Answer:
A. (3, 4), (-3, 2), (6, 1), (-8, 2)
Step-by-step explanation:
OA. (3, 4), (-3, 2), (6, 1), (-8, 2) - function
OB. (6, 1), (-3, 4), (3, 1), (6,2) - this repeats the x value of 6 to two different y values so it is not a function
OC. (3, 4), (-3, 6), (3, 3), (-8, 2)- this repeats the x value of 3 to two different y values so it is not a function
OD. (3,0), (-3, 3), (6, 1), (-3,5)- this repeats the x value of -3 to two different y values so it is not a function

Answer:
50:1
Step-by-step explanation:
To simplify the ratio 50:1, we find the greatest common divisor of 50 and 1, and then we divide 50 and 1 by the greatest common divisor.
The greatest common divisor that you can use to simplify 50:1 is 1. Which means the answer to ratio 50:1 simplified is:
50:1

At Dunkin Donuts the corn muffins they make represent 40% of the total muffins they bake everyday. On Monday they make 20 corn muffins. How many total muffins did they bake?
Answer:
50 muffins
Step-by-step explanation:
20 : 40%
y : 100%
[tex]\frac{20}{y} :\frac{40}{100}[/tex]
y · 40 = 20 · 100
40y = 2000
40y ÷ 40 = 2000 ÷ 40
y = 50
Answer:
50
Step-by-step explanation:
first you must find out how many muffins are in 1%, that will be .5 muffins which also meens that every 2% there will be 1 muffin. so we do 100 dived by 2 and you will get 50 which is the amount of muffins that will be made
Integers were used in the 15th century by European traders to label barrels of grain or flour. For example, a barrel that was 1 pound too heavy was labeled +1, and a barrel that was 1 pound too light was labeled –1.
A trader checked twenty 50-pound barrels and found the labels to be: five –3s, nine –5s, two +4s, and four –8s. Find the actual total weight of the barrels.

The measure of L in triangle LMN is 38°. The measure of M is 80°. What is the measure of N? A. 62° B. 42° C. 118° D. 242°
Answer:
62
Step-by-step explanation:
The sum of the angles in a triangle add to 180
L + M + N= 180
38+ 80 + N = 180
118+ N = 180
N = 180-118
N = 62

Answer:
A)σ = 15.37 miles per hour
B) σ = 55.10 miles per hour
C) 39.73 miles per hour
Step-by-step explanation:
Formula for standard deviation is;
σ = √(Σ(x - μ)²)/(n - 1)
A) For large wild cats;
μ = Σx/n = (70 + 40 + 30 + 40 + 35 + 35 + 35 + 35 + 10)/9 = 36.67
σ = √((70 - 36.67)² + (40 - 36.67)² + (30 - 36.67)² + (40 - 36.67)² + (35 - 36.67)² + (35 - 36.67)² + (35 - 36.67)² + (35 - 36.67)² + (10 - 36.67)²)/(9 - 1)
σ = √236.1139
σ = 15.37
B) For various birds;
μ = Σx/n = (218 + 106 + 97 + 56 + 66 + 39 + 55 + 32 + 54 + 20 + 25 + 25)/12
μ = 66.0833
σ = √((218 - 66.0833)² + (106 - 66.0833)² + (97 - 66.0833)² + (56 - 66.0833)² + (66 - 66.0833)² + (39 - 66.0833)² + (55 - 66.0833)² + (32 - 66.0833)² + (54 - 66.0833)² + (20 - 66.0833)² + (25 - 66.0833)² + (25 - 66.0833)²)/(12 - 1)
σ = √3035.72
σ = 55.10
C) difference in standard deviations = 55.10 - 15.37 = 39.73 miles per hour

In a certain year. Cairo has a population of 10,400,000. The land area of Cairo is 520 km square kilometers
If the population density (number of people per square kilometer) of Cairo during this year wask people km, what is the value of k?
Answer:
20,000 per sq. km.
Step-by-step explanation:
In this question, the variable k represents the total number of people in a single square km. Since we are provided both the total number of the population and the total square kilometers of the land, we can calculate the value of k by dividing the population size by the total land. Therefore, the calculation would be the following...
[tex]\frac{10,400,000 people}{520km^{2} }[/tex] = k
20,000 per sq. km. = k
Finally, we can see that the value of k is 20,000 per sq. km.

Find the zeros of y = x2 - 6x – 4 by completing the square.
O A. x = 3 + 5
B. X = +3
C. X = 3 + 13
D. x.-3113
Answer:
√13 + 3 = x
-√13 + 3 = x
Step-by-step explanation:
y = x² - 6x - 4
0 = x² - 6x - 4
0 + 13 = x² - 6x - 4 + 13
13 = x² - 6x + 9
13 = (x-3)²
±√13 = x-3
±√13 + 3 = x
√13 + 3 = x
-√13 + 3 = x

