Answer:
28.27
Step-by-step explanation:
This is a false statement because you cannot solve it
The answer would be 5/8 and 0.625 in decimal form.
1/-4 - 1/2 * 7/-4 (divide then multiply)
1/-4 - 1 * 7 over 2 * -4 (multiply)
1/-4 - 7 over 2 * -4 (simplify 1 * 7 to 7)
1/-4 - 7/-8 (simplify 2 * -4 to -8)
1/-4 - (7/-8) (move the negative sign to the left)
1/-4 + 7/8 (simplify brackets)
5/8 (simplify).
Answer:
( 5/2, 2 )
Step-by-step explanation:
Solve by substitution method:

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.
