A potential side effect of using oral contraceptives is an increase in blood pressure. Given below are the systolic blood pressures of 10 women measured before beginning and after having taken oral contraceptives for a 6-month period and from women not taking contraceptives. Assuming the blood pressures to be normally distributed, do these data suggest that using an oral contraceptive increases significantly the systolic blood pressure? Woman 1: Before= 113 After=118
Woman 2: Before= 117 After=123
Woman 3: Before= 111 After= 114
Woman 4: Before= 107 After= 115
Woman 5: Before= 115 After= 122
Woman 6: Before= 134 After=140
Woman 7: Before= 121 After=120
Woman 8: Before= 108 After=105
Woman 9: Before= 106 After=111
Woman 10: Before=125 After=129

i think it would be 42cm

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
