1) For this situation at Fry's grocery store we need to find out the Probability of those workers who worked less than 32 hours weekly.
2) We need to find out the Z score, using this formula:
\(Z=\frac{x-\mu}{\sigma}\Rightarrow Z=\frac{32-28}{4}=\frac{4}{4}=1\)Notice that the Z score we start with this and then go check at a Z score table.
\(P(Z<1)=0.8413\)3) So we can state that approximately 84.13% of those workers, worked fewer than 32 hours

Rick Rich owns a Mercedes dealership. Mercedes has 5 models, 4 standard options packages, and 5 colors. If Rick wants to immediately be able to deliver any car (model, option package, color), how many cars must Rick have on hand?
Rick would need to have at least 100 cars on hand to immediately be able to deliver any car (model, option package, color).
To immediately deliver any car, Rick Rich's dealership must have all possible combinations of Mercedes models, option packages, and colors in stock.
With five models, four option packages, and five colors, there are 5 x 4 x 5 = 100 possible combinations.
Therefore, Rick would need to have at least 100 cars on hand, each representing a unique combination of model, option package, and color. It's worth noting that having exactly 100 cars on hand would only allow Rick to deliver one of each possible combination, so it may be prudent to have additional inventory on hand to meet demand for more popular combinations.

Solve the following system by graphing
{y=x-4}
{y=-x+6}
1. (1,5)
2.(0,5)
3.(5,0)
4.(5,1)
Answer:
Step-by-step explanation:
When they ask you to solve graphically they want you to construct those functions and note where the two lines intersect as that is the solution to the system of equations. Solving mathematically they will be equal when y=y so we can say
x-4=-x+6 add x to both sides
2x-4=6. add 4 to each side
2x=10. divide each side by 2
x=5, since y=x-4
y=5-4
y=1
So the lines will intersect at the point (5,1)

Given: m∠ELG = 124°
Prove: x = 28
3 lines are shown. A line with points D, L, G intersects a line with points E, L, H at point L. Another line extends from point L to point F between angle E L G. Angle D L E is (2 x) degrees.
Answer:
By using opposite angles of two intersecting straight lines are congruent we proved that x = 28°
Step-by-step explanation:
Opposite angles of two intersecting straight lines are congruent
Therefore ∠DLE = ∠GLH
Here ∠DLE = 2x = ∠GLH
Sum of all angles on a straight line is 180°
Therefore ∠ELG + ∠GLH = 180°
Given that ∠ELG = 124°
124° + ∠GLH = 180°
124° + 2x = 180°
2x = 180° - 124°
2x = 56°
x = 28°

c. (0.70)^4 (0.30).
d. (0.30)^3 (0.70).
e. 0.30.
Answer: (c)
Step-by-step explanation:
Given
A person has a 30% chance of winning a lottery ticket.
Probability of not getting the lottery ticket is 70%
For person to win at fifth ticket, it must fail in first four
So, the probability associated with it is
\(\Rightarrow P=(0.70)\times (0.70)\times (0.70)\times (0.70)\times (0.30)\\\\\Rightarrow P=(0.70)^4\cdot (0.3)\)
Hence, option (c) is correct.

