A survey of 800 students yielded the following information: 519 were seniors, 430 were commuters, and 300 of the seniors were commuters. How many of the 800 surveyed students were seniors or were commuters?

Answers

Answer 1

Answer:

The number is  [tex](S \ u \ C ) = 649[/tex]

Step-by-step explanation:

From the question we are told that  

      The sample size is  n =  800

       The number of seniors is  S  =  519

         The number of  commuters is  C =  430

         The number of of seniors that are commuters is  [tex](S\ n \ C )= 300[/tex]

Generally the number of 800 surveyed students who were seniors or were commuters is  mathematically evaluated as

     [tex](S \ u \ C ) = S + C - ( S \ n \ C )[/tex]

=>   [tex](S \ u \ C ) = 519 + 430 - 300[/tex]

=>   [tex](S \ u \ C ) = 649[/tex]

6.258 rounded to the nearest hundredth

Answers

Answer:6.26Hope this helps!!

Answer:

6.26

Step-by-step explanation:

Integer Part: 6

Fractional Part: 258

If the last digit in the fractional part of 6.258 is less than 5, then simply remove the last the digit of the fractional part.

If the last digit in the fractional part of 6.258 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit.

If the last digit in the fractional part of 6.258 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is less than 9, then add 1 to the first digit in fractional part and make the second digit in fractional part 0. Then remove the third digit.

If the last digit in the fractional part of 6.258 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is 9, then add 1 to the integer part and make the fractional part 00.

With 6.258, rule B applies and 6.258 rounded to the nearest hundredth is 2.26

horizontal distance of 10 feet and rice 3 feet. Find the length of the ramp.

Answers

Answer:

Step-by-step explanation:

Tye length of the ramp can be gotten using Pythagoras theorem.

Horizontal distance = 10ft.

Vertical distance = 3ft

Length of the ramp² = 10²+3²

Length of the ramp² = 100+9

Length of the ramp² = 109

L² = 109

L =√109

L = 10.44ft

Hence the length of the ramp is 10.4ft to the nearest tenth

Alaina is making a birdseed mix with 2 1/3 lb sunflower seeds, 5/6 lb cracked corn, and 1/6 lb peanuts. How much cracked corn does Alaina need to make 5 lb of birdseed mix? Show your work.

Answers

Answer:1.25

Step-by-step explanation:

If you add everything it makes 3 and 1/3 pounds you want 5

If you divide 5 by 3 and 1/3 it's 1.5

Then you just need to multiply 5/6 by 1.5

For making 5 lb birdseed mix  1 ¹/₄ lb cracked corn will be used.

What is proportion ?

A proportion is an equation based on the equality of two ratios.

Here it is given that :

Alaina is making a birdseed mix with 2 1/3 lb sunflower seeds, 5/6 lb cracked corn, and 1/6 lb peanuts.

adding everything to make birdseed mix = 2 1/3 + 5/6 + 1/6 =10/3 lb

Now,

for making 10/3 lb birdseed mix = 5/6 lb cracked corn is used

in other words :

for making 1 lb birdseed mix = (5/6) x (3/10) lb cracked corn is used

that is , for making 5 lb birdseed mix = (5/6) x (3/10) x 5 lb cracked corn will be used.

 = 15/12 = 5/4 = 1 ¹/₄ lb  cracked corn will be used.

Therefore, for making 5 lb birdseed mix 1 ¹/₄ lb cracked corn will be used.

Order the set of integers from least to greatest 5, -3, -12, 9

Answers

Answer:

-12, -3, 5, 9

Step-by-step explanation:

ok. So the numbers are 5, -3, -12, and 9.

In these numbers, there are 2 negatives. They are -12 and -3.

In negatives, the bigger the number is, the number is smaller.

So we first put

-12, -3 as our 2 first. Then the other ones are 5 and 9.

and you obviously know that 5 is less than 9. try it out. 9-5 =4 which is positive

So then you put 5, 9

And our full answer is

-12, -3, 5, 9

-12, -3, 5, 9 is the correct order from least to greatest.

Population of California in the year 1995 was 32 million. If the population grows at a rate of 2%, what will the population be in 2025?

Answers

Answer:

hi 51.2 is the answer

Step-by-step explanation:have a good day.

The population of California in the year 2025 is approximately 57.96 million.

To calculate the population of California in 2025, we need to use the population growth formula:

Population in the future = Population in the present * [tex](1 + Growth rate)^{Number of years}[/tex]

Given:

Population in 1995 = 32 million

Growth rate = 2% = 0.02 (in decimal form)

Number of years = 2025 - 1995 = 30 years

Now, let's calculate the population in 2025:

Population in 2025 = 32 million * (1 + 0.02)³⁰

Population in 2025 ≈ 32 million * (1.02)³⁰

Population in 2025 ≈ 32 million * 1.8114

Population in 2025 ≈ 57.9648 million

Therefore, the population of California in the year 2025 is approximately 57.96 million.
