Answer:
Option B
Step-by-step explanation:
Given:
total No. of students liking peas= 78
total no. of male students= 100
total number of students= 200
no. of male students liking peas= 42
Now we need to find are liking peas and being male independent or dependent events
P(likes peas)= 78/00
=0.39
=39%
P(likes peas/male) = 42/100
= 42%
as the two probabilities are not equal the two events are dependent.
Hence option B is correct: Dependent;
since these probabilities are not equal, the events are dependent!
Answer: 7x+6 = 6x-3
Step-by-step explanation: Lets begin by applying the distributive property and then combining like terms to see what the result of these steps will look like.
2(x+3)+5x = 3(2x-1)
Apply the distributive property: 2 x X = 2x and 2 x 3 = 6 and 3 x 2x = 6x and 3 x -1 = -3
2x+6+5x = 6x-3
Combine Like Terms: 2x + 5x = 7x
7x+6 = 6x-3
Answer:
x^2 – 4 = 0
Step-by-step explanation:
When x = - 2,
x^2 - 4 = 0
( - 2 )^2 - 4 = 0
4 - 4 = 0
When x = 2,
x^2 - 4 = 0
2^2 - 4 = 0
4 - 4 = 0
Answer:
d. 7 × (10 + 9) = (7 × 10) + (7 × 9)
Step-by-step explanation:
The format of writing numbers in distributive property is a(b+c) = (a×b)+(a×c)
We can see that in choice d. 7 × (10 + 9) = (7 × 10) + (7 × 9) it is in correct format of writing numbers in distributive property. Thus, choice d. is correct.
Verification:-
a(b+c) = (a×b)+(a×c)
7 × (10 + 9) = (7 × 10) + (7 × 9)
