Step-by-step explanation:
Step-by-step explanation:
The marginal totals are the sum of each row and column.
For example, the total number of sophomores is 120 + 302 = 422.
See picture of table with marginal totals filled in.
Answer: x=-5 or x=2
Step-by-step explanation:
x^2+3x-10=0
x^2+5x-2x-10=0
x(x+5)-2(x+5)=0
(x+5)(x-2)=0
x+5=0 or x-2=0
x=-5 or x=2
Answer:
0
Step-by-step explanation:
H0 : μ = 840
H1 : μ < 840
Sample size, n = 49
Standard deviation, s = 14
Test statistic = (xbar - μ) ÷ (s/√(n))
Test statistic = (830 - 840) ÷ (14/7)
Test statistic = - 10 / 2
Test statistic = - 5
The Pvalue ;
Pvalue = P(Z < - 5) = 0 (Z probability calculator)
The Pvalue = 0
