Answer:
182
Step-by-step explanation:
You can start by realizing that 14 is 7*2, and that that is already a common multiple, meaning that you can forget about 7 entirely. Now, because 13 is prime, the least common multiple of 13 and 14 will just be 13*14=182. Hope this helps!

Find the sum of the first 700700700 terms in the sequence.
Answer:
492,800
Step-by-step explanation:
Given ith term of an arithmetic sequence as shown:
ai = a(i-1)+2
and a1 = 5
When i = 2
a2 = a(2-1)+2
a2 = a1+2
a2 = 5+2
a2 = 7
When i = 3
a3 = a(3-1)+2
a3 = a2+2
a3 = 7+2
a3 = 9
It can be seen that a1, a2 and a3 forms an arithmetic progression
5,7,9...
Given first term a1 = 5
Common difference d = 7-5= 9-7 = 2
To calculate the sum of the first 700 of the sequence, we will use the formula for finding the sum of an arithmetic sequence.
Sn = n/2{2a1+(n-1)d}
Given n = 700
S700 = 700/2{2(5)+(700-1)2}
S700 = 350{10+699(2)}
S700 = 350{10+1398}
S700 = 350×1408
S700 = 492,800
Therefore, the sum of the first 700 terms in the sequence is 492,800
Final answer:
To calculate the sum of the first 700 terms of the arithmetic sequence, we apply the arithmetic series sum formula using the number of terms (700), the first term (5), and the common difference (2), resulting in a sum of 492800.
Explanation:
To find the sum of the first 700 terms of an arithmetic series, we use the formula for the sum of an arithmetic series: S = (n/2)(a1 + an), where n is the number of terms, a1 is the first term, and an is the last term. Given that a1 is 5, and the common difference d is 2, we can calculate the nth term (an) using the formula for the nth term of an arithmetic sequence: an = a1 + (d)(n - 1).
We know n = 700, d = 2, and a1 is 5. Thus, an = 5 + 2(700 - 1) = 5 + 2(699) = 5 + 1398 = 1403. The sum can then be calculated as S = (700/2)(5 + 1403) = 350(1408) = 492800.
Therefore, the sum of the first 700 terms of the arithmetic sequence is 492800.

at high school 40% of the students buy yearbooks. you select 6 students at random. Find P(exactly two buy yearbooks) and P(at least two buy yearbooks). Explain.
Answer:
P(exactly two buy yearbooks) = 0.31104
P(at least two buy yearbooks) = 0.76672
Step-by-step explanation:
We are given that at high school 40% of the students buy yearbooks.
You select 6 students at random.
The above situation can be represented through binomial distribution;
[tex]P(X = r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r};x=0,1,2,3,.......[/tex]
where, n = number trials (samples) taken = 6 students
r = number of success
p = probability of success which in our question is probability that
students buy yearbooks, i.e; p = 0.40
Let X = Number of students who buy yearbooks
So, X ~ Binom(n = 6, p = 0.40)
(a) Now, Probability that exactly two buy yearbooks is given by = P(X = 2)
P(X = 2) = [tex]\binom{6}{2} \times 0.40^{2} \times (1-0.40)^{6-2}[/tex]
= [tex]15\times 0.40^{2} \times 0.60^{4}[/tex]
= 0.31104
(b) Probability that at least two buy yearbooks is given by = P(X [tex]\geq[/tex] 2)
P(X [tex]\geq[/tex] 2) = 1 - P(X = 0) - P(X = 1)
= [tex]1- \binom{6}{0} \times 0.40^{0} \times (1-0.40)^{6-0}-\binom{6}{1} \times 0.40^{1} \times (1-0.40)^{6-1}[/tex]
= [tex]1- (1 \times 1 \times 0.60^{6})-(6 \times 0.40^{1} \times 0.60^{5})[/tex]
= 1 - 0.04666 - 0.18662
= 0.76672
Rosario was able to get a great interest rate on her house. She financed $150,000 for 15 years with an interest rate of 2.75%
When she pays off her mortgage, how much will she have spent in all ?
To calculate the total amount spent on a mortgage, multiply the monthly payment by the total number of months. For a $150,000 loan at an interest rate of 2.75% and a 15-year term, the total amount spent is approximately $181,884.60.
Explanation:To calculate the total amount spent on a mortgage, we need to find the monthly payment and multiply it by the total number of months. Using the formula for the monthly payment of a mortgage, we can calculate that the monthly payment for a $150,000 loan with an interest rate of 2.75% and a term of 15 years is approximately $1,010.47. Multiplying this monthly payment by the total number of months (15 years * 12 months per year) gives us the total amount spent, which is approximately $181,884.60.
what is the general solution to the differential equation dy/dx= cos(8x)/cos(4y) ?
A. sin =(4y) - sin(8x) = C
B. sin (4y) - 2 sin(8x) = C
C. 2 sin(4y) - sin(8x) = C
D. 2 tan(4y) - sin(8x) = C
Answer:
2sin4y - sin8x = K (C)
Step-by-step explanation:
Given the differential equation
dy/dx= cos(8x)/cos(4y)
This can be solved by using the variable separable method.
Step 1;
Separate the variables
Cos4ydy = cos 8xdx
step 2:
Integrate both sides of the equation
∫cos4y dy = ∫cos8x dx
sin4y/4 = sin8x/8
Step 3:
Add constant of integration to the side containing x variable
sin4y/4 = sin8x/8+ C
Taking sin8x to the other side we have:
sin4y/4-sin8x/8 = C
Multiplying through by 8:
2sin4y - sin8x = 8C
2sin4y - sin8x = K (where K = 8C )
To solve the given differential equation we have apply variable separation method.
The correct option is (c) 2 sin(4y) - sin(8x) = C.
Variable separation:In mathematics, variable separation method used to calculate the partially and ordinary differential function in which we rewrite the equation so that two variable occurs on two side.
Given:
The given differential equation is as follows,
[tex]\dfrac{dy}{dx}=\dfrac{\cos(8x)}{\cos(4y)}[/tex]
How to calculate the Separate the variable?Separate the variable.
[tex]\cos 4y \:dy =\cos 8x\:dx\\[/tex]
Integrate both side of the equation.
[tex]\int \cos4y dy = \int \cos8x dx\dfrac {1}{4}\sin4y = \dfrac {1}{8}\sin8x\\\dfrac {1}{4}\sin4y-\dfrac {1}{8}\sin8x=C\\2\sin4y - \sin8x = 8C[/tex]
Thus, the correct option is (c) 2 sin(4y) - sin(8x) = C.

