The chance of picking a almond cookie the first time:
you have 6 cookies, 3 of them are almond
So the chance of taking an almond cookie is
$\frac{3}{6} = \frac{1}{2}$
The second time there are 5 cookies left, 2 of them are almond cookies
The chance of taking an almond cookie is
$\frac{2}{5}$
To know the probability of picking two almond cookies in a row, multiply the changes:
$\frac{1}{2} \times \frac{2}{5} = \frac{1}{5}$
The chance of taking two almond cookies is 1/5

Geometry// question #8

MAVERICK [17]

Answer:

see explanation

Step-by-step explanation:

The translation rule

(x, y ) → (x + 3, y - 2 )

Means add 3 to the original x- coordinate and subtract 2 from the original y- coordinate, thus

A(- 4, 1 ) → A'(- 4 + 3, 1 - 2 ) → A'(- 1, - 1 )

B(1, 1 ) → B'(1 + 3, 1 - 2 ) → B'(4, - 1 )

C(1, - 2 ) → C'(1 + 3, - 2 - 2 ) → C'(4, - 4 )

D(- 4, - 2 ) → D'(- 4 + 3, - 2 - 2 ) → D'(- 1, - 4 )

Suzanne needs material for her school project. She buys 4.75 yards of material at $5.37 a yard. What is the total cost of the ma

vovangra [49]

The material costs 5.37 for 1 yard.

Multiply the cost of 1 yard by the number of yards bought:

5.37 per yard x 4.75 yards = $25.51 Total cost.

The answer would be D.

If f(x) and f⁻¹(x) are inverse functions of each other and f(x)=2x+5, what is f⁻¹(8)?

dexar [7]

Answer:

3/2.

Step-by-step explanation:

f(x)=2x+5 Finding the inverse:

y = 2x + 5

2x = y - 5

x = (y - 5)/2

So the inverse f-1(x) = (x - 5)/2

and f-1(8) = (8-5)/2

= 3/2.

PLEASE HELP WILL GIVE 15 POINTS

natka813 [3]

Answer:

Step-by-step explanation:

Hello, when you have an equation like y = ax+b you know that this is a line.

In this example, the function is defined in two different intervals.

For x < 1 this is the line y = 4 + x

and for x>=1 this is the line y = 4 - 2x

At the frontier, x= 1, we have 4+1=5 on one side and 4-2=2 on the other side, we we expect a "jump" in the graph.

Except that "jump"you just have to draw lines, so if you have two points you can draw them right.

For x<1, the line is passing by (-4,0) and (0,4)

And you have to stop for x<1 so the point (1,5) is not on the graph.

for x>=1 the points (1,2) and (2,0) are on the graph and we just have to draw the line.

I attached the graph.

Thanks
