Based on the calculations on this arithmetic sequence, the value of the first term is equal to -8.
What is an arithmetic sequence?An arithmetic sequence can be defined as a series of real and natural numbers in which each term differs from the preceding term by a constant numerical quantity.
How to calculate an arithmetic sequence?Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:
aₙ = a₁ + (n - 1)d
Where:
d represents the common difference.a₁ represents the first term of an arithmetic sequence.n represents the total number of terms.Given the following data:
Tenth term (a₁₀) = 30.
Common difference = 2.
Substituting the given parameters into the formula, we have;
10 = a₁ + (10 - 1)2
10 = a₁ + (9)2
10 = a₁ + 18
a₁ = 10 - 18
First term, a₁ = -8.

What will be the location of the y value of R' after using the translation rule (x + 4, y - 7), if the pre-image R is located at ( -17, -3)
Using translation concepts, the y-coordinate of R' will be of -10.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, the rule is given by:
(x,y) -> (x + 4, y - 7)
y -> y - 7 means that for the image, the 7 is subtracted from the y-coordinate of the pre-image. The y-coordinate of R is of -3, -3 -7 = -10, hence the y-coordinate of R' will be of -10.

The width rectangle is three less than twice its length. If the area of the rectangle is 193 cm² what is the length of the diagonal?
Answer:
Step-by-step explanation:
Givens
Let the Length = L
Let the width = w
w = 2*L - 3
Area = L * w
Area = 193
Solution
Area = 193
193 = L*(2L - 3)
193 = 2L^2 - 3L Subtract 193 from both sides.
2L^2 - 3L - 193 = 0
You have to use the quadratic formula get the answer. Without going through all all that, I will tell you that the only value you can use for L is 10.6
L = 10.6
w = 2* 10.6 - 3 = 18.4
But you want the diagonal. Use the Pythagorean Theorem to get it.
Diagonal^2 = L^2 + w^2
Diangonal^2 = 10.6^2 + 18.4^2
Diagonal^2 = 450.92 Take the square root of both sides
√diagonal^2 = √450.92
Answer
The diagonal is 21,23
Theoretically, If the spinner is spun 400 times, how many times would you expect to get blue?
Based on the experiment, if the spinner is spun 400 time, how many times would you expect to get blue.
The number of times that blue will be expected will be 100 times.
What will be the probability of getting a blue?It should be noted that from the information given, the spinner is divided into four equal sections labeled yellow, green, red, and blue.
It simply means that each color has a 1/4 chance for each scenario.
Therefore, the number of times that blue will be expected will be:
= 1/4 × 400
= 100 times
Therefore, the number of times that blue will be expected will be 100 times.

(1’^0)^1 d) (1v0’)^(0v1) Logic statements
We need to know about logic statements to solve this problem. The solution of the logic statements are 0 and 1 respectively.
Logical operators are used to form logical statements, logical operators compute result based on boolean values true and false or binary 1 and 0. The common logical operators are AND and OR. AND is represented by ^ symbol and OR is represented by v symbol, ' means negation of the value, which means that true becomes false and vice versa. For AND operator, it works like multiplication, 0 and 1 yield 0, 1 and 1 yields 1 and 0 and 0 yields 0. For OR operator it works like addition, 0 and 1 yields 1, 1 and 1 yields 1 and 0 and 0 yields 0. For the logical statements given in the question we need to first compute the logical statement inside the bracket and then compare the inner result with the outer value.
(1'^0)^1 =(0^0)^1=0^1=0
(1v0')^(0v1)=(1v1)^(0v1)=1^1=1
Therefore we found the values of the logical statements to be 0 and 1 respectively.

