Answer:

B. 3.19b + 4.59m = 137.24

3.49b + 4.39m = $140.04

Step-by-step explanation:

A B

Bread $3.19 $3.49

Milk $4.59 $4.39

Sue paid $137.24 in supermarket A

Sue paid $140.04 in supermarket B

Let

Price of bread A=$3.19

Price of bread B=$3.49

Price of milk A=$4.59

Price of milk B=$4.39

Quantity of Bread=b

Quantity of Milk=m

Pb=price of bread

Pm=price of milk

Qb=Quantity of bread

Qm=Quantity of milk

For each supermarket

Supermarket A Equation

PbQb + PmQm =$137.24

3.19b+ 4.59m = 137.24

Supermarket B Equation

PbQb + PmQm=$140.04

3.49b + 4.39m = $140.04

Combining both equations

3.19b + 4.59m = 137.24

3.49b + 4.39m = $140.04

What happens to the function f(x)=x^4 when it becomes f'(x)=x^4+5
il63 [147K]

Answer: It will move up 5 spaces on the y-axis.

Step-by-step explanation: y=mx+b where b is the y-intercept (where it will be on the y-axis). In the 1st one it doesn’t have a b so there is no y-intercept so it will pass through point (0,0). In the 2nd one since your adding 5 it will now pass through point (0,5). Because it shifted up 5 on the y-axis.

In a study of the accuracy of fast food​ drive-through orders, one restaurant had 40 orders that were not accurate among 307 ord
klemol [59]

Answer:

We conclude that the rate of inaccurate orders is greater than ​10%.

Step-by-step explanation:

We are given that in a study of the accuracy of fast food​ drive-through orders, one restaurant had 40 orders that were not accurate among 307 orders observed.

Let p = <u><em>population proportion rate of inaccurate orders</em></u>

So, Null Hypothesis, H_0 : p \leq 10%     {means that the rate of inaccurate orders is less than or equal to ​10%}

Alternate Hypothesis, H_A : p > 10%      {means that the rate of inaccurate orders is greater than ​10%}

The test statistics that will be used here is <u>One-sample z-test</u> for proportions;

                          T.S.  =  \frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n} } }  ~ N(0,1)

where, \hat p = sample proportion of inaccurate orders = \frac{40}{307} = 0.13

           n = sample of orders = 307

So,<u><em> the test statistics</em></u> =  \frac{0.13-0.10}{\sqrt{\frac{0.10(1-0.10)}{307} } }  

                                    =  1.75

The value of z-test statistics is 1.75.

<u>Also, the P-value of the test statistics is given by;</u>

            P-value = P(Z > 1.75) = 1 - P(Z \leq 1.75)

                          = 1 - 0.95994 = <u>0.04006</u>

Now, at 0.05 level of significance, the z table gives a critical value of 1.645  for the right-tailed test.

Since the value of our test statistics is more than the critical value of z as 1.75 > 1.645, so <u><em>we have sufficient evidence to reject our null hypothesis</em></u> as it will fall in the rejection region.

Therefore, we conclude that the rate of inaccurate orders is greater than ​10%.

In this figure, the distance from A to B is 10 units. The distance from B to X is 10 units. What else is true? 
evablogger [386]
I believe it would be a to X is 20 units because A to B is 10 units so a to X would make sense if it was 20 units hope this helps!
