Answer:

She is wrong because Dave's restaurant is more expensive

Step-by-step explanation:

You have to put a number into the formula to work out if its true

Let's say you change g to 10 guests

Diana's one would be 250+250=500

Dave's one would be 100+450=550

This means that she is wrong because it would be an extra 50 for Dave's place.

Answer:

$x=\frac{-7+-\sqrt{37} }{6}$

Step-by-step explanation:

This (±) goes between the $-7$ and $\sqrt{37}$

$3x^{2} +7x+1=0$

$ax^{2} +bx+c$

$-b$ ± $\sqrt{b^2-4ac}$ /2a

$-7$ ± $\sqrt{(7)^2-4(3)(1)}$ /2(3)

$-7$ ± $\sqrt{49-12}$ /6

$-7$ ± $\sqrt{37}/6$

PLEASE HELP! - The scatterplot below shows the number of weeks that students have been in keyboarding class and the number of mi

Setler [38]

Solution: Which statement about the scatter plot is true?

The correct answer is option A. As the number of weeks in class increases, the number of keyboarding mistakes decreases.

Explanation: From the scatter plot, we clearly see there exists a negative linear relationship between the number of weeks in class and the number of mistakes. And we know that if there exists a negative linear relationship between the two variables, then the values of two variables move in opposite direction. If the values of one variable goes up, the values of other variable go down. From the given scatter plot, we clearly see the number of mistakes goes down as the number of weeks in class increases. Therefore, the option A is correct
