Answer:
m=-12
Step-by-step explanation:
Not sure where the 8 comes from, but you would subtract 9 from the left side. The result is -12.
Answer:
20
Step-by-step explanation:
AB = √(-4)² + (-3)²
AB = √ 16 + 9
AB = √ 25
AB = 5
AD = 4 ; DC = 4 ; BC = 7
Perimeter = 5 + 4 + 4 + 7 = 20 units
Answer:
- This is a biased sampling method for obtaining customer opinions because those who take the time to write an online review are likely to do so because they are upset with the service they received.
- The direction of the bias is likely to overestimate the proportion of customers who have a negative opinion on the service.
Step-by-step explanation:
1) There are groups which are not represented in the survey like those who don't use web. And also those who take the time to write an online review are likely to do so because they are upset with the service they received.
2) Those who had negative experience are more likely to write a review than those who had not.
2 is a multiple of 4, so anything that's a multiple of 4 will automatically be a multiple of 2
so 3 x 4 = 12
so multiples of 12 that are between 67 and 113 are...?
12 x 6 = 72
12 x 7 = 84
12 x 8 = 96
12 x 9 = 108 <span> 72 or 84 or96 or 108
all are divisible by 2,3 and 4
all fall between 67 and 112</span>
45 ÷ 3 = 15
21 ÷ 3 = 7
12 ÷ 3 = 4
(4 + 15) x 7 = 133
OR if you’re using bedmas/pedmas
4 + (15 x 7) = 109
