Answer:

0.218

Step-by-step explanation:

If x represents student that study more than one day, then the probability of x will be 78.2%. In other words, out of 1000 student, 782 of them will study more than one day while 218 of them only study for one day or less

The question asking for the probability that a randomly selected student did not study more than one day, which negation of X statement. So the answer will be ~X= 100%- 78.2%= 21.8%= 0.218

Solve 5x -c = k for x

inysia [295]

x = $\frac{k+c}{5}$

isolate 5x by adding c to both sides of the equation

5x = k + c ( divide both sides by 5 )

x = $\frac{k+c}{5}$

If x€{-2,-1,0,1,2,3,4,5} find the solution set 7-x>0 ii 3-4x>-2 vi 3x+4>-2

maw [93]

Answer:

i) {-2 , -1 , 0 , 1 ,2 , 3 , 4 , 5}

ii) {-2 , -1 , 0 , 1}

iii) {-1 , 0 , 1 ,2 , 3 , 4 , 5}

Step-by-step explanation:

i) 7 - x > 0

⇔ 7 > x

⇔ x < 7

⇔ x ∈ {-2 , -1 , 0 , 1 ,2 , 3 , 4 , 5}

____________________________

ii) 3 - 4x > -2

⇔ 3 + 2 > 4x

⇔ x < 5/4

⇔ x ∈ {-2 , -1 , 0 , 1}

____________________________

iii) 3x + 4 > -2

⇔ 3x > -2 - 4

⇔ 3x > -6

⇔ x > -6/3

⇔ x > -2

⇔ x ∈ {-1 , 0 , 1 ,2 , 3 , 4 , 5}

aron lei is making identical balloon arrangements for a party. He has 32 maroon balloons and 24 white balloons, he wants each ar

alexandr402 [8]

Answer:

The greatest number of arrangements that he can make if every balloon is used is 8.

Step-by-step explanation:

The greatest number of arrangements will be the greatest common factor between 24 and 32.

GCF of 24 and 32:

We keep factoring both numbers by prime factors, while they can both be divided by the same number. So

24 - 32|2

12 - 16|2

6 - 8|2

3 - 4

There is no factor for which we can divide both 3 and 4. So the GCF is 2*2*2 = 8.

This means that the greatest number of arrangements that he can make if every balloon is used is 8.
