Two baseball teams, the Jayhawks and the Falcons, each recorded the number of home runs hit in 1 season by every player on the t

eam. Each team then calculated the mean number of home runs and the MAD (mean absolute deviation). Team Home runs Mean MAD Jayhawks 7.8 4.1 Falcons 8.2 3.8 Which statement best describes the overlap in the distribution of the two data sets? A. The overlap is high because both means are greater than either MAD. B. The overlap is high because the difference in the means is small compared to either MAD. C. The overlap is low because the difference in the MADs is small. D. The overlap is low because the sum of the means is large compared to either MAD.

The right answer for the question that is being asked and shown above is that: "B. The overlap is high because the difference in the means is small compared to either MAD" The <span>statement that best describes the overlap in the distribution of the two data sets is that </span><span>B. The overlap is high because the difference in the means is small compared to either MAD</span>

A quadratic equation is shown below: 4x2 − 12x + 9 = 0

A)

The discriminant (radicand) is √(b^2-4ac), let us call this "d" for the discriminant.

If:

d<0, there are no real solutions (though there are two imaginary ones)

d=0, there is one real solution

d>0, there are two real solutions.

In this case, d=12^2-4(4)9

d=144-144

d=0

So there is one real solution.

B)

9x^2-30x+25=0

9x^2-15x-15x+25=0

3x(3x-5)-5(3x-5)=0

(3x-5)(3x-5)=0

(3x-5)^2=0

x=5/3

x=1 2/3

? divided by 2/3= 3/8
NeX [460]
When you divide by a fraction all you have to is multiply by the reciprocal. The reciprocal of 3/8 is 8/3. 
<span>The real problem is 2/3 TIMES 8/3. Multiply the numerators across 2 X 8 = 16. Then multiply the denominators across 3 X 3 = 9. The answer is 16/9. If you need to simplify then the answer is 1 7/9.</span>

Answer:

No

Step-by-step explanation:

x + 1 is not a factor of the polynomial because the remainder is 2 and not 0

Match the key aspect of a function's graph with its meaning
Aliun [14]

Answer:

y- intercept --> Location on graph where input is zero

f(x) < 0         --> Intervals of the domain where the graph is below the x-axis

x- intercept --> Location on graph where output is zero

f(x) > 0         --> Intervals of the domain where the graph is above the x-axis

Step-by-step explanation:

Y-intercept: The y-intercept is equivalent to the point where x= 0. 'x' is the input variable in an equation, therefore the y-intercept is where the input, or x, is equal to 0.

f(x) <0: Notice the 'lesser than' sign. This means that the value of f(x), or 'y', is less than 0. This means that this area consists of intervals of the domain below the x-axis.

X-intercept: The x-intercept is the location of the graph where y= 0, or the output is equal to 0.

f(x) >0: In this, there is a 'greater than' sign. This means that f(x), or 'y', is greater than 0. Therefore, this consists of intervals of the domain above the x-axis.
