Answer:

Step-by-step explanation:

for us to find the answer we have to find the number that divides evenly to both numbers with no remainder.

2: 21/2= 10.5 you can stop here because you already got an uneven answer

3: 21/3= 7 and 24/3= 8. theres your answer! 3 divides into 21 and 24 evenly with no remainder

4: 21/4= 5.25 you can stop here because you already got an uneven answer

6: 21/6= 3.5 you can stop here because you already got an uneven answer

also because i got it right on oddysseyware :D

Answer:

Step-by-step explanation:

$2 + 1/3t = 1 + 1/4t\\\\2+\frac{1}{3}t=1+\frac{1}{4}t\\\\\mathrm{Subtract\:}2\mathrm{\:from\:both\:sides}\\2+\frac{1}{3}t-2=1+\frac{1}{4}t-2\\\\Simplify\\\frac{1}{3}t=\frac{1}{4}t-1\\\\\mathrm{Subtract\:}\frac{1}{4}t\mathrm{\:from\:both\:sides}\\\frac{1}{3}t-\frac{1}{4}t=\frac{1}{4}t-1-\frac{1}{4}t\\\\Simplify\\\frac{1}{12}t=-1\\\\\mathrm{Multiply\:both\:sides\:by\:}12\\12\times\frac{1}{12}t=12\left(-1\right)\\\\\\Simplify\\r =-12$

balandron [24]

Answer:

<em>The first step is to determine the average </em>

$x= \frac{0,6+0,7+ 0,7+0,3+0,4+ 0,5+ 0,4 +0,2}{8}\\\ x= 0,475$

<em>The exercise says it’s a normal distribution: (n=8)</em>

$s^{2}= \frac{1}{n-1} ((0,6.x)^2+2(0,7-x)^2+(0.3-x)^2+2(0.4-x)^2+(0.5-x)^2+(0.2-x)^2)\\\ \frac{1}{7}*0,235 = 0,0336 \\\\ s= 0183$

<em>According to the exercise, the mean is equal to 0,5 then the value of t of the distribution can be obtained </em>

<em />

$t= \frac{x-u}{\frac{s}{\sqrt{n} }}\\\ t= \frac{0,475 - 0,5}{0,183}\\\ t= -0,3860$

<em>The variable t has 7 grade to liberty, we calculate the p-value as: </em>

$2* P(t < - 0,3860)= \\\ 2* 0,3554 = 0,7108$

This value is very high, therefore the hypothesis is not rejected

Michele is purchasing new clothes for soccer practice for the upcoming season. She buys s pairs of shorts at $14.98 each. She al

Arte-miy333 [17]

Answer:

s14.98 + 92

Step-by-step explanation:

In order to make an expression for this word problem, all you have to do is follow along the steps in the problem:

s14.98 represents how many shorts Michele bought and how much they cost

8 * 11.50 represents how many shirts she bought and what they cost, but we need to simplify, so

8 * 11.50 = 92

Therefore, by adding the shorts and shirt together, we get the expression:

s14.98 + 92

Hope this helps :)

Called ultimate addition, u(x) is defined to be the sum of all digit of an integer until the result is single digit integer. If

slamgirl [31]

<h3>Answer: A) 2</h3>

=====================================================

Work Shown:

u(50654) = 5+0+6+5+4 = 20

u(20) = 2+0 = 2

u(50654) = 2

We want to find all possible values of m such that u(m) = 2 and also m is some two-digit integer.

-----

Possible values of m are: m = 11, m = 20

u(m) = u(11) = 1+1 = 2

u(m) = u(20) = 2+0 = 2

and that's it. There are no other ways to have two positive integers add up to 2.
