At a local company, the ages of all new employees hired during the last 10 years are normally distributed. The mean age is 38 years old, with a standard deviation of 10 years. Find the percent of new employees that are no more than 30 years old. Round to the nearest percent.
Answer:
P = 21%
Step-by-step explanation:
We look for the percentage of employees who are not more than 30 years old.
This is:
[tex]P = \frac{x}{n} *100\%[/tex]
Where x is the number of new employees who are not over 30 years old and n is the total number of new employees.
We do not know the value of x or n. However, the probability of randomly selecting an employee that is not more than 30 years old is equal to [tex]P = \frac{x}{n}[/tex]
Then we can solve this problem by looking for the probability that a new employee is not more than 30 years old.
This is:
[tex]P(X< 30)[/tex]
Then we find the z-score
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
We know that:
μ = 38 years
[tex]\sigma = 10[/tex] years
So
[tex]Z = -0.8[/tex]
Then
[tex]P (X<30) = P (\frac{X- \mu}{\sigma} < \frac{30-38}{10})\\\\P (X<30) = P(Z<-0.8)[/tex]
By symmetry of the distribution
[tex]P(Z<-0.8)=P(Z>0.8)[/tex]
Looking in the normal standard tables
[tex]P(Z>0.8)=0.211[/tex]
Finally P = 21%

Answer:
Broker Q’s commission will be $13.56 less than Broker P’s
Step-by-step explanation:
Answer:
Broker Q will give Diana the better deal by $13.56.
Step-by-step explanation:
Diana wants to purchase a par value $1000 corporate bond. Broker P charges 4.4% of the market value, so the commission would be $46.06008 per bond. On the other hand, Broker Q would only charge $32.50 for each bond; due to this, the difference would be $13.56 in favor of Broker Q.

Complete the steps to factor 12x3-9x2+8x-6 by grouping
Answer:
(4x−3)(3x²+2)
Step-by-step explanation:
Factor 12x3−9x2+8x−6
12x3−9x2+8x−6
=(4x−3)(3x2+2)
The factored form of the expression 12x³ - 9x² + 8x - 6 by grouping is (3x² + 2)(4x - 3).
To factor the expression 12x³ - 9x² + 8x - 6 by grouping, we can group the terms in pairs and factor out the common factors.
Step 1: Group the terms in pairs
(12x³ - 9x²) + (8x - 6)
Step 2: Factor out the greatest common factor from each pair
3x²(4x - 3) + 2(4x - 3)
Step 3: Notice that both terms now have a common factor of (4x - 3)
(3x² + 2)(4x - 3)
Therefore, the factored form of the expression 12x³ - 9x² + 8x - 6 by grouping is (3x² + 2)(4x - 3).

How many solutions does the system have?
{ y = -2x + 4
{ 7y = -14x + 28
Choose 1 answer:
A. Exactly one solution
B. No solutions
C. Infinitely many solutions
Answer:
{x,y} = {-2,2}
Step-by-step explanation:
Solve equation [2] for the variable y
7y = 7x + 28
y = x + 4
Plug this in for variable y in equation [1]
-8x + 4•(x +4) = 24
-4x = 8
Solve equation [1] for the variable x
4x = - 8
x = - 2
By now we know this much :
x = -2
y = x+4
Use the x value to solve for y
y = (-2)+4 = 2
Solution :
{x,y} = {-2,2}
and this intersects at only one point so your answer is A
The correct answer is: [tex]\[ \text{C. Infinitely many solutions} \][/tex].
To determine the number of solutions for the given system of equations, let's analyze it:
1. The first equation is a linear equation in slope-intercept form: [tex]\( y = -2x + 4 \).[/tex]
2. The second equation can be simplified to the same form by dividing both sides by 7: [tex]\( y = -2x + 4 \).[/tex]
Comparing the two equations, we can see that they represent the same line. In other words, the equations are equivalent.
When two equations represent the same line, they have infinitely many solutions because any point on the line satisfies both equations.

