Math. When no number occurs more than once in a data set, there is no mode. If each of two numbers occurs twice, we say the set is bimodal.
7P2, so 42 ways - permutation method since the order of choosing matters (chair and vice chair)
Answer:
1.33
Step-by-step explanation:
62 can only be subtracted from 82 once. So 82.46-62 would be 20.46. Since you can't subtract anymore you put a decimal point. 62x3=186 and 20.46-186=1.86 and you can subtract 186-186=0.
Answer:
Step-by-step explanation:
Jacket multiplied by 20 percent
$120.00 x .20 = 24
Jacket minus the answer
$120 - 24 =96
New cost of jacket is $96
Now multiply that by 6.25% tax
$96 x 6.25 = 6.00
Add the sales tax to cost of jacket
$96.00 + 6.00 = $102.00
49–2ax –a^2–x^2
Extract the negative sign
= 49 - (a^2 +2ax +x^2)
Factor using a^2 + 2ab + b^2 = (a+b)^2
= 49 - (a+x)^2
Factor using a^2 - b^2 = (a-b)(a+b)
= ( 7- (a + x)) * (7 + (a + x))
= ( 7- a - x) * (7 + a + x)
