Translate to an equation and solve the following: The difference of p and one-sixth is two-thirds.
Answer: 5/6
Step-by-step explanation:
p - 1/6 = 2/3
+1/6 +1/6
p = 5/6
Answer:
p = 5/6
Step-by-step explanation:
For this problem, simply take the words of the problem and convert them into an equation as such:
The difference of p and one-sixth implies --> p - 1/6
is two-thirds implies --> 2/3
So, our equation:
p - 1/6 = 2/3
Now simply solve for p, and combine the fractions.
p - 1/6 = 2/3
p - 1/6 + 1/6 = 2/3 + 1/6
p = 2/3 + 1/6
p = 4/6 + 1/6
p = 5/6

You are contacted by the top cookie-selling Girl Scout troop in the city. As part of their sales plan for next year’s cookie selling season, they need to know (with 99% confidence, or α = 0.01) if the types of cookies purchased by their customers depends on where the scouts sell them. Here is their confidential sales data from last year:
Answer:
The types of cookies purchased by the customers depends on where the scouts sell them.
Step-by-step explanation:
The data provided is:

Events
A Chi-square test for goodness of fit will be used to determine whether the types of cookies purchased by the customers depends on where the scouts sell them.
The hypothesis can be defined as:
H₀: The observed frequencies are same as the expected frequencies.
Hₐ: The observed frequencies are not same as the expected frequencies.
The test statistic is given as follows:
[tex]\chi^{2}=\sum\limits^{n}_{i=1}\frac{(O_{i}-E_{i})^{2}}{E_{i}}[/tex]
The formula to compute the expected frequency is:
[tex]E_{i}=\frac{i^{th}\ \text{Row Total}\times i^{th}\ \text{Column Total}}{N}[/tex]
Consider the Excel output for the expected frequency values.
The Chi-square test statistic value is:
[tex]\chi^{2}=\sum\limits^{n}_{i=1}\frac{(O_{i}-E_{i})^{2}}{E_{i}}=56.788[/tex]
The degrees of freedom is:
df = (r - 1)(c - 1)
= (3 - 1)(5 - 1)
= 2 × 4
= 8
The p-value is:
[tex]P(\chi^{2}_{8}>56.788)<0.00001[/tex]
*Use a Chi-square table.
The p-value of the test is very small.
The null hypothesis will be rejected at 1% level of significance.
Conclusion:
There is enough evidence to support the claim that the types of cookies purchased by the customers depends on where the scouts sell them.
How many ink cartridges can you buy with 168 if one cost 14 dollars ?
168 ÷ 14 =12
ink
...
.
...
Answer:
Let the cost the number of cartridges be x.
We have given that cost of one cartridge is 14 $/cartridge.
And we have 168 $ with us.
So, according to question we have an equation-
14x=168
x=168/14
x=12
Hence, we can buy 12 cartridges if we 168 $ and the cost of one cartridge is 14 $.
The four cases in which we can solve a triangle are ASA SSA SAS SSS.
1) In which of these cases can we use the Law of Sines to solve the triangle?
A) ASA.
B) SSA.
C) SAS
D) SSS
2) Which of the cases listed can lead to more than one solution (the ambiguous case)?
A) ASA
B) SSA
C) SAS
D) SSS
Answer:
1) ASA
2) SSA
Step-by-step explanation:
The sine rule is used when we have; ASA, AAS or SSA cases. However, SSA is an ambiguous case which occurs when there are two sides and a given angle opposite one of these given sides. The triangles resulting from a situation like this requires a much closer look in comparison to SSS, ASA, and AAS cases. SSA may result in one triangle, two triangles, or even no triangle at all.

Since you want to show how the respiratory illnesses increase over the last 15 years, then plot a graph that shows such increase year by year.
What is the scale factor?
Answer:
I think the scale factor is 2 because 12 divided by 6 is 2.
Determine the quantity needed to replace the question mark to make the scale balance The weight times the distance on both sides of the fulcrum (the triangle) must be the same to make the scale balance
6 kg
3m

600 cm
The quantity needed to replace the question mark to make the scale balance is ? grams
work please, I wanna understand how to do it. thank you:)
Answer:
3kg = 3000 gm
Step-by-step explanation:
we use this formula
m1x (distance of m1 )= m2 x( distance of m2)
* the distance far from the triangle*
m1 =6 kg
d1 = 3m
m2 = ê (kg )
d2 = 600 cm = 6 m
m1 d1 = m2 d2
6 x 3 = ê 6
ê = 3 kg
mass = 3kg = 3000 gram
#
To make the scale balance, the weight must be added is 3000g.
What is a balancing equation?"A balanced equation is an equation where both sides are equal to the same amount. The answer to the expression on the left side of the equals sign (=) should be equal to the value on the right side of the equals sign".
For the given situation,
From the diagram shown, the distance on both sides of the fulcrum (the triangle) must be the same to make the scale balance.
We know that
1 kg = 1000 g
1 m = 100 cm
Let the unknown quantity be 'x'
To write a balanced equation, units should be the same on both sides.
6 kg = 6000 g
3 m = 300 cm.
The equation is represented as
[tex]6000[/tex] × [tex]300 = x[/tex] × [tex]600[/tex]
⇒ [tex]x = \frac{(6000)(300)}{600}[/tex]
⇒ [tex]x=3000[/tex]
Hence we can conclude that to make the scale balance, the weight must be added is 3000g.

Which statement identifies how to show that j(x) = 11.6ex and k(x) = In (StartFraction x Over 11.6 EndFraction) are inverse functions? All that needs to be shown is that j(k(x)) equals x. All that needs to be shown is that j(k(x)) equals 1. It must be shown that both j(k(x)) and k(j(x)) equal x. It must be shown that both j(k(x)) and k(j(x)) equal 1.
Answer:
It must be shown that both j(k(x)) and k(j(x)) equal xStep-by-step explanation:
Given the function j(x) = 11.6[tex]e^x[/tex] and k(x) = [tex]ln \dfrac{x}{11.6}[/tex], to show that both equality functions are true, all we need to show is that both j(k(x)) and k(j(x)) equal x,
For j(k(x));
j(k(x)) = j[(ln x/11.6)]
j[(ln (x/11.6)] = 11.6e^{ln (x/11.6)}
j[(ln x/11.6)] = 11.6(x/11.6) (exponential function will cancel out the natural logarithm)
j[(ln x/11.6)] = 11.6 * x/11.6
j[(ln x/11.6)] = x
Hence j[k(x)] = x
Similarly for k[j(x)];
k[j(x)] = k[11.6e^x]
k[11.6e^x] = ln (11.6e^x/11.6)
k[11.6e^x] = ln(e^x)
exponential function will cancel out the natural logarithm leaving x
k[11.6e^x] = x
Hence k[j(x)] = x
From the calculations above, it can be seen that j[k(x)] = k[j(x)] = x, this shows that the functions j(x) = 11.6[tex]e^x[/tex] and k(x) = [tex]ln \dfrac{x}{11.6}[/tex] are inverse functions.
