Answer:
False, it is nowhere near Rio de Janeiro
Step-by-step explanation:
All internal angles in a quadrilateral add to 360
so
x+110+110+70=360
x+290=360
minus 290 both sides
x=70 degrees
Answer: 18
Step-by-step explanation:
The options are:
A. 23
B. 18
C. 14
D. 32
Since we are told that the ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16. This simply means that the ratio of flour tortillas to the total number of packages on the shelf was (16 -7 = 9) 9 to 16.
Therefore, to get the number that could represent the number of packages of flour tortillas the clerk put on the shelf we have to find the multiple of 9 in the question given . This will be:
Multiples of 9 = 9, 18, 27, 36, 45 ....
Based on the option, the answer will be 18.
Answer:
The first student, with 20 measurements, will have the more precise interval due to the larger sample size.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval has the following format:
In which z is related to the confidence level, s to the standard deviation and n to the sample size.
The margin of error is inversely proportional to the square root of the sample size, which means that a larger sample will lead to a lower margin of error, that is, to a more precise interval.
In this question:
One student will use 5 measurements, other 20. The first student, with 20 measurements, will have the more precise interval due to the larger sample size.
Answer:
3. (x-6)
Step-by-step explanation:
x^2-5x-6
--
Find factors of -6 that could be added that equals to -5
Factors=
-6 and 1
x^2-5x-6 factored is (x-6)(x+1)
so the answer would be (3) (x-6)
