9 and 12 have a common factor of 3 so 9/12 = 3/4

9 and 12 can both be divided by 3, so the answer would be 3/4

Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol ( mu μ, p, sigma σ) for

ella [17]

Answer:

Null hypothesis: $H_0:\; \mu = 48\; ^\circ\rm F$ .

Alternative hypothesis: $H_1:\; \mu \ne 48\; \rm ^\circ F$ .

Step-by-step explanation:

In hypothesis testing, the alternative hypothesis $H_1$ represents the claim that is being tested. According to the claim in this question, the true (population) mean $\mu$ is "incorrect," or not equal to (" $\ne$ ") the proposed value of $48\; \rm ^\circ F$ . Hence, the alternative hypothesis for this question would be $H_0:\; \mu \ne 48\; \rm ^\circ F$ .

On the other hand, the null hypothesis represents what happens when that claim is disproved; it should always use the equal sign (" $=$ ".) In this question, that's the same as saying that the (population) mean $\mu$ is indeed equal to $48\; \rm ^\circ F$ . Hence, the null hypothesis for this question would be: $H_1:\; \mu = 48\; \rm ^\circ F$ .

Ned help please number 25

zysi [14]

Answer:

$204.11

Step-by-step explanation:

To find 70% of $269.99, multiply $269.99 x .7 = $188.99.

To find the 8% sales tax on $188.99, multiply $188.99 x .08 = $15.12.

Add the $15.12 of sales tax onto the cost of $188.99 = $204.11

If the LCM and the HCF of two numbers are 9 and 3, respectively, what are the numbers?

dlinn [17]

Hey There!

Answer:

HCF = 9 (With the two numbers) - 18,9
LCM = 3 (with the two numbers) - 6,9

Step-by-step explanation:

HCF

If HCF is ''9'' that means that ''9'' is the divisible of two numbers.

So 18 and 19 can be divided by 9 and that's the highest divisible for both factors.

And always remeber the answer is a ''Prime factor.''

LCM

If LCM is ''3'' that means ''3'' is the lowest common multiple out of two numbers.

Hope this helps!

Have a nice Day!:)
