median and the data 11 , 17 , 7 , 4 , 15 , 9
Answer:
10.
Step-by-step explanation:
median means the "middle" number in a set of numbers.
(I always the meaning of median by remembering "middle" because they rhyme).
NOTE: to find the median of a set of numbers you have to arrange that set of numbers in either ascending order (smallest to biggest value) or descending order (biggest to smallest value) .
sooo....
we were given :
11, 17, 7, 4, 15, 19
let's arrange in ascending order
4, 7, 11, 15, 17 , 19
now you can cancel them out ( cancel left number, right number)
i mean....
cancel out 4, cancel out 19
cancel out 7, cancel out 17
and we are left with 2 numbers which are11 and 15.
NOTE; (when you have two numbers or values remaining instead of one number, add those two numbers and divide by 2).
soooo...
11 + 15 = 20
20/2 = 10
median of the set of numbers is equal to 10.
Hope this helps.
Good luck ✅.

Find the surface area of the rectangular prism.
4 yd
3 yd
3 yd
Answer:
[tex]A = 66\ yd^2[/tex]
Step-by-step explanation:
You can either add up all the areas of the faces of the rectangular prism, or you can use the following formula:
[tex]A = 2(wl+hl+hw)\\A = 2(3 \times 3 + 4 \times 3 + 4 \times 3)\\A = 2(9+12+12)\\A = 2(33)\\A = 66[/tex]
Answer:
The surface area of the rectangular prism is [tex]66\ yd^2[/tex]
Step-by-step explanation:
Step 1: Find the area of the front and back
[tex]A = l * w[/tex]
[tex]A = 3\ yd * 4\ yd[/tex]
[tex]A = 12\ yd^2 * 2[/tex]
[tex]A = 24\ yd^2[/tex]
Step 2: Find the area of the top and bottom
[tex]A = l * w[/tex]
[tex]A = 3\ yd * 3\ yd[/tex]
[tex]A = 9\ yd^2 * 2[/tex]
[tex]A = 18\ yd^2[/tex]
Step 3: Find the area of the left and right sides
[tex]A = l * w[/tex]
[tex]A = 3\ yd * 4\ yd[/tex]
[tex]A = 12\ yd^2 * 2[/tex]
[tex]A = 24\ yd^2[/tex]
Step 4: Total area
[tex]A_{total} = 24\ yd^2 + 18\ yd^2 + 24\ yd^2[/tex]
[tex]A_{total}= 66\ yd^2[/tex]
Answer: The surface area of the rectangular prism is [tex]66\ yd^2[/tex]
Which of the following statements could be translated to the equation n - 5 = -2?
- A number less than five equals negative two.
- The difference between a number and five is negative two.
- If five is subtracted from a number, the result is two.
- Five less a number is equal to two.
please send help :')
Answer:
Answer would be B
Step-by-step explanation:
First, A doesnt make sense, since it isn't a ineqality.
C doesnt make sense because if 5 is subtracted form a number n, it is -2, not 2.
D doesnt work because 5 less a number (-5) is not 2, it is -2.
So B works, because the difference between n and 5 (n-5) is -2.

Answer:
1st option y-5 = 3(x-1)
Step-by-step explanation:
graph shows y intercept of 2
1st option has a y intercept of 2
Answer:
Option 1
Step-by-step explanation:
Clearly, the slope of the line is 3. (As it cannot be negative in this case and it's more vertical so it's not 1/3)
The point slope form is written as :
y - y₁ = m(x - x₁)
Substituting m = 3 :
y - y₁ = 3(x - x₁)
Option 1 is the only option with the value of m as 3.
What is the measure of E
Step-by-step explanation:
Represent D and E as x because you don't know them
Now the sum of all these angles is 180
so,D+E+90(THE SIGN AT THE TOP)=180
D which is x the E which is also x
x+x+90=180
2x+90=180
2x=180-90
2x=90
[tex] \frac{2x}{2} = \frac{90}{2} [/tex]
cancel and you will get x as 45
therefore x is 45 degrees

Convert 32.8% to a fraction in simplest form and a decimal.
Answer:
Step-by-step explanation:
32.8 = 164/5
= 32/4/5
as a fraction
To convert the decimal 32.8 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
32.8 = 32.8/1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,
32.8
1
= (32.8 × 10)
(1 × 10)
= 328/10
.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(328,10) = 2. So,
(328÷2)
(10÷2)
= 164/5
when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 328/ 10
is also equal to 32/4 /5
when expressed as a mixed number.

