Answer:

[tex]x -3e^{-x} + C[/tex]

Step-by-step explanation:

Given the integral [tex]\int\limits {\dfrac{e^{x}+3}{e^x} } \, dx[/tex], we are to evaluate it. Note that sum of integral is equal to the integral of its individual sum as  shown;

[tex]\int\limits {\dfrac{e^{x}+3}{e^x} } \, dx = \int\limits {\dfrac{e^{x}}{e^x} } \, dx + \int\limits {\dfrac{3}{e^x} } \, dx[/tex]

[tex]= \int\limits 1\, dx + 3\int\limits {e^{-x} \, dx \\\\[/tex]

[tex]= x + 3(-e^{-x})\\\\= x -3e^{-x} + C[/tex]

Hence the value of the evaluated integral is [tex]x -3e^{-x} + C[/tex] where C is the constant of integration.

Answer:

$1900

Step-by-step explanation:

Starting from the equation of simple interest, which is defined as follows:

I = P * r * t

Being I the interest, P the value of the product, r the interest rate and t would be time.

We want to know the price of the product, therefore, solving the equation we have:

P = I / r * t

We know each other's values so we replace:

P = 1026 / (0.135 * 4)

P = $ 1900 was the value of the refrigerator Jaime bought

Answer and Step-by-step explanation:

This regression can generate an omitted variable bias, because the researcher did not determine any parameters or real data to measure it. In this case, the researcher determined the crime rate as a dependent variable, but did not establish the facts that influence it and that promote an observable result. In this way, he omitted the independent variable and his research will be inaccurate and incorrect. To control this bias, it is necessary for the researcher to provide a dependent variable such as the level of education in the region, the income distribution in the region, the unemployment rate, the fraction of young men, among others.

Answer:

Sammy has the greatest amount.

Step-by-step explanation:

I figured that out because half of 1,000,000 is 500,000 , and Laila had 1,000,000 but gave Sammy half of that money , and Sammy had already started out with 90,000 , So 500,000 + 90,000 = 590,000 . So that means Laila is stuck with the 500,000 while Sammy has the 90,000 she started off with and the 500,000 Laila gave her .

Answer:

Measure of third side = 2.1 inches

Step-by-step explanation:

Perimeter of any polygon = Sum of lengths of all sides of the polygon

From the figure attached,

Number of sides of the polygon = 3

Therefore, perimeter of a triangle = sum of all three sides of the given triangle

Length of two sides = 1.7 inches and 3.4 inches.

Let the third side = x inches

Perimeter of the triangle = 7.2 inches

By the definition of the perimeter,

7.2 = 1.7 + 3.4 + x

7.2 = 5.1 + x

x = 7.2 - 5.1

x = 2.1 inches

Therefore, third side of the given triangle is 2.1 in.

Answer:

c. The square root of 12 is between 4 & 5.

Step-by-step explanation:

a. The square root of 112 is between 10 & 11

i. Find the squares of 10 & 11

10² = 100

11² = 121

Because 100 < 112 < 121, we know the square root of 112 is between 10 & 11

b. The square root of 180 is between 13 & 14

i. Find the squares of 13 & 14

13² = 169

14² = 196

Because 169 < 180 < 196, we know that the square root of 180 is between 13 & 14

c. The square root of 12 is between 4 & 5.

i. Find the squares of 4 & 5

4² = 16

5² = 25

Because 12 < 16 & 25, we know that the square root of 12 is not between 4 & 5.

d. The square root of 5 is between 2 & 3.

i. Find the squares of 2 & 3

2² = 4

3² = 9

Because 4 < 5 < 9, we know that the square root of 5 is between 2 & 3.

Answer:

Let x represent: the price per lime.

Let y represent: the price per avocado.

System: 6*x + 2*y = $7.50

               2*x + y =$3.00

Solution: x = $0.75     y = $1.50

Step-by-step explanation:

Here we have two variables, x and y.

Let's take x =  price per lime, and y = price per avocado.

We know that when he bought 6 limes and 2 avocados he paid $7.50, so we can write this as:

6*x + 2*y = $7.50

And we also know that when he bought 2 limes and 1 avocado, he paid $3.00

2*x + 1*y = $3.00

Then we have a system of equations:

6*x + 2*y = $7.50

2*x + y =$3.00

Now we want to solve this system,

The first step is isolating one of the variables in one of the equations, let's isolate y in the second equation:

y = $3.00 - 2*x

Now we can replace this into the other equation:

6*x + 2*($3.00 - 2*x) = $7.50

6*x + $6.00 - 4*x = $7.50

$6.00 +  2*x = $7.50

2*x = $7.50 - $6.00 = $1.50

x = $1.50/2 = $0.75

now we can find the value of y.

y  = $3.00 - 2*x = $3.00 - 2*$0.75 = $1.50

Answer:

Z = -1.333

P-value  = 0.09176

Decision Rule: Reject [tex]H_o[/tex] if ∝  is greater than the P-value

Conclusion: Since P-value is >  the level of significance ∝, we fail to reject the null hypothesis, therefore there is insufficient evidence to conclude that at least half of all voters prefer the Democrat.

Step-by-step explanation:

Given that:

The sample size of the poll = 1068

The proportion of voters that preferred Democratic candidate is [tex]\hat p[/tex] = 0.48

To test the claim that at least half of all voters prefer the Democrat, i.e 1/2 = 0.5

The null hypothesis and the alternative hypothesis can be computed as:

[tex]H_o : p \geq 0.50[/tex]

[tex]H_1 : p < 0.50[/tex]

Using the Z test statistics which can be expressed by the formula:

[tex]Z = \dfrac{\hat p - p}{\dfrac{\sqrt{p(1-p) }}{n}}}[/tex]

[tex]Z = \dfrac{0.48 - 0.5}{\dfrac{\sqrt{0.5(1-0.5) }}{1068}}}[/tex]

[tex]Z = \dfrac{-0.02}{\sqrt{\dfrac{{0.5(0.5) }}{1068}}}[/tex]

[tex]Z = \dfrac{-0.02}{\sqrt{\dfrac{{0.25}}{1068}}}[/tex]

[tex]Z = \dfrac{-0.02}{0.015}[/tex]

Z = -1.333

P-value = P(Z< -1.33)

From z tables,

P-value  = 0.09176

The level of significance ∝ = 0.05

Decision Rule: Reject [tex]H_o[/tex] if ∝  is greater than the P-value

Conclusion: Since P-value is >  the level of significance ∝, we fail to reject the null hypothesis, therefore there is insufficient evidence to conclude that at least half of all voters prefer the Democrat.

Answer:

A. $147.67

B. $26,581.49

C.  Principal: 65.8352%

C.  Interest: 34.1647%

The values:

a) PMT = $147.67.

b) $26580.6

c) Of the total amount paid, 65.84 percentage is paid toward the principal and 34.16 percentage is paid for the interest.

The formula:

PV = PMT/i[1 - {1/(1+i)ⁿ]

PV denotes the loan sum.

PMT stands for "monthly payment," I for "interest rate" (interest rate % divided by 12), and "n" for the number of months (term of the loan in months)

Given:

Consider a student loan of $17,500 at a fixed APR of 6% for 15 years.

PV is the loan amount = 17500

PMT is the monthly payment .

i is the interest rate per month in decimal form (interest rate percentage divided by 12)

i = 0.06/12 = 0.005

n is the number of months (term of the loan in months)

n = 180 months.

The monthly payment,

PMT = PV i(1+i)ⁿ/{(1+i)ⁿ-1}

PMT = 17500(0.005)(1.005)⁴⁸/{(1.005)⁴⁸-1}

PMT = $147.67.

The total amount paid over the term of the loan,

= 147.67 x 180 = $26580.6

Of the total amount paid, 65.84 percentage is paid toward the principal and 34.16 percentage is paid for the interest.

Therefore, all the required values are given above.

Answer:

Step-by-step explanation:

1.) Divide 78 by 4

2.) Multiply 19.5 by 3

OR

1.) Change 78 to 78/1

2.) Multiply 78/1 by 3/4

3.) Smile because you got the answer right :)

Her heart beats 58.5 beats in 3/4 of a minute.

We have Patricia's normal heart rate.

We have to determine how many times does her heart beat in 3/4 of a minute.

A normal resting heart rate for adults ranges from 60 to 100 beats per minute.

According to the question -

Patricia's normal heart rate = 78 beats per minute.

Now - 3/4 of a minute = 3/4  x  60 =  15 x 3 = 45 seconds.

Now -

60 seconds → 78 beats

1 second → (78/60) beats

45 seconds → (78/60) x 45 = 58.5 beats

Hence, her heart beats 58.5 beats in 3/4 of a minute.
