The probability of having tails is 9/11

Data;

This is the possibility of an event occurring. In a sample space of 11 coin flips, tails came up 9 times and head came up 3 times

Number of time head came up = [tex]11-9 = 3[/tex]

The probability of having tails is calculated as

[tex]p = \frac{9}{11}[/tex]

The probability of having head is calculated as

[tex]p = \frac{3}{11}[/tex]

Answer:

Option B

Step-by-step explanation:

Given the following question:

In order to find the answer, we need to convert the scientific notation into standard notation and then simplify by subtracting the decimals. Then we convert the standard notation back into scientific notation.

[tex]0.0007 - (4.9\times 10^{-7} )[/tex]
[tex]4.9\times10^{-7} =0.00000049[/tex]
[tex]0.0007-0.00000049[/tex]
[tex]0.0007-0.00000049=0.00069951[/tex]
[tex]=0.00069951[/tex]
[tex]0.00069951=6.9951 \times10^{-7}[/tex]
[tex]=6.9951 \times10^{-7}[/tex]

Your answer is "6.9951 × 10^-7" or option B.

Answer:

10x+20y= 350

Step-by-step explanation:

Add the decimal. 3.50

Let's assume that all the coins are 10-cent coins.

The total value would be 10 x 40 = 400 cents = $4

So, it would be $2.5 less than the actual total value,

We now know that not all the coins are 10-cent coins, so now we will replace 1 10-cent coins with a 20-cent coins.

Everytime we switch a 1 10-cent coins to a 20-cent coins, the value go up 10 cents. So, we need to switch 25 times (to make the value goes up $2.5)

-> There are 25 20-cent coins and 15 10-cent coins

Recheck : 25 x 20 + 15 x 10 = 500 + 15 = 650 cents = $6.5

Answer:

12 units

Step-by-step explanation:

Applying the distance formula, [tex]\sqrt{(x_{2}- x_{1})^{2} + (y_{2}- y_{1})^{2} }[/tex], you get [tex]\sqrt{(2-2)^{2} +(4+8)^{2}}[/tex] = [tex]12[/tex] units.

B) [tex]\sf y=\left|x-3\right|[/tex]

Here in option B,

y-intercept:

y = |x-3|

y = |0-3|

y = 3

x-intercept:

0 = |x-3|

x - 3 = 0

x = 3

Thus option B is correct.

The amount of the annual withdrawals will be $16,574.24.The amount is the sum of the principal and the simple interest gain.

The complete repayment of money at the end of the time period for which it was borrowed is referred to as the amount.

The given data in the problem is;

P ia the annual payment

PV is the present value = $150,261

r is the rate of intreast = 9.1% = 0.091

n is the time period= 20

The formula for the annual payment is found as;

[tex]\rm P= \frac{r \times PV}{1-(1+r)^{-n}} \\\\ \rm P= \frac{0.091 \times 150261}{1-(1+0.091)^{-20}} \\\\ \rm P=16,754.2437[/tex]

Answer:

5a + ab = 40

Step-by-step explanation:

Sub in 10 for a, making the equation 5 x 10 + 10 x b

Then sub in - 1 for b making it 5 x 10 + 10 x - 1

Then multiply making it 50 + - 10

Then subtract since adding negative is actually subtracting and you get 40

Hey there!

In order to evaluate this expression, all we should do is plug in the values of the variables and simplify.

We are given that

a=10

b=-1

Plug in the values:

5(10)+(10)(-1)

multiply 5 times 10 and 10 times (-1) and add the products:

50+(-10)

or... actually subtract.

50-10

Option which does not help Olya to reduce her debt is to skip a month or two paying for her school loan and put the money towards her credit card debt.

Monthly payment is the payment which has to paid against the loan amount or the borrowed money calculated with interest rate.

Olya would like to find a way to reduce her current debt.  The table below shows Olya’s monthly income, expenses and net income.

Olya could spend less on entertainment each month and put the money towards her credit card payment. By this way she can pay the credit card payment faster.

Answer:

y = -3x + 7.

Step-by-step explanation:

First find the slope of the given line by converting to intercept form:

3x + y + 2 = 0

y = -3x - 2

So the slope is -3.

Then the line we want has a slope of -3 also (as it is parallel).

y - y1 = m(x - x1)   where m is the slope and (x1, y1) is a point on the line:

m = -3,  x1 = 1 and y1 = 4, so we have:

y - 4 = -3(x - 1)

y = -3x + 3 + 4

y = -3x + 7.

Using the normal distribution, it is found that 15.87% of the students received a score below 64.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given by, respectively: [tex]\mu = 70, \sigma = 6[/tex].

The proportion of students who received a score below 64 is the p-value of Z when X = 64, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{64 - 70}{6}[/tex]

[tex]Z = -1[/tex]

[tex]Z = -1[/tex] has a p-value of 0.1587.

Hence, 15.87% of the students received a score below 64.

Answer:

x = 6

Step-by-step explanation:

8(2x – 14) + 13 = 4x – 27

Lets go in the order of PEMDAS (Parantheses, Exponents, Multiplication, Division, Addition, Subtraction)

First, distribute 8.

8(2x – 14)

[tex]8*2x=16[/tex]

[tex]8*-14=-112[/tex]

So now our equation is:

16x – 112 + 13 = 4x – 27

Now we can add. We will add 13 to -112.

[tex]-112 +13=-99[/tex]

Now our equation looks like this:

16x – 99 = 4x – 27

Now we have to try to get the variable (x) on one side of the equation.

To do this, we will subtract 4x from both sides of the equation.

16x – 99 = 4x – 27

-4x            -4x

12x - 99 = -27

Now we can add 99 to -27.

[tex]99 + (-27) = 72[/tex]

Now we have

12x = 72

Our last step is to divide both sides by 12:

[tex]\frac{12x}{12}= \frac{72}{12}[/tex]

We get x = 6.

Answer:

Step-by-step explanation:

A.

8(2x – 14) + 13 = 4x – 27

Step 1: Distribute 8, meaning multiply 2x and -4 using 8

8(2x – 14)

8(2x) + 8(-14)

16x - 112

New equation:

16x - 112 + 13 = 4x – 27

Step 2: Add any numbers or like terms:

16x - 112 + 13 = 4x – 27

16x - 109 = 4x - 27

New equation:

16x - 99 = 4x - 27

Step 3: Isolate the variable on one side

16x - 99 = 4x - 27

-4x           -4x

12x - 99 = - 27

     + 99   + 99

12x = 72

Step 4: Divide both sides by 12

12x = 72

/12    /12

x = 6

B.

Check your answer:

8(2x – 14) + 13 = 4x – 27

8(2(6) - 14) + 13 = 4(6) - 27

8(12 - 14) + 13 = 4(6) - 27

8(-2) + 13 = 24 - 27

-16 + 13 = 24 - 27

-3 = -3

This statement is correct

Therefore, our answer (x = 6) is correct.
