I included a screenshot with the question, thank you!!

The "Let's Roll" game uses a number cube with the numbers 2,4,6,8,10, and 12. There are prizes for rolling any number less than

deff fn [24]

There is a 33.3% chance of rolling a number less than 6. It’s 2/6, which is reduced to 1/3. = that to x/100, multiply 1 x 100, and divide that by 3. So it’s 100 divided by 3, and that’s 33.3, which is the percentage.

A recipe includes 66 cups of flour and two thirds 2 3 cup of buttermilkbuttermilk. Write the ratio of the amount of flour to the

beks73 [17]

Answer:

The ratio of the amount of flour to the amount of buttermilk=99:1

Step-by-step explanation:

Step 1: Determine quantity for each recipe

Quantity of flour=66 cups

Quantity of buttermilk=2/3 cups

Step 2: Calculate the total quantity of recipe

The expression for the total quantity is;

T=f+b

where;

T=total quantity of recipe

f=quantity of flour

b=quantity of buttermilk

In our case;

T=unknown

f=66 cups

b=2/3 cups

replacing;

T=(66)+(2/3)=66 2/3 cups

Step 3: Determine fraction of each

fraction of buttermilk=(2/3)/(66 2/3)=1/100

fraction of flour=66/(66 2/3)=99/100

Step 4: Determine ratio of flour to buttermilk

Amount of flour:amount of buttermilk

(99/100):(1/100)

The ratio of the amount of flour to the amount of buttermilk=99:1

Population A and Population B both have a mean height of 70.0 inches with an SD of 6.0. A random sample of 50 people is picked f

Alex

Answer:

Sample mean from population A has probably more accurate estimate of its population mean than the sample mean from population B.

Step-by-step explanation:

To yield a more accurate estimate of the population mean, margin of error should be minimized.

margin of error (ME) of the mean can be calculated using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic in the given confidence level(z-score or t-score)

s is the standard deviation of the sample (or of the population if it is known)

N is the sample size

for a given confidence level, and the same standard deviation, as the sample size increases, margin of error decreases.

Thus, random sample of 50 people from population A, has smaller margin of error than the sample of 20 people from population B.

Therefore, sample mean from population A has probably more accurate estimate of its population mean than the sample mean from population B.
