Steve opens a bank account. The amount, in dollars, in the account x weeks after the account is opened can be modeled by functio
ANTONII [103]

The missing options are:

A.\ f(20) =5,000

B.\ f(5000) = 20

C. In the xy plane, point (20, 5,000) is on the graph y = f(x).

D. In the xy plane, point (5,000,20) is on the graph y = f(x)

Answer:

A.\ f(20) =5,000

C. In the xy plane, point (20, 5,000) is on the graph y = f(x).

Step-by-step explanation:

Given

Represent amount with y and weeks with x

So, we have:

x = 20 when y = 5000

Required

Select 2 correct options

A point on a graph can be illustrated using  (x,y)

So, when x = 20 and y = 5000 ----- given

(x,y) implies that:

(x,y) = (20,5000)

We got (20,5000) by substituting 20 for x and 5000 for y

<em />

<em>From the list of given options, the above represented of (x,y) is illustrated in option C</em>

Represent (x,y) as a function, we have:

y = f(x)

Substitute values for x and y

5000 = f(20)

Reorder

f(20) = 5000

<em></em>

The above is illustrated in option A

<em>Hence, A and C answers the question</em>

Is 4/5 greater or less than 45/100 how do you know
rusak2 [61]

Answer:

4/5 is grater than 45/100

Step-by-step explanation:

Why?

because in percentage you make the bottom # a 100 one of them already has that and when it has 100 on the bottom it tells you that the top # is the percentage so 45/100 is 45%

now to make 4/5 a percentage what times 5 = 100?

20 does

so you times the top and bottom by 20

4*20= 80

now your fraction is 80/100  (top # tells you the %)

it's 80%

80% is grater than 45%

The critical value for a hypothesis test​ _______.
Jlenok [28]

Answer:

Option C) Critical value is based on the significance level and determines the boundary for the rejection region

Step-by-step explanation:

Critical Value:

  • In hypothesis testing, a critical value is a point that is compared to the test statistic
  • It is used to determine whether to reject the null hypothesis or accept the null hypothesis.
  • If the absolute value of your test statistic is greater than the critical value,we fail to accept the null hypothesis and reject it.
  • Critical value is affected by the significance level of the testing.
  • It is the value that a test statistic must exceed in order for the the null hypothesis to be rejected.

Thus, option C) is the correct interpretation of critical values.

Option C) Critical value is based on the significance level and determines the boundary for the rejection region
