Athere are 15. A way to look at it is that for every photo there is 3 poses. So 3+3+3+3+3. That is 15 and the correct answer.

g Suppose you wish to perform a hypothesis test for a population mean. Suppose that the population standard deviation is known,

NikAS [45]

Answer:

z-test.

Step-by-step explanation:

We want to perform an hypothesis test for a population mean.

In the case that the <u>standard deviation of the population is known</u> and the population distribution is normal, even if the sample is small, <u>we will use a z-test</u>.

The usual case is to not know the standard deviation of the population, in which case a t-test is adequate instead of a z-test, taking into account the degrees of freedom of the sample.

What is the standard form of the equation of a circle that has its center at (-2,-3) and passes through the point (-2,0)?

rusak2 [61]

So the radius is from (-2, -3) to (-2, 0) which is a distance of 3The general form for the equation of a circle is: $(x - h)^2 + (y - k)^2 = r^2$ , where the center is (h, k)Plug into the general equation

$(x + 2)^2 + (y + 3)^2 = 3^2 \\ (x + 2)^2 + (y + 3)^2 = 9$

Well, the last digit in the product will only come from the last digits of the numbers that you're multiplying together. So for 0.303 & 4.48, that last digits are 3 & 8 so that last digit in the product would come from
$3 \times 8 = 24$
So 4. There are only two options that end in 4, 1.35744 & 0.13574. You can by the magnitude of the numbers that it isn't as small as 0.13574 so the answer must be 1.35744.

-10+square root of x+8 = -4 what is the solution of the equation

dezoksy [38]

$-10 \sqrt{x+8} =-4 \\ \sqrt{x+8}= \frac{-4}{-10} \\ x+8=(\frac{4}{10})^{2} \\ x=(\frac{4}{10})^{2}-8 \\ x=-7.84$
