A snail can move 5 inches in 6 minutes. At this rate, how many feet can it move in 48 hours?

Alex Ar [27]

Answer:

2400 inches or 2000 feet is the correct answer

there are 60 minuets in an hour, and 10 sets of 6 minuets, so you multiply 5 by ten to get 50

then you multiply 50 by 48 to get 2400

then you divide by 12 to get 2000 feet

Solve these simultaneous equations. 4x – 7y = – 5 3x – 2y = – 7 Solution: x=

AlexFokin [52]

Answer:

$\huge{x = - \frac{5}{4} + \frac{7}{4} y}$
$\huge{x = - \frac{7}{3} + \frac{2}{3} y}$

Step-by-step explanation:

1. $4x - 7y = - 5$

$4x = - 5 + 7y$

$\boxed{\green{x = - \frac{5}{4} + \frac{7}{4} y}}$

$y E R$

○○•○○

2. $3x - 2y = - 7$

$3x = - 7 + 2y$

$\boxed{\green{x = - \frac{7}{3} + \frac{2}{3} y}}$

$y E R$

Suppose a simple random sample of size nequals36 is obtained from a population with mu equals 74 and sigma equals 6. (a) Descri

OlgaM077 [116]

Part a)

The simple random sample of size n=36 is obtained from a population with

$\mu = 74$

and

$\sigma = 6$

The sampling distribution of the sample means has a mean that is equal to mean of the population the sample has been drawn from.

Therefore the sampling distribution has a mean of

$\mu = 74$

The standard error of the means becomes the standard deviation of the sampling distribution.

$\sigma_ { \bar X } = \frac{ \sigma}{ \sqrt{n} } \\ \sigma_ { \bar X } = \frac{ 6}{ \sqrt{36} } = 1$

Part b) We want to find

$P(\bar X \:>\:75.9)$

We need to convert to z-score.

$P(\bar X \:>\:75.9) = P(z \:>\: \frac{75.9 - 74}{1} ) \\ = P(z \:>\: \frac{75.9 - 74}{1} ) \\ = P(z \:>\: 1.9) \\ = 0.0287$

Part c)

We want to find

$P(\bar X \: < \:71.95)$

We convert to z-score and use the normal distribution table to find the corresponding area.

$P(\bar X \: < \:71.95) = P(z \: < \: \frac{71.9 5- 74}{1} ) \\ = P(z \: < \: \frac{71.9 5- 74}{1} ) \\ = P(z \: < \: - 2.05) \\ = 0.0202$

Part d)

We want to find :

$P(73\:$

We convert to z-scores and again use the standard normal distribution table.

$P( \frac{73 - 74}{1} \:< \: z$
