Adam is building a rectanglar swimming pool. The perimeter of the pool must be no more then 120 feet. If the length of the pool

jasenka [17]

Answer:

$W\leq 38\ ft$

The maximum width must be $38\ ft$

Step-by-step explanation:

Let

L ----> the length of the rectangular pool

W ---> The width of the rectangular pool

we know that

$P\leq 120\ ft$

$P=2(L+W)$

$2(W+L)\leq 120$ ----> inequality A

we have

$L=22\ ft$

substitute the value of L in the inequality A

$2(W+22)\leq 120$

simplify

$(W+22)\leq 60$

$W\leq 60-22$

$W\leq 38\ ft$

The maximum width must be $38\ ft$

Two owners of a cattle ranch, Jo and Val, want to find the average weight for the ranch's 200 cows. Instead of weighing all of t

Zolol [24]

Answer:

The value is $E =19.6$

Step-by-step explanation:

From the question we are told that

The mean of Jo cows is $\= x_1 = 1350$

The standard deviation of Jo cow is $s_1 = 50$

The mean of Val cows is $\= x_2 = 1420$

The standard deviation of Val cows is $s_2 = 50$

The sample size for both Val and Jo is n = 25

Let assume that the level of significance is $\alpha = 0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }$

Hence margin of error for Jo is

=> $E = 1.96 * \frac{50}{\sqrt{25} }$

=> $E =19.6$
