Name the pair of complementary angles and pair of supplementary angles​

Mathematics
1 answer:
LUCKY_DIMON [66]3 years ago
8 0

Complementary angles are those angles whose sum is 90

Supplementary angles are those angles whose sum is 180

<QTS= 150

<RTS=60

<VWU= 30

Hence <QTS + <VWU = 150+30= 180 are supplementary angles

and <RTS + <VWU= 60+30 = 90 are complementary angles

In order to determine an interval for the mean of a population with unknown standard deviation, a sample of 24 items is selected
nikitadnepr [17]

If the sample size of population is 24 then the number of degrees of freedom for reading the t  value is 23 which is option c.

Given sample size of 24,mean 23.

We have to determine the number of degrees of freedom which will be used to find the critical values of t.

Degree of freedom is the number of values in the final calculation of a statistic that are free to vary means that can change their values in the formula of calculating t.

t=(X-μ)/s/\sqrt{n}

where X is sample mean ,

μ is hypothsised population mean

s is sample standard deviation

n is sample size.

Degree of freedom=n-1

In this question n is 24 so the degree of freedom =24-1=23.

Hence the number of degrees of freedom for reading the t value is 23.
