Unit: Inference comparing two groups or populations Unit test Owen lives in New York City and his brother Karson lives in Boston. They both complained about the high prices of avocado in their neighborhoods, so they decided to test whether there's a difference in the average price of avocado. Each of them took a random sample of shops in their neighborhoods and got the price of avocado from each shop. Then, they calculated the average price in each group. Assume that all conditions for inference have been met. Which of these is the most appropriate test and alternative hypothesis?​

Answer:

The probability that Tara will select a blue marble from each bag is [tex]\frac{2}{27}[/tex].

Step-by-step explanation:

Since there are 15 marbles in the first bag and 9 marbles in the second bag, that means there are a total of 135 different combinations of one marble from each bag. Since there are 5 blue marbles in the first bag and 2 blue marbles in the second bag, there are 10 different possible combinations of one blue marble from each bag. The probability that Tara will select a blue marble from each bag can be represented as [tex]\frac{10}{135}[/tex] or [tex]\frac{2}{27}[/tex].

Answer:

SO first we need to get our numbers.

WE see 20.9 and 10.We learned in school that when

you multiply decimals itll show the placr its in.

So it basically shows you the answer.

Now lets divide, 20.9 divided by 10=2.09

Hope this helped my g!

Step-by-step explanation:

The inequality the represents the expression -12d < - 6 is d < 1/2.

Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), larger than (or greater than or equal to), or not equal to signs are used in place of the equal sign. Equations are not always balanced on both sides using a "equal to" sign in mathematics. Occasionally it might be about a "not equal to" connection, meaning that something is superior to or inferior to another.

The given inequality is -12d < - 6.

The inequality can be written as:

d < -6/ -12

d < 1/2

Hence, the inequality the represents the expression -12d < - 6 is d < 1/2.

[tex] \large \boxed{ \boxed{ \tt{g(4) = - \frac{16}{3} \longrightarrow \: \: Improper \: \: Fraction \: \: }}} \\ \large \boxed{ \boxed{ \tt{g(4) = - 5 \frac{1}{3} \longrightarrow \: \: Mixed \: \: Fraction \: \: }}}[/tex]

Step-by-step explanation:

We are given the function below:

[tex] \large{g(x) = \frac{4x}{3x - 15} }[/tex]

To find g(4), we simply substitute x = 4 in the equation.

[tex] \large{g(4) = \frac{4(4)}{3(4) - 15} }[/tex]

Then evaluate the value and simplify in the simplest form.

[tex] \large{g(4) = \frac{16}{12 - 15} } \\ \large{g(4) = \frac{16}{ - 3} } \\ \large{g(4) = - \frac{16}{3} }[/tex]

Therefore, the value of g(4) is - 16/3

Mixed Fraction Form

I hope this may be helpful

Answer:

it is 1/36

Step-by-step explanation:

if you want to get doubles, you have a chance of 1 out of 6 on each die. All you have to do from here is multiply them

1/6*1/6=1/36

Answer:

it should be d. 315

Step-by-step explanation:

to find the volume, we need to multiply length x width x height. the base is both width and height together, so if we just multiply the base and the height we should get the volume which would be 315 cubic centimeters.

Answer:

280/4 = 70 miles per hour. Next, take the unit rate and multiply it by the number of hours you are trying to find. In this case, you are trying to find 6 hours and 30 minutes, but this can also be rewritten as 6.5, since 30 minutes is half an hour. So, in 6.5 hours, the car can go 455 miles

Answer:

Rs 1400

Step-by-step explanation:

Let us take the required number be x. According to question ,

=> 25% of x = Rs 350

=> 25/100 × x = Rs 350

=> x = Rs 350 × 100 / 25

=> x = Rs 1400
