If you look up “Four 4s Challenge” on yt you should find a couple videos explaining it! i just watched a little bit of one so i’ll try and help now though.

I’ll do 1-5 for you and try my best to explain :)) and if you need more answers or more help just let me know

So first, we need to find out how to get 1 using four 4s

1. (4/4)/(4/4)

this would read “four divided by four divided by four divided by four” which equals 1

2. 4/4+4/4

3. (4+4+4)/4

4. 4*(4-4)+4

5. (4*4+4)/4

Remember that you’ve gotta use an equation with just four 4s to get to every number

2x+4y+2z= -8<br> 5y-2z= 0<br> 4z= -20
kondaur [170]

Answer:

The given solution for the system is x = 5, y = -2 and z = -5

Step-by-step explanation:

Here, the given set of equations are:

2 x + 4 y +2 z = -8

5 y- 2 z = 0

4 z = -20

Now, simplifying each question one by one ,we get:

Simplifying third equation for the value of z:

4 z = -20 ⇒ z  = -20 / 4 = - 5

or, z =  -5

Simplifying second equation for the value of y:

Substitute the value of z  = -5 in (2) , we get

5 y- 2 z = 0    ⇒ 5 y - 2(-5)  = 0

or, 5 y + 10 = 0

or, 5 y = -10

or, y  =  -10/5 = -2

⇒ y = -2

Simplifying first equation for the value of x:

Substitute the value of z  = -5 and y  = -2 in (1) , we get

2 x + 4 y + 2 z = -8  ⇒ 2 x + 4 (-2) + 2 (-5) = -8

or,  2 x - 8 - 10 = -8

or, 2 x = 10

x = 10 / 2  = 5, or x  = 5

Hence, the given solution for the system is x = 5, y = -2 and z = -5

Event v occurs 28% of the time on Tuesdays.
vampirchik [111]

Answer:

68%

Step-by-step explanation:

Probability of occurrence of Event v = P(v) = 28% = 0.28

Probability of occurrence of both Events v and Event w together = P(v and w) = 19% = 0.19

We have to find what is the probability  that event w occurs with event v given that event v  occurs on a Tuesday. This is a conditional probability. In other words we have to find what is the probability of event w given that event v occurs of Tuesday. i.e we have to find P(w|v)

The formula to calculate this conditional probability is:

P(w|v) = \frac{P(v \cap w)}{P(v)}

Using the given values, we get:

P(w|v) = \frac{0.19}{0.28}\\\\ P(w|v) = 0.68\\\\ P(w|v) = 68\%

Therefore, the probability that even w will occur with event v given that event v occurs on Tuesday is 68%

Mariana bought 7 bags of candy. There were 61 pieces of candy in each bag. How many pieces of candy did Mariana buy?
Anna11 [10]

Answer:

427 pieces of candy

Step-by-step explanation:

Because there are 61 pieces of candy in EACH bag you'd have to multiply. So, 7 x 61 is 427, that means there are 427 pieces of candy in total.

If you need me to explain it again let me know, but I hope this helps!
