Answer:
3
Step-by-step explanation:
if you use rise/run from (-2,0) you can see a positive slope of 3
- The correct statements are:
the weights of the pineapples in crate 1 were the most variable. - The heaviest pineapple was in crate 1.
- More than half the pineapples in crate 1 and crate 3 were heavier than the heaviest pineapple in crate 2.
<h3>What are the correct statements?</h3>
A box plot is used to study the distribution and level of a set of scores. The box plot consists of whiskers which measure the minimum and maximum numbers. The difference between these numbers is the range which measures variability.
On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile. The difference between the first quartile and the third quartile is the interquartile range.
For the first box plot:
- Minimum number = 1.5
- Range = 6 - 1.5 = 4.5
- Median = 4
- First quartile = 3
- Third quartile = 4.5
- IQR = 4.5 - 3 = 1.5
For the second box plot:
- Maximum number = 3.5
- Minimum number = 1
- Range = 3.5 - 1 = 2.5
- Median = 2
- First quartile = 1
- Third quartile = 2.5
- IQR = 2.5 - 1 = 1.5
For the third box plot:
- Maximum number = 5
- Minimum number =2.5
- Range = 5 - 2.5 = 2.5
- Median = 4
- First quartile = 3.5
- Third quartile = 4.5
- IQR = 4.5 - 3.5 = 1

Remember that the vertex form of a parabola or quadratic equation is:
y=a(x-h)^2+k, where (h,k) is the "vertex" which is the maximum or minimum point of the parabola (and a is half the acceleration of the of the function, but that is maybe too much :P)
In this case we are given that the vertex is (1,1) so we have:
y=a(x-1)^2+1, and then we are told that there is a point (0,-3) so we can say:
-3=a(0-1)^2+1
-3=a+1
-4=a so our complete equation in vertex form is:
y=-4(x-1)^2+1
Now you wish to know where the x-intercepts are. x-intercepts are when the graph touches the x-axis, ie, when y=0 so
0=-4(x-1)^2+1 add 4(x-1)^2 to both sides
4(x-1)^2=1 divide both sides by 4
(x-1)^2=1/4 take the square root of both sides
x-1=±√(1/4) which is equal to
x-1=±1/2 add 1 to both sides
x=1±1/2
So x=0.5 and 1.5, thus the x-intercept points are:
(0.5, 0) and (1.5, 0) or if you like fractions:
(1/2, 0) and (3/2, 0) :P
Answer:
63-degrees
Step-by-step explanation:
triangle = 180 degrees
46 + 71 + w = 180
117 + w = 180 *subtract 117 from both sides*
w = 63
Numerical reasoning tests are often done to assess a person's ability to solve or interpret numerical data. A good source to train numerical reasoning is the use of computer education software's that deals with numerical data, the use of textbooks, self test etc.
<h3>What is done in Numerical reasoning tests?</h3>
Here, an individual is often required to analyze numerical data and then they are expected to draw conclusions from the data, which is often presented in tabular or graphical forms.
A person can improve their numerical reasoning by;
- Do make a study schedule and keep to it.
- Do Practice as if you are going for a competition, etc.
A way that a person can improve their speed in an numerical test is to reduce the time it takes a person to take in the information that is shown in the numerical reasoning questions.
