Answer:

Y=k.x "k" is my constant of proportionality.

From 1st reading.

K=y/x=6/(2/3)

K=9

When y=12

X=y/k

X=12/9=4/3

Answer:

We accept H₀

Step-by-step explanation:

Normal Distribution

size sample n = 69

sample mean 18.94

standard deviation 8.3

Is a one tailed-test to the left we are traying of find out is we have enough evidence to say that the mean is less than 20 min.

1.-Test hypothesis H₀ ⇒ μ₀ = 20

Alternative hypothesis Hₐ ⇒ μ₀ < 20

2.- Critical value

for α = 0.1 we find from z Table

z(c) = - 1.28

3.-We compute z(s)

z(s) = [ ( μ - μ₀ ) / (σ/√n) ⇒ z(s) = [( 18.94 - 20 )*√69)/8.3]

z(s) = ( -1.06)*8.31/8.3

z(s) = - 1.061

4.- We compare

z(c) and z(s) -1.28 > -1.061

Then z(c) > z(s)

z(s) in inside acceptance region so we accept H₀

Chester and Mary have pencils in a ratio of 2:4. Together they have 24 pencils. What percentage of the total pencils does Mary h

weeeeeb [17]

She has 67% of the pencils.

Chester:Mary = 2:4 = 1:2
So, in the simplest case:
If Chester has one pencil Mary would have two.
There are three pencils.
Mary has two.
2/3 = 0.667 = 67% (rounded)

A right come has a volume of 24pie cubic meters and a radius of 3 meters find the height of the cone

JulijaS [17]

Hello!

The equation for find the h when given volume and radius is

$h = 3 \frac{V}{ \pi r^{2} }$

h is height
v is volume
r is radius

Put in the values you know

$3 \frac{24 \pi }{ \pi 3^{2} }$

Since there is pi on the top and bottom we can get rid of it

multiply the 3 by the top number

$\frac{72}{9}$

the answer is 8m

Hope this helps!
