In the spinner there are eight numbers numbered from 1 to 8.
To solve this problem, we must remember that probability is:
Probability = number of successful events / number of total
events
a. P (even number). There are 4 even numbers, therefore the
probability is:
P (even number) = 4 / 8
P (even number) = ½ = 0.5 = 50%
The probability of getting an even number is 50%.
b. P (a number greater than
3). There are 5 numbers greater than 3, therefore the probability is:
P (number greater than 3) = 5
/ 8
P (number greater than 3) = 0.625
= 62.50%
The probability of getting a number greater than 3 is 50%.
c. P (an odd number). Similar
to the even number, there are 4 odd numbers. Therefore,
The probability of getting an odd number is 50%.
Answer:
14 days
Step-by-step explanation:
The half life of a substance is the time required until the object has only half of the inicial mass.
So, to find the inicial mass of the object, we use t = 0 in the equation A(t):
A(0) = 600*e^0 = 600
Half of this mass is 300, so we can use A(t) = 300 and then find the time:
300 = 600e^-0.05t
e^-0.05t = 0.5
ln(e^-0.05t) = ln(0.5)
-0.05t = -0.6931
t = 13.862 days
Rounding to nearest day, we have that t = 14 days
Answer: 1. I will bring my umbrella.
2. You work 20 hours a week, and you make $175.00.
Step-by-step explanation:
We know that a conditional statement "If p then q", is an if-then statement in which p is a hypothesis and q is a conclusion.
Now, for the given conditional statement "If it rains, then I will bring my umbrella. "
Here, q=" I will bring my umbrella." Therefore, the conclusion is "I will bring my umbrella".
For the next conditional statement "If you work 20 hours a week, then you make $125.00."
The statement "You work 20 hours a week, and you make $175.00." is false, because $175 is false conclusion here for the same hypothesis.
The length of the shortest side of the hexagon is; 41.833 inches
<h3>How to find the perimeter of a Polygon?</h3>
Let the length of the shortest side of the hexagon be x. Now, a hexagon has six sides and if the next side is 10 inches longer than the previous side, then the length of the six sides are;
x, x + 10, x + 20, x + 30, x + 40, x + 50
Perimeter is given as 401 inches. Thus;
x + x + 10 + x + 20 + x + 30 + x + 40 + x + 50 = 401
6x + 150 = 401
6x = 401 - 150
6x = 251
x = 251/6
x = 41.833 inches
