What is the probability of a face with less than 5 spots turning up when you toss a die?
answer correctly and please explain
Answer:
2/3
Step-by-step explanation:
Probability =
= No. of faces having less than 5 spots / Total no. of faces
= 4/6
=2/3
The probability of a face with less than 5 spots turning up when it tosses a die which has 6 total outcomes is 2/3 or 0.667.
What is probability of an event?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
The probability of a face with less than 5 spots turning up when a die is tossed has to be find out.
Here, in this die, it is known that,
The number of total outcome is 6 {1,2,3,4,5,6}The number of favorable outcome to be a face with less than 5 spots is 4 {1,2,3,4}.Thus, the probability of this event is,
[tex]P=\dfrac{4}{6}\\P=\dfrac{2}{3}\\P=0.667[/tex]
Thus, the probability of a face with less than 5 spots turning up when it tosses a die which has 6 total outcomes is 2/3 or 0.667.

what is the circumference of a circle with a radius of 16mm
Answer:
100.48
Step-by-step explanation:
π = 3.14
C = circumference
To find the circumference for a circle you must do 2 times pie times the radius.
(2·π·16)
In this case the radius is 16.
2·π = 6.28
6.28 · 16 = 100.48

A. $125.00

D. $250.00
A. $125.00
B. $62.50
C. $31.25
D. $250.00
Answer:
Answer = C.31.25
Step-by-step explanation:
SO there are 4 years and every year the price gets 50% of so we take it as 100/2 = 50% so we have to divide 500 by 2 four times that is -
1. 500/2 ( 50% of 500) = 250
2. 250/2 (50% of 250) = 125
3. 125/2 (50% of 125) = 62.50
4. 62.50/2 (50% of 62.50) = 32.25
so we divided 500 4 times to get the answer as 32.25$

2y^2/6 + 5/7 + y/4.
I’m thinking it is 1 or 4 but cannot come to a conclusion, and there is nothing on the internet for this
Thank you.
Answer:
is it written like this?
if so then the coefficient of y is 1
Answer:
¼
Step-by-step explanation:
A coefficient is the number that comes before a variable, including its sign (plus/minus). Thus, the coefficient of y is the number that comes before the variable y.
[tex] \frac{y}{4} [/tex] can also be written as [tex] \frac{1}{4} y[/tex]. Since the sign before ¼ is a plus sign, the coefficient of y can simply be written as ¼.

Aregular hexagon is dilated by a scale factor of 0.4 to create a new hexagon. The perimeter of the new hexagon is 0.4 times the perimeter of
the original hexagon
O True
False
Answer:
True.
Step-by-step explanation:
It is given that, a regular hexagon is dilated by a scale factor of 0.4 to make image.
It means, the perimeter of image is 0.4 times the perimeter of the original hexagon.
For example,
Let's take the rectangle with length of 12 and width of 4, it's perimeter is 12+12+4+4 =32
Let's find image using scale factor 0.4, we get
length =0.4(12)= 4.8
width =0.4(4)=1.6
So, perimeter of image = 4.8+4.8+1.6+1.6=12.8
If we compare the perimeters
0.4(32)=12.8.
So, it is true.

IF Triangle DEF JKL, find KL.
Answer:
b
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{KL}{EF}[/tex] = [tex]\frac{JK}{DE}[/tex] , substitute values
[tex]\frac{6x+3}{x+11}[/tex] = [tex]\frac{25}{10}[/tex] ( cross- multiply )
10(6x + 3) = 25(x + 11) ← distribute parenthesis on both sides
60x + 30 = 25x + 275 ( subtract 25x from both sides )
35x + 30 = 275 ( subtract 30 from both sides )
35x = 245 ( divide both sides by 35 )
x = 7
Then
KL = 6x + 3 = 6(7) + 3 = 42 + 3 = 45 → b

what is the slope?
Answer:
26 min
Step-by-step explanation:
The slope of the data will be equal to 2 for the book reading.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is also defined as the ratio of the rise to the run of the line.
Given that Jenny started reading her book for English class at 8:03 p.m. and she started on page 24. At 8:29 p.m., Jenny stopped reading and was on page 37.
The slope of the data will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 29 - 3) / ( 37 - 24)
Slope = 2
Therefore, the slope of the data will be equal to 2 for the book reading.

Answer:
x = 16
y = 16√3
Step-by-step explanation:
sin(30 degrees) = 1/2
x = 32/2 = 16
cos(30 degrees) = √3/2
y = 16√3
Answer:
x = 16
y = 27.7
Step-by-step explanation:
solving for x: use sine
sine = [tex]\frac{opposite}{hypotenuse}[/tex]
⇒ sine 30 = [tex]\frac{x}{32}[/tex]
sine of 30 is 0.50
⇒ 0.50 = [tex]\frac{x}{32}[/tex]
multiply 32 on both sides:
⇒ 0.50 x 32 = [tex]\frac{x}{32}[/tex] x 32
solve:
⇒ 16 = x
solving for y: use cosine
cosine = [tex]\frac{adajcent}{hypotenuse}[/tex]
⇒ cosine 30 = [tex]\frac{y}{32}[/tex]
cosine of 30 is 0.866
⇒ 0.866 = [tex]\frac{y}{32}[/tex]
multiply 32 on both sides
⇒ 0.866 x 32 = [tex]\frac{y}{32}[/tex] x 32
solve:
⇒ 27.7 = y

Answer: 1430 girls
Step-by-step explanation:
In order to solve this we must take it step by step. So first things first. There are 12,481 people at this concert. If 8906 are adults we need to subtract to find out how many children there are. 12481-8906=3575. There are 3,575 children at this concert. Now if 3/5 of the children are boys then the other missing 2/5 must be the girls. There are a couple of ways to solve this but im going to go the direct route. multiply 3/5 by 3,575 to get 2,145 boys. Now if 2,145 out of 3,575 are boys then 3575-2145= 1430 girls
Let's sum up what we learned
1. 12,481 people are at a concert
2. 8906 adults are at this concert
3. 3,575 are children
4. 2145 are boys
5. Which means there are 1430 girls
