Step-by-step explanation:
At a local restaurant, 40% of the lunch customers order a hamburger, 70% of the lunch customers order French fries, and 30% of lunch customers order both a hamburger and French fries. If a lunch customer is randomly selected from this restaurant, what is the probability that the customer order fries if we know they ordered a hamburger?
0.40
0.40
0.43
0.75
0.30
Answer:
hola anyone got tacos
Step-by-step explanation:
The probability that a customer orders fries given that the customer orders hamburger is 0.75
To solve this, we make use of the following representations
A represents the event that a lunch customer orders a hamburgerB represents the event that a lunch customer orders a French friesSo, we have:
[tex]P(A) = 40\%[/tex]
[tex]P(B) = 70\%[/tex]
[tex]P(A\ n\ B) = 30\%[/tex]
The probability that a customer orders fries given that the customer orders hamburger is calculated as:
[tex]P(B | A) =\frac{P(A\ n B)}{P(A)}[/tex]
So, we have:
[tex]P(B | A) =\frac{30\%}{40\%}[/tex]
[tex]P(B | A) =0.75[/tex]
Hence, the probability that a customer orders fries given that the customer orders hamburger is 0.75

Given that a = 3 and b = -1, what is the value of 2a - b?
Answer:
the answer is 7.
Step-by-step explanation:
here's why......if u place the 3 where a is it will become multiplication so that would be 2 times 3 minus b now but if u place -1 the minus becomes addition so it will be 6+1 which is 7.
Answer:
The value of expression when a=3 and b=-1 is 7
Step-by-step explanation:
Given expression is:
2a - b
Also given that
a = 3
b = -1
In order to find the value of the expression, we have to put 3 in place of a and -1 in place of b in the expression
So putting the values
[tex]=2(3)-(-1)\\=6+1\\=7[/tex]
Hence,
The value of expression when a=3 and b=-1 is 7

Find the area of a isosceles triangle having the base x cm and one side y cm
Answer: xy/2 cm²
Step-by-step explanation:
An isosceles triangle is a triangle that has two sides out of the three sides to be equal. The area of an isosceles triangle is given as:
= 1/2 × base × height
where,
base = xcm
height = ycm
Therefore,
Area = 1/2 × x × y
Area = xy/2 cm²

there are four children in Jana's family. She is less than 11 years old and is the oldest. there's a two-years age difference to twins, riya and seta, who come next. yuvi who is older than 5 is 2 years younger than the twins. how old are each of the children?
Answer:
Jana=10, twins=8, yuvi=6
Step-by-step explanation:
it's the only possible answer,as we know yuvi is older than 5 so let's just say she is 6 then the twins are 2 years older=8 and we know that and is less then 11 so that would be 10

The teacher baked a batch of muffins there's are 16 muffin in a batch she ate 1/4 of the batch she baked two more batches how many muffins does she have now
Answer:
Step-by-step explanation:
she ate 1/4 of the batch = 16/4 = 4 muffins were left
she baked two more batches = 16* 2 = 32
4 + 32 = 36 muffins
or
no. of muffins in a batch: 16
no of muffins he ate = 1/4 of 16
= 4
no. of muffins left: 16 - 4= 12
his mother then baked 2 more batches= 16+16
=32
no. of muffins left = 32+12 = 44

Ashley just lit a new candle and then let it burn all the way down to nothing. Let LL represent the length of the candle remaining unburned, in inches, tt hours after candle was lit. A graph of LL is shown below. Write an equation for LL then state the slope of the graph and determine its interpretation in the context of the problem.OnLy answer, answers plz
The linear equation that represents the length of the candle will be L = - t + 7. And the slope will be - 1 inch per hour.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Ashley just lit a new candle and then let it burn all the way down to nothing.
Let L represent the length of the candle remaining unburned, in inches, t hours after the candle was lit.
The slope is calculated as,
m = (0 - 7) / (7 - 0)
m = - 1 inch per hour
Then the linear equation is given as,
L = - t + 7
The linear equation that represents the length of the candle will be L = - t + 7. And the slope will be - 1 inch per hour.

Step-by-step explanation:
Please help!! Will appreciate. If you don’t know/ unsure don’t answer please
Answer:
The correct answer is graph B.
Hope This Helps! Sorry for late answer!
Answer:
its A because because the slope of the y-intercept is on the possative base towards the iquantities which is to be a posative number, in that case the y-intercept adds a 1 to the x which would lead towards the negative side therefor your answer will be y < -x -2

Answer:
64
Step-by-step explanation:
If you do the work:
1) Start with the whole numbers
20 x 3 = 60
2) Move to multiplying fractions
20 x 1/5
2a) To do this, start by turning the whole number into a fraction
20 x 1
1 5
2b) Cross-multply
20 x 1 = 20
1 x 5 = 5
2c) Divide
20/5 = 4
3) Add products
60 + 4 = 64
Rudy has three recipes for fruit punch. Each recipe calls for a certain amount of pineapple juice.
Recipe 1 2 cups of pineapple juice for 5 cups of punch
Recipe 2 7.2 cups of pineapple juice for 20 cups of punch
Recipe 3 6.4 cups of pineapple juice for 16 cups of punch
Use the information in the table to complete the statements below.
______ have the same proportion of pineapple juice to punch. For these two recipes, the unit rate of pineapple juice to punch is ________
.
If Rudy used either of these two recipes to make 3 cups of punch, there would be
________ cups of pineapple juice in in the batch.
Answer: Recipes 1 and 3 have the same proportion.
The unit rate is 1 cup of pineapple juice for 2¹/₂ cups of punch
To make 3 cups of punch, there would be 1.2 cups of pineapple juice.
To make 30 cups of punch, there would be 12 cups of pineapple juice.
Step-by-step explanation:
To find proportions, divide the amounts
2/5 = 0.4 7.2/20 = 0.36 6.4/16 = 0.4
I added the 30 cup batch because it seems unlikely that anyone would want to make only 3 cups of punch.
What value(s) of x in the relation below would
create a set of ordered pairs that is not a function?
Justify your answer.
{(0, 5) (1, 5) (2, 6) (x, 7)}
3 Answers: x = 0, x = 1, or x = 2
==================================================
Explanation:
The relation
{(0, 5) (1, 5) (2, 6) (x, 7)}
has points with x coordinates of: 0, 1, 2, and x.
If we repeated any of the x values listed so far, then we will not have a function.
So if we had the points (0,5) and (0,7), then the input x = 0 leads to multiple outputs. A function is only possible when any input x leads to exactly one output y.
This means that if x = 0, 1, or 2, then we won't have a function.
Side note: The y values can repeat, but if they do, then we won't have a one-to-one function. In this case, y = 5 repeats, so this function is not one-to-one (assuming x is not 0, not 1, and not 2).

Enter your answer as a whole number or a fraction in simplest form in the box.
Answer:
0
Step-by-step explanation:
As evident by the graph, nowhere does the line have any sort of slope. So, the slope must be zero.

Answer:
The cost of the new item is $72
Step-by-step explanation:
You can solve this by first putting the percent into decimal form, this is done by taking 25 and dividing by 100. Giving you 0.25
Now multiply 0.25 by the original cost of the item which is 96.
If you think about 0.25 as 1/4, because 25 is 1/4 of 100.
You will get 24, this is how much money is taken off of the original price.
So some easy subtraction: 96-24=72.
Now you have the new cost of the item
