Answer:
x>1 the bottom graph
Step-by-step explanation:
(18x - 9 > 9) and (2x - 4 > -10)
Do the first inequality first
18x - 9 >9
Add 9 to each side
18x - 9+9 > 9+9
18x> 18
Divide each side by 18
18x/18 > 18/18
x >1
Then the second inequality
(2x - 4 > -10)
Add 4 to each side
2x-4+4>-10+4
2x>-6
Divide each side by 2
2x/2 >-6/2
x>-3
Since this is an and
x>1 and x>-3
We take the more restrictive
x>1
Answer:
Step-by-step explanation:
x²+x²=14²
2x²=196
x²=196/2=98
x=7√2 ft
10t - 4t + 3t = 8
13t - 4t = 8 (will do addition first)
9t = 8
So, Tanisha’s equation will be equivalent
As Tanisha’s equation is :
9t = 8
Answer:
4(x-5)=4x-20
4x-20=4x-20
+<u>20 +20</u>
4x=4x
<u>-4x </u>-4x therefore there's infinite solutions
0=0
The odds ratio for birds having long beaks being able to fly against birds not having long beaks being able to fly is 3.76.
<h3>What is an odds ratio?</h3>
An odds ratio is a measure of the strength of an association with the exposure and outcome.
The odds ratio can be calculated by dividing the odds of the first group (exposure) by the odds of the second group (outcome).
Flies Does not fly Total
Long beak 11 7 19
Not a long beak 3 13 15
Total 14 20 34
Probability of long beaks flying = 0.79 (1/14)
Probability of not having long beaks flying = 0.21 (3/14)
Odds ratio = 3.76 (0.79/0.21)
Thus, the odds ratio for birds having long beaks being able to fly against birds not having long beaks being able to fly is 3.76, showing greater odds of association.
