Answer:
68% of the distribution will be within one standard deviation of the mean
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
Bell-shaped = Normally distributed.
This means that 68% of the distribution will be within one standard deviation of the mean

Need all the work shown too solve for X
Answer:
X = 5
Step-by-step explanation:
28 = 7x + 3 - 2x
28 = 5x + 3
28 - 3 = 5x + 3 - 3
25 = 5x
25/5 = 5x/5
X = 5
Answer:
X = 5
Step-by-step explanation:
1. Combine like terms.
2. Subtract 3 from both sides.
3. Simplify.
4. Divide both sides of the equation by the same term.
5. Simplify.

Micah has three 6-foot-long sandwiches. He needs to cut pieces that are 8 inches long from the sandwiches. What is the greatest number of 8-inch pieces he can cut from the three sandwiches?
Answer:
27 pieces
Step-by-step explanation:
1) first, multiply 6 times 3 (6×3=18)
2) 1 ft = 12 in. so you multiply the 18 by 12 (18×12=216)
3) now you divide the 216 by 8 (216÷8=27)

What is the value of x?
NOTES: The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown."
Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Answer:
-4 and 8
Step-by-step explanation:
-4 x 8 = -32
-4 + 8 = 4
The two numbers that multiply to -32 and add up to 4 are -8 and 4.
To find two numbers that multiply to -32 and add up to 4, we can use a factoring approach or trial and error.
Let's consider two numbers, x and y, such that:
xy = -32 (Equation 1)
x + y = 4 (Equation 2)
We need to find values of x and y that satisfy both Equation 1 and Equation 2 simultaneously.
By trying different pairs of numbers, we can find that -8 and 4 satisfy both equations:
-8 * 4 = -32 (Equation 1)
-8 + 4 = 4 (Equation 2)
Therefore, the two numbers that multiply to -32 and add up to 4 are -8 and 4.

Answer:
y-intercept: -5
Slope: 4
Equation: y = 4x - 5
Step-by-step explanation:
✔️ y-intercept (b):
When x = 0, y = -5. Therefore, the y-intercept (b) = -5. It is the point at which the y-axis cut across by the line. At this point, x is always zero.
✔️Slope using two points (0, -5) and (1, -1):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-1 - (-5)}{1 - 0} = \frac{4}{1} = 4 [/tex]
Slope (m) = 4
✔️Equation in slope-intercept form y = mx + b:
Substitute m = 4, and b = -5 into y = mx + b
y = 4(x) + (-5)
y = 4x - 5

What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
2x + 4x + 5 = 7 is an equation.
We have,
49x + 9 = 49x + 83
Solving for x we get,
49x + 9 = 49x + 83
Subtract 49x on both sides.
9 = 83
This is not true.
This condition is a system of equations where there are no solutions.
Thus,
The equation 49x + 9 = 49x + 83 has no solutions.
