4, 2, 4, 1, 8, 9, 7, 5, 2, 8
By how much would the range decrease if the number 7 replaced the number 9 in the set?

Answer:

[tex]x = \frac{32}{45}[/tex]

Step-by-step explanation:

Given

[tex]1 * (2\frac{2}{3}) = \frac{1}{2}x + 3\frac{1}{4}x[/tex]

Required

Solve for x

Express all fractions as improper

[tex]1 * \frac{8}{3} = \frac{1}{2}x + \frac{13}{4}x[/tex]

Take LCM

[tex]1 * \frac{8}{3} = \frac{2 + 13}{4}x[/tex]

[tex]\frac{8}{3} = \frac{15}{4}x[/tex]

Cross Multiply

[tex]15x * 3 = 4 * 8[/tex]

[tex]45x = 32[/tex]

Make x the subject

[tex]x = \frac{32}{45}[/tex]

Answer:

-1

Step-by-step explanation:

Any number less than -2 (ex -3, -4, -5) are less than -2

Answer:

-1

Step-by-step explanation:

If you look at a number line, you will see that -1 comes before -2. Since -2 is a negative number, then the lower the number, the greater it is.

Answer:

D. 211

Step-by-step explanation:

180-19=161

161+50=211

19+(211(x)-50)=180

211° is the value of x since if u substitute it u will get your answer note that angle on a straight line is 180°

What is the question?

Step-by-step explanation:

Answer:

Where is the da mn question you stupendous

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

A is not correct because 1 does not equal 1/4 +1/4.

B is correct because 1/4*1 does equal 1/5. (and all the other ones)

C is not correct because 1 does not equal 1/4*1/4

D is not correct because 1/4 does not equal 1-1/4

Answer:

B

Step-by-step explanation:

Answer:

For the first group we have the pairs:

year           population

0                20

1                 80

2                320

3                 1,280

4                 5,120

5                 20,480

Here we can see that the population quadruples each year

(4*20 = 80, 80*4 = 320, 320*4 = 1,280, etc...)

then the population equation is:

P(0) = 20

P(1) = 20*4

P(2) = (20*4)*4 = 20*4^2

We already can see the pattern, then we can write this relationship as:

P(t) = A*(4)^(t)

Where:

t represents time in years, and A is the initial population, that we know it is 20, then:

P(t) = 20*(4)^t

This is the function that represents the table.

B) Now we have a group of 20 squirrels and the population triples each year, with the same reasoning than before we can write the equation that models this situation as:

Q(t) = 20*(3)^t

C) Now, if the initial population of the second group is 40, the equation becomes:

Q(t) = 40*(3)^t

The population by year 3 is given by replacing t by 3, then:

Q(3) = 40*(3)^3 = 1080

And the population of the other group in year 3 is seen in the table, it is 1,280, then the population of the first group is bigger by year 3, and it is greater by:

1,280 - 1,080 = 200

So the first group is larger by 200 squirrels.

Answer:

I don't remember how but you need to work out the frequency, because what you're using is the cumulative frequency.

I took it!

Answer:

15 total miles each hour

Step-by-step explanation:

for this situation and the information given in the question, all we have to do is divide the total amount by 3 (since its 1/3) to get the amount of total miles they drove at, wich is the speed they drove in this case

(sidenote: kinda slow if ya ask me but ok XD)

hope this helps you :D

Answer:

y = [-½]x + [-5]

Step-by-step explanation:

Equation describing how x and y are related can be written in slope-intercept form, y = mx + b.

m = slope = ∆y/∆x

Using two pairs of values from the table, (-2, -4) and (0, -5),

Slope (m) = (-5 - (-4))/(0 - (-2)) = -1/2

m = -½

b = y-intercept = the value of y when x is 0 = -5

b = -5

✔️To write the equation, substitute m = -½ and b = -5 into y = mx + b

Thus:

y = [-½]x + [-5]

Answer:

3x+yl=11

-2x+y=11

y=11-3x

-2x+11-3x=11

-5x=11-11

so x=0

y=11-0

y=11

Answer:

-6

Step-by-step explanation:

Answer:

-6

Step-by-step explanation:

It is asking for the base. The base is -6. The exponent is 2. The exponential form would be -6^2.

I have added an attachment so you can understand better.

They are substituing the exponent b= 5 and the base a= 2

it would be 2x2x2x2x2
