Lyn either travels by bus or walks
when she visits the shops.
The probability that she catches
the bus To the shops is 0.2
The probability that she catches
the bus FROM the shops is 0.6

0.2
Walk
a) Complete the tree diagram.
b) Show that the probability that Lyn
walks at least one way is 0.88.​

Answers

I’m forced to write an explanation, sorry for the useless text

The probability tree has been drawn below and the  probability that Lyn

walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks.

What is probability?

The probability of an event occurring is defined by probability.

Do not take underestimate probability it has several uses in daily life whether forecasts like that.

As per the given probability tree,

(a)

The probability in branches adds to 1 thus,

0.2 + probability that she walks to the shop = 1

Probability that she walks to the shop  = 1 - 0.2 = 0.8

The probability in the same branches multiplies as,

The probability that she took a bus to the shop x from the bus she again took the bus.

Similarly, the tree diagram has been drawn below.

(b)

The probability is 0.88 lies in that Lyn walks at least one way 0.88 is when she reaches the shop by bus and from the bus, she walks.

Hence "walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks".

Can someone help me find the value of N in the triangle and round the answer to two decimal places

Answers

Answer:

n ≈ 8.54

Step-by-step explanation:

Reference angle = 30°

Opposite side = n

Adjacent side = 14.8

Apply TOA, which is:

Tan 30 = opp/adj

Tan 30 = n/14.8

Multiply both sides by 14.8

14.8×tan 30 = n

8.54478398 = n

n ≈ 8.54 units (to 2 dp)

Write the equation of each circle
Center (-1,0) and containing the point (2, -4)

A.(x + 1)2 + y2 = 25
B.x2 + (y2 +1)= 25

Answers

Answer:

The equation of the circle is [tex](x + 1)^2 + y^2 = 25[/tex]

Step-by-step explanation:

Equation of a circle:

The equation of a circle of centre [tex](x_c,y_c)[/tex] has the following format:

[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]

In which r is the radius.

Center (-1,0)

This means that [tex]x_c = -1, y_c = 0[/tex]. So

[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]

[tex](x - (-1))^2 + (y - 0)^2 = r^2[/tex]

[tex](x + 1)^2 + y^2 = r^2[/tex]

Finding the radius:

Distance between the radius and the centre and a point of the circle. In this case, point (2,-4). Using the formula for the distance between two points:

[tex]r = \sqrt{(2-(-1))^2+(-4-0)^2} = \sqrt{3^2 + 4^2} = \sqrt{25} = 5[/tex]

So, the equation of the circle is:

[tex](x + 1)^2 + y^2 = 5^2[/tex]

[tex](x + 1)^2 + y^2 = 25[/tex]

A paper company produces 2,985 notebooks in 3 days. How many notebooks can it produce in 11 days?

Answers

Answer:

10080

Step-by-step explanation:

2985÷3=995×11=10080

Answer:

It can produce 32,835 in 11 days.

Step-by-step explanation:

2,985 x 3 =  8,955

2,985 x 3 = 8,955

2,985 x 3 = 8,955

If you add another three, that'll  be 12, so, we'll multiply 2,985 x 2.

2, 985 x 2 = 5,970

Now, Add all of those 4 numbers together,

8,955 + 8,955 + 8,955 + 5,970 = 32,835

Step-by-step explanation:
volume of a rectangular prism is V=LWH
L is length and that is 20
W is width and that is 20
H is height and that is 6
The reason that L and W are 20 is because you would multiply those to get the base, and the base is already given, 400.
Since you know the volume is 2,400, a quick trick is that you divide 2,400/400. That equals 6.
So 20 x 20 x 6 = 2400
