Answer:
Step-by-step explanation:
(a) A parameter of a population measures the characteristics of the population, In the question the proportion of all the persons who have health insurance and the mean of the entire dollar amount that Americans spent on health care in the past year measure the population.
Invariably, the proportion of persons having health insurance, and the mean dollars spent on health care for all Americans are the population parameter
(b) A statistics measure the characteristics of the sample.
In the question, the sample of 1500 Americans are considered to estimate the proportion of all Americans, proportion of all the persons who have health insurance among 1500 and the sample mean of all the dollar amounts that the selected Americans spent on healthy care in the past year describe the sample.
Invariably, the sample proportion of persons having health insurance, and the mean dollars spent on health care for 1500 selected Americans are sample statistics
Answer:
x=18
pq=101
qr=101
pr=202
Step-by-step explanation:
6x-7=5x+11
+5x pasa a restar como -5x al primer miembro y -7 pasa como +7x al segundo miembro y la ecuacion quedaria asi:
6x-5x=11+7
6x-5x=x
11+7=18
entonces x=18
pq=6x-7
pq=6(18)-7
pq=108-7
pq=101
y como se sabe que pq=qr porque hay un punto medio y dos segmentos cuando los divide un punto medio esos dos segmento miden igual entonces
por eso pq=qr
y como pq=101 qr=101
por ultimo
pr=pq+qr
pr=101+101
pr=202
Step-by-step explanation:
f(-1)=3×(-1)²-4×(-1)
=3×1-4×(-1)
=3+4
=7
