Arccos is the same thing as inverse cosine which is used when you are looking for an angle measure. Make sure your calculator is in degree mode. Hit 2nd button then cos and you will see this on your screen:
and it is following the parenthesis there that you will enter your decimal. The inverse cosine of .67 is an angle measure of 47.93°

Answer:
25%
Step-by-step explanation:
First we calculate the probability of rolling a number greater than 3, that is, it can be 4, 5 or 6.
The probability of each number is 1/6, so:
P1 = (1/6) + (1/6) + (1/6) = 3/6 = 1/2
Then, we calculate the probability of rolling a prime number, that is, 2, 3 or 5.
As we have again 3 numbers, the probability P2 will also be 1/2
Then, the final probability is the product of both P1 and P2:
P = P1 * P2 = (1/2) * (1/2) = 1/4 = 25%
Answer:
true
Step-by-step explanation:
16,000 / 10 = 1,600
Answer:
The number is 205 kg
Step-by-step explanation:
Let
x ----> the number
we know that
8.4%=8.4/100=0.084
The linear equation that represent this problem is equal to
0.084x=17.22
Solve for x
Divide by 0.084 both sides
x=17.22/0.084
x=205 kg
