Mortgage lenders base the mortgage interest rate they offer you on your credit rating. This makes it financially critical to maintain a credit score of 740 or higher. How much more interest would you pay on a $195,000 home if you put 20% down and financed the balance with a 30-year mortgage at 6% compared to a 30-year mortgage at 3 1/2%?

Answer:

The greatest number is A. 1.3 * 10⁵

Step-by-step explanation:

Let's find the greatest number:

Option A : 1.3 * 10⁵ = 1.3 * 100,000 = 130,000

Option B : 9.8 * 10² = 9.8 * 100 = 980

Option C : 9.6 * 10⁴ = 9.6 * 10,000 = 96,000

Option D : 4.6 * 10⁻⁵ = 4.6 * 0.00001 = 0.000046

130,000 > 96,000 > 980 > 0.000046

The greatest number is A. 1.3 * 10⁵

The theater sold 82 children tickets and 60 adult tickets.

Step-by-step explanation:

No. of tickets sold = 142

Total sales = $890

Cost of one child ticket = $5

Cost of one adult ticket = $8

Let,

x be the number of children tickets

y be the number of adult tickets

According to given statement;

x+y=142    Eqn 1

5x+8y=890   Eqn 2

Multiplying Eqn 1 by 5

[tex]5(x+y=142)\\5x+5y=710\ \ \ Eqn\ 3[/tex]

Subtracting Eqn 3 from Eqn 2

[tex](5x+8y)-(5x+5y)=890-710\\5x+8y-5x-5y=180\\3y=180[/tex]

Dividing both sides by 3

[tex]\frac{3y}{3}=\frac{180}{3}\\y=60[/tex]

Putting =60 in Eqn 1

[tex]x+60=142\\x=142-60\\x=82[/tex]

The theater sold 82 children tickets and 60 adult tickets.

Apolline charges a fixed initial fee and a constant fee for each hour for mowing work.

If we try to model the above conditions with a total cost for mowing as C for working for h hours then we will get  

C = a + bh ....... (1)

Where a is the initial fee and b is the rate of charge per hour of work.

Now, her fee for a 5-hour job is $42 and her fee for a 3-hour job is $28.

Hence, from equation (1),  

42 = a + 5b ........ (2) and

28 = a + 3b ......... (3)  

Now, solving equations (2) and (3) we get 2b = 42 - 28 = 14

⇒ b = 7 dollars per hour of work.

And from equation (3) we get, a = 28 - 3b = 7 dollars.

So, the equation (1) becomes C = 7 + 7h ....... (4)

Answer:

7 meters

Step-by-step explanation:

Assume that the length is l and the width is w. Therefore, l is equal to 7 times its width (7*w) minus 28, or l=7*w-28. As we know that w*l = area = 9555, we can plug our value for l in to limit our equation to 1 variable, resulting in w*(7*w-28) = 9555. Adding 28 to both sides to separate the 7w (because we want to solve for that), we get 9583=7w. Then, to solve for the width, we can divide both sides by 7 to get that 9583/7=1369=w. Plugging that back into the formula that w*l=area, we get that 1369*l=9583 -- dividing 1369 from both sides to separate l, we get that l=7.

To find the length of a rectangle where the area is 9555 square meters and the length is 28 meters less than 7 times its width, express the length in terms of the width, use the area to form a quadratic equation, solve for the width, and substitute it back to find the length.

To find the length of the rectangle when the area is 9555 square meters and the length is 28 meters less than 7 times its width, let's denote the width of the rectangle as w and the length as l. According to the problem, the length l can be expressed as l = 7w - 28. The area of a rectangle is the product of its length and width, which gives us the equation w × (7w - 28) = 9555.

To find the value of w, we need to solve the quadratic equation 7w2 - 28w - 9555 = 0. Factoring or using the quadratic formula leads to the width, and substituting this back into l = 7w - 28 gives us the length of the rectangle. In solving, ensure to discard the negative value of w as a width cannot be negative.

Once we calculate the width w, the length is found by multiplying it by 7 and then subtracting 28. This process will provide the final length of the rectangle.

Using probability and binomial distribution, we determined that the probability of exactly 5 out of 40 machines not working is approximately 0.18. The probability that all machines are working is around 0.024, and the probability that at least one machine is working is almost certain, approximately 1.

