Answer: x=15/19 =0.789
Step-by-step explanation: -12*x+1-(7*x-14)=0
-19x+15 = 0
Subtract 15 from both sides of the equation :
-19x = -15
Multiply both sides of the equation by (-1) : 19x = 15
Divide both sides of the equation by 19:
x = 15/19 = 0.789
x = 15/19 = 0.789
Answer:

Step-by-step explanation:
Answer:
(85.62, 90.38).
Step-by-step explanation:
The missing data can be assumed to be we have the following information:
¯x =88, s=10, n=70
Substituting the values in the following formula, we compute the 95% C.I for true population mean diastolic pressure as shown below:
95% C.I.=¯x±t(0.95,n−1)⋅Sm=¯x±t(0.95,70−1)⋅s√n=88±1.99⋅10√70=(85.62,90.38)
The answer is (85.62, 90.38).
