second-period class average:
55+70+450+480+170+270+95 = 1590
1590/20 = 79.5
sixth-period class average:
65+225+480+595+270+190 = 1825
1825/20 = 91.25
on average, students in the sixth period class scored higher
Answer: y - 9 = 2(x - 5)
Step-by-step explanation:
Point slope form: y - y1 = m(x - x1)
substitute 5 for x1 and 9 for y1 and 2 for m
x1 = 5
y1 = 9
m = 2
you get y - 9 = 2(x - 5)
The probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixt
<h3>What is probability?</h3>
Probability is the likelihood or chance that an event will occur. Mathematically;
Probability = Expected/Total
If the spinner is spinned, the total outcome is 1/6
Pr(greater than 4) = 2/6 = 1/3
Pr(shaded section) = 3/6 = 1/2
Pr(number greater than 4 or on a shaded section) = 1/3 + 1/2
Pr(number greater than 4 or on a shaded section) = 5/6
Hence the probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixths
