Answer:
The mean launch temperature for flights with O-ring damage is significantly lesser than Flights with No O-ring
Step-by-step explanation:
Let
Null hypothesis : H0 : μ1 ≥ μ2
Alternate hypothesis : Ha : μ1 < μ2
next calculate the test statistic
t = -2.312
calculate the P-value
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
Attached below is the detailed solution
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!
First take out the parenthese
then you can subtract 2i from -1i to get i
then add 4 to 3
hence the answer, 7/i
