Answer: 155°
because ∠a and ∠c are 2 opposing angles => m∠a = m∠c = 155°
Step-by-step explanation:
Answer:
I . class width is 3
ii. Class midpoints are 33,36,39,42,45,48,51.
iii. Class boundaries are: 31.5-34.5, 34.5-37.5, 37.5-40.5, 40.5-43.5, 43.5-46.5, 46.5-49.5, 49.5-52.5
Step-by-step explanation:
I. The class width is the difference between upper class boundary and lower class boundary.
ii. Class midpoints is the summation of upper and lower class limits, divided by 2.
iii. Class boundaries is the subtraction of 0.5 from the lower classe limits and the addition of 0.5 to upper class limits.
Answer:
9/50
Step-by-step explanation:
Turning 18% to a decimal= .18. As you turn the decimal to a fraction, it gives you 9/50
9/50= .18
Answer:
13
Step-by-step explanation:
Take any two corresponding values, say (3,7) and (9,16)
Calculate the gradient of the linear function
Gradient=[16-7]/[9-3]=9/6=3/2
find the equation or rule of the linear mapping
y-7=(3/2)(x-3)
y=3x-9+7
y=(3/2)x+5/2
Answer:
Option B) is incorrect
Step-by-step explanation:
Looking at the graph the following points are to be noted.
<em>1) the graph has one maximum and one minimum within the interval.</em>
<em>2)the maximum value is attained at x=8, f(x) = 70</em>
<em>3)The least minimum value attained is at x=0, f(x) = -18</em>
<em>4) the y intercept is attained at x=0, f(x) = -18 ( thus option A is correct)</em>
as the graph decreases then increases within(3,6) and increases then decreases within (1,3) , so options A and D are correct.
And from above option B is wrong
