The box plots show the average wind speeds, in miles per hour, for various cities in two different countries.
Box plots are graphical representations of data that summarize important features such as the center, spread, and shape of a distribution. In this case, the box plots show the average wind speeds, in miles per hour, for different cities in two different countries.
The box in the plot represents the middle 50% of the data, with the line inside the box showing the median. The whiskers extend to the minimum and maximum values of the data, excluding any outliers, which are shown as individual points outside the whiskers.
Comparing the box plots for the two countries, we can see that the average wind speeds for the cities in Country A are generally lower than those in Country B. The box in Country A is shorter and closer to the bottom of the plot, indicating less variability in the data. Meanwhile, the box in Country B is taller and more spread out, suggesting a wider range of wind speeds across the cities.

help plss 1/3(3m+6)-2(2m+6)
Answer:
To simplify the expression, you can start by using the distributive property of multiplication over addition/subtraction and then combine like terms.
1/3(3m+6) - 2(2m+6)
= 1/33m + 1/36 - 22m - 26 (distribute the multiplication)
= m + 2 - 4m - 12 (simplify by multiplying and adding the terms)
= -3m - 10 (combine like terms)
Therefore, 1/3(3m+6)-2(2m+6) simplifies to -3m - 10.

Christine swam 2 kilometers against the current in the same amount of time it took her to swim 8 kilometers with the current. The rate of the current was 3 kilometers per hour. How fast would Christine swim if there were no current?
If the rate of the current was 3 kilometers per hour, Christine's speed in still water is 5 kilometers per hour.
Let's start by assuming that Christine's speed in still water is x kilometers per hour. We know that the current is flowing at a rate of 3 kilometers per hour.
When Christine is swimming against the current, her effective speed is reduced by the speed of the current, so her speed is (x-3) kilometers per hour. If it takes her the same amount of time to swim 2 kilometers against the current as it does to swim 8 kilometers with the current, we can set up an equation:
time to swim 2 km against current = time to swim 8 km with current
We can use the formula distance = speed x time to express the distance that Christine covers in each scenario. The distance she covers against the current is 2 kilometers, and the distance she covers with the current is 8 kilometers. So our equation becomes:
2 / (x - 3) = 8 / (x + 3)
To solve for x, we can cross-multiply and simplify:
2(x + 3) = 8(x - 3)
2x + 6 = 8x - 24
6x = 30
x = 5

Line A has equation y = -4x + 1 and line B contains the points (-2,1) and (1,-11). Select any statement(s) below that are true.
Line B has a slope of -5.
Line A has a slope of -4.
Line A and line B have the same slope.
Line B has a flatter slope than line A.
Line A has a flatter slope than line B.
Answer:
Line A has a slope of -4
Line A and line B have the same slope
Step-by-step explanation:
Line A is in the slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. As we can see, -4 is m in line A so -4 is the slope of line A.
If we have two points on a line, we can find the slope using the slope formula
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], where x1 and y1 are one of the points and x2 and y2 come from the other point.
Thus, if we allow (-2, 1) to be x1 and y1 and (1, -11) to be x2 and y2,
[tex]m=\frac{-11-1}{1-(-2)}\\ m=-4[/tex]
Since the slope of Line B is -4, it has the same slope as line A
The reading on the thermometer is -10 degrees celsius and the temperature drops with 10 degrees celsius what will the new reading be
The thermometer reads -10 degrees Celsius, and the temperature drops by 10 degrees Celsius. As a result, the new thermometer reading will be -20 degrees Celsius.
If the temperature drops by 10 degrees Celsius and the initial reading on the thermometer is -10 degrees Celsius, we can calculate the new reading as follows:
New reading = Initial reading - Temperature drop
New reading = (-10) - 10
New reading = -20
Therefore, the new reading on the thermometer will be -20 degrees Celsius.
When we say the temperature drops by 10 degrees Celsius, we mean that the temperature decreases by 10 degrees Celsius from its initial value. In this case, the initial value is -10 degrees Celsius.
So, if the temperature drops by 10 degrees Celsius, we need to subtract 10 from the initial value to get the new temperature reading. This is because a decrease in temperature means the temperature value becomes lower.
The resulting new reading of -20 degrees Celsius is 10 degrees Celsius lower than the initial reading of -10 degrees Celsius. It indicates that the temperature has decreased further, and it is now even colder than before.

