Question 15 Partially correct answer. Your answer is partially correct. Try again. The probability density function of the time it takes a hematology cell counter to complete a test on a blood sample is f left-parenthesis x right-parenthesis equals 0.04 for 52 < x < 77 seconds. Round your answers to 2 decimal places. (a) What proportion of tests require more than 70 seconds to complete

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

step-by-step explanation:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
