P(> or =70) =0.65
P(Collins inside) =0.80
P(not 70) = 1-P(70) =>0.35
P(Collins inside) = 0.1
Then P(70 AND Collin inside) .65 x .8 =0.52
P( not 70 AND Collin Outside = 0.35 x 0.1=0.035
TOTAL Possibility [(70 AND Inside) OR (not 70 AND Outside):
=0.52 + 0.034 =0.555

the area of a rectangular photograph is 35 square inches. If the width of the photo is 5 inches how tall is the photo
Vika [28.1K]
We know that:

Area= length*width

Plug in the stuff you know.

35= length(tall)*5

Divide both sides by 5.

7= length

The photo is 7 inches tall.

I hope this helps!

I WILL GIVE BRIANLIEST WHOEVER ANSWER!!<br> 17. Find (f/g)(X) for the following functions.
Genrish500 [490]

Answer:

Option 3

Step-by-step explanation:

(f/g)(x) = f(x)/g(x)

Since g(x) is in the denominator, it can't be 0.

(Functions is undefined when the denominator = 0)

This fraction becomes undefined when:

-14x² - 1 = 0

14x² = -1

x² = -1/14

So x² should not be -1/14

Find the distance between the two points rounding to the nearest tenth (if needed)
Ede4ka [16]

Answer:

6.3 units (nearest tenth)

Step-by-step explanation:

\boxed{Distance \: between \: 2 \: points =  \sqrt{ {(x1 - x2)}^{2} +  {(y1 - y2)}^{2}  } }

Using the formula above,

distance between (-8, 6) and (-6, 0)

=  \sqrt{ {[ - 8 - ( - 6)]}^{2}  +  {(6 - 0)}^{2} }

=  \sqrt{ {( - 8 + 6)}^{2}  +  {(6 - 0)}^{2} }

=  \sqrt{ {( - 2)}^{2} + 6^{2}  }

=  \sqrt{4 + 36}

=  \sqrt{40}

= 6.3 units (nearest tenth)
