Answer:
2 goals
Step-by-step explanation:
After 5 games the team scored 1.8*5=91.8∗5=9 goals.
After 6 games the team scored 9+3=129+3=12 goals.
The mean after 6 games is \frac{12}{6}=2
6
12
=2 goals.
Actually Welcome to the Concept of the Statistics of a Categorised data.
We know that medium is the middle most point of any observation table or a Histogram displayed,
Hence we can clearly see here that, observation - 4 on the x-axis is the middle most entry of the Histogram, around which all other entries are equal.
===> Hence, option A.) 4 is correct answer.
Answer:
50 A and 50 B
Step-by-step explanation:
A》20
B》10
A + B》100 (for pants)
A + 3B》200 (for shirts)
A = 20
A + 3B = 200
3B = 180
B = 60
(20,60)
B = 10
A + B = 100
A = 90
(90,10)
A + B = 100
A = 100 - B
A + 3B = 200
100 - B + 3B = 200
2B = 100
B = 50
A = 100 - 50 = 50
(50,50)
Revenue:
30A + 50B
(20,10): 30(20) + 50(20)
= 1,100
(20, 60): 30(20) + 50(60)
= 3,600
(90,10): 30(90) + 50(10)
= 3,200
(50,50): 30(50) + 50(50)
= 4,000
Answer:
x = 10 and y = 10√2.
Step-by-step explanation:
The right triangle has another one angle of 45°.
Therefore, the angles of the right triangle are 90°-45°-45°.
Hence, it is an isosceles right triangle.
Then, the legs of the right angle are equal to be 10.
So, x = 10
Now, the length of the hypotenuse is given by Pythagoras Theorem i.e.
(Hypotenuse)² = 10² + 10²
⇒ y² = 200
⇒ y = 10√2
Therefore, x = 10 and y = 10√2. (Answer)
