Answer:
it is 1/4
Step-by-step explanation:
20/60=10/30=1/3
Step-by-step explanation:
sin∅ = opposite / hypotenuse
Answer:
sin(K) = 48/50
sin(P) = 14/50
Answer:
Option B
Step-by-step explanation:
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
By substituting the values in the given expression,
7² = x² + 2²
49 = x² + 4
x² = 49 - 4
x² = 45
x = √45
x = 3√5
x = 6.7 ft
Option B will be the correct option.
Answer:
B
Step-by-step explanation:
the mean is calculated as
mean = 
this year's mean = 
= 
= 4.1
last year's mean = 
= 
= 3.1
difference = 4.1 - 3.1 = 1
54 55 59 61 61 62 68 70 72
First put your numbers in order from least to greatest. This shows your minimum is 54 and maximum is 72.
In the middle of the data set is 61.
54 55 59 61. 61. 62 68 70 72
To find the first qaurtile only use the numbers before rhe median (54 55 59 61) and find the median of that. Since 55 and 59 are both in the middle add them both and divide by two to find the middle lf those two numbers. You should get 57. So 57 is the first quartile.
Do the same steps with the numbers after the meadian for your third quartile. You should get 69 as your answer for the third quartile.
