If the temperature at which a certain compound melts is a random variable with mean value 120 ???? ???? and standard deviation 2

bogdanovich [222]

Answer:
Temperature is measured in units of temperature.
In SI units, it is K (degrees Kelvin).
In CGS units, it is °C (degrees Celsius)
In English units, it is °F (degrees Fahrenheit)

Therefore the mean and standard deviation will be measured in the selected units for temperature.

Solve each given equation and show your work. Tell weather each equation has one solution, an infinite number of solutions, or n

galben [10]

Hello!

To solve algebraic equations, you need to SADMEP it. SADMEP is only used to solve these equations, and it is an acronym for subtraction, addition, division, multiplication, exponents, and parentheses. The goal here is to get x on one side of the equation.

(a) 4x + 2(x - 1) = 10 + 2x (use the distributive property)

4x + 2x - 2 = 10 + 2x (add alike terms)

6x - 2 = 10 + 2x (subtract 2x from both sides)

4x - 2 = 10 (add 2 to both sides)

4x = 12 (divide both sides by 4)

x = 3

This equation has one solution because if you substitute 3 for x into the original equation, then both sides of the equation will be equal.

(b) 30 - x = 10 + -1(6x + 10) (use the distributive property)

30 - x = 10 + -6x - 10 (simplify)

30 - x = -6x (add x to both sides)

30 = -5x (divide both sides by -5)

x = -6

This equation has one solution because if you substitute x = -6 into the given equation, then the left and right side of the equation will be equivalent to each other.

(c) 8x = 4x + 4x + 10(x - x) (simplify - add and subtract)

8x = 8x + 10(0) (multiply)

8x = 8x

This equation has an infinite number of solutions because if you substitute any number into the given equation, both sides of the equation will be equal.

A baseball pitcher throws a fastball 60.5 feet in 2 seconds. If the ball travels at a constant speed per second, how can you wri

valentina_108 [34]

Given that:

Miles traveled the fastball in 2 seconds = 60.5 ft

So, the ball traveled in one second

$\begin{gathered} =\frac{\text{Miles traveled in 2 seconds}}{2} \\ =\frac{60.5}{2} \\ =30.25 \end{gathered}$

The ball travels 30.25 miles per second.
