Answer:
the number must be greater than 6.7 Therefore the sum is negative
6.7-7=-0.3
Answer:
there are 165 chocolates in total
Step-by-step explanation:
75/5=15
then you would multiply 15 by 4 and 2 and get 60 and 30
Answer:
X is a discrete random variable.
X can take values from 0 to 12:
Step-by-step explanation:
(a) X = the number of unbroken eggs in a randomly chosen standard egg carton
X is a discrete random variable.
The minimum amount of eggs broken is 0 and the maximum amount of eggs broken is 12 (assuming a dozen egg carton).
Then, X can take values from 0 to 12:
About the probability ditribution nothing can be said, because there is no information about it (it can be a binomial, uniform or non-standard distribution).
Answer:
a, b, and c can be formed a triangle
The area of the triangle is 13385.87 square units.
Step-by-step explanation:
<em>Let us revise an important fact in any triangle</em>
- The sum of the lengths of the two shortest side must be greater than the length of the longest side
The length of the sides are a = 240, b = 132, and c = 330
∵ The two shortest sides are a = 240 and b = 132
∵ a + b = 240 + 132 = 372
∵ The longest side is c = 330
∵ 372 > 330
∴ a + b > c
∴ a, b, and c can be formed a triangle
<em>Let us revise the </em><em>Heron's formula</em><em> of the area of the triangle</em>
- Area = , where a, b,c are the lengths of the sides of the triangle, and
∵
∴
∴
∴
The area of the triangle is 13385.87 square units.
