A single card is drawn at random from a standard 52 card deck. Work out the following probabilities in their simplest form: P(7) = P(not 7) =
Answer:
[tex]1) \frac{1}{13} \\ 2) \frac{12}{13} [/tex]
Step-by-step explanation:
to understand thisyou need to know about:simple probabilityPEMDAStips and formulas:there are 4 "7" cards in a decklet's solve:according to the question
P(7)=4/52P(7)=1/13according to the question
P(not 7)=1-[tex]\frac{1}{13}[/tex]P(not 7)=12/13Answer:
no of 7=4
total no of card =52
total not no.7=52-4=48
Step-by-step explanation:
probability of getting 7=4/52=1/13
probability of not getting 7=48/52=12/13
1. ∠XVR =
2. ∠RVS =
3. ∠WVS =
4. ∠RST =
5. ∠RSV =
6. ∠VSU =
7. ∠UST =
8. ∠TUS =
Answer/Step-by-step explanation:
1. ∠XVR = 180 - <XVW (angle on a straight line)
∠XVR = 180 - 55°
∠XVR = 125°
2. ∠RVS = <XVW (Vertical angles are congruent)
∠RVS = 55°
3. ∠WVS = ∠XVR (vertical angles are congruent)
∠WVS = 125°
4. ∠RST = <R + <RVS (exterior angle theorem)
<RST = 55 + 55
<RST = 110°
5. ∠RSV = 180 - (<R + <RVS) (sum of triangle)
∠RSV = 180 - (55 + 55)
∠RSV = 70°
6. ∠VSU = <RST (vertical angles are congruent)
<VSU = 70°
7. ∠UST = <RSV (vertical angles)
<UST = 70°
8. ∠TUS = 180 - (<UST + <T) (sum of triangle)
<TUS = 180 - (70 + 71)
<TUS = 39°
A regular hexagon is rotated in a counterclockwise direction about its center. Determine and state the minimum number of degrees in the rotation such that the hexagon will coincide with itself.
The minimum number of degrees in the rotation such that the hexagon will coincide with itself is 60°
What is hexagon?Hexagons are six-sided polygons in geometry. A hexagon is said to be a regular hexagon if all of its sides and angles have identical lengths. To put it another way, a regular hexagon's sides are congruent.
Given that, Around its center, a regular hexagon is rotated counterclockwise.
We are aware that a hexagon has six sides.
There are also 360 degrees.
According to the data given, the calculation is as follows:
= 360 /60
= 60 degrees.
Therefore, we may say that the rotation must be at least 60 degrees in total.

Here is a list of numbers.
32 29 30 37 34 33 31
Tanya thinks that to work out the median, she simply needs to find
the middle number. So she says that “37" is the median for this list of numbers.
Tanya's answer is not correct.
a) Describe what is wrong with her method.
b) Work out the median of the numbers in the list.
Answer:
a). To find the median from a set of numbers, you need to arrange them from ascending order (smallest to biggest), and then you need to find the number in the middle
b). 32
Step-by-step explanation:
b). Smallest to biggest
29, 30, 31, 32, 33, 34, 37
From the set of numbers given, we can clearly see that 32 is in the middle.
Which of the following is the maximum value of the function y = -x2 + 2x + 1?
We first complete the square.
y=-x^2+2x+1
y=-x^2+2x-1+1+1
y=-(x-1)^2+2
The maximum point is (1,2) since -1 in ( ) meant 1 unit to the right and +2 meant 2 units up.
The maximum point is (1,2) but the maximum value means the y value which is simply just 2.

Given that the random variable X = number of days a student sleeps in during the week, what is the correct notation for the probability that a student will sleep in at least 3 days?
Answer:
X > 3/7Step-by-step explanation:
X > 3/7
We know that the student sleeps in at least 3 days, but we don't know what the exact number is, we use an inequality where X is greater than or equal to 3 out of the 7 days.
1) You can spend at most $24 at the fair. Game
tickets cost $2 each, and ride tickets cost $4
each. You want to buy at least 3 game tickets
and more than 2 ride tickets. Write a system
of linear inequalities that represents the
situation. How many of each ticket can you
buy?
Answer:
2x+4y= 24
x≥3
y≤2
Step-by-step explanation:
Given data
total expenses= $24
let the number of tickets be x
and the number of rides be y
Tickets cost $2 each, and ride tickets cost $4
Hence the expression for the situation is given as
2x+4y= 24

In a school, 4 out of every 7 students are girls. if there are 84 students at the school, how many are boys. AND SHOW WORKING
Answer:36
Step-by-step explanation:
[tex]\frac{4}{7} =\frac{48\\}{84}[/tex]
for every 7 students there are 4 girls, so for every 84 there must be 48
7*12=84
4*12=48
so, in all 84 students there are 48 girls

to find the precentage of a fraction u have to try and make the bottom number 100, 1000, 10000 etc
to do that like the first 1 u do 2 x ? = 100 the answer is 50
Rule what u do to the bottom u have to do to the top
now that u multiply 50 down to make 100 u have to do as the rule say what u need to do is also multiply 1 to 50 to get the answer
as u might know that 100 mean % so u pet the top number and then %

Factorise x^2+11x+18
Answer:
(x + 9)(x + 2 )
Step-by-step explanation:
Sum =11
Product = 18
Factors = 9 , 2
When you multiply (9*2 = 18) and when you add (9 +2 = 11).
x² + 11x + 18 = x² + 9x + 2x + (9*2)
=x(x + 9) + 2(x + 9)
= (x + 9)(x + 2 )
Answer:
(x+9) (x+2)
Step-by-step explanation:
x^2+11x+18
x^2+9x+2x+18
x(x+9)+2(x+9)
(x+9) (x+2)

Hank's car travels 600 feet in 20 seconds. Andy's motorcycle travels 300 feet in 12 seconds. Which is faster, the car or the motorcycle? Explain your reasoning.
Answer:
the car travels faster
Step-by-step explanation:
Since the motorcycle has traveled 300 feet, and the car has traveled 600 feet, we will divide 600 by 2
600 divided by 2 = 300
Hank would have traveled 300 feet in 10 seconds
Andy traveled 300 feet at 12 seconds
Therefore Hanks car travels faster
Answer:
The car travels faster
Step-by-step explanation:
600 ft per 20 secs
How many feet in one sec?
600/20 = 30
Hank's car = 30 feet per second
300 feet in 12 sec
How many feet in one sec?
300/12 = 25
Andy's motorcycle = 25 feet per second

How do you find the height of a parallelogram without the area of it?
Answer:
See: https://brainly.in/question/12682555
Step-by-step explanation:
The link provided will take you to a differently worded explanation from another user.
You may see the "slant" referred to as a "hypoteneuse", as the shape created by the line of height(or altitude) is a right triangle. Given the base of the triangle and the "slant" or "hypoteneuse", format the equation (a²+b²=c²)-where a represents the height(altitude), b represents the base, and c represents the slant(hypoteneuse)- to fit your needs:
c²-b²=a². From this point, find the square root(√) of a. If it cannot be simplified further, then (√a) is your solution.
