Select the two values of x that are roots of this equation.
2x-5=-3x². X=1 x=-5/3
Answer:
0.0172 = 1.72% probability that he or she has at least one food allergy and a history of severe reaction
Step-by-step explanation:
We are given these following probabilities:
4% probability of that a child younger than 18 in the United States has at least one food allergy.
If a child has at least one food allergy, 43% probability of having a history of severe reaction.
If a child younger than 18 is randomly selected, what is the probability that he or she has at least one food allergy and a history of severe reaction
The multiplication of the probabilities. So
0.04*0.43 = 0.0172
0.0172 = 1.72% probability that he or she has at least one food allergy and a history of severe reaction
Answer:
x = 5/6-4y^2
Step-by-step explanation:
^ = to the power of and * = times
y = square root of 6x-5/4x
(times by the square root on either side, sorry I don't know how to word it)
y^2=6x-5/4x
(times by 4x either side)
4xy^2= 6x-5
(+5 either side)
4xy^2+5=6x
(-4xy^2 either side)
5=6x-4xy^2
(factorize)
5=x(6-4y^2)
(divide by (6-4y^2))
5/6-4y^2 = x or x = 5/6-4y^2
Tell me if this is incorrect.
Answer:
x = 20
Step-by-step explanation:
m<ABC and m<CBA are complementary angles which means their sum is 90 degrees:
2x + 3x - 10 = 90 add like terms
5x - 10 = 90 add 10 to both sides
5x = 100 divide both sides by 5
x = 20 to find the angles replace x with 20
m<ABC = 40 and
m<CBA = 50