A certain baseball pitcher gives up a base hit (on average) once every 15 pitches. in a particular game he threw 120 pitches. find the probability he gave up at MOST 2 base hits.
The probability that the pitcher gave up at most 2 base hits in the game is approximately 0.53.
What is probability?
Probability is a branch of mathematics in which the chances of experiments occurring are calculated.
Let X be the number of base hits given up in 120 pitches. Then X follows a binomial distribution with parameters n = 120 (number of trials) and p = 1/15 (probability of success in each trial).
The probability of giving up at most 2 base hits can be calculated as follows:
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)
Using the binomial probability formula, we have:
P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)
where (n choose k) is the binomial coefficient, which gives the number of ways to choose k successes from n trials.
Plugging in the values, we get:
P(X = 0) = (120 choose 0) * (1/15)^0 * (14/15)^120 ≈ 0.028
P(X = 1) = (120 choose 1) * (1/15)^1 * (14/15)^119 ≈ 0.17
P(X = 2) = (120 choose 2) * (1/15)^2 * (14/15)^118 ≈ 0.33
Therefore,
P(X ≤ 2) = 0.028 + 0.17 + 0.33 ≈ 0.53

Step-by-step explanation:
An explicit formula for a sequence allows you to find the nth term of the sequence.
A recursive formula for a sequence allows you to find the nth term of the sequence provided you know the value of the previous term in the sequence.
Given recursive rule:
[tex]\begin{cases}a_{n+1}=a_n+7\\a_1=-22\end{cases}[/tex]
From the given recursive rule, we can see that each term is 7 more than the previous term. Therefore, the common difference between terms is d = 7.
Explicit formula[tex]a_n = a_1 + (n - 1)d[/tex]
Input the values of a₁ and d into the explicit formula:
[tex]\implies a_n=-22+(n-1) \cdot 7[/tex]

I bought a new car to transport my kids and all their stuff. The value of the car y (in thousands of dollars) can be represented by the model y=41(0. 92)^t
, where t is the number of years since I purchased the car. Which value in the equation represents the decay factor?
The decay factor in the equation y=41(0.92)^t is the value of (0.92) raised to the power of t.
In this case, the base of the exponential function is 0.92, which is less than 1. This means that as t increases, the value of (0.92)^t decreases exponentially, leading to a decay in the value of y. The decay factor is the factor by which the value of y decreases each year.
In this case, the decay factor is 0.92, which means that the value of the car decreases by 8% each year. This is because (0.92) x 100% = 92%, so the value of the car decreases to 92% of its previous value each year.

The process of counting from 0 to 10 using 4 fours and the four basic operations can be explained mathematically by the following equation: 4 + 4 - 4 x 4 / 4 + 4 + 4 - 4 = 12
The result when using 4 fours and the four basic operations (addition, subtraction, multiplication, division) to count from 0 to 10 is as follows:
0 = 4 ,1 = 4 + 4 = 8 ,2 = 8 - 4 = 4 ,3 = 4 x 4 = 16 ,4 = 16 / 4 = 4 ,5 = 4 + 4 + 4 = 12 ,6 = 12 - 4 = 8 ,7 = 8 x 4 = 32, 8 = 32 / 4 = 8 ,9 = 8 + 4 + 4 = 16 ,10 = 16 - 4 = 12 .The process of counting from 0 to 10 using 4 fours and the four basic operations can be explained mathematically by the following equation: 4 + 4 - 4 x 4 / 4 + 4 + 4 - 4 = 12. This equation is made up of four parts, each representing an operation in the correct order. The first part of the equation is 4 + 4 = 8, which adds the two fours together to get 8. The second part of the equation is 8 - 4 = 4, which subtracts the four from the 8 to get 4. The third part of the equation is 4 x 4 = 16, which multiplies the two fours together to get 16. The fourth part of the equation is 16 / 4 = 4, which divides the 16 by 4 to get 4. The fifth part of the equation is 4 + 4 + 4 = 12, which adds the three fours together to get 12. The sixth part of the equation is 12 - 4 = 8, which subtracts the four from the 12 to get 8. Finally, the last part of the equation is 8 + 4 + 4 = 16, which adds the three fours together to get 16.

the ratio of the sides of a triangle is 3:10:7. What is the length of the shorest side?
Answer:
The length of the shortest side is 3 units.
Step-by-step explanation:
Let's assume that the shortest side has a length of 3x, where x is a constant.
Then, the other sides would have lengths of 10x and 7x, respectively.
To check if this is a valid triangle, we need to make sure that the sum of the lengths of any two sides is greater than the length of the third side:
3x + 10x > 7x (sum of shortest and middle side is greater than longest side)
3x + 7x > 10x (sum of shortest and longest side is greater than middle side)
10x + 7x > 3x (sum of middle and longest side is greater than shortest side)
Simplifying these inequalities, we get:
13x > 7x
10x > 3x
17x > 0
All of these inequalities are true if x > 0, so our assumption is valid.
Therefore, the length of the shortest side is 3x. To find the value of x, we can set up the following equation based on the given ratio:
3x : 10x : 7x = 3 : 10 : 7
Simplifying this equation by dividing all sides by x, we get:
3 : 10 : 7 = 3 : 10 : 7
This is true, so any value of x will satisfy the given ratio.
However, to find the length of the shortest side, we can simply substitute x = 1 into our assumption:
Shortest side = 3x = 3(1) = 3
Therefore, the length of the shortest side is 3 units.
