The 8% of us states have names that start with the letter w the answer is 8%.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The complete question is:

Of the 50 us states 4 have names that start with the letter w what percentage of us states have names that start with the letter w.

The percentage of the US states that have names that start with the letter W can be calculated:

Percentage = (No of US states starting with W/Total no of US states)×100

Percentage = (4/50)×100

Percentage = 8%

Thus, the 8% of us states have names that start with the letter w the answer is 8%.

Answer:

Step-by-step explanation:

If the large Jar is $4.10 for 540g

and  small jar  $2.81 for 360 g

You need to show how much it cost for 1 g,so you can compare how much it cost per gram. You would divide the total cost by the grams to see how much it is for 1 g.

Large jar.   $4.10/540 = $.0076  for 1 gram

Small Jar.   $2.81/360 =$.0078 for 1 gram

Because the large jar is cheaper to buy per gram, the large jar is the best value for the money.

Answer:

To one decimal place,

y = 16.3 m

Step-by-step explanation:

Using SOHCAHTOA,

In this case we need to use CAH,

WE know the angle = 25 and the hypotenuse H = 18,

so,

y = adjacent

\(cos(angle) = y/H\\y = (18)(cos(25))\\y = 16.3135\\y = 16.3\)

Answer: 16.3 in.

Step-by-step explanation:

use SOH CAH TOA

cos x = adj/hyp

cos 25  = y/18

18 cos 25  = y

y= 16.3

1. The ratio of the shaded area to the area of the whole figure is 3/8 and the ratio of the shaded area to the unshaded area is 3/5.

2. The value of AC/CD. CD/BD, and BD/BC is 8/5, 5/2 and 10/7 respectively.

A ratio is a comparison of two quantities, and it can be expressed in different ways, such as a fraction, a decimal, or a percentage. In this case, we will explore how to find ratios of areas in geometric figures.

Firstly, let's consider the rectangle on the right. To find the ratio of the shaded area to the area of the whole figure, we need to calculate both of these values. The shaded area is a rectangle with dimensions 6 by 2, which means its area is 6 x 2 = 12 square units.

The whole figure is a rectangle with dimensions 8 by 4, so its area is

=> 8 x 4 = 32 square units.

Therefore, the ratio of the shaded area to the area of the whole figure is 12/32, which simplifies to 3/8.

To find the ratio of the shaded area to the unshaded area, we need to subtract the shaded area from the whole area. The unshaded area is a rectangle with dimensions 8 by 2, so its area is

=> 8 x 2 = 16 square units.

Subtracting the shaded area from the whole area gives us

=> 32 - 12 = 20 square units for the unshaded area.

Thus, the ratio of the shaded area to the unshaded area is 12/20, which simplifies to 3/5.

Moving on to the second question, we need to use the figure below to find three ratios: AC/CD, CD/BD, and BD/BC.

Let's start with the first ratio, AC/CD. We know that AC is 8 units long and CD is 5 units long, so

=> AC/CD is 8/5.

Next, CD/BD. We know that BD is 10 units long, so to find CD/BD, we need to subtract the length of AC from the length of BD. AC is 8 units long, so

BD - AC = 10 - 8 = 2 units.

Therefore, CD/BD is 5/2.

Finally, BD/BC. We know that BC is 12 units long, so to find BD/BC, we need to subtract the length of CD from the length of BC. CD is 5 units long, so

=> BC - CD = 12 - 5 = 7 units.

Therefore, BD/BC is 10/7.

Answer:

0.902 = 90.2% probability that the flight would leave on time when it is not raining

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)

In which

P(B|A) is the probability of event B happening, given that A happened.

\(P(A \cap B)\) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Not raining

Event B: Flight leaving on time.

The probability that it will rain is  0.18.

This means that there is a 1 - 0.18 = 0.82 probability of not raining. So \(P(A) = 0.82\)

The probability that it  will not rain and the flight will leave on time is 0.74.

This means that \(P(A \cap B) = 0.74\)

What is the probability that the  flight would leave on time when it is not raining?

\(P(B|A) = \frac{0.74}{0.82} = 0.902\)

0.902 = 90.2% probability that the flight would leave on time when it is not raining

Answer:

The gallon of concentrate was 66% water and 34% syrup.

Step-by-step explanation:

- The first thing is to know how much water and how much syrup have the 5 gallons.

90% water and 10% syrup.

- If we have 5 gallons with the same percentages then:

Where X is the percentage that we do not know.

(90 + 90 + 90+ 90 + 90 + X) / 6 = 86

(90 + 90 + 90+ 90 + 90 + X) = 516

X = 66

The answer is 66% water in the gallon added.

Answer:

C. Percent

Explanation:

per hundred means 1 in 100. percent is referring to the unit that is 1 in 100 of another value

1ex. 1% of 100 (1 percent of 100)

2ex. 49% of 235 (49 percent of 235)

(a) As time goes on and approaches infinity, the level of oxygen in the pond approaches normal, therefore;

The oxygen level will eventually approach its  normal level in the long-run

(b)  The number of weeks after which the oxygen level becomes 60% of its normal level are 0.5, 2 weeks

The rational polynomial function  in which the numerator and denominator have the same power and the coefficient of the highest power are the same indicates that the value of f(t) approaches 1 (normal) as t approaches infinity.

