Hypertension is defined as a blood pressure reading over 140 mm Hg systolic and/or 90 mm Hg diastolic. Hypertension, if not corrected, can cause long term health problems. In the college-age
population (18-24 years), about 9.2% have hypertension. Suppose that a blood donor program is
taking place in a college dormitory this week (final exams week). Before each student gives blood,
the nurse takes a blood pressure reading. Of 196 donors, it is found that 29 have hypertension. Do
these data indicate that the population proportion of students with hypertension during final exams
week is higher than 9.2%? Use a 5% level of significance.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

5/12, or 5: 12

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
