Answer:The numbers are 8 1/3, 9 1/3, and 10 1/3
Step-by-step explanation:
Answer:
BC≈8,38
Step-by-step explanation:
AB=a
BC=c
CA=b
a²+b²=c²
3.3²+7.7²=c²
√70,18=√c²
c≈8,38
Answer:
The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.
I guess that we want to find the expected value in one spin:
number 1: wins $1
number 2: wins $3
number 3: wins $5
number 4: wins $7
number 5: losses $8
number 6: loses $8
The expected value can be calculated as:
Ev = ∑xₙpₙ
where xₙ is the event and pₙ is the probability.
We know that the probability for all the events is 1/6, so we have:
Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0
So the expected value of this game is $0, wich implies that is a fair game.
Answer:
m = 55/8 = 6.875
Step-by-step explanation:
Step by step solution :
Step 1 :
7
Simplify —
8
Equation at the end of step 1 :
7
6 - (m - —) = 0
8
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 8 as the denominator :
m m • 8
m = — = —————
1 8
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Question
What is the simplified expression for Negative 3 c d minus d (2 c minus 4) minus 4 d?
a) Negative 5 c d
b) c d minus 8 d
c) 5 c d minus 8 d
d) Negative 5 c d minus 8 d
Answer:
a) Negative 5cd or -5cd
Step-by-step explanation:
The question asks:
What is the simplified expression for Negative 3 c d minus d (2 c minus 4) minus 4 d?
This is expressed mathematically as:
-3cd - d(2c - 4) - 4d
= -3cd -2cd + 4d - 4d
= -5cd + 0
= -5cd
The answer is negative 5cd(in words) or - 5cd
