Answer:
every difference x-y is the same for related pairs of x and y
Answer:
Option b
Step-by-step explanation:
Given that For a particular course, the pass rate for the 16-week format is 59%. A team of faculty examine student data from 40 randomly selected accelerated classes and determine that the pass rate is 78%.
we have to find whether taking a class in a short-term format (8 weeks instead of 16 weeks) increase a student’s likelihood of passing the course
Since pass rate for 16 weeks is 59% we check whether for 8 weeks is more than this.
So correct null and alternative hypotheses for this research question
would be:
b.H0: p = 0.59; Ha: p > 0.59
Option b is right.
Y = 3.50x
245 = 3.50x
x = 245/3.5
x = 70 coffee mugs
315 = 3.50x
x = 315/3.5
x = 90 coffee mugs
Ronny needs to sell 90 coffee mugs to reach his sales goal. However, he already sold 70 coffee mugs, so he needs to sell an additional 20 coffee mugs to reach 90 coffee mugs and reach his $315 sales goal.
Answer:
20 days?

3 times a day is 15 and 300 ÷ 15 = 20
Rate is a ratio of different units ( a quantity times a quantity), such as miles per hour.
Unit rate is a rate with a denominator of 1.
To find unit rate, divide the total cost by the quantity:
0.89 / 16 = 0.0556 per ounce.