What is
-7+13+8X -2
Please help meee step by step
Answer:
-1/2 = x
OR
-0.5 = x
Step-by-step explanation:
1) Isolate x from the equation by making it equal to zero
(Reminder that everything crossing over to the other side of the equation changes it's symbols from positive to negative, and vice-versa is the original symbol was negative)
-7 + 13 + 8x - 2 = 0
-7 + 13 - 2 = -8x
2) Add up common terms on the left side
-9 + 13 = -8x
4 = -8x
3) Divide the entire equation by the number that would leave "x" by itself the factor or number that leaves the number by itself is negative eight since its the number with the equation (-8)
4/-8 = -8x/-8
-1/2 = x
OR
-0.5 = x
Hope this helps :)

Amos is painting his pots. He needs one forth of a liter to paint all four pots.
How much paint will he need for each of his 4 pots if he uses the same amount of paint on each?
Answer:
he would use 1/16 of a liter or 2.11 oz
Step-by-step explanation:
so i took 1/4 and divided up into 4 which is 1/16 and then i took 1/4 liter and divded that up into 4 to get 2.11 oz
Select the equation that matches the written description.
A number, y is eight less than negative nine times a number,x.
(А)
y = -4x + 8
B
y = 3x + 8
y = -9x - 8
D
y = 5x + 8
Answer:
C. y = -9x - 8
Step-by-step explanation:
Setting up the equation:
eight LESS (so minus sign before the 8) THAN (so 8 is being subtracted from the -9x) negative (-) nine TIMES (multiplication) a number, (variable) x.
We want to get the variable y alone, so this can be written as y = -9x - 8
In a card game, Alex has 2 diamonds 3 spades 4 clubs, and 1 heart. Without being able to see the cards wes is going to pick one of Alex's cards. What is the probability that wes will pick spade or a club
Answer:
4/10 or 40% chance he picks a spade and 3/10 or 30% he picks a club so in total he would have a 7/10 chance or 70% chance of getting spade or club
Step-by-step explanation:
The probability that Wes will pick a spade or a club from Alex's cards is 0.7 or 70%.
To find the probability that Wes will pick a spade or a club from Alex's cards, we need to determine the total number of spades and clubs in Alex's hand and divide it by the total number of cards.
Total number of spades = 3
Total number of clubs = 4
Total number of cards = 2 (diamonds) + 3 (spades) + 4 (clubs) + 1 (heart) = 10
Therefore, the probability that Wes will pick a spade or a club is:
(Picking spade or club) = (Total number of spades + Total number of clubs) / Total number of cards
= (3 + 4) / 10
= 7 / 10
= 0.7
So, the probability that Wes will pick a spade or a club from Alex's cards is 0.7 or 70%.

Mickey tosses a coin 50 times and records 27 heads. Based on these results, what is the probability if
Mickey tosses the same coin three more times, she will get three tails?
a) 112,833: 125,000
b) 23:50
c) 69:50
d) 12,167: 125,000
The probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.
What is probability of an event?It is the ratio in an event of the number of favorable outcome to the total number of outcome of that event.
As the probability of an event can not be more than the number 1. Thus, he probability of failure of a event is equal to the difference of the 1 to the success of the event.
Mickey tosses a coin 50 times and records 27 heads. Thus, the probability of getting a head is,
[tex]P=\dfrac{27}{50}\\[/tex]
The probability of not getting a head or getting a tail is,
[tex]P^{-1}=1-\dfrac{27}{50}\\P^{-1}=\dfrac{50-27}{50}\\P^{-1}=\dfrac{23}{50}[/tex]
Now, Mickey tosses the same coin three more times. The probability of getting three tails in these tosses are,
[tex]P_{3t}=\dfrac{23}{50}\times\dfrac{23}{50}\times\dfrac{23}{50}\\P_{3t}=\dfrac{12167}{125000}[/tex]
Thus, the probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.
