a scientist need to 6000 calories per day. Based on the percentage of total daily calories and the number of calories needed, how many biscuits, packages of pemmican, butter and coco does a person need each day?
Answers
EXPLANATION:
Given;
We are told that a scientist needs 6000 calories per day.
We are also given a table showing the percentage of daily calories he can get from three types of food.
These are;
[tex]\begin{gathered} Biscuits---40\% \\ pemmican---45\% \\ Butter\text{ }and\text{ }cocoa---15\% \end{gathered}[/tex]Required;
We are required to calculate how many of each type of food he would need to eat each day.
Step-by-step solution;
We shall solve this by first determining how many calories can be gotten from each type of food based on the percentage given. This is calculated below;
[tex]\begin{gathered} Biscuits: \\ 6000\times\frac{40}{100}=2400 \end{gathered}[/tex]This means if he gets 75 calories from one biscuit, then to get 2,400 calories he would have to eat;
[tex]\begin{gathered} 75cal=1b \\ 2400cal=\frac{2400}{75} \\ 2400cal=32 \end{gathered}[/tex]The scientist would have to eat 32 biscuits to get 2400 calories.
[tex]\begin{gathered} Pemmican: \\ 6000\times\frac{45}{100}=2700 \end{gathered}[/tex]This means if he gets 135 calories from one pack of dried meat, then to get 2700 calories he would have to consume;
[tex]\begin{gathered} 135cal=1pack \\ 2700cal=\frac{2700}{135} \\ 2700cal=20 \end{gathered}[/tex]Therefore, the scientist would have to eat 20 packs of pemmican to get 2700 calories
[tex]\begin{gathered} Butter\text{ }and\text{ }Cocoa: \\ 6000\times\frac{15}{100}=900 \end{gathered}[/tex]This means if he eats 1 package of Butter and cocoa he gets 225 calories. To get 900 calories he would have to eat;
[tex]\begin{gathered} 225cal=1pack \\ 900cal=\frac{900}{225} \\ 900cal=4 \end{gathered}[/tex]Therefore, the scientist would have to eat 4 packs of Butter and cocoa.
We now have the summary as follows;

A basketball player shooting from the foul line has a 40% chance of getting a basket. He takes five shots. Whether he scores on one shot is independent of what he does on another shot. What is the probability that he misses at most one basket (rounded off to three decimals)?
Answers
The probability that the basketball player misses at most one basket is 0.077 as it is a mutually exclusive event.
what are mutually exclusive events in probability?Two events are said to be mutually exclusive if they cannot occur at the same time or simultaneously. This implies they are disjoint events and the probability of both events occurring at the same time will be zero.
Let us represent the probability of the player getting a basket to be p(y) and that of not getting a basket to be p(x)
then p(y)=40%=40/100=2/5
p(x)=1-(2/5)=3/5
The probability the player misses at most one basket implies his highest miss is one out of the five shots he took
So, the probability that he missed the:
1st shot= (3/5)×(2/5)×(2/5)×(2/5)×(2/5)=48/3125
2nd shot= (2/5)×(3/5)×(2/5)×(2/5)×(2/5)=48/3125
3rd shot= (2/5)×(2/5)×(3/5)×(2/5)×(2/5)=48/3125
4th shot= (2/5)×(2/5)×(2/5)×(3/5)×(2/5)=48/3125
5th shot= (2/5)×(2/5)×(2/5)×(2/5)×(3/5)=48/3125
The probability that he misses at most one basket= (48/3125)+(48/3125)+(48/3125)+(48/3125)+(48/3125)+(48/3125)= 249/3125=0.0768.
Finally, from the workings the probability that the player misses at most one basket is 0.077 rounded up to three decimals

Crystal's favorite playlist has 80 rock songs, 40 jazz songs, 25 country songs, 30 hip hop songs, and 45 classical music songs. Which of thesestatements is true?
Answers
This problem tests the knowledge of the probability of a random event occuring: of playing a type of song from a variety of different song types
Thus, we have to compute the probability that each type of song is played.
To do this, we need to obtain the total number songs, as follows:
80 + 40 + 25 + 30 + 45 = 220
Thus, the probabilities are now easily computed as follows:
P(rock) = 80/220
P(jazz) = 40/220
P(country) = 25/220
P(hip hop) = 30/220
P(classical) = 45/220
Now:
Option 1 (the first statement in the options) claims that : P(rock) = 2 * P(hip hop)
However, 2 * P(hip hop)

According to the question,
We have the following information:
A rectangle has sides measuring (2x + 5) units and (3x + 7) units.
A) We know that following formula is used to find the area of rectangle:
Area = length*breadth
Area = (3x+7)(2x+5)
Area = [tex]6x^{2}[/tex] + 15x +14x + 35
Area = [tex]6x^{2}[/tex] +29x + 35 square units
B) The degree of an expression is the highest power of the expression. In this case, the highest power is 2. Hence, the degree of the expression obtained is 2.The expression can be classifies as a quadratic polynomial.
C) Part A demonstrates the closure property for the multiplication of polynomials because the expression within the brackets are polynomials and the result obtained is also a polynomial.
Hence, the area of the rectangle is [tex]6x^{2}[/tex] +29x + 35 square units and the degree of the obtained expression is 2.
