Answer:

The area of the lighter shaded region = 38.1 cm²

Step-by-step explanation:

It is given a circle with a sector and a triangle

Radius of circle = 6 cm

<u>To find the area of sector</u>

Area of circle = πr²

 = 3.14 * 6²

 = 3.14 * 36

 = 113.04 cm²

Central angle of sector = 150°

Area of sector = area of circle (150/360)

 = 113.04 *(150/360)

 = 47.1 cm²

<u>To find the area of triangle</u>

Area of this triangle = (1/2)r²Sinθ

 = (1/2) * 6² * Sin(150)

 = 9 cm²

<u>To find  the area of the lighter shaded region</u>

Area of lighter shaded region = Area of sector - area of triangle

 = 47.1 - 9

 = 38.1 cm²

BlackZzzverrR [31]

Answer:

$875.39

Step-by-step explanation:

1) Divide the tax rate (6.500%) by 100 to get a decimal rate of 0.06500.

2) Multiply the purchase price ($821.95) by the 0.06500 to get a sales tax amount of $53.43.

3) Add the $53.43 sales tax to the $821.95 price to get a total of $875.38.

4) Round $875.38

notka56 [123]

Answer:

For every 9 girls there are 8 boys!

Step-by-step explanation:

So for the box under 9 there would be 8 and the next box on top of 16 would be 18 because 2*8 is 16 and 2*9 is 18.

A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test
SSSSS [86.1K]

A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test statistic for this test is a "F-statistics."

<h3>What is F-statistics?</h3>

An F statistic is a value obtained after performing an ANOVA test or even a regression analysis to determine whether the means of two populations differ significantly.

Some key features regarding the F-statistics are-

  • It is comparable to a T statistic from the a T-Test; a T-test would then inform you when a single result is statistically significant, whereas a F test would then tell you if a set of variables is statistically significant.
  • When determining whether your total results are significant, you must use the F statistic in conjunction with the p value. Why?
  • A significant result does not imply that all of your variables have been significant.
  • The statistic is simply comparing the cumulative influence of all the variables.
