Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm. If all the scoops are evenly distributed, they would all be 3.8 cm tall.
<h3>How to find the mean value of a data set?</h3>
The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.
If the data set consists of values
x_1, x_2, ..., x_n
, then we get the mean value as:

The baker needs to use 100/3 pounds of 90% chocolate to make the cake.
<h3>
Equation </h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the amount of 90% chocolate. Using equation:
100 * 70% + x * 90% = (x + 100) * 75%
100 * 0.7 + 0.9 * x = (x + 100) * 0.75
70 + 0.9x = 0.75x + 75
x = 100/3
The baker needs to use 100/3 pounds of 90% chocolate to make the cake.

Answer:
x = y/2 - 1/2
Step-by-step explanation:
you can use the slope-intercept form of a line first, then change to terms of 'x'
y = mx + b where 'm' is the slope and 'b' is the y-intercept
if we use two points on the line, such as (-1, -1) (0, 1), we can find the slope
m = 1-(-1) / 0-(-1)
m = 2/1
b = 1
Slope-Intercept form: y = 2x + 1
in terms of 'x':
2x = y - 1
x = y/2 - 1/2
