Answer: a.
Step-by-step explanation:
So let’s say a=1 and b=1 so then 1*1=2 (So 2=c) so in conclusion c/b (or 2/1) equals a (1) which would be the a (1). You can plug in any number into the equation (a*b=c) and (c/b=a) and it will always get the same answer. As long as you use the same numbers for a, b, and c. I really hope this helps.
Look at it !
--> 3.2 is more than 1.
--> 10 is more than 1.
--> If you multiply them, the product is SURELY more than 1.
√2 is irrational because let's suppose √2 is a rational number. Then, we write
√2=a/b where a and b are whole number, b≠0
From the equality √2=a/b, it follows that 2= a²/b²( Make all of them to the second power), or a²=2×b²
Then, a is 2 times some other whole number. In symbols, a=2k where k is this other number
If we substitute a=2k into the original equation 2=a²/b², this is what we get:
2=(2k)²/b²
2=4k²/b²
2b²=4k²
b²=2k². This means that b² is even, from which follows again that b itself is we . And that is contradiction, and thus our original assumption (that √2 is rational). Therefore, √2 can not be rational
√2=1.41421356237..
√2=1.4( rounded to the nearest tenth). Hope it help!
The theoretical probability is the probability you'd expect before performing the experiment. So, assuming the die is fair, every outcome has the same probability. Since there are 6 numbers on the die, every number appears, theoretically, with probability 1/6.
The experimental probability is the probability you estimate after performing the experiment. You divide the number of cases a certain outcome happened, and divide by the total number of trials.
In this case, you performed 50 rolls, and the die landed on six 12 times. This means that the experimental probability is 12/50, or 6/25.
Answer:
30:90
Step-by-step explanation:
120 divide by four
If you take one fourth out (30 or 1/4) it will remain three fourths (90 or 3/40
1 +3 = 4
120/4 = 30
.30x1 =30
30x3=90
