There are 250 students in a senior. of the 250 students, 102 are boys. there are 20 senior girls and 18 senior boys on the track team. What is the probablity a randomly chosen student from the senior class is a girl who does not run track?

Answers

Answer 1

Answer: If 102 are boys then 250 - 102 = 148 are girls.
If 20 girls run track, then 148 - 20 = 128 girls do not run track
probability a randomly chosen student from the senior class is a girl who does not run track = (probability the student chosen is a girl) * (probability the student does not run track)
= (148/250) * (128/250) = 128/250 = 62/125

The ratio of boys to girls in history class is 4 to 5. How many girls are in the class if there are 12 boys in the class?

Answers

$4x-\ amount\ of\ boys\n5x-\ amount\ of\ girls\n\n4x=12\ \ \ | fivide\ by\ 4\nx=3\n\n5x=5*3=15\n\nThere \ are\ 15 \ girls \ in\ class.$

Final answer:

In a class where the ratio of boys to girls is 4 to 5, if there are 12 boys, there would be 15 girls.

Explanation:

The subject of this question is mathematics, specifically the topic of ratios and proportions. To answer your question, the ratio of boys to girls is 4 to 5, this means that for every 4 boys in the class, there are 5 girls. If there are 12 boys, you simply multiply each side of the ratio by the same factor to keep the ratio the same. Since 12 divided by 4 equals 3, we also have to multiply 5 by 3. Hence, there are 15 girls in the class.

no power function is a function of the form : where and are constant real numbers and is a variable. The domain of a power function can sometimes be all real numbers, but generally a non-negativity is used to avoid problems with simplifying. The domain of definition is determined by each individual case.

Answer:

The answer is actually 9. Because i got 18.89 wrong.

Step-by-step explanation:

For the function f(x) = 3(x − 1)2 + 2, identify the vertex, domain, and range.The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2.
The vertex is (1, 2), the domain is all real numbers, and the range is y ≤ 2.
The vertex is (–1, 2), the domain is all real numbers, and the range is y ≥ 2.
The vertex is (–1, 2), the domain is all real numbers, and the range is y ≤ 2.
