Answer:0.05

Step-by-step explanation: p-value also known as probability value is the probability of obtaining the same result as the result obtained during the testing of the hypothesis as long as the hypothesis is correct.

The smaller the p-value the higher the Significant differences between the test hypothesis and the research outcome,which possibly will mean that the test hypothesis is wrong or has some short comings. The p-value is usually denoted as 0.01,0.05,0.001, or 0.005.

With a p-value of around 0.05 or

less than 0.05 means their is a significant difference between the test hypothesis and the test results so the test hypothesis should be rejected.

Kenny is 8 years older than Andrew. Tim is 3 times
9966 [12]

Answer:

Kenny is 18 years old Andrew is 10 years old Tim is 30 years old and Cameron is  5 years old

Step-by-step explanation:

Let a be Kenny's age , b be Andrew's age , c be Tim's age , d be Cameron's age

( b < a , b<c , d<b)

Kenny is 8 years older than Andrewn = > a = b + 8 (1)

Tim is 3 times  as old as Andrew => c = 3 . b (2)

Cameron is 5 years younger than  Andrew => d = b-5 (3)

The combined age of the four is 63 => a+b+c+d = 63 (4)

(1),(2),(3),(4) => b+8 + b + 3b + b-5 = 63 <=> 6b + 3 = 63 <=> b = 10

=> a= 10+8 =18, c = 3 . 10 = 30, d= 5

Consider the equation 9x+3=x−1. Squaring the left side and simplifying results in​ _______. Squaring the right side and simplify
bixtya [17]

Answer:

The first blank is 81x^{2}+9=x-1

The second blank is 9x+3=x^2-1

Step-by-step explanation:

For the first part, you must set up the equation (9x+3)^2       then you must multiply the exponent to the inside exponents 9^{2} x^{2}+3^{2} next, simplify.

81x^{2}+9=x-1

For part two, set up equation. x^{2} -1^{2} Then simplify 9x+3= x^{2} -1