a. if the data are normally distributed with standard deviation $390, find the percentage of vacationers who spent less than $1,200 per 12-day vacation. round to the nearest hundredth of a percent.
The percentage of vacationers who spent less than $1,200 per 12-day vacation is 7.78%.
What is normal distribution?The normal distribution, also recognized as that of the Gaussian distribution, would be a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data far away from the mean. The normal distribution is represented graphically as a "bell curve."
Now, according to the question;
The formula for finding the z-score is;
z = (x - μ)/σ
where,
x is the score
μ is the mean
σ is the standard deviation.
Summer vacation costs $1,755 for the average local family.
The distribution is normal, with a standard deviation of $390.
We need to figure out what percentage of families took vacations less than $1200.
The mean is $1,755
∴ μ = $1,755
∵ The standard deviation is $390
∴ σ = 390
∵ The vacation cost is under $1200
∴ x = $1200
Substitute the values in the formula of z score.
z-score = (1200 - 1,755)/390 = -1.42
Use the negative normal distribution table of z
P(z < 1,200) = 0.07782
P(x < 1,200) = P(z < 1,200)
P(x < 1,200) = 0.07782
P(x < 1,200) = 7.78%
Therefore, the percentage of vacationers who spent less than $1,200 per 12-day vacation is 7.78%.

Answer:
[tex]12 > x[/tex]
Step-by-step explanation:
[tex]20 > .75x + 4[/tex]
Is the equation you need to set up.
Then you want to subtract four from both sides ehich ends up giving you
[tex]16 > .75x[/tex]
Then divide 16 by 4 (this gives you a fourth) you get four
Then multiple 4 by 3 to get .75 of 16 which is 12
Hope this helps!
If yoy have any other questions feel free to ask!
Answer:
Tanner can play 20 games in the arcade and will have 50 cents left over.
Step-by-step explanation:
20 = 4.50 + 0.75x
Subtract 4.5 from both sides.
15.5 = 0.75x
Plug in numbers for x until it is equal more that 15.5
x = 20

The length and breadth of a land are x m and y m respectively . If perimeter of the land is 420 m, then
a. Write the equation which represent perimeter of land
b. If length of the land is 120 m, then find the breadth
Answer:
90 m
Step-by-step explanation:
a. Perimeter = 2( length + breadth) 2(x + y)
Answer: Perimeter: 2(x + y) = 420
or 2x + 2y = 420
Using the values given
b.
2x + 2y = 420 (perimeter p= 420)
2(120) + 2y = 420 (length x = 120)
240 + 2y = 420
2y = 420 - 240 = 180 (subtract 240 on both sides)
y = 190/2 = 90 m

A percentage is a number or ratio expressed as a fraction of 100.
From the given information:
a hospital day staff consists of 25 registered nurses, 75 unlicensed assistants, five phlebologists, six receptionists and office staff, and 45 physicians. one summer day the staff was at only 68% strength.
Then
Total number of staff = 25+75+5+6+45
Total number of staff = 156
Then
the staff was at strength = 68%
And then
Number of people working on that day = 68% of 156
And
Number of people working on that day = 68/100 *156
Number of people working on that day = 0.68*156

you buy tealight candles and mints as party favors for a babyshower.e tealight candles come in packs of 12 for $3.50. e mints come in packs of 50 for $6.25. whatis the least amount of money you can spend to buy the same number of candles and mints?
The least amount of money you can spend to buy the same number of candles and mints is $125.
The prime factorization of 12 and 15 is:
12= 2*2*3
15= 2*5*5
Now the factor of both appears in both number's factorization so least common multiple is:
LCM of 12 and 15 = 2*2*3*5*5=300
It is given that candies come in packs of 12 and mints in packs of 50.
Hence, the total quantity of packs of each thing is:
Candles: 300÷12=25
Mints: 300÷50=6
The least amount of money to be spent is:
25×$3.50 + 6×$6.25= $87.5 + $37.5= $125
Thus, the least amount of money you can spend to buy the same number of candles and mints is $125.

8 yard. How many yards of material does Jack have left?
Jack has left with the 19/8 yards fraction part of material.
What is Yards?In mathematics, yard is the unit of length. we can say that yard is the one of the measurement of length. Conversion of yard in various quantities is as below:
In inches :1 yard = 36 inches
In feet :1 yard = 3 feets
In meters :1 yard = 0.914 meters
For the question given,
If we have to find the remaining material that has been left we must find the difference between the two i.e. used and purchased material by simply subtracting them.
So, Material purchased = 3 yards
Material used = 5/8 yards
now, material left = Material purchased - material used
= 3 - 5/8
= 19/8 yards
Thus, Jack has left with the 19/8 yards material.
