Answer:

the first one first the second second and the last last

Step-by-step explanation:

2 1/5 + 22/5 = 4 2/5

9 2/5 + (-5 3/5)= 4 1/5

-8 2/5+9 1/5=1/15

Answer:

2 1/5 + 2 2/5 > 9 2/5 + (-5 2/5) > -8 2/5 + 9 1/5

Step-by-step explanation:

We can calculate each of  

4 \frac{3}{5}\\3 \frac{4}{5}\\1 \frac{4}{5}

We can compare them now:

4 3/5 > 3 4/5 > 1 4/5

2 1/5 + 2 2/5 > 9 2/5 + (-5 2/5) > -8 2/5 + 9 1/5

Brums [2.3K]

2/3x = 6

Multiply both sides by 3x

2 = 6.3x

2 = 18x

x = 2/18

x = 1/9

in a final exam you have four multliple choice questions left to do. each questions has five suggested answers and only one of t
kompoz [17]

Answer:

The probability that you get zero questions correct is 0.4096

The probability that you get one questions correct is 0.4096

The probability that you get three questions correct is 0.0256

Step-by-step explanation:

These probability can be describe with a Binomial Distribution. These distribution can be used when we have n identical and independent situations in which there is a probability p or probability of success and a probability q or probability of fail. Additionally q is equal to 1 - p. The probability of x for a situation in which we can apply binomial distribution is:

P( x,n,p) = n Cx * p^{x } * q^ {n-x}

Where x is the variable that says the number of success in the n situations

And nCx is calculate as:

nC x = \frac{ n!}{ x! (n-x)! }

From the question we can identify that:

  • n is equal to 4 multiple choice question
  • p is 1/5 or 0.2, the probability of get one question correct
  • q is 4/5 or 0.8, the probability of get one question incorrect

Then the probability of get zero questions correct of 4 questions is:

P( 0, 4, 0.2) = 4 C0 * p^{0 } * q^ {4-0}= 0.4096

The probability of get one question correct of 4 questions is:

P( 1, 4, 0.2) = 4 C1 * p^{1 } * q^ {4-1}= 0.4096

The probability of get three questions correct of 4 questions is:

P( 3, 4, 0.2) = 4 C3 * p^{3 } * q^ {4-3}= 0.0256

Two birds sit at the top of two different trees. The distance between the first bed and a birdwatcher on the ground is 34 feet t
stira [4]

Answer:

Step-by-step explanation:

The given triangle is a right angle triangle.

The distance between the first bed and the bird watcher on the ground represents the opposite side of the right angle triangle.

The distance between the birdwatcher and the second bird is 47 feet. This represents the hypotenuse of the right angle triangle. To determine the angle of depression, x degrees, we would apply the Sine trigonometric ratio which is expressed as

Sin θ = opposite side/hypotenuse

Sin x = 34/47 = 0.723

x = Sin^-1(0.723)

x = 46.3 degrees to the nearest tenth.
