Answer:

156 were there on the fourth day.

Step-by-step explanation:

125% of the number she received on the previous day

This means that the previous day number is multiplied the 125%/100% = 1.25.

64 responses the first day

This means that the number of responses after x days is given by:

[tex]R(x) = 64(1.25)^x[/tex]

How many were there on the fourth day?

This is R(4). So

[tex]R(4) = 64(1.25)^4 = 156[/tex]

156 were there on the fourth day.

Answer:

1. There is a weak positive correlation.

Step-by-step explanation:

The correlation coefficient shows the relation of points in a data set. It is between 0 and 1 or 0 and -1. If the coefficient is closer to 0 then the correlation is weak. So, since 0.35 is closer to 0 than 1 it must be a weak correlation. Additionally, because it is positive the correlation must also be positive. A positive correlation means that the line of best fit will have a positive slope.

Answer:

  12

Step-by-step explanation:

The square can be completed by adding and subtracting the square of half the linear term's coefficient.

  f(x) = x^2 -8x +(-8/2)^2 +28 -(-8/2)^2

  f(x) = (x^2 -8x +16) +(28 -16)

  f(x) = (x -4)^2 +12

The minimum value of the function is 12, when the squared term is zero.

Answer:

2/52

Step-by-step explanation:

If he took one ace out of 52 cards then it would have been 4/52

but as he's taking 2 aces out of 52 cards it is 2/52

Answer:

[tex]P(AA) =\frac{1}{221}[/tex]

Step-by-step explanation:

Deck contains = 52 cards

Deck contains = 4 Aces

Probability of choosing ace first time

                                                        [tex]= \frac{4}{52}[/tex]

Probability of choosing ace again without replacement

                                                                                 [tex]=\frac{3}{51}[/tex]

Probability of 2 aces without replacement

                                                               [tex]=\frac{4}{52} \times \frac{3}{51}\\\\=\frac{1}{13} \times \frac{1}{17}\\\\=\frac{1}{221}[/tex]

As it is right angled, thus it will be equal to 90.

= 2x + 5 + x + 25 = 90

= 3x + 30 = 90

= 3x = 60

= x = 60/3

= x = 20

Answer:

x = 20°

Step-by-step explanation:

[tex]2x + 5 + x + 25 = 90 \\ 3x + 30 = 90 \\ 3x = 90 - 30 \\ 3x = 60 \\ x = \frac{60}{3} \\ x = 20 \\ [/tex]

Answer:

Logan bought the stocks at $2,750,000

Step-by-step explanation:

So according to the question $3,437,500 is the amount at which 25% interest was made

This means that the original value(100% value) has been increased to 125%(thus 100+25%)

By using ratio and proportion,

If 125%-$3437500

then 100% ={100%/125%}×$3,437,50

=$2,750,000

The term that best describes the point V is (d) the centroid.

The centroid is the centre point of the object. The point in which the three medians of the triangle intersect is known as the centroid of a triangle. It is also defined as the point of intersection of all the three medians. The median is a line that joins the midpoint of a side and the opposite vertex of the triangle.

here, we have,

to determine the point V:

From the figure, we can see that:

The three lines drawn from point V divide the sides of the triangles into equal segments.

Also, the lines from point V are perpendicular to the sides.

The above description represents the definition of a centroid

Hence, the term that best describes the point V is (d) the centroid

The shape from the cross-section resulting from the cut would be a Rhombus

Step-by-step explanation:

Edmentum Plato users!

The shape of the cross-section resulting from the cut is C. Rhombus.

A rhombus simply means a shape that has opposite sides to be parallel and the sides are equal.

Here, the information states that the edges of the object in the diagram are equal in length and that the object is cut by a vertical plane containing A and B and bisecting two of the horizontal edges.

Therefore, the shape of the cross-section resulting from the cut is a rhombus.

Answer:

The number of bacteria after t hours is given by: [tex]y(t) = 100e^{0.3219t}[/tex]

Step-by-step explanation:

Amount of bacteria after t hours:

Is given by the following equation:

[tex]y(t) = ae^{kt}[/tex]

In which a is the initial value and k is the constant of growth.

There are 100 bacteria initially

This means that [tex]a = 100[/tex]. So

[tex]y(t) = ae^{kt}[/tex]

[tex]y(t) = 100e^{kt}[/tex]

500 bacteria five hours later.

This means that [tex]y(5) = 500[/tex]. We use this to find k. So

[tex]y(t) = 100e^{kt}[/tex]

[tex]500 = 100e^{5k}[/tex]

[tex]e^{5k} = 5[/tex]

[tex]\ln{e^{5k}} = \ln{5}[/tex]

[tex]5k = \ln{5}[/tex]

[tex]k = \frac{\ln{5}}{5}[/tex]

[tex]k = 0.3219[/tex]

So

[tex]y(t) = 100e^{kt}[/tex]

[tex]y(t) = 100e^{0.3219t}[/tex]

The number of bacteria after t hours is given by: [tex]y(t) = 100e^{0.3219t}[/tex]

Answer:

The prediction for the population in 2012 will be of 324.9 million.

Step-by-step explanation:

Exponential equation for population growth:

Considering that the population growth varies directly with time, it's value after t years is given by:

[tex]P(t) = P(0)e^{kt}[/tex]

In which P(0) is the initial value and k is the growth rate.

The population of the United States in 1990 was approximately 249 million

This means that [tex]P(0) = 249[/tex], so:

[tex]P(t) = P(0)e^{kt}[/tex]

[tex]P(t) = 249e^{kt}[/tex]

In 2000, 281 million.

2000 - 1990 = 10, so [tex]P(10) = 281[/tex]. We use this to find k.

[tex]P(t) = 249e^{kt}[/tex]

[tex]281 = 249e^{10k}[/tex]

[tex]e^{10k} = \frac{281}{249}[/tex]

[tex]\ln{e^{10k}} = \ln{\frac{281}{249}}[/tex]

[tex]10k = \ln{\frac{281}{249}}[/tex]

[tex]k = \frac{\ln{\frac{281}{249}}}{10}[/tex]

[tex]k = 0.0121[/tex]

So

[tex]P(t) = 249e^{0.0121t}[/tex]

Use this information to predict the population for 2012.

2012 - 1990 = 22, so this is P(22).

[tex]P(22) = 249e^{0.0121*22} = 324.9[/tex]

The prediction for the population in 2012 will be of 324.9 million.

Step-by-step explanation:

[tex]Area = base \times height = 12 \times 8 = 96 \ m^2[/tex]

Answer:

The area of parallelogram is 96 m ².

Step-by-step explanation:

According to the question , we have given a parallelogram with base 12 m and height is 8 m. We need to find the area of parallelogram.

Using Formula

Area of parallelogram = Base × Height

Substitute the values into this formula

Area of parallelogram = 12 m × 8 m

multiply, we get

Area of parallelogram = 96 m²

Therefore, The area of parallelogram is 96 m ².

Answer:
