Answer:

Hence, the probability is:

\dfrac{1}{25}

Step-by-step explanation:

The number of chips of different colors in Vicky's bag is shown below:

5 blue chips   11 pink chips       9 white chips.

The total number of chips in Vicky's bag are: 25

( since, 5+11+9=25 chips)

Also,

the choosing of the chip is done on the basis of replacement.

This means when one chip is drawn it is put back into the bag and then the other chip is drawn.

Let P denote the probability of an event.

This means that:

P(Blue)=5/25

( Since there are 5 blue chips out of 25 chips)

As the drawing of chip in first draw is independent of the second draw.

Hence, the probability that Vicky takes out a blue chip in both draws is calculated as:

P(Choosing\ Blue\ in\ both\ draw)=P(Blue)\times P(Blue)\\\\P(Choosing\ Blue\ in\ both\ draw)=\dfrac{5}{25}\times \dfrac{5}{25}\\\\P(Choosing\ Blue\ in\ both\ draw)=\dfrac{1}{25}

What is the 32nd term of the arithmetic sequence where a1 = 12 and a13 = -60
Olin [163]

Answer:

The 32nd term of Arithmetic sequence is -174

Step-by-step explanation:

Given: a_1=12, a_{13}=-60

We are given two term of the Arithmetic sequence.

Formula:

a_n=a+(n-1)d

For  a_1=12

a=12

For a_{13}=-60

a+12d=-60

Using two equation solve for a and d

12+12d=-60

1+d=-5

d=-6

We need to find 32nd term

a_{32}=a+31d

a_{32}=12+31(-6)

a_{32}=12-186

a_{32}=-174

Hence, The 32nd term of Arithmetic sequence is -174

Find Distance (4,6) (-4,-3)​
vampirchik [111]

Answer:

\sqrt{145}

Step-by-step explanation:

The distance formula states that the distance between two points (a,b) and (c,d) is \sqrt{(a-c)^2+(b-d)^2}.

The two points we have are (4,6) and (-4,-3). Plugging these numbers into the distance formula, we have

\sqrt{(4-(-4))^2+(6-(-3))^2.

Simplifying with order of operations, first using the distributive property, gives

\sqrt{(4+4)^2+(6+3)^2.

Squaring and adding gives

\sqrt{(4+4)^2+(6+3)^2}=\sqrt{8^2+9^2}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\sqrt{64+81}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\boxed{\sqrt{145}},

which is the answer in simplest form. This also rounds to about 12.04.

So you have to find the relationship between the pumpkin diameter (y) and the number of weeks passed (x) in a table, lets do it taking into account that the equation modeling such behaviour is:
y = 2x + 6, where x is the number of weeks and plus original 6 cm
x                                y                            
week                         diameter
0                                6
1                                8
3                                12
5                                16
10                               26
substitute the x and y values in the equation to see how they fit into it
