Answer:

i hope this helps you :))

Step-by-step explanation:

132

Linear pairs always equal 180 degrees.

Therefore, Angle ABC + Angle CBD =180.

We already know Angle CBD is 48.

Therefore, Angle ABC + 48 =180

Subtraction Property of Equality:

Angle ABC = 180-48= 132 Degrees.

Assume that you want to test the claim that the paired sample data come from a population for which the mean difference is μd =

swat32

Answer:

Test statistic, $t_{s} = -0.603$ (to 3 dp)

Step-by-step explanation:

Deviation, d = x -y

Sample mean for the deviation

$\bar{d} = \frac{\sum x-y}{n}$

$\bar{d} = \frac{(28-6) + (31-27)+(20-26)+(25-25)+(28-29)+(27-32)+(33-33)+(35-34)}{8} \\\bar{d} = -0.625$

Standard deviation: $SD = \sqrt{\frac{\sum d^{2} - n \bar{d}^2}{n-1} }$

$\sum d^{2} = (28-26)^2 + (31-27)^2 +(20-26)^2 +(25-25)^2 +(28-29)^2 +(27-32)^2 +(33-33)^2 +(35-34)^2\\\sum d^{2} = 63$

$SD = \sqrt{\frac{63 - 8 * (-0.625)^2}{8-1} }$

SD =2.93

Under the null hypothesis, the formula for the test statistics will be given by:

$t_{s} = \frac{ \bar{d}}{s_{d}/\sqrt{n} } \\t_{s} = \frac{- 0.625}{2.93/\sqrt{8} }$

$t_{s} = -0.6033$

A computer programm contains one error.in order to find the error, we split the program in to blocks and test 2 of them,selected

kolezko [41]

If the E(X) = 1 then that means it has a 100% which is incorrect.
Each block has an equal probability to contain the error so 1/3 because you choose 2/6.

Can someone help solve for Y

kotykmax [81]

Because angleCBD＋angleBDC＋angleC＝180 so angleCBD＋angleBDC＝180－angleC＝180－82＝98 because BC＝DC so angleCBD＝angleBDC so 2 angleCDB＝98 so angleCDB＝49 so y＝29 by Joy Xu，紫馨雪汐
