Answer: B. Probability
For example, let's say you want to know the probability of flipping tails.
There's 1 way to get tails out of 2 sides total. So 1/2 = 0.5 is the probability of flipping tails.
We define "success" as "getting tails".
A. Find the unknown term of each proportion.
1. Answer: X=5
Step-by-step explanation:
x/7=15/21 ==> 21x=7(15) ==> 21x=105
21x/21=105/21 ==> x=5
2. Answer: X=40.5
Step-by-step explanation:
27/x=x/3 ==> 27(3)=x(x) ==> 81=2x
81/2=2x/2 ==> x=40.5
3. Answer: X=16
Step-by-step explanation:
8/x+2=4/9 ==> 8(9)=4(x+2) ==> 72=4x+8
72-8=4x+8-8 ==> 64=4x ==> 64/4=4x/4 ==> x=16
4. Answer: X=8
Step-by-step explanation:
3/x=30/80 ==> 3(80)=30x ==> 240=30x
240/30=30x/30 ==> x=8
5. Answer: M=56
Step-by-step explanation:
m/8=m+7/9 ==> 9m=8(m+7) ==> 9m=8m+56
9m-8m=8m-8m+56 ==> m=56
B. Solve the following.
1. Answer: 80 and 100
Step-by-step explanation:
4:5 ==> 4x+5x=180 ==> 9x=180
9x/9=180/9 ==> x=20
4(20)= 80 5(20)=100
2. Answer: 235.29
Step-by-step explanation:
3400/8 ==> 425
100,000/425= 235.29
Kilo, for kilogram is the best to use for easuring the mass of a person. 1 Kilogram (Kg) = 1000 grams. For example, I have 60 kilograms (132.27 pounds).
Mili is used for very small quantities (Mili = 1/1000 grams). Deci = 1/10 grams and deca 10 kilograms = 10.000 grams. Good luck !
Answer:
y = 4, x = -5
Step-by-step explanation:
We can solve for x
We can then substitute it into the second equation
y = 4, so we can plug that back into the first equation:
We can double check:
Since it is true, we know it works
<span>Equations:
x + y = 5000
3x + 3.5y = 15500
------
30x + 30y = 150000
30x + 35y = 155000
-----------------------
5y = 5000
----
y = $1000.00 (amt invested at 3.5%)
---
x = $4000.00 (amt. invested at 3%)
