Answer:
c is -30
Step-by-step explanation:
I. 1/a - 1/b - 1/d = 1/c
II. 1/2 - 1/3 - 1/5 = 1/c
III. (15-10-6)/30 = 1/c
IV. -1/30 = 1/c
V. so c.value is -30
Answer: (3x+1)(x−1)
Step-by-step explanation: Factor by grouping.
brainliest or a thank you pls :)
24-8b
24-(8*b)
i don’t know the exact way it is written on your test but it is something along those lines
The answer is:
C: 4^6
For questions like this, you have to add the exponents together.
I will do the hypothesis test.
The null hypothesis is: p <= 0.21
The alternative hypothesis is: p > 0.21
Since the confidence interval for this problem is 95%
The critical value for this is 1.960
So the alpha is .05, the p value is equal to 0.05/2 = 0.025
since it is a 2 tailed test. (letter b)
So p value = 0.025 < 0.5, therefore, reject null
hypothesis. More than 21% like the new soft drink.
