arlik [135]

Answer:

The mean launch temperature for flights with O-ring damage is significantly lesser than Flights with No O-ring

Null hypothesis : H0 : μ1 ≥ μ2

p-value = T.DIST ( t ,df )  (  excel function )

            = 0.0270

Given that P-value ( 0.020 ) < level of significance ( 0.05 ) we will not fail to reject the null hypothesis

Which best describes the solution to 4 minus 7?
Basile [38]

Answer:

The answer would be "because 4 + (negative 7) is an equivalent expression, the answer is –3".

Step-by-step explanation:

First of all, determine if the answer is going to be positive or negative by seeing the sign of the greater number (that would be 7). So, the answer would be negative. Then do the expression using absolute values; 7-4=3. Now, just add the negative sign before 3 and that's it. You did it! Please rank Brainliest if this helps. Thank you!
