Answer:
Point E on the number line represents the approximate volume of a cylinder with a radius of 4 units and height of 4 units.
Step-by-step explanation:
It is given that the radius of the cylinder is 4 units and the height of the cylinder is 4 units.
The volume of the cylinder is
Where, r is radius and h is height of the cylinder.
Substitute r=4, h=4, π=3.14 in the above formula.
The volume of the cylinder is 200.96. Therefore, point E on the number line represents the approximate volume of a cylinder with a radius of 4 units and height of 4 units.
The information above is shown in the normal distribution curve shown below
Step 1 : Find the z-score for 5 hours
rounded to 2 dp
Step 2: Read the value of z-score on the z-table
As shown in the second picture, the value z at -1.18 is 0.1190
Step 3: The proportion can be written in percentage form which is 11.90% rounded to 12% to nearest whole number
Answer:
33.94 CM
Step-by-step explanation:
To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape.
Let x = the smaller number
Let 2x + 7 = the larger number
x + 2x + 7 = 25
3x = 18
x = 6
2x + 7 = 2(6) + 7 = 19
Answer:
They are parallel lines
Step-by-step explanation:
Firsr you have to put both of the equations in slope intercept form which is y=mx+b and line 1 that would be 4y=3x+12 then you divide the slope and the y-intercept by 4 to get ride of the 4 in front of the y and it would equal y=3/4x+3 and for line 2 you do the same and that put into slope intercept form would be 2y=1.5x-14 so you do the same and divide the slope and the y-intercept by 2 which would equal y=0.75x-7 and 3/4 in decimal form would be 0.75. since the slopes are the same the lines would be parallel
