1. 4c + 6a < = 120
4c + 4a < = 100
if u sub in 20 for c and 6 for a, u will find that the answer is : No,because the bike order does not meet the restrictions of 4c + 6a < = 120 and 4c + 4a < = 100.
==========================
2. 2x + y < 10
2x - 4y > 8
answers are : E,F,G
==========================
3. y < = -2x + 3
y < = x + 3
==========================
4. y > = -3x + 1
y < = 1 / 2x + 3
answer : Both lines are solid. 1 lines passes thru (-2,2) and (0,3), shaded below the line. Other line passes thru (0,1) and (1,-2) and is shaded above the line....I am not 100% sure on this one
==========================
5.y < -3x + 3
y < x + 2
answer is (1,-5)
==========================
6. y < = 2x - 2
y > -x + 3
Answer:
a) We conclude that the menager use the hypergeometric distribution.
b) We conclude that the menager use the binomial distribution.
Step-by-step explanation:
a) We know that in probability theory, the hypergeometric distribution is a discrete probability distribution that describes the probability of k successes in n draws, without replacement.
We conclude that the menager use the hypergeometric distribution.
b) We know that the binomial distribution describes the probability of k successes in n draws with replacement.
We conclude that the menager use the binomial distribution.
-5x - 7 < 28.....add 7 to both sides
-5x < 35....divide both sides by -5, change the inequality sign (u change the inequality sign when dividing/multiplying by a negative number)
x > -7
Answer:
55
Step-by-step explanation:
The three angles form a straight line, so they add to 180.
x + x + 70 = 180
Combine like terms
2x+70 =180
Subtract 70 from each side
2x+70-70 =180-70
2x= 110
Divide by 2
x = 55
SQT = x
So SQT = 55
