D. the correct inequality is not listed
Answers
Answer:
c
Step-by-step explanation:
Answer:
C. 6x - y < -3Step-by-step explanation:
The graphed inequality shows that:
The function is increasing, so it has a positive slope, shaded region is to the left of the dashed line, so it should have > sign after y.Above information lets us build the inequality:
y > ax + b, where a> 0Now lets verify the options:
A. 6x + y < 3 ⇒ y < -6x + 3
NoB. -6x + y < 3 ⇒ y < 6x + 3
NoC. 6x - y < - 3 ⇒ y > 6x + 3

Step-by-step explanation:
If a sweatshirt is on sale for 35% and now costs $52,
what was the original price?
Answers
This is because you convert 35% to 1.35. Then, you multiply 52 by 1.35. That’ll give you 70.2.
Answer:
The original price of the sweatshirt is $80.
Step-by-step explanation:
If a product is on sale for a 35% discount, then it is 65% of the original price ( because 100 - 35 = 65)
So set up a proportion,
((part)/(whole)) = ((x)/(100))
In the given information, we know that the part (the amount paid) is 52$, what we need to find is the whole. To make solving the problem easier, let's call the whole x.
((52)/(x)) = ((65)/(100))
Simplify,
52/x = 13/20
Cross multiply,
1040 = 13x
Inverse operations,
1040 = 13x
/13 /13
80 = x
So the original price of the sweatshirt is $80.

For the equation 6 - m = 3, how many solutions are there for m?

Answers
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.

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
Step-by-step explanation: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 .
A recipe requires 7/8 stick of butter for each 1 1/4 cups of flour. Find the unit rate of sticks of butter to cups of flour.
Answers
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
How do you write 199.4% as a decimal?
Answers
Answer:
1.994
Step-by-step explanation:
"Percent" means "per 100" or "over 100". To convert 199.4% to a decimal rewrite 199.4 percent in terms of per 100 or over 100.
199.4% = 199.4 over 100 or,
199.4%=199.4100
199.4 over 100 is the same as 199.4 divided by 100. Completing the division we get:
199.4 ÷ 100 = 1.994
Therefore, we have shown that
199.4% = 1.994
Simplified Conversion:
Remove the percent sign % and divide by 100.
199.4 ÷ 100 = 1.994
Shortcut Conversion:
Move the decimal point 2 places to the left and remove the percent sign %
199.4% becomes 1.994
Answer:
1.99400

write an inequality to represent the product of x and 7 is at least 15
Answers
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]

I need to Write an explanation of how find the slope of a line given points A (1,5) B (-7,8) can someone help me please!
Answers
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.
