Answers

Answer:

A? maybe i dont know dont quote me on that

Step-by-step explanation:

The Probability distribution is

Apples =1/5

Bananas = 3/10

Lemons = 1/15

Oranges = 4/15

Pears = 1/6

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Total Fruits = 30

Now, the probability distribution for the 30 pieces of fruit is

Apples = 6/30

            = 1/5

Bananas = 9/30

               = 3/10

Lemons = 2/30

              = 1/15

Oranges = 8/30

               = 4/15

Pears = 5/30

          = 1/6

A car travels at an average speed of 52 miles per hour. How long does it take to travel 247 miles? 0 hours [minutes X ? Check Explanation 202 MCQ 00​

Answers

Answer:

It takes 4.75 hours to travel 247 miles.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

A car travels at an average speed of 52 miles per hour.

This means that in 1 hour, the car travels 52 miles. How many hours for it to travel 247 miles?

1 h - 52 m

x h - 247 m

Applying cross multiplication

[tex]52x = 247[/tex]

[tex]x = \frac{247}{52}[/tex]

[tex]x = 4.75[/tex]

It takes 4.75 hours to travel 247 miles.

if y varies directly with x and y is 10 when x is 5 then what is y when x is 2

Answers

Answer:

y is 4

Step-by-step explanation:

so the equation is y = kx ( k is the constant)

We've been given x as 5 & y as 10 so we can use these values to find the constant .

10 = k(5)

k = 2

so now , we can find y

y = 2 × 2

y = 4

An ancient Chinese candle clock tells the amount of time that has passed by the amount of wax that has been melted off the candle.

If two candles have completely melted and one candle has melted 4\ \text{in}4 in4, space, start text, i, n, end text, how many minutes have passed since the first candle was lit

Answers

Answer:

[tex]Time = 560\ mins[/tex]

Step-by-step explanation:

Given

[tex]Candles = 2[/tex] --- candles melted

[tex]Divisions = 12[/tex]

[tex]Time = 4\ hrs[/tex] --- time to melt

Required

The time since the first was lit

If 1 candle melts in 4 hours, 2 candles will melt in 8 hours.

i.e.

[tex]x = Candles * Time[/tex]

[tex]x = 2 * 4hrs[/tex]

[tex]x = 8hrs[/tex]

For the 3rd candle that has melted, 4 inches

First, calculate the fraction that melt

[tex]Fraction = \frac{Melt}{Division}[/tex]

[tex]Fraction = \frac{4}{12}[/tex]

[tex]Fraction = \frac{1}{3}[/tex]

The time to melt is:

[tex]y = Fraction * Time[/tex]

[tex]y= 4 * \frac{1}{3}[/tex]

[tex]y= \frac{4}{3}hrs[/tex]

So, the required time is:

[tex]Time = x + y[/tex]

[tex]Time = 8hrs + \frac{4}{3}hrs[/tex]

Convert to minutes

[tex]Time = 8*60mins + \frac{4}{3}*60mins[/tex]

[tex]Time = 480mins + 80mins[/tex]

[tex]Time = 560\ mins[/tex]

Determine the equation for a line that passes through the point M(-7, 3) and
perpendicular to 7x − 2y + 3 = 0. Show your complete work.

Answers

Answer:

y = 2x/7 + 5

Step-by-step explanation:

the first line is defined by

7x - 2y + 3 = 0

in the most common way to write this we need an equation like y = ...

so, we isolate the y-expression in the equation :

2y = 7x + 3

y = (7x + 3) / 2 = 7x/2 + 3/2

the factor of x is the slope of the line, which is expressed by the y/x ratio indicating how many units y will change, when x changes e.g. 1 unit.

7/2 means that y will change by 7 units for every change in x by 2 units.

the slope of a perpendicular line is inverse to the slope of the original line, which means x and y are simply trading places (original x / original y).

so, the perpendicular slope of 7/2 is 2/7 (when x changes by 7 units, then y changes by 2 units).

that means the equation for the perpendicular line is something like

y = 2x/7 + c

the c we determine by using the coordinates of the given point (x and y values).

3 = 2×(-7)/7 + c = 2×(-1) + c = -2 + c

c = 5

so, the complete equation of the perpendicular line is

y = 2x/7 + 5

A medical equipment industry manufactures x-ray machines. The unit cost C( the cost in dollars to make each x -ray machine) depends on the number of machines made. If x machines are made, then the unit cost is given by the function C(x)=0.2x^2-100x+31,146.what is the minimum unit cost.

Answers

Answer:

18,646

Step-by-step explanation:

>you can graph the equation on a calculator and see that the minimum is at the point (250, 18646) , so the minimum unit cost is 18,646

>you can use the first derivative to find the minimum

c'(x) = (0.2x²-100x+31,146)' = .4x -100

.4x-100= 0 , so x= 250

c(x=250) = 0.2(250)² -100*250 +31,146 =18,646

Step-by-step explanation:

I cut out the extra square-ish pieces of the sides and found

then I found the perimeter of the sides of the rectangular shape and the sides were both 18.4ft. so 2(18.4+8.2)= 53.2.
