While Jackie was in Hawaii, she would dive for shells. One afternoon she dove −7.8 feet. Her next two dives were each 2 1/8 feet deeper than the dive before it. What were the depths of her second and third dives?
Dive 2: ? ft
Dive 3: ? ft
Answers
Answer:
Dive 2: -9 37/40 feet
Dive 3: -12 1/20 feet
Step-by-step explanation:
To solve this, we subtract 2 1/8 from -7.8 twice. First, convert -7.8 to a mixed number, that gets us -7 8/10. Now, we find the LCM of 8 and 10. That is 40. Now, we multiply 1/8 by 5/5 to get 5/40. Now, we multiply 8/10 by 4/4 to get 32/40. Now, we subtract 2 5/40 from -7 32/40. This gets us -9 37/40. That means Dive 2 was -9 37/40 feet. Now, we subtract 2 5/40 from -9 37/40. That gets us -12 2/40. We can simplify that to -12 1/20. That means Dive 3 was -12 1/20 feet.

Three small squares are drawn inside a larger square as shown. What is the length of the line marked with a question mark?
Answers
Answer:
19
Step-by-step explanation:
let the smallest square be A, medium square is B and the largest is C ;
as the length side of the main square is 28, we can find that,
A= 28-22 = 6
C= 28-15 = 13
So to find B,
A+B+C = 28
B = 28-A-C
B = 28-6-13 = 9
So the line with questioned mark is,
28-9 = 19

The SAT is standardized to be normally distributed with a mean µ = 500 and a standard deviation σ = 100. What percentage of SAT scores falls:_____.
a. Between 500 and 600? the answer says 34.13% <<< how do you get to that???
b. Between 400 and 600?
Answers
Answer:
34.134%
68.268%
Step-by-step explanation:
Given that:
Mean (m) = 500
Standard deviation (s) = 100
Percentage between 500 and 600
P(500 < x < 600)
P(x < 600) - P(x < 500)
Z = (x - m) / s
P(x < 600)
Z = (600 - 500) /100 = 1
P(x < 500)
Z = (500 - 500) / 500 = 0
P(Z< 1) - P(Z < 0)
0.84134 - 0.5
= 0.34134
= 0.34134 * 100%
= 34.134%
B.) Between 400 and 600
P(x < 400)
Z = (400 - 500) /100 = - 1
P(x < 600)
Z = (600 - 500) / 500 = 1
P(Z< 1 ) - P(Z < - 1)
0.84134 - 0.15866
= 0.68268
= 0.68268 * 100%
= 68.268%
