Sally is $3.95 in dimes and quarters that shows the total 23 coins how many times does she have and how many quarters does she h

UkoKoshka [18]

Make a system of equations:

0.10x + 0.25y = 3.95
x + y = 23

x + y = 23

Subtract 'y' to both sides:

x = -y + 23

Plug in -y + 23 for 'x' in the first equation:

0.10(-y + 23) + 0.25y = 3.95

Distribute 0.10:

-0.10y + 2.3 + 0.25y = 3.95

Subtract 2.3 to both sides:

-0.10y + 0.25y = 1.65

Combine like terms:

0.15y = 1.65

Divide 0.15 to both sides:

y = 11

Plug this into any of the two equations to find 'x':

x + y = 23

x + 11 = 23

Subtract 11 to both sides:

x = 12

So Sally has 11 dimes and 12 quarters.

Determine whether the following results appear to have statistical significance, and also determine whether the results have pr

MA_775_DIABLO [31]

Considering the p-value of the test, it is found that the result has neither statistical nor practical significance, as it does not give sufficient evidence that the IQ is increases by 10 to 20 points.

<h3>What is the relation between the p-value and the conclusion of the test hypothesis?</h3>

Depends on if the p-value is less or more than the significance level:

If it is more, the null hypothesis is not rejected.

If it is less, it is rejected.

In this problem, the p-value is of 0.28, which is greater than 0.05, hence there is not enough evidence that the IQ increase is as stated, meaning that the result has neither statistical nor practical significance.
