Based on the sample space, the probability of P(32) is 1/90
What is probability?The probability of an event is the chance or the likelihood that the event would occur.
Note that the chance or the likelihood is represented as a numerical value
How to determine the probability?The sample space is given as
Space = two-digit numbers
There are 90 two-digit numbers
So, the sample size is
Size = 90
There is only one two-digit number with the value 32
So, we have
n(32) = 1
The probability of selecting 32 is
P(32) = n(32)/Size
So, we have
P(32) = 1/90
Hence, the probability of P(32) is 1/90

A chemist is heating water so it can dissolve a larger amount of sodium chloride. The water's temperature increases 7°C each minute from an initial temperature of 21°C. How long will it take for the water to reach 49°C?
If water's temperature increases 7°C each minute from an initial temperature of 21°C. Then the time taken by the water to reach 49 degree Celsius is 4 minutes.
What is temperature?Temperature defines the atmosphere hotness. And it is expressed in different scales as well as in different parameters like Celsius etc. It is measured through the device known as thermometer.
According to the question, larger amount of sodium chloride is dissolved in the heating water. And the given data states that the water temperature increases 7 degree Celsius every minute.
Initial temperature of water is 21 degree Celsius.
Let us assume, water reaches at 49° C after 'x' minutes.
As per question, every minute temperature increases as 7°C. So, the expression can be written as: (21 + 7x)°C
⇒ 21 + 7x = 49
⇒x = 4 minutes
Hence, the time taken to reach 49° C is 4 minutes.

The coordinate of the resulting point J' is (-4, -4).
What is Coordinates?
A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the Coordinates.
The point is given as;
⇒ J (4, -4)
Now, The rule of the reflection of a point across the y-axis is equal to
(x, y) ⇒ (-x, y)

mai bought some party supplies from an online store.the shop charges a 7.95 shipping fee or 6.25%of the total purchase.whichever is greater.suppose Mai's total purchase is 128.how much shipping will she pay?
The required amount of shipping paid by Mai is 8.
What is percent?In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".
Now it is given that,
Amount of shipping fee = 7.95
percentage of shipping fee = 6.25% of the total purchase
Total amount purchased = 128
Thus, amount of shipping for this purchase is given as,
Amount of shipping = 6.25% of 128
Solving,
Amount of shipping = 0.0625*128 = 8
Since the shop charges shipping fees of whichever is greater
and 7.95 < 8
Thus, amount of shipping paid by Mai = 8
Thus, the required amount of shipping paid by Mai is 8.

Hello There!
The answer you are looking for is **8.25**.
Explanation:
If you do 8.25*12, you will get 99.
```Fact checking:
8.25*2= 16.50
8.25*4= 33.00
8.25*6= 49.50

1: Recycling Center A processes aluminum faster; Recycling Center B’s rate is about 12 pounds per hour.
2: Recycling Center A processes aluminum faster; Recycling Center B’s rate is about 24 pounds per hour.
3: Recycling Center B processes aluminum faster; its rate is about 120 pounds per hour.
4: Recycling Center B processes aluminum faster; its rate is about 240 pounds per hour.
We need to know about unitary method to solve the given question. Option () is correct, Recycling Center A processes aluminium faster; Recycling Center B's rate is about 24 pounds per hour.
Unitary method is a method to find out the value for a single quantity and then derive the value for the asked quantity. Here is this question we know Center A processes aluminium at a rate of 100 pounds per hour and center B processes 2 tons per week, we need to know who processes aluminium faster. To find the answer we need to first find how much aluminium center B processes per hour, to find that we need to use unitary method.
1 ton=2000 pounds
so, 2tons=2x2000=4000 pounds
Thus Center B processes 4000 pounds per week
A day has 24 hours, a week has 7 days, we know that the centers operate all day every day so number of hours in a week is
7x24=168 hours
Center B processes 4000 pounds in 168 hours
Center B processes 4000/168 pounds in one hour
Center B processes about 24 pounds in one hour
Therefore, we can see that Center A processes aluminium faster and Center B's rate is about 24 pounds per hour, thus option (2) is right.

a. Find and interpret C(1).
The value at intercept C(1) is 95.68 pounds
The estimated per capita consumption in the year 2010 will be 115.6 pounds
Part a:
Per capita consumption of all the poultry in a country is given by the function C(x) = 2.49x + 93.19
Finding intercept C(1):
For C(1) the value of x will be 1
C(1) = 2.49(1) + 93.19
C(1) = 95.68
Hence, the value at intercept C(1) is 95.68 pounds
Part b:
Finding the per capita consumption in the year 2010:
where x will be 9, as the time period from 2001 to 2010 is 9 years
C(2010) = 2.49(9) +93.19
= 22.41 + 93.19
