5 0

Answer: 0

Step-by-step explanation:

Given that :

Mean score on test = 5

Standard deviation on test = 2

Distribution = normal

The mean value when Converted to a z - distribution :

Zscore = (x - mean) / standard deviation.

Hence z score for the mean score will be :

X = mean score

Zscore = ( 5 - 5) / 2

Zscore = 0 / 2

Zscore = 0

Mean value when Converted to a z distribution will be 0

1) Find the ending balance after these transactions: Transactions: A. Your
dem82 [27]

The ending balance after the transactions is; $59.25

<h3>How to determine ending balance</h3>

To determine the ending balance after a number of transactions;

  • Let money inflow and balance be represented as positive.
  • Let money outflow be represented as negative.

Therefore; Since starting balance is; $822.67; we have;

  • <em>$822.67 + $227.45 - $600.00 + $50 - $100 - $200 - $3.50 - $2.50 - $134.87.</em>

The ending balance on the account is therefore; $59.25

Caleb and Mike both score the same amount of points in a game. Caleb has fifteen less than the total number of options. Mike has
ELEN [110]

Answer:

108points

Step-by-step explanation:

Let Caleb score be x and that of Mike be y. If Caleb and Mike both score the same amount of points in a game, then x = y.

The total number of option = x+y

Now, If Caleb has fifteen less than the total number of options, then;

x =(x+y)-15

x -(x+y)+15 = 0

x-x-y = -15

-y = -15

y = 15

Also if Mike has twice the total number of points decreased 201, then;

y = 2(x+y)-201

Since y = 15

15 = 2(x+15)-201

15 = 2x+30-201

15 = 2x-171

2x = 15+171

2x = 186

x = 186/2

x = 93

The total number of points they have altogether is x+y

x+y = 15+93

x+y = 108

Hence the total points that they have altogether is 108points
