8^1/3
8 is 2^3 so 8^1/3 = 2
The other expresssions don't give whole numbers.
Answer:
a) The level of significance is large because here z is not appropriate.
b) The true critical value is larger than z because the level of significance is large.
Step-by-step explanation:
a) Based on the question under consideration, the true level of significance is larger than .05 level of significance is large, the reason being that z is not appropriate in this case.
b) The true critical value is larger than that of the critical z, this is because the level of significance is large.
t* in P(T > t*) = 0.975 is more than z* = 1.96 in P(z> z*) =0.975
Answer:
-5
Step-by-step explanation:
The initial value would be the value when x=0. Substituting 0 for x,
y = -2(0)-5
y = 0 - 5
y = -5
Answer:(-2, 2)
Step-by-step explanation:
7q² - 28 = 0
Add 28 to bothside
7q² - 28 + 28 = 0+ 28
7q² = 28
Divide bothside by 7
7q² / 7 = 28/7
q² = 4
Take the square root of bothside
√q² = ±√4
q = ± 2
q = -2 or q =2
q = (-2, 2)
Answer:
Step-by-step explanation:
Initial class size = 30 students
<u>Class size now is 40% larger:</u>
- 30 + 40% =
- 30 + 30*40/100 =
- 30 + 12 =
- 42