Henry rolls 2 number cubes numbered 1 through 6 while playing his favorite board game. He will get a second turn if he rolls a sum that is an even number less than 10.
What are Henry's chances of getting a second turn when he rolls the number cubes? (2 points)
Answer:
Step-by-step explanation:
The even numbers less than 10 are
2 which can only be done 1 way: when you roll snake eyes.
4 can be done 3 ways (2,2) (3,1) and (1, 3)
6 can be done 5 ways (2,4) (4,2) (5,1) (1,5) and (3,3)
8 can be done 5 ways (4,4) (2,6)(6,2)(5,3) and (3, 5)
There are 36 ways of throwing the number cubes.
We have a total of 5 + 5 + 3 + 1 = 14 ways

Suppose an urn has six balls, three red, two blue, and one yellow. On any draw from the urn, all balls in the urn are equally likely to be drawn. Suppose that two balls are drawn, in sequence without replacement, that is, the second ball is drawn without replacing the first ball in the urn. What is the probability that the second ball drawn is blue
Answer:
1 / 3
Step-by-step explanation:
Number of balls :
Red, R = 3 ; Blue, B = 2 ; Yellow, Y = 1
Total = 6
From two draws without replacement, probability that 2nd draw is blue :
Possibilities :
P(RB) or P(YB) or P(BB)
P(RB) = 3/6 * 2/5 = 6/30
P(YB) = 1/6 * 2/5 = 2 /30
P(BB) = 2/6 * 1/5 = 2 / 30
HENCE,
P(RB) + P(YB) + P(BB)
6/30 + 2/30 + 2/30 = 10/30 = 1/3

To find:
The value of x.
Solution:
In the given figure it is clear that the angles [tex]\angle ACE[/tex] and [tex]\angle ECB[/tex] are lie on a straight line AB.
[tex]m\angle ACE+m\angle ECB=[/tex] [Linear pair]
[tex](2x+2)^\circ+(5x+3)^\circ=180^\circ[/tex]
[tex](7x+5)^\circ=180^\circ[/tex]
[tex]7x+5=180[/tex]
Subtract 5 from both sides.
[tex]7x=180-5[/tex]
[tex]7x=175[/tex]
Divide both sides by 7.
[tex]x=\dfrac{175}{7}[/tex]
[tex]x=25[/tex]
Therefore, the correct option is B.

The amount that two groups of students spent on snacks in one day is shown in the dot plots below.
Group A
A dot plot titled Group A. A number line going from 0 to 5 labeled Amount in Dollars. There are 0 dots above 0, 5 above 1, 4 above 2, 1 above 3, and 0 above 4 and 5.
Group B
A dot plot titled Group B. A number line going from 0 to 5 labeled Amount in Dollars. There are 0 dots above 0, 3 above 1, 2 above 2, 4 above 3, 0 above 4, and 1 above 5.
Which statements about the measures of center are true? Select three choices.
O The mean for Group A is less than the mean for Group B.
O The median for Group A is less than the median for Group B.
O The mode for Group A is less than the mode for Group B.
O The median for Group A is 2.
O The median for Group B is 3.
Answer:
A, B, and C
not D or E
Step-by-step explanation:
A: the mean is 1.6 for group A compared to 2.5 of group B
B: the median is 1.5 for group A compared to 2.5 of group B
C: the mode is 3 for A and the mode is 5 for B
therefor, abc :)
The three statements that are true about the measures of the centre are:
The median for Group A is 2.
The median for Group B is 3.
The mode for Group A is less than the mode for Group B.
What are the mode, median, and mean?We must tally up every dollar spent and divide it by the number of pupils in each group to determine the mean for each group.
The dot plots show that Group A is expected to have a mean that is lower than Group B because Group A has more values that are less than $2, which will lower the average.
Yet, based just on the dot plots, we cannot be certain of the precise values of the means. The claim "The mean for Group A is less than the mean for Group B" is therefore not always accurate.
When the data are organized in order, the median is the middle value. The dot plots show that Group A's median is 2 and Group B's median is 3, respectively. It follows that the claim "The median for Group A is less than the median for Group B" is untrue.
The value that appears the most frequently is the mode. The dot plots demonstrate that Group A has a mode of 1, while Group B has a mode of 3. The adage "The mode for Group A is less than the mode for Group B" is therefore accurate.

What is the diameter of a hemisphere with a volume of 272\text{ m}^3,272 m
3 , to the nearest tenth of a meter?
Answer:
D = 10.1m
Step-by-step explanation:
We know that the volume of a sphere of radius R is:
V = (4/3)*pi*R^3
where pi = 3.14
A hemisphere is half a sphere, then the volume of an hemisphere is half of the volume of a sphere, then the volume of a hemisphere of radius R is:
V' = (1/2)*(4/3)*pi*R^3
Now, we know that our hemisphere has a volume:
V' = 272m^3
Then we can solve the equation:
272m^3 = (1/2)*(4/3)*pi*R^3
For R.
(we want the diameter, but remember that the diameter is equal to two times the radius, so finding the radius is a good start)
272m^3 = (1/2)*(4/3)*pi*R^3
272m^3 = (4/6)*3.14*R^3
272m^3*(6/4*3.14) = R^3
∛( 272m^3*(6/4*3.14) ) = R = 5.06 m
And the diameter is two times that, so we get:
D = 2*5.06m = 10.12 m
Rounding this to the nearest tenth of a meter (first digit after the decimal dot), we get:
D = 10.1m
