Answer:

The answer to your question is distance = 24 mi

Step-by-step explanation:

Data

speed = 12 mph

time = 2 hours

distance = ?

Process

To solve this problem, use the speed formula. Speed is a variable that measures the distance travel by a body over time.

speed = distance / time

-Solve for distance

distance = speed x time

-Substitution

distance = 12 x 2

-Result

distance = 24 mi

Three machines A, B, and C produce 55%, 25% and 20% respectively. The percentages of defective output are 3.5%, 4.5% and 5.5%. I

pishuonlain [190]

We are given the following information concerning the three production machines;

$\begin{gathered} Of\text{ the total production;} \\ A=55\text{ \%}=0.55 \\ B=25\text{ \%}=0.25 \\ C=20\text{ \%}=0.20 \end{gathered}$

Also, we are given the percentage of defective output as follows;

$\begin{gathered} A=3.5\text{ \%}=0.035 \\ B=4.5\text{ \%}=0.045 \\ C=5.5\text{ \%}=0.055 \end{gathered}$

Therefore, if an item is selected randomly, the probability that the item is defective would be;

$\begin{gathered} P\lbrack defective\rbrack=(0.55\times0.035)+(0.25\times0.045)+(0.20\times0.055) \\ P\lbrack\text{defective\rbrack}=0.01925+0.01125+0.011 \\ P\lbrack\text{defective\rbrack}=0.0415 \end{gathered}$

ANSWER:

The probability that the item is defective would be 0.0415

Evergreen Wildlife Preserve has 110 animals, and 66 of them are birds of prey. What percent of the animals are birds of prey?

Korolek [52]

Answer:

60%

Step-by-step explanation:

let ,x% is birds of prey

total animals=110

birds of prey=66

then,

x%of 110=66

x/100×110=66

110x/100=66

1.1x=66

x=66/1.1

x=60%

I'm not sure if this is correct.

Help Please solve this picture

Drupady [299]

6y = (x - 4)² + 34/3

6x = (y - 4)² + 34/3

(y - 4)² = 6x - 34/3

y - 4 = √(6x - 34/3)

y = 4 +- √(6x - 34/3)

Answer:

$\boxed{\large\sf y = 3x - 5}$

Step-by-step explanation:

Here we are given a equation which is ,

$\longrightarrow y = 3x + 6$

We need to find out the equation of the line which is parallel to the given line and passes through the given point .

And as we know that the slope of two parallel lines are equal .

On comparing the given equation with slope intercept form (y = mx + c )of the line , we have ,

$\longrightarrow m = 3$

Therefore the slope of the parallel line will be ,

$\longrightarrow m_{||}= 3$

Now we can use the point slope form of the line which is ,

$\longrightarrow y - y_1 = m(x - x_1)$

Substitute ,

$\longrightarrow y - 7 = 3 ( x -4)\\\\\longrightarrow y -7 = 3x -12 \\\\\longrightarrow y = 3x -12+7\\\\\longrightarrow y = 3x -5$

This is the required answer .
