The required total tip paid on $70 is $10.50.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

To complete the ratio table, we need to calculate the tip for each pre-tax bill amount.

Let x be the pre-tax bill amount. Then:

Tip = 0.15x

To find the tip for each pre-tax bill amount in the ratio table, we can substitute the values of x into the formula. For example, for a pre-tax bill of $10:

Tip = 0.15 * 10 = $1.50

Using the same method, we can fill out the ratio table:

Pre-Tax Bill ($) Tip ($)

10 1.50

60 9.00

To find the total tip paid on $70, we need to calculate 15% of $70:

Tip = 0.15 * 70 = $10.50

Therefore, the total tip paid on $70 is $10.50.

Using the concept of fraction and percentage, the percentage increase of the baby at 12 months is 177.7 percent

Percentage increase is a mathematical concept that refers to the increase in a particular value over its initial amount. It is usually expressed as a percentage and is calculated by dividing the increase in the value by the original amount, then multiplying by 100.

In this problem, the data given are;

The percentage increase at 12 months old can be calculated as

percentage increase = [(mass at 12 months - Initial mass) / Initial mass] * 100

percentage increase = [(10 - 3.6) / 3.6] * 100

percentage increase = 1.7 * 100

Percentage increase = 177.7%

Answer:

Due to;

Sampling variability

Step-by-step explanation:

From the question, we have;

The percentage adults experts believe are convinced that it is more enjoyable to be married than single = 70%

The number of adults in the sample of the survey = 1,501 adults

The number of adults that responded that it is more enjoyable to be married than single = 1,126

According to the central limit theorem, the differences in the two samples and the small sizes of the samples compared to the population, the sample means is different from the population mean, therefore, the sample proportion that respond that it is more enjoyable to be married from the new sample will be different from the old sample due sampling variability because as the sample size is so small compared to the population, some samples can contain more of one category in the population than other samples leading to varying proportion

Here is a photo of the answer, it has all the steps!

The probability P(X > 1 | |X| > 1) is approximately 0.5, corresponding to option A.

To find the probability P(X > 1 | |X| > 1), we first need to determine the event |X| > 1. This event implies that the absolute value of X is greater than 1, which means X falls outside the interval (-1, 1).

Since X follows a standard normal distribution with mean 0 and standard deviation 1, the probability of X falling outside the interval (-1, 1) is given by the sum of the probabilities of X being less than -1 and X being greater than 1.

Using a standard normal distribution table or statistical software, we can find these probabilities as follows:

P(X < -1) ≈ 0.1587

P(X > 1) ≈ 0.1587

Now, we can find the conditional probability P(X > 1 | |X| > 1) by dividing the probability of X being greater than 1 by the probability of |X| > 1:

P(X > 1 | |X| > 1) = P(X > 1) / P(|X| > 1)

P(X > 1 | |X| > 1) = 0.1587 / (0.1587 + 0.1587)

P(X > 1 | |X| > 1) ≈ 0.5

Therefore, the probability P(X > 1 | |X| > 1) is approximately 0.5, corresponding to option A.

-18w^2 + 6w - 4

Explanation:

Given the expression (6w — 11w^2)-(4+7w^2)

Open the bracket

6w — 11w^2 - 4 - 7w^2

= -11w^2-7w^2 + 6w -4

= -18w^2 + 6w - 4

Hence the required expansion is -18w^2 + 6w - 4

A rectangular tank 3600 bricks measuring 1/5m by 1/8m by 1/10m into the tank before the water overflows.

To find bricks can be put into the tank before the water overflows,  the volume of water in the tank and then determine the volume of each brick.

