Answer:

these are supplementary

and x = 50

Step-by-step explanation:

one straight line = 180 degrees

there are only two angles making up this 180 degree line, so by definition they are supplementary

76 + 2x + 4 = 180

80 + 2x = 180

2x = 100

x = 50

$( 3 {x}^{2} - 13x - 10 ) \div (x - 5) = \\$

$\frac{3 {x}^{2} - 13x - 10 }{x - 5} = \\$

$\frac{(x - 5)(3x + 2)}{(x - 5)} = \\$

$3x + 2$

Rus_ich [418]

Luke's original decimal is 0.20 and Bekka's is 0.30 so 0.40 and 0.50 would be greater than Luke's original and 0.20 and 0.10 are lesser than Bekka's original decimal

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

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

$t = 3.744$
