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

Answers

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

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

1 The mean of the data will not be between 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.

Answers

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

0.9265x is The answer hope it helps

What is the value of x in this triangle? What is the value of each angle?

Answers

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

Find the value of the variable.

Answers

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.

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.

Answers

Answer:

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

x=−19/6

x=−11/6

x=21/6

x=29/6

Answers

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.

What is the fewest number of people surveyed if exactly 93.6% of people completed a survey?
Use the whole numbers 0 through 9, at most one time, to fill in the boxes to create an accurate
number line.

Answers

Answer:

Step-by-step explanation:

the fewest number of people surveyed is 125, i’ll explain why.

the percentage of people that finished the survey is 93.6%, given.

this percentage as a fraction is p, (being the people) = 93.6/100, so, p = 93.6/100.

you then multiple the fraction 93.6/100 by 10, which is: p = 936/1000. then, reduce the fraction.

p = 117/125.

the fraction can’t be reduced any further, so that’s your answer.

A suit originally costing $240 is on sale for 25% off the original price. Sales tax is 7.5%. What is the final cost of the suit? (Math)

Answers

$193.50

start by multiplying 240 by .25 (25%) to find out how much is 25% of 240. this equals 60.
then, subtract $60 from $240. equals 180.
next, to add the sales tax, multiply 180 by 0.075 (7.5%) this is $13.50.
lastly, add the tax, which is $13.50, to the suit's sale price, which is $180.
180+13.5= $193.50
