Hello,
There are 4 + 2 + 1 + 3 = 10 marbles in the bag.
The probability to get a red marble is 4/10 = 2/5 ; the probability to get a blue marble is 2/10 = 1/5 ; the probability to obtain a purple marble is 1/10 and the probability of getting a green marble is 3/10.
Have a nice day !
Answer:
Graph of solutions of:
y = x^2 -4 (red)
x + y + 2 = 0 (purple)
Step-by-step explanation:
10 times 0.84 is 8.4 or 8.40 is completely fine as well.
If the problem is
(17 ^ 3) * (79 ^ 7)
The steps are:
Step 1:
(17 ^ 3) = 4913
Step 2:
(79 ^ 7) = 1.92039E + 13
Step 3:
(4913) * (1.92039E + 13) = 9.43488E + 16
If the problem is
(173) * (797)
Step 1:
Multiply both terms with a calculator:
(173) * (797) = 137881
Answer:
51.9
8.9
78.5
8.8
Explanation:
You round up if the number to the right is 5 or greater.
So, apply this to the numbers and the 8 in A rounds up, going to a 51.9.
The 9 does not round up because of the one.
The 5 also does not round up because of the 2.
The 7 does round up because of the 6.
