The standard deviation is 2.08.
What is Standard Deviation?A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
We have the data,
X : 0 1 2 5 10
P(X) : 0.4 0.2 0.2 0.1 0.1
CF : 0.4 0.6 0.8 0.9 1
Sum of fx = 2.5
Mean = 2.5
Deviation X = -2.1 -2.3 -2.1 -2 -1.5
X² = 4.41 5.29 4.41 4 2.25
fX² = 1.764 1.058 0.882 0.4 2.225
Now, standard deviation
= √4.329/1
= 2.08

5 + x = 3(x - 7) + 6
Answers
Answer:
x=10
Step-by-step explanation:
x+ 5= 3x - 21 +6
x+5 = 3x - 15
20= 2x
The reason for this is you distribute the 3 giving you 5+x=3x-21+6.
Then add the 6 to make 5+x=3x-15
Add 15 on both sides to make 20+x=3x
Subtract x on both sides to be 20=2x
Divide both sides by 2 to make 10=x

one card from a deck of cards is selected, it is replaced, and another card is chosen. what is the probability that the first card is a red card and the second card is a diamond card?
Answers
Answer:
the probability of a red card is 1/2 of 50% chance. The chance of a diamond card is 1/4 or 25% chance
Step-by-step explanation:
Answer as a fraction = 1/8
Answer in decimal form = 0.125
Answer as a percentage = 12.5%
==========================================
Explanation:
The probability of choosing a red card is 1/2 since half of the cards are red (the other half are black).
This card is selected and then put back into the deck. This means that the second selection will deal with the same number of total cards.
Since we have four suits, and one of those suits is diamonds, this means the probability of choosing a diamond card is 1/4.
We then multiply the fractions to get (1/2)*(1/4) = (1*1)/(2*4) = 1/8
The probability of getting a red card first, then a diamond card second, is 1/8
Use your calculator to find that 1/8 = 0.125 which converts to the percent form 12.5%
A group of friends wants to go to the amusement park. They have no more than $235 to spend on parking and admission. Parking is $7, and tickets cost $28.50 per person, including tax. Write and solve an inequality which can be used to determine pp, the number of people who can go to the amusement park.
Answers
The solution of the inequality for the number of people (p) who can go to the amusement park will be;
⇒ p < 8
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
They have no more than $235 to spend on parking and admission.
And, Parking is $7, and tickets cost $28.50 per person, including tax.
Now,
Let the number of people who can go to the amusement park = p
So, We can formulate;
⇒ 28.50p + 7 < 235
Solve for p as;
⇒ 28.50p < 235 - 7
⇒ 28.50p < 228
⇒ p < 228/28.50
⇒ p < 8
Thus, The solution of the inequality for the number of people (p) who can go to the amusement park is;
⇒ p < 8
