Answer:
the real limits are;
Lower Real Limits = 249.5
Upper Real Limits = 250.5
Step-by-step explanation:
Given the data in the question;
1 minute being the smallest unit on the scale
so we say; 1/2 which 0.5 minutes which we will use to calculate pur real limits time;
given that; the first subject sleeps 250 minutes
so
Lower Real Limits will be;
Lower Real Limits will = 250 - 0.5 = 249.5
Also our Upper Real Limits will be;
Upper Real Limits = 250 + 0.5 = 250.5
Therefore; the real limits are;
Lower Real Limits = 249.5
Upper Real Limits = 250.5

Step-by-step explanation:
write the first six terms of the geometric sequence with the first term 6 and common ratio 1/3
Answer:
6, 2, 2/3, 2/9, 2/27, 2/81
Step-by-step explanation:
The nth term of a geometric progression is expressed as;
Tn = ar^n-1
a is the first term
n is the number of terms
r is the common ratio
Given
a = 6
r = 1/3
when n = 1
T1 = 6(1/3)^1-1
T1 = 6(1/3)^0
T1 = 6
when n = 2
T2= 6(1/3)^2-1
T2= 6(1/3)^1
T2 = 2
when n = 3
T3 = 6(1/3)^3-1
T3= 6(1/3)^2
T3= 6 * 1/9
T3 = 2/3
when n = 4
T4 = 6(1/3)^4-1
T4= 6(1/3)^3
T4= 6 * 1/27
T4 = 2/9
when n = 5
T5 = 6(1/3)^5-1
T5= 6(1/3)^4
T5= 6 * 1/81
T5 = 2/27
when n = 6
T6 = 6(1/3)^6-1
T6= 6(1/3)^5
T6= 6 * 1/243
T6 = 2/81
Hence the first six terms are 6, 2, 2/3, 2/9, 2/27, 2/81
at what value of x, the function 2x^3/3+2x^2-6x+4 is minimum
Answer:
x=1
Step-by-step explanation:
We are given that
[tex]\frac{2x^3}{3}+2x^2-6x+4[/tex]
We have to find the value of x for which function is minimum.
Differentiate w.r.t x
[tex]f'(x)=2x^2+4x-6[/tex]
Substitute f'(x)=0
[tex]2x^2+4x-6=0[/tex]
[tex]x^2+2x-3=0[/tex]
[tex]x^2+3x-x-3=0[/tex]
[tex]x(x+3)-1(x+3)=0[/tex]
[tex](x-1)(x+3)=0[/tex]
[tex]x=1,-3[/tex]
Again, differentiate w.r.t x
[tex]f''(x)=4x+4[/tex]
[tex]f''(1)=4(1)+4=8>0[/tex]
[tex]f''(-3)=4(-3)+4=-8<0[/tex]
Hence, the function is minimum at x=1

One angle of a triangle is three times larger as another. the measure of the third angle is 50 degrees more than that of the smallest angle. Find the measure of each angle.
Answer:
Smallest angle of triangle=26 degrees
Second angle of triangle =78 degrees
Third angle of triangle =76 degrees
Step-by-step explanation:
Let x be the smallest angle of triangle
Second angle of triangle=3x
Third angle of triangle=x+50
We know that
Sum of angles of triangle=180 degrees
Using the property
[tex]x+3x+x+50=180[/tex]
[tex]5x=180-50[/tex]
[tex]5x=130[/tex]
[tex]x=\frac{130}{5}[/tex]
[tex]x=26[/tex] degree
Smallest angle of triangle=26 degrees
Second angle of triangle =3(26)=78 degrees
Third angle of triangle =26+50=76 degrees
which of the following lines are parralell to x=7
Since x=7 is a vertical line, the slope is undefined. To find an equation that is parallel, the slopes must be equal. Since the slope is undefined, the slope of the parallel line is also undefined. However answer is x=4.
(SAT prep) find the value of x.
Answer:
140 degrees
Step-by-step explanation:
Ok, so angle in = angle out. This means there are 2 20 degree angles and the total angle of this line is 180 degrees and so 180 - 40 = 140.
Answer:
[tex]x=120[/tex]
Step-by-step explanation:
When two lines are parallel and intersected by a transversal, the alternate corresponding angles are supplementary (their sums equal 180). In the picture, the two parallel lines are intersected by the vertical lines. Then, one of the angles formed intersected again. This means that the sum of the two smaller angles, plus the alternate exterior angle is equal to 180. Hence the following equation can be formed;
[tex]x+20+40=180[/tex]
Simplify,
[tex]x+60=180[/tex]
Inverse operations;
[tex]x+60=180\\-60\\\\x=120[/tex]

