Answer with explanation:</h2>
Let be the population mean.
Null hypothesis :
Alternative hypothesis :
Since the alternative hypothesis is left tailed, so the test is a left-tailed test.
Sample size : n=5 <30 , so we use t-test.
Test statistic:
Critical t-value for t=
Since, the absolute value of t (1.79) is less than the critical t-value , so we fail to reject the null hypothesis.
Hence, we have sufficient evidence to support the company's claim.
Answer:
76
Step-by-step explanation:
Applying the formula to calculate the discriminant Δ=b2−4(a)(c)
Δ=b2-4(a)(c) with : a=3, b=−10, c=2
Δ=(−10)2−4⋅(3)⋅(2) = 100−24 = 76
The discriminant of the polynomial is equal to 76.
The first choice is your answer.
Explanation: SAS congruence includes the 2 sides and the angle between them being congruent.
