Answer:
yes
Step-by-step explanation:
negative numbers work backwards, in this case 8 is smaller then 5 as its farther in the numberline (if you were to draw one)
2 #'s whose sum is 51: x + y = 51
2 #'s whose difference is 13: x - y = 13
add the 2 equations: 2x = 64 ⇒ x = 32
using either equation find y: 32 + y = 51 ⇒ y = 19
Answer the 2 #'s are 32 and 19
With negative exponents you make it a fraction.
For example with your equation it would be
1/2^7<2
So basically you just flip the fraction to cancel out the negative then you can continue to solve.
Answer:
normalcdf(-1^99, 25.1, 25, 1.2) = .226627 or 22.66%
Answer: c
Step-by-step explanation:
5.00 can be divided by 2 and this the out come 2.5(y)
same goes with 12.50 but by 5 and equal 2.5 (x)
if you have trouble theirs a calculator called Desmos.