Nicole can buy 3 pounds of Luce suppose an orchard for $4.95 or she can buy a 25 ounce bag of apples from the store for $3.79 which is the better deal?
9514 1404 393
Answer:
orchard apples are lower-cost
Step-by-step explanation:
3 pounds is 48 ounces, so the equivalent to the store offering might be about 24 ounces for $4.95/2 ≈ $2.48.
This is substantially less cost per ounce than 25 ounces for $3.79. (24 and 25 are very near, but $2.48 and $3.79 are not.)
Orchard apples are the better deal.
A server at a restaurant works 5 hours on a weekday and 8 hours on a weekend day. Use the expression to find the number of hours the server works on 4 weekdays and 2 weekend days.
Answer: 36 hours
Step-by-step explanation:
t = total hours
t = 5d + 8w
t = 5(4) + 8(2)

What does the statement “ The shortest distance between two points is the straight line between them” have to do with the Triangle Inequality Conjecture?
Do not answer this with one, none, or a ridiculous response please... this is serious
Answer:
https://geometryhelp.net/triangle-inequality-theorem/
Step-by-step explanation:
This is from that site. Visit it and you may find what you're looking for.
If we want to go from point A to point B, getting there through any intermediate point C, which is not on the straight line between A and B, is going to be longer. This should seem intuitively correct. But we will prove it formally.
Where do triangles come into this? Imagine that the line AB is a side of a triangle, ΔABC. Going from A to B is the straight, short way. Going there by first going to another point, C (which is the side AC) and then from C to B (which is the side CB) is going to be longer.

What values of the variable cannot possibly be solutions for the given equation, without actually solving the equation?
[tex] \frac{6}{3x + 2} - \frac{1}{x - 4} = 0[/tex]
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
Answer:
the solution to the equation is 8. Any value apart from 8 is not a solution
Step-by-step explanation:
Given the equation
6/3x+2 - 1/x-4 = 0
6/3x+2 = 1/x-4
Cross multiply
6(x-4) = 3x+2
6x - 24 = 3x+2
6x-3x = 2 + 24
3x = 24
x = 24/3
x = 8
Hence the solution to the equation is 8. Any value apart from 8 is not a solution

Use examples to show that Dexter is wrong.
Answer:
See Explanation
Step-by-step explanation:
Required
Prove that Dexter is wrong
To prove that Dexter is wrong, we use the following numbers.
[tex]Number = 4[/tex]
The factors are:
[tex]Factor = 1,2\ and\ 4[/tex]
3 factors
Using a greater number:
[tex]Number = 5[/tex]
The factors are:
[tex]Factor = 1\ and\ 5[/tex]
2 factors
From the above analysis:
4 has 3 factors and 5 has 2 factors; which shows that 5 has fewer factors
This shows that Dexter is wrong
One last stop before you head home. You and your friends are worn out, but you can’t help but stop for a candy apple to eat on the ride home from Snack Centra. Yum! You would like to take some home to your family, so what’s the best deal? You can purchase 5 apples for $6.25 or 8 apples for $9.25. What’s the best way to spend your last few bucks?
Answer:
8 apples for 9.25
Step-by-step explanation:
because 6.25 divided by 5 is 1.25, making each apple $1.25. and 9.25 divided by 8 is rounded to 1.16, making each apple cost $1.16.

6. When a company receives an order, there is a probability of 0.42 that its value is over $1000. If an order is valued at over $1000, then there is a probability of 0.63 that the customer will pay with a credit card. a. What is the probability that the next three independent orders will each be valued at over $1000
Answer:
0.074088
Step-by-step explanation:
Let
A:Value of order over $1000
B:Customer pay with credit card
We are given that
Probability of value of order over $1000,P(A)=0.42
If an order is valued at over $1000, then the probability that the customer will pay with a credit card, P(B/A)=0.63
We have to find the probability that the next three independent orders will each be valued at over $1000
We know that
When two two events A and B are independent then
[tex]P(A\cap B)=P(A)\cdot P(B)[/tex]
Using the formula
The probability that the next three independent orders will each be valued at over $1000=[tex]0.42\times 0.42\times 0.42[/tex]
The probability that the next three independent orders will each be valued at over $1000=0.074088
Kayla is thinking of a 3-digit number. * It is divisible by 18. * It is a palindrome (It reads the same left-to-right as it does right-to-left, like 252 and 848). * It is one less than a multiple of 5. What is Kayla’s number?
Answer:
414Step-by-step explanation:
Let the number be aba as it is a palindrome
It divisible by 18, so it is an even number with sum of digits divisible to 9
2a + b = 9kIt is one less than a multiple of 5:
aba = 100a + 10b + a = 101a + 10bMultiple of 5 will end with 0 or 5, it has to be 5 as a is even, then:
a = 5 - 1 = 4The number 4b4 is divisible by 9 only if b = 1:
2*4 + b = 9k ⇒ b = 1So the number is:
