Answer:
No solution
Step-by-step explanation:
x + x + 2 + x + 4 <= 126 (where x is the first of the numbers)
3x <= 120
x <= 40
So the numbers are 40 , 42 and 44.
Answer:
The observed value of the chi-square statistic is 34.71
Step-by-step explanation:
Given the data in the question';
Calculate the observed value of the chi-square statistic
The chi-square statistic will be;
∑
[ ( O
- E
)² / E
]
here O
is observed frequency of
th class
E
is expected frequency of
th class
= 1, 2 which denote the class of food experts who guess correctly and who didn't guess correctly
so
∈
= n × probability of not guessing correctly = 168 × 2/3 = 112
∈1 = n × probability of guessing correctly 168 × 1/3 = 56
so
∑
[ ( O
- E
)² / E
] = [ ( 92 - 56)² / 56 ] + [ ( 76 - 112)² / 112 ]
= 1296/56 + 1296/112
= 23.14 + 11.57
= 34.71
Therefore, the observed value of the chi-square statistic is 34.71
Answer:
Where do you live I am gonna steal-I mean pet him ;}
Step-by-step explanation:
Point-slope form: y - y₁ = m(x - x₁)
[m is the slope, x₁ and y₁ ---> (x₁, y₁) is the point]
Since you know:
m = 5
(2, 6) = (x₁, y₁) Substitute/plug in the values into the equation
y - y₁ = m(x - x₁)
y - 6 = 5(x - 2) The 1st option is your answer
