I think ur question is.. If you are making a certain amount u need 2 1/4 flour.. and u need to make half more than that isn't it?

2 1/4= 2.25

Take half of 2. 25= 1.115

Now add 2.25+1.115=3.365

That means you should take 3 cup and a little more than 1/4 cup of flour.I think ur question is.. If you are making a certain amount u need 2 1/4 flour.. and u need to make half more than that isn't it?

Andre went hiking near his house.The first trail he hiked on took him 4.5 miles away from his house. The second trail he hiked t

alukav5142 [94]

Answer: He is 3.8 miles away from his house.

Explanation :

Distance the first trail took him away = (+) 4.5 miles

( We will show it with positive sign as it increase the distance away from the house)

Distance the second trail took him closer = (-) 2.4 miles

(We will show it with negative sign as it decreases the distance)

Distance the third trail took him far away = (+) 1.7 miles

Now , total distance = 4.5-2.4+1.7

= 3.8 miles

∴ He is 3.8 miles far his house.

Over the past several years, the proportion of one-person households has been increasing. The Census Bureau would like to test t

Ganezh [65]

Answer: z =2.39

Step-by-step explanation:

Given :

$H_0: p \leq0.23\\\\ H_a: p > 0.23$

A random sample of 136 households found that 43 consisted of one person.

i.e. Sample size : n= 136

Sample proportion : $\hat{p}=\dfrac{43}{136}=0.316176470588\approx0.3162$

Test statistic for proportion :-

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

$\Rightarrow z=\dfrac{0.3162-0.23}{\sqrt{\dfrac{0.23(1-0.23)}{136}}}\\\\\Rightarrow\ z=\dfrac{0.0862}{\sqrt{0.00130220588235}}\\\\\Rightarrow\ z=\dfrac{0.0862}{0.0360860898734}\\\\=2.38873206552\approx2.39$

Hence, the value of the test statistic: z =2.39
