Step-by-step explanation:
The statement in the above question is True.
Sum of three prime numbers (other than two) is always odd.
Going by Christian Goldbach number theory ,
- Goldbach stated that every odd whole number greater than 5 can be written as sum of three prime numbers .
Lets take an example,
- 3 + 3 + 5 = 11
- 3 + 5 + 5 = 13
- 5 + 5 + 7 = 17
Later on in 2013 the Mathematician <u>Harald Helfgott</u> proved this theory true for all odd numbers greater than five.
Answer:
100 times
Step-by-step explanation:
multiples of 3 on a number cube are 3 and 6
probability of rolling a '3' or '6' is 1/6 + 1/6 = 2/6 or 1/3
1/3 x 300 = 100
I think it's along the y-axis.....
18). 16:80 is the ratio but in simplest form is; 5:0
19). 36:54 is the ratio but in simplest form is; 2:3
20). 12:24 is the ratio but in simplest form is; 1:2
hope that helps:D
Answer:
The truck travel must to have a constant speed of ![22.06\ ft/sec](https://tex.z-dn.net/?f=22.06%5C%20ft%2Fsec)
Step-by-step explanation:
we have
![d=1.3t^{2}+t+2](https://tex.z-dn.net/?f=d%3D1.3t%5E%7B2%7D%2Bt%2B2)
where
d expresses a car's distance in feet
t is the number of seconds
<em>Find the distance d for t=8 sec</em>
![d=1.3(8)^{2}+8+2=93.2\ ft](https://tex.z-dn.net/?f=d%3D1.3%288%29%5E%7B2%7D%2B8%2B2%3D93.2%5C%20ft)
<em>Find the distance d for t=8.2 sec</em>
![d=1.3(8.2)^{2}+8.2+2=97.612\ ft](https://tex.z-dn.net/?f=d%3D1.3%288.2%29%5E%7B2%7D%2B8.2%2B2%3D97.612%5C%20ft)
The total distance in this interval of 0.2 sec is
![97.612-93.2=4.412\ ft](https://tex.z-dn.net/?f=97.612-93.2%3D4.412%5C%20ft)
<em>Find the speed of the car</em>
Divide the total distance by the time
![4.412/0.2=22.06\ ft/sec](https://tex.z-dn.net/?f=4.412%2F0.2%3D22.06%5C%20ft%2Fsec)
therefore
The truck travel must to have a constant speed of ![22.06\ ft/sec](https://tex.z-dn.net/?f=22.06%5C%20ft%2Fsec)
