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.

which plot would you use to plot prices of airbnb rentals as function of room type? group of answer choices boxplot scatter plot barplot histogram
A scatter plot would be the best type of plot to use to show the relationship between the price of Airbnb rentals and the room type.
A scatter plot shows the relationship between two variables by plotting each data point as a dot on the graph. In this case, the room type would be plotted on one axis and the price on the other axis, allowing you to see the distribution of prices for each room type.
By plotting the data in this way, you can see how one variable is related to another, and identify any patterns or trends in the data. This type of plot is particularly useful for exploring the relationship between two continuous variables.

3.3 3.3 pounds of apples at the total cost of $18.15 $ 18.15 . if she purchases 7.9 7.9 pounds of apples at this store, how much would it cost?
The unit cost of apples is found to be $5.5 per pound. So the cost of 7.9 pounds of apple will be 43.45.
Here we have to calculate the value of a pound of apple from the given data, and then should multiply the unit value to find the cost of the given weight.
Weight of apple that was purchased = 3.3 lbs.
Cost of 3.3 lbs. of apples = 18.15
Cost of a pound of apple = Cost of apples purchased/ weight of apples purchased
= 18.15/3.3 = 5.5.
So each pound of apple will cost $5.50.
Weight of apple to be purchased = 7.9 lbs.
Cost of the apples = Weight of apples × unit price
= 7.9 × 5.50 = 43.45.
So the cost of 7.9 pounds of apple will be $43.45.

What quantity of 64% chlorine solution must be mixed with a 29% chlorine solution to produce 5530 mL of 30% solution?
Answer:
you need 221.2 ml of the 64% and 5308.8ml of the 29%
Step-by-step explanation:
the formula is (% x v)=(% * v)+(% * v)
so
(0.3 * 5530)=(0.64 * x)+(0.29 * (5530-x))
simplify
1,659= 0.64x + 1,603.7 - 0.29x
1,659=0.35x + 1,603.7
subtract 1603.7 from both sides
55.3=0.25x
divide 0.25 from both sides
221.2=x
subtract
5530-221.2
how many strawberries should be picked so that the probability of having exactly 2 rotten strawberries among them equals 2/35
The final answer will depend on the specific value of p.
Let's say we need to choose a number of strawberries. Then, using the binomial distribution formula, it is possible to determine the likelihood that there will be exactly 2 rotting strawberries among them:
P(exactly two spoiled strawberries) i= (n choose 2) * p^2 * (1-p)^(n-2)
where p is the probability of each strawberry being rotten.
By setting this to 2/35 and figuring out n, we get at:
2/35 = (n choose 2) * p^2 * (1-p)^(n-2)
2/35 = (n choose 2) * p^2 * (1-p)^(n-2)
(2/35) / p^2 = (n choose 2) * (1-p)^(n-2)
It should be noted that p's value is unknown and would need to be determined by estimation or historical data. The final answer will depend on the specific value of p.

Answer: The value of x from the diagram is 50 degrees.
Vertical angles are angles that meets at a point of intersection. From the given diagram 150 and 50+2x are vertical angles showing that they are equal to each other so:
50 + 2x = 150
2x = 150 - 50
2x = 100
Divide both sides by 2
2x/2 = 100/2
x = 50
Therefore the value of x from the diagram is 50 degrees.

On the off chance that the quantity of duplicates sold in the main month of delivery is 38,900 and addresses 8.1% of the absolute number of duplicates offered to date, then, at that point, we can utilize this data to appraise the all out number of duplicates offered to date.

When a relation is displayed in each table row represents an ordered pair with the x column representing the input values and the y column representing the output values.
True or False?
True.
In a relation, each row of a table represents an ordered pair where the x-value is in the left column (also called the domain) and the y-value is in the right column (also called the range or codomain). The x-values represent the inputs to the relation, and the y-values represent the corresponding outputs.
Relation Table RepresentationA relation is a set of ordered pairs, where the first element of each pair comes from a set called the domain and the second element comes from a set called the range or codomain. In a table representing a relation, each row represents an ordered pair where the first element (the x-value) is from the domain and the second element (the y-value) is from the range or codomain.
For example, consider the relation R = {(1, 3), (2, 5), (3, 7)}. In a table representing R, the x column represents the first element of each ordered pair (i.e., the domain) and the y column represents the second element of each ordered pair (i.e., the range or codomain).
The first row of the table would be (1, 3), where 1 is the input (x-value) and 3 is the output (y-value) for the relation R. The second row of the table would be (2, 5), where 2 is the input (x-value) and 5 is the output (y-value) for the relation R. And so on for the rest of the rows in the table.
Therefore, each row of a table representing a relation does indeed represent an ordered pair, where the x column represents the input values and the y column represents the output values.

What is the distance between two points of a line?The distance between two points of a line is given as:
Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
We have,
The coordinates of the endpoints are (a, b) = [tex](x_1, y_1)[/tex] and (-3, -5) = [tex](x_2, y_x)[/tex].
The distance between the two endpoints is 11 units.
Now,
Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
11 = [tex]\sqrt{(-3 - a)^2 + (-5 - b)^2}[/tex]
Squaring both sides.
11² = (-3 - a)² + (-5 - b)²
121 = (-3 - a)² + (-5 - b)²
If we take a = -3 and b = 6
121 = (-3 + 3)² + (-5 - 6)²
121 = 0 + (-11)²
121 = 121
or
If we take a = 8 and b = -5
121 = (-3 - 8)² + (-5 + 5)²
