Answer:
1: Lowest-77 Higest: 99 Center: 88 Spread: 22
Step-by-step explanation:
Yes the ordered pair is a solution because you put in the values from the solution into the equation so: 6= -4+10, which is true. and 2(-4) + 6 = -2
Answer:
The correct answer is 54.76 years.
Step-by-step explanation:
The national health care expenditure (H) , in billion of dollars is modeled by
H = 29.57 × .
To measure the time before which national health expenditure reach 6000 billion dollars.
Thus putting the value of H = 6000 in the above modeled equation we get,
⇒ 6000 = 29.57 ×
⇒ =
⇒ 202.908 =
Taking logarithm with the base of e (㏑) both sides we get,
⇒ ㏑ 202.908 = ㏑
⇒ ㏑ 202.908 = 0.0970 × t
⇒ 0.0970 × t = 5.312
⇒ t =
⇒ t = 54.76.
Thus the total time required before which national health expenditure reach 6000 billion dollars is 54.76 years.
