Tim rolls a number cube labeled 1 through 6 and flips a coin. Which is the
ElenaW [278]

There are 3 numbers on the cube greater than 3 ( 4, 5, & 6)

This means he has a 3/6 = 1/2 chance of doing that.

He has a 1/2 chance of getting tails on the coin.

The probability of doing both would be the probability of the cube roll x the probability of the coin toss:

1/2 x 1/2= 1/4

The answer is 1/4

Find the total surface area of this cuboid.<br> 5 cm<br> 4 cm<br> 6 cm
mixer [17]

Answer:

The surface area of given cuboid is: 148 square centimeters

Step-by-step explanation:

Let

l = 5

w = 4

h = 6

The cuboid has 6 rectangular surfaces.

The surface area of a cuboid with height h, length l and width w is given by:

TSA = 2 ( lw+wh+hl )

Putting the values

TSA = 2(5*4 + 4*6 + 6*5)\\= 2(20+24+30)\\=2(74)\\=148\ cm^2

Hence,

The surface area of given cuboid is: 148 square centimeters

The recipe makes 20 portions of potato soup. Richard follows the recipe but wants to make 4 portions. Complete the amounts of ea
-Dominant- [34]

Answer:

Oil: 24 ml; Onion: 56 g; Potatoes: 0.36 kg; Milk: 0.44 l

Step-by-step explanation:

First, we see how much of the soup recipe he wants make.

4 portions out of 20 portions = 4/20 = 1/5 = 0.2

He wants to make 0.2 of the amount of the recipe.

Now we multiply every amount by 0.2

Oil: 0.2 * 120 ml = 24 ml

Onion: 0.2 * 280 g = 56 g

Potatoes: 0.2 * 1.8 kg = 0.36 kg

Milk: 0.2 * 2.2 l = 0.44 l

Using the Binomial Probability table, find P(X) when n = 7, X &lt; 3, and p = 0.5 A. 0.273 B. 0.500 C. 0.227 D. 0.773
Nat2105 [25]

Answer:

0.227

Step-by-step explanation:

Given that X is binomial with n=7 and p =0.5

To find the probability for P(X<3)

i.e. we have to find prob as =P(x=0,1,2)

=P(X=0)+P(X=1)+P(x=2)

P(X=r)=7Cr(0.5)^7

Using binomial table we find prob

P(X<3)=0.2265

Round off this to 3 decimals as

0.227

Hence answer is 0.227
