Answer:
P(at least one tail) = 7/8
Step-by-step explanation:
If you flip a coin, you have two outcomes- heads or tails. So let's find all the outcomes for flipping three coins.
H = heads. T = Tails
HHH P(what you want) = <u>number of times it happens</u>
HHT Total number of outcomes.
HTH
HTT P(at least one tail) = <u> 7 </u>
THH 8
THT
TTH
TTT
Answer:
-3, 5/2
Step-by-step explanation:
What are the roots of the function y = 4x2 + 2x – 30?
To find the roots of the function, set y = 0. The equation is 0 = 4x2 + 2x – 30.
Factor out the GCF of : 2, so the equation becomes 0 = 2(2x2+x-15)
Next, factor the trinomial completely. The equation becomes: 0=2(x+3)(2x-5)
Use the zero product property and set each factor equal to zero and solve.
x+3=0 2x-5 = 0
x = -3, 5/2
The roots of the function are -3, 5/2.

For this case we have the following relationship between the volumes:
Where,
V2: Volume of the triangular prism after applying the scale factor on each side
V1: Original volume of the triangular prism
k: scale factor
Substituting values we have:
Rewriting:
Answer:
the volume of the prism if each side is dilated by a factor of 1/3 will be
V = 1 cubic unit
Answer:
the answer is b
Step-by-step explanation:
so you can see the points 1,12 amd 2,17 and you want to find how much this goes up by because it is an arithmetic sequance. so if you go up by 5 everytime then the y-intercept where the line crosses the y-axis would be 0,7 or 7
