help me please
Answer:
d = 10.5, a₁ = - 3.5
Step-by-step explanation:
The n th term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₂ = 7 and a₄ = 28 , then
a₁ + d = 7 → (1)
a₁ + 3d = 28 → (2)
Subtract (1) from (2) term by term to eliminate a₁
2d = 21 ( divide both sides by 2 )
d = 10.5 ← common difference
Substitute d = 10.5 into (1)
a₁ + 10.5 = 7 ( subtract 10.5 from both sides )
a₁ = - 3.5 ← first term

Answer:
x= 10
Step-by-step explanation:
8x+30=110
8x+30-30=110-30
8x=80
8x/8=80/8
x=10
Answer:
x=10
Step-by-step explanation:
Vertical angles are always congruent, those to angles are vertical angles so they are congruent.
Set them equal to each other:
110=8x+30 subtract 30 from both sides
80=8x divide by 8 on both sides
x=10

Which statement about stratified random sampling is true? A stratified random sample is a combination of simple random samples selected from each of several strata. A stratified random sample is formed by selecting one stratum from a simple random sample of the population. A selection of every 3rd person from an alphabetical list of a population forms a stratified random sample. A stratified random sample consists of choosing several strata, and each stratum is representative of the entire population.
Answer:
A. A stratified random sample is a combination of simple random samples selected from each of several strata.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Convenience sampling.
3. Systematic sampling.
4. Cluster sampling.
5. Stratified sampling.
Stratified random sampling can be defined as a method of sampling that involves dividing a population into smaller groups known as strata.
In stratified random sampling, the strata are formed based on member's shared characteristics (e.g female or male, occupation, education) or attribute (e.g black or white).
Hence, the statement about stratified random sampling which is true is that, a stratified random sample is a combination of simple random samples selected from each of several strata.

Your new job is at the custom t shop, where t-shirts are printed to order. For each order, custom t shop charges $8.00 per shirts plus a one time set up fee for $15.00
Answer:
Price = 15+8t
Step-by-step explanation:
Your new job is at the custom t shop, where t-shirts are printed to order.
For each order, custom t shop charges $8.00 per shirts plus a one time set up fee for $15.00.
Here, $15 remain fix and $8 increases with number of shirts.
Price = 15+8t
Hence, the price of the t-shirts is "15+8t".
It takes 6 workers from the Fast Movers Company 10 hours to unload 6 trucks. It takes 10 workers from the Careful Movers Company 8 hours to load 2 trucks. How long would it take 4 workers from the Fast Movers Company and 8 workers from the Careful Movers Company to unload 8 trucks?
Answer:
The time it would take 4 workers from the Fast Movers Company and 8 workers from the Careful Movers company to unload 8 trucks is 13 hours and 20 minutes
Step-by-step explanation:
The time it takes 6 workers from the Fast Movers Company to unload 6 trucks = 10 hours
The time it takes 10 workers from the Careful Movers Company to load 2 trucks = 8 hours
Therefore, when 1 worker of the Fast Movers Company is unload 1 truck each of the 6 trucks it takes 10 hours
Which gives the time for 1 worker of the Fast Movers Company is unload 1 truck = 10 hours, which gives;
10 worker hours per truck or 10 worker·h/(truck)
Similarly we have;
The time it takes 10 workers of the Careful Movers Company to load 2/2 = 1 truck = 8/2 = 4 hours
Therefore, the time it would take 1 worker of the Careful Movers Company to load 1 truck = 10 × 4 hours = 40 hours, which gives;
40 worker·h/(truck)
Let "t" represent the time it would take 4 workers from the Fast Movers Company and 8 workers from the Careful Movers Company to unload 8 trucks
We have;
[tex]\dfrac{4 \ workers \times t }{\left (\dfrac{10 \ worker \cdot hour}{truck} \right ) } + \dfrac{8 \ workers \times t }{\left (\dfrac{40 \ worker \cdot hour}{truck} \right ) } = 8 \ trucks[/tex]
Which can be simplified as follows;
[tex]\dfrac{4 \ trucks \times t }{10 \cdot hour} + \dfrac{8 \ trucks \times t }{40 \cdot hour} = t \times \left ( \dfrac{4 \ trucks }{10 \cdot hour} + \dfrac{8 \ trucks }{40 \cdot hour} \right ) = 8 \ trucks[/tex]
[tex]t = \dfrac{8 \ trucks}{\left ( \dfrac{4 \ trucks }{10 \cdot hour} + \dfrac{8 \ trucks }{40 \cdot hour} \right ) } = \dfrac{8 \ trucks}{\left ( \dfrac{3 \ trucks }{5 \ hour} \right ) } = \dfrac{5 \ hour\times 8 \ trucks}{3 \ trucks } \right ) } = \dfrac{40}{3} \ hours[/tex]
t = 40/3 hours = 13 hours and 20 minutes
The time it would take 4 workers from the Fast Movers Company and 8 workers from the Careful Movers company to unload 8 trucks = 13 hours and 20 minutes

Maria creates a sequence of integers where the first and second terms are both 1. At each step she adds the last two terms she has obtained. If the sum is less than 9, then she enters that sum as her new term. Otherwise she subtracts 8 from the sum and records that. Her sequence therefore starts 1, 1, 2, 3, 5, 8, 5, 5, . . . Find the 2020th term in the sequence.
Answer:
The 2020th term is 3
Step-by-step explanation:
Recursive Sequence
We are given a recursive and conditional sequence where each term depends on two previous terms and a rule.
Each term is the sum of the two previous terms. But if that sum exceeds 8, then 8 is subtracted.
The first terms are, therefore:
1, 1, 2, 3, 5, 8, 5, 5, 2, 7, 1, 8, 1, 1, 2, 3, 5, 8, 5, 5, 2, 7, 1, 8, ....
Note the sequence repeats itself at term 13, that is:
a13=a1, a14=a2, a15=a3 and so on.
To find any given term, it's just a matter of calculating the remainder of that number of the term divided by 12.
For example, the term number 100 is calculated by dividing 100/12=8 (only the integer part).
Since 8*12=96, the remainder is 100-96=4
Thus, a100=a4=3
The term 2020 is calculated now:
2020/12 = 168 (integer only)
168*12=2016
The remainder is 2020-2016=4, thus
a2020 = a4 = 3
The 2020th term is 3

. A flagpole is standing in front of City Hall. Percy, who is standing near the flagpole is 5' tall and casts a shadow 3' long. If the flagpole casts a shadow 36' long, how tall is the flagpole
Answer:
The flagpole is 60'(60 inches) tall
Step-by-step explanation:
A flagpole is standing in front of City Hall. Percy, who is standing near the flagpole is 5' tall and casts a shadow 3' long. If the flagpole casts a shadow 36' long, how tall is the flagpole
The formula is given as:
Height of percy/ Shadow of percy = Height of flagpole/Shadow of flagpole
Height of percy = 5 inches
Shadow of percy = 3 inches
Height of flagpole = ??
Shadow of flagpole =36 inches
= 5/3 = x/36
Cross Multiply
3 × x = 36 × 5
3x = 36 × 5
x = 36 × 5/3
x = 60 inches
Therefore, the flagpole is 60'(60 inches) tall.

Identify the correct corresponding parts
Answer:
The correct corresponding part is;
[tex]\overline {CB}[/tex] ≅ [tex]\overline {CD}[/tex]
Step-by-step explanation:
