Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value u
Alenkasestr [34]

Answer:

The  value is  1.75 \  and  \   -1.75

Step-by-step explanation:

From the question we are told that

     The null hypothesis is  H_1 :  \mu \ne 3.24

     The level of significance is  \alpha = 0.08

From the z table  the critical value of  \alpha considering the two tails of the normal  curve( This is because this a two tailed test ) is

       z= \pm  1.75

Hence the critical value is  

       1.75 \  and  \   -1.75

Tomas bought 80 tickets for rides at an amusement park. Each ride costs 5 tickets, and Tomas has been on x rides so far. Which e
Alex Ar [27]

Answer:

Option A, C and D are correct choices.

Step-by-step explanation:

Let x be the number of rides that Tomas has been on so far. Each ride costs 5 tickets. This means that cost of x rides will be 5x.

We are told that Tomas bought 80 tickets for rides at an amusement park.

To find the number of of tickets that Tomas has left we will subtract cost of x rides from total number of tickets that Thomas bought.

We can represent this information in an expression as: 80-5x

Now let us see which of our given choices in equivalent to our expression.

A. 80-5x

Upon looking at option A we can see that it is same as our expression, therefore, option A is the correct choice.

B. 80+5x

We can see that in this expression cost of x rides in being added instead of subtraction, therefore, option B is not a correct choice.

C. 5(16-x)

Upon distributing 5 we will get,

80-5x

Now this expression is same same as our expression, therefore, option C is the correct choice.

D. -5x+80

This expression is also same as our expression as we can rearrange the terms in this expression as: 80-5x, therefore, option D is a correct choice as well.

E. 5(16+x)

Upon distributing 5 we will get,

80+5x

We can see that in this expression cost of x rides in being added instead of subtraction, therefore, option E is not a correct choice.

Bar graphs are used to compare things between different groups or to track changes over time. Bar graphs are an extremely effective visual to use in presentations and reports. They are popular because they allow the reader to recognize patterns or trends far more easily than looking at a table of numerical data. Further, Bar graphs are an effective way to compare items between different groups.
