Can you help me? - a Statistic question

If I have a TS of 0.45 in a left tailed test, Is the P Value is about 67.2 right?-To answer this question you need to provide the test statistics distribution. What 1-tailed test are you conducting? H

Quick question (1/2)^n = (2)^-n or 2^(n-1)

Just a little hazy on those properties... any help is appreciated :)-(2)^-n You can think about it this way:(1/2)^n is the same as (1^n)/(2^n) but since 1 to any power is still 1 you can ignore the

If 60 cats can catch 60 mice in 60 minutes, how many mice can 30 cats catch in 30 minutes

1 cat catches 1 mouse per hour on average, so i think 15.-assuming its the same cats and mice,the rate is 1 mouse per 1 cat in 1 min. so, 30 is the ans.-probably 30, since everything is cut in half o

Which factor can you cancel from the numerator and denominator to simplify 8-2x/3x-12

[Hint: (a−x) = − (x − a)]-You can cancel (x - 4). -2(x - 4) / 3(x - 4) = -2/3-Meli 409 has it correct. The key to the answer lies in the multiplication tables by recognizing that 2 is a factor of 8 a

Please helpp Solve each polynomial equation by factoring

x^3-3x^2+16x-48=0 x^3-5x^2-3x+15=0 show all work explain it thankss:)-1. x^3-3x^2+16x-48 Factor GCF from each group of two terms: x^2(x - 3) + 16(x - 3) Factor out (x - 3) :(x^2 + 16)(x - 3) (x^2 +

Find the general solution of the equation

2[sin(x)]^3=sinx thx :)-... 2sin^3(x) = sin(x) or sin(x) ( 2 sin^2(x) - 1 ) = 0 or sin(x) = 0 .... → x = nπ or sin(x) = 1/√2 → x = { π/4 (8n+1), π/4 (8n+3) }-2[sin(x)]^3/sinx=1 2(sinx)^2=1 (sinx)^2

PLEASE help! Area of a regular decagon!

Ok so I have to find the area of a regular(congruental sided) decagon and I know that the perimeter is 240 and each side is 24. I looked online and found out that the formula is 1/2(ap), so I guess th

Change the order of integration

change the order of integration, make the drawing area of integration (integral from 0 to 3 dx ) integral from (x^2) to (x+6)f(x,y)dy-The given region is between y = x^2 to y = x+6 for x in [0, 3]. T

EASY GEOMETRY I CAN'T FOR SOME REASON FIGURE OUT! PLEASE HELP ME I'M FREAKING OUT!

a circle has two segments, part of one of them is y+1, the other part is y+9 part of the other segment is 7, the other part is 12 what is the value of y?-the value of y is 5 :) because 9+5=14 and 5+1=

Trigonometry question anyone?????????????

Write the general solution for 2 tan x + √ (12) = 0. Determine the general solution to sin (x/2) = √(3) /2.Use radian measure in your solution-tan x = - √3 ---> x = 2π/3 + nπ sin ( x / 2 ) = √3 / 2

What is the product of 5 √25d • 2d √3

5 √25d • 2d √3=25d x 2d√3=50d²√3-product of 5 √25d • 2d √3 or, 5*5 2d^2root over 3 or,sqrt3* 50d^2is the answer-((5√25d)(2d√3)2d√3) (5*5√d)(2d√3) 25√d)(2d√3) 50d(√3d)-5 √25d • 2d √3 = 5 × (+/- 5) × 2

Can somebody help me solving this question

Find the term in x^3 in the expansion of (1+5x)^2(1-2x)^6-For a binomial expansion (a + b)^n: --There are n + 1 terms --The sum of the exponents in each term is n --The exponent of the b term is one

Please help me with this Question
