Answer:
11/40 + 1/4 + 1/20
Step-by-step explanation:
Draw a Venn diagram: (as shown)
Consumer Ed. : 22-4=18
French : 20-4=16
Neither : 80-18-16-4=42
Using probability notation where P(A) means probability of event A occurring.
P(Consumer Ed.) = 22/80
P(French) = 20/80
P(Both) = 4/80
<em>'or ' </em>in the question means you add.
=> 22/80 + 20/80 + 4/80
=> 11/40 + 1/4 + 1/20
Answer:
628.32
Calculate by using the equation πr² where r is the radius of the circle
1 day = d
0 + 3d = 4 + 2d
3d = 4 + 2d
d = 4
It'll take 4 days
Hope this helps ^-^
Mean of all scores means add them all up then divide by number of scores (5)
so
the mean has to be at least 95 aka, greater than or equal to 95
so
represent the last score with x
mean is the sum of all scores
multiply both sides by 5
minus 378 from both sides
he has to get at least 97 on the last test to get the highest score
good luck, marvin
Answer:
It is not a right triangle
This is a scalene triangle
Step-by-step explanation:
A right triangle is a triangle in which one of the angles is a 90∘ angle. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.
This cannot be obtuse b/c it does not add up to 180.
A triangle is scalene if all of its three sides are different (in which case, the three angles are also different).
