You use software to carry out a test of significance. The program tells you that the P-value is P = 0.008. This result is

devlian [24]

The p-value determines if the result of the test is significant or not. Very small values of p, show that the result is significant.

Based on p-value, the null hypothesis is rejected based on following criteria:

1) P-value ≤ Significance Level (α)
In this case, the null hypothesis is rejected. This shows the results do not just occur by chance and are significant.

2) P-value > Significance Level (α)
In this case, we fail to reject the null hypothesis. This shows the results are not significant.

p-value of 0.008 is very small value. Usually the α value is set to be 0.01 or 0.05, but it may vary depending on the problem we are dealing with. So such a small p-value signifies that the result is significant.

Sarah mixes 2/3 cup of low fat milk and 1/2 cup of skim milk and the mixture has 111 calories. She knows that if she mixes one c

pickupchik [31]

The calories in a cup of low fat milk is 102 calories and the calories in a cup of milk in skim 86 calories .

<h3>What are the two simultaneous equations that can be sued to represent this question?</h3>

2/3l + 1/2s = 111

4l + 3s = 666 equation 1

l + s = 188 equation 2

Where:

l = calories in the low fat milk

s = calories in the skim milk

<h3>What is the calories in the skim milk?</h3>

Multiply equation 2 by 4

4l + 4s = 752 equation 3

Subtract equation 1 from 3

s = 86

<h3>What is the calories in the low fat milk?</h3>

Substitute for s in equation 2

l + 86 = 188

l = 188 - 86

l = 102

Find the 110th term for the following sequence 4, 9, 14, 19, 24,..

Vinil7 [7]

Answer:

549

Step-by-step explanation:

Given :-

A sequence 4 , 9 , 14 , ...

And we need to find out the 110th term . the given sequence is in Arithmetic progression . So the common difference is 9 -4 = 5 . Now using the formula to find out the nth term of AP ,

Using formula :-

$:\implies$ T_n = a + ( n -1)d

$:\implies$ T_n = 4 + (110-1)5

$:\implies$ T_110 = 4 + 109*5

$:\implies$ T_110 = 4 + 545

$:\implies$ T_110 = 549 .

Hence the 110 th term is 549 .
