Answer:
C. 15m
Step-by-step explanation:
if ABCD and EFGH are congruent that means that they are equivalent to each other. If side FG is the base of that trapizoid, and side CD is the base with the measurement of 15m, then we are left to believe that side FG is 15m
Answer:
<h2>
B. 6</h2>
Step-by-step explanation:
I'd like to begin by apologizing for the late reply.
PROCESS:
1) Begin by analyzing the triangle
2) Notice how you can take the sin of 30 to find the hypotenuse
3) sin30= 3/x
4) If you don't see how I did that, a fun trig word play for functions, is
S O/H
C A/H
T O/A
where
S= Sine
C= Cosine
T= Tangent
O= Opposite
H= Hypotenuse
A= Adjacent
so side opposite of 30 is side 3, and the hypotenuse is x.
5) sin30= 3/x = 6
6) Your answer, hypotenuse is 6
BONUS: If you want to find the base length, use Pythagorean theorem.
c=√a2+b2
b=√c2-a2= √6^2 - 3^2= 5.19 or 5.2
Step 1: Find the standard error (SE)
The standard error is given by
![SE=\frac{s}{\sqrt[]{n}}](https://tex.z-dn.net/?f=SE%3D%5Cfrac%7Bs%7D%7B%5Csqrt%5B%5D%7Bn%7D%7D)
In this case,
Therefore,
![SE=\frac{0.76}{\sqrt[]{74}}\approx0.0883](https://tex.z-dn.net/?f=SE%3D%5Cfrac%7B0.76%7D%7B%5Csqrt%5B%5D%7B74%7D%7D%5Capprox0.0883)
Step 2: Find the alpha level (α)
Step 3: Find the critical probability (P*)
Therefore,
Step 4: Find the critical value (CV)
The critical value the z-score having a cumulative probability equal to the critical probability (P*).
Using the cumulative z-score table we will find the z-score with value of 0.995
Hence,
Step 5: Find the margin of error (ME)
Therefore,
Step 6: Find the confidence interval (CI)
Therefore,
Hence there is a 99% probability that the true mean will lie in the confidence interval

Answer:
32
Step-by-step explanation:
The problem statement states that there are four card option two colored envelopes options and four sticker design options and as the greeting card constitutes of one type of card.one colored envelopes and one sticker design then the number of ways Jacqui arrange the greeting card sets can be calculated using the counting principle that is n1*n2*n3. So, the number of ways Jacqui arrange the greeting card sets can be calculated using the counting principle=4*2*4=32 different ways.
Property of Zero because anything multiplied by 0 equals 0. If this is right could I possibly have brainliest? Hope this helped!! :)
