Step-by-step explanation:

Step 1: Rewrite the square root

(8^1/3)^x

Step 2: Multiply exponents

8^(x/3)

Remember when exponenting an exponent, you multiply the 2 exponents together.

Answer: The third choice, 8^(x/3)

Step-by-step explanation:

If you were to right the cube root of 8 in fractional exponent form, it would be 8^(1/3).

Now, we have (8)^1/3*x

Given:

Percentage of numbers unlisted = 40% = 0.40

Sample size, n = 5

Let's find the probability that all 5 of the selected houses have unlisted numbers.

To find the probability, we have:

p(numbers unlisted) = 0.40

Hence, we have:

q = 1 - p = 1 - 0.40 = 0.60

For the probability, apply the binomial probability:

0 .

Solving further:

Therefore, the probability that all 5 numbers have unlisted numbers is 0.01024

What is a linear equation ?

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form

Ax + B = 0

e.g. x-10=0. Here, x is a variable, A is a coefficient and B is constant.

The standard form of a linear equation in two variables is of the form

Ax + By = C

e.g. 2x-4y=10. Here, x and y are variables, A and B are coefficients and C is a constant.

Now,

As given linear equation is

Answer:

weight of the kitten last year = 9 ounces

Step-by-step explanation:

Let

x = weight of the kitten last year

Weight of the kitten this year = 2 1/3 * x = 21

7/3*x = 21

7/3x = 21

x = 21 ÷ 7/3

x = 21 × 3/7

= 63/7

x = 9 ounces

weight of the kitten last year = 9 ounces

The probability that exactly one of the coins is a 10p piece is 1/2.

To find the probability that exactly one of the coins is a 10p piece, we can consider the possible outcomes.

There are two coins, and each coin can be either a 10p piece or a non-10p piece. Let's consider the four possible outcomes:

1. Erin's coin is a 10p piece, and Jack's coin is a non-10p piece.

2. Erin's coin is a non-10p piece, and Jack's coin is a 10p piece.

3. Both Erin's and Jack's coins are 10p pieces.

4. Both Erin's and Jack's coins are non-10p pieces.

Since the total amount of the two coins is less than 50p, we can eliminate the third possibility (both coins being 10p pieces).

Now, let's calculate the probability for each of the remaining possibilities:

1. Erin's coin is a 10p piece, and Jack's coin is a non-10p piece:

The probability of Erin having a 10p piece is 1/2, and the probability of Jack having a non-10p piece is also 1/2. Therefore, the probability of this outcome is (1/2) * (1/2) = 1/4.

2. Erin's coin is a non-10p piece, and Jack's coin is a 10p piece:

This is the same as the previous case, so the probability is also 1/4.

3. Both Erin's and Jack's coins are non-10p pieces:

The probability of Erin having a non-10p piece is 1/2, and the probability of Jack having a non-10p piece is also 1/2. Therefore, the probability of this outcome is (1/2) * (1/2) = 1/4.

Now, we sum up the probabilities of the two cases where exactly one of the coins is a 10p piece:

1/4 + 1/4 = 2/4 = 1/2.

#SPJ1

Answer:

Because she found it improves division.

Step-by-step explanation:

The confidence interval about the given mean age is (40.7, 34.3). Since the given mean age of 38.8 years is in the obtained interval, there is no sufficient evidence to conclude that the mean age had changed.

The formula for the confidence interval is

C.I = \(\bar x\) ± z(σ/√n)

Where \(\bar x\) - sample mean; z or z(α/2) - test value; σ - standard deviation of the sample; n - sample size;

Consider the hypothesis,

null hypothesis H0: μ = 38.8

alternate hypothesis Ha: μ ≠ 38.8

It is given that,

sample size n = 32

sample mean \(\bar x\) = 37.5

standard deviation σ = 9.2

Constructing a 95% confidence interval about the mean age:

a) Finding the significance level:

= 1 - (95/100)

= 1 - 0.95

∴ α = 0.05

b) Finding the z-value for the obtained significance level:

z(α/2) = z(0.05/2)

∴ z = 1.96 (From the distribution table)

c) Calculating the lower and upper bounds:

C.I = \(\bar x\)  ± z(σ/√n)

On substituting,

C.I = 37.5 ± (1.96)(9.2/√32)

⇒ 37.5 ± (1.96)(1.626)

⇒ 37.5 ± 3.186(≅3.2)

Upper bound = 37.5 + 3.2 = 40.7

Lower bound = 37.5 - 3.2 = 34.3

Thus, the interval is from 34.3 years to 40.7 years.

Hence the given mean age of 38.8 is included in the interval, the evidence is insufficient to conclude that there is a change in the mean age.

For the given tossing of number cube and its frequency outcome, the probability on landing a number greater than 4 is 18/60.

As given in the question

Total number of tossing a number cube = 60

Number of times greater than 4 comes up = 10 + 8 (frequency of is 10 and frequency of 6 is 8)

⇒Number of times greater than 4 comes up = 18

Probability of getting number greater than 4

=  (frequency of getting 5 and 6) / (total number of trials)

⇒ probability of getting number greater than 4  = 18 / 60                                                                      

Therefore, for the given tossing of number cube and its frequency outcome, the probability on landing a number greater than 4 is 18/60.

For the rectangular floor, Ms. Perea will need 235 tiles to cover her kitchen floor.

What exactly is a rectangle?

A rectangle is a four-sided polygon with four right angles (90-degree angles). It has opposite sides that are equal in length and parallel to each other. The rectangle is a special case of a parallelogram, where the opposite sides are also parallel. The two sides that are equal in length are called the "width" or "short side", while the other two sides are called the "length" or "long side". The area of a rectangle is found by multiplying its length by its width, while its perimeter is found by adding the lengths of all four sides.

