B cuz we *3*3*3 to reach to n 7
Hello :
the sum is arithmetic secquence of common -diff is :
(-7)-(-5) =(-5)-(-3) = (-3)-(-1) =-2 = d
the first term is : a1 = -1
<span>the formula of the sum : S= (n/2)(a1 +an)
n is number of term an = a1+(n-1)d</span>
Answer:
Step-by-step explanation:
Given,
To give the probability that your last coin toss came up tails
the probability that the last coin toss came up tails = likelihood of occurring that all 4 were tails when coin tossed 4 times + likelihood of occurring last toss gives tail & 1st four tosses were head when coin is tossed 5 times
= (1/2)^4 + [(1/2)^5 + (1/2)^5 + (1/2)^5 + (1/2)^5]
= 1/16 + [4*(1/32)]
= 1/16 + 1/8
= 3/16
= 0.1875
Answer:
b=5.3 units
Step-by-step explanation:
area = 24 sq. ft
24 = 1/2 (bh)
h = 9
1/2(9)=4.5
24=4.5b
24/4.5 = 5.3
Answer:
C
Step-by-step explanation:
Under the translation
(x, y ) → (x + 3, y - 4 )
Add 3 to the x-coordinate and subtract 4 from the y- coordinate of the original points, that is
(- 5, 2 ) → (- 5 + 3, 2 - 4 ) → (- 2, - 2 ) → C
