You use a modification of the pythagorean theorem to find
pythagoreas c^2=a^2+b^2
the easy way is you use the equation
so input in format (x,y) then
(2,2)
(7,5)
x1=2
y1=2
x2=7
y2=5
the distance is 5 units
Answer:
The pizza was $20
Step-by-step explanation:
$2/10%= $X/100%
Answer:
33 feet.
Step-by-step explanation:
If the ratio of the student to their shadow and flagpole to its shadow are equal, then you can use the proportion
5.5/3 = x/18 and cross multiply to find x.
5.5 × 18 = 99
3 × x = 3x
3x/3 = x, 99/3 = 33.
x = 33.
● Answer:
8.995 cm
● Step-by-step explanation:
P = d + L/2
d = 3.5 cm
L/2 = 2pi×r/2
= pi×d/2
= 3.14×3.5/2
= 5.495 cm
P = 3.5cm + 5.495
= 8.995 cm
Answer: 0.4772
Step-by-step explanation:
Given : The distribution is bell shaped , then the distribution must be normal distribution.
Mean :
Standard deviation :
The formula to calculate the z-score :-
For x = $200
For x = $280
The p-value =
Hence, the proportion of students will spend between $200 and $280 this semester = 0.4772
