Answer:

m<2=60

m<1=120

m<3=120

Step-by-step explanation:

Since m<4=60 that transfers to m<2 also because they are equal. To find the other to angles you have to subtract 60 from 180 because m<1 and m<4 create a straight line that equals 180. That then also transfers to m<3.

Abby is collecting rainfall data. She finds that one value of the data set is a high-value outlier. Which statement must be true?
Abby will use a different formula for calculating the standard deviation.
The outlier will increase the standard deviation of the data set.
The spread of the graph of the data will not change.
Abby will not use the mean when calculating the standard deviation.

Answers

When Abby finds that one value of the data set is a high-value outlier, the true statement is B. The outlier will increase the standard deviation of the data set.

What is an outlier?

It should be noted that an outlier simply means a number in a data set that is further out from the other numbers.

In this case, when Abby finds that one value of the data set is a high-value outlier, the true statement is that the outlier will increase the standard deviation of the data set.

Multiply the binomials:

Answers

Answer:

2y² + y - 15

Step-by-step explanation:

ConceptsMultiplying Binomials:

To multiply binomials, it's best to use the FOIL method, which stands for First, Outside, Inside, and Last. Let's analyze the first, outside, inside, and last term in the binomial we're given by bolding them (in addition, the numbers we bolded are the numbers we multiply; i.e. for the first term, we multiply y and 2y):

First: (y + 3)(2y - 5)Outside: (y + 3)(2y - 5)Inside: (y + 3)(2y - 5)Last: (y + 3)(2y - 5) SolvingSolving the Binomial

Step 1: Apply FOIL method.

[tex](y)(2y) + (y)(-5) + (3)(2y) + (3)(-5)[/tex] [tex]2y^2 -5y +6y -15[/tex]

Step 2: Simplify.

[tex](2y^2)+ (-5y+6y)+(-15)[/tex] [tex]2y^2+y-15[/tex]

Therefore, the answer is 2y² + y - 15.

Answer:2[tex]y^{2}[/tex]+y-15

Step-by-step explanation:

(using distributive property)

(y+3)(2y-5)

y(2y-5)+3(2y-5)

2y^2-5y+6y-15

2y^2+y-15

You can buy 5 cans for green beans at the Village Market for $2.60. You can buy 10 of the same cans of beans at Sam's Club for $5.50. Which place is the better buy?

Answers

Village market
Explanation- each can at village market is $0.52 , and each can at sams club is $0.55

Answer:

Village market

Step-by-step explanation:

What you want to do is times the 5 for 2.60 deal by two since 5x2 is 10, and 10 of cans of green beans at Sam's club is 5.50

5x2=10

2.60

+2.60

----------

5.20 for 10 cans of green beans at the village market

so the cheaper option is to buy 10 cans of green beans at the Village Market which saves you 30 cents than if you were to get them from Sam's Club

Answers

Using statistical concepts, it is found that:

The mean practice time decreases because of the outlier.The median practice time does not change because of the outlier.The range increases because of the oulier.

What are the mean, the median and the range of a data-set?

The mean is the sum of all observations divided by the number of observations.The median is the middle value, the value that separates the upper 50% from the bottom 50%.The range is the difference between the largest value and the smallest.

From their concepts above, we have that the mean and the range are influenced by outliers.

In this problem, the outlier is at the low end, of 15, hence:

The mean practice time decreases because of the outlier.The median practice time does not change because of the outlier.The range increases because of the oulier.

Tell wether the angles are complementary or supplementary. Then find the value of X

Answers

Answer:

The angles are Complementary Angles.

x = 55°

Step-by-step explanation:

the angles are Complementary Angles, because when added, together they form a 90° angle.

•to find the value of x, we form the equation :

⇒90° = x° + (x - 20)°

⇒90 = x + x - 20

⇒90 = 2x - 20

•shifting the 2x to the left side and the 90 to the right side

⇒2x = 90 + 20

⇒2x = 110

•shifting the 2 to the right side

⇒x = 110/2

⇒x = 55° Answer...

Answer:

13/20

Step-by-step explanation:

Note that:
Difference is the same meaning as subtract.

Given:

1 ¼ - ⅗

We first have to change 1 ¼ into a improper fraction:

1 ¼ = 5/4

5/4 - ⅗

Since the denominator are different we have to find common denominator.

25/20 - 12/20

Subtracting: 25 - 12 = 13

13/20

Hence, the different of these fractions is 13/20

Help please!!! At a baseball game, a vender sold a combined total of 236 sodas and hot dogs. The number of sodas sold was three times the number of hot dogs sold. Find the number of sodas and the number of hot dogs sold.

Answers

Answer:

56 hotdogs, 168 sodas.

Step-by-step explanation:

# of sodas sold = s

# of hotdogs sold = h

224 sodas and hotdogs = s + h

3h = s

224 = h + s

Plug in one equation into the other one, like 3h = s into h + s

h + s = 224 and s = 3h so...

h + (3h) = 224

4h = 224

h = 224/4 = 56

56 hotdogs were sold

And since s = 3h...

The number of sodas sold is 3 times 56 = 168 sodas.

56 hotdogs, 168 sodas.

Answer:

56 hotdogs, 168 sodas.

The ice skating rink charges an hourly fee for skating and $3 to rent skates for the day. Gillian rented skates and skated for 3 hours and was charged $21. Which equation represents the cost, c(x), of ice skating as a function of x, the number of hours of skating?

c(x) = 3x + 3
c(x) = 6x + 3
c(x) = 7x + 3
c(x) = 8x + 3

Answers

Answer:

c(x) = 6x + 3

Step-by-step explanation:

c(x) = 6x + 3

he skated for 3 hrs and was charged $21

c(3) = 6(3) + c(3) = 18 + 3

c(3) = 21

correct....so it is c(x) = 6x + 3

p.s please mark this question as brainleist

Thx

answer:

B) c(x) = 6x + 3

explanation:

Gillian rented skates, which costs $3. Now you must subtract that from your total as the next step is to find how much the hourly fee for skating is. $21 - $3 = $18. $18 was the total price for three hours of skating so to find how much the hourly rate is, you divide it by 3. $18/3 = 6. Therefore it is $6 per x amount of hour(s) plus $3 for skates, or simply put, c(x) = 6x +3.
