This is simple:
If k=3/5, then you substitute 3/5 for k
Example:
5(3/5)(-7)=?
Answer: -175/3 or -58.33 repeating
Answer:
1. 3/5=60%
2. 4 remaining in the bag
3. 2 marbles remain in the bag
4. 2/4=1/2=50%
Answer:
Step-by-step explanation:
The volume of a rectangular prism is calculated multiplying the area of the prism times the height of the prism.
The area of the base of your prism is 4 3/4 ft2, so you are going to multiply it times the height that is 2 1/3 ft.
The result must be: 11.07 ft³
Answer: x = 4.6
Step-by-step explanation:
From the diagram opposite is 4
Adjacent is x
@ = 41 degrees.
Solve from SOH CAH TOA
From here the one that has opposite and adjacent is TOA which is;
[email protected] = opposite/ adjacent
[email protected] = 4/x
x = 4/[email protected]
x = 4/tan 41
x = 4/0.869
x = 4.6
Answer:
The probability that more than a third of the buyers would prefer brown is 0.8491.
Step-by-step explanation:
This is binomial problem with n=15 and p=0.50.
The binomial formula of probaility is:
P(X=x)=
More than a third of the buyers: 15÷3=5
We have to find P(x>5).
P(x>5) = 1 - P(x≤5) = 1 - P(x=0) - P(x=1) - P(x=2) - P(x=3) - P(x=4) - P(x=5)
P(x=0)=
=0.00003
P(x=1)=
=0.00046
P(x=2)=
=0.00320
P(x=3)=
=0.01389
P(x=4)=
=0.04165
P(x=5)=
=0.09164
P(x>5) = 1 - P(x≤5)= 1- 0.00003 - 0.00046 - 0.00320 - 0.01389 - 0.04165 - 0.09164 = 0.8491
