Answer:
To work this problem out you would do it as if it were just a simple equation
7x-19<16 (you would first have to add 19 to both sides)
7x<35 (then you would divide by 7 to get the variable by itself)
x<5 ( you answer would then be 5)
Step-by-step explanation:
Probability of getting a subject that is not diabetic, given that the result is negative is 90.3%
Answer:
probability of blue ball is 1/2
probability of yellow ball is 1/4
Step-by-step explanation:
We have given 6 blue balls 3 green balls and 3 yellow balls
Total number of balls are: 12

we have to find the probability of choosing a blue ball:

Then the ball was placed in the bag since, it is given replacement
Now, we have to find probability of choosing a yellow ball

Let me set an example to help solve this, say the poster is 100 inches by 90 inches. the length of the poster is reduced by 12% so subtract 12 from 100 to get you new length of 78 inches. the width is increased by 15% so multiply 90 by 15% to get 13.5 inches and add the to the 90 inches you have to get your new width of 103.5 inches. multiply them together to get your new area then divide the new area by the old area, subtract that number by 1 and multiply it by -1.
8.5+(4×1)+(4×-2.5k)=-24.5
8.5+(4)+(-10k)=-24.5
(8.5+4)+(-10k)=-24.5
12.5+(-10k)=-24.5
-10k=-24.5-12.5
-10k=-37
k=-37/-10
k=37/10
