Determine the point estimate of the population mean for the confidence interval of (15, 32). Enter up to 1 decimal place. Point

netineya [11]

Answer:

The point estimate of the population mean for the confidence interval of (15,32) is 23.5

Step-by-step explanation:

We are given the following information in the question:

Confidence interval for population mean is (15, 32).

We have to find the point estimate for population mean.

Formula:

$\mu = \displaystyle\frac{\mu_1+\mu_2}{2} = \frac{15+32}{2} = 23.5$

The point estimate of the population mean for the confidence interval of (15, 32) is 23.5

Liza is driving to her sister's house 360 miles away. After 4 hours, Liza is 2 3 of the way there.

DochEvi [55]

Liza is driving to her sister's house 360 miles away. After 4 hours, Liza is 2/3 of the way there. How many more hours does Liza have to drive?

Answer:

Liza need to drive 2 more hours to reach her sister house

Solution:

Given that Liza is driving to her sister's house 360 miles away

So total distance = 360 miles

After 4 hours, Liza is 2/3 of the way there.

$\frac{2}{3} r d \text { of total distance }=\frac{2}{3} \times 360=240$

So Liza has covered 240 miles in 4 hours

Let us find the speed

The relation between distance and speed is given as:

$speed = \frac{distance}{time}$

$speed = \frac{240}{4} = 60$

Thus speed = 60 miles per hour

Assuming speed is same throughout the journey, let us calculate the time taken to complete remaining distance

Remaining distance = 360 - 240 = 120 miles

Now distance = 120 miles and speed = 60 miles per hour

$time taken = \frac{distance}{speed}\\\\time taken = \frac{120}{60} = 2$

Thus Liza need to drive 2 more hours to reach her sister house

Solve for x. Each figure is a trapezoid. # 18 has a midsegment. 13)

Vanyuwa [196]

Question 13

${12x+2}=\frac{18+34}{2}\\\\12x+2=26\\\\12x=24\\\\x=\boxed{2}$

Question 14

Base angles of an isosceles trapezoid are congruent, so:

$73x+1=74\\73x=73\\x=\boxed{1}$
