Answer:
ima say C
Step-by-step explanation:
its really the only one that makes sense in the situation.
There will be 4 water stations.
Why?
3/4 = .75 as a decimal
Personally, I believe that it’s easier to use decimals, I can explain the way in fractions in the comments if you’d like, just ask.
Anyway, .75 • 4= 3
or 3 / .75 = 4 (division is easier with bigger numbers)
so, there will be 4 water stations, given that the one race is 3 miles long.
If this explanation seems unclear, I’d be happy to explain. Feel free to ask in the comments!! I’m happy to help.
Hope this helps!

Answer:
a) 0.00031
b) 0.0017
c) 0.31
d) 0.00018
Step-by-step explanation:
attached below is the detailed solution
Total number of 7-poker cards are 52P7 = 133784560
A) Determine the probabilities of Seven-card straight
probability of seven-card straight = 0.00031
B) Determine the probability of four cards of one rank and three of a different rank
P( four cards of one rank and three of different rank ) = 0.0017
C) Determine probability of three cards of one rank and two cards of each two different ranks
P( three cards one rank and two cards of two different ranks ) = 0.31
D) Determine probability of two cards of each of three different ranks and a card of a fourth rank
P ( two cards of each of three different ranks and a card of fourth rank ) = 0.00018
Answer:
a = <u>76°</u>
b = <u>124°</u>
Step-by-step explanation:
Since the lines are parallel, we can prove that the smaller triangle's missing angle (shares a line with ∠b) is 56°.
180-56=124°
∠b=124°
Now to find Angle A:
180-56-48=
124-48=
76°
∠a=76°
So the area the circle is 615.44 and the equation to solve it is 2(3.14)r^2
