Answer:

Number line with numbers negative 4, negative 3, negative 2, negative 1, 0, 1, 2, 3, 4 labeled. A dot is made at 2.6 and labeled as square root of 7

Step-by-step explanation:

* Lets explain how to solve this problem

- We want to know the position of √7 on the number line, then:

1- Square the √7

# (√7)² = 7

2- Search 7 is between which two square numbers

# 7 is between 4 and 9 which are square numbers

3- ⇒ 4 < 7 < 9 ⇒ take √ for all

# 2 < √7 < 3

∴ The value of √7 is between 2 and 3

* Lets look to the answer to find the correct answer

∵ The first answer is:

A dot is made at 1.7 and labeled as square root of 7

∵ 1.7 is not between 2 and 3

∴ The first answer is not true

∵ The second answer is:

A dot is made at 2.6 and labeled as square root of 7

∵ 2.6 is between 2 and 3

∴ The second answer is true

∴ Number line with numbers negative 4, negative 3, negative 2,

negative 1, 0, 1, 2, 3, 4 labeled. A dot is made at 2.6 and labeled

as square root of 7

Solving Exponential and Logarithmic Equation In exercise,solve for x or t.See example 5 and 6.

Virty [35]

Answer:

$x=\frac{6e^3}{e^3-1}$

Step-by-step explanation:

$ln x - ln(x - 6) = 3$

Apply natural log property

ln mn=ln m + ln(n), ln(m/n)=ln(m)-ln(n)

$ln x - ln(x - 6) = 3$

$ln(\frac{x}{x-6} )=3$

All natural log has base 'e'

$\frac{x}{x-6} =e^3$

cross multiply

$x=e^3(x-6)$

$x=e^3x-6e^3$

add 6e^3 on both sides and -x on both sides

$6e^3=e^3x-x$

$6e^3=x(e^3-1)$

Divide e^3-1 on both sides

$x=\frac{6e^3}{e^3-1}$

You buy halibut at $27 per pound. One portion of seared halibut requires 6 ounces of halibut. How much does the halibut for one

Veronika [31]

Answer:

$10.12

Step-by-step explanation:

first, find the price of one ounce of halibut, by dividing $27 by 16 because there are 16 ounces in a pound, and you get 1.6875. then you multiply that by how many ounces you are buying, which is 6, so your answer is 10.125. round to the nearest cent.

The rejection region is give by

$|z_{test}|\ \textgreater \ z_{\alpha/2}$

where the test statistics is given by

$\frac{\bar{x}-\mu}{\sigma/\sqrt{n}} = \frac{980-1000}{100/\sqrt{75}} \\ \\ = \frac{-20}{100/8.6603} = \frac{-20}{11.5470} =-1.73$

i.e. $|z_{test}|=|-1.73|=1.73$

Thus, $z_{\alpha/2}=1.73$

Using the statistical table, the level of the test is 0.04.