A.) state the linear regression function that estimates the number of new homes available at a specific price.
B.) state the correlation Coefficient of the data, and explain what it means in the context of the problem
Answer:
Y = -0.79X + 249.86
R = -0.9543
Step-by-step explanation:
Sale Price :160 | 180 | 200 | 220 | 240 | 260 | 280
New home : 126 | 103 | 82 | 75 | 82 | 40 | 20
Calculate the Linear regression equation :
Using the linear regression calculator :
The linear regression equation is :
Y = -0.79X + 249.86
The correlation Coefficient 'R' measures the strength of statistical relationship between the relative movement of two variables. The The value of R is -0.9543 in the question above.
This is a strong negative correlation, which means that high sales price of homes scores correlates with low number of new homes scores (and vice versa). Homes with high sales price have fewer number of new homes.
The correct answer to the given table based on the linear regression is:
Y = -0.79X + 249.86R = -0.9543What is Correlation Coefficient?This refers to the number between -1 and +1 where the interdependence of two variables are shown.
Hence, based on the given table:
Sale Price :160 | 180 | 200 | 220 | 240 | 260 | 280
New home : 126 | 103 | 82 | 75 | 82 | 40 | 20
To find the Linear regression equation :
Y = -0.79X + 249.86
R= -0.9543
Hence, we can see that the correlation coefficient "R" is used to show the statistical relationship between the two variables.
As a result of the strong negative correlation, then there would be higher prices for homes and lower number of new homes.

0.55 hours
1.1 hours
5 hours
2.2 hours
Answer:
5 Hours
Step-by-step explanation:
Assuming their time is cut in half (roughly), you could do 1 + 2 + 2 = 5
It would take 1.1 hours for all working together, option B is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
We use the formula 1 / (time taken by all three to complete the job) = (1 / time taken by Laine) + (1 / time taken by Leslie) + (1 / time taken by Lance)
Plugging in the values given in the question, we get:
1 / (time taken by all three) = (1 / 2) + (1 / 4) + (1 / 5)
To simplify this equation, we first find a common denominator, which is 20.
Then we can rewrite the fractions:
1 / (time taken by all three) = (10 / 20) + (5 / 20) + (4 / 20)
1 / (time taken by all three) = 19 / 20
Multiplying both sides by 20, we get:
time taken by all three = 20 / 19
Hence, it would take 1.1 hours for all working together,

Answer:
The correct option is c,$36.60
Step-by-step explanation:
The key to solving this question lies around measurement conversion,specifically converting grams into its equivalence in kilograms.
1000 grams equal one kilogram
9 grams=9/1000 kg
9 grams=0.009 kg
70 grams=70/1000 kg
70 grams=0.07 kg

Jacques pays=$600*0.07=$42
Jacques pays $36.60 more ($42-$5.4) than Julie paid
Option is wrong because that was what Julie paid
Option D is wrong because that was what Jacques paid
Option B is obviously wrong
