* there is picture down below*
Answer:
ABCD is a kiteProperties:
AB = AD, CB = CD, AC⊥DB, AC is angle bisector of DAB and DCBFind x:
P = 140 2(2x + 7 + 4x +3) = 1406x + 10 = 706x = 60x = 10Find y:
3y - 1 and 28° are complementary3y - 1 = 90° - 28°3y - 1 = 62°3y = 63°y = 21°Find z:
4z and 58° are complementary4z = 90° - 584z = 32°z = 8°Answer:
x=10
y = 21°
z=8°
Step-by-step explanation:
we have
AB = AD, CB = CD,
AC perpendicular to DB, AC is angle bisector of DAB and DCB
Perimeter = 140
2(2x + 7 + 4x +3) = 140
6x + 10 = 70
6x = 60
x = 60/6=10
x=10
again
3y - 1 +28° =90
3y - 1 = 90° - 28°
3y - 1 = 62°
3y = 63°
y = 21°
again
4z+58°=90
4z = 90° - 58
4z = 32°
z=32/4
z=8°

Solve the following inequalities and give the solutions in both set and interval notations.
-x/8 + 8/3 ≥ 3
Given:
The inequality is
[tex]-\dfrac{x}{8}+\dfrac{8}{3}\geq 3[/tex]
To find:
The solution for the given inequality in both set and interval notations.
Solution:
We have,
[tex]-\dfrac{x}{8}+\dfrac{8}{3}\geq 3[/tex]
It can be written as
[tex]-\dfrac{x}{8}\geq 3-\dfrac{8}{3}[/tex]
[tex]-\dfrac{x}{8}\geq \dfrac{9-8}{3}[/tex]
[tex]-\dfrac{x}{8}\geq \dfrac{1}{3}[/tex]
Multiply both sides by -8 and change the inequality sign.
[tex]x\leq -\dfrac{8}{3}[/tex]
It means all the values of [tex]x[/tex] which are less than or equal to [tex]-\dfrac{8}{3}[/tex] are included in the solution set.
Set notation is [tex]\{x|x\leq -\dfrac{8}{3}\}[/tex].
Interval notation is [tex]\left(-\infty,-\dfrac{8}{3}\right ][/tex].
A fair die is a cube with number 1 through 6 on the sides, represented as painted spots. If a fair die is rolled, what is the probability of number 6 landing face up?
Answer:
The First Part is A. 1/6
The Second Part is 1
The Third Part is B. 3
And The Fourth Part is B. Different
Step-by-step explanation:
Just took it. Edg 2021. Hope this helps :) (Da smiley is George, George says hi)
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.

During the two hours of the morning rush from 8 a.m. to 10 a.m., 80 customers per hour arrive at the coffee shop. The coffee shop has a capacity of 60 customers per hour. On average how long does a customer arriving during the morning rush wait to be served
Answer:
The average waiting time is 1/3 hours (or 20 minutes)
Step-by-step explanation:
Given
[tex]T = 2hours[/tex] --- Time
[tex]D = 80\ customers/hr[/tex] --- Arrivals
[tex]C = 60\ customers/hr[/tex] --- Capacity
Required
Determine the average waiting time
The average waiting time (AT) is calculated using the following formula:
[tex]AT = \frac{1}{2} * T * (\frac{D}{C} - 1)[/tex]
This gives:
[tex]AT = \frac{1}{2} * 2 * (\frac{80}{60} - 1)[/tex]
[tex]AT = 1*(\frac{80}{60} - 1)[/tex]
[tex]AT = (\frac{80}{60} - 1)[/tex]
Remove bracket
[tex]AT = \frac{80}{60} - 1[/tex]
Take LCM
[tex]AT = \frac{80-60}{60}[/tex]
[tex]AT = \frac{20}{60}[/tex]
[tex]AT = \frac{1}{3} hr[/tex]
or
[tex]AT = \frac{1}{3} * 60\ mins[/tex]
[tex]AT = 20\ mins[/tex]
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
