inessss [21]

Answer:

Option C (The expression 2.35c + 1.75m represents the money earned from selling c bags of cookies and m bags of muffins).

Step-by-step explanation:

It is given that a bag of cookies is priced at $2.35 and a bag of muffin is priced at $1.75. It is also given that the student sells c bags of cookies and m bags of muffins. The total revenue earned by the student by selling c bag of cookies = $2.35 * c bags = $2.35c and the total revenue earned by the student by selling m bag of muffins = $1.75 * m bags = $1.75m. Therefore, the total revenue earned by the student by selling both cookies and muffins = 2.35c + 1.75m. This expression (2.35c + 1.75m) represents the money earned from selling c bags of cookies and m bags of muffins. Therefore, C is the correct choice!!!

A variety of stores offer loyalty programs. Participating shoppers swipe a bar-coded tag at the register when checking out and r
dsp73

Answer:

t=\frac{130-120}{\frac{40}{\sqrt{80}}}=2.236    

Now we can find the degrees of freedom:

df=n-1=80-1=79  

Now we can calculate the p value with the alternative hypothesis using the following probability:

p_v =P(t_{(79)}>2.236)=0.0141  

Using a significance level of 0.01 or 1% we have enough evidence to FAIL to reject the null hypothesis and we can conclude that shoppers participating in the loyalty program NOT spent more on average than typical shopper at this significance level assumed

Step-by-step explanation:

Information given

\bar X=130 represent the sample mean

s=40 represent the sample standard deviation

n=80 sample size  

\mu_o =120 represent the value to verify

t would represent the statistic  

p_v represent the p value

System of hypothesis

We want to verify if  shoppers participating in the loyalty program spent more on average than typical shoppers (120) , the system of hypothesis would be:  

Null hypothesis:\mu \leq 120  

Alternative hypothesis:\mu > 120  

The statistic for this case is given by:

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}  (1)  

Replacing the info given we got:

t=\frac{130-120}{\frac{40}{\sqrt{80}}}=2.236    

Now we can find the degrees of freedom:

df=n-1=80-1=79  

Now we can calculate the p value with the alternative hypothesis using the following probability:

p_v =P(t_{(79)}>2.236)=0.0141  

Using a significance level of 0.01 or 1% we have enough evidence to FAIL to reject the null hypothesis and we can conclude that shoppers participating in the loyalty program NOT spent more on average than typical shopper at this significance level assumed

What is -2 1/2 + 1 1/3 in fraction form?
olga nikolaevna [1]

-2\frac{1}{2} +1\frac{1}{3}=\frac{-1}{6}

Solution:

Given expression is -2\frac{1}{2} +1\frac{1}{3}.

Let us first convert mixed fraction into improper fraction.

-2\frac{1}{2} +1\frac{1}{3}=\frac{(-2\times 2) +1}{2} +\frac{(1\times 3) + 1}{3}

              =\frac{-4 +1}{2} +\frac{3 + 1}{3}

              =\frac{-3}{2} +\frac{4}{3}

Take LCM for the denominators (LCM of 2, 3 = 6) and make the same.

              =\frac{-3\times3}{2\times3} +\frac{4\times2}{3\times2}

              =\frac{-9}{6} +\frac{8}{6}

              =\frac{-1}{6}

-2\frac{1}{2} +1\frac{1}{3}=\frac{-1}{6}

Hence the fraction form of -2\frac{1}{2} +1\frac{1}{3} is \frac{-1}{6}.

If point p is 9/11 of the distance from M to N, what ratio does point P partition the directed line segment from M to N into?
stepan [7]

The ratio the point P partition the directed line segment from M to N is 9:2

<u>Step-by-step explanation:</u>

Let the total distance between M and N be 'd'

Point P distance from M = (9/11) d

Point P distance from N = (1 - 9/11) d

= (2/11) d

The ratio of the distance = (9/11) d / (2/11) d

= 9/2

= 9:2

The ratio the point P partition the directed line segment from M to N is 9:2
