Mr. Young has a section of his parking lot, measuring 10 yards by 12 yards, that needs to be repaved. The paving company told Mr. Young the workers complete square yards every hour. How long should it take to pave the parking lot?

Answers

Answer 1

To discover the area of the parking lot , you just need to multiply the length by the width ( 10 × 12 )
10 yards × 12 yards = 120 yards^2
if the take 1 hour to complete 1 square yard , the would take 120 hours to complete the intire parking lot.

Answers

To calculate the selling price of the item, you must apply the following formula:

Selling price=(Markup/Product costx100%)+Product cost

You have that:

Markup=40%
Product cost=$8.00

Given these values, you only have to substitute them into the formula of Selling price:

Find an equation for the plane that contains the line v = (−1, 1, 2) + t(7, 6, 2) and is perpendicular to the plane 8x + 5y − 7z + 8 = 0.

Answers

Final answer:

The equation for the plane that contains the given line and is perpendicular to the provided plane is 8x + 5y - 7z + 17 = 0.

Explanation:

To find an equation for the plane that contains the line given by v = (−1, 1, 2) + t(7, 6, 2) and is perpendicular to the plane described by 8x + 5y − 7z + 8 = 0, we first need to understand that the normal vector of this plane will be parallel to the normal vector (8, 5, -7) of the given plane since both planes are perpendicular to each other.

Knowing that the line lies on the required plane, we can use the point (−1, 1, 2) that the line passes through, along with the parallel normal vector, to write the equation of our plane. The general form of the equation of a plane is Ax + By + Cz + D = 0, where (A, B, C) is the normal vector to the plane. Substituting our point into the equation, we calculate the constant D.

Thus, the equation of our plane will be 8x + 5y − 7z + D = 0. Inserting the point (−1, 1, 2) into this equation gives us 8(-1) + 5(1) - 7(2) + D = 0, which simplifies to -8 + 5 - 14 + D = 0. Solving for D yields D = 17. Hence, the final equation of the plane is 8x + 5y − 7z + 17 = 0.

Using Cramer’s Rule, what is the value of x in the system of linear equations below? x+3y=16 3x+y=8

Answers

Final answer:

Using Cramer's Rule, the value of x in the given system of linear equations is 1.

Explanation:

We can solve the given system of equations using Cramer's Rule. Cramer's Rule states that in a system of linear equations, if the determinant of the coefficient matrix is non-zero, then the system has a unique solution.

First, let's find the determinant of the coefficient matrix:

| 1 3 |

| 3 1 |

Det = (1*1) - (3*3) = -8

Since the determinant is non-zero (-8 ≠ 0), the system has a unique solution.

Next, let's find the determinant of the x-column matrix:

| 16 3 |

| 8 1 |

Det(x) = (16*1) - (3*8) = -8

Finally, we can find the value of x by dividing the determinant of the x-column matrix by the determinant of the coefficient matrix: x = Det(x) / Det = (-8) / (-8) = 1.

Shirley is drawing triangles that have the same area. The base of each triangle varies inversely with the height. What are the possible base and height of a second triangle if the first triangle's base is 10 and its height is 6?

Answers

1. First, you must find the constant of variation (k). The problem indicates that the base of each triangle varies inversely with the height. So, this can be represented as below:

B=k/H

B is the base of the triangle (B=10).
H is the height of the triangle (H=6).
k is the constant of variation.

2. When you clear "k", you obtain:

B=k/H
k=BxH
k=10x6
k=60

3. Now, you have:

B=60/H

4. You can give any value to "H" and you will obtain the base of the second triangle.

5. If H=12, then:

B=60/H
B=60/12
B=5

6. Therefore, the possible base and height of a second triangle is:

B=5
H=12

Suppose that 44% of all Americans approve of the job the president is doing. The most recent Gallup poll consisted of a random sample of 1400 American adults.
A) What is the mean of the sampling distribution?
B) What is the standard deviation of the sampling distribution?
C) Describe the normal approximation for this sampling distribution.
D) What is the probability that the Gallup poll will come up with a proportion within 3 percentage points of the true 44%?

Answers

This is a typical binomial distribution since we are dealing with only two possible outcomes. For this distribution we have:
n = population = 1400
p = probability of positive answer = 0.44

A) The mean of a binomial distribution is
μ = np
= 1400 × 0.44
= 616

Hence, μ = 616

B) The standard deviation of a binomial distribution is
σ = √[np(1 - p)]
   = √[1400×0.44×(1-0.44)]
   = √(1400×0.44×0.56)
   = 18.6

Hence, σ = 18.6

C) A binomial distribution B(n, p) can be approximated by a normal distribution N(μ, σ) only when:
np ≥ 10 (we have 616 > 10)
np(1 - p) ≥ 10 (we have 344.96 > 10)

Hence, the normal approximation is N(616, 18.6)

D) We need to calculate the probability of the sample population to be within 3% of the true mean.

In order to do so, as a first thing, we need to calculate the sample standard deviation, which will be given by the formula:
[tex]\sigma = \sqrt{ \frac{p(1-p)}{n} } [/tex]
= √[0.44 × (1 - 0.44) ÷ 1400]
= √0.000176
= 0.013

Now, we need to calculate the z-score associated with the values we want: since we want 3% from the mean, it means between 41% and 47%.
The z-score can be calculated by the formula:
z = (Y - p) / σ
z₁ = (0.41 - 0.44) / 0.013 = -2.31
z₂ = (0.47 - 0.44) / 0.013 = 2.31

Therefore, we can write
P(0.41 ≤ Y ≤ 0.47) = P(-2.31 ≤ z ≤ 2.31)
= P(z ≤ 2.31) - P(z ≤ -2.31)
= P(z ≤ 2.31) - [1 - P(z ≤ 2.31)]
= 2×P(z ≤ 2.31) - 1

From a standard normal distribution table, we find:
P(z ≤ 2.31) = 0.9896

Therefore:
2×P(z ≤ 2.31) - 1 = 2 × 0.9896 - 1
= 0.9792

Hence, the probability to find a proportion within 3% of the real mean is 97.92%

Given unit circle, so radius=1.

We calculate lengths of vertical segments, with the help of Pythagoras Theorem, based on a right triangle radiating from circle centre O, and hypotenuse from O to a point on the circumference.
AO=1 (given unit circle)
BB'=sqrt(1^2-0.25^2)=0.968246
CC'=sqrt(1^2-0.5^2)=0.866025
DD'=sqrt(1^2-0.75^2)=0.661438
EE'=0

Now we proceed to calculate the segments approximating the arc. Again, we use a right triangle in which the hypotenuse is the segment joining two points on the circumference. The height is the difference between the two vertical segments, and the base is 0.25 for all four segments.
AB=sqrt((AO-BB)^2+0.25^2)=0.252009BC=sqrt((BB-CC)^2+0.25^2)=0.270091CD=sqrt((CC-DD)^2+0.25^2)=0.323042DE=sqrt((DD-0)^2+0.25^2)=0.7071068

Regina scored 84% on a test. She answered 63 items correctly. How many items did Regina answer incorrectly?

Answers

84% is equivalent to 63 correct questions.

Divide both sides by 84% to normalize:

84%/84% = 63/84%
1 = 75

This means that 100% would be equivalent to 75 questions correct

From here, subtract 75-63=12

STEP 1:
Find total number of questions on the test. The percent (84%) is out of 100%. So set up a proportion. 84% out of 100% is 63 out of x (total number of questions on the test).

x= total # questions on test

63/x= 84%/100%
cross multiply
(63*100)= (x*84)
6300= 84x
divide both sides by 84
75= x (total # on test)

STEP 2:
Subtract number correct from total number of questions to equal number incorrect.

x= number incorrect on test

x= 75 - 63
x= 12 incorrect answers

ANSWER: 12 incorrect answers

Explain how to compare 43 and 35

Final answer:

The element with 35 protons is bromine (Br). Its isotopes with 44 and 46 neutrons have the symbols ^79Br and ^81Br, respectively, with the mass numbers derived from adding the number of neutrons to the atomic number 35.

Explanation:

To address Exercise 1.8.2, we first need to identify the element with 35 protons. In the periodic table, the element with 35 protons is bromine (Br). This element is defined by the number of protons in its nucleus, which is also known as its atomic number. Therefore, bromine is the element we are looking for.

Next, we need to write the symbols for bromine's isotopes with 44 and 46 neutrons. The total number of nucleons (protons plus neutrons) gives us the mass number of an isotope. For bromine with 44 neutrons, the mass number is 35 (protons) + 44 (neutrons) = 79. Therefore, the symbol for this isotope of bromine is ^79Br.

For the isotope with 46 neutrons, the mass number is 35 (protons) + 46 (neutrons) = 81. So, the symbol for this isotope of bromine is ^81Br. Each isotope differs in the number of neutrons, and therefore, in the mass number, while the number of protons (the atomic number) remains constant.

Final answer:

The element with 35 protons is bromine (Br). Its isotopes with 44 and 46 neutrons are written as ^79Br and ^81Br, respectively, where the numbers represent the mass numbers of each isotope.

Explanation:

To answer Exercise 1.8.2, we must first identify the element with 35 protons. The element with 35 protons is bromine, which is represented by the chemical symbol Br. To write the symbols for its isotopes with 44 and 46 neutrons, we must add the atomic number (protons) and the number of neutrons to get the mass number for each isotope.

For the isotope with 44 neutrons:

Mass number = Number of protons + Number of neutronsMass number = 35 + 44Mass number = 79Therefore, the symbol for this isotope is ^79Br.

For the isotope with 46 neutrons:

Mass number = 35 + 46Mass number = 81Therefore, the symbol for this isotope is ^81Br.

Isotopes of an element have the same number of protons but different numbers of neutrons, hence different mass numbers. The isotopes of bromine are thus ^79Br and ^81Br, referring to the atomic mass which is composed of the protons and neutrons together.
