Answer:
Step-by-step explanation:
Normal. A common pattern is the bell–shaped curve known as the “normal distribution.” In a normal distribution, points are as likely to occur on one side of the average as on the other. Be aware, however, that other distributions look similar to the normal distribution. Statistical calculations must be used to prove a normal distribution.

A submarine submerges from the surface of the sea at the rate of 10 m/min. How long will it take to reach 300 m below the sea level
Answer:
answer is 300m/30min
Step-by-step explanation:
300\10=30
Given the speed of the submarine, the total time it will take to cover the the given distance is 30 minutes.
How long will it take the submarine to reach 300 m below the sea level?Using the expression Time = distance / speed.
Given that;
Speed = 10m/minDistance = 300mTime = ?Time = distance / speed
Time = 300m / 10m/min
Time = 30 minutes
Given the speed of the submarine, the total time it will take to cover the the given distance is 30 minutes.

Answer:
Step-by-step explanation:
2.
area= length x width
area = 5.4 x 5.4 = 29.16 cm^2
perimeter is adding up all the sides
perimeter= 5.4+5.4+5.4+5.4 = 21.6 cm
1. area= 7.4 x 5.1 = 37.74 yds^2
perimeter= 7.4+7.4+5.1+5.1 = 25 yds

Answer:
14. It is 116.80
because the formula is π x r² so 6.1² x 3.14= 116.8394
15. It is 50.20
because the formula is r²*3.14 and the radius if half of the diameter and the diameter is 8 and half of it would be 4 and 4²=16 so 16*3.14= 50.24

Answer:
1.) 45 2.) 93 3.) 80
Step-by-step explanation:
Answer:
Triangle 1: 45
Triangle 2: 93
Triangle 3: 80
Step-by-step explanation:
All triangle angles must equal 180 degrees!!!
Now lets solve :)
Triangle 1
45 + 90 + x = 180
135 + x = 180
180 - 135 = 45
x = 45 :)
Triangle 2
36 + 51 + x = 180
87 + x = 180
180 - 87 = 93
x = 93 :)
Triangle 3
63 + 37 + x = 180
100 + x = 180
180 - 100 = 80
x = 80
Have an amazing day!!

Directions
Open the compass legs to some radius more than 1/2 the length of WX. It does not matter what the exact value as long as it is more than 1/2 way.
Put the pin end on X and draw an arc with the penciled end. Make sure that the arc you are drawing is both above and below the line WX.
Transfer the pin end to W and draw another arc so that the new arc intersects the first arc drawn from x. Make sure that the new arc is above and below the line WX
With the straight edge as a guide, draw a line between the two intersected arcs. Where lines intersect each other is where the perpendicular bisector intersects WX
Reupload of a question. I wasted my points on the other one.
The area of a square floor on a scale drawing is 16 square centimeters, and the scale drawing is 1 centimeter:3 ft. What is the area of the actual floor? What is the ratio of the area in the drawing to the actual area?
Answer:
First of all you need to identify the scale drawing that is 1cm: 3ft so if it is 16 you multiply 16 times 3 which is 48. Then, you just multiply 16cm( 1cm/3ft) making the answer to be 5.3333 or 5.3 so hope this is for the area of the actual floor and hope this answer help you so sorry if i did not get it right because i did my best.
Step-by-step explanation: sorry if i did not answer the second part if the question but thanks for helping you in one part of the question.
Find the mistake: two-step equations
5 stars for correct asnwer- there r three choices- step 1, step 2, and "Ling did not make a mistake."
have a great day byeeee
Answer:
Ling did not make a mistake.
Step-by-step explanation:
[tex]\bf -2q+11=-32[/tex]
[tex]\bf -2q=-43[/tex] (Step 1)
[tex]\bf q=21.5[/tex] (Step 2)
First step, Ling subtracted 11 from both sides which's correct.
Then she divided each side of the equation by -2. correct*
Hence, Ling didn't make a mistake.

