274 faculty surveyed regarding their plans for the weekend 126 plan to grade papers 132 plan to attend game 130 plan to do chores 29 plan to grade papers and attend game 67 plan to grade papers and chores 49 plan to atten game and chores 9 plan to grade papers, attend game, and chores. how many planned to do at most one of these activities?

people who opted for atmost one activity are 24.

Step-by-step explanation:

you can easily find the answer by using the set formula.

AUBUC=A+B+C+AUB+BUC+CUA-A∩B∩C

answer on calculating by this formula comes out to be 24 who opted for performing only single task among all the three tasks mentioned.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
