Option B → The sample space has 12 different outcomes → This is the correct option because we take the 2 sides of a coin and multiply it by the 6 sides on a number cube which would give us 12 different outcomes in the sample space.

Answer:

Option B, The sample space has 12 different outcomes

Step-by-step explanation:

Step 1: Determine which of the following is true

Option A → Heads and an even number are very likely outcomes → This is false, although both of these can occur they don't occur "very likely"

Option B → The sample space has 12 different outcomes → This is the correct option because we take the 2 sides of a coin and multiply it by the 6 sides on a number cube which would give us 12 different outcomes in the sample space.

Option C → The sample space has 8 different outcomes → This is false because it doesn't follow the rules of finding the sample space.

Option D → Each result is equally likely → This is false because a coin flipped can land on heads or tails which is 50% while a number cube is usually between 1-6 meaning that there is a 16.667% chance of landing on a number.

Answer: Option B, The sample space has 12 different outcomes

PLEASE HELP!

We have that
If (5x-4+13x=5) --------------> then x=1/2
Step 1
let's substitute the value of x = (1/2) in the expression [5x-4+13x] and verify its result
5*(1/2)-4+13*(1/2)
(5/2)-4+(13/2)
(5-4*2+13)/2----------> (5-8+13)/2=10/2=5
then
5=5-----------> the value of x = (1/2) satisfies equality

What is the variance of the following data? If necessary, round your answer to two decimal places. 17, 13, 13, 22, 11, 20

Bond [772]

Variance is the standard deviation squared but we're not going to use that now. Let's first calculate the mean:

mean = (17+13+13+22+11+20)/6 = 16.

Now for each value, let's see how far it is from this mean. We'll square these distances and average them. That's our variance.

17 distance 1 squared = 1
13 distance 3 squared = 9
13 distance 3 squared = 9
22 distance 6 squared = 36
11 distance 5 squared = 25
20 distance 4 squared = 16

Now average these outcomes:

variance = (1+9+9+36+25+16)/6 = 16.

So the variance by coincidence is the same as the mean.

Answer C is your answer.

the boundary of a rectangular farm field in ireland has a straight rock wall along one side and fences along its other three sid

Inessa [10]

Answer:

781250 $ft^{2}$

Step-by-step explanation:

Let y is the length of the farm field

Let x is the width of the farm field

Given that, no fencing is necessary along the rock wall, so we can find the perimeter of the farm is:

2x + y = 2500 feet

<=> y = 2500 -2x

The are of the farm has the following formula:

A = x*y

<=> A = x(2500 - 2x)

<=> A = 2500x -2 $x^{2}$

To have the maximum area of field in square feet, we need to use differentials to estimate:

$\frac{dA}{dx}$ = 2500 - 4x

Set $\frac{dA}{dx}$ = 0, we have:

2500 - 4x = 0

<=> x = 625 feet.

=> y = 2500 - 2*625 = 1250 feet

So the maximum area of field is:

A = x*y = 625*1250 = 781250 $ft^{2}$

if you have four rolls of quarters three rolls of Dimes and six rolls of nickels how much do you have

xz_007 [3.2K]

We know that
the number of coins that each roll contains is
rolls of quarters-------> 40 coins
rolls of Dimes---------> 50 coins
rolls of nickels------> 40 coins

four rolls of quarters------> 4*40*$0.25-----> $40
three rolls of Dimes-----> 3*50*$0.10------> $15
six rolls of nickels-------> 6*40*$0.05-----> $12

total=[40+15+12]------> $67

the answer is
$67
