Consider the equation 14*10^0.5w=100 Solve the equation for w. Express the solution as a logarithm in base-10

Answers

Answer 1

Answer:

Step-by-step explanation:

14*10^0.5w=100

$14*10^(0.5w)=100$

Solve the equation for w

divide by 14 on both sides

$10^(0.5w)=(100)/(14)$

Convert exponential form into log form

base is 10 so we convert into log form

log (a)= x then a=10^x

$10^(0.5w)=(100)/(14)$

$0.5w = log((100)/(14) )\n0.5w = log((50)/(7) )\n\n$

divide both sides by 0.5

$0.5w = log((50)/(7) )\n\n\nw= 2 log((50)/(7) )$

Answer:

$w= 2 log((50)/(7) )$

Given that a 90% confidence interval for the mean height of all adult males in Idaho measured in inches was [62.532, 76.478]. Use this to answer all parts. What was the point estimate used to estimate the mean height of all adult males in Idaho?

Answers

The point estimate used to estimate the mean height of all adult males in Idaho was 69.505 inches.

Calculation of the estimation of the point

Since Given that a 90% confidence interval for the mean height of all adult males in Idaho measured in inches was [62.532, 76.478].

So, the estimation of the point is

$= (62.532 + 76.478) / 2$

= 69.505 inches

Answer:

The point estimate used to estimate the mean height of all adult males in Idaho was 69.505 inches.

Step-by-step explanation:

The point estimate is the halfway point of the confidence interval, that is, the lower bound added to the upper bound, and then this sum is divided by 2. So

Lower bound: 62.535

Upper bound: 76.478

Point estimate:

$P_(e) = (62.535 + 76.478)/(2) = 69.505$

The point estimate used to estimate the mean height of all adult males in Idaho was 69.505 inches.

Give a ballpark estimate of the number of seats in a typical major league ballpark

Answers

The smallest is 31,000; the largest is 56,000. A "typical" stadium might hold about 43,000 spectators.

Final answer:

A typical major league ballpark can seat anywhere from 30,000 to 50,000 spectators on average.

Explanation:

A typical major league ballpark has a capacity ranging between 30,000 to 50,000 seats on average. This ballpark estimate is based on the capacities of a multitude of major league stadiums throughout the United States.However, the exact number can vary greatly depending on the specific design and configuration of each ballpark. Some are designed to accommodate large crowds for popular events, while others are smaller for more intimate settings. It's also worth noting that the number of seats can be changed for different events, such as concerts or other sports. This estimate gives you a general idea of the capacity of a major league ballpark but keep in mind the numerous variables that can affect the final number.
