Answer:

The distance between the two points is 10.3

Step-by-step explanation:

To find the length of the line joining the two points, we are going to use the distance formula

Mathematically, we have this as;

D = √(y2-y1)^2 + (x2-x1)^2

From the question;

(x1,y1) = (-3,4)

(x2,y2) = (2,-5)

Thus, we have it that;

D = √((-5-4)^2 + ((2-(-3)^2

D = √81 + 25

D = √(106)

D = 10.3

Answer:

Two events are independent if the outcome of the first event does not affect the outcome of the second event.

Step-by-step explanation:

two events are independent if the occurrence or outcome of the  first event does not affect the outcome or occurrence of the second event.

for example, if you flip a coin the first time and the outcome is a head and you flip a second time and you get a tail. the occurrence of these two event are independent of each other. Thus they are independent events

two outcomes are dependent if the outcome one event is determined by the outcome of the first event.

Answer:

12m + 24

Step-by-step explanation:

Using the distributive property, distribute 6 to the terms in the parentheses

6(2m + 4)

12m + 24

So, the equivalent expression is 12m + 24

Answer:

35

Step-by-step explanation:

Create a proportion where x is the number of Warrior fans

[tex]\frac{5}{3}[/tex] = [tex]\frac{x}{21}[/tex]

Cross multiply and solve for x

105 = 3x

35 = x

So, there were 35 Warrior fans

Answer:

[tex] \bf\huge warrior \: fans = 35[/tex]

Step-by-step explanation:

finding the warrior fans

⟼ warrior : laker fans = 5 : 3 = x : 21

⟼ 5 : 3 = x : 21

⟼ [tex]\frac{5}{3} \times \frac{x}{21} [/tex]

⟼ x = 5 × 7

⟼ x = 35.

⟼ warriors fans = 35.

∴ laker fans is 21 and warriors fan is 35.

∴ warriors : laker fans = 5 : 3 = 35:21.

Answer:

3

Step-by-step explanation:

3*3=15

3*6=18

3*10=30

Answer:

A

Step-by-step explanation:

SO right off the bat it cannot be c, for they do definatly change.

Next, lets find out how much they change by.

The median would now be 120. Since adding 1 more number would make it just 120. Instead of it being 120+130/2.

This is a decrease of 5. Because we can just subtract normal number by new number: 125-120=5.

Now, the mean is already 500/4. This equals 125.

So lets add 0 to that. So now we must divide it by 1 more number, 4+1=5.

That is 500/5. This equals 100.

This is a decrease of 25. Because we can again subtrasct the normal number by the new number: 125-100=25

That is 5x more of a decrease than the mean.

SO it must be A, since the mean decreased more than the median.

Step-by-step explanation:

y = 5

All sides measure the same So 8y= 40          y = 5

x = 30 degrees

The straight line of 40+40 is a straigth angle of 180 Each angle of equilateral triangle is 60 degrees.So its supplementary is  120.The other 2 angles need to add to 60 (30 each) to sum 180 in a triangle

Answer: Choice C) Emi evaluated (46-78)^2 as -(32)^2

Explanation:

The "46-78" is inside the parenthesis, so the result must also stay in the parenthesis. This means (46-78)^2 would become (-32)^2. The negative must be inside the parenthesis as well. Squaring the "-32" leads to a positive result, so every item being added is positive after the squaring operations are applied.

Answer:

0.4, 0.8, 1.2 ,1.6 ,2.0

Step-by-step explanation:

First we have to find what the question is really asking and get rid of unwanted or not needed information. It is asking to write a numeric sequence for the first 5 minutes of the 30 minutes.

Second we need to find the pattern. So lets divide $12 by 30. That will equal 0.4 a minute.

Last we add 0.4 for each minute. 0.4 is the first, then 0.8 is 2 minutes, then 1.2 and etc.

The numeric sequence is 0.4, 0.8, 1.2 ,1.6 ,2.0

Here we have to divide $12 by 30. That will equal 0.4 a minute.

Now if we add 0.4 for each minutes

So the series be like

0.4 for the first, 0.8 is 2 minute and so on.

Answer:

chickens = 11

pigs = 7

Step-by-step explanation:

this would be solved using simultaneous equation

let c = chicken .

p = pigs

A normal pig and chicken both have 1 head. thus :

c + p = 18 equation 1

A normal pig has 4 legs and a normal chicken has 2 legs. Thus

2c + 4p = 50  equation 2

multiply equation 1 by 2

2c + 2p = 36 equation 3

subtract equation 3 from 2

2p = 14

p = 7

substitute for p in equation 1

c + 7 = 18

c = 11

3/8

Step-by-step explanation:

We want to find out how much each person gets per box, so all we have to do is divide the three boxes by three and the 8 by three to get how much each person gets. When we do that, we get 3/8. Literally, that means each boy gets 3/8 of a box of cereal.
