Answer:
Well, 2 quarters are 2 coins. But, if you are asking the value of 2 quarters, then your answer will be, 50.
Step-by-step explanation:
So, <u>1 quarter = 25 cents</u>. So that means that, 25 x 2 or 25 + 25 = 50. So, your answer will be 50. Hope that helps! :)
I don’t think you can calculate the arc without the radius. All I know is that the angle is 110 degree
Answer:
D)1/3 ?
Step-by-step explanation:
Maybe 1/3
Do some research, I guess it's D).
I hope that helps (:
1. The entire fraction is negative if the numerator or denominator are negative.
if both parts of the fraction were negative, the entire fraction would be positive (- / - = +)
2. Of course, although most teachers ask you to put the negative sign in the fraction as a whole (before the fraction line) or in the numerator. never leave a fraction with two signs. in this case, if it has two signs and they are different, the whole fraction is NEGATIVE
3) No. the whole fraction is POSITIVE only if both the numerator and the denominator have the same sign, + + or - -
Answer:
The formula of circumference in a circle is 3.14 times diameter.
Step-by-step explanation:
3.14×20=62.8
The circumference is 62.8
Probability is the study of calculating the chances or likelihood of an event occurring out of the total number of events. This likelihood is always presented as part of a whole. It could be in fractions or percentages.
There are two techniques to apply to this problem. First, we use the repeated trial equation:
P = n!/r!(n-r)! * p^(n-r) * q^r
This is used to determine the probability that an event will occur exactly 'r' times out of 'n' trials. p is the probability of success, while q is the probability of failure. Together, they add up to 1. In this case, each kind of plant has 1/3 probability. So, p=1/3 and q=2/3.
Second thing to note when dealing with probability problems are 'hint words'. When you are asked to find the probability of event A 'AND' event B happening, then you multiply their probabilities. However, when you are asked to find the probability of event A 'OR' event B happening, then you add their probabilities. Hence, the solution to this problem is:
P = 6!/4!(6-4)! * (1/3)^6-4 * (2/3)^4 + 6!/5!(6-5)! * (1/3)^6-5 * (2/3)^5
P = 0.596 or 59.6%