To address this problem, we will use the concepts of probability and the binomial distribution.

Calculating the Probabilities:

Let’s denote the probability of a single machine not working as p = 0.12. The probability of a single machine working is q = 1 - p = 0.88.

1. Probability that exactly 5 out of 40 machines are not working

We can use the binomial distribution formula:

P(X = 5) = C(40, 5) * p^5 * q^(40-5)

Where C(40, 5) is the number of combinations of 40 machines taken 5 at a time.

C(40, 5) = 40! / [5!(40-5)!] = 658,008

Therefore:

P(X = 5) = 658,008 * (0.12)^5 * (0.88)^35 ≈ 0.18 (using a calculator for binomial probability)

2. Probability that all 40 machines are working

This can be found by raising the probability of one machine working to the power of 40:

P(all working) = q^40 = 0.88^40 ≈ 0.024

3. Probability that at least one machine is working

The easiest way to calculate this is to find the complement of the probability that none are working and subtract it from 1:

P(none working) = p^40 = (0.12)^40 ≈ 9.0949 x 10^-38 (which is extremely close to 0)

P(at least one working) = 1 - P(none working) ≈ 1 - 0 = 1

Final answer: A company has 200 machines. Each machine has 12% probability of not working. If you were to pick 40 machines randomly, the probability that 5 would not be working is _0.18_ , the probability that all would be working is_0.024_, and the probability that at least one machine would be working is_1_.

Complete question:

A company has 200 machines. Each machine has 12% probability of not working. If you were to pick 40 machines randomly, the probability that 5 would not be working is ____ , the probability that all would be working is____, and the probability that at least one machine would be working is______

If you were to pick 40 machines randomly, the probability that 5 would not be working is 0.186 , the probability that all would be working is 0.011, and the probability that at least one machine would be working is 0.989.

This problem involves probability calculations for a company that has 200 machines, each with a 12% chance of not working. Let's break down the calculations step-by-step:

1. Probability that 5 out of 40 machines are not working:

This can be modeled using the binomial distribution. The binomial formula is:

[tex]P(X = k) = C(n, k) \times p^k \times (1-p)^{(n-k)[/tex]

where:

For our problem, it becomes:

P(X = 5) = C(40, 5) × (0.12)⁵ × (0.88)³⁵

= 0.186

2. Probability that all 40 machines are working:

This is calculated using the complement probability as follows:

P(All working) = (0.88)⁴⁰

≈ 0.011

3. Probability that at least one machine is working:

This can be calculated using the complement rule:

P(At least one working) = 1 - P(None working)

= 1 - (0.88)⁴⁰

≈ 0.989

Answer:

Step-by-step explanation:

the unit rate of rainfall is [tex]\( \frac{1}{8} \)[/tex] inches per hour.

To find the unit rate of rainfall, which is the amount of rain per unit of time, we divide the total amount of rain by the total time.

Given:

Total amount of rain: 9 inches

Total time: 72 hours

Step 1: Divide the total amount of rain by the total time:

[tex]\[ \text{Unit rate} = \frac{\text{Total amount of rain}}{\text{Total time}} \][/tex]

[tex]\[ \text{Unit rate} = \frac{9 \text{ inches}}{72 \text{ hours}} \][/tex]

Step 2: Simplify the expression:

To simplify the unit rate, we divide 9 by 72.

[tex]\[ \text{Unit rate} = \frac{9}{72} \text{ inches per hour} \][/tex]

Step 3: Simplify the fraction:

[tex]\[ \text{Unit rate} = \frac{1}{8} \text{ inches per hour} \][/tex]

So, the unit rate of rainfall is [tex]\( \frac{1}{8} \)[/tex] inches per hour.

we know that

The algebraic expression that represent this problem is

[tex]x^{2} =15x+286[/tex]

so

[tex]x^{2}-15x-286=0[/tex]

The formula to solve a quadratic equation of the form

[tex]ax^{2} +bx+c=0[/tex]

is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]x^{2}-15x-286=0[/tex]

so

[tex]a=1\\b=-15\\c=-286[/tex]

substitute in the formula

[tex]x=\frac{-(-15)(+/-)\sqrt{-15^{2}-4(1)(-286)}} {2(1)}[/tex]

[tex]x=\frac{15(+/-)\sqrt{1,369}} {2}[/tex]

[tex]x=\frac{15(+/-)37}{2}[/tex]

[tex]x_1=\frac{15(+)37}{2}=26[/tex]

Final answer:

The polynomial x² + x - 6 factors to (x + 3)(x - 2) by finding two numbers that multiply to -6 and add to 1.