The function with which the oxygen level in the pond can be found is presented as follows;

\(f(t) = \dfrac{t^2-t + 1}{t^2+ 1}\)

f(0) = 1, therefore

The end behavior of the function as the value ot t approaches infinity is therefore the asymptote;

y = 1/1 = 1

The  value of the function f(t) as the value of t approaches infinity is that the f(t) approaches 1, which is the normal level of oxygen in the pond

(b) When the oxygen level is 60%, we get;

\(f(t) = \dfrac{t^2-t + 1}{t^2+ 1} = 60\% = 0.6\)

0.6·(t² + 1) = t² - t + 1

0.6·t² + 0.6 = t² - t + 1

0.4·t² - t + 0.4 = 0

t² - 2.5·t + 1 = 0

Therefore;

(t - 2)·(t - 0.5) = 0

t = 2 or t = 0.5

The times when the oxygen level is 60% is 0.5 and 2 weeks after the organic waste is dumped in the pond.

Answer: its the Laurel girl :)

Step-by-step explanation: I got it right.

Laurel has a less credit-to-debt ratio compared to others so Laurel is most likely to get a good credit card rate option (B) is correct.

It is defined as the amount one party needs to pay to another party as the first party borrowed an amount that will be credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.

We have a statement:

Who is most likely to get a good credit card rate based on their credit-to-debt ratio?

As we know,

Credit-to-debt ratio = Credit card balance ÷ Credit limit

A. Darius has a credit limit of $6,000 and a balance of $1,200.

Credit-to-debt ratio = 1200/6000 = 0.2 or 20%

B. Laurel has a credit limit of $5,000 and a balance of $500.

Credit-to-debt ratio = 500/5000 = 0.1 or 10%

C. Lenore has a credit limit of $10,000 and a balance of $3,500.

Credit-to-debt ratio = 3500/10000 = 0.5 or 35%

D. August has a credit limit of $2,000 and a balance of $300.

Credit-to-debt ratio =  0.15 or 15%

As we can see Laurel has a less credit-to-debt ratio compared to others so Laurel is most likely to get a good credit card rate.

Thus, Laurel has a less credit-to-debt ratio compared to others so Laurel is most likely to get a good credit card rate option (B) is correct.

The third angles in the given cases are:a) 68°b) 79°c) 106°d) 120°e) 64°.

To calculate the third angle of a triangle in which two of the angles are given, we need to use the fact that the sum of all the angles of a triangle is always 180°. Let's use this fact to solve each case given:a) Two angles are given as 47° and 65°. To find the third angle, we subtract the sum of the given angles from 180°.

That is, third angle = 180° - (47° + 65°) = 68°.b) Two angles are given as 24° and 77°. Similar to the previous case, the third angle = 180° - (24° + 77°) = 79°.c) Two angles are given as 56° and 18°. The third angle = 180° - (56° + 18°) = 106°.

d) Two angles are given as 39° and 21°. The third angle = 180° - (39° + 21°) = 120°.e) Each of the two angles is given as 58°. To find the third angle, we subtract twice the value of one of the given angles from 180°. That is, third angle = 180° - (2 × 58°) = 64°.

Direct variation is observed when two quantities increase or decrease by the same factor. This means that if one quantity increases it leads to an increase in the other, also when there is a decrease in one quantity the other quantity also decreases.

Let us now evaluate the graph given below to understand more clearly.

The graph of the direct variation always passes through the origin. From the graph y=2x below, we can see that it's a direct variation graph because it follows the form of direct variation i.e. y=kx where k is the constant.

In this equation y=2x, 2 is the slope of the line and is constant.

Step-by-step explanation:

The conclusion of the hypothesis testing is that; there is not enough evidence to support the claim that the mineral changes a person’s cholesterol level.

Hypothesis testing is defined as the method that is used to find the probability of the hypothesis to be proved in the future on the basis of the small population sample.

Let us first define the hypothesis in this problem;

Null Hypothesis; H₀: μ_d = 0

Alternative Hypothesis; Hₐ: μ_d ≠ 0 (Claim)

The degree of freedom is;

DF = n - 1

DF = 6 - 1

DF = 5

At a significance level of α = 0.10, with a DF of 5, the critical values are ±2.015.

Using a computer software, we can calculate the mean from the attached table as;

D' = ∑d/n

D' = 100/6 = 16.7

Similarly, the standard deviation is calculated from the formula;

S_d = √(n∑d² - (∑d)²)/(n(n - 1))

s_d = √(6.489 - 100²)/(6(6 - 1))

s_d = 25.4

The test statistic is gotten from the formula;

t = (D' - μ_d)/(s_d/√n)

t = (16.7 - 0)/(25.4/√6)

t = 1.610

This is less than the critical value and we fail to reject the null hypothesis and conclude that there is not enough evidence to support the claim that the mineral changes a person’s cholesterol level.
