Answer:
The normal distribution is symmetric about its mean.
So Answer C) must be true.
You go from left to right and tell what each numeral represents write it as a factor of 10.
The 1 is "one ten" because it is in the 10's place
We can write that as 1 x 10¹
The 2 "two ones" which can be written as 2 x 10⁰ (anything to the zero power is 1)
Negative powers of 10 will help us with the decimals
The 5 is "five tenths" or 5 x 10⁻¹
The 7 is "five hundredths" or 7 x 10⁻²
Finally the 6 is "6 thousandths" or 6 x 10⁻³
Final answer in expanded form is:
1 x 10¹ + 2 x 10° + 5 x 10⁻¹ + 7 x 10 ⁻² + 6 x 10⁻³
The answer is B. The slope is -4 and the y-intercept is 1, so the equation is
<em>y=-4x+1</em>. That matches with option <em>B.
</em>
I hope this helped. You can mark me brainliest if you think I deserve it (:
Answer:
x ≈ 17.32, y = 20
Step-by-step explanation:
sin (30°) = 10/y
=> y = 10/sin (30°)
=> y = 20
x = 
=> x ≈ 17.32
