Kassie recorded the favorite sport of students at her school. She surveyed 800 students. How many more students chose Baseball t

lisov135 [29]

Answer:

40 more kids chose baseball over basketball.

Step-by-step explanation:

The best way to go about this is to use benchmark percentages.

For baseball, 25% of 800 people chose that, so we can do 800/4 to get 200, so 200 students chose baseball

For basketball, we could do 800/5 but that isn't mental math, so we can do 10% of 800 is 80 and 80*2=160. So 40 more kids chose baseball over basketball.

Karo-lina-s [1.5K]

Answer:

$\sqrt{10}$

Step-by-step explanation:

$g(4) = \sqrt{(4)^2 - (4) - 2} \\\\g(4) = \sqrt{16 - 4 - 2} \\\\g(4) = \sqrt{16 - 6} \\\\g(4) = \sqrt{10}$

You can't simplify this anymore

For the function defined by:

Eva8 [605]

The first function is represented by the green line, while the second is represented by the orange line

<h3>What are piecewise functions?</h3>

Piecewise functions are functions that have at least 2 sub functions, each of which have different intervals

The function is defined by

$f(x) = \left \{ {{x^2,\ x\le1} \atop {2x + 1,\ x > 1}} \right.$

<h3>(a) Graph the first function</h3>

The first function in f(x) is defined by

$f(x) = x^2, \ x \le 1$

See attachment for the graph of the first function

<h3>(b) Graph the second function</h3>

The second function in f(x) is defined by

$f(x) = 2x + 1, \ x > 1$

See attachment for the graph of the second function
