Answer:
Measures of all angles are 57°, 57°, 123°, 123°
Step-by-step explanation:
Given:
Sum of two angles = 114°
Find:
Measures of all angles
Computation:
Sum of all 4 angles = 360°
Sum of remain 2 angles = 360° - 114°
Sum of remain 2 angles = 246°
So, first two angles = 114° / 2 = 57°
Second two angles = 246° / 2 = 123°
So, measures of all angles are 57°, 57°, 123°, 123°
I think that it would be -62
To find the mean, add up all of the miles and divide by the number of years. 12100 + 15758 + 12200 + 11800 + 12750 = 64608. 64608/5 = 12921.9. The mean (the average) is 12,921.9 miles.
To find the median, put the numbers in order and find the middle number. The middle number is 12200. The median (middle number) is 12,200 miles
To find the mode, you would look for the number that is repeated the most. In this data set, no number repeats, so there is no mode. There is no mode for this data set.
The mean (average) would be the best measure of central tendency to predict how many miles Gina will drive in the sixth year.
I hope this helps! Can I have Brainliest, please? :)
Answer:
= 4 grams
Step-by-step explanation:
The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass.
Therefore, using the formula;
N = O × (1/2)^n ; where N is the new mass, O is the original mass, and n is the number of half lives.
In this case;
N = 130 × (1/2)^5
= 130 × 1/32
= 4.0625
≈ 4 g
