Like terms are terms with the same variable and exponent.( they can have different coefficient)
4c and 7c are like terms since they have same variable ‘c’
2 and -5 are like terms because both of them have no variable
Answer:
Step-by-step explanation:
P(-a<z<a)=0.60, from the symmetry of normal distribution, P(z<a) = 0.60+ (1-0.60)/2 =
0.60+0.4/2
0.60+0.2
= 0.8
Considering the standard normal distribution table, we have a = 0.80, thus
z =(x-m)/std = 0.80
the maximum x = m + 0.80×std =
Where m = 246300
Std = 15000
246300+0.80×15000
= 246300+12000
= 258300
For the minimum x
x = m - 0.80×std
x = 246300-0.80×15000
246300-12000
= 234300
Answer:
72w+36
Step-by-step explanation:
Answer:
B. 11+x
Explanation:
Its the answer because in B it's the same as x+11 but in an opposite way.
11+x
x+11
