Suppose the measure of an angle is 67 degrees what is the measure of its complementary angle

avanturin [10]

Complementary angles are angles whose sum is 90 degrees.

90 - 67 = 23

23 degrees is the measure of its complementary angle.

Write the equation of the line, in standard form that has an x intercept at (3,0) and y

Nataly [62]

x intercept=a=3
y intercept=b=-2

We need the normal form first

$\\ \rm\bull\rightarrowtail \dfrac{x}{a}+\dfrac{y}{b}=1$

$\\ \rm\bull\rightarrowtail \dfrac{x}{3}-\dfrac{y}{2}=1$

Multiply by 6to bring standard form

$\\ \rm\bull\rightarrowtail 2x-3y=1$

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.
