= square_root(13)
= 3.61

Please help me is this statement true or false 3(36 - 11) = 45?

viva [34]

Hi there! The answer is FALSE

To find the answer we need to work out the parenthesis.
$3(36 - 11) =$
$3 \times 36 - 3 \times 11 =$
$108 - 33 =$
$75$

75 does not equal 45 and therefore the statement is false.

Answer:

The test statistic is $t = 3.744$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 140$

The The level of significance is $\alpha = 0.05$

The sample size is n = 18

The null hypothesis is $H_o : \mu = 140$

The alternative hypothesis is $H_a : \mu > 140$

The sample mean is $\= x = 155$

The standard deviation is $\sigma = 17$

Generally the test statistics is mathematically represented as

$t = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }$

substituting values

$t = \frac{ 155 - 140 }{ \frac{ 17 }{ \sqrt{18} } }$

$t = 3.744$

Define and compare radian measure to degree measure

Lelechka [254]

Radian: is the standard unit of angular measure, used in many areas of mathmatics.
degree: is a measuement of plane angle, defined by representing a full rotation as 360 degrees.

Both are two units for measuring angles. There are at least four such units, but degrees and radians are most likely to encounter high school and college.
