Answer:
(a) the time for the event of the highest 5% is 15.29 minutes.
(b) the time for the event of the lowest 50% is 12 minutes.
(c) the time for the event of the middle 95% is 8.08 minutes and 15.92 minutes.
(d) the time for the event of the lowest 80% is 13.68 minutes.
Step-by-step explanation:
We are given that the time required to cook a pizza at a neighborhood pizza joint is normally distributed with a mean of 12 minutes and a standard deviation of 2 minutes.
Let X = the time required to cook a pizza at a neighborhood pizza joint.
The z-score probability distribution for the normal distribution is given by;
Z = [tex]\frac{X-\mu}{\sigma}[/tex] ~ N(0,1)
where, [tex]\mu[/tex] = mean time = 12 minutes
[tex]\sigma[/tex] = standard deviation = 2 minutes
(a) We have to find the time for the event of the highest 5%, that means;
P(X > x) = 0.05 {where x is the required time}
P( [tex]\frac{X-\mu}{\sigma}[/tex] > [tex]\frac{x-12}{2}[/tex] ) = 0.05
P(Z > [tex]\frac{x-12}{2}[/tex] ) = 0.05
Now, in the z table, the critical value of x that represents the top 5% of the area is given as 1.645, i.e;
[tex]\frac{x-12}{2}=1.645[/tex]
[tex]{x-12}=1.645\times 2[/tex]
x = 12 + 3.29 = 15.29 minutes.
Hence, the time for the event of the highest 5% is 15.29 minutes.
(b) We have to find the time for the event of the lowest 50%, that means;
P(X < x) = 0.50 {where x is the required time}
P( [tex]\frac{X-\mu}{\sigma}[/tex] < [tex]\frac{x-12}{2}[/tex] ) = 0.50
P(Z < [tex]\frac{x-12}{2}[/tex] ) = 0.50
Now, in the z table, the critical value of x that represents the lowest 50% of the area is given as 0, i.e;
[tex]\frac{x-12}{2}=0[/tex]
[tex]{x-12}=0[/tex]
x = 12 + 0 = 12 minutes.
Hence, the time for the event of the lowest 50% is 12 minutes.
(c) We have to find the time for the event of the middle 95%, that means we have to find the time for the event of 2.5% and above 97.5%;
Firstly, the time for the event of the lowest 2.5%, i.e;
P(X < x) = 0.025 {where x is the required time}
P( [tex]\frac{X-\mu}{\sigma}[/tex] < [tex]\frac{x-12}{2}[/tex] ) = 0.025
P(Z < [tex]\frac{x-12}{2}[/tex] ) = 0.025
Now, in the z table, the critical value of x that represents the lowest 2.5% of the area is given as -1.96, i.e;
[tex]\frac{x-12}{2}=-1.96[/tex]
[tex]{x-12}=-1.96 \times 2[/tex]
x = 12 - 3.92 = 8.08 minutes.
Firstly, the time for the event of the below 97.5%, i.e;
P(X < x) = 0.975 {where x is the required time}
P( [tex]\frac{X-\mu}{\sigma}[/tex] < [tex]\frac{x-12}{2}[/tex] ) = 0.975
P(Z < [tex]\frac{x-12}{2}[/tex] ) = 0.975
Now, in the z table, the critical value of x that represents the top 2.5% of the area is given as 1.96, i.e;
[tex]\frac{x-12}{2}=1.96[/tex]
[tex]{x-12}=1.96 \times 2[/tex]
x = 12 + 3.92 = 15.92 minutes.
Hence, the time for the event of the middle 95% is 8.08 minutes and 15.92 minutes.
(d) We have to find the time for the event of the lowest 80%, that means;
P(X < x) = 0.80 {where x is the required time}
P( [tex]\frac{X-\mu}{\sigma}[/tex] < [tex]\frac{x-12}{2}[/tex] ) = 0.80
P(Z < [tex]\frac{x-12}{2}[/tex] ) = 0.80
Now, in the z table, the critical value of x that represents the lowest 80% of the area is given as 0.8416, i.e;
[tex]\frac{x-12}{2}=0.8416[/tex]
[tex]{x-12}=0.8416 \times 2[/tex]
x = 12 + 1.68 = 13.68 minutes.
Hence, the time for the event of the lowest 80% is 13.68 minutes.

