Answer:

(Choice B) B 22:222:222, colon, 2

(Choice C) C 55:555:555, colon, 5

(Choice D) D 99:999:999, colon, 99

Step-by-step explanation:

Three ratios that are equivalent to 11:111:111

(Choice A) A 1:111:111, colon, 11

Dividing through by 1

= 1 : 111 : 111

(Choice B) B 22:222:222, colon, 2

Dividing through by 2

= 11 : 111 : 111

(Choice C) C 55:555:555, colon, 5

Dividing through by 5

= 11 : 111 : 111

(Choice D) D 99:999:999, colon, 99

Dividing through by 9

= 11 : 111 : 111

(Choice E) E 110:10110:10

Dividing through by 10

11 : 1011 : 1

The equivalent ratios are:

(Choice B) B 22:222:222, colon, 2

(Choice C) C 55:555:555, colon, 5

(Choice D) D 99:999:999, colon, 99

The difference in the x- coordinates of two points is 3, and the difference in the y- coordinates of the two points is 6. What i
USPshnik [31]

Answer:

2

Step-by-step explanation:

Slope or gradient of a line is given by dividing change in y axis by the change in x axis. Slope is represented by m hence m=\frac {\triangle y}{\triangle x} where \triangle y is the change in y axis while \triangle x is the change in x co-ordinates. Substituting \triangle y with 6 units while 3 units substitute \triangle x then the slope will be m=\frac {6}{3}=2

Therefore, the gradient is 2

A jar contains 4 white and 4 black marbles. We randomly choose 4 marbles. If 2 of them are white and 2 are black, we stop. If no
Airida [17]

Answer:

<em>Find the probability of success in a single trial and then think about the nature of the problem (when do we stop).  </em>

Step-by-step explanation:

Observe that in the single trial, we have (8 4) possibilities of choosing our set of balls. If we have chosen two white balls and two black balls, the probability of doing that is simply  

p=(4 2)*(4 2)/(8 4)

This is well know Hyper geometric distribution. Now, define random variable X that marks the number of trials that have been needed to obtain the right combination (two white and two black balls). From the nature of the problem, observe that X has Geometric distribution with parameter p that has been calculated above. Hence  

P(X = n) = (1— p)^n-1 *( p )

<em>Find the probability of success in a single trial and then think about the nature of the problem (when do we stop).  </em>

Eric took $7000 of his income last year and invested it, part at 7% and the rest at 9%. He earned $570 from investments. How muc
mihalych1998 [28]

Answer:

He invested 3,000 at 7% and 4,000 at 9%.

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=7,000 (1)

0.07x+0.09y=570 (2)

You can solve for x in (1)

x=7,000-y (3)

Now, you can replace (3) in (1) and solve for "y":

0.07(7,000-y)+0.09y=570

490-0.07y+0.09y=570

0.02y=80

y=80/0.02

y=4,000

Finally, you can replace the value of "y" in (3):

x=7,000-4,000

x=3,000

According to this, the answer is that he invested 3,000 at 7% and 4,000 at 9%.
