If the number when rounded to 2 decimal places is equal to 9.68, then the upper bound is 9.685 and lower bound is 9.675 .
In order to find the upper bound of the number y, we need to add 0.005,
and to find the lower bound of the number y, we need to subtract 0.005 ,
We know that, the number y, when rounded to 2 decimal places is equal to 9.68 ;
So, the Upper Bound is = 9.68 + 0.005 = 9.685, and
The Lower Bound is = 9.68 - 0.005 = 9.675.
Therefore, the lower bound of y is 9.675 and upper bound of y is 9.685.

(a) To show that {v1,…,vk,w1,…,wℓ} is an orthogonal set, we must show that the inner product of any two distinct vectors in this set is 0.
(b) To show that {v1,…,vk,w1,…,wℓ} is a basis of Rn, we must show that any vector in Rn can be written as a linear combination of these vectors.
(c) To show that dim V + dim V⊥ = n, we must show that the number of vectors in {v1,…,vk,w1,…,wℓ} is equal to n.
Let v and w be any two distinct vectors in the set {v1,…,vk,w1,…,wℓ}. By definition, since {v1,…,vk} is an orthogonal basis of a subspace V of Rn and {w1,…,wℓ} is an orthogonal basis of V⊥, we have that v and w are either in V or in V⊥, but not both.
Thus, if v is in V, then we have = 0, because w is in V⊥. Similarly, if w is in V⊥, then = 0, because v is in V. Therefore, = 0 for any two distinct vectors v and w in {v1,…,vk,w1,…,wℓ}, which implies that {v1,…,vk,w1,…,wℓ} is an orthogonal set.
(b) Let x be any vector in Rn. Since {v1,…,vk} is a basis of V, x can be written as a linear combination of the vectors in {v1,…,vk}, that is, x = a1v1 + a2v2 + ... + akvk.
Since {w1,…,wℓ} is a basis of V⊥, x can also be written as a linear combination of the vectors in {w1,…,wℓ}, that is, x = b1w1 + b2w2 + ... + bℓwℓ.
Combining these two equations, we can write x = (a1v1 + a2v2 + ... + akvk) + (b1w1 + b2w2 + ... + bℓwℓ). Thus, any vector in Rn can be written as a linear combination of the vectors in {v1,…,vk,w1,…,wℓ}, which implies that {v1,…,vk,w1,…,wℓ} is a basis of Rn.
By definition, {v1,…,vk} is an orthogonal basis of a subspace V of Rn, so dim V = k. Similarly, {w1,…,wℓ} is an orthogonal basis of V⊥, so dim V⊥ = ℓ. Thus, the number of vectors in {v1,…,vk,w1,…,wℓ} is k + ℓ = n, which implies that dim V + dim V⊥ = n.

Step-by-step explanation: try to solve for a by itself by multiplying it on both sides that give you 3 = 1*a. that simply just means that a is equal to 3, so you substitute three to the a variable that will give 3/3 that's equal to 1.
(1 point) If the 100th term of an arithmetic sequence is 783, and its common difference is 8, then its first term a = 9 its second term Q2 = its third term az = (1 point) Express the following sum i
The first term is 9, the second term is 17, and the third term is 25.
The 100th term of an arithmetic sequence is given by the formula:
Tn = a + (n-1)d
Where Tn is the nth term, a is the first term, n is the number of terms, and d is the common difference.
In this case, the 100th term is 783, the common difference is 8, and the first term is 9.
Plugging in the values into the formula, we get:
783 = 9 + (100-1)8
Solving for the first term, we get:
783 = 9 + 792
783 = 801
a = 9
The second term, Q2, can be found by adding the common difference to the first term:
Q2 = a + d
Q2 = 9 + 8
Q2 = 17
The third term, az, can be found by adding the common difference to the second term:
az = Q2 + d
az = 17 + 8
az = 25
the first term is 9, the second term is 17, and the third term is 25.

What is a linear equation?
A linear equation is one in which the maximum power of the variable is one. Mathematically, an equation of the type axe + b = 0 or axe + by + c = 0, where a, b, and c are real integers and x and y are variables of maximum power one.
We know that,
Students under age 15 who prefer walk/bike + Students age 15 and above who prefer walk/bike = total of column
So, Students under age 15 who prefer walk/bike
= total of column - Students age 15 and above who prefer walk/bike
= 152 - 65
= 87.
Now, total of rows = total of columns
Row 1 + Row 2 = 360
Row 1 = 360 - Row 2
=360-195
= 165.
Now, Students under age 15 who prefer bus + Students under age 15 who prefer walk/bike + Students under age 15 who prefer car = Row table
So, Students under age 15 who prefer bus
= 165 - 60 - 87
= 18.
Similarly,
Students under age 15 who prefer bus + Students 15 and above who prefer bus = column total
So, Students 15 and above who prefer bus = 110 - 18
= 92.
Finally, students age 15 and above take a car to school
= 195 - 92 - 65
= 38.

If each hamburger she makes has a mass of about 0. 125 kg she can make a maximum of 16 hamburgers with the amount of ground beef she has.
To determine how many hamburgers Kendra can make, we need to divide the total mass of ground beef by the mass of each hamburger:
Total mass of ground beef = 0.652 kg + 0.545 kg + 0.824 kg = 2.021 kg
Number of hamburgers = Total mass of ground beef / Mass of each hamburger
Number of hamburgers = 2.021 kg / 0.125 kg = 16.168
Since Kendra can only make whole hamburgers, she can make a maximum of 16 hamburgers with the amount of ground beef she has.

