Given :

Emily sells erasers for $2 per package and pencils for $5 per package. she sells 220 total packages and earns $695.

To Find :

The number of packages of erasers and pencils that were sold .

Solution :

Let, number of erasers are x and pencils are y.

So, x + y = 220    ....1

Also, 2x + 5y = 695   ....2

Solving equation 1 and 2, we get :

2(220-y)+5y = 695\\\\440 - 2y + 5y = 695\\\\3y = 255\\\\y=85

x = 220 - 85 = 135

Therefore, the number of packages of erasers and pencils that were sold are 135 and 85 respectively.

Hence, this is the required solution.

The amount of time it takes Ariana to do a math problem is continuous and uniformly distributed between 38 seconds and 79 second
solniwko [45]

Answer:

29.27% probability that it takes Ariana between 58 and 70 seconds to do a math problem

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X between c and d, d being greater than c, is given by the following formula:

P(c \leq X \leq d) = \frac{d-c}{b-a}

Uniformly distributed between 38 seconds and 79 seconds.

This means that a = 38, b = 79

What is the probability that it takes Ariana between 58 and 70 seconds to do a math problem

c = 58, d = 70

P(58 \leq X \leq 70) = \frac{70 - 58}{79 - 38} = 0.2927

29.27% probability that it takes Ariana between 58 and 70 seconds to do a math problem
