Robert is using the following data samples to make a claim about the house values in his neighborhood:House Value A $250,000 B $275,000 C $300,000 D $267,000 E $250,000 Based on the data, should Robert use the mean or the median to make an inference about the house values in his neighborhood? He should use the mean because it is in the center of the data. He should use the median because it is in the center of the data. He should use the median because there is an outlier that affects the mean. He should use the mean because there are no outliers that affect the mean.

You are going to a friend's house to watch a movie. If you drive on Street C, the distance is 3 miles. You need to stop at the movie store on Street A. The store is 1 mile from your house. What is the distance you will drive on Street B from the movie store to your friend's house? (right triangle)

Answers

Answer:

√(10) miles

Step-by-step explanation:

In the figure, let P be yours house and Q be your's friend's house. Let R be the movie store.

Note that the distance from your house and to your house on Street C is 3 miles.

The distance from your house and to the move store on Street A is 1 mile.

Now, the distance from the move store to your friend's house is the hypotenuse of the right triangle ΔPQR.

The distance from the move store to your friend's house is RQ.

In the right triangle ΔPQR,

RQ^(2) =PQ^(2) +PR^(2)

= 3^(2) +1^(2)

= 10

RQ=√(10)

Hence, the distance from the move store to your friend's house is √(10) miles.

Answer:

2.83 miles

Write and equation in standard form for a line that is (a) parallel (b) perpendicular to the line with an equation of y= 3x - 5 that passes through the point (5,8)

Answers

Answer:

  (a) 3x -y = 7

  (b) x +3y = 29

Step-by-step explanation:

(a) The standard form of the given line is ...

  3x -y = 5

The parallel line will have a constant on the right that makes it go through (5, 8), so it will be ...

  3x -y = 3(5) -(8)

  3x -y = 7

__

(b) The perpendicular line will have coefficients for x and y swapped and one of them negated. Again, the constant is chosen to make it go through (5, 8).

  x + 3y = (5) +3(8)

  x + 3y = 29

Angle S is 90 degrees and angle T is 45 degrees. side ST is 3 ft. how long is side SU

Answers

ANSWER

|SU|=3ft

EXPLANATION

Triangle TSU is an isosceles right triangle.

Because one of the angles in the right triangle is 45°.

This means that the third angle is also 45°.

This implies that that |ST|=|SU|

The reason is that isosceles triangle has the base angles equal and the arms on these angles are equal.

Spring street middle school orders 9 calculators for every 12 students. How many calculators do you predict the school would order for 132 students?

Answers

About 99 calculators
They would need to order exactly 99 calculators because 132 divided by 12 is 11 then 11 • 9 = 99
