Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean $440 and standard deviation $10.
This means that [tex]\mu = 440, \sigma = 10[/tex]
How much should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05?
This is x for which
P(X > x) = 0.05
So this is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95, so X when Z = 1.645.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.645 = \frac{X - 440}{10}[/tex]
[tex]X - 440 = 10*1.645[/tex]
[tex]X = 456.45[/tex]
$456.45 should be budgeted.

A rectangular prism has a length of 3ft, a height of 6ft, and a width of 20ft. What is its
volume, in cubic ft?
Answer:
360
Step-by-step explanation:
To solve to volume you need to times the width, length, height. so 3 times 6 is 18 and 18 times 20 is 360.

Enter the number that belongs in the green box,
[?]
please help this is urgent
Answer:
missing angle = 30 degrees
Step-by-step explanation:
all triangles have an interior angle or 180 degrees.
to find the missing angle, just take the know angles and add them together:
120 + 30 = 150
then take the sum and subtract it from 180:
180 - 150 = 30
Answer:
120° +30° +z=180°150° +z =180°z= 180°-150°z=30°Mean of eight observations is 25. If one observation 11 is excluded , find the mean of the remaining.
Answer:
Mean = 27
Step-by-step explanation:
Given mean = 25
No of observations (N) = 8
We know,
Mean = Sum / N
25 = Sum / 8
Sum = 25 x 8
Sum = 200
Since an observation 11 is removed,
New sum = 200 - 11 = 189
New no. of observation (N) = 8 - 1 = 7
Now,
Mean of remaining observations = New Sum / New N
= 189/7
= 27
Answer:
mean=25
n=8
sum of observation=?
we have
mean=sum/n
sum=25×8=200
if one observation is excluded
sum will be =200-11=189
[n]no of observation = 8-1=7
new mean =new sum/new n=189/7=27
the mean of the remaining is 27

what is x
I'm confused
Answer:
x = 3
Step-by-step explanation:
the diagonals bisect each other so:
6x + 2 = 20
subtract 2 from both sides of the equation:
6x = 18
x = 18/6
x = 3

The Cobb-Douglas production model is a function that relates production outputs with a combination of different inputs. Agricultural data from 44 countries around the world, concerning agricultural production Q, labor L, capital K, fertilizer F, and hectares of arable land H, can be used to create an agricultural production model for countries using a Cobb-Douglas function given by
Q= 3.41 L^0.266 .K^2.06 F^0.299.H^1.41
The exponents in the Cobb-Douglas model are called elasticities. Find the percentage increment in production if a country has a 1% increase in Labor.
Answer:
0.266 percent
Step-by-step explanation:
With labor increasing by 1 percent, we are to find how much level of production would also increase given the coubglas function in the question.
Level of production = ∆Q/Q
We differentiate the function Q with respect to Labour, L.
∆Q/∆L = 0.266Q/L
∆Q/Q = 0.266∆L/L
∆L/L = 1
∆Q/Q x 100 = 1 *0.266
= 0.266%

400 people were surveyed
about their eye color. 8% of
the people surveyed have
green eyes. How many
people had green eyes?
Answer:
32 people
Step-by-step explanation: If there are 400 people and there is 8% of that, then first convert 8% to a decimal so its easier to work with. The multiply with 400:
0.08 * 400 = 32
Answer: 32 people have green eyes

the measures of the angles of a triangle are shown in the figure below. solve for x
Answer:
the the figure shown x=7
Answer:
7°
Step-by-step explanation:
7x + 5 °+ 36° + 90 °= 180° ( being sum of angles of triangle )
7x + 131° = 180°
7x = 180 °- 131 °
7x = 49°
x = 49° / 7
x = 7°

Kite x=1, y=7
Step-by-step explanation:
It is a kite.
The two lines on the bottom corners of the kite mean they have the same value.
X=1 so 3x+4
3 *1 +4=7
And: x+6
1+6=7.
X+4=1+4=5.
Y=7 so y-2
7-2=5.

Answer:
m<1 = 97°
Step-by-step explanation:
<1 and 83° are same-side interior angles. Same-side interior angles are supplementary. This implies that:
m<1 + 83° = 180°
Therefore:
m<1 + 83° - 83° = 180° - 83° (subtraction property of equality)
m<1 = 97°
Answer:
<1=97°
steps:
<1+83=180 co interior angle
<1=180-83=97°