Explanation:

To factor the polynomial x² + x - 6, one needs to find two numbers that multiply to -6 (the constant term) and add up to 1 (the coefficient of the middle term, x). These numbers are 3 and -2, because 3 × (-2) = -6, and 3 + (-2) = 1. Therefore, the factored form of the polynomial is (x + 3)(x - 2).

y = (2ab+2bc-6bc)/(3(a-2c))

y = (2ab-4bc)/(3(a-2c))

y = (2b*a-2b*2c)/(3(a-2c))

y = 2b(a-2c)/(3(a-2c))

Using the properties of operations the given pair of expressions are not equivalent

Solution:

Given that, we have to use the properties of operations to determine if each pair of expressions is equivalent

And the two expressions are:

Now, we know that, there are four (4) basic properties of operations:

Commutative, Associative, Distributive and Identity. These properties only apply to the operations of addition and multiplication.

So, if we observe we can apply distributive property on 1st expression

The distributive property of multiplication states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum.

[tex]\begin{array}{l}{\frac{1}{2}(4-2 x) \rightarrow \frac{1}{2}(4)-\frac{1}{2}(2 x)} \\\\ {\rightarrow 2-x}\end{array}[/tex]

This answer clarifies the true statement about the division of 1.23 by 0.15, highlighting key misconceptions about the dividend, divisor, and quotient.

Explanation:

Which statement about 1.23 ÷ 0.15 is true?

The dividend should become 15. This statement is false as the dividend after the division remains 1.23.

The divisor is a whole number. This statement is false as 0.15 is not a whole number.

The quotient does not have a hundredths place. This statement is true as the quotient after dividing 1.23 by 0.15 is 8.2, which does not have a hundredths place.

Answer:

48.92

Step-by-step explanation:

A= (1/2)(b)(h)

A=(1/2)(1.56)(3.92)=3.0576

A=(3.0567)(16)=48.9216

A=48.92

The approximate area of Circle A can be found by understanding that the base of a sector is part of the circumference, and using the radius (height) value of 3.92 units in the area formula A = πr². Accounting for significant figures, the area of Circle A is approximately 48 units².

To find the approximate area of Circle A, we need to understand that the base of a sector, which is a part of the circumference of the circle, is close to the length of the arc for a small sector. By dissecting the circle into 16 congruent sectors, each sector represents 1/16 of the circle's full circumference. Since the base of one sector is given as 1.56 units, if we multiply this by 16, we would have the total circumference of the circle. However, the value provided for the 'height' is indeed the radius of the whole circle, which is 3.92 units. The area of a circle is calculated using the formula A = πr².

Using the radius (3.92 units), we can calculate the area:

A = π * (3.92 units)²

A = 3.1415927 * 15.3664 units²

A = 48.2544695988 units²

Considering the significant figures provided in the question, we should limit the calculated area of the circle to two significant figures, matching the least number of significant figures we were originally given, which were in the radius measurement. Therefore, the approximate area of Circle A is:

A = 48 units²

t = 3.3 seconds

Step-by-step explanation:

From the formula of vertical motion of an object under gravity we can write the equation

[tex]H = ut + \frac{1}{2} gt^{2}[/tex] ....... (1)

Where u is the initial velocity (in feet per second) of throw of the object and t is time of travel in seconds and the value of g i.e. gravitational acceleration is 32 feet/sec².

Now, while a ball is thrown vertically upward with velocity 50 ft/sec from a height of 7 ft then the time of travel of the ball before reaching the ground, the equation (1) will be written as

[tex]- 7 = 50t - \frac{1}{2} \times 32 \times t^{2}[/tex]

As we have selected the upward direction as positive so, gravitational acceleration,g will be negative and as the displacement is downward by 7 feet, so it will be negative.

⇒ 16t² - 50t - 7 = 0 ........ (2)

Now, applying Sridhar Acharya formula,

[tex]t = \frac{-(-50) + \sqrt{(-50)^{2} - 4(16)(-7)}}{2(16)}[/tex] {Neglecting the negative root as t can not be negative}
