Answer:
Option c. is correct
Step-by-step explanation:
The standard deviation is a measure of the amount of dispersion in a set of values.
Mean of a normal distribution (m) = 154
Standard deviation (s) = 15
z-score = 2.2
To find: value (x) that has a z-score of 2.2
z-score is given by
Put
Option c.is correct
Both of the first two choices represent the amount Connor paid.
15% = 0.15, so when you subtract 15% of d from d, you get the 2nd expression. When you simplify that, you get the 1st expression.
The correct choices are ...
• 0.85d
• d - 0.15d
The point will be at (-1, 3). Use the x value that has only been used once, -1, and the y value that has only been used once. (6,0) and (6, 3) are on the same side vertically of the rectangle because their x values are the same. Because 6 > -1, you know that they make up the right side of the rectangle. (-1,0) and (6, 0) both have the same y values, so they are on the same side horizontally, and are the bottom of the rectangle because 0<3. This all means the fourth point is the rectangles's top left corner. Because it is a rectangle, its sides are parallel, so you know that it will have the same x value as the left bottom point (-1,0) and the same y value as the right top point, (6, 3).
Answer:
The volume of water in the pool is 1320 feet³ .
Step-by-step explanation:
Formula
Volume of a rectangular prism = Length × Breadth × Height
As given
A pool in the shape of a rectangular prism is being filled with water.
The length and width of the pool is 24 feet and 15 feet. If the height of the water in the pool is feet.
Length = 24 feet
Breadth = 15 feet
Put all the values in the above formula
Volume of water in the pool = 1320 feet³
Therefore the volume of water in the pool is 1320 feet³ .
General form of vertex of a parabola is
y = a(x - b)^2 + c where vertex = (b , c)
for this equation the vertex is at (-1,0).
the axis of symmetry is x = -1
