fiasKO [112]3 years ago
8 0

Answer:

10

Step-by-step explanation:

let a = amount of apple

let g = amount of grapefruit

14a+25g=340

a+g=2a-2

-a     -a

g=a-2

plug this into your first equation

14a+25(a-2)=340

14a+25a-50=340

              +50  +50

39a=390

a=10

you have 10 apples

Anastaziya [24]

Answer:

The sampling technique used is convenience sampling.

Step-by-step explanation:

Convenience sampling technique is a method of non-probability sampling that is done using the most easiest sample or the most convenient sample.

For instance, sampling the people of our neighborhood, or school or company, etc.

This type of sampling is known as non-probability sampling because each individual\participant does not have a specific probability of selection. Whereas in case of probability sampling each participant has an equal probability of being selected.

A jazz concert brought in $119000 on the sale of tickets. If the tickets sold for and each, how many of each type of ticket were
Readme [11.4K]

Answer:

6850 & 650

Step-by-step explanation:

The question is partly incomplete as it didn't state the cost of ticket sold. Also, it didn't state the total number of tickets sold. But, assuming that the tickets sold were $15 and $25 tickets, and the total number of tickets sold was 7500, then we say that

Let x = the number of $15 tickets sold

Let y = the number of $25 tickets sold

x + y = 7500 y = 7500 - x

15x + 25y = 119000

15x + 25(7500-x) = 119000

15x + 187500 - 25x = 119000

-10x = -68500

x = 68500 / 10

x = 6850 tickets at $15 each

Remember from the first calculation, we said x + y = 7500, then

y = 7500 - 6850

y = 650 tickets at $25 each

All you have to do is substitute the values I assumed for your given value. Thanks
