Do the ratios 8:10 and 5:4 form a proportion?

sukhopar [10]

No because 8 is to 5 and 10 is to 4, they aren’t connected. Or you can do 8/10= .8 and 5/4= 1.25, they are not the same

Suppose a large shipment of telephones contained 21% defectives. If a sample of size 498 is selected, what is the probability th

grandymaker [24]

Answer:

$P(-3\% < x < 3\%) = 0.901$

Step-by-step explanation:

Given

$p = 21\%$

$n = 498$

Required

$P(-3\% < x < 3\%)$

First, we calculate the z score

$z = \sqrt{p * (1 - p)/n}$

$z = \sqrt{21\% * (1 - 21\%)/498}$

$z = \sqrt{21\% * (79\%)/498}$

$z = \sqrt{0.1659/498}$

$z = \sqrt{0.000333}$

$z = 0.0182$

So:

$P(-3\% < x < 3\%) = P(-3\%/0.0182 < z$

$P(-3\% < x < 3\%) = P(1.648 < z$

From z probability, we have:

$P(-3\% < x < 3\%) = 0.901$

Label the slope and y intercept

hjlf

The y-intercept will be 8
And then you work out the slope by replacing the c, y and the x in y=mx+c
The y and x will be any of the coordinates above
So it will be 0=m(8)+(8)
0=8m+8
So 8m=-8
Therefore m=-1
So the y-intercept is 8 and the slope is -1

Find the volume of the sphere and use 3.14 for T. You may

nirvana33 [79]

Answer:

The answer is C. 904.32 in^3.

Step-by-step explanation:

To find the volume of a sphere with a radius of 6 in, start by using the formula for a sphere, which is V= $\frac{4}{3}$ $\pi$ $r^{3}$ . However, for this formula instead of using ( $\pi$ ), 3.14 will be used.

Now, plug the radius into the formula, and solve for V.

Finally, the answer will be 904.32 in^3.
