Odd numbers are of the from a(n)=a+d(n-1) where a=1 and d=2 so
a(n)=1+2(n-1)=2n-1 and we need the number of odds in the range 1 to 38
2n-1≤38
2n≤39
n≤19.5, so there are 19 odd numbers in [1,38]
And since Julie bet on two even numbers as well, the probability of getting an odd number or the two evens she picked is:
(19+2)/38
21/38
Answer:
B. 2.75 mph
Step-by-step explanation:
If it took him 2 hours to walk 5.5 miles, 5.5 ÷ 2 = 2.75, which is what he walked in a single hour, meaning he was walking 2.75 mph
It is easy to make a decimal by dividing the numerator by the denominator.
6/29=0.2068965517241379.
We can round it to the tenths and the final answer would be 0.2.
Answer:
height is 6.8m
Step-by-step explanation:
SO both area is same
For trapezoid area is
(10+7) * 4 * 1/2 = 34
And for triangle area equation is
10 * h * 1/2 = 34
here find h
h= 34 *2 * 1/10
h=6.8
