Answer:
6/25
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
probability that a 7th grader is chosen = total number of 7th graders / total number of students
total number of 7th graders = 180
total number of students = 200 + 220 + 180 + 150 = 750
180 / 750
To transform to the simplest form. divide both the numerator and the denominator by 30
6 / 25
Are you rounding to the nearest 100’s place?
Answer: vertex (-1, 0) axis of symmetry -> x = -1
Step-by-step explanation:
f(x) =
to find the vertex do
x+1 = 0
to find the x value
x = -1
plug -1 into the equation
f(-1) =
f(-1) = 3(0)
f(-1) = 0
Therefore, the vertex is (-1, 0)
The axis of symmetry is
x = -1
because that is where the lowest x value is
Answer:
5 days
Step-by-step explanation:
Put the given number in the formula and solve for x.
2065500 = 8500·3^x
243 = 3^x . . . . . . . . . . . divide by 8500
log(243) = x·log(3) . . . take logarithms
log(243)/log(3) = x = 5 . . . . divide by the coefficient of x
After 5 days, the number of bacteria in culture will be 2,065,500.
1/27 is the greater answer
