The highest point in Chicago is 735 feet above sea level. You can represent that numerically using .

Answers

Answer:

+735 feets

Step-by-step explanation:

Points or position above sea level are denoted with positive elevation values while points or positions below sea level are denoted by negative values. The sea level position itself could be viewed as a midpoint such as the position of 0 on a number line ; where distances to the right are positive and distances to the left are negative.

Hence, a point which is said to be 735 feets above sea level would have an equivalent numeric representation of +735 feets

Good luck with this brainliest would be appreciated

Answer: 42.50m + 37.75

Step-by-step explanation:

Susan Carver will purchase a home for ​$190000. She will use a down payment of ​18% and finance the remaining portion at ​4.2%, compounded monthly for 30 years

Answers

Answer:

$548053.69

Step-by-step explanation:

Cost of home = $190000

Down payment = 18%

Loan amount = (1 - 0.18) * 190000 = $155800

Rate, r = 4.2% = 0.042 ; compounded monthly for 30 years

Using the relation :

A = P(1 + r/n)^nt

n = number of compounding times per period = 12

A = 155800(1 + 0.042/12)^(12 * 30)

A = 155800(1.0035)^360

A = 155800 * 3.5176745

A = 548053.69

Final loan amount = $548053.69

Samples of size 60 are drawn from a large population known to have a mean of 78 and a standard deviation of 12. What proportion of these samples would we expect to have a mean greater than 80?
a
0.566
b
0.098
c
Almost none
d
0.434
e
0.901

Answers

Answer: 0.098

Step-by-step explanation: First you’ll need to find the sample distribution mean and standard deviation (which is 78 and 1.55). Then you plug it into calculator using normal approximation cause n is large: normalcdf(80,100,78,1.55)

As, 0.098 proportion of these samples would, we expect to have a mean greater than 80. Thus, option (C) is correct.

What is the population?

As the population is defined, as  a group of groupings with a common characteristic. In data point, a population is the pool of individuals from which a statistical sample is drawn for a study. As we see, different countries have different populations.

As here the μ = 78, σ = 1.5492 and x = 80

We need to compute P(X >= 80). The corresponding z-value is calculated using Central Limit Theorem

z = (x - μ)/σ

z = (80 - 78)/1.5492 = 1.29

Therefore,

P(X >= 80) = P(z <= (80 - 78)/1.5492)

= P(z >= 1.29)

= 1 - 0.902 = 0.098

Therefore, The right option (B) is correct

Jim rides the bus to and from school each day. A one-way trip is 8.12 kilometers. How many kilometers does he travel in 3 days?

Answers

Answer:

48.72 km in 3 days.

Step-by-step explanation:

Given that,

A one-way trip is 8.12 kilometers.

We need to find the distance he travel in 3 days.

The distance traveled by Jim in one day to the bus and from school = 2(8.12) =  16.24 km

Distance traveled in 3 days = 3(16.24)

= 48.72 km

Hence, he will cover 48.72 km in 3 days.

25+81=[tex]c^{2}[/tex]

10.29563014 = c

Rounded to the nearest hundredth, 10.30
