ANSWER
(-2,4] and [7,∞).
EXPLANATION
The domain refers to the interval on which the function is defined.
In the case of the graph, the domain refers to all the x-values for which the graph exists.
The graph is defined for x-values greater than 2 but less than or equal to 4 and
x-values greater than or equal to 7.
In interval notation, we have:
(-2,4] and [7,∞).
The second choice is correct:
Answer: 124
Explanation: 4[3(10-7)+(11•2)]
Parentheses - 4[3(3)+(22)]
Parentheses - 4(9+22)
Parentheses - 4(31)
Multiplication - 124
Answer:mean= 2905.83, median=3398, mode=5456
Step-by-step explanation:
The mean:
Mean=summation of six machine produced/ n
Mean=(2567+5456+3769+2245+3398)/6
Mean=17435/6
Mean=2905.8333333
b. The median
Firstly we have to rearranged the machine product in order:
2245, 2567, 3398, 3769, 5456
So 3398 is at the middle, so median is 3398
c. The mode
The machine produces the highest number (frequency) is mode. So the mode is 5456
Answer:
(5y-2)x(2x+5)
Step by step explanation:
10xy-4x+25y-10
Factor out 2x from the expression
2x*(5y-2)+25y-10
Factor our 5 from the expression
2x*(5y-2)+5(5y-2)
Factor out 5y-2 from the expression
(5y-2)x(2x+5)
Joe is making $485 payments monthly, but the amount gets interest on a yearly basis, not monthly, so the amount that yields interest is 485*12
also, keep in mind, we're assuming is compound interest, as opposed to simple interest