The volume of water in the tank  length, width, and depth:

Volume of water = length × width × depth = 3m × 2m × (3/4)m

The volume of each brick:

Volume of each brick = length × width × height = (1/5)m × (1/8)m × (1/10)m

Divide the volume of water in the tank by the volume of each brick:

Number of bricks = (Volume of water) / (Volume of each brick)

Now let's substitute the given values into the formulas and

Volume of water = 3m × 2m × (3/4)m = 9/2 m³

Volume of each brick = (1/5)m × (1/8)m × (1/10)m = 1/400 m³

Number of bricks = (9/2 m³) / (1/400 m³)

= (9/2) / (1/400)

= (9/2) × (400/1)

= 9 × 400 / 2

A. area of larger rectangle: 18x^2

area of smaller rectangle: 8x^2

B. area of shaded region: 10x^2

Step-by-step explanation:

Larger rectangle: A = lw = (6x)(3x) = 18x^2

If the composite functions f(g(x)) and g(f(x)) both equal to x, then the function g is the Inverse function of f.

A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. 

Let us take the Example.

Suppose f(x)= x/4 and g(x)=4x.

Let x=1

then f(g(x))= f(g(1))=f(4)=1

and g(f(x))=g(f(1))=g(1/4)=1

Here, f(g(x))=g(f(x))=1

Therefore , we can say that f(g(x)) and g(f(x)) are inverse of each other.

(a) < a^21 >=< ak > generates a subgroup of the group generated by a, and it is a subgroup of order 2k since

a^48=a^2k,

by Lagrange's theorem.

(b) -< ak > there are 5 subgroups of order 24, and they are generated by a^48, a^24, a^16, a^12, a^8

(c) < ak > there are 4 subgroups of order 48, and they are generated by a^48, a^24, a^16, a^12.

Given a group element a such that a^48. We have to find a divisor k of 48 such that

(a) < a^21 >=< ak >

For the element a^21, k must be a divisor of 21, let's list out the divisors of 21.

Divisors of 21 are 1,3,7,21.

We can choose any of the above divisors as k, hence, we have 4 possible values of k;

k=1,

k=3,

k=7,

k=21.

a^21

generates a subgroup of the group generated by a, and it is a subgroup of order 2k since

a^48=a^2k,

by Lagrange's theorem.

(b) -< ak >

To find the divisors k of 48 such that the subgroup generated by ak has order 24, we use the fact that

ak = a^(48/k),

and since the order of a is 48, we have

a^(48/k) = e

if and only if 48/k is a positive integer.

Let's list out the divisors of 48,

Divisors of 48 are

1,2,3,4,6,8,12,16,24,48.

There are 5 values of k such that 48/k is a positive integer, these are

k=1,

k=2,

k=3,

k=4,

k=6.

So, there are 5 subgroups of order 24, and they are generated by

a^48,

a^24,

a^16,

a^12,

a^8

(c)=< ak >

To find the divisors k of 48 such that the subgroup generated by ak has order 48,

we use the same argument as in (b), but this time we need 48/k to be a positive integer.

Let's list out the divisors of 48,

Divisors of 48 are

1,2,3,4,6,8,12,16,24,48.

There are 4 values of k such that 48/k is a positive integer, these are

k=1,

k=2,

k=3,

k=4.

So, there are 4 subgroups of order 48, and they are generated by

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangle triangle, is a triangle with one right angle, or two perpendicular sides.

The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

A right triangle's hypotenuse is its longest side, its "opposite" side is the one that faces a certain angle, and its "adjacent" side is the one that faces the angle in question.

To describe the sides of right triangles, we utilize specific terminology.

The side opposite the right angle is always the hypotenuse of a right triangle.

Percentages are just fractions with a denominator of 100. To show that a number is a percentage, we place the percent sign (%) next to it. For instance, if you properly answered 68 out of 100 questions on a test, you would have received a 68% grade (68/100).

According to the given information

Let \(P(0)\) be initial population

and K be the growth rate

Then Population of the country after t years

\(P = P(0)e^{Kt}\)

Let x be the present population

2x will be the double of present population

And we know

The growth rate K = 0.02%

So

The value of t could be determined as follows

\(xe^{0.02t}=2x\)

\(e^{0.02}=2\)

\(0.02t=ln(2)\)

Multiply both sides by 1000

0.02t × 1000 = ln(2) × 1000

Refine

20t = ln(2) × 1000

Divide both sides by 20

\(\frac{20t}{20}=\frac{ln(2).1000}{20}\)

t = \(ln(2).500\)

t = 0.693×50

t = 34.65 years