The arithmetic progressions [tex]\{2, 5, 8, 11, \ldots\}[/tex] and[tex]3, 10, 17, 24, \ldots \}[/tex] have some common values. What is the largest value less than 500 that they have in common?
=================================================
Work Shown:
We have two sequences, which we'll call A and B
A = {2,5,8,11,14, 17 ,20,23,26,29,32,35, 38, 41,44,47,50,53,56, 59 ,62...}B = {3,10, 17 ,24,31, 38 ,45,52, 59 , 66...}Both sequences are arithmetic. The first sequence starts at 2, and increases by 3 each time. Sequence B starts at 3 and increases by 7 each time.
The terms in bold are what the two sequences have in common.
-----------
It turns out that the bold terms follow an arithmetic sequence of their own.
The sequence {17, 38, 59, ...} is arithmetic.
Call this sequence C. This sequence starts at 17 and increases by 21 each time. The nth term for sequence C is
C(n) = a+d(n-1)
C(n) = 17+21(n-1)
C(n) = 17+21n-21
C(n) = 21n-4
Plugging in n = 1 leads to C(n) = 17. Also, plug in n = 2 and you should get C(n) = 38. Plugging in n = 3 leads to C(n) = 59. And so on.
-----------
The question is now "what is the largest term in sequence C such that it is less than 500?".
In other words, we want to find the term C(n) where C(n) < 500 and C(n) is as large as possible.
Use a bit of algebra to get
C(n) < 500
21n - 4 < 500
21n < 500+4
21n < 504
n < 504/21
n < 24
So n must be smaller than 24 to get what we want.
Because n is a natural number (positive whole number), we drop to n = 23 to find that
C(n) = 21n-4
C(23) = 21(23)-4
C(23) = 479
The largest value, less than 500, the two original sequences have in common is 479.
If we didn't have the restriction "less than 500", then there would be no largest value as sequence C goes on forever.

On the return journey, her average speed was 10km/hr faster and therefore she completed the return journey 37.5minutes earlier. Find A. The value of y B. Get average speed on the return journey in km/hr C. The total time taken for the whole journey in hrs. Good luck
Answer:
70 km/h
9 hr 22.5 min
Step-by-step explanation:
Given
Distance = 350 kmSpeed = yReturn speed = y + 10Time difference on return = 37.5 min = 37.5/60 hr = 5/8 hrDifference in time as equation:
350/y - 5/8 = 350/(y+10)(8*350 -5y)/8y = 350/(y+10)(y+10)(560 - y)= 8y*70560y - y² +5600 - 10y = 560yy² + 10y - 5600=0y = (-10 ± √(100 +4*5600))/2y = (-10 ±150)/2y= 70 y = -80 not considered as negative valueAverage speed was 70 km/h
Total time = 350/70 + 350/(70+10) = 5 + 4.375 = 9.375 hr = 9 hr 22.5 min

