Answer:
Null (H0) : Mean chips weight = 1.75 , Alternate (H1) : Mean chips weight < 1.75
Step-by-step explanation:
Null Hypothesis states no deviation from considered population parameter.
Alternate Hypothesis states deviation from considered population parameter. If anticipated deviation may be more or less, its two tail test. If anticipated deviation is only more or less, its left or right tail test .
Null Hypothesis [H0] : Average chips weight = 1.75 ounce
Alternate Hypothesis [H1] : Average chips weight < 1.75 ounce {Left Tail Test}
Answer: He planted 670 acres of corn.
Step-by-step explanation:
Let x be the number of acres of corn and y be the number of acres wheat Farmer planted.
According to the given information, we have the following system of equations:
Divide equation (2) by 135 , we get
Subtract eqn (1) from (3), we get
Put value of x in (1), we get
Hence, he planted 670 acres of corn.
Answer:
A(5 ; 8)
Step-by-step explanation:
y = 5x - 17
y = x + 3
5x - 17 = x + 3
⇔ 5x - x = 3 + 17
⇔ 4x = 20
⇔ x = 20/4
⇔ x = 5
y = 5 + 3 = 8
So (5 ; 8)
