6 > 1/2 x
21 - 6 = 15
15 divided by 2 = 7.5
7.5
Answer: 30 in.
Step-by-step explanation:
If it's an equilateral triangle, all sides are the same length. Therefore
3x + 15 = 7x - 5
x = 5
After figuring out x = 5, replace the x with five and solve the equation.
3(5) + 15 = 30
7(5) - 5 = 30
Now that we know the length of two sides, we can state that the third side-length <u>also</u> equals 30 inches because it is an equilateral triangle, meaning all sides are congruent/ the same.
Answer: 0.7619
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size :
We assume that the variable is normally distributed.
The value of z-score is given by :-
a) For x= 46.9 years
The p-value :
Hence, the probability that the average age of those doctors is less than 46.9 years =0.7619
Answer: radius=3
X = -2
Y = 5
Step-by-step explanation:
Answer: Lee would make $25 on commission.
Step-by-step explanation: I found this by multiplying 500 by .05 or 5%. Lastly you can check this by taking 25 times 20, because 5% x 20 = 100%, so if 25 was really equal to 5% then it would equal the whole, or 500.
Hope this helps.
