Explain 15 is not a prime factor
Answers
15 is not a prime factor as it is divided by 1,3,5 and 15.
Additional information:
Prime numbers are those numbers which can only be divided by itself .for instance:1,2,3,5,7 ,11,13 etc.
Composite number s are those numbers which can be also divided by other numbers,For instance: 4,6,8,10 etc

A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times. Using the results of the simulation, what is the experimental probability that the player does not hit the dartboard? Express your answer as a decimal.
Can someone please help me i am so confused.
Answers
Answer:
0.25
Step-by-step explanation:
If the person made it 105 out of 140 times, that can be written as a fraction: 105/140
Then, you just turn the fraction into a decimal by dividing the numerator by the denominator.
105 divided by 140 = 0.75
0.75 is the probability that it does hit the board, so we can subtract 0.1-0.75 to give us the probability that is doesn't hit the board. This would give us 0.25
Hope this helps
The experimental probability that the player does not hit the dartboard is,
⇒ 1 / 14
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times.
Hence, Number of not hit dartboard is,
⇒ 140 - 105
⇒ 35
Thus, The experimental probability that the player does not hit the dartboard is,
⇒ 35 / 140
⇒ 7 / 28
⇒ 1 / 14

Keith will run at most 26 miles this week. So far, he has run 14 miles. What are the possible numbers of additional miles he will run? Use t for the number of additional miles he will run. Write your answer as an inequality solved for t.
Answers
Answer:
\(t \leqslant 12\)
Step-by-step explanation:
We know that Keith has ran 14 miles already, and he's aiming to reach no more than 26 miles, this week.
So we can put:
\(14 + t \leqslant 26\)
Since, 14 is the number we know, t represents the number we have yet to find, and 26 is the product of this inequality. (We use the less-than-or-equal-to sign, because Keith is only aiming for 26 or less miles.)
Now we solve:
Subtract 14 on both sides to get
\(t \leqslant 12\)
So t is less-than-or-equal-to 12, meaning Keith has 12 or less miles to run in order to reach 26 miles.
Hope this helps :)

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.
