in short, we simply divide the whole of 45 by (7+4+3+1), and then distribute accordingly, let's do that,

\bf \cfrac{45}{7+4+3+1}\implies \cfrac{45}{15}\implies 3 \\\\[-0.35em] ~\dotfill\\\\ \stackrel{Stephen}{7(3)}~:~\stackrel{Marley}{4(3)}~:~\stackrel{David}{3(3)}~:~\stackrel{Katherine}{1(3)}\implies \stackrel{Stephen}{21}:\stackrel{Marley}{12}:\stackrel{David}{9}:\stackrel{Katherine}{3}

lora16 [44]

Answer: Type  I error would be a conclusion that average time spent on phone by teenager is higher than 4.5 hours per week which is actually the same.

Step-by-step explanation:

Type 1 error occurs when a null hypothesis is true but researcher rejects it.

Let \mu be the average time spent on the phone by teenagers .

Here, Null hypothesis: H_0:\mu=4.5

Alternative hypothesis : H_a: \mu>4.5

So, Type  I error would be a conclusion that average time spent on phone by teenager is higher than 4.5 hours per week which is actually the same.

Use the inverse variation equation to fill in the table.
Mandarinka [93]

The value of a is  0.10.

The value of b is 20.78.

The value of c is 0.02.

<h3>What are the missing values?</h3>

When two variables have inverse variation, the two variables move in opposite directions. If one variable increases, the other decreases.

p = 8.31 / V

V = 8.31 / p

a = 8.31 / 83.1 = 0.10

b = 8.31 / 0.4 = 20.78

c = 8.31 / 415.5 = 0.02

Area of a triangle is (basexheight)/2

That's what your Formula, then you have to plug in the numbers

so the algebraric expression is (5xn)/2

For then end if you look at the patteren for the height it goes by 2. So the last height would be 10.
Plug that into the equation, which would be (5x10)/2=25
