Booker has 85 video games .he has 3 shelves to put them on .each shelf can hold 40 games.how many more games can fit in the shel

LiRa [457]

So you know that Booker has 85 video games and that he has 3 shelves to put each of them on. And you also know that each shelf can hold 40 games.
So if you multiply 40 games by 3 shelves to find the total number of games that he can put on all the shelves, you will get 120 games.
You know that Booker has 85 video games, and you can fit 120 video games on all the shelves.
To find how many more games Booker can fit in the shelves, you subtract 120 by 85, and you will get 35 video games.
So, Booker can fit 35 more video games in the shelves.

I hope this helps :)

A linear function has a slope of Negative StartFraction 7 Over 9 EndFraction and a y-intercept of 3. How does this function comp

Svet_ta [14]

Answer:

They are the same line written in different forms.

Step-by-step explanation:

Given a linear function with a slope of $-\frac{7}{9}$ and a y-intercept of 3.

The equation of the line in the slope-intercept form is given as:

$y=-\frac{7}{9}x+3$

Given the other line,

$y+11=-\frac{7}{9}(x-18)$

Simplified:

$y+11=-\frac{7}{9}x+14\\y=-\frac{7}{9}x+14-11\\y=-\frac{7}{9}x+3$

The two lines are one and the same line.

Mandarinka [93]

Answer:

(a) Confidence Interval for Route A is (38.61, 41.39)min

Confidence Interval for Route B is (42.07, 43.93)min

(b) No

Step-by-step explanation:

(a) Route A

Mean=40min, sd=3min, df=33.1, t=2.0675, n=20

CI = (mean + or - t×sd/√n)

CI = (40 + 2.0675×3/√20) = 40+1.39 = 41.39min

CI = (40 - 2.0675×3/√20) = 40 - 1.39 = 38.61min

CI for Route A is (38.61,41.39)min

Route B

Mean=43min, sd=2min, t=2.0675, n=20

CI = (43 + 2.0675×2/√20) = 43+ 0.93 = 43.93min

CI = (43 - 2.0675×2/√20) = 43 - 0.93 = 42.07min

CI for Route B is (42.07,43.93)min

(b) He should not believe the old timer's claim. The man saves an average of 3 minutes a day by driving Route A
