To find the answer you first have to turn 4 1/2 a mixed number into an improper fraction. To do this you must multiply the denominator with the whole number to get 8 after add 1 to get 9. to finish off the improper fraction put the 9 as the numerator and keep the denominator of 2. After this you will have 9/2 ÷ 3/4. Remember Keep Change Flip. this means keep 9/2 change the sign from division to multiplication and flip 3/4 to 4/3. After this you will have 9/2 x 3/4. Now multiply the numerators and multiply the denominators. 9x4 is 36 and 2x3 is 6 you now have 36/6. Lucky for you 36 goes into 6, 6 times. So the answer is 6. If you have anymore questions please dont hesitate to ask :) Hope this helps.

A null hypothesis is a kind of hypothesis used in statistics. It proposes that, in a set of given observations, no statistical significance exists. The null hypothesis attempts to show that no variation exists between variables or that a single variable is no different than its mean. It is presumed to be true until statistical evidence nullifies it for an alternative hypothesis.
So, for this problem, given that three new colors have been proposed for the jeep grand cherokee vehicle. those are silvered-blue, almond, and willow green, the null hypothesis is:
H0: b. that there is no preference between the colors.
Answer:
3 +9 does not belong because it doesn't equal 10 like the rest of them do.
The total arc length around a circle is 360 degrees. So, these 3 arc with expressions given will all add up to 360.
(-2 + 8x) + (10x + 10) + (10x - 12) = 360
28x - 4 = 360
28x = 364
x = 13
Now that we know the value of x, we can plug that value into the expression for arc LM and solve for the measure.
LM = 10x - 12
LM = 10(13) - 12
LM = 118 degrees
Hope this helps! :)
