How do you find any unit price?

The unit price of an item is the cost per unit of the item. We divide the price of certain number of units of an item by the number of units to find the unit price of that item.

In a recent survey of 1,050 people, 42 said that their favorite color of car was red. What percent of the people surveyed liked red cars?

Answers

In order to calculate the percentage of surveyed people that liked red cars, we need to divide this amount of people by the total amount of people surveyed.

So we have:

[tex]p=\frac{42}{1050}=0.04=4\text{\%}[/tex]

Therefore the percent of the people surveyed that liked red cars is 4%.

Answers

Answer:

(-2, 13)(1, 10)

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

Given system

y = x² + 9 x + y = 11

Substitute the value of y into second equation

x + x² + 9 = 11x² + x - 2 = 0x² +2x - x - 2 = 0x(x + 2) - (x + 2) = 0(x + 2)(x - 1) = 0x + 2 = 0 and x - 1 = 0x = - 2 and x = 1

Find the value of y

x = -2y = 11 - (-2) = 13x = 1y = 11 - 1 = 10

Answer:

[tex](x,y)=\left(\; \boxed{-2,13} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]

[tex](x,y)=\left(\; \boxed{1,10} \; \right)\quad \textsf{(larger $x$-value)}[/tex]

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}\phantom{bbbb}y=x^2+9\\x+y=11\end{cases}[/tex]

To solve by the method of substitution, rearrange the second equation to make y the subject:

[tex]\implies y=11-x[/tex]

Substitute the found expression for y into the first equation and rearrange so that the equation equals zero:

[tex]\begin{aligned}y=11-x \implies 11-x&=x^2+9\\x^2+9&=11-x\\x^2+9+x&=11\\x^2+x-2&=0\end{aligned}[/tex]

Factor the quadratic:

[tex]\begin{aligned}x^2+x-2&=0\\x^2+2x-x-2&=0\\x(x+2)-1(x+2)&=0\\(x-1)(x+2)&=0\end{aligned}[/tex]

Apply the zero-product property and solve for x:

[tex]\implies x-1=0 \implies x=1[/tex]

[tex]\implies x+2=0 \implies x=-2[/tex]

Substitute the found values of x into the second equation and solve for y:

[tex]\begin{aligned}x=1 \implies 1+y&=11\\y&=11-1\\y&=10\end{aligned}[/tex]

[tex]\begin{aligned}x=-2 \implies -2+y&=11\\y&=11+2\\y&=13\end{aligned}[/tex]

Therefore, the solutions are:

[tex](x,y)=\left(\; \boxed{-2,13} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]

[tex](x,y)=\left(\; \boxed{1,10} \; \right)\quad \textsf{(larger $x$-value)}[/tex]

The linear regression equation is expressed as

y = 0.

If a line passes through (-4,3) and (6,2) what's the equation if an equation isn't possible say no

Answers

First, let's find the slope of the line that passes through the points (-4,3) and (6,2):

[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \Rightarrow m=\frac{2-3}{6-(-4)}=\frac{-1}{6+4}=-\frac{1}{10} \end{gathered}[/tex]

Now we can use the first point to get the equation of the line:

[tex]\begin{gathered} (x_1,y_1)=(-4,3) \\ y-y_1=m(x-x_1) \\ \Rightarrow y-3=-\frac{1}{10}(x-(-4))=-\frac{1}{10}(x+4)=-\frac{1}{10}x-\frac{4}{10}=-\frac{1}{10}x-\frac{2}{5} \\ \Rightarrow y=-\frac{1}{10}x-\frac{2}{5}+3=-\frac{1}{10}x-\frac{2}{5}+\frac{15}{5}=-\frac{1}{10}x+\frac{13}{5} \\ y=-\frac{1}{10}x+\frac{13}{5} \end{gathered}[/tex]

therefore, the equation of the line is y=-1/10x+13/5

A scientist was in a submarine below sea level, studying ocean life. Over the next ten minutes, she descended 21.4 feet. How many feet had she been below sea level, if she was 90.6 feet below sea level after she descended?

Answers

Step 1:

Let the height below sea level before she descends = h feet

The length she descended after 10 minutes = 21.4 feet

The height of the submarine after descended below the sea level = 90.6 feet

Step 2:

Height of the submarine before descended below the sea level

x = 90.6 - 21.4

x = 69.2 feet

Final answer

69.2 feet

what is the solution set of y equals x squared plus 2X + 7 + y equals x + 7

Answers

The given equations are

y = x^2 + 2x + 7

y = x + 7

We would substitute y = x + 7 into the first equation. It becomes

x + 7 = x^2 + 2x + 7

Collecting like terms, it becomes

x^2 + 2x - x + 7 - 7 = 0

x^2 + x = 0

By factorising x, it becomes

x(x + 1) = 0

Thus,

x = 0 or x + 1 = 0

x = 0 or x = - 1

Substituting x = 0 into y = x + 7, it becomes

y = 0 + 7

y = 7

Thus, one solution set is (0, 7)

Substituting x = - 1 into y = x + 7, it becomes

y = - 1 + 7

y = 6

Thus, another solution set is (- 1, 6)

Therefore, the solution sets are

{(0, 7), (- 1, 6)}

Answers

The estimate is 5 while the difference is 4.3

Here, we want to find the estimate the difference and also get the real difference between the two numbers

To get the estimate, we round up each of the numbers to the closest integer

When we talk of an integer, we mean the nearest whole number

Thus, 8.5 becomes 9

while 4.2 becomes 4

The estimated difference is thus 9-4 = 5

However, the actual difference is what we have when we actually make a direct subtraction

Thus, mathematically, we have this as 8.5 - 4.2 = 4.3
