Emily and her children went into a grocery store and she bought $20.80 worth of bananas and peaches. Each banana costs $0.80 and
-BARSIC- [3]

b + p = 14 and 0.80 b + 2 p = 20.80 are the system of equations.

Step-by-step explanation:

Step 1 :

Let b be the number of bananas

Let p be the number of peaches  

Given that the total of bananas and peaches that Emily bought  = 14

Hence we have,

b + p = 14

Step 2 :

Cost of one banana =  $0.80

Cost of one peach = $2

Cost of all the bananas and peaches Emily bought = $20.80

So sum of b bananas costing $0.80 and sum of p peaches costing $2 each is $20.80

Hence we have

0.80 b +2 p = 20.80

Solving for the above 2 equations we can get the value for b and p which will give the number of bananas and peaches bought

Step 3 :

Answer :

The system of equations that could be used to find the number of the bananas and the number of the peaches that Emily bought is given by

b + p = 14

0.80 b +2 p = 20.80

Tom is throwing darts at a target. In his last 30 throws, Tom has hit the target 20 times. You want to know the estimated probab
Musya8 [376]

Each scenario can be used to simulate probability, and there are 3 correct scenarios and 2 incorrect scenarios in the list of options

<h3>How to categorize the simulations?</h3>

From the question, we have the following parameters:

  • Number of throws = 30
  • Number of hits = 20

This means that the probability of hit is:

P(Hit) = 20/30

Simplify

P(Hit) = 2/3

Using the complement rule,

P(Miss) = 1/3

The above means that the simulation that represents the situation must have the following parameters:

  • P(Success) = 2/3
  • P(Failure) = 1/3
  • Number of experiments = 3

Using the above highlights, the correct scenarios are:

  • Rolling a die three times with numbers 1 to 4 representing a hit
  • Spinner a spinner of 3 equal sections three times with two sections representing hit
  • Spinner a spinner of 6 equal sections three times with four sections representing hit

Suzy has a collection of quarters and dimes. Together she has 44 coins worth $6.95. How many quarters and how many dimes does Su
OverLord2011 [107]
X = quarters
y = dimes

0.25x + 0.10y = 6.95 or 25x + 10y = 695
x + y = 44

25x + 10y = 695
25 (x + y = 44)

25x + 10y = 695

25x + 25y = 1,100

-15y = -405
y = 27 dimes
and 17 quarters
