51 is the highest multiple you can take from 53

One way to find this out is take 53-30 and you get 23 from this you know 21 is the highest multiple you can get so 30+21 = 51

51/3 is 17 so each student gets 17 blocks and the thus remainder is 2

Another way is to divide 30 and 21 by 3 and add them both together and you will get the same answer

Do always make the numbers easier to solve and save time scrambling..

Step-by-step explanation:

5.

|  \frac{x}{3}  +{ \frac{2}{5} } |   =  2

\frac{x}{3}  =  \frac{6}{5}

5x = 18

x =  \frac{18}{5}

and

x/3=-12/5

x=-36/5

If n is divided by 7 the remainder is 3. What is the remainder if 3n is divided by 7?
Keith_Richards [23]
So, if n Divided by 7 = 3 , then n must be 21, because if you do 3 x 7 it equals 21, so now we know n is 21, then that means its 3 x 21 divided by 7 which is 9. Hope i helped ^-^

If my friend and i went to get ice cream, I have $30 and each ice cream is $5. What equation would help me solve this? I need an
Anna35 [415]
<h3>Hello there!</h3>

Your question asks to make an equation with the information that was given.

<h3>Answer: y = -5x + 30</h3>

In order to make an equation for your question. We would be making an equation with the formula: y = mx + b.

Formula: y = mx + b

m = change

x = amount of ice cream

b = starting value

We would need to gather the key information from the question.

Key information:

You have $30

Each ice cream cost $5

With the information above, we can make an equation for the question.

What we know is that you started with $30, so that means that 30 would be your b value (starting value).

Your equation should look like this:

y = mx + 30

Now, we know that each ice cream cost $5, but since we're paying for the ice cream, we would subtract that from our starting value. This means that our change would be -5, since we are taking away $5 each time we buy ice cream.

Your equation should look like this:

y = -5x + 30

The equation above would be the equation for your question.

We would do nothing to x but just leave it as is, since we don't know how many ice creams you're going to buy.

y = -5x + 30 should be your FINAL answer.

<h3>I hope this helps!</h3><h3>Best regards, MasterInvestor</h3>

8. You recorded the time in seconds it took for 8 participants to solve a puzzle. The times were: 15.2, 18.8, 19.3, 19.7, 20.2,
kirill115 [55]

Answer:

Xbar = 20.813

Median = 19.95

5 - number summary :

Minimum = 15.2

Q1 = 19.05; Q2 = 19.95 ; Q3 = 21.95 ; maximum = 29.4

Standard deviation, s = 4.068

Step-by-step explanation:

Given the data:

X : 15.2, 18.8, 19.3, 19.7, 20.2, 21.8, 22.1, 29.4

Ordered data:

15.2, 18.8, 19.3, 19.7, 20.2, 21.8, 22.1, 29.4

The mean (xbar) :

Xbar = Σx / n ; n = sample size = 8

Xbar = 166.8 / 8 = 20.8125

Xbar = 20.813

The median :

1/2 *(n+1)th term

1/2(9) = 4.5

(4 + 5)th term / 2

(19.7 + 20.2) / 2 = 19.95

The five number summary :

Minimum = 15.2

Lower quartile (Q1) = 1/4(9) = 2.25 ; (2nd + 3rd) term / 2

(18.8 + 19.3) / 2 = 19.05

Median (Q2) = 19.95

Upper quartile (Q3) :

3/4(9) = 6.75 = (6th + 7th) / 2

(21.8 + 22.1) / 2 = 21.95

Maximum = 29.4

The standard deviation, s = sqrt[(x - xbar)²/ (n-1)]

Using calculator ;

s = 4.068
