Answer:
About 276,500 country A students studied abroad during the 2012-2013 school year.
Step-by-step explanation:
Given that in the 2012-2013 school year, approximately 790,000 foreign students studied in country A, and the number of country A students who studied abroad that same year was about seven-twentieths of the number of foreign students who studied in the country A, to find the number of country A students who studied abroad during the 2012-2013 school year, the following calculation must be performed:
790,000 x (7/20) = X
790,000 x 0.35 = X
276,500 = X
Therefore, about 276,500 country A students studied abroad during the 2012-2013 school year.

In this equation you are trying to find O. We also know that OA = OB.
2x + 9 = 27 - x
2x = 18 - x (subtracted 9 from each side)
3x = 18 (added 1x to each side)
x = 6 (divided both sides by 3, to find x)

A flowerpot has a circular base with a diameter of 27 centimeters. Find the circumference of the base of the flowerpot. Round to the nearest tenth.
How would you go about solving this?
The circumference of the base of the flowerpot is 84.8cm
What is circumference of a circle?Circumference of a circle can be described as the length or distance of a circle.
The formular that can be used to calculate the circumference of a circle is
= 2πr
Radius= diameter/2
= 27/2
= 13.5
The circumference can be calculated as follows
= 2πr
= 2 × 3.142 × 13.5
= 84.83
≅ 84.8 (to the nearest tenth)
Hence the circumference of the base of the flower pot is 84.8 cm

Step-by-step explanation:
If the amount of time to prepare and deliver a pizza from MOD PIZZA is normally distributed with a mean of 20 minutes and standard deviation of 5 minutes.
Determine the percent of pizzas that were prepared and delivered:
(a) Between 20 and 25 minutes (b) In less than 18 minutes
( c ) If MOD PIZZA advertises that the Pizza is free if it takes more than 30 minutes to deliver, what percent of the pizza will be free?
I need to answer a,b and c - it is not mutiple choice. I also need to show all relevant steps and plus I really want to understand how to do this! I am completely stuck on this one and its due tonight. Please help!! :) Ill give badges, brainliest, thanks, all of that for whoever can help me!
Using the normal distribution, we have that:
a) 34.13% of pizzas were prepared and delivered between 20 and 25 minutes.
b) 34.46% of pizzas were prepared and delivered in less than 18 minutes.
c) 2.28% of the pizza will be free.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 20, \sigma = 5[/tex]
For item a, the probability is the p-value of Z when X = 25 subtracted by the p-value of Z when X = 20, hence:
X = 25:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{25 - 20}{5}[/tex]
Z = 1
Z = 1 has a p-value of 0.8413.
X = 20:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{20 - 20}{5}[/tex]
Z = 0
Z = 0 has a p-value of 0.5.
0.8413 - 0.5 = 0.3413.
Hence 34.13% of pizzas were prepared and delivered between 20 and 25 minutes.
For item b, the probability is the p-value of Z when X = 18, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{18 - 20}{5}[/tex]
Z = -0.4
Z = -0.4 has a p-value of 0.3446.
34.46% of pizzas were prepared and delivered in less than 18 minutes.
For item c, the proportion is one subtracted by the p-value of Z when X = 30, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{30 - 20}{5}[/tex]
Z = 2
Z = 2 has a p-value of 0.9772.
1 - 0.9772 = 0.0228, hence 2.28% of the pizza will be free.
