Which values of x are solutions to the inequality?
1 answer:
Answer:
B.
D.
Step-by-step explanation:
Given:
The inequality for 'x' is given as:
The above inequality tells us that, the value of the variable 'x' is less than -200.
-200 is a negative number. So, for a negative number, the larger the value of the number, the smaller the number is.
Example: -2 is less than -1 although 2 has a greater magnitude than 1.
Therefore, the numbers that are less than -200 are -210 and -201.
So, the values of 'x' that satisfy the given inequality are -201 and -210
Thus, the correct options are (B) and (D).

Bart found 20 quadrilaterals in his classroom. He made a Venn diagram using the properties of the quadrilaterals, comparing those with four equal side lengths (E) and those with four right angles (R).
See attachment for the figure.
SOLUTION:
At Venn diagram there are 4 parts (20 pieces):
-> blue colored - quadrilaterals having four equal side lengths (3 pieces)
-> orange colored - quadrilaterals with four right angles (6 pieces)
-> blue and orange colored - quadrilaterals with four right angles and with four equal side lengths (2 pieces)
-> white colored - quadrilaterals without previous two properties (9 pieces).
Considering events:
A -> a randomly chosen quadrilateral has four right angles;
B -> a randomly chosen quadrilateral has four equal side lengths;
By using formula : in order to find probability that a randomly selected quadrilateral with 4 right angles also has four equal side lengths:
