Consider independently rolling two fair dice, one red and the other green. Let A be the event that the red die shows 3 dots, B b
max2010maxim [7]

Answer:

A & B are independent events. A & C, B & C are not independent events.

Step-by-step explanation:

Independent Events are the events, whose occurrences are completely unrelated to each other.

Event A 'Red dice getting 3' & Event B 'Green die getting 4' ; are unrelated to each other. The numbers on red dice & on green dice are not dependent on each other.

Event C 'Red & Green dice numbers showing sum = 7' is dependent on the numbers coming on red & green dice , i.e events A & events B respectively. So, event C is dependent on both events A & B.

The sum of twice a number d and 13 is 12
Mariana [72]
2d + 13 = 12

d = -0.5

-0.5 × 2 = -1

13 + (-1) = 12

Hope this helped☺☺

Explanations:

Twice a number d and 13 = 2d + 13 

The sum = Total 

Is 12 = "= 12"

That equals :

2d + 13 = 12

The weight of a honeybee is 1.2 x 10^-1 g. The weight of the pollen collected by the bee on one trip is 6.0⋅10 ^−2 g.
expeople1 [14]

Answer:

<em>The combined weight of the bee and the pollen will be  1.8\times 10^-^1 g.</em>

Step-by-step explanation:

The weight of the honeybee is  1.2\times 10^-^1 g and the weight of the pollen collected by the bee is  6.0\times 10^-^2 g.

For finding the combined weight, we just <u>need to add those two numbers</u>.

First we will convert each scientific notation as decimal numbers. So........

1.2\times 10^-^1 = 1.2\times \frac{1}{10}=0.12\\ \\ \\ 6.0\times 10^-^2 = 6.0\times \frac{1}{100}= 0.06

Now.......

(1.2\times 10^-^1)+(6.0\times 10^-^2)\\ \\ =0.12+0.06\\ \\ =0.18 = 1.8\times 10^-^1

Thus, the combined weight of the bee and the pollen will be  1.8\times 10^-^1 g.

The total surface area of this cuboid is 112cm squared find the value of x
soldier1979 [14.2K]

Answer:

x=2\sqrt{\frac{14}{3}}\ units  or  x=\frac{2}{3}\sqrt{42}\ units

Step-by-step explanation:

we know that

The surface area of a cube is equal to

SA=6x^{2}

where

x is the length side of a cube

In this problem we have

SA=112\ cm^{2}

substitute in the formula and solve for x

112=6x^{2}

x^{2}=112/6

square root both sides

x=\sqrt{\frac{112}{6}}\ units=2\sqrt{\frac{14}{3}}\ units=\frac{2}{3}\sqrt{42}\ units
