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.

I NEED HELP ASAP!! BRAINLIEST TO BEST ANSWER!!!!!!!!!!!!!! The moving van traveled 455 miles in eight hours and 45 minutes what

AveGali [126]

Answer:

52 miles per hour

Step-by-step explanation:

455 miles in 8 hr 45 min =

455 miles in 8.75 hours

$\frac{455 miles}{8.75 hours} = \frac{x}{1 hour}$

8.75(x) = 455(1)

$\frac{8.75(x)}{8.75} = \frac{455(1)}{8.75}$

x = 52

I NEED HELP ASAP! : An initial population of 175 quail increases at an annual rate of 22%. Write an exponential function to mode

goblinko [34]

Answer:

About 473 quails.

$P=175(1.22)^t$

Step-by-step explanation:

Exponential equation with $P_0$ as the initial amount and rate of r is:

$P=P_0(1+r)^t$

$P=175(1+.22)^t$

$P=175(1.22)^t$

After 5 years the population will be:

$P=175(1.22)^5$

$P \approx 472.9739$

So the population will be about 473 quails.
