Answer:
x-y=-3
Step-by-step explanation:
This is easy bro,
So first, all you have to do is finding the half circumstance,
the formula for circumstance is:
C=π*d
since the diameter is 8, therefore,
C=π*8
C=8π,
using 3.14 for π,
8*3.14=
25.12
Hope this helps!!!!
Answer: Binomial
Step-by-step explanation:
1 / 3
A binomial setting has a set number of trials, and the variable in question is the number of
successes that occur in those trials.
A geometric setting does not have a set number of trials, and the variable in question is the
number of trials it takes to get the first success.
In both settings, the trials are independent and the probability of success remains the same on
each trial.
2/3
In this game, the player rolls 7 dice, and F is the number of dice that show a 5. So the variable is
counting the number of successes
The rolls are independent, and the probability of getting a 5 is the same on each roll,
3/3
F is a binomial variable

Answer:
£191.36
Step-by-step explanation:
Sum the parts of the ratio, 1 + 4 = 5 parts
Divide 320 by 5 to find the value of one part of the ratio.
320 ÷ 5 = 64 ← value of 1 part of the ratio , thus
4 parts = 4 × 64 = 256
Thus he bought 64 first class and 256 second class.
Cost = (64 × £0.67) + (256 × £0.58)
= £42.88 + 148.48
= £191.36
