Answer:
[tex]\frac{11}{25}[/tex]
Step-by-step explanation:
In the experiment that was conducted the coin was tossed a total of 75 times and out of those times it only landed on tails 33 times. Therefore the experimental probability of the coin landing on tails can be calculated by the dividing the times it landed on tails by the total number of times it was tossed. Like so...
[tex]\frac{33}{75}[/tex] or 0.44
This fraction can also be simplified to its simplest form of [tex]\frac{11}{25}[/tex] which is obtained by dividing both the numerator and denominator by 3

Answer:
4
Step-by-step explanation:
so 8*6=48, so we know that (4*6)+(_*6) should equal 48.
4*6=24
subtract 24 by 48 and we get 24.
now you probably know that it equals 4, but to be sure, divide 24 by 6, and you'll get 4.
Answer:
From top to bottom:
1st box: 4
2nd box: 24
3rd box: 48
Step-by-step explanation:
So, based on my knowledge, you are learning the Distributive probability. So, what the Distributive property does is it basically allows to distribute the one of the numbers in the multiplication problem. In this problem, we can see that the 8 is being distributed into two groups of 4 to make (4 * 6) + (4 * 6). Then, we solve the things in the two parenthesis, making 24 + 24. Now, all we have to do is add 24 + 24, making 48.
2. 252 - 200 – 8 x 5 = 247
Insert parenthesis to make the answer true

Step-by-step explanation:
Power is the result of multiplying two numbers together. The correct option is 2×2×2×2×2×2, 4×16, and 8×8.
What is power?Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
The given expression can be written as,
2⁶ = 2 × 2 × 2 × 2 × 2 × 2
= 4 × 16
= 8 × 8
Hence, the correct option are 2×2×2×2×2×2, 4×16, and 8×8.

a) 25.8
b) 36.8
c) 64.2
d) 42.0
Answer:
y = 25.8
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos y = adjacent/ hypotenuse
cos y = 18/20
Take the inverse cos of each side
cos ^-1 (cos y) = cos^-1(18/20)
y =25.84193276
Rounding to the nearest tenth
y = 25.8
If 1/4 gallons of water are enough to fill 7/10 of the pool how much water is nessacary to fill in the entire pool
============================================================
Work Shown:
1/4 = 0.25
7/10 = 0.70 = 70%
We are told that 0.25 gallons of water fills 70% of the pool
We want to find how many gallons of water (call it x) are needed to fill 100% of the pool.
Set up the proportion below and solve for x
(0.25 gallons)/(70% filled) = (x gallons)/(100% filled)
0.25/70 = x/100
0.25*100 = 70x ....... cross multiply
25 = 70x
70x = 25
x = 25/70
x = (5*5)/(5*14)
x = 5/14 gallons
----------------------------------------
An alternate method:
1/4 gallons = 7/10 pools filled
(10/7)*(1/4 gallons) = (10/7)*(7/10 pools filled)
(10*1)/(7*4) gallons = (10*7)/(7*10) pools filled
10/28 gallons = 1 pool filled
(5*2)/(14*2) gallons = 1 pool filled
5/14 gallons = 1 pool filled
In the second step, I multiplied both sides by 10/7 so that the "7/10" turns into "1".
----------------------------------------
Yet another alternate method:
1/4 = 10/40
7/10 = 28/40
We need 10/40 gallons of water to fill 28/40 of one pool. We can multiply both fractions by 40 to indicate that 10 gallons of water will fill up 28 pools.
So we have this ratio
10 gallons : 28 pools
Dividing both parts by 28 tells us how many gallons are needed for one pool
10 gallons : 28 pools
10/28 gallons : 28/28 pools
10/28 gallons : 1 pool
5/14 gallons : 1 pool

$77 at 16% for 6 months
What is the difference between the total amount in the account if you did simple and compound interest?
Answer:
$0.231
Step-by-step explanation:
Given data
P= $77
r= 16%
t= 6 months= 0.5 years
For simple interest
A= P(1+rt)
A=77(1+0.16*0.5)
A= 77(1+0.08)
A= 77*1.08
A= $83.16
For compound interest
A=P(1+r)^t
A= 77(1+0.16)^0.5
A= 77(1.16)^0.5
A= 77*1.077
A= $82.929
The difference is
=83.16- 82.929
=$0.231

Formula of area
AREA = LENGTH (multiply) BREATH
Answer:
The area of a triangle can be calculated with the formula: 1/2(bh), where b is the base length, and h is the height.
In this case, 4 is the base, and 7 is the height.
So we have: Area = 1/2(4)(7)
Simplifying: Area = 2(7), Area = 14.
The area of the triangle is 14 meters squared.

Choose the missing step in the given solution to the inequality −2x − 14 > −4 + 3x.
−2x − 14 > −4 + 3x
−5x − 14 > −4
_____________
x < −2
A. −5x < 10
B. −5x > −18
C. −5x > 18
D. −5x > 10
Answer:
Step-by-step explanation:
-2x - 14 > -4 + 3x
subtract 3x from both sides
-5x - 14 > -4
add 14 to both sides
-5x > 10
divide both sides by -5
x < -2
The answer would be -5x > 10.
This is because our last inequality was -5x - 14 > -4 so we add 14 to both sides and it would look like this -5x (-14 + 14) > (-4 + 14) which would transition into our next inequality -5x > 10.
So therefore the answer would be -5x > 10.

Answer:
Euler's formula for polyhedron is:

Answer:
1) Zero based on (-16·t - 2) is t = -1/8 second
2) Zero based on (t - 1) is t = 1 second
Step-by-step explanation:
The given functions representing the height of the beach ball the child throws as a function of time are;
y = (-16·t - 2)·(t - 1) and y = -16·t² + 14·t + 2
We note that (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
Therefore, the function representing the height of the beachball, 'y', is y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The zeros of a function are the values of the variables, 'x', of the function that makes the value of the function, f(x), equal to zero
In the function of the question, we have;
y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The above equation can be written as follows;
y = (-16·t - 2) × (t - 1)
Therefore, 'y' equals zero when either (-16·t - 2) = 0 or (t - 1) = 0
1) The zero based on (-16·t - 2) = 0, is given as follows;
(-16·t - 2) = 0
∴ t = 2/(-16) = -1/8
t = -1/8 second
The zero based on (-16·t - 2) is t = -1/8 second
2) The zero based on (t - 1) = 0, is given as follows;
(t - 1) = 0
∴ t = 1 second
The zero based on (t - 1) is t = 1 second
