Answer:
d. y = 3x + 5
Step-by-step explanation:
plug x = 2 in the equation y = 3x +5
y = 3*2 + 5
y = 11
so x = 2, y = 11
we know d is the correct statement
Answer:
Step-by-step explanation:
The equation to solve is:
To get rid of the "square", we need to take square root of both sides:
Then we use algebra to find the value(s) of x. Remember, when we take square root, we have to add up a "+-" (on the right side). Shown below:
So these are 2 answers for x.
Answer: Hi, the answer is the margin of error would be 19 for 2 s.d. or 18.6 for 1.96 s.d
Step-by-step explanation: The margin of error needs to be defined, but if one uses 1.96 (95% by empiric rule for normal distributions), it is 3.72. For 2 s.d, it is 3.61
The margin of error would be 19 for 2 s.d. or 18.6 for 1.96 s.d The margin of error is +/-19, for example, the interval within the margin of error would be (186, 224).
Answer:
4.0
Step-by-step explanation:
A=p(1+i/m)^mn
A=26,000÷(1+0.06÷2)^(2×7)
