K=1/2 mv squared, determined m when v=30 and k=4500.
WITCHER [35]

Given the expression:

\text{ k = }\frac{1}{2}mv^2

At v = 30 and k = 4,500 , let's determine m.

\text{ k = }\frac{1}{2}mv^2\frac{2k}{v^2}\text{ = m }\rightarrow\text{ m = }\frac{2k}{v^2}

We get,

\text{ m = }\frac{2k}{v^2}\text{ = }\frac{2(4,500)}{(30)^2}\text{ = }\frac{9,000}{900}\text{ m = 10}

Therefore, m = 10.

PLS I NEED HELP I ONLY HAVE 15 MINS I BEG YOU PLEASE!! :(
gogolik [260]

To solve this, we need to use the z statistic. The formula for z score is:

z = (x – u) / s

where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2

z = (90 – 90.6) / 17.2

z = -0.035

From the standard distribution tables:

P (z = -0.035) = 0.4860

Therefore there is about 48.60 % chance that it will be less than 90 pounds
