Determine the area under the standard normal curve that lies to the right of the z-score 0.48 and to the left of the z-score 0.7

pychu [463]

Answer:

The area lies to the right of the z-score 0.48 means all the values greater than it. This can be calculated on a graphing calculator using the function normCdf, where

Lower bound = 0.48
Upper bound = 9999
Mean = 0
Standard deviation = 1

<u>The result would be normCdf(0.48,9999,0,1) ≈ </u><u>0.315614</u>

<u />

The area lies to the left of the z-score 0.79 means all the values less than it. This can be calculated on a graphing calculator using the function normCdf, where

Lower bound = -9999
Upper bound = 0.79
Mean = 0
Standard deviation = 1

<u>The result would be normCdf(-9999,0.79,0,1) ≈</u><u> 0.785236</u>

If given f(x) = –4x – 2 and g(x) = 2x, what is (f · g)(x)?

Rashid [163]

Answer:

-8x^2 -4x

Step-by-step explanation:

f(x) = –4x – 2

g(x) = 2x

(f · g)(x) = (-4x-2) * (2x)

distribute

= -2x*4x -2x*2

= -8x^2 -4x

If f(x) = 3 – 2x and g (x) = StartFraction 1 Over x + 5 EndFraction, what is the value of (StartFraction f Over g EndFraction) (

vredina [299]

For this case we have the following functions:

$f (x) = 3-2x\\g (x) = \frac {1} {x + 5}$

We must find: $\frac {f} {g} (8)$

By definition we have to:

$\frac {f} {g} (x) = \frac {f (x)} {g (x)}$

So:

$\frac {f (x)} {g (x)} = \frac {3-2x} {\frac {1} {x + 5}} = (3-2x) (x + 5)$

Thus, we have to:

$\frac {f} {g} (8) = (3-2 (8)) (8 + 5) = (3-16) (13) = - 13 * 13 = -169$

So, the value is -169

1) The perimeter of a rectangular classroom floor is 90 feet. The length of the floor is twice the

lana [24]

Answer: The equation would NOT help us solve for the length and width of the classroom is " $x + 2y = 90$ ".

Step-by-step explanation:

Let y be the width of the rectangular classroom floor and x be the length of the rectangular classroom floor .

Given ,

The perimeter of a rectangular classroom floor is 90 feet.

The length of the floor is twice the width.

i.e. Length =2 (width)

i.e. x= 2y ..(i)

Also, perimeter = 2(length+width)

$i.e. 2(x+y)=90\\\\\Rightarrow\ 2x+2y=90$

When we put value of x from (i), we get

$2(2y) + 2y = 90$

Hence, the equation would NOT help us solve for the length and width of the classroom is " $x + 2y = 90$ ".
