Answer: 45% of 62 would be 27.9
Step-by-step explanation:
So the way I always figure these out is state the facts first. So we know 62 is equal to 100% in the equation. That means if we divided 62 by 10 then we would also divide 100% by 10%.
62 (divided by) 10 = 6.2
100% (divided by) 10% = 10%
Now we know what 10% percent of 62 is. We need to find 45%. Well divide 6.2 by 2 to get 5 % of 62. (That would be 3.1). Now that we know 10% of 62 and 5% of 62 we are all set.
6.2 x 4 = 24.8
24.8 = 40%
3.1 + 24.8 = 27.9
27.9 = 45% of 62
Answer:
The value of x for given expression is .
Step-by-step explanation:
Given expression as :
×(x - 2) + 3 = ×(3 x - 4)
Or, - + 3 = -
Or, - 1 + 3 = -
Or, + 2 = -
<u>Now, rearranging both sides</u>
So, 2 + = -
<u>Taking LCM , we get</u>
=
Or, =
Or, 5 x = × 8
Or, 5 x =
Or, 5 x = 28
∴ x =
So, The value of x =
Hence,The value of x for given expression is . Answer
Answer: because the 7 in 0.77 is in the tens place, while 0.077 has a 0 in the tens place, and 7 is greater than 0.
Answer:
a. independent event P(AuB)=P(A)+P(B)
b. mutually exclusive event P(AuB) = P(A) + P(B) - P(AnB)
c. independent event P(A and B) = P(A).P(B)
d. complement P(A') = 1 - P(A)
Step-by-step explanation:
a. For two events A and B the union of the two sets is simply all the elements present in both set. This can be expressed as
P(AuB)=P(A)+P(B)
b. Two events are said to be mutually exclusive if they cannot occur at the same time. i.e no same element must be present in both events at a time. This can be expressed as
P(AuB) = P(A) + P(B) - P(AnB)
c. event A and event B are said to be independent if the incidence of event A does not affect the probability of the event B.
This can be expressed as
P(A and B) = P(A).P(B)
d. complement of an event are simply all the occurrence not in he set but in the universal set.
the complement of set A can be expressed as
P(A') = 1 - P(A)
Answer:
(x+6)(x-2)
Step-by-step explanation:
you need to find 2 numbers with a sum of 4 and a product of -12, which is 6 and -2, then you factor it out.
