Can y’all help me please like bro omg idk

Step-by-step explanation:

hope this helps, happy learning!!!

Answer:

4

Step-by-step explanation:

Answer:

x = 17

Step-by-step explanation:

Nice set up. It's very clear.

Multiply both sides by 3

3(x-2)

===== = 5 *3

  3

Cancel the 3 on the left. Combine the right.

x - 2 = 15

Add 2

x - 2 + 2 = 15 + 2

x = 17

==============

(17 - 2) / 3

15/3

5  

The right hand side is also 5

Answer: I think the answer is 4 because usually when you find the rate of something it means you divided the two numbers or however many numbers you have... So, 12 divided by 3 is 4...  So, 4 hours for each lawn she mows... or something like that... So, 4 lawns per hour...

Final answer is 4 lawns per hour... If this isn't the correct answer i am very sorry... Stay safe and have a great weekend!!! :D

Answer:

4 lawns per hour

Step-by-step explanation:

4 lawns per hour or 1  lawn per 15 mins.

12/3 is the unit rate so 4/1.

Hope this helps plz hit the crown :D

Answer:

[tex]7x\geq 15[/tex]

Step-by-step explanation:

This problem lays out pretty clearly what needs to be done.

First, we know that we are writing an inequality.

Then, it tells us that we need 'the product of x and 7'. A product is the result of multiplication, so we can multiply 7 and x together to get 7x.

Next, it tells us that the product (7x) is at least 15. At least means that the product has to greater than or equal to 15. That clue tells us which inequality symbol will be used.  

Put it all together and:

[tex]7x\geq 15[/tex]

Hope this helped!

Answer:

On a coordinate plane, a line goes through points (0, negative 3) and (6, 0).

Step-by-step explanation:

First, solve for two points which solve the equation and plot these points:

First Point: For

x=0

0−2y=6

−2y=6 then divide it by -2

y=(0.-3)

second point:

x−(2⋅0)=6

x−0=6

x=(6,0)

Answer:

To find the constant of proportionality we use the formula k= y/x so we have k=20/500 =0.04

Step-by-step explanation:

Let R = unit rate

R = (7/8) ÷ 1_1/4

R = (7/8) ÷ (5/4)

R = (7/8) • (4/5)

R = (7/2) • (1/5)

R = 7/10

Answer:

1.

Step-by-step explanation:

The only way to get 3 as an answer to (6-m) is if m were to equal 3. Think about how many numbers can you replace m with to make the statement true. For example, try putting 1 as your m and see if it works. 6-1=3 -> 5=3. as you can see, this statement isnt true. The only solution that would work to make this statement true is one number, 3. Hope this helps.

Answer:

finding slope

Step-by-step explanation:

So slope is the change in y over the change in x, to show (Y/X). So finding the difference or the change usually means you need to subtract which you do to the x and y values. So you subtract the y's and x's and what you get is the change.

Answer:

12 white cars

Step-by-step explanation:

Our ratio is 4:3

16:?

We can determine white cars by dividing 16/4 to find how many more cars we have than our original ratio.

16/4 = 4

3 x 4 = 12

16:12 = 4:3

Kayla had $3,740 x .12 = 448.80 by January.    

Step-by-step explanation:

Answer:

Step-by-step explanation:

They're both ways of expressing the equation of a line. Depending on the information you're given, it's easier to use one or the other. Like if you're given the slope and y intercept, it might be easier to use slope intercept equation. If you're given 2 points on a line, it might be easier to calculate the slope between them and then use the pointslope equation using one of the two points given to find the euqation of the line.

The values are missing in the question. They are : 16.3,12.8,13,32.2,28.1,34.4,46.4,53,15.4,18.2

16.3,12.8,13,32.2,28.1,34.4,46.4,53,15.4,18.2

We calculate sample mean and std deviation from given data.

Sample Mean,    =269.8/10=26.98

Sample Variance,     =1859.496/9=206.610667

Sample std dev,s==√206.610667≈14.373958

We want to test two tailed hypothesis:

: σ=12

: σ≠12

Given: s=14.373958⇒  =206.610667,n=10

Significance level, a=0.1 Degrees of freedom, df=n-1=9

Since this is two tailed test, we need area of α=0.1 on either side of critical value. This means area of 0.05 on right of positive critical value.

Critical values are given by   with 9 degrees of freedom.

We can use chi-square table or following excel commands:

CHISQ. INV(0.95,9)=3.32511284307

CHISQ. INV (0.05,9)=16.9189776046

Critical Values, =3.325  and =16.919

Since this is two tailed test, the decision rule or rejection criteria is:

Reject null hypothesis if test statistic is less than or equal to left critical value OR more than or equal to right critical value, i.e,

Reject    if ≤3.325  OR ≥16.919

Test statistic is given by  =((9)*206.610667)/144=12.913167    

Test statistic, =12.913

since test statistic is between two critical values, we (do not reject ) (i.e, we fail to reject .

Conclusion: There is (not sufficient) evidence to conclude that standard deviation is not equal to 12 .

Alternatively, we can use p-value approach. The decision rule or rejection criteria is: reject null hypothesis if p-value is less than or equal to significance level (α), i.e, reject  if p-value ≤0.1

P-value is twice the (smaller) tail area of test statistic because this is two tailed test. We can use excel function to find this. 2*M IN (CHISQ.DIST (12.913167,9,  TRUE ) 1-CHISQ.DIST 12.913167,9,  TRUE ) =0.333149809868

P-value =0.3331

since p-value is greater than significance level (α),we (do not reject ) (i.e, we fail to reject ).

Conclusion: There is (not sufficient) evidence to conclude that standard deviation is different from 12 .
