Answer:
no solution
Step-by-step explanation:
use grouping method:
f(x) = x^2 - 4x + 2
factor it:
when we try to factor the above equation, we see that there is no ordered pair in which the numbers multiple to -4 and add to 2, so there is no solution
Answer:
What is the probability the mean of his sample will be between $70.00 and $80.00? = 64/64 =1
s1) = 99% =z score = 127/128
s2)64/64 = 1
s3)95% of 64 = 123/128
s4) p) step 3 = 95% of 64 = 60.08 /64 = 60/64 = 93.75%
s5) P)of 2+4 = 283/292 = 96.92%
Answer:
29
Step-by-step explanation:
-9+21= 21
-12+4=-8
21-(-8)=29
2x + 4
Step-by-step explanation:
14/7(x+2)
14 / 7 = 2
SO;
2(x + 2)
Expand the brackets;
2x + 4
Answer:
n=-3.1
Step-by-step explanation:
To solve this, first subtract 3 from both sides of the equation to get 2n=-6.2. Next, divide both sides of the equation by 2 n order to get the final answer of n=-3.1
