Answer: (2x - 1)(3x - 4)
(split -11x as -8x and -3x)
Step-by-step explanation:
I am assuming that it is actually 6x^2 - 11x + 4
To find out how to split the middle term: The two numbers should multiply to a*c (6*4 = 24) and add to b (-11)
-8, -3 works
(6x^2 - 8x) + (-3x + 4)
2x(3x - 4) + -1(3x - 4)
(2x - 1)(3x - 4)

Answer with explanation:</h2>
Let p be the proportion of of all adults in the town that have been exposed to this strain of the flue .
As per given , we have

∵
is two-tailed , so the test is a two-tailed test.
Test statistic :

, where p= population proportion
= sample proportion
n= sample size
Put n= 6 and
and p=0.08


P-value for two-tailed test : 2P(Z>|z|)
=2P(Z>|-0.415|)
=2P(Z>0.415)
=2[1-P(Z≤0.415)] [∵ P(Z>z)=1-P(Z≤z)]
=2(1-0.6609) [ by z-table]
=0.6782
Decision : Since the p-value(0.6782) is > significance level(0.01) , so we fail to reject the null hypothesis.
We conclude that that we do not have sufficient evidence to support the claim that the proportion of all adults in the town that have been exposed to this strain of the flue differs from the nationwide percentage of 8%.
Answer:
The total of men in the squadron are 203
Step-by-step explanation:
To solve this problem we need to use the rule of three:
The total of men in a squadron of 100 (81+19) is 81, so how many men for a squadron of 250:
<u>81 </u> : <u> x </u>
100 250
Lets make an X in the divisions:
<u>81 </u> X <u> x </u>
100 250
If you have the two numbers at the ends of the X they are multiplied and divided by the one left alone.
81*250/100
=203
6*30 = 180
8*20 = 160
9*10 = 90
180+160+90 = 430 stickers
