Answer:
It's the second one I believe, because it's not a straight line, and nearly all functions have curved lines
Step-by-step explanation:
Area of box : 18*18, which is 324
area of larger triangle : 18*16/2 which is 144
area of larger triangle : 8*16/2 which is 64
add them all to get 532
There is a 2.4% chance of getting two negative tests.
The chance the first test is positive is 0.92, therefore the chance it is negative is 0.08.
The chance the second test is positive is 0.3, therefore the chance is it negative is 0.3.
To find the chance that both tests are negative, we have to multiply them together.
0.08 x 0.3 = 0.024 = 2.4%
Answer:
11 or -16
Step-by-step explanation:
The square of a number increased by 5 times the number is equal to 176.
Let the number be x
Then, x²+5x=176
x²+5x-176=0
We use splitting the middle term method
x²+16x-11x-176=0
x(x+16)-11(x+16)=0
(x-11)(x+16)=0
i.e. either x-11=0 or x+16=0
i.e. either x=11 or x=-16
Hence, the number is either 11 or -16
