OA is B -The figure shows a normal distribution with mean m and standard deviation d, including approximate percents of the distribution in each of the six regions shown. For a population of 800,000 subway riders, the numbers of subway trips taken per rider last January are approximately normally distributed with a mean of 56 trips and a standard deviation of 13 trips. Approximately how many of the riders took between 30 and 43 trips last January?

Explanation:
The inequality equation is basically the mg of per glass of milk times the m cups of milk + mg per glass of juice times the j glasses of juice should be greater than or equal to required 1,000 mg per day
Given that z = 3x² and x = y + 5
Substitute x = y + 5 into z = 3x²
z =3(y + 5)²
Answer: z =3(y + 5)²
Answer:
x = 70°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an external angle of the triangle, thus
x + 50 = 120 ( subtract 50 from both sides )
x = 70
