Step-by-step explanation:

Rewrite the expression y^2/3 as a radical expression.

if n is a positive integer that is greater than x and a is a real number or a factor, then aˣ/ⁿ = \(\sqrt[n]{a^x}\)

use the rule to convert y²/₃ to a radical

where a =, x =, and n =.

therefore, the radical expression is \(\sqrt[3]{y^2}\)

The probability of selecting a girl and a boy for the class committee can be calculated by considering the total number of outcomes and the number of favorable outcomes.

Identify the number of girls and boys in the class. In this case, there are 5 girls and 7 boys.

Determine the total number of students in the class. That is 5 + 7 = 12.

Determine the number of ways to select two students from the class.

Here we can use the combination formula, which is written as C(n, r), where n is the total number of items and r is the number of items to be chosen.

In our case, n = 12 (total number of students) and r = 2 (number of students to be selected).

C(12, 2) = 12! / (2!(12-2)!) = 66.

Determine the number of favorable outcomes.

In this case, we want to select one girl and one boy. We multiply the number of girls by the number of boys: 5 x 7 = 35.

To find the probability, we divide the number of favorable outcomes (35) by the total number of outcomes (66):

Probability = Number of favorable outcomes / Total number of outcomes = 35 / 66 = 5/6.

So, the probability of selecting a girl and a boy for the class committee is 5/6.

Answer:

5.44 meters

Step-by-step explanation:

We Know

0.3048 meter = 1 ft

How many ft makes a height of 1.66m?

We Take

1.66 ÷ 0.3048 ≈ 5.44 meters

So, the answer is 5.44 meters.

Answer:

Step-by-step explanation:

The question is incomplete and lacks the required diagram. Find the diagram attached. Here is also the complete question.

"The formula for the area of a parallelogram is A = bh, where b is the base and h is the height. Which simplified expression represents the area of the parallelogram? –4x3 + 14x – 24 square centimeters 2x3 – 6x2 – 14x + 24 square centimeters –4x3 – 14x + 24 square centimeters 2x3 + 6x2 + 14x + 24 square centimeters"

Area of a parallelogram = Base * Height.

Given the height of the parallelogram = (x-4)cm

Base = (2x² + 2x-6) cm

Area of the parallelogram =  (x-4)cm *  (2x² + 2x-6) cm

Area of the parallelogram = (x-4)(2x²+2x-6)

Area of the parallelogram = 2x³+2x²-6x-8x²-8x+24

= 2x³+2x²-8x²-6x-8x+24

=  (2x³-6x²-14x+24)cm²

The probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001

In a series of 36 trials, if the subject is guessing randomly, then the probability of correctly guessing odd or even is 1/2.

Let X be the number of correct guesses in a series of 36 trials. X follows a binomial distribution with parameters n = 36 and p = 1/2.

The probability of guessing more than 20 correct is:

P(X > 20) = 1 - P(X ≤ 20)

Using a binomial distribution table, we can find that P(X ≤ 20) = 0.9999 (rounded to four decimal places).

Therefore: P(X > 20) = 1 - 0.9999 = 0.0001

So the probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001 (rounded to four decimal places).

The equation that results if Kiran squares both sides as his first step is gotten as; x + 2 - 10√(x + 2) + 25 = 121

We want to simplify the expression;

[√(x + 2)] - 5 = 11

Squaring both sides is;

([√(x + 2)] - 5) * ([√(x + 2)] - 5) = 11 * 11

⇒ x + 2 - 10√(x + 2) + 25 = 121

x + 2 - 10√(x + 2) + 25 = 121

The constant differences between the consecutive terms are 2 (a); 2 (b), -3 (c), 7 (d), 1(e), and 6(f).

In math, the constant difference can be defined as the number that defines the pattern of a sequence of numbers. This means that number that should be added or subtracted to continue with the sequence.

Due to this, to determine the constant difference it is important to observe the pattern and find out the number that should be added. For example, if the sequence is 2, 4, 6, 8, there is a difference of 2 between each of the numbers and this is the constant difference.

Answer:

  7 2/3

Step-by-step explanation:

The even number of minus signs cancel, so the problem is an addition problem.

  5 2/5 +2 4/15

The fractions can be added only when they have a common denominator. 15 works for that purpose.

  5 6/15 +2 4/15 = (5 +2) +(6/15 +4/15) = 7 10/15

The fraction 10/15 can be reduced by removing a common factor of 5 from numerator and denominator.

Rounded to the nearest hundredth, the value of y at \(x = 7\) is approximately \(12.78\), according to the concept of linear regression line.

To find the linear regression line for the given data, we can use statistical software or a calculator. The equation of the linear regression line is of the form \(y = mx + b\), where m represents the slope and b represents the y-intercept.

