Answer:

88 Vegetarian Wraps Sold.

Step-by-step explanation:

This is a System of Equations Problem.

Your Two Systems Are:

v(1)+c(2.7)=244.6 and c+v=146

c = chicken wraps and v = vegetarian wraps

Each chicken wrap costs $2.70 (2.7). Put the variable of c next to (2.7) meaning to multiply.

Each vegetarian wrap costs $1 (1). Put the variable of v next to (1)

244.60 (244.6) is the total amount of money made from selling the wraps. This will be the total of the equation.

v(1)+c(2.7)=244.6

Solve 2.7c+v=244.6 for v.

Add -2.7c to both sides.

2.7c+v+−2.7c=244.6+−2.7c

v=−2.7c+244.6

Substitute −2.7c+244.6 for v in c+v=146.

c+v=146

c+−2.7c+244.6=146

Simplify both sides of the equation.

−1.7c+244.6=146

Add -244.6 to both sides.

−1.7c+244.6+−244.6=146+−244.6

−1.7c=−98.6

Divide both sides by -1.7.

\frac{-1.7c}{-1.7} =\frac{-98.6}{-1.7}

c=58

Substitute 58 for c in v=−2.7c+244.6.

v=−2.7c+244.6

v=(−2.7)(58)+244.6

Simplify both sides of the equation.

v=88

Answer:

c=58 and v=88

88 vegetarian wraps were sold.

Question is in picture below ​
klasskru [66]

Answer:

\frac{y - 18}{x - 1}  =  \frac{23 - 18}{1.5 - 1}  =  \frac{5}{0.5}  = 10 \\ y - 18 = 10(x - 1)  = 10x - 10 \\ y = 10x  + 18 - 10 = 10x + 8 \\  \boxed{f(x) = 10x + 8}

<h2>A. is the right answer.</h2>

hope this helps.

The sample mean is x = 12.8%. let x be a random variable that represents the percentage of wheat crop in that county lost to hai
katen-ka-za [31]
Given that \bar{x}=12.8\% and \sigma=5.0\%, given that the population mean is \mu=11\% and the sample size is n = 16, the test statistic is given by

z= \frac{\bar{x}-\mu}{\sigma/\sqrt{n}}  \\  \\ = \frac{12.8-11}{5/\sqrt{16}}  \\  \\ = \frac{1.8}{5/4} = \frac{1.8}{1.25}  \\  \\ =1.44 \\  \\ \Rightarrow p-value=p(z\ \textgreater \ 1.44) \\  \\ =1-P(z\ \textless \ 1.44)=1-0.92507 \\  \\ =0.07493

Since the test is a two tailed test, the p-value is 2(0.07493) = 0.14986

Since the p-value is greater the significant level of α = 0.01, thus, we fail to reject the null hypothesis and conclude that there is no sufficient evidence that <span>the percentage of wheat crop lost to hail in that county is different from the national mean of 11%</span>.
