(72*78*85*90*90)/(68*84*91*108) (There's an easier way than multiplying out the giant products 72 78 85 90 98 and 68 84 91 108)H

Sveta_85 [38]

Cancel common factors. For instance,

$\dfrac{72}{68}=\dfrac{2^3\cdot3^2}{2^2\cdot17}=\dfrac{2\cdot3^2}{17}=\dfrac{18}{17}$

For this expression, we have

$\dfrac{72\cdot78\cdot85\cdot90^2}{68\cdot84\cdot91\cdot108}=\dfrac{2^6\cdot3^7\cdot5^3\cdot13\cdot17}{2^6\cdot3^4\cdot7^2\cdot13\cdot17}=\dfrac{3^3\cdot5^3}{7^2}=\dfrac{15^3}{7^2}=\dfrac{3375}{49}$

What is the area of this figure? ___ units^2

enot [183]

Answer:

$42\ units^{2}$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of a rectangle plus the area of two triangles

Find the area of rectangle

Observing the graph

The area of rectangle is equal to

$A=bh=(2+5)(2+2)=28\ units^{2}$

Find the area of the top triangle

$A=\frac{1}{2}bh=\frac{1}{2}(2+5)(4-2)=7\ units^{2}$

Find the area of the bottom triangle

$A=\frac{1}{2}bh=\frac{1}{2}(2+5)(-2+4)=7\ units^{2}$

the area of the figure is equal to

$A=28\ units^{2}+7\ units^{2}+7\ units^{2}=42\ units^{2}$

As part of a study of the association between smoking and risk of squamous cell carcinoma, a logistic regression model was estim

AlekseyPX

Answer:

0.44

Step-by-step explanation:

Given the estimated logistic regression model on risk of having squamous cell carcinoma

-4.84 + 4.6*(SMOKER)

SMOKER = 0 (non-smoker) ; 1 (SMOKER)

What is the predicted probability of a smoker having squamous cell carcinoma?

exp(-4.84 + 4.6*(SMOKER)) / 1 + exp(-4.84 + 4.6*(SMOKER))

SMOKER = 1

exp(-4.84 + 4.6) / 1 + exp(-4.84 + 4.6)

exp^(-0.24) / (1 + exp^(-0.24))

0.7866278 / 1.7866278

= 0.4402863

= 0.44

Find the other endpoint of the line segment with the given endpoint and midpoint. Endpoint: (9,8) Midpoint (0,9)

shepuryov [24]

Answer:

(-9, 10)

Step-by-step explanation:

The location of the midpoint of a line with endpoint at ( $x_1,y_1$ ) and ( $x_2,y_2$ ) is given as (x, y). The location of x and y are:

$x = \frac{x_1+x_2}{2},y=\frac{y_1+y_2}{2}$

Given the endpoint (9,8) and Midpoint (0,9), the location of the other endpoint can be gotten from:

$0=\frac{9+x_2}{2}\\ \\9+x_2=0\\\\x_2=-9\\\\Also,9=\frac{8+y_2}{2}\\ \\8+y_2=18\\\\y_2=18-8\\\\y_2=10$

Hence the endpoint is at (x2, y2) which is at (-9, 10)
