oh, come on. you can just use common sense.
a local minimum is a point where the curve goes down to, and then turns around and starts to go up again. that point in the middle, where it turns around and does not go down any further, is the minimum.
for the maximum the same thing applies, just in the other direction (the curve goes up and turns around to go back down again).
a)
the local minimum values (y) are
-2, -1
b)
the values of x where it had these minimum values are
-1, +3
The following box plot shows the number of years during which 24 schools have participated in an interschool swimming meet:
At least how many schools have participated for 1 year or less? (5 points)
6 schools
8 schools
12 schools
14 schools
The number of schools have participated for 1 year or less are below the first quartile, which is: A. 6 schools.
What is the First Quartile in A Box Plot?The first quartile marks the 25th data point of a data distribution (1/4) and is represented at the beginning of the edge of the rectangular box in a box plot.
Using the box plot given, 1 year is the first quartile mark on the box plot. So, the schools that participated for 1 year or less is 1/4 of the total schools. That is:
1/4 × 24 = 6 schools.

Hey there!
Answer :x = -1 or x = -8 ✅
Explanation :To solve this equation, you have to use the zero product property.
↳ Ifa product of factors is zero, then at least one of its factors is zero.
Which means that either x + 1 = 0 or x + 8 = 0
⇒ x + 1 = 0
Subtract 1 from both sides :
⇒ x + 1 - 1 = 0 - 1
⇒ x = -1
OR
⇒x + 8 = 0
Subtract 8 from both sides :
⇒x + 8 - 8 = 0 - 8
⇒x = -8
Therefore, x = -1 or x = -8.

Surface Area = 44 square feet
Double width = Double the space
Step-by-step explanation:
Please see attached explanations.
Surface area is the area (one side multiplied by another) of every side of the storage box, added together.
I have labeled each unique pair of sides as a, b, and c. That is top and bottom, left and right side, and front and back side.
Volume is the length multiplied by the width multiplied by the height.
By doubling the width, you are doubling the size of the box in that given direction. You can prove this mathematically by making the width twice of what it was and finding volume again.

Answer:
9-pack
Step-by-step explanation:
Price per roll for 4-pack = Pack price / Number of rolls in pack
= 2.25 / 4
= £0.56 (rounded off to nearest cent)
Price per roll for 9-pack = Pack price / Number of rolls in pack
= 4.50 / 9
= £0.50
From here, we can see the 9-pack is of better value.
