Answer:
8+3(2)
Step-by-step explanation:
8 more than indicates addition, so that makes the first part of the expression 8+.
The product of 3 and 2 indicates multiplication, since product means the result of multiplication. That finishes the expression with 3(2).
In conclusion, a numerical expression that matches the states phrase is 8+3(2). You can also do 8+3×2 too, as they equal the same thing.
Answer:
How many storage tanks are needed to contain 60,000 cubic meters of liquid?
Step-by-step explanation:
Answer:
In this case we use the Poisson distribution because we are talking about the occurrence of an event (number of tracks) over a specified interval (in this case an area interval).
The probability of the event occurring x times over an interval is:
P(x) = nˣ × e⁻ⁿ ÷ x!
where n is the mean.
a) P(7) = 6⁷ × e⁻⁶ ÷ 7! = 0.1376
b) P(x ≥ 3) = 1 - P(x < 3) = 1 - P(2) - P(1) - P(0)
P(2) = 6² × e⁻⁶ ÷ 2! = 0.0446
P(1) = 6¹ × e⁻⁶ ÷ 1! = 0.0149
P(0) = 6⁰ × e⁻⁶ ÷ 0! = 0.0025
P(x ≥ 3) = 0.9380
c) P(2 < x < 7) = P(3) + P(4) + P(5) + P(6) = 0.0892 + 0.1339 + 0.1606 + 0.1606 = 0.5443
d) The mean is going to be 6.
e) The standard deviation is √n = √6 = 2.4
Answer:
48
Step-by-step explanation:
the top shape is 6 by 6, which is 36
the bottom shape is 3 by 4, which is 12.
if you add the two areas, 12+36, you get 48. so the area of the entire shape is 48mi
Answer:
The age of pluto is:
5,560,000,000 years old = 5.56 × 10⁹ years old
x = 5.56
y = power of 9
Step-by-step explanation:
Pluto is 5,560,000,000 years old. Estimate the age of Pluto by writing it in the form of x×10y years, where x and y are single-digit numbers.
We write this in standard form or scientific notation.
5,560,000,000 years old = 5.56 × 10⁹ years old
x = 5.56
y = power of 9
