Just use your right angled triangle formula.

A= $\frac{ab}{2}$

Plug n chug

A= $\frac{11*13}{2}$
A=71.5 $in^{2}$

There is 5/6 of an apple pie left from dinner. Tomorrow, Victor plans to eat 1/6 of the pie that was left. How much of the whole

Lady_Fox [76]

5/6 = 83%
1/6= 16%

83% of the apple pie was left from dinner.
Victor is gonna eat 16% of the pie tomorrow
You have to subtract 16% from 83%
In other words 5/6-1/6

The denominators are same so you don't have to do anything to them
5/6 - 1/6

5-1=4

4/6 of the pie would be left
In simplest form it would be

4/6 <span> ÷2</span>
=2/3

2/3 is in simplest form

Solve for 3/4u = 12<br> .<br> Simplify your answer as much as possible.

Wittaler [7]

Answer:

u = 16

Step-by-step explanation:

Given

$\frac{3}{4}$ u = 12

Multiply both sides by 4 to eliminate the fraction

3u = 48 ( divide both sides by 3 )

u = 16

Data:

15 16 14 15 19 17

n=6 points

sum is 96

mean is 96/6 = 16

Now we look at the absolute deviations, each of which is the absolute value of a score minus the mean, basically the distance of the score to the mean .

Scores 15 16 14 15 19 17

AbsDev 1 0 2 1 3 1

The sum of the absolute deviations is 8 and there are six of them so the

Mean Absolute Deviation = 8/6 = 4/3

Answer: 2. 8/6

Part of the area under this ramp serves for storage. Items can be stored only in the unshaded part of the ramp

Mekhanik [1.2K]

Answer:

48.1 m³ available, 2.5m³ not available

Step-by-step explanation:

Tan(X) = 4.5/(5.8+1.7)

Tan X = 3/5

Hypotenuse² = 3² + 5² = 34

Sin X = 3/sqrt(34)

X = 30.96

1/sinX = 1.7/SinY

Y = 61.003°

Third angle: 180 - X - Y = 88.037

Volume

= ½ × 1.7 × 1 × sin(88.038) × 3

= .

= 2.548

= 2.5m³

Available for storage:

½×4.5×7.5×3 - 2.548

= 48.077 = 48.1 m³

The length of a phone conversation is normally distributed with a mean of 4 minutes and a standard deviation of 0.6 minutes. Wha

Arlecino [84]

The z-score for 5 minutes is found from:
$z=\frac{X-\mu}{\sigma}
$
$z=\frac{5-4}{0.6}=1.667$
Reference to a normal distribution table shows that the cumulative probability for a z-score of 1.667 is around 0.9522.
Therefore the probability that a conversation lasts for longer than 5 minutes is:
1 - 0.9522 = 0.048 to 3 d.p.
