Answer:
AD = 6m
Step-by-step explanation:
Sin(30) = AD / 12
Sin(30) * 12 = AD
6 = AD
Hope this helps!
Find AD.
[tex] \sf a. \: 2\sqrt{3} \: m[/tex]
[tex] \sf b. \: 3 \sqrt{3} \: m[/tex]
[tex] \sf c. \: 6 \: m[/tex]
[tex] \sf d. \: 6 \sqrt{3} [/tex]
____________________
Solution :-Given Information :-∠DCB = 30°∠BDC = 90°∠ABC = 90°BC = 12 mTo Find :-The Length of AD Calculation :-Here, Sin θ is 30°
Sin = [tex] \bf \frac{perpendicular}{hypotenuse} [/tex]
Here, θ is 30°
Substituting the values, We get,
∴ Sin ( 30 ) = [tex] \sf \frac{AD}{BC} [/tex]
Substituting the value of BC as 12, We get,
⇒ Sin ( 30 ) = [tex] \sf \frac{AD}{12} [/tex]
Transposing 12 to Left Hand Side, We get,
⇒ Sin ( 30 ) × 12 = AD
Calculating further, We get,
⇒ AD = 6 m
∴ AD = 6 m
____________________Final Answer :-The Length of AD is 6 m

Question Hannah wanted to investigate whether there was a difference in the time spent in the checkout line between two grocery stores in a large city. She went to Grocery Store J on a Monday morning and recorded the time, in minutes, it took 30 customers to go through a checkout line. Then she went to Grocery Store K on Monday afternoon and recorded the time it took 30 customers to go through a checkout line. Hannah calculated the mean number of minutes for the customers in each line. She intends to conduct a two-sample t-test for a difference in means between the two stores. Have all conditions for inference been met?
Answers
Answer:
Yes. All the conditions for inference have been met.
Step-by-step explanation:
The conditions for inference are:
a) The sample must be random. The selections of the 30 customers in each Grocery Store were not biased in any way.
b) The sampling distribution must be approximately normal.
c) The observations of the samples were independent.
d) Adequate of sample size. 30 customers represent an adequate sample
e) The variances are not known as they were disclosed in this case.

The mass of the 850 nails is 442 x 10⁻² kilograms.
What is multiplication?The mathematical operation of multiplication is arithmetic. Additionally, it involves repeating the same forms of statements.
Example: 2 + 3 signifies that 2 is multiplied by 3 or that 3 is multiplied by 2 times.
A carpenter bought 850 nails.
Each nail has a mass of 5.2 x 10-3 kg.
To find the total mass:
Use multiplication operation,
850 x 5.2 x 10⁻³
= 4420 x 10⁻³
= 442 x 10⁻²
Therefore, the mass is 442 x 10⁻² kilograms.

No links, docs, files, drives etc
I will mark the correct answer brainlyest
You earn many points
Answers
========================================================
Explanation:
A square has all four sides that are the same length. So all four sides are 12 cm
area = side*side = 12*12 = 144 cm^2
Or you could say
area = (side)^2 = (12)^2 = 144 cm^2
Squaring a number is the same as multiplying it by itself. Hence the name "square" refers to a side length pairing up with its corresponding area value.
---------
Side note: The perimeter is 4*(side) = 4*12 = 48 cm. It's possible that choice B is put in there as a trick answer.
B
If you do 4x12 you will end up with 48
Use the information giving in the figure to find the length FH. If applicable, round your answer to the nearest whole number.
The lengths on the figure are not drawn accurately.
Answers

Answer:
FH = 16
Step-by-step explanation:
ΔGHE is a 5-12-13 triangle.
ΔEHF is a 3-4-5 triangle with a scale factor of 4, so side FH is 4·4 = 16 units.
_____
(3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17) are all commonly used Pythagorean triples. The first two on the list are used in these triangles.
If you like, you can work out the numbers using the Pythagorean theorem, which tells you the square of the hypotenuse is equal to the sum of the squares of the other two sides.
For ΔEHG, that is ...
GE² = EH² + HG²
13² = EH² + 5²
EH² = 13² -5² = 169 -25 = 144
And for ΔEHF, ...
FE² = EH² +HF²
20² = 144 + HF²
400 -144 = HF² = 256
HF = √256 = 16
The length of side FH is 16 units.
