Answer:
Relative frequency of selecting a 2 = 8/50 = 0.16
Relative frequency of selecting a 3 = 14/50 = 0.28
Step-by-step explanation:
When we have a given experiment with given outcomes (such that each time that we perform the experiment, one outcome happens) the relative frequency of a given outcome is the quotient between the number of times that that outcome happened, and the total number of times that the experiment was performed.
Here the experiment is selecting a random number between 1 and 5, and it is performed 50 times.
Out of these 50 times, the outcome "2" appears 8 times.
Then the relative frequency of selecting the number 2 is:
f(2) = 8/50 = 0.16
And of these 50 experiments, the outcome "3" appears 14 times.
Then the relative frequency of selecting the number 3 is:
f(3) = 14/50 = 0.28
On a certain hot summer's day, 336 people used the public swimming pool. The daily prices are $1.50 for children and $2.50for adults. The receipts for admission totaled $613.00 How many children and how many adults swam at the public pool that day?
Let c represent the number of children ($1.75 each) and a represent the number of adults ($2.00 each).
We know that there were 340 people total, so c + a = 340. This implies that a = 340 - c
We also know that $1.75 c + $2.00 a = $609.25
By substituting a with 340 -c we have $1.75 c + $2.00 (340 -c) = $609.25
Use the distributive property to obtain $1.75 c + $680 - $2.00 c = $609.25
Subtract $680 from both sides and combine like terms to get - $0.25 c = - $70.75
Now, divide both sides by -$0.25 to get c = 283, the number of children.
The number of adults is 340 - c or 340 - 283 = 57
Answer:
227 children and 109 adults
Step-by-step explanation:
227*1.5+109*2.5=613
227+109=336
if x+1/x = 2 then x^3 + 1/x^3
Answer:
Let p (x) = x + 1 / x = 2
= x + 1 = 2x
= 2x - x = 1
or, x = 1.
let g(x) = x^3 + 1/x^3
since, x = 1
therefore,
g (1) = (1)^3 +1 / (1)^3
= 1 + 1 / 1
= 2 / 1
= 2
So, the answer to your question is 2.
x + 1 / x = 2
x × ( x + 1 / x ) = x × 2
x + 1 = 2x
x - x + 1 = 2x - x
x = 1
_________________________________
x^3 + 1 / x^3 =
1^3 + 1 / 1^3 =
1 + 1 / 1 =
2 / 1 =

Option D represents a data set with a lower quartile of 24 and an upper quartile of 42.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Quartiles are then selected as 3 points such that they create four groups in the data, each group approximately possessing 25% of the data.
The lower quartile, also called the first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.
Similarly, the second quartile (also called median) is approximately in mid of the data.
The third quartile has approx 75% in its left partition, and on its right lies approx 25% of the data.
Left to right is said in the assumption that data were arranged increasingly from left to right
Hence, the box plot that represents a data set with a lower quartile of 24 and an upper quartile of 42 from the given option is D.

find the surface area asap i’ll give brainliest
Answer:
The surface area of the prism is 544 in²
Step-by-step explanation:
Given;
base of the triangular prism, b = 12 in
side length, = 10 in and 14 in
height = 8 in
The surface area is calculated as follows;
S.A = 2(area of the triangular face) + area of the rectangualr faces
S.A = 2( ¹/₂ x 12 x 8) + 2(14 x 10) + 14 x 12
S.A = (96) + 2(140) + (168)
S.A = 96 + 280 + 168
S.A = 544 in²
Therefore, the surface area is 544 in²
plz help asap.. I have no idea how to do this.
Answer:
286
Step-by-step explanation:
Use term formula for +/-
Tn = a + (n-1)d
n= number of term
a= first number in sequence
d= difference between each number
T55 = 16 + (55-1)5
T55 = 16 + 270
=286
1 term= 5
10 terms = 50
16+ (55-1)5
16+54x5
54x5= 270
270+16=286
The 55th term would be 286