The base of s is an elliptical region with boundary curve 9x^2 + 4y^2 = 36
Cross sections perpendicular to the x axis are isoscelees right triangle with hypotension in the base.
Correct answer is 24 but I don't know how they go that
Answer:
See below for explanation
Step-by-step explanation:
The area of an isosceles triangle is \(A=\frac{1}{2}bh\), so let's write the base as an equation of y:
\(\displaystyle 9x^2+4y^2=36\\\\4y^2=36-9x^2\\\\y^2=9-\frac{9}{4}x^2\\\\y=\pm\sqrt{9-\frac{9}{4}x^2\)
As you can see, our ellipse consists of two parts, so the hypotenuse of each cross-section will be \(\displaystyle 2\sqrt{9-\frac{9}{4}x^2\), and each height will be \(\displaystyle \sqrt{9-\frac{9}{4}x^2}\).
Hence, the area function for our cross-sections are:
\(\displaystyle A(x)=\frac{1}{2}bh=\frac{1}{2}\cdot2\sqrt{9-\frac{9}{4}x^2}\cdot\sqrt{9-\frac{9}{4}x^2}=9-\frac{9}{4}x^2\)
Since we'll be integrating with respect to x because the cross-sections are perpendicular to the x-axis, then our bounds will be from -2 to 2 to find the volume:
\(\displaystyle V=\int^2_{-2}\biggr(9-\frac{9}{4}x^2\biggr)\,dx\\\\V=9x-\frac{3}{4}x^3\biggr|^2_{-2}\\\\V=\biggr(9(2)-\frac{3}{4}(2)^3\biggr)-\biggr(9(-2)-\frac{3}{4}(-2)^3\biggr)\\\\V=\biggr(18-\frac{3}{4}(8)\biggr)-\biggr(-18-\frac{3}{4}(-8)\biggr)\\\\V=(18-6)-(-18+6)\\\\V=12-(-12)\\\\V=12+12\\\\V=24\)
Therefore, this explanation confirms that the correct volume is 24!
Define the formula for a parabola (a quadratic function) that has horizontal intercepts (roots) at x = −7 and x = 5 and passes through the point (0, −2).
The formula of the parabola is y = 2/35(x + 7)(x - 5)
How to determine the formula of the parabola?The parameters in the question are given as
Horizontal intercepts (roots) at x = −7 and x = 5 Passes through the point (0, −2).These parameters can be represented as
x₁ = -7 and x₂ = 5
(x, y) = (0, -2)
The quadratic function can be represented as
y = a(x - x₁)(x - x₂)
Substitute the known values in the above equation So, we have the following equation
y = a(x + 7)(x - 5)
At (x, y) = (0, -2), we have

Problem 37
Kaimi had no money at all when he cashed his paycheck. As he left the bank, he bought a piece of candy for
a nickel from a machine. Later, he realized that the money in his pocket was equal to twice his paycheck.
After a quick calculation, he figured out what happened: the teller accidentally switched the dollars and
cents. How much was Kaimi supposed to be paid, and what did the teller give him? Justify your answer.
X = 31, Y = 63 satisfy the case of 0 ≤ Y < 100 as an expression.
What are algebraic expression?An algebraic expression in mathematics is an expression that consists of variables and constants and algebraic operations (addition, subtraction, etc.). Expressions are made up of concepts.
Assume Kaimi was supposed to be paid X dollars Y cents (0 ≤ Y ≤ 100)
But the teller gave him Y dollars X cents.
Thus kaimi has 100Y + X cents.
A nickel is worth 5 cents.
Hence, after buying the piece of candy for a nickel, Kaimi would be left with 100Y + X - 5 cents.
This is twice his paycheck:
⇒ 100Y + X - 5 = 2(100X + Y)
⇒ 100Y + X - 5 = 200X + 2Y
⇒ 98Y - 199X = 5
199 = 98 × 2 + 3 ⇒ 3 = 199 - 98 × 2
98 = 3 × 32 + 2 ⇒ 2 = 98 - 3 × 32
3 = 2 × 1 + 1 ⇒ 1 = 3 - 2 × 1
2 = 1 × 2 + 0 ⇒ ged(199, 98) = 1
1 = 3 - 2 × 1
= 3 - (98 - 3 × 32) × 1 [∵ 2 = 98 - 3 × 32]
= 3 - 98 × 1 + 3 × 32
= 3 × 33 - 98 × 1
= (199 - 98 × 2) × 33 - 98 × 1 [∵ 3 = 199 - 98 × 2]
= 199 × 33 - 98 × 67
⇒ 1 = 199 × 33 - 98 × 67
⇒ 5(1) = 5 (199 × 33 - 98 × 67)
⇒ 5 = 199(165) - 98(335) [∵ 5 ×33 = 165, 5 × 67 = 335]
⇒ 199(165) - 98(335) = 5
⇒ 98(-335) - 199(-165) = 5
Hence, (X,Y) = (-165, -335) is a solution to 98Y - 199X = 5
But it is required that 0 ≤ Y < 100
Now since it is the difference of two quantities, 98Y and 199X, that is a constant, 5, either both of these quantities will increase simultaneously or both will decrease simultaneously.
Hence, either both X, Y will increase or both, X, Y will decrease.
To bring Y = -335 in the range of 0 ≤ Y < 100, it needs to be increased.
Hence, both X, Y will increase.
X will increase by the absolute value of the coefficient of Y and vice-versa. Hence, X will increase by 98 and Y will increased by 199 to give
(X, Y) = (-165 + 98, -335 +199) = (-67, -136)
Still, it is not the case that 0 ≤ Y < 100
Hence, again X will increase by 98 and Y will increase by 199 to give
(X, Y) = (-67 +98, -136 +199) = (31, 63)
Now, it is the case that 0 ≤ Y = 63 < 100
∴ X = 31, Y = 63
Note that the increasing X again by 98 and Y by 199 will violate
0 ≤ Y < 100. Hence, this is the unique solution.

