ruslelena [56]

Answer:

P = 4w + 8

Step-by-step explanation:

<em>Jose is creating a map in the shape of a rectangle whose length is 4 inches longer than its width. Let w stand for the width of the map in inches. Write an equation gives the perimeter of the map in terms of w?</em>

Perimeter of the rectangle = 2(L +w)

L is the length of the rectangle

w is the width

If the length is 4 inches longer than its width, then;

l = w + 4

Substitute into the expression;

P = 2 (L+w)

P = 2(w+4+w)

P = 2 (2w+4)

P = 4w + 8

Hence the perimeter of the map in terms of w is P = 4w + 8

Colossal canyon was formed in the shape of a parabola.The graph below shows the shape of the canyon.What interval is the functio
Roman55 [17]

Answer:

The function increasing ⇒ 3 ≤ x ≤ 6 answer C

Step-by-step explanation:

∵ The vertex of the parabola is (3 , -6)

∴ The minimum value = -6 at x = 3

∵ The left part of the parabola is decreasing because the value of y decreased from 3 to -6 when 0 ≤ x ≤ 3

∵ The right part of the parabola is increasing because the value of y  increased from -6 to 3 when 3 ≤ x ≤ 6

∴ The function is increasing at interval  3 ≤ x ≤ 6

Three players enter a room and a red or blue hat is placed on each person's head. The color of each hat is determined by a coin
Drupady [299]

Answer:

If you take into account all probabilities, and work on a strategy, rather than individual guesses, you can increase the probability.

 

Here are the possible outcomes:

 

BBB

BBR

BRB

BRR

RBB

RBR

RRB

RRR

 

If you use the strategy:

If a person sees a blue and a red, they pass;

If a person sees a blue and a blue, they guess red;

If a person sees a red and a red, they guess blue;

The probability comes out like this:

 

 

(B=blue, R=red, P=pass)

 

actual   guess   correct?

BBB RRR no

BBR PPR yes

BRB PRP yes

BRR BPP yes

RBB RPP yes

RBR PBP yes

RRB PPB yes

RRR BBB no

 

As you can see, this is a 6/8, or 75% chance of being correct.
