Mila and samuel had an equal amount of money for shopping. Mila spent $42 and Samuel spent $36. After that, Mila had 1/2 of what Samuel has left. How much money Milla had initially?
Answer:
Mila had $48 initially
Step-by-step explanation:
Let the amount of money they had be x
Mila spent $42; what is left would be x-42
Samuel spent $36: what is left would be x-36
So, what Mila had left is half of what Samuel has; that would be;
x-42 = 1/2(x-36)
2(x-42) = x -36
2x-84 = x -36
2x - x = 84 -36
x = $48

Your classmate says that the solutions to the given inequality are x > -2. Look carefully at the work. Should your friend have reversed the inequality symbol? Explain. Then solve the inequality correctly.
Please don't send those annoying files, I'm not trying to get a virus on my laptop. Please, if you can, just write out the steps/answer(s).
Answer:
x < -2 (No, he shouldn't have reversed the inequality symbol).
Step-by-step explanation:
Given the algebraic expression;
19 - 2(1 - x) < 13
Opening up the bracket, we have;
19 + (-2*1) + (-2*-x) < 13
19 + (-2) + (2x) < 13
19 - 2 + 2x < 13
17 + 2x < 13
Rearranging the equation, we have;
2x < 13 - 17
2x < -4
Dividing both sides by 2, we have;
x < -2
Hence, your friend shouldn't have reversed the inequality symbol (sign).
Note: you should only flip the inequality symbol (sign) when you're dividing by a negative number such as -2.
For example, if we had re-arranged the equation as;
17 - 13 < -2x
4 < -2x
Dividing both sides by -2, we have;
4 > x

If Westville has 15,200 households, predict the number of households that will have exactly 3 computers? Please answer I need help
Answer:
1140 households
Step-by-step explanation:
The results of a computer survey of 80 households in Westville are shown in the table.
So from the table we can see that 6 households have 3 numbers of computers.
So the probability is [tex]$\frac{6}{80}$[/tex]
Therefore, the probability of number of houses from a total of 15,200 houses to have exactly three computers is = [tex]$\frac{6}{80} \times 15200$[/tex]
= 1140 houses

Answer:
x = 6
y = 6[tex]\sqrt{2}[/tex]
z = 12
Step-by-step explanation:
the ratio of sides in a 30-60-90° triangle is, respectively, 1 : [tex]\sqrt{3}[/tex] : 2
therefore, 'x' must have a measure of 6
which means the hypotenuse must have a measure of 12
other triangle is a 45-45-90° triangle whose sides are in a ratio of 1 to [tex]\sqrt{2}[/tex]
this means that 'y' must be 12/[tex]\sqrt{2}[/tex] which is 6[tex]\sqrt{2}[/tex]
'z' must be 6[tex]\sqrt{2}[/tex] · [tex]\sqrt{2}[/tex] = 12
The vertices of ΔJKL are J(–3, –2), K(1, 4), and L(4, 2). Which coordinate pairs are vertices of D5(ΔJKL)? Select all that apply.
Answer:
J' = (-15, -10)
K' = (5, 20)
L' = (20, 10)
Step-by-step explanation:
Given the coordinates J(–3, –2), K(1, 4), and L(4, 2)
D5(ΔJKL) means we need to dilate the coordinates by a constant of 5
To do that, we will multiply the coordinates by a value of 5
D5(ΔJKL)
J' = (5(–3), 5(–2)),
J' = (-15, -10)
K' = (5(1), 5(4))
K' = (5, 20)
L' = (5(4), 5(2))
L' = (20, 10)

A) The relative frequency of "like snowmobiles" and "like skateboards" is 76.2%. B) The relative frequency of "like snowmobiles" and "do not like skateboards" is 15.6%. C) The row conditional relative frequencies of "like snowmobiles" and "like skateboards" is 76.2%. D) The row conditional relative frequencies of "do not like snowmobiles" and "like skateboards" is 28.1%. E) The column conditional relative frequencies of "do not like skateboards" and "do not like snowmobiles" is 28.6%.
Answer:
a)45/125
b)25/125
c)80/125
d)45/125
e)10/35
Step-by-step explanation:
hope it is correct
The statements which are correct are B, C and E.
What is Relative Frequency?Relative frequency is defined as the ratio of the frequency by the total count of the data values.
We have to find the relative frequency in each option.
A) Frequency of "like snowmobiles" and "like skateboards" = 80
Total count = 160
Relative frequency of "like snowmobiles" and "like skateboards" = 80 / 160 = 0.5 = 50%
B) Frequency of "like snowmobiles" and "do not like skateboards" = 25
Total count = 160
Relative frequency of "like snowmobiles" and "do not like skateboards" = 25 / 160 = 0.15625 = 15.6%
C) Frequency of "like snowmobiles" and "like skateboards" = 80
Total row frequency = 105
The row conditional relative frequencies of "like snowmobiles" and "like skateboards" = 80 / 105 = 0.7619 = 76.19% ≈ 76.2%
D) Frequency of "do not like snowmobiles" and "like skateboards" = 45
Total row frequency = 55
The row conditional relative frequencies of "do not like snowmobiles" and "like skateboards" = 45 / 55 = 0.81818 = 81.82%
E) Frequency of "do not like snowmobiles" and "do not like skateboards" = 10
Total column frequency = 35
The column conditional relative frequencies of "do not like skateboards" and "do not like snowmobiles" = 10 / 35 = 0.2857 = 28.57% ≈ 28.6%
Hence the correct statements are B, C and E.

Jay has an album that holds 500 hockey cards. Each page of the album holds 5 hockey cards. If 17% of the album is empty, how many pages are filled with hockey cards?
Answer: 83
Step-by-step explanation: 17% of 500 is 85. If 17% is empty, that means that you'd take away that 15%. 500 - 85 = 415. If each page holds 5 cards, we need to split those cards up between the pages. 415/5 = 83, so 83 pages will be used.

Answer: 17/19
Step-by-step explanation:
Number of red rocks = 6
Number of orange rock = 1
Number of blue rocks = 4
Number of white rock = 1
Number of yellow rocks = 7
Total number of rocks = 19
Probability of not getting a orange the first time will be (1 - 1/19) = 18/19.
Probability of not getting an orange the second time will be: (1 - 1/18) = 17/18
Probability of not getting an orange on both occasion will be:
= 18/19 × 17/18
= 17/19
