Answer:
384 cubic meters
Step-by-step explanation:
Think of it as two rectangles on top of each other and then add the two volumes.
Volume is l*w*h
So for the bottom rectangle: (8) (12) (2) = 192 cubic meters
And for the top rectangle: (4)(6)(8) = 192 cubic meters
It is important to remember that for the top box you have to subtract the height of the bottom box which is why I used 4 for the height instead of 6.
Then you add them together.
192+192 = 384 cubic meters
If a fair coin is tossed 8 times, what is the probability, to the nearest thousandth, of
getting exactly 7 tails?
The probability of getting exactly 7 tails is 1/32.
How to find probability using binomial distribution?The binomial distribution is based on the binomial theorem which can be written as (a + b)ⁿ = ⁿC₀aⁿb⁰ + ⁿC₁aⁿ⁻¹b¹ + ⁿC₂aⁿ⁻²b²+ ....+ ⁿCₙa₀bⁿ.
In order to use in the probability, there should be events independent of each other and the sum of there probabilities is 1.
The number of times of toss of a fair coin is given as 8.
The probability of getting head is 1/2.
And, the probability of getting tail is 1/2.
The given problem can be solved using the expression of binomial distribution as ⁿCₓpˣqⁿ⁻ˣ, where p and q are the probability of success and failure respectively, n is the total number of trials and x is the favorable number of trials.
In order to find the probability of getting tail 7 times out of 8, the binomial distribution can be used as,
P(exact 7 tails) = ⁸C₇(1/2)⁷(1/2)¹
= 8 × 1/128 × 1/2
= 1/32
Hence, the probability of getting exactly 7 tails is 1/32.

The number of miles that he walked will be 6 miles.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The perimeter of the triangle is determined by adding together all of its sides.
The perimeter of her walk is calculated as,
P = 2.4 + 2.1 + 1.5
P = 6 miles

When a fair 6-sided dice is rolled 10 times, the resulting face values are as
follows: 1, 2, 6, 5, 5, 6, 3, 4, 5, 1. After conducting the experiment, the researcher
claims that P(5) = .30. This is an example of ______
probability.
Answer:
This is an example of independent probability.
Step-by-step explanation:
Independent events are not affected by previous events, just like the outcome of rolling a dice is not effected by the previous outcome. (The dice has no memory of any kind, what so ever!).
When two events are said to be independent of each other, meaning the probability that one event occurs in no way affects the probability of the other event occurring. Another example of an independent event is when you flip a coin. (The coin has no memory of any kind, what so ever!).
Multiplication Rule: When two events, A and B, are independent, the probability of both occurring is:
P(A and B) = P(A) · P(B)
The dice was cast 10 times. In three occasions a 5 came out, and in 7 occasions another outcome occurred. The probability of the outcome of exactly 3 times a 5 in 10 casts, can be calculated as:
P(5) =(1 / 6)^3 + (5 / 6)^7
P(5) = 0.28
P(5) = .3

Answer:
y= 200/6x + 100
Step-by-step explanation:
Process of elimination it can't be y= 2/3x + 100 or y = 2/3x because then for x = 12 y would equal 108, but it was closer to 200. That means it had to be one of the other two, the one without the +100 would also end up being too little.

The regional manager of a chain of department stores created the following stem and leaf plot showing the number of pairs of glasses at each of the stores how many department stores have exactly 37 pairs of glasses
Answer:
The stem and leaf plot is not shown, so I will answer the question in a general way.
Suppose you have the following stem and leaf plot
I 2 I 0 5 8
I 3 I 4 4 7 8
I 4 I 0
Then, the data is: 20, 25, 28, 34, 34, 37, 38, 40. In consequence, one department stores has exactly 37 pairs of glasses. But if your stem and leaf plot is:
I 2 I 0 5 8
I 3 I 7 7 7 8
I 4 I 0
then, three department stores have 37 pairs of glasses, and none of them have 34 pairs of glasses.