Now,

To find the number of tiles Ms. Perea will need to cover the kitchen floor, we can divide the total area of the floor by the area of each tile.

The area of the kitchen floor is given by:

Area = Height x Width = 12.5 ft x 22.5 ft = 281.25 sq ft

The area of each tile is given by:

Area of tile = Length of tile x Width of tile = 1.5 ft x 0.8 ft = 1.2 sq ft

To find the number of tiles required, we can divide the area of the kitchen floor by the area of each tile:

t = Area / Area of tile

Substituting the values, we get:

t = 281.25 sq ft / 1.2 sq ft ≈ 234.375

Since we cannot have a fractional number of tiles, we need to round up to the nearest whole number. Therefore, Ms. Perea will need 235 tiles to cover her kitchen floor.

The equation that can be used to find the number of tiles she will need is:

t = (Height x Width) / (Length of tile x Width of tile)

or

t = (12.5 ft x 22.5 ft) / (1.5 ft x 0.8 ft)

Step-by-step explanation:

Given

PV = 100

With reference angle 60°

hypotenuse (h) = 100

perpendicular (p) = ?

Now

Sin 60° = p/h

√3 / 2 = p / 100

p = √3 * 100 / 2

p = 50√3

Also

With reference angle 30°

hypotenuse (h) = 100

perpendicular (p) = ?

sin 30° = p/h

1/2 = p / 100

p = 100 / 2

p = 50

Expressions can be represented using summations

The series from least to greatest is: \(\sum\limits^6_{k = 0}27(\frac 13)^k\), \(\sum\limits^5_{k = 0}50(\frac 18)^k\) and \(\sum\limits^6_{k = 0}33(\frac 12)^k\)

Start by evaluating the summation expressions

\(\sum\limits^6_{k = 0}27(\frac 13)^k\)

Expand the above expression

\(\sum\limits^6_{k = 0}27(\frac 13)^k = 27 * (\frac 13)^0 + 27 * (\frac 13)^1 + 27 * (\frac 13)^2 + 27 * (\frac 13)^3 + 27 * (\frac 13)^4 + 27 * (\frac 13)^5 + 27 * (\frac 13)^6\)

So, we have:

\(\sum\limits^6_{k = 0}27(\frac 13)^k = 27 * 1 + 27 * \frac 13 + 27 * \frac 19 + 27 * \frac 1{27} + 27 * \frac 1{81} + 27 * \frac 1{243} + 27 * \frac 1{729}\)

Evaluate the sum

\(\sum\limits^6_{k = 0}27(\frac 13)^k = 27 +9 + 3 + 1 + \frac 1{3} + \frac 1{9} + \frac 1{27}\)

Evaluate the sum

\(\sum\limits^6_{k = 0}27(\frac 13)^k = 40\frac {13}{27}\)

\(\sum\limits^6_{k = 0}27(\frac 13)^k \approx 40.4815\)

Also, we have:

\(\sum\limits^5_{k = 0}50(\frac 18)^k\)

Expand the above expression

\(\sum\limits^5_{k = 0}50(\frac 18)^k = 50(\frac 18)^0 + 50(\frac 18)^1 +50(\frac 18)^2+50(\frac 18)^3 +50(\frac 18)^4 +50(\frac 18)^5\)

Evaluate the exponents

\(\sum\limits^5_{k = 0}50(\frac 18)^k = 50 + 50(\frac 18) +50(\frac 1{64})+50(\frac 1{512}) +50(\frac 1{4096}) +50(\frac 1{32768})\)

Evaluate

\(\sum\limits^5_{k = 0}50(\frac 18)^k \approx 57.143\)

Also, we have the following expression

\(\sum\limits^6_{k = 0}33(\frac 12)^k\)

Expand the above expression

\(\sum\limits^6_{k = 0}33(\frac 12)^k = 33(\frac 12)^0 +33(\frac 12)^1 +33(\frac 12)^2 +33(\frac 12)^3 +33(\frac 12)^4 +33(\frac 12)^5 +33(\frac 12)^6\)

Evaluate the expression

\(\sum\limits^6_{k = 0}33(\frac 12)^k = 65.484375\)

Rewrite the three expressions

\(\sum\limits^6_{k = 0}27(\frac 13)^k \approx 40.4815\)

\(\sum\limits^5_{k = 0}50(\frac 18)^k \approx 57.143\)

\(\sum\limits^6_{k = 0}33(\frac 12)^k = 65.484375\)

So, the series from least to greatest is:

\(\sum\limits^6_{k = 0}27(\frac 13)^k\), \(\sum\limits^5_{k = 0}50(\frac 18)^k\) and \(\sum\limits^6_{k = 0}33(\frac 12)^k\)

Distance between two points is the magnitude of the distance you travelled without regarding to the direction.

Let the point at the top of the waterfall is origin, where the value is 0.

Distance from the top of the waterfall to the point where they can swim = 1.5 miles or -1.5 miles since it is down the origin

Distance from the top of the waterfall to the point where they can eat lunch = 1.2 miles or -1.2 miles since it is down the origin

Part A :

When the drone needs to be in opposite distance from you when you are eating lunch, the distance of drone from the top of the waterfall must be 1.2 miles.

Total distance from the place where you eat lunch to the drone = 1.2 + 1.2 = 2.4 miles

Part B :

When the drone needs to be in opposite distance from you when you are swimming, the distance of drone from the top of the waterfall must be 1.5 miles.

Total distance from swimming to the drone = 1.5 + 1.5 = 3

Part C :

The value of 0 represent the top of the waterfall.

Part D :

If you hike down to go swimming, distance travelled = |-1.5| = 1.5 miles

If you hike up from the swimming point to the top of the waterfall, distance travelled = +1.5 miles

Both the distance are same.
