Answer: hii
real :)
Step-by-step explanation:
"While it is not a real number — that is, it cannot be quantified on the number line — imaginary numbers are "real" in the sense that they exist and are used in math. Imaginary numbers, also called complex numbers, are used in real-life applications, such as electricity, as well as quadratic equations."

You spin the spinner twice.
5
2
4
3
What is the probability of landing on a 5 and then landing on a 2?
Write your answer as a fraction or whole number.
Step-by-step explanation:
each combination of 2 specific numbers has the same probability. there is no difference in probability between the individual numbers.
remember, a probability is always desired cases over all possible cases.
we have 4 different possible outcomes every time we spin the spinner.
to get a specific number has the probability of 1/4, because we want 1 specific outcome, and have in total 4 different possibilities.
now, we spin a second time. the probability to get a specific number is again 1/4.
but, if we consider both events to be connected, when we want to know the probability to get 2 specific numbers when spinning twice, we have to multiply the individual probabilities :
1/4 × 1/4 = 1/16
so, the probability to land first on a 5, and then secondly on a 2 is 1/16.
the same as for landing first on a 3, and then on a 5.
the same as for landing first on a 4, and then on a 4 (again).
that is because the individual spin results are independent. the result of the first spin does not impact in any way the result of the second spin (in contrary to e.g. pulling multiple cards without returning the previously pulled cards).
You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable preliminary estimation for the population proportion. You would like to be 90% confident that you estimate is within 4% of the true population proportion. How large of a sample size is required
Answer:
n = 400
Step-by-step explanation:
The formula for the error in our estimate is given by:Standard Error : √ ( p(1-p)/ n)Error = SE = Zα/2 √ ( p(1-p)/ n) where Zα/2= critical value for 95% confidence level = 1.96and we know our error is 3.5 %But we do not the sample proportion p. Then what we can do is give an estimate of p in the absence of any other information.In this case we will use p= 0.5 which is the value that maximizes the expression for the standard error :if p = 0.8 then SE= 0.040 p = 0.3 then SE =0.036 p = 0.1 then SE = 0.030 p = 0.5 then SE = 0.050Substituting3.5/100 = 1.96 x √ (( 0.5 x 0.5 ) /n )3.5/ (100 x 1.96 x 0.5 ) = 1/ √n0.0357 = 1 /√n n = 20²
This is a gardener's floor plan of their backyard. Enter the amount of grass, in square yards

Step-by-step explanation:

what I see immediately is that the area is a combination of multiple simple figures :
1 square on top,
1 smaller rectangle in the middle,
1 larger rectangle at the bottom.
we only need to calculate the areas of all 3 figures and then add then up for the total.
that's it.
the top square is easy :
it is a 3cm×3cm square, so the area is 9 cm²
the bottom rectangle is also easy :
it is a 10cm×3cm rectangle, so the area is 30 cm²
for the dimensions of the middle rectangle we need to think a little bit :
the width (or "height") is clear : 3 cm.
what is the length ?
the answer is given by some other pieces of information in the diagram. look closely : is the length of the middle rectangle not the same as the sum of the side length of the top square (3 cm) and the top side segment left of the top square : 2 cm ?
yes, it is, so the length is 3+2 = 5 cm.
and the middle rectangle is 5×3 = 15 cm².
so, the total area is
9 + 30 + 15 = 54 cm²

The cylinders shown below are similar.
What is the ratio of their side lengths?
What is the ratio of their surface areas?
What is the ratio of their volumes?
Step-by-step explanation:
the scale factor of similar objects apply to every line and side length.
we see here the ratio of small side length to large side length is 3/9 = 1/3.
so the small side length is 1/3 if the large side length.
a surface is airways the multiplication of 2 dimensions. so, the scale factor is to be used twice in this multiplication and therefore squares.
so, small surface to large surface is 1/3 × 1/3 = 1/9.
and a volume is airways the result of a multiplication of 3 dimensions. so, the scale factor is then 3 times in that multiplication and is therefore cubed.
so, small volume to large volume is 1/3 × 1/3 × 1/3 = 1/27

Find the perimeter and area of the figure
Answer:
Perimeter = 34 cm
Area = 60 [tex]cm^{2}[/tex]
Step-by-step explanation:
The equation to find the perimeter of a rectangle is:
P = 2(l + w)
l = length
w = width
To find the length we have to use Pythagorean Theorem:
[tex]a^{2} + b^{2} = c^{2}[/tex]
a = 12 cm
b = ?
c = 13 cm
Plug in and solve for b:
[tex](12^{2})+b^{2} = (13^{2})[/tex]
[tex]144 + b^{2} = 169[/tex] Distribute the squares
[tex]b^{2} = 25[/tex] Subtract 144 from 169
[tex]\sqrt{b^{2} } =\sqrt{25}[/tex] Square root both sides
b = 5 cm
Now that we have found the length, and we know the width, we can find the perimeter:
P = 2(12 + 5) = 2(17) = 34
The perimeter of the rectangle is 34 cm.
To find the area use this equation:
A = lw
Plug in the values for length and width and solve:
A = (5 cm)(12 cm)
A = 60 [tex]cm^{2}[/tex]
The area of the rectangle is 60 [tex]cm^{2}[/tex].

Sanjay rolled a number cube three times with odd numbers representing a boy and even numbers representing a girl. Which statement best describes their simulations? Both simulations have the same theoretical probability of a 3-child family having exactly one girl, but their experimental probabilities may differ. The simulations have different theoretical probabilities of a 3-child family having exactly one girl, and the experimental probabilities they generate may differ. The simulations have different theoretical probabilities of a 3-child family having exactly one girl, but their experimental probabilities will be the same. Both simulations have the same theoretical probability of a 3-child family having exactly one girl, and their experimental probabilities will be the same.
Based on the type of tools that April and Sanjay used, The simulations have different theoretical probabilities of a 3-child family having exactly one girl, and the experimental probabilities they generate may differ.
What will April and Sanjay's simulations lead to?They will have different theoretical probabilities on a single girl being had based on the fact that different instruments were used.
There is also a chance that their experimental probabilities may differ when the experiment is repeated several times because the instruments used will show random and unrelated outcomes.
