Put days on x axis and number of ammusent parks on y axis. then make your dot plot
Answer:
BD = 14
Step-by-step explanation:
Using Pythagoras' identity on Δ's ADC and ABC
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, thus
BC² + 12² = 15²
BC² + 144 = 225 ( subtract 144 from both sides )
BC² = 81 ( take the square root of both sides )
BC = = 9
and
DC² + 12² = 13²
DC² + 144 = 169 ( subtract 144 from both sides )
DC² = 25 ( take the square root of both sides )
DC = = 5
Hence
BD = BC + DC = 9 + 5 = 14
The horizontal and vertical vector components of the velocity vector V, namely Vx and Vy are; 505.32 ft/s and 721.57 ft/s respectively
<h3>Horizontal and Vertical components of vectors</h3>
For ease of computation since vectors have magnitude and direction; they are resolved into horizontal and vertical components.
By convention, the horizontal, Vx and vertical components, Vy are as follows;
- Vx = V cos π
- Vy = V sin π
where π = angle of inclination to the horizontal.
Hence,
- Vx = 881 × cos55° = 505.32 ft/s
- Vy = 881 × sin55° = 721.57 ft/s

Answer:
(Correct to 4 decimal places)
Step-by-step explanation:
The probability of a continuous normal variable X found in a particular interval [a, b] is the area under the curve bounded by x=a and x=b and is given by:
where
Using a calculator,
2.6 because the next number is 1 which is less than 5 so it is rounded down, if it was 2.65 or higher you would round up to 2.7
