In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angl

e.
A straight line is shown and is marked with three angles. The first angle measures 50 degrees. The second angle measures 60 degrees. The third angle is labeled x. The line between the 40 degree angle and angle x extends below the straight line. The angle formed is labeled angle y.

Write and solve an equation to determine the measure of angle y.

Suppose that you take 1000 simple random samples from a population and that, for each sample, you obtain a 95% confidence interv
Bogdan [553]

Using the interpretation of a confidence interval, it is found that approximately 950 of those confidence intervals will contain the value of the unknown parameter.

A x% confidence interval means that we are x% confident that the population mean is in the interval.

  • Out of a large number of intervals, approximately x% will contain the value of the unknown parameter.

In this problem:

  • 95% confidence interval.
  • 1000 samples.

0.95 x 1000 = 950

Hence, approximately 950 of those confidence intervals will contain the value of the unknown parameter.

HELP GEOMETRY 10 POINTS
Over [174]
A, because 
rectangle- at least 1 angle should be 90 degrees.
square- all angles and sides should have the same measures.
quadrilateral- its any shape with 4 sides.
parallelogram-both pairs of opposite sides parallel and congruent.
rhombus-diagonals are perpendicular which means the angle of the perpendicular lines would be 90 degrees.

A group walked 3/8 mile in 1/5 hour. Which is the groups walking speed in miles per hour
gogolik [260]

Answer:

The groups walking speed is 1\frac{7}{8}\frac{miles}{hour}  or 1.875\frac{miles}{hour}

Step-by-step explanation:

we know that

To find the speed divide the distance by the time

so

\frac{(3/8)}{(1/5)}=\frac{15}{8}\frac{miles}{hour}

Convert to mixed number

\frac{15}{8}=\frac{8}{8}+\frac{7}{8}=1\frac{7}{8}\frac{miles}{hour}
