PLEASE HELP!!!!!!A set of data includes 98 data points ranging from 0 – 160. If the data is split into classes with a range of 10 (1 – 10, 11 – 20, etc), and there are no values that fall in the class 81 – 90, what can you say about the data?
1 The mean of the data will not be between 81 – 90.
2 All the data lies below 80.
3 The relative frequency of the class 81 – 90 is 0.
4 The median could be in the range 81 – 90.
Zoey goes to a store an buys an item that costs x dollars. She has a coupon for 15% off, and then a 9% tax is added to the discounted price. Write an expression in terms of x that represents the total amount that Zoey paid at the register.
Answer:
0.9265x
Step-by-step explanation:
x - 0.15x + 0.09(0.85x)
x is the initial amount, -0.15x is subtracting 15% of the original amount (leaving 0.85x), and 0.09(0.85x) is the 9% tax.
Simplified:
x - 0.15x + 0.09(0.85x)
= 0.85x + 0.0765x
= 0.9265x

What is the value of x in this triangle? What is the value of each angle?
Answer:
x=17
Step-by-step explanation:
we know the 25 + 90 = 115 so we need the other one to make it 180 degrees.
180-115= 65
so we need 65 more degrees to get 180
now 3x + 11= 65 first step subtract 11 on both sides
you now get 3x = 54 then 2nd step is divide 3 on both sides
and now you get x=17 so
Answer:
Step-by-step explanation:
The entire value of the triangle is 180 degrees.
If you subtract 25 from 180 you are left with 155
Then Subtract 90 from 155 which will leave you with 65
Go on to subtract 11 from 65 having to be with 54 degrees left
Finally you will dived 54 by 3 and you are left with 18
3 x 18 = 54
54 + 11 = 65
Therefore x will equal to 65 degrees

A right triangle has a hypotenuse of 8 feet. One leg has a length of 5 feet. How long is the other leg?
A. 5 ft.
B. V39 ft
C. V89 ft
D. 13 ft.
Answer:
B
Step-by-step explanation:
The formula a^2 + b^2 = c^2 can be used to find any of the legs of the triangle. a and b are legs of the triangle and c is the hypotenuse. We can substitute known values into the equation:
a^2 + b^2 = c^2
One leg is 5 so we can put that in as a. And c, the hypotenuse, is 8.
5^2 + b^2 = 8^2
Now solve for b.
First, square 5 and 8
25 + b^2 = 64
Subtract 25 from both sides
b^2 = 39
Take the square root of both sides
b = √39

if a coin is flipped and a fair die is rolled 96 times, predict how many times you would flip a head and roll a 6
Answer:
Step-by-step explanation:
on flipping a coin, we either get a heads or a tails and both the events are equally likely. So the probablity of getting a tails is 1/2.
Now
On rolling a die, we can get 6 possible outcomes(1,2,3,4,5,6)
But the favourable outcomes (an even number) are only 3. So the probablity of getting an even number is 3/6=1/2
In case. we have 2 events that need to occur together, we simply need to multiply their individual probablities to get the probablity of getting both the events together
So our required answer is
p(even number)× p(tails)= 1/2 × 1/2 = 1/4

Solve for x.
−2/3(3x−4)+3x=5/6
x=−19/6
x=−11/6
x=21/6
x=29/6
Answer:
X = 11/6
Step-by-step explanation:
Answer:
b) x = -11/6
Step-by-step explanation:
Given equation,
→ (-2/3)(3x - 4) + 3x = 5/6
Now the value of x will be,
→ (-2/3)(3x - 4) + 3x = 5/6
→ (-6x + 8)/3 + 3x = 5/6
→ (-6x + 8 + 9x)/3 = 5/6
→ -6x + 8 + 9x = (5/6) × 3
→ 3x + 8 = 5/2
→ 3x = (5/2) - 8
→ x = (-11/2) × (1/3)
→ [ x = -11/6 ]
Hence, value of x is -11/6.

Find the value of the variable.
When you add all of these angles, the sum should be 180°. This helps us to figure out the value of the variable.
Now, you must create an equation.
3z+14+z+90=180
4z+14+90=180
4z+104=180
4z+104-104=180-104
4z=76
z=19
∴The value of the variable is 19.
To check:
3(19)+14+19+90
57+14+19+90
90+90
180
All of the angles together have a sum of 180 degrees, meaning that our value for the variable is indeed correct.
Hope this helps.
Answer:
z = 19
Step-by-step explanation:
These are complementary angles; both angles add up to 90°.
To solve this, we can combine like terms.
3z + (1)z + 14 = 90
3z + (1)z = 4z
**3z and z are the only pair of like terms.**
After combining like terms, we can proceed to solve this problem.
4z + 14 = 90.
Since there is an addition sign in front of 14, we do the opposite, subtraction.
First, subtract 14 from 90 and 14.
4z + 14 = 90
- 14 - 14
------------------
4z = 76
**ELIMINATE 14.**
Lastly, divide 76 from 4; this is because 4 is the coefficient.
4x = 76
76 ÷ 4 = 19
Therefore, z = 19.

Answer:
8 and 5 and 8 and 13
Step-by-step explanation:
Answer: I should measure first but I can not because it is an image but I leave you the explanation of how to do
Step-by-step explanation: Two angles are complementary if the sum of their degrees is equal to 90º (ninety degrees). For example: a 30º angle and a 60º angle are two complementary angles. Since 90º is the measure of a right angle, another way of saying that two angles are complementary is that together they form a right angle