Using the provided data, the linear regression line equation is:

\(\[ y = 1.3642x + 3.2324 \]\)

To find the value of \(y\) at \(x = 7\), we substitute \(x = 7\) into the equation:

\(\[ y = 1.3642(7) + 3.2324 \]\)

Simplifying the equation, we get:

\(\[ y = 9.5494 + 3.2324 \]\[ y = 12.7818 \]\)

In conclusion, the linear regression analysis allows us to determine the relationship between the variables x and y in the given data set. By finding the equation of the linear regression line, we can estimate the value of y for any given x. In this case, the linear regression line equation is \(y = 1.3642x + 3.2324\). By substituting \(x = 7\) into the equation, we find that the estimated value of y is approximately \(12.78\). This analysis provides a useful tool for predicting and understanding the relationship between variables, allowing us to make informed decisions and interpretations based on the data.

6x + 2x - 5= 19

8x -5 = 19

8x = 24

x = 3

Answer:

x = 3

Step-by-step explanation:

6x + 2x - 5 = 19

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, combine like terms:

(6x + 2x) - 5 = 19

(8x) - 5 = 19

Next, isolate the variable, x. First, add 5 to both sides:

8x - 5 (+5) = 19 (+5)

8x = 19 + 5

8x = 24

Next, divide 8 from both sides:

(8x)/8 = (24)/8

x = 24/8

x = 3

I would pick C.

The domain of the function h(t) is 0 ≤ t ≤ 3 since it has the formula h(t) = 5t2 + 15t.

Given,

The function h(t) = 5t2 + 15t will have real values when supplied now.

h(t) ≥ 0

So, h(t) ≥ 0

⇒ −5t² + 15t ≥ 0

factoring, there is

-5t(t - 3) ≥ 0

5t(t - 3) ≤ 0

t(t - 3) ≤ 0

t ≤ 0 and t - 3 ≤ 0

t ≤ 0 and t ≥ 3

If t is less than zero, say -1, then t(t - 3) = -1(-1 - 3) = -1(-4) = 4 ≥ 0

If the value of t is 2, then t(t - 3) = 2(2 - 3) = 2(-1) = -2 ≤ 0.

t(t - 3) = 4(4 - 3) = 4(1) = 4 ≥ 0 for t ≥ 3, let's assume.

The domain of t is 0 ≤ t ≤ 3 because we need t(t - 3) 0.

The derivative function f' for the function f is f'(x) = -10 / (5x+3)^2 and Equation of the line tangent to the graph of f  is 5x+2y+7=0.

Given function:

f(x) = 2/5x+3

a.

f'(x) = d/dx(2/5x+3)

According to power rules:

1/u = -1/u^2

= 2(1/(5x+3)^2) d/dx(5x+3)

= 2*5 / (5x+3)^2

= -10/(5x+3)^2

Hence derivative function f' for the function f is f'(x) = -10 / (5x+3)^2.

b.

(a,f(a)) and a = -1

f(-1) = 2/5(-1)+3

= 2/-5+3

= 2/-2

= -1

point (-1,-1)

slope f'(x) = -10/(5x+3)^2

f'(-1) = -10/(5(-1)+3)^2

= -10/(-2)^2

= -10/4

m = -5/2

Equation of the line is  y - y1 = m(x-x1)

y - (-1) = -5/2(x-(-1)

2(y + 1) = -5x - 5

5x + 2y + 2 + 5 = 0

5x+2y+7=0.

Answer:

Step-by-step explanation:To calculate the savings percentage, we first need to find out the cost of the cardboard required for each box.

For the larger box:

Total Surface Area = 2 * (1926 + 1934.5 + 26*34.5) = 2 * (494 + 655.5 + 897) = 4093 cm²

Cost of cardboard for larger box = 0.502 * 4093 = 2055.986 cents = 20.55986 dollars (rounded to 5 decimal places)

For the smaller box:

Total Surface Area = 2 * (2517 + 2526 + 1726) + 6 * (25-21)* (17-2*1) = 3034 cm²

Note that the additional term in the equation is the surface area of the six sides of the lid and base of the box.

Cost of cardboard for smaller box = 0.502 * 3034 = 1522.268 cents = 15.22268 dollars (rounded to 5 decimal places)

The difference in cost between the larger and smaller boxes is:

20.55986 - 15.22268 = 5.33718 dollars (rounded to 5 decimal places)

The percentage savings can be calculated as follows:

Percentage savings = (difference in cost / cost of larger box) * 100%

= (5.33718 / 20.55986) * 100%

= 25.98%

Therefore, using the smaller box will result in a savings of approximately 26% on cardboard costs for Bathu Sneakers compared to using the normal larger box.