One leg of a right triangle measures 7 feet. If the other leg is 1 foot shorter than the hypotenuse, find the dimensions of the triangle.
One leg of a right triangle measures 7 feet. If the other leg is 1 foot shorter than the hypotenuse, the dimensions of the right triangle will be 7 feet, 24 feet, and 25 feet.
To find the dimensions of the right triangle, we can use the Pythagorean Theorem, which states that for any right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two legs. The formula for the Pythagorean Theorem is a² + b2 = c2, where a and b are the lengths of the legs and c is the length of the hypotenuse.
We are given that one leg of the triangle measures 7 feet, and the other leg is 1 foot shorter than the hypotenuse. Let's call the length of the other leg x and the length of the hypotenuse x + 1. We can plug these values into the Pythagorean Theorem to find the dimensions of the triangle:
72 + x2 = (x + 1)2
49 + x2 = x2 + 2x + 1
48 = 2x
x = 24
So the other leg of the triangle measures 24 feet, and the hypotenuse measures 24 + 1 = 25 feet. The dimensions of the right triangle are 7 feet, 24 feet, and 25 feet.

Bob's gift shop sold a record number of cards for Mother's Day. One salesman sold 47 cards, which was 4% of the cards sold for Mother's Day. How many cards were sold for Mother's Day?
Answer:
We can use the concept of percentage to solve this problem.
Let's represent the total number of cards sold for Mother's Day by "x". We know that one salesman sold 47 cards, which was 4% of the total number of cards sold. So we can set up an equation:
0.04x = 47
Solving for "x", we divide both sides by 0.04:
x = 47 / 0.04
Using a calculator, we get:
x = 1175
Therefore, the total number of cards sold for Mother's Day was 1175.

The exponential functions y=1.2ˣ shows exponential growth and y=0.71ˣ shows exponential decay.
What exactly are exponential functions?
Exponential functions are functions that involve a variable exponent. They are of the form f(x) = aˣ, where "a" is a positive constant base and "x" is the variable exponent.
Exponential functions exhibit rapid growth or decay, depending on the value of "a" and the sign of "x". For example, if "a" is greater than 1, the function grows rapidly as "x" increases, while if "a" is between 0 and 1, the function decays rapidly as "x" increases.
Now,
As stated above that for exponential function y=aˣ
when a>1 it shows exponential growth
and when a<1 it shows decay.
hence,
The exponential functions y=1.2ˣ shows exponential growth and y=0.71ˣ shows exponential decay.

The amount of overtime that Diego would earn would be D. $ 148. 50.
How to find the overtime ?Diego's regular rate is $11 per hour. When he works overtime, he is paid time-and-a-half of his regular rate, which means he earns an additional 50% of his regular rate for each hour of overtime.
So his overtime rate is:
= 11 + ( 11 x 0.5)
= 11 + 5.50
= $16.50 per hour
If Diego works 9 hours of overtime in a week, he would earn:
= 9 x 16.50
= $ 148. 50
In conclusion, if Diego was to work 9 hours of overtime, he would be paid $ 148. 50 for his efforts.

Subtract. (7)/(12vx^(2))-(3)/(8v^(2)x) Simplify your answer as much as possible.
Subtracting the expression (3)/(8v²x) from the expression (7)/(12vx²) will result to the expression (14v - 9x)/(24v²x²).
To subtract the two fractions, we need to find a common denominator. The least common denominator (LCD) is the least common multiple of the denominators of two or more fractions, and it is used to find a common denominator so that we can perform operations on them. The LCD of 12vx² and 8v²x is 24v²x². We can then multiply each fraction by the LCD to get the same denominator and subtract the numerators.
(7)/(12vx²) x (24v²x²)/(24v²x²) - (3)/(8v²x) x (24v²x²)/(24v²x²) = (14v)/(24v²x²) - (9x)/(24v²x²) = (14v - 9x)/(24v²x²)
So the simplified answer is (14v - 9x)/(24v²x²).

Answer:
hypothesis of the medicine is incomplete
Step-by-step explanation:
so we have.to apply bodmas
When the the doctor's claim is correct, the probability that exactly 19 patients will recover when given the new medicine is 0.1444.
How to calculate the probabilitya) The suitable distribution to model the number of patients in this sample who recover when given the new medicine is the binomial distribution. We can assume that each patient has a fixed probability of success (i.e., recovering) and that the outcomes of each patient are independent of each other.
b) If the claim is correct, then the probability of success (recovering) for each patient is p = 0.8. Let X be the number of patients in the sample who recover when given the new medicine. Then X follows a binomial distribution with parameters n = 25 (the sample size) and p = 0.8 (the probability of success).
The probability of exactly 19 patients recovering is given by:
P(X = 19) = (25 choose 19) * (0.8)^19 * (1-0.8)^(25-19)
where (25 choose 19) is the binomial coefficient, which represents the number of ways to choose 19 patients out of 25.
Using a calculator, we can compute:
P(X = 19) = 0.1444
Therefore, if the doctor's claim is correct, the probability that exactly 19 patients will recover when given the new medicine is 0.1444.
