Answer:
42 degrees
Step-by-step explanation:
it’s the same as the other one
Answer:
All triangles add up to 180 degrees
right angles are 90 degrees
we add 41 and 90 to find how many degrees are already there
41 + 90 = 131
we need 180 degrees so we see how many degrees are left
180 - 131 = 49
49 degrees are left so 49 is the answer because 49 finishes the triangle
Hope this helps
Step-by-step explanation:
Answer:
(a) 99%
(b) 50%
Step-by-step explanation:
(a) All factorials after 1! have 2 as a factor, so are even. Thus 99 of the 100 factorials are even, for a probability of 99%.
__
(b) The first two sums are odd; the next two sums are even. The pattern repeats every four sums. There are 25 repeats of that pattern in 100 sums, so 2/4 = 50% of sums are even.
Answer:
x = 6
Step-by-step explanation:
x + 7x = 48
8x = 48
Answer:
The domain is [0, ∞)
Step-by-step explanation:
y = √x
The domain is all values of x that make the expression defined.
so the function is defined for all positive numbers.
So domain is [0, ∞)
