Linn is making cookies. Each batch of cookies

Pachacha [2.7K]

Answer:

4 cups of sugar require 14 cups of sugar

Step-by-step explanation:

Given

$\frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar$

Required

Determine the cups of flour for 4 cups of sugar

First, we need to determine the unit rate for 1 cup of sugar.

This is done by multiplying both sides by 4

$4 * \frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar * 4$

$\frac{7}{2}\ cup\ flour = 1\ cup\ sugar$

Next, we determine cup of flour for 4 cups of sugar.

This is done by multiplying both sides by 4

$4 * \frac{7}{2}\ cup\ flour = 1\ cup\ sugar * 4$

$2 * 7\ cup\ flour = 4\ cup\ sugar$

$14\ cup\ flour = 4\ cup\ sugar$

<em>Hence;4 cups of sugar require 14 cups of sugar</em>

A bulb can either be on or off. A board contains 20 bulbs connected to a randomization circuit that lights up a random sequence

Step2247 [10]

The chance that any given bulb is on is equal to 1/2. The chance that all twenty bulbs are on at the same time is $(\frac{1}{2}) ^{20} = \frac{1^{20}}{2^{20}} = \frac{1}{1048576}$

pshichka [43]

Answer: {(MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)}

Step-by-step explanation:

Sample space is a set that contains all the possible outcomes for an event.

For salad:

Choices for extra toppings (mushrooms, olives) =2

Choices for meats (bacon, eggs) =2

Choices for dressings (vinaigrette, honey mustard.)= 2

By Fundamental counting principal .

The number of different salads can be made= (Choices for extra toppings) x (Choices for meats ) x (Choices for dressings)

= 2 x 2 x 2 = 8

All the possible outcomes = (MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)

Required Sample space would be : {(MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)}
