The summit of a mountain pass is 8,050 ft above sea level. the valley below is 12 and 1/2 ft below sea level. what is the vertic
Veseljchak [2.6K]

Answer:

Vertical distance between the valley and the summit = 8062.5 ft

Step-by-step explanation:

Distances above the sea level are denoted by positive notations and below the sea level by negative notation.

Summit of a mountain pass = 8050 (above the sea level)

Valley below the sea level = 12 and half ft = (-12.5) ft

Distance between the summit and the valley = 8050 - (-12.5)

                                                                           = 8050 + 12.5

                                                                           = 8062.5 ft

Therefore, Vertical distance = 8062.5 ft will be the answer.

In a survey, 205 people indicated they prefer cats, 160 indicated they prefer dots, and 40 indicated they don’t enjoy either pet
maw [93]

Answer: probability =  0.506

Step-by-step explanation:

The data we have is:

Total people: 205 + 160 + 40 = 405

prefer cats: 205

prefer dogs: 160

neither: 40

The probability that a person chosen at random prefers cats is equal to the number of people that prefer cats divided the total number of people:

p = 205/405 = 0.506

in percent form, this is 50.6%

The Blinking Rockets baseball team has had 127,034 visitors to their fan website. Rounded to the nearest ten thousand how many v
horsena [70]

Answer:

Visitors = 130000

Step-by-step explanation:

Given

Visitors = 127034

Required

Approximate to the nearest ten thousand

First, identify the digit at the ten thousand position

From the given numbers of visitors, the digit is 2.

So, the next digit (which is 7) will be approximated and added to 2.

7 > 5. So, 1 will be added to 2.

The number of visitors becomes:

Visitors = 130000

In a multiple regression analysis what would likely be the culprit of a dramatic increase in the P-value of one of the variables
makvit [3.9K]
This can happen if you add another independent variable to your regression model that is strongly correlated to some other variable already in the model.
This is called multicollinearity. 
If there is a high correlation between your independent variables can lead to problems.
<span>It can lead to increased variance of the coefficient estimates and make the estimates very sensitive to minor changes in the model.</span>

(HELP ASAP)
aleksley [76]

Answer: The true statement is,

'N is the mid point of JL'.

Step-by-step explanation:

Since, By the given diagram we get the following information,

M is mid point of KL because, KM=ML,

N is the mid point of JL Because, JN=NL

If we connect the points M and N then we get a line MN,

Which is called mid segment.

And, By the Mid point theorem,

MN\parallel KJ and MN= KJ/2 = 12.8/2=6.4 m

Therefore from the above information we can say that only second Option  is correct.
