Let's find out.
David needs to score an average of 145 across all four games, so first we do:
145 × 4 = 580
Then we add all the scores he currently has:
139 + 143 + 144 = 426
Then we subtract 426 from 580 to find out how much he needs to score for his fourth:
580 - 426 = 154
David needs to score 154 on his 4th game to have an average score of 145 for all 4 games.

Answer:
45
Step-by-step explanation:
Only numbers ending in 5 or 0 are divisible by 5. If the units digit is 0, there can be no tens digit that is 1 less. So, the units digit must be 5 and the tens digit must be 4.
The number is 45.
Color in the model for each fruit. The number of squares colored is the percentage. If you put the number of squares colored over 100, you have the fraction. Then put the decimal point in front of the number.
Examples-
28 acres of apples-
28%
28/100 (This can be simplified)
0.28
5 acres of peaches

Answer:
(a) -1.0133
(b) 2.32
(c) -2
(d) 0.9867
(e) 2.9867
Step-by-step explanation:
The <em>z</em>-score of a raw score <em>X</em> is a standardized score that follows a normal distribution with mean 0 and standard deviation 1.
The formula to compute the <em>z</em>-score is:
<u>Given</u>:
Mean (<em>μ</em>) = $775
Standard deviation (<em>σ</em>) = $75
(a)
For <em>X</em> = $699 the <em>z</em>-score is:
(b)
For <em>X</em> = $949 the <em>z</em>-score is:
(c)
For <em>X</em> = $625 the <em>z</em>-score is:
(d)
For <em>X</em> = $849 the <em>z</em>-score is:
(e)
For <em>X</em> = $999 the <em>z</em>-score is:
