Answer:

interest rate = 0.0400215403 or 4.00215403% or 4%

Step-by-step explanation:

formula

final amount =

initial amount times e^(interest rate times time)

6614 = 4998 times e^(interest rate times 7)

(6614 ÷ 4998) = e^(interest rate times 7)

1.32332933173 = e^(interest rate times 7)

ln means natual log

ln(1.32332933173) = ln(e^(interest rate times 7))

0.28015078214 = interest rate times 7

0.28015078214 ÷ 7 = interest rate

0.0400215403 = interest rate

The probability of rolling a number greater than 2 is 2/3

From the question, we have the following parameters that can be used in our computation:

Rolling a number cube once

Using the above as a guide, we have the following:

Sample space,  S = {1, 2, 3, 4, 5, 6}

In the above sample space, we have

Outcomes greater than 2 = {3, 4, 5, 6}

So, we have

P(greater than 2) = n(Outcomes greater than 2)/n(Sample space)

Substitute the known values in the above equation, so, we have the following representation

P(greater than 2) = 4/6

When evaluated, we have

P(greater than 2) = 2/3

Hence, the probability is 2/3

Answer:

g = 8

Step-by-step explanation:

Hello!

We can solve for g by isolating the variable.

The value of g is 8.

Answer:

\( \sf \: g = 8\)

Step-by-step explanation:

Now we have to,

→ find the required value of g.

The equation is,

→ 2.8(g - 6) + 1.06 = 6.66

Then the value of g will be,

→ 2.8(g - 6) + 1.06 = 6.66

→ 2.8g - 16.8 = 6.66 - 1.06

→ 2.8g - 16.8 = 5.6

→ 2.8g = 5.6 + 16.8

→ g = (22.4)/(2.8)

→ [ g = 8 ]

Hence, the value of g is 8.

The given function is a cubic function. The original graph of a cubic function takes the shape of each of the given graphs. Recall, if a function, f(x) is translated d units downwards, the new function would be f(x) - d. By applying this rule, we can see that the original cubic function was translated 2 units downwards along the vertical axis. Thus, the correct option is the second graph at the top(right)

Answer:

  1/60 gallon

Step-by-step explanation:

You want to know what is left of 4/5 gallon of paint if 3/4 gallon was used to paint a doghouse, and 2/3 of the remaining amount was used to paint a door.

To find the amount remaining we subtract the amount used for the doghouse from the original amount:

  4/5 -3/4 = (16 -15)/20 = 1/20 . . . . . gallon

2/3 of that was used, so 1/3 of it remains:

  (1/3)(1/20 gallon) = 1/60 gallon

There is 1/60 of a gallon of paint left in the can.

Answer:

71 degrees.

Step-by-step explanation:

m < CED = 180 - 152 = 28 degrees ( adjacent angles).

m <BAC = 28 degrees( alternate angles).

m < ACD = 28 + 43 = 71 degrees (external angle theorem).

The equivalent expressions to \(24^{-7}\) are given as follows:

C. \(\left(\frac{1}{24^{-7}}\right)^{-1}\)

F. \((24^3 \times 24^4)^{-1}\)

Equivalent expressions are expressions that have the same value for all possible values of the variables. In other words, equivalent expressions are different ways of writing the same mathematical idea.

The exponent in the denominator can be moved to the numerator with the changed signal, hence:

\(\left(\frac{1}{24^{-7}}\right)^{-1} = (24^7)^{-1}\)

Applying the power of power rule, we multiply the powers, hence:

\((24^7)^{-1} = 24^{-7}\)

When two terms with the same base and different exponents are multiplied, we add the bases and keep the exponents, hence:

\((24^3 \times 24^4)^{-1} = (24^7)^{-1} = 24^{-7}\)

The angle of elevation of the fly's flight path is approximately 57.74 degrees.

In a right triangle, the hypotenuse is the side opposite the right angle. It is always the longest side of the triangle and is the side opposite to the 90 degrees angle. It is also the side that forms the "hypotenuse" of the right triangle.

The Pythagorean theorem is a fundamental result in Euclidean geometry that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. It can be written as c^2 = a^2 + b^2, where a and b are the legs of the triangle and c is the hypotenuse. This theorem can be used to find the length of the hypotenuse of a right triangle when the lengths of the other two sides are known.

Let's call the angle we're trying to find "theta". The horizontal distance is 30 feet, the vertical distance is 32 feet and the height is 9 feet.

Using pythagorean theorem:

$c^2 = a^2 + b^2$

$c = \sqrt{30^2 + 32^2}$ = $\sqrt{900 + 1024}$ = $\sqrt{1924}$

Now we can use the tangent function:

$\tan(\theta) = \frac{opposite}{adjacent} = \frac{32}{30}$

Now we can find the angle, theta, by using the inverse tangent function:

$\theta = \tan^{-1}(\frac{32}{30})$

The angle of elevation of the fly's flight path is approximately 57.74 degrees.

Answer:

4 to 3

Step-by-step explanation:

First, we need to know how many nonfiction books there are and how many mystery books there are

Well, there are 24 mystery books and 18 nonfiction ones

To find the ratio between them, we need to compare how much 18 is to 24

To do this, let's find a common factor of 18 and 24

Both 18 and 24 have a common factor of 6

6 x 3 = 18

6 x 4 = 24

So, we know that there are 4 6's in 24 and 3 6's in 18

That means the ratio of 24 to 18 is the same as 4 to 3

Because 18 is 3 fourths of 24

So, the ratio of mystery books to nonfiction ones is 4:3

Answer:

4 to 3

Step-by-step explanation:

No.of mystery books= 24

No.of non - fiction = 18

Ratio= 24:18 (or) 24/18

Simplification of 24/18 is 4/3 (or) 4 to 3

Answer:

AB = 42.30 m

Step-by-step explanation:

What we are asked to do is to simply find the length of AB.

Since both triangles are similar, therefore their corresponding sides would be proportional to each other.

Thus:

92/82.8 = 47/AB

Cross multiply

92*AB = 82.8*47

92*AB = 3,891.6

AB = 3,891.6/92

AB = 42.30 m(nearest hundredth)

Answer:

anyone can be greater not only x it depends upon the value of x ,yStep-by-step explanation:

The equation of the straight line joining A to B is y = (1/2)x + 3, the equation of the straight line joining B to C is y = (1/2)x + 3, and A, B, and C are collinear.

What are collinear points?

Collinear points are three or more points that lie on the same straight line. In other words, if three points A, B, and C are collinear, then there exists a straight line that passes through all three points. To determine if three or more points are collinear, we can find the slope of the line that passes through any two of the points. If the slope is the same for all possible pairs of points, then the points are collinear. Otherwise, they are not collinear.

a) To find the equation of the straight line joining A to B, we can use the slope-intercept form of the equation of a line:

y = mx + b

where m is the slope of the line, and b is the y-intercept.

The slope of the line passing through A and B is:

m = (y₂ - y₁) / (x₂ - x₁)

where (x₁, y₁) = (-8, -1) and (x₂, y₂) = (-4, 1).

m = (1 - (-1)) / (-4 - (-8)) = 2/4 = 1/2

To find the y-intercept, we can use the point-slope form of the equation of a line:

y - y₁ = m(x - x₁)

where (x₁, y₁) = (-8, -1) and m = 1/2.

y - (-1) = (1/2)(x - (-8))

y + 1 = (1/2)(x + 8)

y = (1/2)x + 3

Therefore, the equation of the straight line joining A to B is y = (1/2)x + 3.

b) To find the equation of the straight line joining B to C, we can use the same method:

m = (y₂ - y₁) / (x₂ - x₁)

where (x₁, y₁) = (-4, 1) and (x₂, y₂) = (12, 9).

m = (9 - 1) / (12 - (-4)) = 8/16 = 1/2

Using point-slope form with the point (x₁, y₁) = (-4, 1) and slope m = 1/2:

y - 1 = (1/2)(x - (-4))

y - 1 = (1/2)x + 2

y = (1/2)x + 3

Therefore, the equation of the straight line joining B to C is y = (1/2)x + 3.

c)  From the equations of the lines joining A to B and B to C, we can see that both lines have the same slope of 1/2. This implies that the three points A, B, and C are collinear, i.e., they lie on the same straight line.

The regression equation is y = 14.57 + 2.22x₁ + 1.73x₂    and   The estimated regression coefficients indicate that the cost of shipping a package is affected by the type of cargo, with an average base cost of $14.57. Fragile shipments cost an additional $2.22 per package, while semi fragile shipments cost an additional $1.73 per package. Durable shipments are the least expensive, with no additional cost.  

We can use the least squares method to estimate the regression equation. The equation is in the form of y = a + b₁x₁ + b₂x₂, where a is the intercept, b₁ is the coefficient for the fragile cargo type, and b₂ is the coefficient for the semi fragile cargo type. We can calculate the coefficients by first calculating the sum of squares of x₁ and x₂, which is 4. The coefficient for x1 (b1) can be calculated by:

 b1 = (∑xy1 - (∑ x₁∑y/n))/(∑ x₁₂ - (∑ x₁²/n))

= (76.62 - (20*94.07/15))/(17 - (20^2/15))  

= (76.62 - 63.47)/(17 - 400/15)  = 13.15/ (-383.33/15)  = -2.22  

The coefficient for x2 (b2) can be calculated by:  

b2 = (∑xy₂ - (∑x₂∑y/n))/(∑x₂₂ - (∑x₂²/n))

 = (71.59 - (11*94.07/15))/(14 - (11^2/15))  

= (71.59 - 40.47)/(14 - 121/15)  = 31.12/ (-107.33/15)  = 1.73

The intercept (a) can be calculated by:

  a = (∑y/n) - (b₁(∑x₁/n)) - (b₂(∑x₂/n))

    = (94.07/15) - (-2.22(20/15)) - (1.73(11/15))  = 14.57