Can anyone solve this?
Answer:
324 inches squared
Step-by-step explanation:
The question is most likely asking for the surface area of the rectangular prism.
The Formula for this is:
2(wl+hl+hw)
h = 6in
w = 5in
l = 12in
Plug in the varibles:
2( 5*12 + 6*12 + 6*5)
Simplify:
2( 60 + 72 + 30) =
2(162) =
324
So the answer is 324 inches squared!
Hope this helps! :)
Answer:
The surface area of the rectangular prism is: 324
The volume of the rectangular prism is: 360
Step-by-step explanation:
Surface area is calculated with the formula:
2(wl + hl + hw)
w*l = 6*12 = 72
h*l = 5*12 = 60
h*w = 5*6 = 30
Now add up 72, 60, and 30.
72+60+30 = 162.
This leaves us with the equation:
2(162)
So, we multiply 2 and 162 to get the surface area.
2*162 = 324.
For the volume, we multiply the length, width, and height altogther.
l*w*h
So, we plug in the values, and multiply:
12*6*5 = 360
The volume is 360 in^3
Below is the table of values of a function. Write the output when the input is n .
Answer:
The ouput of n would be 14 if we make n = 12
Step-by-step explanation:
The input plus two more is equal to the output
1. Since the input is a variable we can make any number the input
2. I'll use 12 as the input
3. According to the table The output is always equal to the input +2
4. 12 +2 = 14
5. The output of n would be 14 if we used 12 as an input.
Write the function h(x) if f(x) = radical x is reflected across the y- axis, stretched vertically by a scale factor of 6, and then translated 4 units down.

How do I make a mixed number into an improper fraction?
Answer:
Multiply the whole number with the denominator of the proper fraction. Add the numerator of the proper fraction to this product to obtain the numerator of the improper fraction.
Explanation:
Let us convert 3¼ into an improper fraction.
Numerator of the improper fraction = (3 × 4) + 1 = 13
The denominator of the fraction will stay the same = 4
Hence 3¼ converted into an improper fraction will be 13/4

Scott and Isaac went to the school carnival. Scott ride on 5 rides and played 4 games. Isaac rode on 7 rides played 2 games. If Scott payed 19 tickets and Isaac payed 23 tickets, how many tickets did a ride cost?
Answer:
The cost of the rides are 3 tickets
And 1 ticket per game
The ride and game cost 3 tickets and 1 ticket for each respectively.
Step-by-step explanation:
Step 1 of 5
Let a be the number of tickets per ride costs. And b be the number of tickets per game costs.Thus from the given, we get the equations. For Scott, 5a+4b=19 For Isaac, 7a+2b=23
Step 2 of 5
Multiplying the equation 2 by 2, we get 5a+4b=19→1 14a+4b=46→2
Step 3 of 5
By subtracting both the equations, we get
(−)5a+4b=1914a+4b=46
_____________
−9a =−27
a=−27−9⇒a=3
Step 4 of 5
Substituting the above value in the equation 1, we get5(3)+4b=1915+4b=194b=19−154b=4b=44⇒b=1
Step 5 of 5
The solution is (3,1).The cost of the rides is 3 tickets per ride.The cost of the games is 1 ticket per game.
sorry its really confusing this how I was taught tho.
a company hires full-time and part-time workers. The ratio of full-time to part-time workers employed at the company is 10:3. Kaylee knows there are 364 total workers at the company. Determine how many more of the workers are full-time than part-time.
Part time = 280
Full time = 84
Step-by-step explanation:
It says it’s 10:3
So I divided 364 into 13 parts so I would be able to put them in 10/3 parts
Each part has 28 so I times it based on what number I needed in the ratio
What is the scale factor from Figure A to Figure B?
Answer:
figure B is ×3 larger than figure A
Step-by-step explanation:
if you divide the lengths of the sides of figure B by the sides of figure A, you will get 3.
Find the length of two common sides:
Height of A = 2
Height of B = 6
scale factor from A to B = 6/2 = 3
answer: scale factor = 3
