Write an explicit formula for an, the n^th term of the sequence 22, 20, 18, ....
Answer:
[tex]a_n=a+(n-1)d[/tex]
Step-by-step explanation:
The given sequence is 22, 20, 18, ...
We need to find the explicit formula for an.
First term is 22
Second term = 20
Third term = 18
We can write the formula as :
[tex]a_n=a+(n-1)d[/tex]
Where
a is 22
d is common difference = 20-22 = -2
Forth term will be :
[tex]a_4=22+(4-1)(-2)\\\\=22-6\\\\=16[/tex]
Hence, the formula is [tex]a_n=a+(n-1)d[/tex].

45 people in a certain company can work together to finish a project in 15 days. For a project of the same workload, the
company decided to use 15 people. Assume all people have the same level of productivity.
In how many days can this project be completed?
SELECT ONLY ONE
5 days
10 days
22.5 days
45 days
Given:
45 people will accomplish the given task in 15 days.
To find:
Days taken by 15 people to complete the same task.
Solution:
Since, 45 people of a company can finish a work in 15 days
Therefore, 1 person can accomplish the task in days = [tex]15\times45[/tex]
= [tex]675[/tex] days
15 people will accomplish the same task in number of days = [tex]\frac{675}{15}[/tex]
= [tex]45[/tex]
Therefore, number of days taken by 15 people to accomplish the same task will be 45 days.

A DVD player costs a store $185 to purchase from the manufacturer. They mark the price of the DVD player up by 20% for profit. How much do they charge for the DVD player?
Answer:
$222
Step-by-step explanation:
$185 x 1.2 = $222
Answer:
222
Step-by-step explanation:
Hi! So marking up means to raise the price or increase it.
185 is the whole, a whole is 100
and we need to raise it by 20% so add these two together to get 120%, turn this into a decimal is 1.2, now to find and increase we multiply it by the original price.
1.2 x 185 = 222

Does the set of points represent a function? Explain.
Answer:
NO
Step-by-step explanation:
Recall: for a relation or a set of points to be a function, every x-value or input must have exactly one y-value or output.
From the given set of points, the x-value (inputs), -2, has two y-values (inputs), 1 and 3.
Therefore, the set of points does not represent a function.
Calculate the standard deviation of X for the probability distribution. (Round your answer to two decimal places.)
x 0 1 2 3
P(X = x) 0.1 0.5 0.1 0.3
Answer:
The standard deviation of the probability distribution is 1.02.
Step-by-step explanation:
Standard deviation of the distribution:
Square root of the sum of the difference squared between each value and the mean multiplied by its probability.
Mean:
Each value multiplied by its probability. So
[tex]E(X) = 0*0.1 +1*0.5 + 2*0.1 + 3*0.3 = 1.6[/tex]
Standard deviation:
[tex]\sqrt{V(X)} = \sqrt{0.1*(0-1.6)^2 + 0.5*(1-1.6)^2 + 0.1*(2-1.6)^2 + 0.3*(3-1.6)^2} = 1.02[/tex]
The standard deviation of the probability distribution is 1.02.
What is the original price of a pair of shoes if there is a 5% discount and the sale price is $47.03?
Answer:
$49.51
Step-by-step explanation:
100-5(the discount) =95%equate 95%=47.03 what about 100%(100%×47.03)÷95$49.51 ansThe original price of the shoes is $49.50.
What is the discount?The pricing scheme in which the cost of a thing (or service) is less than its marked price listed price is referred to as a "discount." Simply put, a discount represents a percentage off the advertised price. In consumer interactions, a discount is a type of product price reduction where customers have suggested a percentage of rebates on various goods to increase sales.
Given discount = 5%
sale price = $47.03
to find original price
discount is given by
Discount (percentage) = (List Price - Selling Price)/ List Price x 100
5% = 1 - SP/LP
SP/LP = 1 - 5%
47.03/LP = 1 - 5/100
LP = (47.03 x 100)/95
LP = $49.50
Hence the original price of the shoes is $49.50.

Allison designs fancy boxes to fill with chocolates. The boxes are in the shape of a right square pyramid as shown, where 8y represents the
length of one side of the base of the pyramid, and 5y represents the height of one triangular face of the pyramid.
8y
The large size box must be designed to have a volume of 1,000 cubic centimeters,
Create an equation that can be used to calculate the length of the base and height of the triangular face of the box. Enter your equation in
the first response box.
The requreid equation that can be used to calculate the length of the base and height of the triangular face of the box is:
8y ≈ 8.4 cm
5y ≈ 5.8 cm
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
The formula for the volume of a square pyramid is:
V = (1/3) * base area * height
In this case, the base of the pyramid is a square with a side length of 8y, so the base area is:
base area = (8y)² = 64y²
The height of each triangular face is given as 5y, so the total height of the pyramid is 2 * 5y = 10y.
Substituting these values into the formula for volume, we get:
1000 = (1/3) * 64y² * 10y
y ≈ 1.16
Therefore, the length of the base of the pyramid is:
8y ≈ 8.4
And the height of each triangular face is:
5y ≈ 5.8 cm
So the equation that can be used to calculate the length of the base and height of the triangular face of the box is:
8y ≈ 8.4 cm
5y ≈ 5.8 cm

8/17
15/17
15/8
8/15
Answer:
15/8
Step-by-step explanation:
Assuming you mean tan theta
Tan(theta) = opposite/adjacent
We know the adjacent side is 8 so the bottom of the fraction must also be 8
C: 15/8 is the only option that fits this criteria
The value of tangent of the angle θ, i.e., tan θ = 15/8.
Hence the correct option is c.
Given is a right triangle, with base = 8 units and the hypotenuse is 17 units,
The angle θ which is between the base and the hypotenuse,
We need to find the value of tangent of the angle θ, i.e., tan θ.
To find the value of tangent (tan) of the angle θ, we can use the definition of tangent in a right triangle.
The tangent of an angle in a right triangle is equal to the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
In this case, the base of the triangle is given as 8 units, and the hypotenuse is given as 17 units.
To find the length of the side opposite θ, we can use the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
Using this theorem, we can calculate the length of the side opposite θ:
(side opposite θ)² + (base)² = (hypotenuse)²
(side opposite θ)² + 8² = 17²
(side opposite θ)² + 64 = 289
(side opposite θ)² = 289 - 64
(side opposite θ)² = 225
side opposite θ = √225
side opposite θ = 15 units
Now that we have the lengths of the side opposite θ and the side adjacent to θ, we can calculate the tangent of the angle θ:
tan θ = (side opposite θ) / (base)
tan θ = 15 / 8
Therefore, the value of tangent (tan) of the angle θ is 15/8.
