In quadrilateral ABCD m < A= 90°
m 2 C = 50° and m < B = m D.
Find the degree measure of < B.
Answer:
m∠B = 170°
Step-by-step explanation:
Sum of all angles in quadrilateral is 360°:
m∠A + m∠B + m∠C + m∠D = 360°
m∠B = 360° - m∠A - m∠C - m∠D
m∠A = 90°
m∠B = m∠D= 50°
m∠B = 360° - 90° - 50° - 50° = 170°

Answer:
y = 10/3x + 20
Step-by-step explanation:
First, we need to find the slope of the function. We can do that by using two points and inserting them into the slope formula. It can be any two but I'll just pick (3, 30) and (6, 40).
m = y₁ - y₂ / x₁ - x₂
m = 30 - 40 / 3 - 6
m = -10/-3
m = 10/3
Now we know the slope is 10/3.
In slope-intercept form, the y-intercept is the constant at the end of the equation. The table of values tells us that the y-intercept is located at (0, 20). So the equation of the linear function is y = 10/3x + 20.

A dental hygienist is a health-care professional who works alongside a dentist to meet the oral health care needs of patients. Asked by one of her clients who needs to get a cavity filled what the average number of cavities a person gets filled by the time they are 50 years old, the hygienist responds that she will gather and determine not just the average, but also the median and the mode - because she would like to know this information herself. A bit of research turns up the following data table taken from a research project of a graduate student. The graduate student surveyed 20 people aged 50 from around Idaho.
Patient ID# Cavities Filled
1 1
2 8
3 7

a. What is the mean (average) number of cavities a person gets filled by age 50?
b. What is the median number of cavities a person gets filled by age 50?
c. What is the most often an occurring number of cavities filled in this data set?
Answer:
a. The mean number of cavities a person gets filled by the age of 50 is 7.1.
b. The medium number of cavities a person gets filled by the age of 50 is 8.
c. The most occuring number of cavities filled in the data set is 8.
Estimate the product of 2 & 4/11 and 16 & 1/5.

B. about 2 × 14 = 28
C. about 3 × 16 = 48
D. about 3 × 14 = 42
Answer:
a
Step-by-step explanation:
Determine what is closer to 2 4/11.
you would- 4/11 to get 2
you would +6/11 to get 3.
So 2 is closer
Do the same with 16 1/5
16 is closer
therefore, it is 2*16=32

Step-by-step explanation:
Now let's assume that you have a newer toilet that uses 6 L per flush, but you are considering upgrading to a dual-flush toilet. If you flush the toilet four times per day, but three of those times you could use the 3 L flush, how many liters of water would you save in 1 year
Answer: 3,285 Liters
Step-by-step explanation:
In the actual case, all your flushes consume 6 L of water.
You flush 4 times per day, then you consume 4 times 6 L per day, this is:
4*6L = 24 L per day.
And in one year there are 365 days, then in one year you consume:
365*24 L = 8,760 L
Now, if you upgrade the toilet, now per day you use:
one time 6 L and 3 times 3 L
Then in day, you use:
1*6 L + 3*3 L = 6L + 9L = 15L
And in the complete year, you will use 365 times that, which is:
365*15 L = 5,475 L
The amount of water that you would save is equal to the difference between the amount that you use in one year with no upgrade (8,760 L) and the amount that you would use in a year if you upgraded your toilet ( 5,475 L)
The difference is:
D = 8,760 L - 5,475 L = 3,285 L
This means that, in this situation, you would save 3,285 liters of water per year if you upgrade your toilet.