The length of a rectangle is 7 centimeters less than its width. What are the dimensions of the rectangle if its area is 144 square centimeters?
Answer:
Width = 16 cm
Length = 9 cm
Step-by-step explanation:
Width = x cm
Length = x - 7
Area = 144 cm²
x(x - 7) = 144
x² - 7x = 144
x² - 7x - 144 = 0
(x - 16)(x + 9) = 0
x = 16 or x = -9 (rejected)
Width = 16 cm
Length = 16 - 7 = 9 cm
The width is determined to be 16 cm, and the length is 9 cm.
The student is asking for the dimensions of a rectangle given an area of 144 square centimeters and a length that is 7 centimeters less than its width. To find the dimensions, we can let the width be represented by w and the length by w - 7 (since the length is 7 centimeters less than the width). The area of a rectangle is calculated by multiplying the length by the width, which in this equation would be w(w - 7). We can set this equal to the given area of 144 square centimeters and solve for w.
Setting up the equation: w(w - 7) = 144. This simplifies to w^2 - 7w - 144 = 0.
To solve for w, we need to factor the quadratic equation, which results in (w - 16)(w + 9) = 0. The width can be 16 cm because it must be a positive value. Subsequently, the length is 16 - 7 = 9 cm.
Therefore, the dimensions of the rectangle are 16 cm in width and 9 cm in length.
Given these two terms in a geometric sequence, find the recursive formula.
a1=4
a6=31104
Answer:
[tex]\boxed{ a_{n} = 6a_{n-1}}[/tex]
Step-by-step explanation:
Step 1. Determine the common ratio
The formula for the nth term of a geometric sequence is
aₙ = a₁rⁿ⁻¹
Data:
a₁ = 4
n = 6
a₆ =31 104
Calculation:
31 104 = 4r⁵
r⁵ = 7776
[tex]r = \sqrt [5]{7776}[/tex]
r = 6
aₙ = 4(6)ⁿ
Step 2. Determine the recursive formula.
aₙ = 4(6)ⁿ
aₙ₋₁ = 4(6)ⁿ⁻¹
[tex]\dfrac{a_{n}}{{a_{n-1}}} = \dfrac{4(6)^{n} }{4(6)^{n-1}} = 6\\\\a_{n} = 6a_{n-1}[/tex]
The recursive formula for the series is [tex]\boxed{ a_{n} = 6a_{n-1}}[/tex]

Q3: 17 (the average between the middle terms of second half of the data)
Max: 19
Outlier: 42
Only option D shows
Answer:
The last box plot
Step-by-step explanation:
A box plot is simply a graphical representation of the 5 number summary of a data set;
The minimum, first quartile, median, third quartile, and the maximum
in that order.
We can therefore arrange our given data set from the least to the greatest value;
1, 2, 4, 7, 8, 10, 11, 12, 14, 16, 18, 19, 42
The value 42 is an outlier since it is more extreme than the rest of the values.
From our arrangement of the data values above, we can note the following;
The minimum value is 1
The maximum value is 19
42 is an outlier, will be represented by a dark circle
The box-plot that matches the above is the last one and is thus the correct modified box-plot for the data

A survey of 120 college students is conducted and the results displayed below show that 90 students have a smartphone, 45 have a tablet, and 10 have neither. Fill in the empty table cells in the two-way frequency table.
Smartphone No Smartphone Total
Tablet 45
No Tablet 10
Total 90 120
What is the probability (rounded to the nearest whole percent) that a randomly selected college student has a tablet but not a smartphone?
A.) 20%
B.) 5%
C.) 17%
D.) 67%
Answer:
C) 17%
Step-by-step explanation:
Table: has tablet | no tablet | total
has phone | 25 65 90
no phone | 20 10 30
total | 45 75 120
No tablet total: 120 - 45 = 75
No phone total: 120 - 90 = 30
No tablet phone: 75 - 10 = 65
No phone tablet: 30 - 10 = 20
Both: 45 - 20 = 90 - 65 = 25
-------------------------------------------------------------------------
So out of 120 students, 20 of them will have a tablet but no phone. 20/120 = 1/6 = 0.16666... ≈ 17%

A garden table and a bench cost $741 combined. The garden table costs $91 more than the bench. What is the cost of the bench?
Answer:
bench: $416; table: $325.
Step-by-step explanation:
Let t and b represent the costs of the table and bench respectively. Then:
t + b = $741, and t = b + $91.
Substituting b + $91 for t in the first equation, we get:
b + $91 + b = $741
Then 2b = $741 - $91, or 2b = $650
Then the bench costs $325 and the table ($325 + $91), or $416.

Yes, it is a right triangle.
Step-by-step explanation:
Look at the points:
(1, 1), (1,4)
(1,4), (4,4)
(4,4), (1,1)
Find the slope between each point: In respective order, the first one is undefined, the second one has a slope of zero, and the third has a slope of 1. Because undefined slope is completely vertical (parallel to the y axis, and the slope of 0 is completely horizontal (parallel to the x axis), they are perpendicular (as it is transitive since the x axis is perpendicular to the y axis). Therefore, we know that anything that is perpendicular created a right angles', and thus, the any triangle with a right angle is a right triangle.
