I like changing things into decimals, so 7.25-2.75. For the moment, pretend the decimal isn’t there and the equation is 725-275. That equals 450. Now we put the decimal back, so since it is subtraction you keep the decimal in the same place (two spots away from the end). So the answer is 4.5.

Max bought 4 liters of fruit punch for a party.he will serve the punch in glasses that will hold 200 milliliters.how many full g
ss7ja [257]
Hello!
.
1 liter is equal to 1000 milliliter.
So,
4 L = 4000 mL
.
Max bought 4 liter or 4000 mL of fruit punch. To know how many glasses full of fruit punch can he serve, you just need to divide the amount of fruit punch he bought by the amount of fruit punch a glass can hold.
4 L / 200 mL
The dividend and the divisor have different unit so we must make them have the same unit.
4000 mL / 200 mL
= 20
.
Therefore, Max can make 20 full glasses of fruit punch for the party.

If we wanted to create a new 90% confidence interval from a different sample for the proportion of those with a two on one date
slava [35]

Answer: 271

Step-by-step explanation:

The formula we use to find the sample size is given by :-

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2

, where z_{\alpha/2} is the two-tailed z-value for significance level of (\alpha)

p = prior estimation of the proportion

E = Margin of error.

If prior estimation of the proportion is unknown, then we take p= 0.5 , the formula becomes

n=0.5(1-0.5)(\dfrac{z_{\alpha/2}}{E})^2

n=0.25(\dfrac{z_{\alpha/2}}{E})^2

Given :   Margin of error : E= 0.05

Confidence level = 90%

Significance level \alpha=1-0.90=0.10

Using z-value table , Two-tailed z-value for significance level of 0.10

z_{\alpha/2}=1.645

Then, the required sample size would be :

n=0.25(\dfrac{1.645}{0.05})^2

Simplify,

n=270.6025\approx271

Hence, the required minimum sample size =271
