A glass vase factory recently produced 4 vases that were chipped and 16
vases that were not. Considering this data, how many of the next 10 vases
would you expect to be chipped?
Answer:
2
Step-by-step explanation:
4 chipped + 16 not chipped = 20 total
4 / 20 = 1/5 or 20% chance that vase will be chipped
Set up a proportion or find 20% of 10.
[tex]\frac{1}{5} = \frac{x}{10}[/tex] x = 2 (ten is on denominator because it's the total amount of vases)
or 10 * 0.2 = 2
A pool is surrounded by a rectangular fence with a
perimeter of 72 yards. If the length of the fence is 3
times the width, what is the length of the fence, in yards?
Answer:
width is 33
Step-by-step explanation:
width (b) =?
length(l)=3
perimeter (p)=?
now,
perimeter = 2(l+b)
or,72= 2(3+ b)
or,72/2= 3+b
or,36= 3+b
or,36-3= b
or,33= b
therefore width is 33

Shawn designs a rectangular garden as shown below. He will design both rock sections to have the same width (x).
The area in, square feet, of Shawn’s garden is found be calculating 15(2x + 7). Shawn incorrectly says the area can also be found using the expression 30x + 7.
Describe the error in Shawn’s expression. As part of your explanation, find the difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression.
Answer:
a) Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7
b) The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as
98 square feet
Step-by-step explanation:
The area in, square feet, of Shawn’s garden is found be calculating 15(2x + 7). Shawn incorrectly says the area can also be found using the expression 30x + 7.
The correct area =
15(2x + 7).
= 30x + 105 square feet
The error in Shawn’s expression is
= 15(2x + 7)
= 30x + 7 square feet
Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7
The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as
30x + 105 square feet - 30x + 7 square feet
= 30x + 105 - (30x + 7)
= 30x - 30x + 105 - 7
= 98 square feet

WILL GIVE BRAINLIEST, PLEASE EXPLAIN J=HOW TO FIGURE THIS PROBLEM OUT THANK YOU. The figure below shows a shaded region and a non-shaded region. Angles in the figure that appear to be right angles are right angles.
A picture of a rectangle is shown. The bottom of the rectangle is labeled 16 ft. The right side of the rectangle is labeled 8 ft. At the bottom left side of the rectangle there is a label that reads 2 ft. Inside the rectangle is a shaded region. The bottom of the region is labeled 8 ft and this side is perpendicular to the left side of the rectangle. The right side of the shaded region has a perpendicular line segment extending upward that is labeled 2 ft. At the top of this line segment is another line segment perpendicular to the right that reads 2 ft. At the end of this line segment is a perpendicular line segment extending upward that reads 1 ft. There is a line segment joining the end of this line segment with the top left corner of the rectangle.
What is the area, in square feet, of the shaded region?

write the slope intercept form of the equation of each line
Answer:
Y= - 1/5x-4
Step-by-step explanation:
slope intercept form: y=mx+b
Slope formula: rise/run
(5,-5) AND (0,-4)
-5+-4= -1
5+0= 5 AKA - [tex]\frac{1}{5}[/tex] or -1/5
The m in y=mx+b is the slope, the equation above is the sloe formula meaning -1/5 is the slope. The b is the y, when it is at 0. The y at 0 for this equation is -4. Thus, when plugging in the equation, y=-1/5x-4

Find the midpoint of AC is at -2 and C is at 3 on a number line
The value of midpoint of AC will be 0.5.
What is Number line?Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Given that;
Point A is at - 2 and C is at 3 on the number line.
Now,
Since, Point A is at - 2 and C is at 3 on the number line.
Hence, The midpoint of AC = (- 2 + 3 ) / 2
= 1/2
= 0.5
Thus, The midpoint of AC = 0.5
