What is the probability of getting at least 1 red?

The 39th term of the sequence is 200.

Arithmetic sequence or arithmetic progression is the set of numbers for which the difference of any two consecutive numbers in that set will be a constant.

The constant term which is the difference of the two consecutive numbers is called the common difference and is usually denoted by 'd'.

Arithmetic sequence is usually represented as

a, a + d, a + 2d, ........, a + (n - 1)d

The nth term of an arithmetic sequence, aₙ is given by the formula,

aₙ = a + (n - 1) d

where, a is the first term and d is the common difference.

The given sequence is 10, 15, 20, ......

a = 10

d = 15 - 10 = 5

Here, we have to find the 39th term of the sequence.

a₃₉ = 10 + (39 - 1) 5

     = 10 + (38 × 5)

     = 10 + 190

     = 200

Hence, the 39th term of the progression 10, 15, 20,..... is 200.

Answer:

cUse the following equation

Step-by-step explanation:

Because of the way these angles are positioned, they must be equal to 180 together

(2x + 5) + (0.5x + 150) = 180

2.5x + 155 = 180

- 155 - 155

2.5x = 25

2.5x/2.5 = 25/2.5

x = 10

When creating a histogram it is best to create a range for the different variables that are available.

So for the sake of covering all the possible ranges from 1 - 22, let's divide it into 5 categories.

0 - 5        6 - 10   11 - 15   16 - 20   21 - 25

Now that we have set ranges for the different variables, we then find the frequencies.

0 - 5  : 3 

6 - 10 : 2

11 - 15 : 3

16 - 20 : 1

21 - 25 : 3

Now that we have all the values we can then create our histogram.

Answer:

Approximately 32

Step-by-step explanation:

8.1 is closest to 8

4.2 is closest to 4

Thus, you can estimate the product to be 8*4=32

The actual product is 8.1*4.2=34.02, so it's about 2 greater than the estimated product

Answer:

Step-by-step explanation:A. h(x) = √(x-2)

Step-by-step explanation:

To translate a function right by p units and up by q units, the function becomes ...

g(x) = f(x -p) +q

Here, there is no translation upward, but there is a translation of 2 units to the right. The transformed function's name is given as h (not g), so you have ...

(p, q) = (2, 0)

h(x) = f(x -2) +0

h(x) = √(x -2)

The function h(x) , a transformation of the parent function f(x) = √x is √(x+1). Option A is correct option.

The transformation of the function is a function that curves a graph formed by the moving the original graph to left / right / up / down or by expansion or compression.

The transformation is of type horizontal shift when the curve moves to left or right. For y = f(x) , when this curve moves left or right the transformation  is given by y = f(x +c), c > 0 moves y=f(x) to the left by c units

and if c < 0 , moves  y =f(x) to the right by c units

Given that the graph of the f(x) = √x by dotted line and the graph of its transformation h(x) given by solid line.

h(x) is clearly formed by moving f(x) one units to the left as it is moved to left by 1 on origin

Then transformation of y =f(x) moving one unit to left will be given by

y = f(x+1) =√(x+1)

Therefore , transformation h(x) of f(x) is h(x) =√(x+1) and option A is correct option.

Answer: 39.7

Step-by-step explanation:18/55 = 13/x you can get x by solving for it.

Answer:

so you should add 6 to 13 in case to find 19, then add 6 to 19 to get to 25.

so the first is 13 and we keep adding 6 to get to the answer. we do it 47 times. so we have 13+ (6) (47) = 295 which is the 48th term.

The 12th term of the arithmetic sequence13, 19, 25,... is 79.

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same constant ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Given, an arithmetic sequence 13, 19, 25,...

The first term a₁ = 13 and the common difference is = (25 - 19) = (19 - 13) = 6.

We know nth term of an arithmetic sequence is aₙ = a₁ + (n - 1).d.

∴ The 12th term of this arithmetic sequence is a₁₂ = a₁ + (12 - 1).d

a₁₂ = 13 + (12 - 1).6.

a₁₂ = 13 + 11.6

a₁₂ = 13 + 66.

a₁₂ = 79.

The answer is 7.2

The surface area of the actual ramp, including the underside is 16.8 ft²

H1 = 1.2 feet (height of the actual ramp)

and, H2 = 6 cm (height of the model)

The scale factor (k) is:

k = 1.2 feet / 6 cm

k = 0.2 ft/cm

The actual measurements would be:

16cm = 16 cm x 0.2 ft/cm = 3.2 ft

and, 9 cm = 9 cm x 0.2 ft/cm = 1.8 ft,

and, 10 cm = 10 cm x 0.2 ft/cm = 2 ft,

So, the surface area is

Area = 2(0.5 x 3.2 ft x 1.2 ft) + 2(2 ft x 1.8 ft) + (1.8 ft x 3.2 ft)

Area = 16.8 ft²

Hence, the surface area of the actual ramp is 16.8 ft²

Answer:

Length: 20, Width=34

Step-by-step explanation:

Say the length of the width is w, and the length of the length is l. Then, we can establish an equation of W=2L-6. Since the area of a rectangle is W*L, we can substitute W with 2L-6. If we multiply 2L-6 and L, we get [tex]2L^{2} -6L[/tex]=680. We can simplify this equation by dividing everything by 2. We then get [tex]L^{2}-3L=340[/tex]. If we solve for L, we get 20. Now, we plug 20 into the equation, W=2L-6. Since W=2(20)-6, which simplifies to W=40-6 which is 34, we get a width of 34.

The denominator would be x = -3.

Option (A) is correct.

What is the denominator?

A denominator is a bottom number in a fraction. It represents the divisor or the number by which the numerator is being divided.

In this case, the denominator is x^2+6x+9. To find the values of x for which the denominator is equal to zero, we need to set the denominator equal to 0 and solve for x. The equation would be x^2+6x+9=0. By factorizing the denominator we get (x+3)^2=0.

x + 3 = 0

x = -3

Hence, the denominator would be x = -3.

Option (A) is correct.
