Sally is planning a trip for 225 students

Mathematics
1 answer:
Gala2k [10]3 years ago
4 0

Answer: 75 students.

Step-by-step explanation:

In the data set we have a total of 10 + 8 + 7 + 5 = 30 students.

of those, 10 want to go to the park, the percentage is:

(10/30)*100% = 33.3%

Then, out of the 225, we can expect that a 33.3% (or 0.333 in decimal form) want to go to the park, this is:

N = 225*0.333% = 74.925

We can roud it up, and get N = 75

So Sally can expect that 75 students want to go to the park

Find the midpoint of a line segment that has the endpoints (3,5) and (5,-3) *
igor_vitrenko [27]

Answer:

<h3>The answer is (4 , 1)</h3>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )\\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3,5) and (5,-3)

We have

M = ( \frac{3 + 5}{2}  , \frac{5 - 3}{2} ) \\  = ( \frac{8}{2} , \frac{2}{2} )

We have the final answer as

<h3>(4 , 1)</h3>

Hope this helps you

Which graph below solves the following system of equations correctly? y = three over four times x squared minus 3 y = negative t
Zielflug [23.3K]
Let's rewrite the system of equations:
 y = three over four times x squared minus 3
 y = (3/4) x ^ 2 - 3
 y = negative three over four times x squared plus 3
 y = (-3/4) x ^ 2 + 3
 The system of equations is:
 y = (3/4) x ^ 2 - 3
 y = (-3/4) x ^ 2 + 3
 The solutions are:
 (-2, 0)
 (2, 0)
 Answer:

Write g(f(x)) as an expression in terms of x
yawa3891 [41]

An expression is defined as a set of numbers, variables, and mathematical operations. The value of g(f(x)) is (x²-10x+13) / (x²-10+29).

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The complete questions is,

Write g(f(x)) as an expression in terms of x

f(x) = x-5

g(x) = \dfrac{x^2-12}{x^2+4}

The value of g(f(x)) as an expression in terms of x can be written as,

g(f(x)) = \dfrac{(x-5)^2-12}{(x-5)^2+4}\\\\\\g(f(x)) = \dfrac{x^2+25-10x-12}{x^2+25-10x+4}\\\\\\g(f(x)) = \dfrac{x^2-10x+13}{x^2-10+29}

Hence, the value of g(f(x)) is (x²-10x+13) / (x²-10+29).
