Answer:
Chris: -1.1315.
Karen: -1.6038.
Step-by-step explanation:
The z-score = (x - m) / d where m = the mean, d = the standard deviation and x is the individual score.
Chris: z-score = (185.13 - 185.52) / 0.327
= -1.1315.
Karen: z-score = (110.13 - 110.3) / 0.106
= -1.6038.
Step-by-step explanation:

Answer:
Jack can form four rectangular prisms with 20 unit cubes.
Step-by-step explanation:
Number of unit cubes Jack has = 20
Factors of 20 = 1, 2, 4, 5, 10, 20
The possible dimensions of a rectangular prism that can be formed by these unit cubes may be,
1 × 1 × 20 (One cube at the base)
1 × 2 × 10 (2 cubes at the base)
1 × 4 × 5 (4 cubes at base in a single row)
2 × 2 × 5 (4 cubes at the base with 2 cubes in length and 2 cubes in width)
Therefore, Jack can form four rectangular prisms with 20 unit cubes.
Step-by-step explanation:
I think its 63 times because 50X60 will get you 3,000 and you already have 320 so 3,000+320 is 3,320 and when you add 50, 3 more times you get 3,470 so it would be 63 times
