Answer:

1/6

Step-by-step explanation:

Out of these four card choices, for the first pick there are two even cards and four cards in total. This means that on the first pick there is a 2/4=1/2 chance that you pick an even card. On the second pick, if you do not replace the card, then there is 1 even card remaining, and 3 cards in total, leaving a probability of 1/3. Multiplying these two probabilities together, you get an overall chance of 1/6. Hope this helps!

Answer:

Option (2) is the answer.

Step-by-step explanation:

From the figure attached,

AB represents the length of Mr. Ray, ED represents the light post and the mirror was placed at point C.

Here AB = d = 6 feet

CD = w = 32 feet

BC = f = 9 feet

Since both the triangles ABC and EDC are similar, their corresponding sides will be in the same ratio.

[tex]\frac{AB}{DE}=\frac{BC}{CD}[/tex]

[tex]\frac{6}{h}=\frac{9}{32}[/tex]

h = [tex]\frac{6\times 32}{9}[/tex]

h = 21.33 feet

h ≈ 21.3 feet

Therefore, height of the light post is 21.3 feet.

Option (2) is the answer.

Answer:

c. 5

Step-by-step explanation:

In the attached image we can calculate the radius in a very simple way, if we focus on the axis of the "y" we have that there is a distance that would be the diameter of the circle and goes from -2 to 8.

Between -2 and 8, there is a quantity of 10 units, since:

8 + 2 = 10

they are added because we want to know the total distance, therefore the diameter is 10, and we know that the radius is half the diameter, so:

r = d / 2

r = 10/2

r = 5

therefore the radius is 5 units, that is, the answer is c. 5

Answer:

[tex]\sum_{k=0}^{n}2k+1[/tex]

Step-by-step explanation:

Let's take a look at how much is added from one term to the next and see if we can recognize a pattern!

If we start by listing the first number in sequence, 1, we get the familiar list:

1, 3, 5, 7, 9, 11

Of course, this is simply the list of the first six odd numbers. To get the first term, we add the first 1 odd number, to get the second, we add first 2 (1 +3), to get the third, we add the first 3 (1 + 3 + 5), and so on. How do we shorten these sums so we're not writing out dozens of terms as the sequence goes on?

For situations where we're adding up a lot of numbers that follow a predictable pattern, mathematicians came up with something called summation notation, or sigma notation, coming from the Greek S, Σ, short for "sum". Here's a simple example of a sum expressed in sigma notation:

[tex]\sum_{n=1}^{4}n=1+2+3+4[/tex]

Let's break this down. n acts as our counter. [tex]\sum_{n=1}[/tex] sets it to start counting at 1, and tells us to stop counting at n = 4. The [tex]\sum n[/tex] bit tells us what pattern we'll be following, in this case, each step of the way we'll be adding the value of the counter.

So how do we express the sum 1 + 3 + 5 + ... in sigma notation? First, we need an expression that describes the pattern algebraically. Ever odd number is 1 away from an even number, so we can either describe our list with the expression [tex]2k+1[/tex] (if we start at k = 0), or [tex]2k-1[/tex] (if we start at k = 1). I'll choose [tex]2k+1[/tex] for this problem.

We want to start counting at k = 0 , and we can choose whatever we want for our stopping point. Let's call that stopping point n, for the nth term in the series. In sigma notation, we can now write this series in the form

[tex]\sum_{k=0}^{n}2k+1[/tex]

Let's test it out for the first few values to see if it works!

Checks out!

To write the series in summation notation, we have to identify a pattern. After we identify the pattern, we get that the notation is:

[tex]S = \sum_{n = 1}^{\infty} n^2[/tex]

Terms:

From this, we can get a pattern that each term is the square of the index, and the notation is:

[tex]S = \sum_{n = 1}^{\infty} n^2[/tex]

Answer:

Step-by-step explanation:

The event is a red car vehicle. So, the experimental probability would be the ratio between the total number of red car vehicles and the total number of cars.

Notice that there are 22 red vehicles in total, and there are 100 cars in total. So, the ratio is

[tex]P=\frac{22}{100} = \frac{11}{50} = 0.22[/tex]

Therefore, there are 22% of chances that the next vehicle in the lot is a red car.

The sum of the interior angles of a quadrilateral = 360°

Subtract the sum of the given angles from 360, that is

4 th angle = 360° - (56 + 115 + 120)° = 360° - 291° = 69°

There are 9 coins

P (nickel) = number of nickels/ total

                = 5/9

Keeping the coin

We now have 8 coins, 4 nickels and 4 dimes

P (nickel) = number of nickels/ total

                = 4/8 = 1/2

P(nickel, keep, nickel) = 5/9* 1/2 = 5/18=.2777777777

10) n= -7

Step-by-step explanation:

9) v - 15 = -27

Add 15 from both sides

i.e. v - 15 + 15 = -27 + 15

v = -12

10) n + 16 = 9

Subtract 16 from both sides

i.e. n + 16 - 16 = 9 - 16

n = -7

Answer:

-3/4

Step-by-step explanation:

To find the slope of a line, you need to see how much it "rises" over a certain amount of "run". In other words, for a given amount of distance traveled along the x axis, how much it traveled vertically along the y axis. In this line, for every 4 units moved to the right, the line goes up by -3 units. Therefore, the slope of the line is -3/4. Hope this helps!

Answer:

m = -4/5

Step-by-step explanation:

Slope is the difference in y-values/difference in x-values.

Since the graph goes 4 units down and 5 units right, the slope is -4/5.

Answer:

3915 cubic inches

Step-by-step explanation:

Let's individually find the volume of both, and then combine them. For the triangle, we know that the length of the triangular base is 7 inches, the height is 10 inches, and the length of the prism is 29 inches. Therefore, the area of the triangular prism is 7*10*29/2=1015 cubic inches. For the rectangular prism, you simply need to multiply all of the dimensions together, getting 10*10*29=2900 cubic inches. Adding these together, you get a total of 3915 cubic inches. Hope this helps!

Answer:

1520.5 cm³

Step-by-step explanation:

Volume formula for cylinder: V = πr²×h

Radius = 11 ÷ 2

Volume = π × 5.5² × 16

             =1520.5cm³

Answer: 90

Step-by-step explanation: mAB =180° as it is a straight angle

x=180-120= 60°

so,The number should be less than 180 but more than 60, be divisible by 30 and be a 2 digit no.

nos. divisible by 30 between 60 and 180 are 90,120 and 150

But there is only one of these that are 2 digit i. e. 90
