Answer:

48.6

Step-by-step explanation:

Given the equation for the line of best fit ; f(x) ≈ 1.8x − 5.4 ;

This equation is used to make prediction for any given value of x ; Here, we are to make prediction for when x = 30

f(x) ≈ 1.8x − 5.4 ; we substitute into the equation, x = 30

f(30) = 1.8(30) - 5.4

f(30) = 54 - 5.4 = 48.6

Prediction at x = 30 is 48.6

Answer:

22.3 minutes

Step-by-step explanation:

The computation of the travel time is as follows:

Given that

[tex]\mu[/tex] = 17

And, the standard deviation is 4.5

P(X≤C) = 0.88

P( x - [tex]\mu[/tex]) ÷ [tex]\sigma[/tex] ≤  (C - [tex]\mu[/tex])  ÷ [tex]\sigma[/tex]  = 0.88

(C - [tex]\mu[/tex])  ÷ [tex]\sigma[/tex]  = 1.175

c = [tex]\mu[/tex] +  1.175 × [tex]\sigma[/tex]

= 17 + 1.175 × 4.5

= 22.3 minutes

Hence, the travel time is 22.3 minutes

Answer:

0.654

Step-by-step explanation:

There are 12 sweets in a bag.

4 are lemon flavour.

4 are caramel flavour.

4 are orange flavour.

Jude takes at random 3 sweets at the same time.

Work out the probability that exactly 2 of the sweets are the same flavour.

Probability = Required outcome / Total possible outcomes

Required outcome = either exactly 2 of lemon or 2 of caramel or 2 of Orange

Required outcome = 3[4C2 * 8C1) = 3(6*8) = 144

Total possible outcomes = 12C3 = 220

P(exactly 2 are same flavor) = 144 / 220 = 0.654

Answer:

Step-by-step explanation:

The equation to represent the perimeter of given figure is 5m-14+2m-7+3/2 m+2+3m+8=58 and value of m is 6.

Given that, the perimeter of the bookend is 58 centimeters.

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.

Now, the perimeter is

5m-14+2m-7+3/2 m+2+3m+8=58

⇒ 10m+3/2 m-11=58

⇒ (20m+3m)/2=69

⇒ 23m=138

⇒ m=138/23

⇒ m=6

Therefore, the equation to represent the perimeter of given figure is 5m-14+2m-7+3/2 m+2+3m+8=58 and value of m is 6.

Answer:

  positive

Step-by-step explanation:

When considering the slope of a line, we usually choose "rise" and "run" so that "run" is positive, and "rise" measures the vertical change as one moves from left to right.

If we assume that "downhill" lines refers to lines that go from upper left to lower right (downhill to the right), then the rise is negative while the run is positive.

__

Additional comment

Here, we assume a line is considered to be "downhill" if it has negative slope. In the real world, "downhill" is the direction the ball rolls under the influence of gravity. That direction might be behind you, or to your left, instead of in front of you or to the right.

Definitions are important in math. "Downhill" is not a term that is widely used to describe lines, so we have to guess the intended meaning here.

Answer:

x = 9

Step-by-step explanation:

angle <1 and angle <2 is complementary and their sum is 90 degrees

3x + 5x + 18 = 90 add like terms

8x + 18 = 90 subtract 18 from both sides

8x = 72 divide both sides by 8

x = 9 to find the measure of angle <1 replace x with the value we found

1/5 of the students are 4th graders

Answer:

10.5

Step-by-step explanation:

built different

Triangle F E D is cut by line segment H G. Line segment H G goes from side F D to side E D. The length of E G is 6 and the length of F H is 8. Lines E F and G H are parallel.  5.5 is the the length of Line segment G D.

A triangle is a polygon that has three vertices on each of its three sides. The point shaped inside the triangle is equivalent to 180 degrees. It implies that the amount of the inside points of a triangle is equivalent to 180°. This is a polygon with the fewest sides.

To put it another way, a triangle is a two-dimensional figure with three sides and interior angles of 180 degrees. Six main types of triangles are distinguished by their angles and side lengths. Allow us to examine exhaustively about the six kinds of triangles. In light of the length of the sides, the triangle is arranged

EG / GD = FH / HD

6 / GD  = 8 / 2

GD = 22 / 4

GD  = 5.5

Therefore, 5.5 is the the length of Line segment G D.

Answer:

  A.  18

Step-by-step explanation:

The area of a trapezoid is given by the formula ...

  A = 1/2(b1 +b2)h

Here, the parallel bases have lengths 3 and 9. The height is 3, so the area is ...

  A = 1/2(3 +9)(3) = 18

The area of the trapezoid is 18 square units.
