Answer:
52.38%
Step-by-step explanation:
P(991<X<997) = normalcdf(991,997,993,4) = 0.5328, therefore, about 52.38% of the bottles have volumes between 991 mL and 997 mL
Answer:
x=5, y=1
Step-by-step explanation:
Isolate x for 5x-3y=22
5x-3y=22
Add 3y to both sides
5x-3y+3y=22+3y
Simplify
5x=22+3y
Divide both sides by 5
5x/5=22/5+3y/5
Simplify
x=22+3y/5
Substitute x=22+3y/5
10*22+3y/5-4y=46
Simplify 10*22+3y/5-4y
10*22+3y/5=2(3y+22)
=2(3y+22)-4y
Expand 2(3y+22)
=6y+44-4y
Simplify 6y+44-4y
=2y+44
Isolate y for 2y+44=46
2y+44=46
Subtract 44 from both sides:
2y+44-44=46-44
Simplify
2y=2
Divide both sides by 2;
2y/2=2/2
Simplify;
y=1
For x=22+3*1/5 substitute y=1
y=22+3*1/5
22+3*1=25
=25/5
Divide the numbers;25/5=5
=5
x=5
The solutions to the system of equations are;
x=5, y=1
The maximum rate, r, that the scuba diver may descend is r≤ 11.2
Given the following parameters:
- Initial length = 14.7feet
If the scuba diver reaches a depth no more than 65.1 feet below sea level, then;
r ≤ (65.1 - 14.7)/4.5
r≤ 50.4/4.5
r≤ 11.2
Hence the maximum rate, r, that the scuba diver may descend is r≤ 11.2

Answer: p = 1/5
Step-by-step explanation:
-5(p + 3/5) = -4
Now we open the brackets and -5 mutiplies with both terms
-5p - 3 = -4
-5p = -4+3
-5p = -1
p = -1/-5
p = 1/5
