The fruit store sells 10,000 apples....
it sells 1/2 apples per day......
what is half of 10,000? It’s 5,000
so, I think it’s 5,000.... I don’t know bc it does not tell how many days........
Answer:
10000 divided by 2 equals
5000 divided by 2 equals
2500 divided by 2 equals
1250 divided by 2 equals
625 which divided equals half apples

Every week a company provides fruit for its office employees. They can choose from among five kinds of fruit. What is the probability distribution for the 30 pieces of fruit, in the order listed? Fruit Apples Bananas Lemons Oranges Pears 6 9 2 8 5 Number of pleces Probability O A. 1, 1 3 1 4 1 5 10 15 15 6 ОВ. 1 I 4 2 5 10 3° 15' 15 c. bot , 1 OD. 1 1 1 4 2 • 15. 5. 15 15
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

Solving a word problem involving rates and time conversion
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
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
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. Each candle is divided into 121212 sections, marked 111 inch (\text{in})(in)(, start text, i, n, end text, )apart. It takes 444 hours (\text{hrs})(hrs)(, start text, h, r, s, end text, )for each candle to completely melt, after which a new candle is lit. 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
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.
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.
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

for the perimeter of the shape.
Step-by-step explanation:
I cut out the extra square-ish pieces of the sides and found
that both are 17.2 for their perimeter. so 17.2×2= 34.4
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.
so 53.2+34.4 = 87.6ft.

Answer:
60 cubic inches
Step-by-step explanation:
if its a triangle you have to divide it by 2 because its half of a square so its half of an answer so in this case you multiply 10 and 12 which gets you 120 divide that by 2 you get 60 and that's your answer.
