Answer:
3 to 4
Step-by-step explanation:
Here, we want to know the ratio of blueberries to strawberries
To know this, we simply will compare the fractions of both
That will be;1/2 to 2/3
Multiply through by 6
3 to 4
60 square feet for 287 = 287/60 = 4.78 per square foot
so ur equation would be : y = 4.78x + 80....where x is the number of square feet and y is the total cost
Answer:
The expected number of keys she will try before she opens the door is 4.5.
Step-by-step explanation:
A woman has eight keys on a key ring, one of which fits the door she wants to unlock.
Each of them is equally as likely to be the one to work, which means that this situation is represented by an uniform distribution with lower bound 
and upper bound 
.
Find the expected number of keys she will try before she opens the door.
The expected value of the uniform distribution is given by:
Considering 
, as is the case in this exercise:
The expected number of keys she will try before she opens the door is 4.5.
Answer:
In Step 1: option D is correct
And in step 2: option A is correct.
Step-by-step explanation:
We have been given the graph
The figure in fourth quadrant after rotating 90 degrees counterclockwise about the origin will shift in first quadrant.
And after translating 4 units left will give the figure shown in second quadrant.
Therefore, In Step 1: option D is correct
And in step 2: option a is correct.
Answer:
7,744 (96.8% of population at the beginning of the year)
Step-by-step explanation:
Population of the city at the beginning of the year = 8000people
Yearly percentage decrease = 3.2%
This means at the end of the first year the population reduces by 3.2% which gives 3.2%of 8000
= 3.2/100 × 8000
= 3.2 × 80
= 256
This shows that the population decreases by 256 at the end of first year.
To get the 1year percentage change in population, we will subtract the percentage decrease in Population from the initial population to give;
8000 - 256
= 7,744
7,744population remains after 1year wish is (100-3.2)% i.e 96.8% of the population at the beginning of the year.
