common ratio," r
If "a" is the first term of the sequence, then a_n = (a)(r)^(n-1).
Answer:
63
Step-by-step explanation:
Answer:
total = $41
Step-by-step explanation:
If Julio spent $41 and now has no money that means that after spending that money he was left with $0. Having both of these numbers we can make a very simple algebraic equation to find out his total before the purchase.
total - $41 = $0
Now we simply add $41 to both sides which will give us the actual amount of the total.
total - $41 = $0
+$41 +$40
-----------------------------
total = $41
Now we can see that Julio had a grand total of $41 before making his purchases.
