A dozen muffins costs $5. Large bottles
notka56 [123]

Answer: Option D) 3 x 5 + 4 x 2

Step-by-step explanation:

- Since a dozen muffins costs $5.

Buying 3 dozen muffins means (3 x $5)

- Since Large bottles of juice cost $2.

The cost of 4 large bottles of juice is (4 x $2)

Hence, the total cost is (3 x $5) + (4 x $2)

= $15 + $8

= $23

Now, you'll notice that "3 x 5 + 4 x 2" gives 23.

Thus, it is the only expression that could be used to find the total cost.

An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in California. Suppose that
sergiy2304 [10]

Answer:

(22.0297, 23.3703)

Step-by-step explanation:

Given that an economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in California.

Let X be per capita income (in thousands of dollars) for a major city in California.

Mean = 22.7

n = 183

Population std dev = 6.3

Since population std dev is known we can use Z critical value.

Std error = \frac{6.3}{\sqrt{183} } \\=0.4657

Z critical =1.44

Marginof error = ±1.44*0.4657=0.6706

Confidence interval 85%

=(22.7-0.6703, 22.7+0.6703)\\= (22.0297, 23.3703)
