At a coffee shop, the first 100 customers'
orders were as follows.
Small
Medium
Large
Hot
5
48
22
8
12
5
Cold
What is the probability that a customer ordered
a cold drink given that he or she ordered a large?
Rounded to the nearest percent, [? ]%
The probability of a customer ordering a cold drink given that they ordered a large is 0.1852 or about 18.52%.
Let us find the individual probabilities.
P(Large | Cold) = 5/25 = 0.2 (out of 25 cold drinks, 5 were large)
P(Cold) = (8+12+5)/100 = 0.25 (out of 100 orders, 25 were cold)
P(Large) = (22+5)/100 = 0.27 (out of 100 orders, 27 were large)
Now we can plug these values into Bayes' theorem:
P(Cold | Large) = 0.2 × 0.25 / 0.27
P(Cold | Large) = 0.1852
Therefore, the probability of a customer ordering a cold drink given that they ordered a large is 0.1852 or about 18.52%.

[tex]\frac{1}{3(x-2)}[/tex]
Step-by-step explanation:
Hi there!
We need to multiply the fractions:
[tex]\frac{x+3}{12x}[/tex]×[tex]\frac{4x}{x^{2}+x-6}[/tex]
Before we multiply, we can cancel out and factor the polynomials to make multiplying easier
First, we can factor x²+x-6
1 (in front of +x) is the sum of two numbers and -6 is the product of those numbers
Those numbers are -2 and 3
so when we factor, we get:
(x-2)(x+3)
here are the fractions so far:
[tex]\frac{x+3}{12x}[/tex]×[tex]\frac{4x}{(x+3)(x-2)}[/tex]
we can cancel out x+3 on both fractions
[tex]\frac{1}{12x}[/tex]×[tex]\frac{4x}{x-2}[/tex]
we can also cancel out 4x from both fractions
[tex]\frac{1}{3}[/tex]×[tex]\frac{1}{x-2}[/tex]
now multiply the fractions together
[tex]\frac{1}{3(x-2)}[/tex]
So the first option is your answer
Hope this helps! :)

Answer:
d = 67.5
e = 22.5
Step-by-step explanation:
d + e = 90
d = 3e
Therefore, we can simply divide 90 by 4, which gives us 22.5, and also tells us what e equals. Then, multiply that by 3 to get d.

A start-up company is about to market a new computer printer. It decides to gamble by running commercials during the Super Bowl. The company hopes that name recognition will be worththe high cost of the ads. The goal of the company is that over 40% of the public recognize its brand name and associate it with computer equipment. The day after the game, a pollster contacts 420 randomly chosen adults and finds that 181 of them know thatthis company manufactures printers. Would you recommend that the company continue to advertise during Super Bowls
Reject the null hypothesis and come to the conclusion that there is enough evidence to imply that the percentage of adults who are familiar with the company's name is much more than 40%.
What is the null hypothesis?In order to evaluate whether the percentage of individuals who recognize the company's brand name differs considerably from the company's target of 40%, we must conduct a hypothesis test.
Let p represent the percentage of adults who can name the company's brand. The corporation hopes that more than 40% of adults will recognize its brand name, hence the alternative hypothesis is that p > 0.4.
A one-sample z-test can be used to examine this claim. The test statistic is determined as follows:
[tex]z = \dfrac{(p' - p)} { \sqrt{\dfrac{(p (1 - p)} { n}}}[/tex]
Where p is the null hypothesis value, n is the sample size, and p is the sample proportion.
In this instance, n = 420, p = 0.4, and p' = 181/420 = 0.431. With these values entered into the formula, we obtain:
[tex]z = \dfrac{(0.431 - 0.4)} { \sqrt{(0.4 \times \dfrac{0.6} { 420} }}= 1.65[/tex]
The likelihood of obtaining a z-value of 1.65 or higher is 0.0495 using a basic normal distribution table or calculator (assuming the null hypothesis is true). This is the test's p-value.
When the p-value is less than 0.05, which is considered to be significant (and corresponds to a 95% confidence level), we
Hence, based on this sample of 420 adults, we would advise the company to keep running Super Bowl advertisements as it seems to be succeeding in raising brand recognition among the general public.

Which relation is a function?
o {(4,0),(4,1),(4,2), (4,3)}
o {(7,4), (8,8), (10,8), (10,10)}
o {(-1,3), (-2,6),(0,0),(-2,-2)}
o {(2,2), (1,1),(0,0), (-2,-2)}
Given:
Different relations in the options.
To find:
The relation which is a function.
Solution:
A relation is a function if there exist unique output for each input value. In other words, there exist only one y-value for each x value.
In option A, [tex]y=0,1, 2, 3[/tex] for [tex]x=4[/tex]. So, this relation is not a function.
In option B, [tex]y=8, 10[/tex] for [tex]x=10[/tex]. So, this relation is not a function.
In option C, [tex]y=6, -2[/tex] for [tex]x=-2[/tex]. So, this relation is not a function.
In option D, all x-values are different. So, their exist unique output for each input value. It means this relation is a function.
Therefore, the correct option is D.
The number of Roberto’s baseball cards is ¾ the number of David’s cards If Roberto gives ½ of his cards to David, what will be the ratio of Roberto’s cards to David’s cards? please help me. I need it to step by step equations!!!!
Answer:
1/4, 0.25
Step-by-step explanation:
Answer:
3/11
Step-by-step explanation:
Let Roberto's cards be x.
Let David's cards be y
x = (3/4) y
Roberto gives half his cards away which is 1/2*(3/4) = 3/8
David's new amount after the gift = 1/2(3/4)y + y = 3/8y+y=3y/8+8y/8 = 11y/8
So the ratio is Roberto / David = (3/8) // (11/8)
Roberto to David = 3/8 // 11.8 which you now invert and multiply the denominator
Roberto to David = 3/8 * 8/11 = 3/11

Answer:
x=10
Step-by-step explanation:
To solve for x, you need to draw an imaginary line connecting the right end of side x to the left side with length 15. This forms a triangle with side lengths 6 and 8, and hypotenuse x. Using the Pythagorean Theorem to solve for x, we get 6^2 + 8^2 = x^2, 36 + 64 = 100, [tex]\sqrt{100}[/tex] = 10.
Answer:
It's 10
Step-by-step explanation:
C^2=A^2+B^2blank
C=√(A^2+B^2)
If c is x and a and b are the side lengths the we can use Pythagoras's theorem to calculate the length of the line. A=6 B=8 and in the end when you calculate all that doohickey stuff you get x=10
