Olivia's family took a road trip to the Grand Canyon. Olivia fell asleep after they had travelled 243 miles. If the total length of the trip was 900 miles, what percentage of the total trip had they travelled when Olivia fell asleep?
The percentage of the total trip had they travelled when Olivia fell asleep is 73%.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Olivia's family took a road trip to the Grand Canyon.
Olivia fell asleep after they had travelled 243 miles.
If the total length of the trip was 900 miles,

two numbers are independently selected from the set of positive integers less than or equal to $5$. what is the probability that the sum of the two numbers is greater than their product? express your answer as a common fraction.
The probability of the sum of two integers is greater than the product is equal to 2 / 5.
Let 'A' be the set of positive integers less than or equal to 5.
A = { 1, 2, 3, 4, 5}
Sum of two numbers is greater than the product of the numbers.
1 × 1 = 1 and 1 + 1 = 2
1 × 2 = 2 and 1 + 2 = 3
1 × 3 = 3 and 1 + 3 = 4
1 × 4 = 4 and 1 + 4 = 5
1 × 5 = 5 and 1 + 5 = 6
2 × 1 = 2 and 2 + 1 = 3
3 × 1 = 3 and 3 + 1 = 4
4 × 1 = 4 and 4 + 1 = 5
5 × 1 = 5 and 5 + 1 = 6
2 × 2 = 4 and 2 + 2 = 4
Total possibilities = 5 × 5

kala's coffee shop makes a blend that is a mixture of two types of coffee. type a coffee costs kala $4.65 per pound, and type b coffee costs $5.85 per pound. this month, kala made 134 pounds of the blend, for a total cost of $717.90. how many pounds of type a coffee did she use?
Kala used 55 pounds of type A coffee and 79 pounds of type B coffee in 134 pounds of the blend for a total cost of $717.90.
Let number of pounds in coffee type A be taken as A
Let number of pounds in coffee type B be taken as B
The total number of pounds used in the blend = 134 pounds.
Therefore, A + B = 134
A = 134 – B …….. (i)
1 pound of coffee type A costs = $4.65
Therefore, A pounds of type A coffee will cost = $4.65A
1 pound of coffee type B costs = $5.85
Therefore, B pounds of type B coffee will cost = $5.85B
Total cost of both blends = $717.90
Therefore, 4.65A + 5.85B = 717.90…….(ii)
Using substitution method, substituting equation (i) in equation (ii), we get,
4.65 * (134 – B) + 5.85B = 717.90
623.1 – 4.65B + 5.85B = 717.90
623.1 + 1.2B = 717.90
1.2B = 94.8
B = 79 pounds
Therefore, A = 134 – 79 = 55 pounds
Hence, the number of pounds of coffee type A was found to be 55 pounds

The number of possible values regarding the given fraction situation of $r$ is 8.
To find the possible values of $r$ that can be approximated by [tex]$\frac{2}{7}$[/tex], we need to determine the range of values for $r$ that is closest to [tex]\frac{2}{7}$[/tex]. This can be done by finding the two closest fractions with numerator 1 or 2 to [tex]$\frac{2}{7}$[/tex] and determining the range of values for $r$ between those two fractions. The two closest fractions are [tex]$\frac{1}{3}[/tex] and[tex]\frac{2}{5}[/tex].
If $0.abcd$ is between[tex]\frac{1}{3}[/tex] and [tex]$\frac{2}{5}[/tex], it will be closest to [tex]$\frac{2}{7}$[/tex]. The decimal representation of [tex]\frac{1}{3}$[/tex] is 0.3333..., and the decimal representation of [tex]$\frac{2}{5}$[/tex] is 0.4.

on the sldt, why is a standard score of 89 considered below average if the mean is 100 with a standard deviation of 15?
A standard score of 89 is considered below average because it is 11 points lower than the mean, which is a deviation of more than 0.7 standard deviations below the mean.
A standard score of 89 is considered below average because it falls below the mean score of 100. This is because it is 11 points lower than the mean, which is a deviation of more than 0.7 standard deviations below the mean. The standard deviation is a measure of the spread of the data, where higher values indicate more spread out data. In this case, the mean score of 100 has a standard deviation of 15, which means that any score lower than 85 (100 - 15) is considered below average. A score of 89 is 11 points below the mean, which is a deviation of more than 0.7 standard deviations. This indicates that it is lower than the average score, and therefore considered below average.

The number of measurements, and the mode being the most frequently occurring value among the snowfall measurements.
The mean, median, and mode are all useful measures of central tendency when researching the amount of snowfall in Cleveland from December to February. The mean is calculated by adding up all of the snowfall measurements and dividing that by the number of measurements. For example, if there were 4 snowfall measurements of 10, 20, 30 and 40 inches, the mean would be 25 inches (10+20+30+40 / 4). The median is the middle value of the snowfall measurements when they are arranged from least to greatest. In this example, the median would be 25 inches as well. The mode is the most frequently occurring value among the snowfall measurements. In this example, the mode is also 25 inches.

In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle.
All triangles are enclosed in a single plane if all of the geometry is the Euclidean plane, however, this is no longer true in higher-dimensional Euclidean spaces.
The orthocenter of a triangle is the intersection of the lines that carry the elevations.
