On a print-out of these slope fields, sketch for each three solution curves to the differential equations that generated them. Then complete the following statements: For the slope field in figure 1. a solution passing through the point (0.-1) has slope. For the slope field in figure 1. a solution passing through the point (-2.2) has slope. For the slope field in figure 2. a solution passing through the point (1.-3) has slope For the slope field in figure 2. a solution passing through the point (0.4) has a slope.
Therefore solution to this question is slope at (0,-1) is negative at (-2,2) is negative at (1,-3) is negative & (0,4) is also negative.
What is slope field?A slope field, which displays the slope of a differential equation along specific vertical and horizontal axes of the x-y plane, can be used to estimate the tangent slope at a particular point on a curve, where the curve is one possible solution to the differential equation.
Here,
For figure 1 slope field=
[tex]\frac{dy}{dx}=\frac{-17x-2y}{y}[/tex]
For figure 2 slope field=
[tex]\frac{dy}{dx} = xy-3\\[/tex]
For figure 1 a solution passing through the point (0,-1)
therefore,
slope=
[tex]\frac{dy}{dx}=\frac{-17x-2y}{y}\\\frac{dy}{dx}=\frac{-17(0)-2(-1)}{-1}=-2[/tex]
so slope comes out to be negative
For figure 1 a solution passing through the point (-2,2)
[tex]\frac{dy}{dx}=\frac{-17x-2y}{y}\\\frac{dy}{dx}=\frac{-17(-2)-2(2)}{-1}=-30[/tex]
so slope comes out to be negative
For the slope field in figure 2. a solution passing through the point (1.-3)
[tex]\frac{dy}{dx} = xy-3\\\\\frac{dy}{dx}=(1*-3)-3=-6[/tex]
so slope comes out to be negative
[tex]\frac{dy}{dx} = xy-3\\\\\frac{dy}{dx}=(0*4)-3=-3[/tex]
so slope comes out to be negative.
Therefore solution to this question is slope at (0,-1) is negative at (-2,2) is negative at (1,-3) is negative & (0,4) is also negative.

question the range for a list of measurements equals the greatest measurement minus the least measurement. the two lists of measurements, x and y , combined consist of 30 measurements with a range of 25. what is the range for the measurements in list x ? (1) the range for the 12 measurements in list y is 20. (2) list x consists of 18 measurements.
The statements are insufficient to answer the question.
What is measurement?
Measurement is the quantification of an object's or event's attributes for comparison with other objects or events. Measurement, in other words, is the process of determining how large or small a physical quantity is in comparison to a basic reference quantity of the same kind.
So we are given 2 lists, x and y and we are given the
1. The total number of measurements is 30. x(n) + y(n) = 30.
2. Largest measurement - Smallest Measurement = 25
But we are not told the number of measurements in either x or y. We also don't know whether the largest of smallest measurement of the combined range belongs to x or y.
We need to find the largest measurement of x and the smallest measurement of x for our answer.
1)The range for the 12 measurements in list y is 20.
Okay so we know that y has 12 measurements, therefore x has 18. And we know the y(largest) - y(smallest) = 20 INSUFFICIENT
2) List x consists of 18 measurements.
We are told that x consists of 18 elements. We already figured this out in Statement 1 as well. It again does not tell us anything further. INSUFFICIENT DATA

g assuming a linear relationship between x and y, the larger r-square value is, the larger the absolute value of the coefficient of correlation
In the domain of finance, an R-Squared value above 0.7 is typically seen as indicating a high level of correlation, whereas one below 0.4 indicates a low level of correlation.
What is correlation?A statistical measure known as correlation expresses how closely two variables are related linearly (meaning they change together at a constant rate). It's a typical technique for describing straightforward connections without explicitly stating cause and consequence.
The strength of the association is measured by the sample correlation coefficient, or r. The statistical significance of correlations is also examined.
For describing straightforward links between data, correlations are helpful. Consider a dataset of campgrounds in a park in the mountains as an illustration. You're interested in finding out if the height of the campsite—how high up the mountain it is—and the summer's typical high temperature are related.
Hence, In the domain of finance, an R-Squared value above 0.7 is typically seen as indicating a high level of correlation, whereas one below 0.4 indicates a low level of correlation.

The odds in favor of Michael Jordan making a free throw were 21:4. Find the probability of Michael Jordan missing a free throw.
Give answer as a decimal rounded to the nearest hundredth.
The probability that he will miss is 25%.
What is probability?
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.
The odds in favor of Michael Jordan making a free throw were 21:4.
Total number of throw is 21+4 = 25

170 / 2 = 85 km/hr
We know that one car is traveling 18 km/hr faster than the other car. One way we can account for this is to ± 9 km/hr to the average speed:
85 ± 9 = 94 , 76 km/hr
rate of slower car x = 84 - 9 * 2
x = 76 * 2 km/hr
= 152 km/hr
Therefore The rate of the slower car is 152 km/hr.
