Answer:
The probability of drawing 3 tens one after another without replacing them is 1/5525
Step-by-step explanation:
In a pack of 52 cards, there are 4 cards that are 10, so the probability of drawing one ten [p(10)] = 4/52
Therefore:
The first draw, P(10) = 4/52
Now, at this point you have taken out one of the cards with a number 10 printed on it, so we are left with 51 cards in total and 3 cards of 10.
The second draw, p(10) = 3/51
Now, we have 50 cards left and a total of 2 cards with a number 10 printed on it.
The third draw, p(10) = 2/50
Hence, the probability of drawing out 3 number 10 cards without replacement is:
4/52 * 3/51 * 2/50 = 1/5525
The probability of drawing 3 tens one after another without replacing them should be 1/5525.
Calculation of the probability:Since we know that
In a pack, there are 52 cards and there are 4 cards that are 10,
so the probability of drawing one ten [p(10)] = 4/52
Now it should be left with 51 cards in total and 3 cards of 10.
So, The second draw, p(10) = 3/51
and, The third draw, p(10) = 2/ 50
Thus, the total probability is
= 4/52 * 3/51 * 2/50
= 1/5525

Micheal is buying Presents for a gift exchange for his four friends. He would like to spend less than $160 total. On average, how much can he spend on each person? Write out the Inequality as well.
Answer:
Micheal will spent 40 $ on each of his friends
Step-by-step explanation:
160$÷4=40$
why because there is 160 dollars to spend and there are 4 friends now you need to divide that to get the amount of money you need.
Answer:
x≤40. He can spend about $40 on each friend
Step-by-step explanation:
I got this because a number x is the amount of money he can spend on a friend on average. The inequality is then written like 4x≤160. You then try to get "x" on its own by dividing both sides by 4 (both sides being 4x and 160). then you get the average amount Michael can spend on his friends.

3.17, because there are about 1.056 quarts in one liter.
1.056 times 3 = 3.168, which, rounded to the nearest hundredth, is 3.17.
hope this help :)
After rounding off the obtained value, the value obtained in quarts will be equal to 3.17 qt.
What is rounding off values?The act of simplifying a number so that its value remains near to what it was is known as rounding. The outcome of rounding off a figure is less precise but simpler to utilize. They directly involve if a number's digits are taken into account while rounding it.
As per the given information in the question,
As we know,
1 liter = 1.057 quarts
Then, the number of quarts in 3 L will be equal to,
3 × 1.057

Answer: ___
-1/3x + 1/4
Answer:
x/3 +1/4+-2x/3
Step-by-step explanation:
Combine multiplied terms into a single fraction
1/3x+1/4-1*2/3*x
1x/3+1/4-1*2/3*x
Multiply by 1- 1x/3+1/4-1*2/3*x x/3+1/4-1*2/3*x
Multiply the numbers- x/3+1/4-1*2/3*x x/3+1/4-2/3x
Combine multiplied terms into a single fraction-
x/3 +1/4-2/3x x/3+1/4+-2x/3

Jack is making lemonade and mixes 3 liters of sugar with 8 liters of lemon juice. Which ratio of liters of sugar to lemon juice will make the concentration of lemonade?
A: 15 to 32
B: 9 to 6
C: 12 to 32
D: 6 to 24
Answer:
C. 12 to 32
Step-by-step explanation:
The simplified ratio would be 3:8
So multiply 3*4=12
And multiply 8*4=32
12:32
The reason the other ones wouldn't work is because 3 and 8 are not multiplied by the same number
For example
A.)15 to 32 wouldn't work because there not multiplied by the same number
3*5=15
8*4=32

Answer:
is this a test
Step-by-step explanation:
Answer:
1. No Solution, 2. Unique Solution, 3. Infinitely Many Solutions
Step-by-step explanation:
1. If two lines are parallel, they share no common points, and no answers.
2. y = 3x + 4 and y = 1/2x + 5 are not parallel and not equivalent, therefore, they have one solution.
3. Simplified, the two equations are z + 2y = 10 and z + 2y = 10, therefore they are equivalent and they have solutions for as far as the line extends, which is infinitely.

Answer:
I got u fam any questions? hit me up
Step-by-step explanation:
so you're learning about plotting graphs. If the hot female lifeguard makes 8.50 an hour, then the table would be 1 in the hours place and 8.50 in the money's place. Then for hour number 2, you multiply 8.5 by 2 and you get 17.
When you plot the numbers on the x-axis (horizontal line in the graph) label the intervals by 1s so 1, 2, 3, 4, etc. for the y-axis (vertical line in the graph), start by 2, then go by intervals of 2 which would be 2, 4, 6, 8, 10, etc. Now, when u plot the points, label the x axis "hours" because that is the independent quantity and the money is dependant on the number of hours, so label "dollars made" on the y-axis. From the table you will have (1, 8.5) which will be your first point and plot it in the graph use this as a reference
(x coordinate, y coordinate) the one on the right will always be the y coordinate and the one on the left will always be the x coordinate. Draw the line from (0,0) to (1, 8.5) so go up 8.5 in numbers and right 1 and keep drawing until you reach the end of the graph. Number 4 would be 2x+1. when u see f(2), that means to replace x with the number in the parentheses which would be 2(2)+1=5

Ms.Alvarez's math class surveyed 10 students in 6th grade and 10 students in 7th grade. The class asked how many hours of chores each student did the previous weekend. The results were displayed in two histograms.
Mean is greater for grade 7.
Median is greater for grade 7.
So, the correct options are B and D.
What is mean and median?"The mean is the number you get by dividing the sum of a set of values by the number of values in the set.
The median is the middle number in a set of values when those values are arranged from smallest to largest."
Mean for grade 6 is
= [tex]\frac{1+2+3+1+1+1+1}{7}[/tex]
= [tex]\frac{10}{7}[/tex]
Mean for grade 7 is
= [tex]\frac{1+2+5+2}{4}[/tex]
= [tex]\frac{10}{4}[/tex]
From both we get, Mean is greater for grade 7
Median for grade 6 is 1
Median for grade 7 is
= [tex]\frac{2+5}{2}[/tex]
= 3.5
From both we get, Median is greater for grade 7
So, the correct options are B and D.

Answer:
Step-by-step explanation:
Since this is a test, I'll give a hint.
This problem can be a little confusing, but thats ok! The problem is trying to make two models, (each model is a number) and asking you to find what the addition sentence is.
If that makes you confused, then that's probably the right response! The first thing you would need to know is what are they dividing the whole circles of? Thirds? Seconds? Sixths?
You would then need to know how many whole numbers are there. "Whole numbers" are basscially fully shaded circles.

x = 5
Step-by-step explanation:

The only thing that makes x true is 5. (This might not help if I read the question wrong.)
Answer:
6x-5=4x+5
x=5
Step-by-step explanation:
6x-5=4x+5
Subtract 6x from both sides
-5=-2x+5
Subtract 5 from both sides
-10=-2x
Divide by -2 on both sides
