Bust out the calculators, it's long numbers math time!
What you'll need to do is put into your calculator is this exactly, parentheses and all:
(6×10^6)/(2×10^4)
What's happening here is the calculator will use order of operations to, first, solve what's in the parentheses. Then, the calculator will divide those enormous numbers because the question asks how many 'times' larger, which refers to division, and you'll get your answer. Sorry I couldn't show my work on this one. With numbers as large as this, it's better to enter them into your calculator.
Answer:
1) confidence level
3) 0.75 + - 0.25
4) The candy manufacturer’s claim is likely true, as evidenced by a z-score that is less 1.645.
7) ![0.87+-1.645\sqrt{\frac{0.87(1-0.87)}{1026} }](https://tex.z-dn.net/?f=0.87%2B-1.645%5Csqrt%7B%5Cfrac%7B0.87%281-0.87%29%7D%7B1026%7D%20%7D)
9) (0.33,0.36)
Step-by-step explanation:
Answer:
The component on the left of original one would be
30 x cos45 =30 x sqrt2/2 =~21.21
The component on the right of original one would also be
30 x cos45 =30 x sqrt2/2 =~21.21
Answer:
For a 45 45 90 triangle
leg = hypotenuse / (square root of 2)
leg = 128 / 1.4142135624
leg = 90.5096679902 cm
Step-by-step explanation:
105 ÷ (−15) = -7
15 goes into 105 seven times and then you carry the minus over.
