Answer:

$- 1.2(3x - 3) = 4(3x + 0.9) \\ - 3.6x + 3.6 = 12x + 3.6 \\ 12x + 3.6x = 3.6 - 3.6 \\ 15.6x = 0 \\ \\ x = \frac{0}{15.6} \\ \\ x = 0$

I hope I helped you^_^

A six-sided Fair number cubis rolled 100 times as part of an experiment. The frequency of the role of the number 3 is 20. W hich

Anastasy [175]

Answer:

The Theoretical probability is 1/6.

The experimental probability is 1/5

Step-by-step explanation:

Given

Rolls: 100

Outcome of 3 : 20

Required

Which of the options is true (See attachment for options)

From the attachment, we understand that the question requires that we calculate the experimental and theoretical probability.

The experimental probability (E) is calculated as thus:

$E = \frac{Outcomes}{Total\ Rolls}$

$E = \frac{20}{100}$

$E = \frac{1}{5}$

The theoretical probability (T) is calculated as thus:

A cube has 6 faces, one of which is the face 3.

So, T is:

$T = \frac{n(face\ 3)}{n(Total)}$

$T = \frac{1}{6}$

Hence, C is true

Step-by-step explanation:

1st- 4

2nd- 4+15-10= 9

3rd- 9+15-10=14

4th- 14+15-10=19

5th- 19+15-10=24

6th- 24+15-10=29

7th- 29+15-10=34

8th- 34+15-10=39

9th- 39+15-10=44

10th- 44+15-10=49

11th- 49+15-10=54

12th-54+15-10=59

Help please inequalities are kicking my butt any help is greatly appreciated thank you in advance

Hitman42 [59]

Answer:

Correct option is (C)

Step-by-step explanation:

we are given that -Tim design a pair of shorts,S, and T-shirts,t.

Tim sell Sorts for $12 and T-shirts for $8 each.

Tim can work atmost 18 hours a day so we can write $time\leq 18$

Time taken to design a T-shirt is 30 minutes and for Shorts, it is 45 minutes.

$\frac{30}{60}t+\frac{45}{60}s\leq 18\\\text{Multiply both the sides by 60}\\30t+45s\leq 1080\\\text{Divide both the sides by 45}\\s+0.66t\leq 24\\\text{Subtract 0.66t from both the sides}\\s\leq 24-0.66t$

He must design 12 itesm each day, so we can write $t+s\geq 12$

Further it can be written as

$t+s\geq 12\\\text{Subtract t from both the sides}\\s\geq 12-t$

Also Tim can not design more than 30 items in one day, so we can write

$t+s\leq 30\\\text{Subtsract t from both the sides}\\s\leq 30-t$

Hence from the above equations , its claer that

$s\geq 12-t,s\leq 30-t,s\leq 24-0.66t,s\geq 0,t\geq 0$