13.2 Area of Triangles
2. Find the area of the triangle.
14 ft
17 ft
Answer:
119
Step-by-step explanation:
Answer:
question 1 is, the area is 119
question two is, the base length is 18
Step-by-step explanation:
PART ONE
To figure this out we need to know that to find the area the equation is A=1/2bh so lets create our equation
A=1/2(17)(14)
A=1/2(238)
A=119
119 is your area
PART TWO
to find out the length we need to basically reverse what we did in the first part
270*2=540
540 divided by 30 (the height)=18
18 is the base length
to show it is correct we can use these numbers to find the answer
A=1/2(18)(30)
A=1/2(540)
A=270

Ana ganha 1200,00 reais em seu trabalho, se ela gastar um quinto em comida e dois terços do que sobrar em aluguel, quanto sobra, ou falta?
Answer:
Ana fica com a quantia de 560
Step-by-step explanation:
Dado
Ana ganha = 1200
Ela gasta um quinto com comida e dois terços do que resta com o aluguel
Valor que sobrou com Ana depois de gastar com comida e aluguel
1200 - 1/5 (1200) - 1/3 (1200)
1200 - 240 -400
1200 -640
560
Ana fica com a quantia de 560
What is 66.6% as a fraction ( simplest form )
what are the amplitude period phase shift and midline for F(x)=-4cos(3x-3.14)+2
Answer:
Step-by-step explanation:
f(x) = -4cos(3x-pi) +2
compare to f(x) = A cos (B(x+C))+D
A is amplitude =4
Period is 2pi/B so period = 2pi/3
Phase shift is C so phase shift = -pi (this could be positive if it shifted to the left)
Midline is at D so midline is y=2

A magazine collects these data measuring the battery life , in hours , of a sample of MP3 players : 5.7, 6, 6.1, 6.5, 6.8, 7.1, 7.4, 7.6, 8.1, 8.2 About how long does an MP3 player in the 50th percentile play ?
Answer:
the answer is 6.8
Step-by-step explanation:
The computation is shown below:
Since we have to determined the 50th percentile play
So,
= 50(nth value) ÷ number of observations
= 50(nth value) ÷ 10
= 5th value
= 6.8
Hence the answer is 6.8

Semicircles are constructed on the three sides of a triangle as shown below. Find the area of the shaded region.
Answer:
approximately 157 square units
Step-by-step explanation:
To find areas of all shaded regions, find the area of each of the three triangles
Area of circle with diameter of 6, radius of 3 is:
A = π3² = 9π
Area of circle with diameter of 8, radius of 4 is:
A = π4² = 16π
Area of circle with diameter of 10*, radius of 5 is:
A = π5² = 25π
*Found this value by using the Pythagorean Theorem for the right triangle
Total Area = 50π which is approximately 157 square units
Rishan is building a number 3091 using Place-value blocks. There are no thousands block. How many hundreds blocks can he use instead?
Given:
The number is 3091.
To find:
The number of hundreds blocks if there are no thousands block.
Solution:
The given number is 3091.
It can be written as:
[tex]3091=3000+0+90+1[/tex]
[tex]3091=3\times 1000+0\times 100+9\times 10+1\times 1[/tex]
[tex]3091=3\ Thousands+0\ Hundreds+90\ Tens+1\ Ones[/tex]
There are no thousands block. So,
[tex]3000=30\times 100[/tex]
[tex]3000=30\ Hundreds[/tex]
Therefore, the number of hundreds blocks in 3091 is 30.

What is the sum of interior angles of a 53-gon? Type just the number, no words, letters, or symbols
Answer:
S = 9180°
Step-by-step explanation:
Given the following data;
Number of sides = 53
To find the sum of interior angles of a 53-gon;
Mathematically, the sum of the interior angles in a regular polygon is given by the formula;
S = 180(n - 2)
Where;
n is the number of sides.
S is the sum of the interior angles
Substituting into the formula, we have;
S = 180(53 - 2)
S = 180 * 51
S = 9180°
