This is a ratio problem. First, we need to add the number of students polled.
7 + 4 + 3 + 6 = 20
Next, look at how many out of 20 students selected Science.
3 out of 20.
Say it this way:
3 is to 20 as ? is to 400.
Express it this way:
3/20 = x/400
Cross multiply to eliminate the denominators.
3 x 400 = 20 x Now solve for x.
1200 = 20 x
x = 60
Check it!
Does 60/400 reduce to 3/20? Yes!
60 students are predicted to select science out of 400
Answer: D) It has no slope because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the denominator of a fraction cannot be zero.
Step-by-step explanation:
slope is y2-y1/x2-x1
20-10/7-7
10/0
denominator can't be 0
Answer:
angle BCD = 108
Step-by-step explanation:
opposite angles in a cyclic quadrilateral add to 180
so angle BDC is 180 - 72 = 108
what are the angles 32 and 114 there for??
