Step-by-step explanation:
Given that Lincoln has pennies and nickles and that his total worth is $0,
we can express his total using the inequality:
Where the sum of n and p is his total
Hence, Lincoln's situation is expressed as p+n=0
Answer:
4
Step-by-step explanation:
Absolute value is just the number without and negative signs, for example, -5 would have an absolute value of 5
1 ft= 12 inches
12*5=60 inches
Is 64 inches greater than, less than or equal to 60 inches?
64 inches is greater than 60 inches
So, 64 inches is greater than 5 ft
Answer:
C. We want to determine if there is significant evidence that the mean strength of welds exceeds 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is satisfied.
Step-by-step explanation:
Given
Required
State why it is preferred to
From the question, we understand that the initial test is the force required to break the weld.
This represents the null hypothesis
Because the required force can not be less than the strength of the weld (it must match the force keeping the weld), the null hypothesis is represented as:
Reading the question further;
The specification requires that the mean strength should exceed 100
In inequalities, exceeds means greater than, and it is represented with >
So, the null hypothesis is rightly represented as:
Hence: (c) is true
