If the smaller of two numbers is one-half of the larger number and the sum of the two numbers is 81 , find the numbers.
zavuch27 [327]
Let smaller number be x/2 and the larger number x.

x/2 + x = 81
x/2 + x = 3x/2
3x/2 = 81
3x = 162
x= 54

The smaller number is 54/2= 27 and the larger number is 54.

Which table shows a proportional relationship between x and y?
Vilka [71]

Answer:

Table 3

Step-by-step explanation:

In a proportional relationship there must be a constant rate of change.

The first table:

6-5 / 9-7 = 1/2

5-3 / 7-4 = 2/3

These are not equal so it is not proportional.

The second table:

10-8 / 150-120 =2/30

8-5 / 120-75 = 3/45

These are not equal so it is not proportional

The third table:

10-8 / 12-10 =2/2 = 1

8-6 / 10-8 =2/2 = 1

These are equal so this table is proportional.

A local chess club claims that the length of time to play a game has a standard deviation of more than 13 minutes. Write sentenc
tatyana61 [14]

Answer:

Step-by-step explanation:

A type I error occurs when the researcher rejects the null hypothesis when it is actually true.

A type II error occurs when the research fails to reject the null hypothesis when it is not true.

In this case study,

The null hypothesis is the standard deviation is less that or equal to 13min.

The alternative hypothesis would be that the standard deviation is greater than 13mins.

A type I error would occur when having done an experiment, the researcher rejects the null hypothesis when there is enough evidence that it is actually either less or equal to 13mins

A type II error would occur when the researcher fails to reject the null hypothesis when there is enough evidence that it is actually more than 13mins.
