A set of data is normally distributed with a mean of 455 and a standard deviation of 25. What percent of the data is in the interval 405–455?
a.
47.5%
c.
68.3%
b.
49.85%
d.
34.15%
Answer:
a. 47.5%
Step-by-step explanation:
1. Find the z-score for 405: 405-455/25 = -2
2. Find the z-score for 455: 455-455/25 = 0
3. Using technology or a chart, find the percentage that corresponds with the z-scores: -2 = 0.0228 or 2.28%, AND 0 = 0.5000 or 50%
4. Find the difference between the percentages by subtracting them: 50% - 2.28% = 47.72%
5. Most of the time, the answers aren't exact, so since 47.72% is closest to 47.5%, I would say that's the answer.
To the nearest tenth of a centimeter, how tall is a cylinder with a radius of 8.4 cm and volume of 3119.5 cm3. Give the approximate answer rounded to 2 decimal places.
Thank you!
Answer:
r=8.4cm
v=3119.5cmcube
volume of a cylinder
=pie r square height
pie=22/7
22/7×8.4×8.4×h=3119.5cm cube
221.76cmsquareh=3119.5cm cube
___________________________
221.76cm square(both sides)
h=14.07cm
The height of the cylinder is h = 14.09 cm
Given data:
To find the height of the cylinder, the formula for the volume of a cylinder: V = πr²h, where V is the volume, r is the radius, and h is the height.
Given that the radius is 8.4 cm and the volume is 3119.5 cm³, substitute these values into the formula and solve for h.
3119.5 cm³ = π(8.4 cm)²h
To isolate h, divide both sides of the equation by π(8.4 cm)²:
h = 3119.5 cm³ / (π(8.4 cm)²)
Now, calculate the approximate value of h as:
h ≈ 3119.5 / (π * 8.4²)
≈ 3119.5 / (3.14 * 70.56)
≈ 3119.5 / 221.1264
≈ 14.0989 cm
Hence , the height is 14.09 cm

The diagram below shows Cameron's budgeted expenses for a trip he is planning. O $46.08 O 580 O $1,200 O $4,608 CLEAR ALL Cameron has budgeted $240 for meals during his full trip. What is the total budget for the trip?
A $46.08
B $80
C $1,200
D $4,608
Answer:
C $1,200
Step-by-step explanation:
The computation of the total budget fro the trip is as follows:
Since it is given that the budgeted amount for meals is $240 i.e. equivalent to 20%
By this information we can easily compute other budgeted expenses
For Lodging
= $240 × 0.32 ÷ 0.20
= $384
For transportation
= $240 × 0.36 ÷ 0.20
= $432
For Gifts
= $240 × 0.12 ÷ 0.20
= $144
Now the total budget for the trip is
= $384 + $240 + $432 + $144
= $1,200

Are 5x + 9 - 2x = 12 and 3x = 3 equivalent equations
Answer:
Yes
Step-by-step explanation:
If you simplify the 1st equation,
5x + 9 - 2x = 12
Add like terms
3x + 9 = 12
Subtract the 9 from both sides
3x = 3
It gives you the same equation as the other one
Answer:
yes they both equal 1

It is said that if you are with someone else, you do not have to outrun the wolf, you just
have to outrun the other person.
Suppose that a wolf can run 15 m/s, you can run 10 m/s and your friend can run 5 m/s.
You start 15 meters away from the wolf and your friend starts 20 meters, away from the
wolf.
Set up three equations and then answer using your perfered method
(table/graphing/theory): Who gets caught first and when (in seconds)?
Answer:
The three equations:
y = 15x, wolfy = 10x + 15, youy = 5x + 20, friendCompare the equations with wolf and you and with wolf and your friend:
15x = 10x + 155x = 15x = 3 secondsIt will take 3 seconds before you are caught by the wolf
15x = 5x + 2010x = 20x = 2 secondsIt will take 2 seconds before your friend is caught by the wolf, he will be caught a second before you.

