Answers

Answer 1

The probability that a randomly selected Riverside High School student is in twelfth grade is 0.4 and it can be determined by using probability.

Given that,

The two-way table shows the estimated number of students who will enroll in three area high schools next year.

A 5-column table has 4 rows.

The first column has entries Mount Woodson High School, Valley High School, Riverside High School, Total number of students.

The second column is labeled Tenth grade with entries 110, 180, 160, 450.

The third column is labeled Eleventh grade with entries 120, 150, 140, 410.

The fourth column is labeled Twelfth grade with entries 80, 120, 200, 400.

The fifth column is labeled Total with entries 310, 450, 500, 1,260.

We have to determine,

What is the probability that a randomly selected Riverside High School student is in twelfth grade?

According to the question,

The first column has entries Mount Woodson High School, Valley High School, Riverside High School, Total number of students.

The number of randomly selected Riverside High School students is in twelfth grade = 200,

And Total number of students in Riverside High School is = 500

Therefore,

The probability that a randomly selected Riverside High School student is in twelfth grade is,

[tex]\rm P(12th \ grade \students ) = \dfrac{Number \ of \ students \ in \ 12th \ grade }{Total\ number \ of \ students}\\\\ P(12th \ grade \students ) = \dfrac{200}{500}\\\\ P(12th \ grade \students )= 0.4[/tex]

Hence, The required probability that a randomly selected Riverside High School student is in twelfth grade is 0.4.

7) Sarawong spent half of his weekly allowance on candy. To earn more money his parents let him wash the dog for $6.10. What is his weekly allowance if he ended with $11.40?

Answers

Answer:

$10.60

Step-by-step explanation:

Sarawong ends with $11.40, and we need to find his weekly allowance by working backward. First, we learn that he earned $6.10 of that total amount of money by washing the dog, so we can subtract the two values:

11.4 - 6.1 = 5.3

So, before washing the dog, Sarawong had $5.30. But he only received this after spending half of his weekly allowance, so $5.30 must be half of his weekly allowance. If we multiply $5.30 by 2, we should be able to find his weekly allownce.

5.3 × 2 = 10.6

Now, we can check our work. First, he spends half of his weekly allowance on candy. Half of 10.6 is 5.3, so he now has $5.30. Then, he earns $6.10 more by washing the dog. 5.3 + 6.1 = 11.4, which is the ending value. So, our work was correct! Hopefully that's helpful. :)

Graph the line that passes through the points (-1,7) and (-3,5) and determine
the equation of the line.

Answers

Answer:

y = x + 8

Step-by-step explanation:

find slope first:

m = 7-5 / -1-(-3)

m = 2 / 2

m = 1

now find the y-intercept using either ordered pair; plug 'y', 'x', and 'm' into

y = mx + b  to solve for 'b'

7 = 1(-1) + b

7 = -1 + b

8 = b

put 'm' and 'b' into slope-intercept equation of a line, y = mx + b to get:

y = x + 8

for #1:

the pattern is subtracting 1,2,3,4 each time it goes to the next number.

29-28=1

28-26=2

26-23=3

23-19=4

19-?=5

19-14=5

so answer would be 5

for #2:

the pattern goes red triangle, red square, blue triange, blue square, red triangle, etc.

so with it continuing on, it would be red square

for #3:

the pattern looks like they're multiplying by 3 each time:

3x3=9

9x3=27

27x3=81

81x3=?

?=243

HELP!! Select the values for the domain and range of the functions graphed below.

Answers

Answer:

Graph 1

Range = -9 =< f(x) =< 9

Graph 2

Domain = -1 =< x =< 5

Range = -1 =< f(x) =< 2

Explaination:

Domain means the inputed x values on the x-axis, so to make things simpler and to not write every individual x values. We write it with <, >, and =<. (you can see it as the 'width' of a graph).

Range means the output y values on the y-axis. It's like the 'height' of a graph. And also, to make things simpler and to not write every individual y values. We write it with <, >, and =< with f(x) too because f(x) = y.

Adam is planning a pool party to celebrate the last day of school. He wants to give out beach towels to his guests as party favors. Adam ordered 14 beach towels from Sunshine Party Supply. Since this was a bulk order, Sunshine Party Supply reduced the price of each towel by $3.25. Adam paid $105 in all. How much does Sunshine Party Supply normally charge for a beach towel?

Answers

Answer:

10.75

Step-by-step explanation:

first step is to find how much adam paid for each towel

so, the equation used will be x/y=c

where x is total cost, y is number of products bought, and c equals individual cost (with discount)

we end up with 105/14= 7.5$ per towel.

and to close out, we add the given discount of 3.25 to the discounted price of 7.5

which brings the usual price per towel to 10.25

Answer: Check out the diagram below for the filled out table

Equation is y = 1.5x

Box for row one = 330

Box for row two = 1000

Box for row three = 1.5

===========================================================

Explanation

x = amount of fish in grams (horizontal axis)y = number of calories (vertical axis)

The point (x,y) = (200,300) is on the blue diagonal line. It indicates that x = 200 grams of fish have y = 300 calories. Divide the two values to get the slope

slope = y/x = 300/200 = 1.5

This trick only works because the line is going through the origin. Otherwise, we'd have to use the slope formula.

The slope of 1.5 is the constant of proportionality. It tells us the equation is y = 1.5x. Whatever x is, multiply by 1.5 to get y.

So if x = 220, then y = 1.5x = 1.5*220 = 330

220 grams of fish have 330 calories. We'll write 330 in the box of the first row of the table.

-----------------

We can use this idea in reverse. If we know the calorie count (y), then we can divide by 1.5 to get the number of grams (x).

y = 1.5x

1500 = 1.5x

1.5x = 1500

x = 1500/(1.5)

x = 1000

Therefore, 1000 grams of fish have 1500 calories. We'll write 1000 in the box of the second row.

------------------

The third row of the table is going to follow the same steps as the first row.

y = 1.5x

y = 1.5*1

y = 1.5

One gram of fish produces 1.5 calories
