There are 17 animals in the barn. Some are chickens and some are cows. There are 56 legs in all. How many of each animal are the

Ronch [10]

Answer:

6 chickens, 11 cows.

Step-by-step explanation:

x - chickens

y - cows

x + y = 17

2x + 4y = 56 <-- chickens have 2 legs, cows have 4.

y = -x + 17

Substitute (-x+17) for y in the second equation.

2x + 4(-x + 17) = 56

2x -4x + 68 = 56

2x = 12

<u>x = 6 chickens</u>

Now substitute 6 for x

6 + y = 17

Sodas in a can are supposed to contain an average 12 oz. This particular brand has a standard deviation of 0.1 oz, with an avera

hoa [83]

Answer:

The probability is $P(X < 12) = 0.99286$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 12 \ oz$

The standard deviation is $\sigma = 0.1 \ oz$

The sample mean is $\= x = 12.1 \ oz$

The sample size is n = 6 packs

The standard error of the mean is mathematically represented as

$\sigma_{\= x } = \frac{\sigma}{\sqrt{n} }$

substituting values

$\sigma_{\= x } = \frac{0.1}{\sqrt{6} }$

$\sigma_{\= x } = 0.0408$

Given that the can’s contents follow a Normal distribution then then the probability that the mean contents of a six-pack are less than 12 oz is mathematically represented as

$P(X < 12) = P ( \frac{X - \mu }{ \sigma_{\= x }} < \frac{\= x - \mu }{ \sigma_{\= x }} )$

Generally $\frac{X - \mu }{ \sigma_{ \= x }} = Z (The \ standardized \ value \ of \ X )$

$P(X < 12) = P ( Z < \frac{\= x - \mu }{ \sigma_{\= x }} )$

substituting values

$P(X < 12) = P ( Z < \frac{12.2 -12 }{0.0408} )$

$P(X < 12) = P ( Z < 2.45 )$

From the normal distribution table the value of $P ( Z < 2.45 )$ is

$P (Z < 2.45)0.99286$

=> $P(X < 12) = 0.99286$

Show your work for the right answer

Degger [83]

Answer:

= a^7

Step-by-step explanation:

Given in the question,

a^5 * a^4 / a²

To find,

show working

<h3>Explanation</h3>

As we know that to divide exponents (or powers) with the same base, we subtract the exponents. Division is the opposite of multiplication, so when multiplying the exponents (or powers) with the same base add the exponents.

<h3>Working</h3>

a^5 * a^4 / a²

= a^(5 + 4) / a² (Multiplying)

= a^9 / a²

= a^(9 - 2) (Dividing)

= a^7

<em>hence shown</em>
