Jahnay wants to estimate how many ducks there are in her local park.
One day she puts a non-harmful tag on 20 of the ducks in the park.
The next day she catches 27 ducks and notices that 3 of these have a tag on them.
Work out an estimate for the total number of ducks in her local park.

Answer:

y = 4 * sec x - 1

Step-by-step explanation:

From looking at the graph we can safely determine it's either CSC x or SEC x.

It SEC x because at the origin of it is exactly the same. Now we determine whether it has a vertical/horizontal stretch/shrink and translation shift.

Seeing it is a vertical stretch by 4 and translation 1 down.

I am not sure how to explain it in the more correct way. I have graphed it just to confirm if it is similar to your graph.

The Sam's height after 1 second, form the equation of pathway of Sam's dive into the swimming pool is 11 feet.

The equation of motion is the relation between the distance, velocity, acceleration and time of a moving body.

The pathway of Sam's dive into the swimming pool can be represented by the equation,

[tex]h = -16t^2 + 15t + 12[/tex]

(where t = time in seconds and h = height in feet)

The Sam's height after 1 second is,

[tex]h = -16t^2 + 15t + 12\\h = -16(1)^2 + 15(1) + 12\\h=-16+15+12\\h=11\rm\; ft[/tex]

Thus, the Sam's height after 1 second, form the equation of pathway of Sam's dive into the swimming pool is 11 feet.

The odds in favor of drawing a yellow tile is 11/26

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in to predict how likely events are to happen.

Total tiles 26 in a bag

purple tiles = 15

yellow tiles= 26-15

                  = 11 tiles

So,  the odds in favor of drawing a yellow tile is 11/26.

I did the quiz and that was the answer

The distribution of this graph is Uniform.

The correct option is A.

Based on the provided dot plot, where there are 4 dots above each value from 5 to 10, the distribution can be described as uniform.

Uniform distribution refers to a distribution where the data points are evenly spread out across the range without any noticeable skewness or clustering. In this case, since there are an equal number of dots above each value within the given range, the distribution is uniform.

Answer:

Hi!

The slope of the line is marked as rise over run and in slope intercept form it is mx. We can tell from the way the line is slanting that it is a positive slope. It goes up 1, over 6. So therefore, the slope is 1/6.

The y intercept of the line is -4, which we know because that is where the line and the y axis meet. The y intercept is b in slope intercept form.

The slope intercept form is y = 1/6x -4.

For standard form, we subtract 1/6x from both sides to get

-1/6x + y = -4

Translated function:

y = a(x - h)^2 + k

k is vertical translation (up if positive or down if negative)

3 in your formula so it move up 3

h is horizontal translation (left if positive or right if negative)

1 in your formula so shifted 1 to the right horizontal translation

a is the vertical scaling

it can be either compressed (more narrow) or streched (wider)

a < 0 the graph is either stretched or compressed and also reflected about the x -axis

Probability of apple :

Probability of banana :

Probability of lemon :

Probability of orange :

Probability of pear :

The correct probability distribution for the 50 pieces of fruit, in the order listed is shown in option B. 0.2  0.3  0.12  0.28  0.1

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Total pieces of fruits = 50 pieces

Number of apple pieces = 10

Probability of apple pieces from the whole pieces = 10/50 = 0.2

Number of banana pieces = 15

Probability of banana pieces from the whole pieces = 15/50 = 0.3

Number of lemon pieces = 6

Probability of lemon pieces from the whole pieces = 6/50 = 0.12

Number of orange pieces = 14

Probability of orange pieces from the whole pieces = 14/50 = 0.28

Number of pear pieces = 5

Probability of pear pieces from the whole pieces = 5/50 = 0.1

Hence the correct probability are B. Probability 0.2 0.3 0.12 0.28 0.1.

Step-by-step explanation:

Since they are vertical angles, they are congruent. U set up the equation like this “2x+26=3x+21” and solve for x

subtract 2x from both sides and you’ll get “26=x+21”

subract 21 from both sides and you’ll get “5=x”

now we substitute x for 5!

3(5)+21=

15+21=
