Answer:
Step-by-step explanation:
Given parameters:
Number of white balls = 24
Number of black balls = 16
Unknown:
The probability that white ball is drawn at random = ?
Solution:
The probability of an event is the likelihood of such an event to occur. That an event will occur has a probability of 1, it will not occur have a probability of zero.
In this problem, the total number of outcomes of drawing any ball has sample space of (24 + 16)outcomes = 40outcomes.
Probability of an event = 
Pr(white balls) = 
=
After a special medicine is introduced into a petri dish full of bacteria, Every second, the number of harmful bacteria remaining in the body decays by a factor of 0.97
<h3>What is
bacteria?</h3>
Generally, a kind of unicellular bacteria that has characteristics with many disease-causing organisms, such as having a cell wall but lacking organelles and an organized nucleus.
In conclusion, When a certain medication is put into a petri dish that is full of bacteria, the amount of pathogenic bacteria that are still present in the body decreases by a factor of 0.97 every single second.

Answer: binomial
Step-by-step explanation:
Two different terms separated by a plus or minus term defines a binomial. You have a binomial.
1/2x is one of the terms.
the minus sign comes next
the 7 is the second term.
Answer:
Step-by-step explanation:
Find the area of the square - area of 4 sectors
We'll use the formula to find one sector area
where r is the radius of one sector and x is the angle in radians
Since each angle is in a square, the angle of the sectors is 90 degrees.
Convert degrees to radians
The radius of one sector is given by 70mm/2=35mm
One sector area:
Area of all 4 sectors:
Area of the square:
Hence, Area of square - 4 Sectors:
9514 1404 393
Answer:
reflection across the line y = x
Step-by-step explanation:
The orientation of the triangle has changed from CW to CCW (considering sides in order least-to-greatest). This means a reflection is involved.
In order for this to be a single transformation, we need to know the line or point of reflection.
Each point is reflected about the point that is the midpoint joining an image point and the corresponding preimage point. Here, the points of reflection of the vertices all lie on the line y = x. So we can say ...
the transform is reflection across the line y = x