Find the vertex of the parabola. y = negative 4 x squared + 24 x minus 35 a. ( -3, 1) c. ( 3, 1) b. ( -3, -1) d. ( -1, -3)
Answer:
(3, 1)
Step-by-step explanation:
y = -4x² + 24x - 35
Find the vertex by using the formula:
(h, k) → [tex]\displaystyle \Big [ -\frac{b}{2a}, \ f \Big (-\frac{b}{2a} \Big ) \Big ][/tex]In this problem, we have:
a = -4 b = 24 c = -35Using 24 for b and -4 for a, we can substitute these values into the vertex formula:
[tex]\displaystyle -\frac{b}{2a} \rightarrow -\frac{24}{2(-4)} = \frac{-24}{-8} = 3[/tex]The h-value for the vertex is 3.
Now let's plug 3 back into the standard form equation to solve for the k-value of the vertex.
[tex]-4x^2 + 24x - 35 \rightarrow -4(3)^2+24(3)-35 = -36 + 72 - 35 = 1[/tex]The k-value for the vertex is 1.
The vertex of the parabola is (3, 1).
2. Find the common difference and the recursive formula. a. 22, 19, 16, 13, …
Answer:
The common difference d is d = -3
The recursive formula is: [tex]\mathbf{a_n=a_{n-1}-3}[/tex]
Step-by-step explanation:
We need to find the common difference and the recursive formula.
a. 22, 19, 16, 13, …
First we will find common difference
The formula of arithmetic sequence is: [tex]a_n=a_1+(n-1)d[/tex]
where a_n is nth term, a_1 is 1st term and d is the difference
Looking at the sequence we get: a_1=22, a_2=19
Using these values we can find d, the common difference
[tex]a_n=a_1+(n-1)d\\put\:n=2, a_2=19, a_1=22\\19=22+(2-1)d\\19=22+d\\d=19-22\\d=-3[/tex]
So, the common difference d is d = -3
Now, we will find the recursive formula:
The recursive formula is of type: [tex]a_n=a_{n-1}+d[/tex]
We have found common difference d = -3
So, the recursive formula will be:
[tex]a_n=a_{n-1}+d\\a_n=a_{n-1}+(-3)\\a_n=a_{n-1}-3[/tex]
The recursive formula is: [tex]\mathbf{a_n=a_{n-1}-3}[/tex]
Rise over run (-5,2) and (1,-2)
(4,10) and (-2,-5) slope
Answer/Step-by-step explanation:
6. Given, (-5, 2) and (1, -2):
[tex] \frac{rise}{run} = \frac{y_2 - y_1}{x_2 - x_2} [/tex]
[tex] = \frac{-2 - 2}{1 - (-5)} [/tex]
[tex] = \frac{-4}{6} [/tex]
[tex] = \frac{-2}{3} [/tex]
9. Given, (4, 10) and (-2, -5):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_2} [/tex]
[tex] = \frac{-5 - 10}{-2 - 4} [/tex]
[tex] = \frac{-15}{-6} [/tex]
[tex] slope = \frac{5}{2} [/tex]

You and your brother always flip a special golden dollar coin to decide who gets to select the music when the two of you are in the car. The coin has come up heads (in your brother’s favor) on 8 of the last 10 flips.
Do 10 flips provide convincing evidence that your brother is using an unfair coin to gain an advantage?
Yes, the probability of flipping heads with a fair coin is 0.5. He should have gotten heads exactly 5 times.
No, there is no way to determine the probability of flipping heads.
Maybe, if the coin comes up tails on 8 of the next 10 flips, then he is using a fair coin.
No, 10 trials (flips) is not enough evidence to determine if the coin is fair. We would need many, many more flips to determine the true proportion of heads for this coin.
Answer:
No, 10 trials (flips) is not enough evidence to determine if the coin is fair. We would need many, many more flips to determine the true proportion of heads for this coin.
This is the answer Edge 2020
Statement fourth "No, 10 trials (flips) is not enough evidence to determine if the coin is fair. We would need many, many more flips to determine the true proportion of heads for this coin" is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that
shows the happening of the event.
We have:
You and your brother flip a special golden dollar coin to decide who gets to select the music when the two of you are in the car.
As we know the coin has two sides so
The total outcomes = 2
Then the probability of getting hear or tell is 1/2 or 0.5
If the coin has come up heads(in your brother's favor) on 8 of the last 10 flips.
Since the number of flips is too less for the evidence that your brother is using an unfair coin to gain an advantage.
Thus, statement fourth "No, 10 trials (flips) is not enough evidence to determine if the coin is fair. We would need many, many more flips to determine the true proportion of heads for this coin" is correct.

Step-by-step explanation:
The first option is not the radius because A is going outside of the circle and it would actually be longer than the radius.
BC is too high up, and it's considered a chord, not the radius.
DE is the diameter, not the radius.
That leaves us with 1 answer remaining.

Greg worked for 4 hours and took two 15 minute breaks if he worked eight hours yesterday how many minutes in brakes did Greg take
Answer: Greg would have taken 4 breaks, you pretty much multiply the breaks by 2 because 4 x 2 is 8 hours and 2 x 2 is 4 breaks. In total he would have taken 4 breaks yesterday for a total of 60 minutes. I hope that this helped you!
