Answer:
Number of students successful= 75
Number of students not able to complete the exam in the allotted time= 5
Step-by-step explanation:
In this question the main part is missing .The given statement is the sub part of the problem .
Suppose the main part is
The time needed to complete a final examination in a particular college course is normally distributed with a mean of 80 minutes and a standard deviation of 10 minutes.
If the main part was given like this only then we could do the following calculations.
So from above the
Population mean = μ= 80
Population Standard deviation =σ= 10 mins
Sample mean = x`= 95
Sample size= n= 80
Now first we calculate the z= score
z= x`-μ/σ
z= 95-80/10= 1.5
From the z- table we find the P (z< 1.5)= 0.9332
Now we have to find the number of students who need to complete the exam in the allotted time
Number of students successful= np= 80 * 0.9332= 74.656= 75
Number of students not able to complete the exam in the allotted time= 80-75= 5
These answers are based on the main part supposed to be as added just to explain how it will be calculated.

Answer: 6 cm
Step-by-step explanation:
The surface area of the given shape is 80 cm².
From the given figure, the dimensions of large cuboid is length= 5 cm, width= 3 cm and height= 2 cm.
What is surface area of a cuboid?The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.
Formula to find the total surface area of a cuboid is 2(lw+wh+lh)
Surface area of a large cuboid
= 2(5×3+3×2+5×2)
= 2(15+6+10)
= 2×31
= 62 cm²
The dimensions of smaller cuboid is length= 1 cm, width= 1 cm and height= 4 cm
Surface area of a smaller cuboid
= 2(1×1+1×4+1×4)
= 2(1+4+4)
= 2×9
= 18 cm²
Total surface area = 62+18
= 80 cm²
Therefore, the surface area of the given shape is 80 cm².

Question 14 (5 points)
(05.02 LC)
What is the value of x in the solution to the following system of equations? (5 points)
x − 2y = 2
3x + y = 6
Answer:
x = 2 and y = 0
Step-by-step explanation:
x - 2y = 2
3x + y = 6
using the substitution method, we solve the first equation for 'x' to get
x = 2y + 2
plug that into 'x' in the second equation
3(2y + 2) + y = 6
6y + 6 + y = 6
7y = 0
y = 0
find 'x':
3x + 0 = 6
x = 6/3
x = 2
Answer:
x=2

A typical person has an average heart rate of 71.0 beats/min. Calculate the given questions. How many beats does she have in 4.0 years
Answer:
37317600 beats she will have in 4 years.
Step-by-step explanation:
Given that,
A typical person has an average heart rate of 71.0 beats/min.
We need to find the number of beats she have in 4 years.
As 1 year = 525600 min
1 min = 71 beats
525600 min = 525600 × 71
=37317600 beats
Hence, 37317600 beats she will have in 4 years.

Answer:
y = 95° and x = 21°
Step-by-step explanation:
y + 85° = 180° { being co-interior angles }
y = 180° - 85°
y = 95°
y = 4x + 11°[ being vertically opposite angles ]
95° = 4x + 11°
4x = 95° - 11°
4x = 84°
x = 84° / 4
x = 21°
