The way I figured this one out was saying that if it takes 2lbs to stretch it to 12 inches and 5lbs to stretch to 18 inches that means that 3 additional pounds = 6 inches. Therefore, each additional pound is 2 inches. We know already that with 2 lbs it was 12 inches in length and we can also say that 2 lbs = 4 inches. So subtract 4 from 12 and you end up with the answer of 8 inches.
Answer:
b. 0.0228
Step-by-step explanation:
We are given that
n=40
Mean,
Standard deviation, 
g
We have to find the probability hat the mean weight for a sample of 40 summer squash exceeds 405.5 grams.
Hence, option b is correct.
Answer: C is approximately 9.42.
Step-by-step explanation: the radius is 1.5 and the C formula is 2 x pi x r = 2 (3.14)(1.5)
It's the one in the top right corner. Since the inequality says 'greater than or equal to' the line has to be bold and the shaded area has to be above the line. Hope this helped!
For factorisation it is necessary that you multiply the last and first values
Here we can see : we require 27a^2
SO if we multiply the answer should be 27 and if we add the answer should be 28 ....here goes !!
a^2 + 28a + 27
a^2 + 27a + 1a + 27
Here we can see : I we multiply 27 and 1 the answer will be 27a^2 but if we add 27 and 1 as shown then answer will be 28a:
a ( a + 27 ) + 1 ( a + 27 )
( a + 1 ) × (a + 27 )
HOPE IT HELPED!!
