The box plot shows the number of cousins students in Mr. Myers class have. Which statement about the data must be true
2 answers:
Answer:
We choose C
The spread from the lower quartile to the median is greater than the spread from the median to the upper quartile.
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one.
Please have a look at the attached photo
My answer:
Given the information in the photo, we can know that:
Median: 7
- Upper quartile: 9
- Lower quartile: 4
- Interquartile range: 9 - 4 = 5
- Lower quartile to median: 7 - 4 = 3
- Upper quartile to median: 9 - 7 = 2
Let analyse 4 answers:
A. Wrong, Lower quartile to median is more than Uper quartile to median
B. Wrong
C. True
D. Wrong

Answer:
Step-by-step explanation:
Given:
°
From the triangle, using the theorem that center angle by an arc is twice the angle it subtend at the circumference.
Also, the diameter of the circle is BD. As per the theorem that says that angle subtended by the diameter at the circumference is always 90°,
From the Δ BCD, which is a right angled triangle,
Now, using the theorem that angle between the tangent and a chord is equal to the angle subtended by the same chord at the circumference.
Here, chords CD and BC subtend angles 40 and 50 at the circumference as shown in the diagram by angles and EF is a tangent to the circle at point C.
Therefore,
Again, using the same theorem as above,
Hence, all the angles are as follows:
Answer:
The answer is 23 years.
Step-by-step explanation:
We will use the formula :
Here P = 220
r = 3%
A = 400
Putting these values in the formula we get,
Taking log on both sides,
ln(1.03)t=ln 2
t=23.44 or rounding to nearest, t=23 years
The graph of the function can be shown as below.
