One such pair is 1/4 and 3/4
1/4 + 3/4 = (1 + 3)/4 = 4/4
= 1
Answer:
60 degrees
Step-by-step explanation:
EF and DC have lines through them indicating that they are equal in length, telling us that the figure is an isosceles trapezoid. Congruent base angles are a property of isosceles trapezoids, like isosceles triangles. This means that the base angles C and F will have the same measure. The measure of angle F is 60 degrees, therefore the measure of angle C will also be 60 degrees.
hope this helps :)
Answer:
(x - 16)² + (y - 4)² = 8
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (16, 4) and r = 2
, thus
(x - 16)² + (y - 4)² = (2 )², that is
(x - 16)² + (y - 4)² = 8
Answer:
4
Step-by-step explanation:
Class width is said to be the difference between the upper class limit and the lower class limit consecutive classes of a grouped data. To calculate class width, this formula can be used:
CW = UCL - LCL
Where,
CW= Class width
UCL= Upper class limit
LCL= Lower class limit
From the table above:
For class 1, CW = 64 - 60 = 4
For class 2, CW = 69 - 65 = 4
For class 3, CW = 74 - 70 = 4
For class 4, CW = 79 - 75 = 4
For class 5, CW = 84 - 80 = 4
Therefore, the class width of the grouped data = 4
