What is the Mean, Median, Mode, and Range for number 4
Please help
Answer:
Mean: 63. Median: 69. Mode: 41. Range: 51.
Step-by-step explanation:
The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list. The "range" of a list a numbers is just the difference between the largest and smallest values.
Hope this helps!

D y = 9.50x + 139.98
Answer:
D. y= 9.50x + 139.98
Step-by-step explanation:
69.99 x 2 = 139,98
How many grams are 7.00 x 1022 molecules of NaOH?
Answer:
46.5
explanation
6.022*10^23 molecules=40g.
7.00*10^23=40*7.00*10^23/6.022*10^23 g =46.5 g
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 4.65g are 7.00 x 10²² molecules of NaOH.
What is mole?The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample.
we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number
mole =given number of atoms ÷ 6.022×10²³(Avogadro number)
given number of atoms of NaOH= 7.00 x 10²² atoms
Substituting the values
mole=7.00 x 10²²÷ 6.022×10²³
mole =0.116 moles of NaOH
mass of NaOH= Molar mass of NaOH× moles of NaOH
= 40 × 0.116
= 4.65g
Therefore, 4.65g are 7.00 x 10²² molecules of NaOH.

a sphere and a cylinder
Answer:
A cylinder and 2 half spheres
Step-by-step explanation:
Using my eyes, I see 1 cylinder and 2 half spheres at the ends of the cylinder.
The shapes that combined to form the comppsite figure are a Cylinder and two half Sphere.
Option A) A cylinder and 2 half spheres is the correct answer.
What is a cylinder and a hemisphere?A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
A hemisphere is gotten when a sphere is cut into two equal halves. It is half of a shere.
From the Image, one can see that a cylinder and two hemispheres combined to form the composite figure.
Hence, the shapes that combined to form the comppsite figure are a Cylinder and two half Sphere.

Step-by-step explanation:
A swim instructor would like to test the effect of a new swim technique versus the standard technique for a group of 25 competitive swimmers.
The swim instructor divides the students by class (junior or senior), and then randomly allocates half of the 14 juniors and 5 of the 11 seniors to receive instruction on the new technique.
During swim practice, the instructor times the juniors as they race against each other to see if those who learned the new technique outperform their peers. The instructor does the same for the seniors.
At the end of practice, the instructor compares the average swim time for both juniors and seniors among those who did and did not use the new technique.
A) The instructor should place the 25 student names on slips of paper and place them in a hat. Twelve of the slips should be drawn out and those students should receive the instruction on the new technique.
B) The instructor should place the names of the 14 juniors on slips of paper and place them in one hat. The 11 seniors’ names should be placed on slips of paper and placed into a separate hat. The instructor should randomly select 7 juniors and 5 seniors to receive instruction on the new technique.
C) For each student, the instructor should flip a coin. If the coin lands on heads, the student will receive instruction on the new technique. If the coin lands on tails, the student will not receive instruction on the new technique.
D) The students should line up alphabetically and count off by 2s. Every student who gets a 1 will receive instruction on the new technique. Every student who gets a 2 will not receive instruction on the new technique.

5 divided by 14?
......................................
Answer:
0.3571
Step-by-step explanation:
Step 1: Start by setting it up with the divisor 14 on the left side and the dividend 5 on the right side like this:
14[tex]\sqrt{x}[/tex]5
Step 2: The divisor (14) goes into the first digit of the dividend (5), 0 times(s).
Therefore, put 0 on top:
14[tex]\sqrt{x}[/tex]0 5
Step 3: Multiply the divisor by the result in the previous step (14 x 0 =0) and write that answer below the dividend.
14 0
[tex]\sqrt{x}[/tex]5
0
Step 4: Subtract the result in the previous step from the first digit of the dividend (5-0 = 5) and write the answer below.
14 0
[tex]\sqrt{x}[/tex] 5
-0/5
pls help with these math problems
Answer:
Step-by-step explanation:
1)
First we add what we know for y into the second equation.
5x - 4(x +2)= -3
From there, we simplify it
5x-4x-8= -3
x-8=-3
Now we get the x on its own
x=5
and now we add x=5 into the first equation that we had and simplify to find y
y=5+2
y=7
So the answer is x=5, y=7 or (5,7)
2)
For this one we do the same thing as with 1.
Add what we know for y (bottom equation) to the top equation
3x-8(x-8)=24
Now we simplify
3x-8x+64=24
-5x+64=24
And now solve for X
-5x=-40
x=8
And then substitute x=8 to find y
y=8=8
y=0
So the answer is x=8, y=0 or (8,0)

-196,608
B.
-49,152
C.
-12,288
D.
-768
Answer:
D
Step-by-step explanation:
The value of 8th term of this sequence is,
⇒ a (8) = - 49,152
What is Geometric sequence?An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.
Given that;
Consider the first four terms of the sequence are,
⇒ -3, -12, -48, -192, . . .
Here, Common ratio is,
⇒ - 12 / - 3
⇒ 4
Thus, The sequence are in Geometric sequence.
Hence, The value of 8th term of this sequence is,
⇒ a (8) = - 3 × (4)⁸⁻¹
⇒ a (8) = - 3 × 4⁷
⇒ a (8) = - 3 × 16,384
⇒ a (8) = - 49,152
Thus, The value of 8th term of this sequence is,
⇒ a (8) = - 49,152

y=x²+2x+2
First, we should try to change the last number in a way so we can factor the entire thing
y=x² + 2 x + 1
tooo make it look like y=(x + 1 )²
the only difference between the original y=x² + 2x + 2
and the factor-able y=x² + 2x + 1 is simply changing the
2 to a 1 (Since we can't randomly change the 2 to a 1, we can add 1 and subtract a 1 to the equation at the same time to keep it balanced.)
