Finddddd the value of x

Mathematics
2 answers:
Sloan [31]2 years ago

Answer:

1)x = 30°

2) x = 46°

3) x = 20°

4)x = 53°

Step-by-step explanation:

<h3>Angle sum property of triangle: </h3>

  The sum of all three angles of a triangle is 180°.

1) x + 60 + 90 = 180

          x + 150 = 180

                    x = 180 - 150

                    \sf \boxed{\bf x = 30^\circ}

2)  57 + 77 + x = 180

           134 + x = 180

                     x = 180 - 134

                     \sf \boxed{\bf x = 46^\circ }

3) 134 + 26 + x = 180

          160 + x  = 180

                   x = 180 - 160

                   \sf \boxed{\bf x = 20^\circ}

4) 65 + 62 + x = 180

           127 + x = 180

                     x = 180 - 127

                     \sf \boxed{x = 53^\circ}

What is the slope of a line perpendicular to the line whose equation is 4x-2y=-16.
Arte-miy333 [17]

Answer:

-1/2

Step-by-step explanation:

the slope of the first line is 2

to get the line perpendicular, you swap the numerator and denominator, then if positive make negative and the other way around

Using a sequencing method called "RNAseq," a researcher determines the level of FOXP2 expression
Wewaii [24]

The Z-score is 2.306 to three decimal places. However, the Z-test statistic value shows that it is greater than the Z-critical value, so we reject the null hypothesis \mathbf{H_o}

<h3>What is the Z-score of a test statistic?</h3>

A z-score is a measurement of how often standard deviations the score obtained from a z-test is beyond or under the mean population.

From the given data information, let us find the mean and the standard deviation.

\mathbf{Mean (\bar  x) = \dfrac{1154+5998+1007+...3987+4187+887}{10}}

\mathbf{Mean (\bar  x) = \dfrac{24256}{10}}

Mean (x) = 2425.6

The hypothesis testing can be computed as:

\mathbf{H_o: \mu = 2425.6}

\mathbf{H_1: \mu \ne 2425.6}

The standard deviation (σ) is:

\mathbf{=\mathbf{ \sqrt{\dfrac{(1154-2425.6)^2+....+(887-2425.6)^2}{10-1}}}}

\mathbf{= \sqrt{3199489}}

= 1788.71

Now, the Z-test statistic is determined using the formula:

\mathbf{|Z| = |\dfrac{\bar x - \mu }{\sigma}| }

\mathbf{|Z| = |\dfrac{2425.6 -6550 }{1788.71}| }

\mathbf{|Z| = |-2.3058|  }

Z ≅ 2.306  

Therefore, at a 0.05 level of significance, the Z-critical value is 2.306. However, since the Z-test statistic value shows that it is greater than the Z-critical value, so we reject the null hypothesis \mathbf{H_o}

The complete question is given as:

Using a sequencing method called "RNAseq," a researcher determines the level of FOXP2 expression in 10 different samples of lung tissue, and obtains these data:

  • 1154 5998 1007 2501 1000 988 2547 3987 4187 887

Scientist has previously determined that FOXP2 is expressed in brain tissue at a level of 6,550. Calculate the Z-score associated with a test to see if the average expression of FOXP in her lung tissue samples is different from the levels she measured from brain tissue.
