Answer:
Step-by-step explanation:
From the given information:
Assuming we have an integer c to represent the components in the stocks.
Thus, the needed probability can be expressed as:
To break this down, we have:
By solving the equation:
n = 23
Thus, relating to the needed condition; n ≥ 23
The needed number of the components that should be in stock should be at least 23.
Answer:
∠ QPR = 56°
Step-by-step explanation:
Δ RST is isosceles ( 2 congruent sides ) , then base angles are congruent
∠ SRT = 
= 
= 68°
∠ PRQ and ∠ SRT are vertically opposite angles and are congruent , so
∠ PRQ = 68°
Δ PRQ is isosceles ( 2 congruent sides ), then base angles are congruent , so
∠ QPR = 
= 
= 56°
Answer: 30
Step-by-step explanation:
Use long multiplication to evaluate. 44334
You know the factor of 2 will make the result have even numbers. Thus C and D are immediately eliminated. To tell whether the answer is A or B, you only need to find the second number.
.. 2*(1*0 +2*(-1)) = -4
The appropriate selection is ...
B. [14 -4]
