Answer:
34,860
Step-by-step explanation:
In a sample of 32 residence, 24 take Vitamin C. From here we can get the proportion of residents who take Vitamin C, which is 24/32 = 3/4 = 0.75
0.75 in percentage is 75%. This means 75% of the residents in sample take Vitamin C.
We can expect the same percentage of people in entire population to take Vitamin C.
Total population of city = 46480
Expected number of residents who take vitamin C in the city = 75% of 46480
= 0.75 x 46480
= 34860
This means, 34860 is an estimate of number of city residents who take Vitamin C supplement daily.
Answer:
x° = 83°
Step-by-step explanation:
All angles in a triangle (any kind of triangle: right, isosceles, equilateral etc.) add up to 180 degrees.
So, if we are given the ABC triangle, then:
angle A + angle B + angle C = 180°
In this particular case, we are given values of two angles, so using the previous relation, we can write:
x° + 44° + 53° = 180°
Now, it's easy to find x°:
x° = 180° - 44° - 53°
x° = 83°
Answer:
3m² - 6
Step-by-step explanation:
Summing the 2 expressions
2m² + 3m - 4 + m² - 3m - 2 ← collect like terms
= (2m² + m²) + (3m - 3m) + (- 4 - 2)
= 3m² + 0 + (- 6) = 3m² - 6
