Answer:
The probability that he will score 1 point is 85.56%
Step-by-step explanation:
Mat will make 2 shots, and he has to score 1.
So, we are looking for the probability of score in the first shot or in the second.
Both probabilities are 62%
P(1 or 2) = P(1) + P(2) - P(1 AND 2)
P(1 AND 2)= P(1) x P(2)= 0.62 x 0.62=0.3844
P(1 or 2) = 0.62 + 0.62 -0.3844
P(1 or 2) = 0.8556

Answer:
<h2>5 - y</h2>
Step-by-step explanation:
Given the statement "subtract y from 5", we are to express the statement mathematically. Expressing mathematically is as shown;
5 - y
Since we are removing the value of a variable y from 5, <u>the variable we are subtracting will come last in the expression</u>. For example say, we want to subtract 5 from 10, since we are taking out 5 from 10, the value of 5 will come last in the expression i.e 10 - 5 not 5 - 10.
According to the statement in question, we can see that we are to subtract y from 5, therefore <u>y will come last in our expression</u> and will be expressed as 5 - y
Answer: the number of item A that you sold is 11
the number of item B that you sold is 2
Step-by-step explanation:
Let x represent the number of item A that you sold.
Let y represent the number of item B that you sold.
The total number of item A and item B sold is 13. This means that
x + y = 13
The cost of item A is $8 and the
cost of item B is $4. The total amount if money made is $88. This means that
8x + 4y = 88 - - - - - - - - - -1
Substituting x = 13 - y into equation 1, it becomes
8(13 - y) + 4y = 88
104 - 8y = 88
8y = 104 - 88 = 16
y = 16/8 = 2
x = 13 - y = 13 - 2 = 11
Answer:
Each board is (4/25) meters long = 0.16 meters long
Step-by-step explanation:
The board is 4/5 meters long, and he needs to cut 5 equal pieces, so we need to divide 4/5 of a meter in 5 parts.
This mathematically becomes: 4/5 divided by 5 which by the definition of division of rational numbers, is the same as :
4/5 times the reciprocal of 5 = (4/5) * (1/5) = (4/25) = 0.16 meters each board
