Hi,
So if I read correctly, there are 788 students each getting one of four colors of t-shirts (and there are an equal number of shirts per color). To do this, all you need to do is divide the number of students (788) by the number of colors (4) to see how many students get each color of t-shirt.

788 ÷ 4 = 197

Red is one of the four colors, and 197 is exactly one fourth of the students, so one-fourth of the students (197) get red.

a coin lands on heads 200 times. the relative frequency of heads is 0.4. how many times was the coin thrown?
Kazeer [188]

Answer:

The number of times coin thrown was <u>500</u>.

Step-by-step explanation:

Given:

A coin lands on heads 200 times. the relative frequency of heads is 0.4.

Now, to find the times coin was thrown.

Let the number of times coin thrown was be x.

Relative frequency = 0.4.

Number of lands on heads = 200.

So, to get the number of times coin was thrown we put formula:

Relative\ frequency=\frac{Number\ of\ lands\ on\ heads}{Number\ of\ times\ coin\ thrown}

0.4=\frac{200}{x}

<em>By cross multiplying we get:</em>

0.4x=200

<em>Dividing both sides by 0.4 we get:</em>

x=500.

Therefore, the number of times coin thrown was 500.

What is the answer to 1.1x + 1.2x - 5.4 = -10
lord [1]
1.1x+1.2x-5.4=-10

11/10x+12/10x-54/10=10

11x/2.5+2^2-1*3/5x-3^3/5=-10

(11x)+2(2*3x)+2(-3^3)/2*5=-10

11x+2(6x)+2(-27)/2*5=-10

11x+2*6x-2*27/2*5=-10

11x+12x-54/2*5=-10

23x-54/2*5=-10

23x-54=-100

23x=-46

23x/23=-46/23

x=-2*23/23

x=-2
