Answer:
I believe the answer is 20
The class starts out with 26 students, of whom 12 are girls and, perhaps unlike Mr Morris, are sure of it.
The probability of the first random choice being a girl is 12/26. If successful, there are now 25 students left, of whom 11 are girls. The probability of a girl on the 2nd random choice is 11/25. The probability that BOTH random choices are successful is (12/26) x (11/25). That's (132/650), or about 20.31% (rounded).
Answer:
5(x-3)+7=-45
Step-by-step explanation:
The only possibly way for 5 to multiply 2 numbers is if those numbers are in parenthesis
Answer:
(168,12)
Step-by-step explanation:
Substitute x = 10y+48 in the first equation.
We have got the y-value. Our next goal is to find the x-value by <u>substituting</u><u> </u><u>y-value</u><u> </u><u>in</u><u> </u><u>any</u><u> </u><u>given</u><u> </u><u>equations</u><u>.</u><u />
For me, I will be substituting y = 12 in the first equation.
<u>Answer</u><u> </u><u>Check</u>
Substitute both x-value and y-value in both equations.
Our first equation is true for both values.
Our second equation is true for both values.
Thus, the answer is (168, 12)
Answer: For altitudes up to 36,000 feet, the relationship between temperature and altitude can be described by the formula t=-0.0035a+g, where t is the temperature in degrees Fahrenheit, a is the altitude in feet, and g is the ground temperature in degrees Fahrenheit. Solve this formula for a.
