I’m honestly not sure but it could be right
The answer I got is &6.60

Answer:</h2>
Option: D is the correct answer.
D. 0.45
<h2>
Step-by-step explanation:</h2>
The results of the experiment are given as follows:
Coin Experiment Side of Coin Number of Tosses
Heads 18
Tails 22
This means that total 40 experiments were performed.
( Since 18+22=40)
Also, the number of times head turn up=18
Hence, the experimental probability of getting heads is:
Ratio of number of times head turn up to the total number of experiments performed.
Hence,
Hence, the experimental probability of getting head is:
0.45
Answer:
See below
Step-by-step explanation:
So, on the complex plane, we see that
Therefore,
Since we added the complex numbers, we can see that the real part of is 8 and the imaginary part of is -2. Remember that complex numbers are written in the form of , so either the real or imaginary part can both be negative.
Answer:
The lateral height of the square pyramid is
Step-by-step explanation:
step 1
Find the surface area of the cube
The surface area of the cube is equal to
where
b is the length side of the cube
w have
substitute
step 2
Find the lateral height of the square pyramid
we know that
the surface area of the square pyramid is equal to
where
B is the area of the base
b is the base of the lateral triangle (base of the square)
h is the lateral height of the square pyramid
-----> is the same surface that the cube
substitute the values and solve for h
(3/4)+(7/8)
(6/8)+(7/8)
13/8
1((13-8)/8)
1 (5/8)
The answer is a. 1 5/8 hr
