Answer:
4.95 x 10^-1
Step-by-step explanation:
4.95 x 10^-1
P(<em>Z</em> ≥ <em>z</em>) = 1 - P(<em>Z</em> ≤ <em>z</em>) = 0.06
==> P(<em>Z</em> ≤ <em>z</em>) = 0.94
==> <em>z</em> ≈ 1.7507
Answer:
The actual length of the helicopter is <u>23 feet</u>.
Step-by-step explanation:
Given:
On a scale drawing, a helicopter is 2.3 feet long.
The scale on the drawing shows a ratio of 1 foot to 10 feet.
Now, to find the actual length of the helicopter.
Let the actual length of helicopter be
.
On scale drawing length of helicopter = 2.3 feet.
The scale on the drawing shows a ratio = 1:10.
Now, as ratios are given so by setting proportion we solve it:

<em>By cross multiplying we get:</em>
⇒ 
⇒ 
⇒ 
Therefore, the actual length of the helicopter is 23 feet.
Sorry If I got it incorrect
x > 3
Subtract 3 from both sides
-4x + 3 - 3 < -9 -3
Simplify
-4x < -12
Multiply both sides by -1 (reverse the inequality)
(-4x) (-1) > (-12) (-1)
Simplify
4x > 12
Divide both sides by 4
4x/4 > 12/4
Simplify
x > 3
