For males in a certain town, the systolic blood pressure is normally distributed with a mean of 130 and a standard deviation of 9. Using the empirical rule, determine the interval of systolic blood pressures that represent the middle 68% of males.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
