1 inch = 2.54 cm
100 cm * (1 inch)/(2.54 cm) = 39.37 inches
Penny is taller
Answer:
201
Step-by-step explanation:
What you do is you first find the formula which is 3.14(r^2)(h/3)
So it will be 3,14(4^2)(12/3). why it is 4 is because a radius is half the length of the circle and they gave you the length of the full circle so you half it.
Your answer is 200.96 but to the nearest whole number is 201.
Yes I think. I pretty sure yes
Answer:
The expected number of graphing calculators that malfunctions within 3 months and need to be replaced is 915,000.
Step-by-step explanation:
Let <em>X</em> represents the number of graphing calculator that starts malfunctioning within 36 months of the purchase and needs to be replaced by a new one.
It is provided that <em>X</em> follows a normal distribution with a mean of 54 months and a standard deviation of 8 months.
Also, using the normal model it was determined that 1.22% of graphing calculator manufactured by Texas Instruments malfunctions and needs replacement.
That is,
P (<em>X</em>) = 0.0122
Texas Instruments has sold 75 million graphing calculators world- wide.
Compute the expected number of graphing calculators that malfunctions within 3 months and need to be replaced as follows:
E (<em>X</em>) = n × P (<em>X</em>)
= 75 × 10⁶ × 0.0122
= 915000
Thus, the expected number of graphing calculators that malfunctions within 3 months and need to be replaced is 915,000.
Answer:
The answer is y = -1/3x - 1
Step-by-step explanation:
In order to find this we first must note that parallel lines have the same slope. Therefore, since the slope in the original line is -1/3, then we know the slope in our line will be the same. Now we can use point slope form with that slope and the given point to find the equation by solving for y.
y - y1 = m(x - x1)
y + 3 = -1/3(x - 6)
y + 3 = -1/3x + 2
y = -1/3x - 1
