Hey there!

To solve for the solutions of your inequality, divide both sides of your inequality by -3 in order to isolate the value of x:

-3x≥36
÷-3 ÷-3

x≤12
**Note: in inequalities, if you ever divide or multiply a number that is negative, you must flip the inequality sign. In this case, because you have divided -3 from both sides, you must flip the inequality sign from ≥ to ≤.

Therefore, your solutions to your inequality would be x≤12.

Hope this helps, and have a nice day! :)

What is the area of a semi circle that has a diameter of 1 1/2?

SVEN [57.7K]

Answer:

$A=0.8836$

Step-by-step explanation:

Area of circle:

$\pi r^2$

By using the area of a circle, we can get the area of a semicircle:

$\frac{\pi r^2}{2}$

Let's convert the mixed fraction to an improper fraction and then a decimal:

$1\frac{1}{2}$ = $\frac{3}{2}$ = $1.5$

Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:

$\frac{1.5}{2} =0.75$

Now we have the radius, so we can plug in our values and find the area:

$\frac{\pi0.75^2}{2} = 0.88357293$

$A=0.88357293$

hammer [34]

Answer:

$s^2_p = \frac{9*0.3^2 +9*0.4^2}{10+10-2}=0.125$

$s_p =\sqrt{0.125}=0.354$

$(2.7 -2.4) - 2.1*0.354\sqrt{\frac{1}{10}+\frac{1}{10}}=-0.032$

$(2.7 -2.4)+ 2.1*0.354\sqrt{\frac{1}{10}+\frac{1}{10}}=0.632$

Step-by-step explanation:

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Data given

$\bar X_M = 2.7$ represent the sample mean for men
