Answer:

No the answer is incorrect

Step-by-step explanation:

2*1.5-5=-1

3-5=-1

-2=-1

-1 and -2 are not the same

Place the x (1.5) and y (5) values into the equation, and solve. If the statement you get is true, it is a solution.

2x - y = -1​

2(1.5) - 5 = -1​

3 - 5 = -1

-2 ≠ -1

Since this is a false statement, negative 2 is not equal to -1, the ordered pair is NOT a solution. I hope this helps and have a great day!

Yuliya22 [10]

Answer:

17% of the bill

Step-by-step explanation:

Well to find the answer to this question we first have to add 35 + 48 to get the total percent of the bill that Michelle and Lori paid.

35 + 48 = 83%

now that we know the percent of the bill that Lori and Michelle are paying we have to subtract that amount by 100% to get the percent of the bill that Patti is paying.

100% - 83% = 17%

To compare two products such as colas, a random sample is selected to taste two types of colas (A and B). Each selected subject
Nadya [2.5K]

Answer: The sample size would be needed = 385

Step-by-step explanation:

Let p be the prior population proportion.

Margin of error = E

When not estimate of p is given , the formula to calculate the minimum sample size <em>n</em> = 0.25(\dfrac{z^*}{E})^2 , where z* = critical value for given confidence interval.

Here z* for 95% confidence level is 1.96.

E=5%=0.05

Then n=0.25(\dfrac{1.96}{0.05})^2\approx385

Hence, the sample size would be needed = 385
