1.Find the length s. Round the answer to three decimal places.

Given:

Total number of students = 6

Number of female students = 4

Number of male students = 2

To find:

Total number of outcomes if 3 students are chosen at random (Should i find the probability of something?)

Steps:

To find the total number of outcomes, we need to list the outcomes

Outcomes = {M,M,F} , {M,F,F} , {F,F,F}

Therefore, the total number of outcomes if 3 students are chosen at random is 3, if we don't consider order.

Could you elaborate the question a bit more if i made a mistake of what to find.

Answer:

I'm pretty sure it's 32

Answer:

The absolute minimum value is "[tex]-\frac{21}{4}[/tex]" and the absolute maximum value is "[tex]15[/tex]".

Step-by-step explanation:

Given:

[tex]f(x)=x^2-x-5[/tex]

on,

[tex][0,5][/tex]

By differentiating it, we get

⇒ [tex]f'(x)=2x-1[/tex]

Set [tex]f'(x)=0[/tex]

then,

⇒ [tex]2x-1=0[/tex]

          [tex]2x=1[/tex]

            [tex]x=\frac{1}{2}[/tex] (Critical point)

When x=0,

⇒ [tex]f(x)=-5[/tex]

When [tex]x=\frac{1}{2}[/tex],

⇒ [tex]f(x)=-\frac{21}{4}[/tex] (Absolute minimum)

When [tex]x=5[/tex]

⇒ [tex]f(x)=15[/tex] (Absolute maximum)

Answer: 45 degrees

Step-by-step explanation:

We know that :

[tex]\bigstar \ \ \boxed{\sf{sin\theta = \dfrac{Opposite \ Side}{Hypotenuse}}}[/tex]

From the figure, We can notice that the side which is opposite to θ is 15 units

⇒   Opposite side = 15

We need to find the Length of Hypotenuse using Pythagorean theorem which is :

⊕   (Hypotenuse)² = (1st Leg)² + (2nd Leg)²

⇒   (Hypotenuse)² = (8)² + (15)²

⇒   (Hypotenuse)² = 64 + 225

⇒   (Hypotenuse)² = 289

⇒   Hypotenuse = Square root of 289

⇒   Hypotenuse = 17

[tex]\sf{\implies sin\theta = \dfrac{15}{17}}[/tex]

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

Step-by-step explanation:

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

Answer:

17

Step-by-step explanation:

2a+30 = 4a-4

+4 +4

2a+34 = 4a

-2a -2a

34 = 2a

÷2 ÷2

a=17

Hope this helps! :)

Answer:

A = 17

Step-by-step explanation:

Opposite angles are congruent in a parallelogram

Hence 2a + 30 = 4a - 4

( Note that we've just created an equation that we can use to solve for a)

We now solve for a

2a + 30 = 4a - 4

Add 4 to both sides

2a + 34 = 4a

Subtract 2a from both sides

34 = 2a

Divide both sides by 2

a = 17

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]

have a good day :)

Step-by-step explanation:

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.

There is a compression from the graph of the parent function to have g(x) = (1/2x)^2 or 1/4x^2

Transformation is a process of changing the position of an object on the xy-plane

Given the parent function for a quadratic equation given as h(x) = x²

If you look at g(x), you can see that there is a compression from the graph of the parent function to have g(x) = (1/2x)^2 or 1/4x^2

Compression occur for the coefficient of x^2 that is less than 1

Answer:

13.96units

Step-by-step explanation:

To get the length of CD, we will use the cosine rule as shown:

CD² = DE²+CE²-2(DE)(CE)cos m<E

Substitute the given values

CD² = 14²+9²-2(14)(9)cos71

CD² = 196 + 81 - 252cos71

CD² =277 - 252cos71

CD² = 277 - 82.0431

CD² = 194.95682

CD = √194.95682

CD = 13.96 units

Hence the length of CD of 13.96units

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.

A right angled triangle is drawn to meet the best fit line at any point on the graph,, the point at which the triangle meets the best fit line, provides the values for the rise and run used to calculate the slope, the ris ubsyge cgbage in y values and run is the change in x values ;

Rise, y2 = - 1 ; y2 = 4

Run ; x2 = 3 ; x1 = 1

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.
