The mean is just the multiplication of [tex]n[/tex] and [tex]p[/tex] so [tex]60 * 0.3[/tex] = [tex]18[/tex]
Variance is [tex](1 - p) * n * p[/tex] so [tex]0.7 * 60 * 0.3 = 12.6[/tex]
So the variance is [tex]12.6[/tex]
The standard deviation is just the root of the variance so: [tex]\sqrt{12.6}[/tex] = [tex]3.55[/tex] rounded to the nearest hundredth. :D

6y+4−3y−7=3(y−1) How many solutions are for this?
Answer:
Infinite amount of solutions.
General Formulas and Concepts:
Order of Operations: BPEMDASRegular + Equality PropertiesStep-by-step explanation:
Step 1: Define equation
6y + 4 - 3y - 7 = 3(y - 1)
Step 2: Solve for y
Combine like terms: 3y - 3 = 3(y - 1)Distribute 3: 3y - 3 = 3y - 3Subtract 3y on both sides: -3 = -3Here we see that there will be infinite amount of solutions. We can plug in any number y and it will render the equation true.

Find three consecutive odd integers such that the sum of 7 times the smallest and twice the largest is -91.
The length of Joe's arm is 28 inches. The length of his lower arm is 21 inches. What percent of Joe's arm is his lower arm?
Answer:
75%
Step-by-step explanation:
You take the length of the lower arm, 21, and divide it by the total length, 28. Your equation should be 21/28 = 3/4 =.75. 0.75 is equal to 75%

Solve by finding square roots
4 (x-1)^2=96
Answer:
2√6 + 1
Step-by-step explanation:
Given expression:
4(x-1)² = 96
Solving by square root;
Square root both sides;
[tex]\sqrt{4(x-1)^{2} }[/tex] = √96
√4(x-1)² = √6x16
√4(x-1)² = 4√6
2(x-1) = 4√6
Divide both sides by 2;
x-1 = 2√6
Add 1 to both sides;
x = 2√6 + 1

A parent is using a garden hose to fill up a small inflatable pool for her young child. The pool has a capacity of 90 gallons. She turns the water off after 5 minutes, but leaves the hose in the pool for another 3 minutes before putting it away.
In this situation, the relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function.
In that function, which variable is independent? Which one is dependent?
Type your response in the space below.
Answer:
Independent variable = the time. Dependent variable = amount of water per minute
Step-by-step explanation;
The total amount of water depends on how long the hose is left on.
The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.
Time is the independent variable.
The amount of water per minute is the dependent variable.
Given
A parent is using a garden hose to fill up a small inflatable pool for her young child.
The pool has a capacity of 90 gallons.
She turns the water off after 5 minutes but leaves the hose in the pool for another 3 minutes before putting it away.
What is the independent variable?Independent variables are the variables that the experimenter changes to test their dependent variable.
What is the dependent variable?A change in the independent variable directly causes a change in the dependent variable.
1. The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.
2. Time is the independent variable.
3. Amount of water per minute is the dependent variable.

Answer: 7 2/3
Step-by-step explanation: got it wrong and it showed me the right answer on khan academy
The volume of the rectangular prism is 23/3 units³.
We need to find the volume of the following rectangular prism.
What is the formula to find the volume of the rectangular prism?The formula to find the volume of the rectangular prism is Volume=l×b×h.
Now,
Height of the rectangular prism = 4/3 units
Area of one of the surfaces of the rectangular prism = 23/4 units²
The volume of the rectangular prism = 4/3 units × 23/4 units²
= 23/3 units³
Therefore, the volume of the rectangular prism is 23/3 units³.
