A. 16 is divisible by 2 but not divisible by 3
B. 23 is not divisible neither by 2 nor 3
C. 27 is not divisible by 2, however it's divisible by 3
D. 36 is divisible both by 2 and 3
So the only number we can focus on is 36:
36 ÷ 2 = 18
36 ÷ 3 = 12
36 ÷ 6 = 6
Answer: D, 36 supports the given conjecture.
<span>Here, we first calculate the value of 't' and then go on calculating the probability that the t-value is more than calculated t-value, given the degree of freedom (d.f. = n-1).
t.calc = (77-76)/(5/sqrt(100)) = 1/(1/2) = 2
P(x > 77) = P(t > 2, d.f. =99) = 0.0241= 2.41%</span>
Answer:
Area = (5 * 6.5)/2 =16.25 sq.yds
Step-by-step explanation:
The area of a triangle is given by half of the product of the base and the height.
Here
base = 5 yd
height = 6.5 yd
Area = (5 * 6.5)/2 =16.25 sq.yds
Answer:
c) 4. i think.
Step-by-step explanation:
Answer:
r=3
Step-by-step explanation:
3(r - 7) = 4(2 - 2r) + 4
Distribute
3r -21 = 8 -8r +4
Combine like terms
3r -21 = 12 -8r
Add 8r to each side
3r +8r-21 = 12 -8r+8r
11r -21 = 12
Add 21 to each side
11r -21+21 =12+21
11r = 33
Divide each side by 11
11r/11 = 33/11
r = 3