A line segment has a length of approximately 10cm. If a compass is set to a width of 9cm, will it still be possibly to bisect the line segment?
Answer: Yes it is possible to bisect the given segment
The compass width (9) is over half of the segment length (10), so we can form the arcs needed to get the perpendicular bisector.
Rationalise the denominator and find a, b
Answer:
a = 49
b = - 20√2
Step-by-step explanation:
5 - 2√6 / 5 + 2√6
We can rationalise the denominator as follow:
5 - 2√6 / 5 + 2√6
Multiply the numerator and the denominator by the conjugate of
5 + 2√6. The conjugate of 5 + 2√6 is
5 - 2√6
(5 - 2√6 / 5 + 2√6) x (5 - 2√6 / 5 - 2√6)
(5 - 2√6) (5 - 2√6) /(5 + 2√6) (5 - 2√6)
Expand
(25 - 10√6 - 10√6 + 4×6) / (25 - 10√6 + 10√6 + 4×6)
25 - 20√6 + 24 / 25 - 24
25 + 24 - 20√6 / 1
49 - 20√6
Equating 49 - 20√6 with a + b√3, we can obtain the value of a and b as follow:
49 - 20√6 = a + b√3
From the above
a = 49
b√3 = - 20√6
Divide both side by √3
b = - 20√6/√3
Rationalise
b = - 20√6/√3 x √3/√3
b = - 20√(6×3)/ √3×√3
b = - 20√18 / 3
b = - 20√(9×2) / 3
b = - 20 × 3√2 / 3
b = - 20√2
Given info:- Rationalise the denominator and find out the value of "a" and "b"
Given expression: {(5-2√6)/(5+2√6)} = a+b√3
Explanation:-
{(5-2√6)/(5+2√6)} = a+b√3
We know that Rationalising factor of a+b√c is a-b√c.
Therefore, the rationalising factor of 5+2√6 is 5-2√6.
⇛{(5-2√6)/(5+2√6)} × {(5-2√6)/(5-2√6)} = a+b√3
⇛{(5-2√6)(5-2√6)}/{(5+2√6)/(5-2√6)} = a+b√3
⇛{(5-2√6)²}/{5+2√6)(5-2√6)} = a+b√3 [∵(a-b)(a-b)=(a-b)²]
⇛{(5-2√6)²}/{(5)²-(2√6)²} = a+b√3 [∵(a+b)(a-b)=a²-b²]
⇛{(5-2√6)²}/({5*5)-(2*2√6*6)} = a+b√3
⇛{(5-2√6)²}/(25 - 4√6) = a+b√3
⇛{(5-2√6)²}/(25-24) = a+b√3
⇛{(5-2√6)²}/1 = a+b√3
⇛(5-2√6)² = a+b√3
⇛(5)²-(2√6)²+2(5)(2√6) = a+b√3
⇛(5*5) - (2*2√6*6) - 10 - 2√6 = a+b√3
⇛25 - 10 - 4√6 - 2√6 = a+b√3
⇛15 - 4√6 - 2√6 = a+b√3
⇛15 + 6√6 = a+b√3
∴ 15 + 6√6 = a+b√3
On, comparing with both RHS we notice that:
The value of a = 15 and b = 6.

Jim takes great pride in decorating his float for the homecoming parade for his high school. With the $5000 he has to spend, Jim buys 5,000 carnations at $0.30 each, 4,000 tulips at $0.60 each, and 300 irises at $0.25 each. Write an inequality which describes how many roses, r, Jim can buy if roses cost $0.80 each.
Answer:
r = (5000 - [(5000 x 0.3) + (4000 x 0.6) + (300 x 0.25)])0.8
Simplified - r = 820
Step-by-step explanation:
I don't know how to explain it exactly, but I know you have to find out how much the carnations, tulips, and irises all cost,subtract that from how much money he has, and divide what left by the cost of the roses (by multiplying the 0.8 cents, because it's a decimal).
r = (5000 - [(5000 x 0.3) + (4000 x 0.6) + (300 x 0.25)])0.8
r = (5000 - [1500 + 2400 + 75])0.8
r = (5000 - 3975)0.8

