In the given figure there are 3 graphs
The line represents a linear function
The parabola represents a quadratic function
The third graph which approaches to the negative part o the x-xis is the exponential function
The x-intercept of the line is (-2, 0)
x-intercept means intersect the x-axis at point (-2, 0)
There is only one graph that intersects the x-axis at (-2, 0)
It is the line, the linear function h(x)
The range is between 0 to infinity (0, ∞)
The range is the values of y
There is only one graph that has all values of y over the x-xis
it is f(x) the exponential function
We can form a system of equations:
x*y=90
and
x=2y+3.
Solving gives dimensions of 15 feet by 6 feet.

First, to make the equation easier to read, you want to add the x’s together. you should then get 2.6x-3.8=-9. then, you want to add the 3.8 to both sides, to make the x stand alone. you should end up with 2.6x=-5.2. to find x, you then want to divide both sides by 2.6. your final answer after dividing should be x=-2
Answer:
0.5
Step-by-step explanation:
Solution:-
- The sample mean before treatment, μ1 = 46
- The sample mean after treatment, μ2 = 48
- The sample standard deviation σ = √16 = 4
- For the independent samples T-test, Cohen's d is determined by calculating the mean difference between your two groups, and then dividing the result by the pooled standard deviation.
Cohen's d = 
- Where, the pooled standard deviation (sd_pooled) is calculated using the formula:
- Assuming that population standard deviation and sample standard deviation are same:
SD_1 = SD_2 = σ = 4
- Then,
- The cohen's d can now be evaliated:
Cohen's d =