Estimate the perimeter and the area of the shaded figure
Show how you got your answer
Answer:
Perimeter = 16 feet
Total Surface Area = 24 sq ft.
Step-by-step explanation:
Let's assume that each square is equal to 1 foot. Using this we can estimate the perimeter and area as the following. For perimeter, we simply add all the squares distances surrounding the shaded object.
Perimeter = 16 feet (4 feet for the top and bottom and 2 feet every diagonal)
For the area, we need to calculate the area of the square in the middle and then the area of the two triangles.
Square = L * W
Square = 4 * 4
Square = 16 sq ft
Triangle = 0.5 * Base * Height
Triangle = 0.5 * 4 * 2
Triangle = 4 sq ft
Both triangles = 4 sq ft * 2 = 8 sq ft.
Now we add both area totals:
Total Surface Area = 16 + 8
Total Surface Area = 24 sq ft.

50 POINTS Vanessa has 6 dimes and 2 pennies. Joachim has 1 dollar, 3 dimes, and 5 pennies. Jimmy has 5 dollars and 7 pennies. They want to put their money together to buy a game that costs $8.00. Do they have enough money to buy the game? If not, how much more money do they need? SHOW WORK
Vanessa: a dime = 10 cents = 0.10
A penny = 1 cent = 0.01
6 x 0.10 = 0.60
2 x 0.01 = 0.02
Total = 0.60 + 0.02 = 0.62
Joachim : a dollar = 1.00
3 x 0.10 = 0.30
5 x 0.01 = 0.05
Total = 1.00 + 0.30 + 0.05 = 1.35
Jimmy: total = 5.00 + 0.07 = 5.07
Total of all 3: 0.62 + 1.35 + 5.07 = $7.04
This is less than $8 so they don’t have enough.
They need: 8.00 - 7.04 = $0.96 more
Answer:they need more money
Step-by-step explanation: they need 96 more cents

I know it’s supplementary but I can’t find the value of X
Answer:
x = 18
Step-by-step explanation:
Answer:
x = 18
Step-by-step explanation:
Supplementary angles = 180°
110° + ( 3x + 16° ) = 180
110° + 3x + 16 ° = 180
126° + 3x = 180
3x = 180 - 126
3x = 54°
x = 54/3
x = 18
Find the lateral area of the cylinder to the nearest tenth.
Answer:
Lateral area of the cylinder = 62.85 cm²
Step-by-step explanation:
Given:
Diameter of cylinder = 10 cm
Radius of cylinder = 10 / 2 = 5 cm
Height of cylinder = 2 cm
Find:
Lateral area of the cylinder
Computation:
Lateral area of the cylinder = 2πrh
Lateral area of the cylinder = 2(22/7)(5)(2)
Lateral area of the cylinder = 2(22/7)(10)
Lateral area of the cylinder = (440/7)
Lateral area of the cylinder = 62.85 cm²

After a while, Jada picks up a coin that seems different than the others. She notices that the next day, only half of the coin is left!
On the second day, only 1/4 of the coin is left.
On the third day, 1/8 of the coin remains.
What fraction of the coin remains after 6 days?
What fraction of the coin remains after 28 days? Write an expression to describe this without computing its value.
Does the coin disappear completely? If so, after how many days?
Answer:
After 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.
Step-by-step explanation:
Since after a while, Jada picks up a coin that seems different than the others, and she notices that the next day, only half of the coin is left, while on the second day, only 1/4 of the coin is left and, on the third day, 1/8 of the coin remains, to determine what fraction of the coin remains after 6 days, what fraction of the coin remains after 28 days and determine if the coin will disappear completely, the following calculation must be performed:
1/2 ^ 6 = X
0.015625 = X
1/64 = X
1/2 ^ 28 = X
0.0000000037252902984619140625 = X
1/268435456 = X
Thus, after 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.
X is proportional to ✓y where y>0 .
y is increased by 44%
work out the percentage increase in x
Answer:
20%
Step-by-step explanation:
x = k√y
Increase y by 44%. y becomes 1.44y.
x = k√(1.44y)
x = 1.2k√y
x went from k√y to 1.2k√y.
(1.2k√y)/(k√y) = 1.2
x is now 1.2 times greater than it was, so the increase in x is 20%.
Answer: 20%