It is assumed that the test results for a class follow a normal distribution with a mean of 78 and a standard deviation of 36. If you know that a student's grade is greater than 72, what is the probability that it is greater than 84
Answer: 0.4337
Step-by-step explanation:
Let X represents the test results for a class that follow a normal distribution .
Given: Mean \(\mu=78\), Standard deviation \(\sigma=36\)
Then, the probability that it is greater than 84 will be
\(P(X>84)=P(\dfrac{X-\mu}{\sigma}>\dfrac{84-78}{36})\\\\=P(Z>0.167)\ \ \ [Z=\dfrac{X-\mu}{\sigma}]\\\\=1-P(Z<0.167)\\\\=1-0.5663=0.4337\ [\text{By p-value table}]\)

mega mart sells a large 5kg cake for $2500 while a 2kg chocolate cake cost $1200 what is the cheapest price sam would payfor 10kg of cake for the party
The cheapest price Sam would pay for 10kg of cake for the party is $5000 from Mega Mart.
To find the cheapest price Sam would pay for 10kg of cake for the party, we need to compare the prices of the available cakes and determine the most cost-effective option.
At Mega Mart, a 5kg cake costs $2500.
Therefore, the price per kilogram for this cake is:
Price per kilogram at Mega Mart = $2500 / 5kg = $500/kg.
At the same time, a 2kg chocolate cake costs $1200.
So, the price per kilogram for this cake is:
Price per kilogram for the chocolate cake = $1200 / 2kg = $600/kg.
Now, let's calculate the total price for 10kg of cake from each option:
Total price at Mega Mart for 10kg = $500/kg \(\times\) 10kg = $5000.
Total price for 10kg of chocolate cake = $600/kg \(\times\) 10kg = $6000.
Comparing the two options, we see that the Mega Mart cake is the more cost-effective choice.
Sam would pay a total of $5000 for 10kg of cake from Mega Mart, whereas the chocolate cake would cost $6000 for the same quantity.
Therefore, the cheapest price Sam would pay for 10kg of cake for the party is $5000 from Mega Mart.
In summary, Sam would pay the cheapest price of $5000 to purchase 10kg of cake for the party from Mega Mart.

The length of time that it will take for each of the workout sessions would be: Plan A = 1.5 hours, and Plan B = 0.5 hours.
What would be the length of the sessions?The length of the sessions can be obtained by first obtaining drawing a system of equations for the two cases. On Wednesday, we can represent the sessions as follows:
2A + 12B = 9 hours
On Thursday, we would have
5A + 3B = 9 hours
2A + 12B = 9 Eqn 1
5A + 3B = 9 Eqn 2
Multiply equation 2 by -4
2A + 12B = 9
-20A - 12B = -36
2A - 20A = 9 -36
-18A = -27
Divide both sides by -18
A = 1.5 hours
For B, substitute A in the first equation
2(1.5) + 12B = 9
3 + 12B = 9
12B = 9 - 3
12B = 6
