2.435 times or if it’s to the nearest whole number then it can go into it twice. 200+200= 400. It can’t go in 3 times because that would be 600.
Hey there! :)
Answer:
Choice A.
Step-by-step explanation:
Begin by calculating the probability of side effects for adults and children.
P(side effects) = # of those with side effects / total.
Therefore:
P(side effects | child) = 20/50 = 0.40.
P(side effects | adult) = 6/50 = 0.12.
The answer choice that correctly shows the probabilities of adults and children having side effects is choice A. The values are equivalent, and the statement is valid: Children have a much greater chance of having side effects than adults because 0.40 > 0.12.
Answer:
Step-by-step explanation:
2/5+ (7 1/5) = 3 +(-7) + 2/5 +(- 1/5)=
38/5 = -19/5
WE know that, product of two negative terms is positive and the product of a negative and a positive term is negative.
All the other options other than A violate this rule.
Hence, the answer is
A. -1 * -1 = 1
Answer: x = 4
y = - 3
Step-by-step explanation:
The given system of simultaneous equations is expressed as
x-3y = 13 ------------------------1
2x+4y=-4--------------------------2
We would apply the method of substitution in solving the equations. From equation 1, we would make x to stand alone by adding 3y to the left hand side and the right hand side of the equation. It becomes
x - 3y + 3y = 13 + 3y
x = 13 + 3y
Substituting x = 13 + 3y into equation 2, it becomes
2(13 + 3y) + 4y = - 4
26 + 6y + 4y = - 4
26 + 10y = - 4
Subtracting 26 from the left hand side and the right hand side of the equation, it becomes
26 - 26 + 10y = - 4 - 26
10y = - 30
Dividing the left hand side and the right hand side of the equation by 10, it becomes
10y/10 = - 30/10
y = - 3
Substituting y = - 3 into x = 13 + 3y, it becomes
x = 13 + 3 × - 3
x = 13 - 9
x = 4
