Answer:

31:21

Step-by-step explanation:

3/5 = 0.6. multiply both number by 0.6 to get 24 and 7.2 now you cannot have part of a win or a loss that makes no sense. so round it and you get 24 and 7 add those together to get 31. subtract 31 from 52 to get 21. he had 31 wins and 21 losses.

Answer:

Standard Form: 47.9

Scientific Notation Form: 4.79 x 10

Step-by-step explanation:

1.2 x 106 = 127.2

1.7 x 103 = 175.1

175.1 - 127.2 = 47.9

47.9 = 4.79 x 10

I need to solve these two equations using either substitution or elimination
vitfil [10]

Answer:

y = -15

x = -10

Step-by-step explanation:

1/4x - 1/2 = 5 (1)

3x + 2/3y = -40 (2)

Multiply (1) by 4

1/4x - 1/2 = 5

1/4x * 4 - 1/2y * 4 = 5 * 4

4/4x - 4/2y = 20

x - 2y = 20 (3)

Multiply (2) by 3

3x + 2/3y = -40 (2)

3x * 3 + 2/3y * 3 = -40 * 3

9x + 6/3y = -120

9x + 2y = -120 (4)

x - 2y = 20 (3)

9x + 2y = -120 (4)

Using elimination method, Add (3) and (4)

9x + x = -120 + 20

10x = -100

x = -100/10

x = -10

Substitute x = -10 into (3)

x - 2y = 20 (3)

-10 - 2y = 20

-2y = 20 + 10

-2y = 30

y = 30/-2

y = -15

y = -15

x = -10

A quiz consists of 40 multiple choice​ questions, each with five possible​ answers, only one of which is correct. If a student g
Artist 52 [7]

Answer:

8 and 2.529

Step-by-step explanation:

The computation of the mean and the standard deviation is shown below:

Given that

Total number of questions is n =  40

The Probability of correct answer is p =  \frac{1}{5}

So, the probability of the wrong answer is q =  1 - \frac {1}{5} = \frac{4}{5}

Moreover, this is the binomial distribution

Based on the above information

The mean is

= n \times p

= 40\times \frac{1}{5}

= 8

Now the variance is

= 40\times \frac{1}{5} \times \frac{4}{5}

= \frac{32}{5}

So, the standard deviation is

= \sqrt{\frac{32}{5} }

= 2.529

hence, the mean and the standard deviation is 8 and 2.529 respectively
