Keiko drove 225 miles using 10 gallons of gas. At this rate, how many gallons of gas would she need to drive 441 miles?
Answer:
19.6 gallons
Step-by-step explanation:
divide 225 by 10 and you get 22.5 this means you are getting 22.5 miles per gallon so all you have to do is divide 441 by 22.5 and you get 19.6 so you are going to need 19.6 gallons to drive 441 miles

A quality control manager at a tortilla company wants to estimate the mean diameter of the tortillas
produced by a certain machine. The manager is deciding between a 90% confidence level and a 95%
confidence level. Compared to a 90% confidence interval, a 95% confidence interval will be,,
a. Narrower and the margin of error would increase
b. Wider and the margin of error would increase
c. Narrower and the margin of error would decrease
d. Wider and the margin of error would decrease
Answer:
C. Narrower and the margin of error would decrease
The required, option b (wider and the margin of error would increase) is the correct answer.
What is the margin of error?In statistics, the margin of error (MOE) is the degree of uncertainty associated with a statistical estimate, usually an estimate of a population parameter based on a sample of data. It is the range of values above and below a sample statistic that is likely to contain the true population parameter with a certain level of confidence.
Compared to a 90% confidence interval, a 95% confidence interval will be wider and the margin of error would increase.
This is because a higher confidence level requires a larger range of possible values to be included in the interval, which in turn leads to a wider interval. With a higher confidence level, the z-score used to calculate the margin of error increases, resulting in a larger margin of error.
Therefore, option b (wider and the margin of error would increase) is the correct answer.

Now, do the same for the second fraction:-
Multiply 5 times 4. The product is 20Add 3. The sum is 23.The denominator stays the same.Thus, the fraction is[tex]\displaystyle\frac{23}{4}[/tex]
Now, the formula for the area is

Use complete sentences to describe the use of an indirect proof.
Answer:
In an indirect proof, instead of showing that the conclusion to be proved is true, you show that all of the alternatives are false.
The indirect proof serves as a powerful tool in mathematical reasoning, allowing mathematicians to establish the truth of statements by strategically exploiting logical inconsistencies within assumed false premises.
An indirect proof is a method in math where you assume the opposite of what you want to prove, then show that this assumption leads to a contradiction or inconsistency.
This means that the opposite assumption must be false, making the original statement true.
It's a way to prove something by showing that its opposite can't be true.
Hence, Indirect proof assumes opposite, leads to contradiction, proving original statement true. Used when direct proof is challenging or problem suits contradiction.

A 1000 kg car moving at 3 ms runs into a 10 kg shopping cart at rest. The shopping cart gets wedged under the car and they stick together. What is their new velocity after the collision?
Their new velocity after the collision is 2.97m/s
Collision of an objectAccording to the law of momentum, the sum of momentum of bodies before the collision is equal to their sum after the collision.
The formula for calculating the momentum of a body is expressed as:
Momentum = mass * velocity
According to the law
m1u1 + m2u2 = (m1 + m2)v
v is the new velocity after the collision
Substitute the given values
1000(3) + 10(0) = (1000+10)v
3000 = 1010v
v = 3000/1010
v = 2.97m/s

What is 60% markup on $18.25?
Compute the total cost of an item you purchased for $18.25, but you now want to resell it for 60% more than what you've paid for it. What is the new cost?
Answer:29.2
Step-by-step explanation:The equation used to add a markup percent to a product is the cost plus the markup percentage multiplied by the cost.
Answer:
$29.20
Step-by-step explanation:
The original price of an item is 100%, so a 60% mark up means that the price will now be 160% of the original price.
160% = 160/100 = 1.6
⇒ 160% of $18.25 = 1.6 × 18.25 = $29.20

Using it's concept, it is found that there is a 0.125 = 12.5% experimental probability that a randomly selected preschooler would choose to read books today.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For an experimental probability, these numbers of outcomes are taken from previous trials.
In this problem, in the previous trial, one out of eight students read a book, hence:

A percentage is a way to describe a part of a whole. The number of French people at the conference is 50.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is given that the total number of people in the conference is 500, while 10% of the participants are french. Therefore, the number of people who are French at the conference can be written as,
Number of French People = 10% of the number of people in the conference

Hey there!
Answer:
336.84%
3200 out of 950 is 336.84%
Solution:
3200 out of 950 is what %?
3200 out of 950 is P%
Equation: Y/X = P%
Solving our equation for P
P% = Y/X
P% = 3200/950
p = 3.3684
Convert decimal to percent:
P% = 3.3684 * 100 = 336.84%
well, if we take 3200 to be the 100%, what is 950 off of it in percentage?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 3200 & 100\\ 950& x \end{array} \implies \cfrac{3200}{950}=\cfrac{100}{x}\implies \cfrac{64}{19}=\cfrac{100}{x} \\\\\\ 64x=1900\implies x=\cfrac{1900}{64}\implies x = 29.6875[/tex]
