Suppose Z varies directly with X and inversely with Y where X equals 3Y equals one and Z equals six what is the value of Z when X equals seven and why equals four
Answer:
k = 2
Z = 3.5
Step-by-step explanation:
Z = kX/Y
Where,
X = 3
Y = 1
Z = 6
Find k
Z = kX/Y
6 = k3/1
Cross product
6 * 1 = 3k
6 = 3k
k = 6/3
k = 2
what is the value of Z when X equals seven and why equals four
X = 7
Y = 4
Z = ?
k = 2
Z = kX/Y
= (2*7)/4
= 14/4
= 3.5
Z = 3.5

Hello. I have no idea how to solve this question below about Probability. I would appreciate if you show how to solve it step-by-step. Thank you so much.
Alonzo, Bob, and Casper work bussing tables at a restaurant. Alonzo has a 70% chance, Bob has a 10% chance, and Casper has a 20% chance of bussing tables in the middle area of the restaurant. If Alonzo is bussing tables, he has a 6% chance of breaking a dish. If Bob is bussing tables, he has a 2% chance of breaking a dish. Finally, if Casper is bussing tables, he has a 3% chance of breaking a dish. If there is a broken dish in the middle of the restaurant, what is the probability it was broken by Casper?
The probability the dish was broken by Casper if he bussed tables is;
P(Casper bussing tables and breaking dish) = 0.6%
We are given the three probabilities each for Alonzo, Bob and Casper for bussing tables and also in case any dish should break.
P(Alonzo bussing tables) = 70% = 0.7
P(Bob bussing tables) = 10% = 0.1
P(Casper bussing tables) = 20% = 0.2
P(Alonzo breaking a dish) = 6% = 0.06
P(Bob breaking a dish) = 2% = 0.02
P(Casper breaking a dish) = 3% = 0.03
This is all about independent events as the probability of breaking the dishes does not increase or decrease with the bussing of the tables.
Thus; P(A and B) = P(A) + P(B)
Thus, if a dish is broken, the probability that it was broken by Casper is;
P(Casper bussing tables and breaking dish) = P(Casper bussing tables) × P(Casper breaking a dish)
P(Casper bussing tables and breaking dish) = 0.2 × 0.03
P(Casper bussing tables and breaking dish) = 0.006 or 0.6%

Q6 A man is going to New York for work. He wants
to book a hotel online.
A friend says
"Remember the booking website will show the price in dollars. It will actually cost more
pounds than the price shown, because of the exchange rate.'
The man checks the exchange rate because he thinks his friend is wrong. He thinks that
the number of pounds will be less than the number of dollars shown.
Exchange rate
£1 = $1.24
Who is right,
the man or his friend?
Explain your answer.
Answer:
The man
Step-by-step explanation:
Let's say the hotel cost $12400(just an example...)
So the website will show $12400. And the man needs to pay $12400.
Since one pound is 1.24 dollars, 12400 dollars will be 12400/1.24=10000 pounds.
12400>10000, so the man is right, the number of pounds will be less than the number of dollars shown.
The man is right about the Exchange rate.
what is Exchange Rate?The rate at which one currency will be exchanged for another is known as the exchange rate. The most frequent types of currencies are national currencies,
A currency's relative value expressed in terms of another currency is called an exchange rate (or group of currencies). The exchange rate is a significant economic variable for nations with active international trade, like Australia.
Given:
The Situation is The man's friend told him that " It will actually cost more
pounds than the price shown, because of the exchange rate."
This means the price in pounds is more than dollar.
But the exchange rate is found to be
£1 = $1.24
So, the price in dollar is more than in pounds.
Hence, the Men is correct.

