Step 1- use your index and middle finger to find your pulse in your wrist .
step 2- count the number of pulse in 1 minute.
step 3- subtract your resting heart rate from your max heart rate .
step 4- multiply the number from step 3- by 0.6.
D). would be the answer to your question
Answer:
a. The expected number of adults who smoke is 70
b. The probability that fewer than 20 smoke is 5.7%
c. The probability that from 45 to 80 smoke is the 12,8% to 22,8%
d. The probability that 70 or more smoke is the 20%
Explanation:
a. 350 is the 100% so you have to do a equation
350 -100%
X - 20% = 20% x 350/100 = 70 adults
b. 350 -100%
20 - X = 20% x 100%/350= 5.7% probability
c. 350 - 100%
45 - X = 45 x 100%/350= 12.8% probability
350 - 100%
80 - X = 80 x 100%/350= 22.8% probability
d. 350 - 100%
70 - X = 70 x 100%/350= 20% probability

You can use <u>conchoidal </u>fractures to tell the direction from which a projectile struck glass.
Conchoidal fracture, frequently seen in quartz and glass, is referred to as a fracture with smooth, curving surfaces that resemble the interior of a seashell. Rapidly applying stress to fragile things causes the fracture surface to grow with a smooth curved surface. Such materials frequently exhibit conchoidal fracture because they lack a crystalline structure or cleavage. Glass develops ridges along the edge when a bullet strikes it; these fractures are apparent in profile. These fractures are almost parallel to the direction of applied force (the direction which the projectile came from).
