Step-by-step explanation:
1) -30 meters because descend means decrease
2) 20 meters because above means positive
3) 0 because it does not change

Answer:<u>
158.7 is the answer</u></h2><h2><u>or it can be</u>
<u>89.7</u></h2>
Step-by-step explanation:
<h2>
<u>69 + Percentage increase =
</u></h2><h2>
<u>69 + (130% × 69) =
</u></h2><h2>
<u>69 + 130% × 69 =
</u></h2><h2>
<u>(1 + 130%) × 69 =
</u></h2><h2>
<u>(100% + 130%) × 69 =
</u></h2><h2>
<u>230% × 69 =
</u></h2><h2>
<u>230 ÷ 100 × 69 =
</u></h2><h2>
<u>230 × 69 ÷ 100 =

Answer:
The probability is 0.080757
Step-by-step explanation:
We start by calculating the z-score
z-score = (x-mean)/SD/ √n
In this case;
x = 247 , mean = 240, SD = 50 and n = 100
z-score = (247-240)/50/√100
z-score = 7/50/10
= 7/5 = 1.4
So the probability we want to calculate is;
P( x > 1.4)
we can use the standard normal distribution table for this
P(x > 1.4) = 0.080757
