Step-by-step explanation:
i just did it on Edmentum 8th grade math.
Answer:
The probability that she gets all 7 questions correct is 0.0078.
Step-by-step explanation:
We are given that Karri takes a 7 question true-false test and guess on every question.
The above situation can be represented through binomial distribution;
where, n = number of samples (trials) taken = 7 question
r = number of success = all 7 questions correct
p = probability of success which in our question is probability that
question is correct, i.e. p = 50%
Let X = <u><em>Number of question that are correct</em></u>
So, X ~ Binom(n = 7, p = 0.50)
Now, the probability that she gets all 7 questions correct is given by = P(X = 7)
P(X = 7) = 
= 
= <u>0.0078</u>
Volume = length * width * height
Each asterisk * refers to the multiplication symbol
The volume of the cube is equal to the length times width times height
---------------------
Example:
Consider a cube that has length, width and height each equal to 4 cm
Volume = length * width * height
Volume = (4 cm) * (4 cm) * (4 cm)
Volume = (4*4*4) cubic cm
Volume = 64 cubic cm
----------------------
Another example:
We have a rectangular prism that has the following dimensions
length = 4 ft
width = 3 ft
height = 5 ft
Computing the volume gets us:
Volume = length * width * height
Volume = (4 ft) * (3 ft) * (5 ft)
Volume = (4*3*5) cubic ft
Volume = 60 cubic ft
The area of a rectangle can be calculated by the product of its length and the width. Here we are given the area and the length so we can simply calculate for width. The perimeter is the sum of all the side lengths of the shape. We calculate as follows:
Area = lxw
1/6 = 1.5w
w = 1/9
Perimeter = 2l + 2w
Perimeter = 5/9
Hope this answers the question. Have a nice day.
