1. first we find how many defective capacitors are there out of 133, 450:
in 34 capacitors --------- 1 defective
in 133,450 capacitors --------- x defective
so
is the expected number of defective capacitors.
2.
So there are in total 133,450-3925=129,525 working capacitors.
3.
To assemble 1,987 smartphones the corporation needs 1,987*66= 131,142 working capacitors.
4.
The number of required capacitors is larger than the number of the available ones, so 133,450 capacitors are not enough.
Answer: No
Answer:
See below.
Step-by-step explanation:
sin(71) = x/23
x = sin(71) * 23
x = 21.75
Answer:
The answer is c. f(n)=4n+1
Step-by-step explanation:
In the function of the answers, n is the input and f(n) is the output. So the ordered pairs needs to be at the form (n,f(n))
Additionally, in the ordered pairs given in the question, the first term is the input and the second term is the output. For example in the ordered pair (1,5), 1 is the input and 5 is the output.
So, if we replace n by 1, f(n) needs to be 5. This condition is only satisfied on option c. That's is also prove for every ordered pair as:
For (1,5)
if n=1 then:
f(n)=(4*1)+1=5
For (2,9)
if n=2 then:
f(n)=(4*2)+1=9
For (3,13)
if n=3 then:
f(n)=(4*3)+1=13
For (4,17)
if n=4 then:
f(n)=(4*4)+1=17
Finally, the functions that best represents the rule that the calculator uses to display the outputs is f(n)=4n+1
Answer:
50
Or D (if D is 50)
Step-by-step explanation:
4.5x+396=621
Subtract 396 from both sides. (Subtraction Property of Equality)
4.5x=225
Divide both sides by 4.5 to get x by itself. (Division Property of Equality)
x=50
-7, 2/3, √81, 0.25 are rationals .