Kim can mow the greens at the golf course twice as fast as I can. Working together, we can mow them in 4 hours. How long will it take me to mow the greens alone?
Answer:
12 hours
Step-by-step explanation:
Let x hours be the time it will take you to mow the greens at the golf course.
Since Kim can mow twice as fast, it will take Kim x / 2 hours to mow the greens.
In 1 hour, you will mow 1 / x of the greens
in 1 hour, Kim will mow 1 / (x / 2) of the greens= 2 / x of the greens
In 4 hours, you will mow 4 * 1 / x of the course = 4 / x of the greens
In 4 hours, Kim will mow 4 * 1 / (x / 2) of the course = 4 / (x / 2) = 8 / x of the greens.
Since we are dealing in fraction, the sum of the amount of greens that they would individually mow in 4 hours should be 1. i.e
(4 / x) + (8 / x) = 1
12 / x = 1
Solve for x;
x = 12
Therefore, it will take you 12 hours to mow the greens alone.
Solve for y.
2y^2 - 10y+44 =(y-7)^2
If there is more than one solution, separate them with commas.
Answer:
y = -5, 1
Step-by-step explanation:
2y² - 10y + 44 = (y - 7)²
expand (y - 7)²
(y - 7)² = y² - 14y + 49
move it to the left
(2y² - 10y + 44) - (y² - 14y + 49) = 0
distribute the (-)
2y² - 10 y + 44 - y² + 14y - 49 = 0
combine like terms
y² - 4y -5
factor with factoring X
y² + 5y - y - 5 = 0
factor by grouping ↓
factor out a y from first half of equation
y(y + 5) - y - 5 = 0
factor out a (-) from second half of equation
y(y +5) - (y + 5) = 0
(y +5)(y - 1) = 0
y = -5, 1
Jake's water bill is $24.60 per month plus $2.00 per ccf (hundred cubic feet) of water. What is the maximum number of ccf Jake can use if he wants his bill to be no more than $64.00?
Answer:
Jake can use 19.70 ccf to not exceed $ 64.00 in water bill.
Step-by-step explanation:
The cost function of water bill is:
[tex]C = C_{f}+C_{v}[/tex]
Where:
[tex]C_{f}[/tex] - Fix costs, measured in USD.
[tex]C_{v}[/tex] - Variable costs, measured in USD.
The fix and variable costs are, respectively:
[tex]C_{f} = 24.60[/tex]
[tex]C_{v} =2\cdot \left(\frac{Q}{100} \right)[/tex]
Where [tex]Q[/tex] is the water capacity consumed within a month, measured in cubic feet. Therefore, first formula is expanded:
[tex]C = 24.60+2\cdot \left(\frac{Q}{100} \right)[/tex]
If [tex]C = 64\,USD[/tex], the maximum water capacity is:
[tex]64 = 24.60+2\cdot \left(\frac{Q}{100} \right)[/tex]
[tex]39.40 = 2\cdot \left(\frac{Q}{100} \right)[/tex]
[tex]Q = 1970\,ft^{3}[/tex]
Which is equivalent to 19.70 ccf.
a pitcher can hold 8 times as much as a glass. the pitcher holds 64 ounces which model shows this comparison.
Answer:
A model that shows a pitcher holding 8 times the amount of a glass
Step-by-step explanation:
I would need a picture of the models, but I think I can still help.
Any model that shows a pitcher holding 8 times as much as a glass is the correct model. Be sure to read carefully so you pick the right model.
The equation y = 8x shows the relationship between the holding capacity of the pitcher and glass, and x = 64/8 shows the total amount held by the glass.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the pitcher can hold x ounces
And the glass can hold y ounces
From the given problem:
y = 8x
The above equation modeled the relationship between the holding capacity of the pitcher and glass.
If y = 64
Then x = 64/8 = 8 ounces
Thus, the equation y = 8x shows the relationship between the holding capacity of the pitcher and glass, and x = 64/8 shows the total amount held by the glass.

Hey there! I'm happy to help!
Squaring a number is when you multiply it by itself. You represent this with an exponent, which is a little number above the number that you multiply by itself. When you square a number, this exponent is two.
1²=1
2²=4
3²=9
4²=16
5²=25
6²=36
7²=49
8²=64
9²=81
10²=100
The square root is basically just doing this backwards. It is finding the number that can be multiplied by itself to equal that number. You represent this with the √ symbol.
√1=1
√4=2
√9=3
√16=4
√25=5
√36=6
√49=7
√64=8
√81=9
√100=10
We know that 8 multiplied by itself is equal to 64. This means that the square root of 64 is 8.
I hope that this helps you out! Have a wonderful day! :D

Answer:
1.54 and 1.7 I believe
Step-by-step explanation:
Answer:
The full steel tire is 1.76 pounds and the lighter wheel is 1.54 pounds
Step-by-step explanation:
To find how many pounds each tire is, divide the weight in grams by 453.592
Full steel tire:
800/453.592 = 1.76 pounds
Lighter wheel:
700/453.592 = 1.54 pounds
So, the full steel tire is 1.76 pounds and the lighter wheel is 1.54 pounds
