In a study of the accuracy of fast food drive-through orders, one restaurant had 36 orders that were not accurate among 322 orders observed. Use a 0.01 significance level to test the claim that the rate of inaccurate orders is equal to 10%. Does the accuracy rate appear to be acceptable?

Step-by-step explanation:

Given that in a study of the accuracy of fast food drive-through orders, one restaurant had 36 orders that were not accurate among 322 orders observed.

Sample proportion = 36/322= 0.112

Hypotheses would be:

(two tailed test at 1% significance level)

p difference = 0.012

Std error =

Test statistic =

p value = 0.48

since p >0.01 we accept null hypothesis

The accuracy rate appears to be acceptable as only 10% are not accurate.

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
