A rational number is one that can be expressed as x/y. The first statement is false. All whole numbers are rational. They can always be expressed as x/1
Some rational numbers are not whole numbers. That's true. 4/7 is rational but not whole.
Some irrational numbers are not integers. I'm tempted to say this is true.
pi is irrational and it certainly is not an integer.

Answer:
A. 18%
Step-by-step explanation:
For independent events:
P(A and B) = P(A) × P(B)
P = 0.30 × 0.60
P = 0.18
There is an 18% probability that it will rain on both days and the game will be canceled.
Answer:
All real numbers are solutions
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(2x+3)=−4(x+1)−2
Step 1: Simplify both sides of the equation.
−2(2x+3)=−4(x+1)−2
(−2)(2x)+(−2)(3)=(−4)(x)+(−4)(1)+−2(Distribute)
−4x+−6=−4x+−4+−2
−4x−6=(−4x)+(−4+−2)(Combine Like Terms)
−4x−6=−4x+−6
−4x−6=−4x−6
Step 2: Add 4x to both sides.
−4x−6+4x=−4x−6+4x
−6=−6
Step 3: Add 6 to both sides.
−6+6=−6+6
0=0

All real numbers are solutions.
Answer:
(1) 330
(2) 692
(3) 110
(4) 43.25
Step-by-step explanation:
The data provided is for the dying time of four different types of paint.
One-way ANOVA can be used to determine whether all the four paints have the same drying time.
Use Excel to perform the one-way ANOVA.
Go to Data → Data Analysis → Anova: Single Factor
A dialog box will open.
Select the data.
Select "Grouping" as Columns.
Press OK.
The output is attached below.
The required values are as follows:
(1)
Sum of Squares of Treatment (Between Subjects):
SST = 330
(2)
Sum of Squares of Error (Within Subjects):
SSE = 692
(3)
Mean Squares Treatment (Between Subjects):
MST = 110
(4)
Mean Squares Error (Within Subjects):
MSE = 43.25
Answer: One bag of peaches : $22
Step-by-step explanation:
Hi, to answer this question we have to write an equation for William and Sylvia.
- <em>William: 2 p + 3 a = 17
</em>
- <em>Silvia: 4p + 2 a =22
</em>
Where:
p = price of one bag of peaches
a= price of one bag of apricots
Solving for "a" in William's equation:
2p +3a =17
3a = 17-2p
a = (17-2p)/3
a= 17/3 -2/3 p
Replacing "a" in Silvia's equation
4p + 2 a =22
4p + 2 (17/3 -2/3p) =22
4p +34/3-4/3p =22
4p-4/3p =22-34/3
8/3 p =32/3
p =32/3 ÷8/3
p=4
