Answer: 78. 571 unit²

Step-by-step explanation:

To find the area of a circle, we simple use the formular;

area of a circle = Πr²

The value of π = 22/7

r= radius of the circle = 5

area of a circle = Πr²

= 22/7 × 5 ×5

=550 / 7

= 78. 57143

=78. 571 unit² to the nearest hundredth

Therefore area of the circle with radius 5cm is 78. 571 unit²

The systolic blood pressure of adults in the USA is nearly normally distributed with a mean of 122 and standard deviation of 22

marin [14]

Answer: 4.27% of adults in the USA have stage 2 high blood pressure.

Step-by-step explanation:

Let x be a random variable that denotes a person with high blood pressure .

Given: Average blood pressure: $\mu=122$

Standard deviation: $\sigma=22$

Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher.

The probability that an adult in the USA have stage 2 high blood pressure:

$P(x\geq160)=P(\dfrac{x-\mu}{\sigma}}\geq\dfrac{160-122}{22})\\\\=P(z\geq1.72)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z$

Hence, 4.27% of adults in the USA have stage 2 high blood pressure.
