The required probability is P(A and C) is 0.2 which is represented in the tree diagram.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

The given tree diagram represents an experiment consisting of two trials.

The tree diagram represents an experiment consisting of two trials. In this case, the probability of event A and event C occurring is represented by the intersection of branches A and C in the tree diagram.

This probability can be calculated by multiplying the probability of each individual event together.

As per the given question, we have

P(A) = 0.5

P(C|A) = 0.4

So, P(A and C) = 0.5 × 0.4 = 0.2

Thus, the required probability is P(A and C) is 0.2

P = perimeter

L = length

W = width

Formula for the perimeter of a rectangle = L + L + W + W  or  P = 2L + 2W

You know:

P = 110ft

L = W + 5  [length is 5ft greater than the width]

So plug this into the formula:

P = 2L + 2W             Substitute/plug in (W + 5) for L

110 = 2(W + 5) + 2W           Distribute/multiply 2 into (W + 5)

110 = (2)W + (2)5 + 2W

110 = 2W + 10 + 2W       Combine like terms (2W + 2W)

110 = 4W + 10       Subtract 10 on both sides

110 - 10 = 4W + 10 - 10

100 = 4W     Divide 4 on both sides to get "W" by itself

[tex]\frac{100}{4}=\frac{4W}{4}[/tex]

25 = W        Now that you know the width, plug it into the equation for length

L = W + 5       Plug in 25 for W

L = 25 + 5

L = 30

L = 30 ft

W = 25 ft

PROOF

P = 2L + 2W

110 = 2(30) + 2(25)

110 = 60 + 50

110 = 110

Answer:

52lbs

Step-by-step explanation:

To find out how much weight the black bear lost during hibernation, subtract the weight after hibernation from the weight before hibernation: 265 - 260 = 5 pounds.

To find out how much weight the black bear lost during hibernation, we can use the information that black bears lose 1/5 of their body weight during hibernation. We know that the black bear weighed 265 pounds before hibernation and weighs 260 pounds after hibernation. To calculate the weight loss, we subtract the weight after hibernation from the weight before hibernation: 265 - 260 = 5 pounds. Therefore, the black bear lost 5 pounds while hibernating.

The  algebraic expression can be used to find the nth term of the sequence  is:

[tex]a_n = 5+3n[/tex]

Where, [tex]n\geq 1[/tex] and n is a positive whole number

Solution:

Given sequence is:

8, 11, 14, 17, 20, 23

Let us find the common difference between terms

11 - 8 = 3

14 - 11 = 3

17 - 14 = 3

20 - 17 = 3

23 - 20 = 3

Thus the common difference between successive term and previous term is constant

Thus this is a arithmetic sequence

The formula for nth term term of arithmetic sequence is given as:

[tex]a_n = a_1+(n-1)d[/tex]

Where,

[tex]a_n[/tex] is the nth term of sequence

[tex]a_1[/tex] is the first term of sequence

d is the common difference between terms

Here in this sequence, 8, 11, 14, 17, 20, 23

[tex]a_1 = 8\\\\d = 3[/tex]

Therefore,

[tex]a_n = 8+(n-1)3\\\\a_n = 8+3n -3\\\\a_n = 5+3n[/tex]

Where, [tex]n\geq 1[/tex] and n is a positive whole number

Thus algebraic expression can be used to find the nth term of the sequence is found

Answer: Its width is 6inches.

Step-by-step explanation:

The given information can be used to construct a right angled triangle. Now applying the Pythagoras theorem,

10^2 = W^2 + 8^2

where w represents the width.

100 = w^2 + 64

100 - 64 = w^2

36 = w^2

find the square root of both sides,

6 = w

Therefore, w = 6 inches

Thus the width of the rectangle is 6 inches.

Answer:

|z| = |a + ib| = [tex]\sqrt{a^{2} + b^{2}}[/tex].

Step-by-step explanation:

By the definition of complex numbers the modulus of any complex number z = x + iy is given by |z| = |x + iy| = [tex]\sqrt{x^{2} + y^{2}}[/tex].

Say for example, z = 3 + 4i is a complex number then

|z| = |3 - 4i| = [tex]\sqrt{3^{2} + 4^{2}} = 5[/tex]

In a complex plane modulus of a complex number z = x + iy means the distance of the point (x, iy) from the origin. (Answer)

Final answer:

The algebraic expression for half the quantity of X plus Y is (1/2) × (X + Y) or (X + Y) / 2.

Explanation:

To write an algebraic expression for half the quantity of X plus Y, you start by adding X and Y together. This can be represented as (X + Y). To find half of this quantity, you multiply the sum by 1/2 or divide by 2. Therefore, the algebraic expression that represents half the quantity of X plus Y is (1/2) × (X + Y) or (X + Y) / 2.

19 small mowers and 11 large mowers are sold

Solution:

Let "a" be the number of small mowers sold

Let "b" be the number of large mowers sold

Cost of each small mower = $ 249.99

Cost of each large mower = $ 329.99

30 total mowers were sold

Therefore,

a + b = 30

a = 30 - b ------------- eqn 1

The total sales for a given year was $8379.70

Thus we frame a equation as:

number of small mowers sold x Cost of each small mower + number of large mowers sold x Cost of each large mower = 8379.70

[tex]a \times 249.99 + b \times 329.99 = 8379.70[/tex]

249.99a + 329.99b = 8379.70 ---------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 1 in eqn 2

249.99(30 - b) + 329.99b = 8379.70

7499.7 - 249.99b + 329.99b = 8379.70

80b = 8379.70 - 7499.7

80b = 880

Divide both sides by 80

b = 11

Substitute b = 11 in eqn 1

a = 30 - 11

a = 19

Thus 19 small mowers and 11 large mowers are sold

Answer:

The number 1.256 is  A)rational number.

Step-by-step explanation:

                     [tex]\frac{1256}{1000} =1.256[/tex]

The number 1.256... is a rational number because it can be expressed as a ratio of two integers. It is not an integer, whole number, or irrational number.

The number 1.256 repeated is a rational number because it can be expressed as the ratio of two integers, which fits the definition of a rational number as ratios of integers such as 2/1, 3/4, and so on.

Even though the decimal representation may appear to continue forever, if the pattern of digits repeats indefinitely, it is still rational.

This number is not an integer, whole number, or irrational number, so it does not belong to those sets. An integer is a whole number without any fractional or decimal part, positive or negative, including zero.

Therefore, the correct option that defines the sets to which the number 1.256... belongs is Option A: Rational number.

so

[tex]1\frac{1}{8} (5\frac{3}{4})[/tex]

Convert mixed number to an improper fraction

[tex]1\frac{1}{8}=1+\frac{1}{8}=\frac{1*8+1}{8}=\frac{9}{8}[/tex]

[tex]5\frac{3}{4}=5+\frac{3}{4}=\frac{5*4+3}{4}=\frac{23}{4}[/tex]

substitute

[tex]\frac{9}{8} (\frac{23}{4})=\frac{207}{32}\ hours[/tex]

Convert to mixed number

[tex]\frac{207}{32}=\frac{192}{32} +\frac{15}{32} =6\frac{15}{32}\ hours[/tex]

step 2

How many more hours did April work?

Subtract the hours worked by Carl from the hours worked by April

[tex]\frac{207}{32}-\frac{23}{4}=\frac{207-8*23}{32}=\frac{23}{32}\ h[/tex]

You cant get a number on a 6 sided die higher than 7.

Answer:

(t - 4)(t + 2) = 0  

Step-by-step explanation:

The general formula for a quadratic expression is

y = ax² + bx + c

Your expression is

y = t² - 2t - 8 = 0

By comparison, we see that

a = 1; b = -2; c = -8

1. Find two numbers that multiply to give ac and add to give b.

In this case, find two numbers that multiply to give -8 and add to give -2.

It helps to list the factors of  -8.

They are ±1, ±2, ±4, and ±8

After a little trial and error, you should find the numbers -4 and +2.

-4 × 2 = -8, and -4 + 2 = -2)

2. Rewrite the middle term with those numbers

t² -4t + 2t - 8 = 0

3. Factor the first and last pairs of terms separately

t(t - 4) +2(t - 4) = 0

4. Separate the common factor

The common factor is t - 4.

(t - 4)(t + 2) = 0

Answer:

The correct answer is B

Step-by-step explanation:

If we plug in x=10 to the equation, we get y=47

Since y is positive, A is not an counterexample

Since y is a function of x, C is not an counterexample

Since the graph of y is a parabola, D is not an counterexample
