6 0

Answer:

30, 42

Step-by-step explanation:

"The Highest Common Factor (HCF) of my two numbers is 6"

The only factors the two numbers have in common are 2 and 3. Each number must have 2 and 3 as factors.

first number = 2 * 3 * ...

second number = 2 * 3 * ...

Since both numbers contain a 2 as a factor, both numbers must be even. The lowest common multiple is a multiple of 15, but it must be an even multiple of 15.

Multiples of 15: 15, 30, 45, 60, 75, 90, ...

We are interested only in the even multiples of 15: 30, 60, 90, ...

first number = 2 * 3 * 5 = 30

second number = 2 * 3 * 7 = 42

Example: 30, 42

Violet made cookies for the bake sale. 7/10 of the cookies are chocolate chip. 3/4 of the remaining cookies are sugar. What frac
FromTheMoon [43]
We know that 7/10 of the cookies are chocolate chip, so that means there are 3/10 of the cookies left.
We now want to find what 3/4 of 3/10 is.
We can do this by multiplying both fractions
3/4x3/10 (we just multiply across) to get 9/40.
We cannot simplify this answer, so our final answer is 9/40 of the cookies are sugar cookies.

A researcher is interested in determining if the more than two thirds of students would support making the Tuesday before Thanks
Yakvenalex [24]

Answer:

The null hypothesis is, {H₀}: p = 0.66, H₀: p = 0.66 .

The alternative hypothesis is, {Hₐ}: p > 0.66, Hₐ​: p > 0.66

Step-by-step explanation:

Let p represent the proportion of students who are supportive of making the day before Thanksgiving a holiday.

Since two populations are considered, the alternative hypothesis for the difference of the means of the two populations has to be stated.

The proportion of two-third students are supportive of making the day before Thanksgiving a holiday is p = 0.66 obtained as shown below:

The null hypothesis is,

{H₀}:p = 0.66, H₀​: p = 0.66

The alternative hypothesis is,

{Hₐ:p > 0.66, Ha​: p > 0.66

The null hypothesis is, {H₀}: p = 0.66, H₀: p=0.66 .

The alternative hypothesis is, {Hₐ}: p > 0.66, Hₐ​: p > 0.66
