Answer:

8,250

Step-by-step explanation:

step 1

we know that

For a total of 500 students, 33% chose a cell phone as their favorite electronic device

so

The number of students that chose a cell phone as their favorite electronic device is equal to

500(33/100)=165\ students

step 2

If 25,000  students were surveyed, how many would you expect to chose a cell phone as their favorite electronic device?

using proportion

\frac{500}{165}=\frac{25,000}{x}\\\\x=165(25,000)/500\\\\x= 8,250

An arrow is shot vertically upward from a platform 45 feet high at a rate of 168 ft/sec. Use the quadratic function
Maksim231197 [3]

Answer:

5.3 s

Step-by-step explanation:

a) since the height is defined by a function, we can find the turning point of the quadratic , which is where the ball will have the highest point. The turning point is where the gradient is equal to zero so we differentiate first

h(t) = -16t^{2} + 168t + 45\\h'(t)= -32t+168\\0=-32t+168\\t=5.3s

JulsSmile [24]
To answer this question, we would have to use algebra.

(4x-5)+2(3x+1)<br> Can you help me solve this plz for me
Korvikt [17]

Answer:

10x - 3

Step-by-step explanation:

First, distribute 2 to all terms within the second parenthesis:

2(3x + 1) = (2 * 3x) + (2 * 1) = 6x + 2

4x - 5 + 6x + 2

Combine like terms (terms with the same amount of variables).

4x + 6x + 2 - 5

(4x + 6x) + (2 - 5)

10x + (-3)

10x - 3

10x - 3 is your answer.
