A survey of 780 was conducted while visiting Sonoma county on vacation. Each person was asked if they drank wine on their trip. 532 people responded "Yes".

What proportion of people did NOT drink wine in the survey? Round your answer to two decimal places.

Answer:

9514 1404 393

Answer:

 $67,200

Step-by-step explanation:

The amount if interest is given by the formula ...

I = Prt

where P is the amount invested, r is the annual rate, and t is the number of years. Here, we want to find P when r = 0.05 and t = 1/2 such that I = 1680.

 P = I/(rt) = $1680/(0.05·0.5) = $1680/0.025

 P = $67,200

The amount invested was $67,200.

Answer:

-1/5

Step-b-1/5y-step explanation:

The rule for a perpendicular slope of a line is -1/s

In this case, we find the slope of the line first.
5x - y = -7
-y = -5x - 7
y = 5x + 7

The slope is 5, so -1/(5) is the slope of the perpendicular line.

After 10 years students in both schools are same.

Algebra is a branch of mathematics that uses mathematical expressions to represent problems. To form a meaningful mathematical expression, variables such as x, y, and z are combined with mathematical operations such as addition, subtraction, multiplication, and division. It teaches you how to solve a problem by following a logical path. As a result, you will have a better understanding of how numbers function and interact in an equation. You will be able to do any type of math better if you have a better understanding of numbers.

There are two high schools in a small town.

High school A has currently 900 students and is projects to grow by 30 students each year

Similarly

High school B has currently 750 students and is projected to grow by 45 students each year.

To find the equation for each situation in terms of t years.

also in how many years t' the number of students in both high schools would be same?

Given

The initial strength of school A = 900

the increasing rate of students = 30 students per year

i.e students in 1 year = 30

students in t years = 30t

Total students of school A after 't' years = 900+ 30t

⇒ A = 600+ 65t

The initial strength of school B = 750

increasing rate of students = 45 per year

i.e. student in 1 year = 45

⇒ student in 't' years = 45t

Total students of school B in 't' years = 950 + 30t

=> B=950+30t

Now to find no. of years 't' when students in both schools are the same i.e. A =B

⇒ 900+ 30t = 750 + 45t

⇒ 45t-30t = 900-750

⇒ 15t = 150

⇒t= 150 /15

⇒t=10

Therefore after 10 years, students in both schools are the same.

Here, it is given that the equation of the line parallel to the given straight line is [tex]y=\frac{3}{2} x-6[/tex]  ----(1)

We know that the slope of parallel lines is equal.

So, the slope of (1) will be equal to the given line.

Writing (1) in the form of [tex]y=mx+c[/tex], we get

Slope, [tex]m=\frac{3}{2}[/tex]

Using the Point-Slope Equation of the line, we have

[tex]y-y_{1}=m(x- x_{1})[/tex]

Now, substituting the point (-6,5) in the place of [tex](x_{1}, y_{1})[/tex], we get

[tex]y-5=\frac{3}{2} (x- (-6))\\\implies 2(y-5)=3(x+6)\\\implies 2y-10=3x+18[/tex]

Answer:-5/1

Step-by-step explanation:

down 5 and over 1

to get the slope, find a spot on the graph and then go 1 to the right and read how much the graph went up or down.
on 5) you see it did neither, so m=0
when the graph goes up, m is positive, when it goes down, m is negative.
so on graph 1, you have 2 dots.
you go 2 right, and 4 down. when the dots are not 1 apart (counting going right)  then divide by the steps you went right.
4 divided by 2 is 2.
-> graph went down, slope for 1) is m = -2

graph 2) you go 2 right and 2 up, 2/2 = 1. you went up, so m is positive and m = 1 for this graph.

3) is undefined because it doesn't go anywhere when you go right, it's 100% vertical

4) m = -5 because you went 1 right and 5 down

5) you go 6 right between the dots and 4 down. m is negative because it went down, not up. so m = -(4/6)

If the motor shaft rotated at 900 rpm, the speed of the larger gear will be 100 rpm.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

it is given that, A 35-tooth gear on a motor shaft drives a larger gear having 63 teeth and the motor shaft rotated at 900 rpm.

The number of teeth on the smaller gear,n₂ = 35

The number of teeth on the larger gear,n₁ = 63

The gear ratio is obtained as,

n₁/n₂=63/35

n₁/n₂=9:5

If the motor shaft rotated at 900 rpm, The speed of the larger gear is,

The equation of the given straight line is y = 3x.

We are given a graph. The graph shows a straight line. Several points are marked on the line in the graph. The coordinates of two such points are (1, 3) and (2, 6). We need to find the equation of the straight line.

The equation of the straight line can be found using the two-point form of a line. The equation is solved below.

(y - y1) = [(y2 - y1)/(x2 - x1)]×(x - x1)

(y - 3) = [(6 - 3)/(2 - 1)]×(x - 1)

The solution when Kaitlyn has at least five purses using signs and number is N ≥ 5

Equations and inequalities are both mathematical sentences formed by relating two expressions to each other.

When two expressions are equal, we use the equal sign ( = ). But when we are trying to compare two values or expressions, we use the inequality signs like greater than (>), less than (<), greater than or equal to ( ≥ ) and less than or equal to (≤)  

Given that: Kaitlyn has at least five purses

In order to solve this problem with signs and number, you will make use of the inequality that explains the situation:

Let the number of purses be N

Kaitlyn having at least five purses means she has 5 purses or more. Using inequality, the number of purses is greater than or equal to 5. Thus:

The quantity of first brand is 102 gallons and quantity of second brand is 68 gallons

Given,

The first brand of antifreeze = 70% pure antifreeze

The second brand of antifreeze =  95% pure antifreeze

The quantity of mixture = 170 gallons contains 80% pure antifreeze

We have to find the quantity of each brand of antifreeze must be used;

Now,

The quantity of first brand = x gallons

The quantity of second brand = y gallons

Then,

x + y = 170

x = 170 - y ....(1)

70x / 100 + 95y / 100 = (80 × 170) / 100

70x + 95y = 13600

Now, putting the value of x from equation 1:

70 (170 - y) + 95y = 13600

11900 - 70y + 95y = 13600

11900 + 25y = 13600

25y = 13600 - 11900

25y = 1700

y = 1700/25

y = 68

Now, putting this value of y in equation 1:
