Answer:
The psychologist finds that the estimated Cohen's d is 0.583.
Step-by-step explanation:
The Cohen's d is used to calculate the effect size, appied when a null hypothesis is rejected.
It can be calculated for this case of population mean as:
![d=\dfrac{M-\mu}{\sigma}=\dfrac{6.5-5.8}{1.2}=\dfrac{0.7}{1.2}=0.583](https://tex.z-dn.net/?f=d%3D%5Cdfrac%7BM-%5Cmu%7D%7B%5Csigma%7D%3D%5Cdfrac%7B6.5-5.8%7D%7B1.2%7D%3D%5Cdfrac%7B0.7%7D%7B1.2%7D%3D0.583)
The psychologist finds that the estimated Cohen's d is 0.583.
Answer:
The slope is
.
Step-by-step explanation:
The equation is conveniently in slope-intercept form.
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
m - slope
b - y-intercept
-2/3 is in m's spot, so it is the slope of the equation.
![y=\boxed{m}x+b\\\\y=\boxed{-\frac{2}{3}}x+5](https://tex.z-dn.net/?f=y%3D%5Cboxed%7Bm%7Dx%2Bb%5C%5C%5C%5Cy%3D%5Cboxed%7B-%5Cfrac%7B2%7D%7B3%7D%7Dx%2B5)
Hope this helps.
Just multiply the bases and add up the exponents.

Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
y = 2x² + 12x + 1
To express in vertex form use the method of completing the square.
The coefficient of the x² term must be 1 , thus factor out 2 from 2x² + 12x
y = 2(x² + 6x) + 1
add/ subtract ( half the coefficient of the x- term)² to x² + 6x
y = 2(x² + 2(3)x + 9 - 9) + 1
= 2(x + 3)² - 18 + 1
= 2(x + 3)² - 17 → C
