Answer:
0.9938
Step-by-step explanation:
Let mean blood pressure be = x
Pr ( x < 119 ) can be found using ' z value ' = ( x - u ) ÷ ( s / √n ) ; where x = 119 , u = mean = 117 , n = no. of sample items = 144 , s = standard deviation = 9.6
z = (119 - 117) ÷ (9.6 / 144) = -2 ÷ (9.6 / 12) = -2 / 0.8 → z = 2.5
Pr (x < 119) = P (z < 2.5)
P = 0.9938
Answer: x=5
5x-3 (x-3)= -6 +6x -5
5x -3x +9 =-6 +6 x -5
Answer:
x=14.5
If the answer is 14.5 move to J.
Explanation:
The sum of adjacent angles is 180
(8x-11)+(4x+17)=180
12x+6=180
12x=174
x=14.5
Answer:
the circumference is C = 34π units.
Step-by-step explanation:
The circumference of a circle of diameter d is C = πd.
Here the diameter is 34 units. Thus, the circumference is C = 34π units.
Answer:
Propability of getting either sum is 2/9
Step-by-step explanation:
Well, we know that there are 36 total arrangements of the two six sided die. So we have a possibility of 3,4 and 4,3. Likewise, we have a possibility of 5,2 and 2,5. We also have a possibility of 1,6 and 6,1. That takes care of the probability That you get two die that add up to 7. Now for 11, you have 5,6 and 6,5. So since you asked for the probability of getting either or, you add all the probabilities, which is 6/36+2/36=8/36=2/9. So the probability of getting either sum is 2/9.