Lucy recently asked the servers at her restaurant to only give straws to customers who request them. She thinks that about half of the customers will ask for straws but hopes that the rate will be less than half. She randomly selects 100 customers and finds that 43 of them ask for a straw. To determine if these data provide convincing evidence that the proportion of customers who will ask for a straw is less than 50%, 150 trials of a simulation are conducted. Lucy is testing the hypotheses: H0: p = 50% and Ha: p < 50%, where p = the true proportion of customers who will ask for a straw. Based on the results of the simulation, the estimated P-value is 0.0733. Using ∝ = 0.05, what conclusion should Lucy reach?
Because the P-value of 0.0733 > Alpha, Lucy should reject Ha. There is convincing evidence that the proportion of customers who will ask for a straw is less than 50%.
Because the P-value of 0.0733 > Alpha, Lucy should reject Ha. There is not convincing evidence that the proportion of customers who will ask for a straw is less than 50%.
Because the P-value of 0.0733 > Alpha, Lucy should fail to reject H0. There is convincing evidence that the proportion of customers who will ask for a straw is less than 50%.
Because the P-value of 0.0733 > Alpha, Lucy should fail to reject H0. There is not convincing evidence that the proportion of customers who will ask for a straw is less than 50%.
Answer:
Because the P-value of 0.0733 > Alpha, Lucy should fail to reject H0. There is not convincing evidence that the proportion of customers who will ask for a straw is less than 50%.
Step-by-step explanation:
To understand this question, you'll have to understand a few terms: the null hypothesis, the alternative hypothesis, the p-value and the signifiance level.
The null hypothesis (H₀) is the assumption that the phenomenon doesn't exist - in this case, it is that the proportion of customers who will ask for a straw is 50%, or due to chance (you can either ask for a straw or not). When doing a statistical test for the existance of a phenomenon, we usually assume the null hypothesis to be true first.
The alternative hypothesis (Hₐ) is the assumption that a phenomenon is true. In this case, it is that that the proportion of customers who will ask for a straw is less than 50%.
The p-value is usually a result you get after performing the statistical test - it's the probability that the observed results are at least as extreme as the results actually observed, assuming that the null hypothesis is true. In this case, assuming that the proportion of customers who will ask for a straw is 50% (the null hypothesis), a p-value of 0.0733 for the observed result of 43 customers means that if the experiment were to be repeated again, then there is a 7.33% chance that 43 customers or less will ask for a straw, assuming the null hypothesis is true. This seems pretty good - assuming the null hypothesis is true, there's only a 7.33% chance that we could have gotten 43 customers or less, which means it may be reasonable to "reject the null hypothesis" (i.e. the alternative hypothesis may be true).
However, in many cases a 7.33% chance may not be low enough, e.g. in this problem, a less than 5% chance (i.e. p < 0.05) is necessary. This required chance for results to be statistically significantly is called the signifiance level, or alpha value, the "the probability of rejecting the null hypothesis when the null hypothesis is in fact true." In scientific journals or depending on the field of study, there may be a generally accepted signifiance level.

6) You decide to buy food for your baseball team. Hamburgers cost $3.50 and hotdogs cost $2.50. After buying 22 items, the total cost is $68. How many hotdogs did you buy? How many hamburgers did you buy?
Answer:
13 hamburgers and 9 hot dogs
Step-by-step explanation:
Answer:
13 hamburgers
9 hotdogs
I see the person that also gave you an answer never explained how they got the answer. I thought you might like an explanation
Step-by-step explanation:
Let x = no. of hamburgers
y = no. of hotdogs
(1) x + y = 22 (2) 3.5x + 2.5y = 68
y = 22 - x 35x + 25y = 680
35x + 25(22 - x) = 680
35x + 550 - 25x = 680
10x + 550 = 680
10x = 130
x = 13 hamburgers
y = 22 - x = 22 - 13 = 9 hotdogs

The probability of number 6 landing face up is 1/6.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
We have roll a die with number 1 to 6.
So, the possible outcome
{1, 2, 3, 4, 5, 6}
Then, the probability of number 6 landing face up
= 1 / 6
Hence, the probability is 1/6.

1.4x + 3.5y
help! 6th grade :)
Answer:
Step-by-step explanation:
Simplifying
1.4x + 3.5y = 0
Solving
1.4x + 3.5y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3.5y' to each side of the equation.
1.4x + 3.5y + -3.5y = 0 + -3.5y
Combine like terms: 3.5y + -3.5y = 0.0
1.4x + 0.0 = 0 + -3.5y
1.4x = 0 + -3.5y
Remove the zero:
1.4x = -3.5y
Divide each side by '1.4'.
x = -2.5y
Simplifying
x = -2.5y
how do I simplify 2y > 4
Answer and Step-by-step explanation:
Divide both sides by 2 to get y.
2y > 4
y > 2
