Answer:
Step-by-step explanation:
We have the expression:
The first thing we want to do, is to have the same denominator in both equations, then we need to multiply the first term by (2/2), so the denominator becomes 4*x
We will get:
Now we can directly add the terms to get:
We can't simplify this anymore
1) Add x to -2x, which is -x
2) Subtract 3 to 5, which is 2
Answer) A
Add the ratio together: 2 + 5 = 7
Divide this by the total number of plants;
70/7 = 10
Now times the ration by this number:
2:5 becomes 20:50 (times by 10)
This tells us we have 20 tulips as 50 daisies
Answer:
0.5, 80%
Step-by-step explanation:
Answer:
0.69
Step-by-step explanation:
A: obese
B: diabetes
P(A) = 61
P(B) = 31
P(A and B) = 23
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 61 + 31 - 23 = 69%=0.69
