Find the Supplement to 101

Supplementary angles = 180 degrees

180 = 101 + unknown Subtract 101 from 180

unknown = 79

Because the upper triangle is marked as having 2 equal sides, the left angle is also 79 degrees,

Now the vertex angle is 79 + 79 + y = 180 All triangles have 180 degrees

158 + y = 180 Subtract 158 from both sides

y = 180 - 158

y = 22

y is vertically opposite the vertex angle of the lower triangle. Both the sides are marked as equal, so the angles opposite them are equal as well.

x + x + 22 = 180 Combine

2x + 22 = 180 Subtract 22 from both sides.

2x = 180 - 22

2x = 158 Divide by 2

x = 158/2

x = 79

A school was attempting to determine the proportion of students who have access to the internet in their homes. Demographic data

Likurg_2 [28]

Answer:

Z = -1.789

P value = 0.036807

Step-by-step explanation:

Here

H0: p = 0.85 students will have access to the internet at home

Ha: p < 0.85 students will have access to the internet at home

As per the given data, out of 120 sampled students, 95 have access to internet at home

This is 79.17 % of the total number of sampled students.

The Z values is given by

$Z = \frac{p-p'}{\sqrt{\frac{p(1-p)}{n} } }$

Substituting the given values, we get -

$Z = \frac{0.7917-0.85}{\sqrt{\frac{0.85(1-0.85)}{120} } }\\Z = -1.789$

The sample proportion of 0.7917 is about -1.789 standard errors below the population proportion given in the null hypothesis.

Considering, result is significant at p < .05, the P-Value is .036807.

Find the x intercept(s) y= -x^2 + 2

VashaNatasha [74]

Answer:

$(\pm \sqrt{2}, 0)$

Step-by-step explanation:

The x intercepts are basically the points at which y = 0.

-x^2 + 2 = 0

-x^2 = -2

x^2 = 2

x = $\pm \sqrt{2}$
