In what percent of the months does
she write MORE than 3 articles?
%
Answers
Answer: 75%
Step-by-step explanation:
9/12 months are number larger than three. 9/12 simplified is 3/4 and 3/4 is 75%
There are 12 months. She wrote more than three articles 9 out of the 12 months. To find the percentage you need to divide. 9 divided by 12 is .75, to convert a decimal to a percent you have to move the decimal 2 places to the right. Therefore, you get 75%

identify hypotheses.Write the null and alternative hypotheses in words and then symbols foreach of the following situations.(a) A tutoring company would like to understand if most students tend to improve their grades(or not) after they use their services. They sample 200 of the students who used their servicein the past year and ask them if their grades have improved or declined from the previousyear.(b) Employers at a firm are worried about the effect of March Madness, a basketball championship held each spring in the US, on employee productivity. They estimate that on a regular businessday employees spend on average 15 minutes of company time checking personal email, makingpersonal phone calls, etc. They also collect data on how much company time employees spendon such non-business activities during March Madness. They want to determine if these dataprovide convincing evidence that employee productivity changed during March Madness.(c) Since 2008, chain restaurants in California have been required to display calorie counts ofeach menu item. Prior to menus displaying calorie counts, the average calorie intake of dinersat a restaurant was 1100 calories. After calorie counts started to be displayed on menus,a nutritionist collected data on the number of calories consumed at this restaurant from arandom sample of diners. Do these data provide convincing evidence of a difference in theaverage calorie intake of a diners at this restaurant
Answers
Answer:
H0 : μ = 0 ; H1 : μ > 0 ;
H0 : μ = 15 ; H1 : μ ≠ 15
H0 : μ = 1100 ; H1 : μ ≠ 1100
Step-by-step explanation:
Null hypothesis H0 : mean grade of student after they use service of tutoring company is the same.
H0 : μ = 0
Alternative hypothesis H1 : mean grade of student after using service of the tutoring company increases
H1 : μ > 0
2.)
Null hypothesis H0 : Average or mean company time spent checking personal is 15 minutes
H0 : μ = 15
Alternative hypothesis H1 : Average or mean company time spent checking personal mail is not equal to 15 minutes
H1 : μ ≠ 15
C.)
Null hypothesis H0 : Average calorie intake of diner at restaurant.
H0 : μ = 1100
Alternative hypothesis H1 : There is a difference in average calorie intake of diner at restaurant.
H1 : μ ≠ 1100

6- A restaurant charges $48 on a food bill. The tax on the food bill is 9%.
If you give the waiter a 20% tip, what is the total cost of the bill?
Answers
Answer:
$61.92
Step-by-step explanation:
Given data
Charge for food= $48
Tax= 9%
Tip=20%
Let us find the amount of the tax and the tip
Tax
=9/100*48
=0.09*48
=$4.32
Tip
=20/100*48
=0.2*48
=$9.6
Hence the total amount paid is
=48+4.32+9.6
=$61.92
A line that includes the point (7,0) has a slope of 1. What is its equation in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answers
Answer:
[tex]y = x-7[/tex]
Step-by-step explanation:
To write the equation of the line in slope-intercept form, use the slope-intercept formula, [tex]y = mx +b[/tex]. Find real values for the [tex]m[/tex] and [tex]b[/tex] and substitute them into the formula.
1) We know that [tex]m[/tex] represents the slope, so substitute 1 in its place. However, we still need to find [tex]b[/tex], or the y-intercept. So, along with substituting that 1 in for [tex]m[/tex], substitute the x and y values for (7,0) for the x and y in the formula as well. Then, isolate [tex]b[/tex] to find its value:
[tex]y = mx + b\\0 = (1)(7)+b\\0 = 7 + b\\-7 = b[/tex]
So, [tex]b[/tex] = -7.
2) Now, just substitute the found values for [tex]m[/tex] and [tex]b[/tex] into the slope-intercept formula. Remember that the slope is [tex]m[/tex], so substitute 1 in, and [tex]b[/tex] is -7, so substitute -7 in its place as well. This gives the following equation in slope-intercept form:
[tex]y = 1x -7[/tex] or [tex]y = x-7[/tex]
