Help! I don’t understand this
A game has two four-sides dice having the number 1, 6, 7, and 4 on their faces. Outcomes in the sample space are pairs such as (1,6) and (4,4).

d. what is the probability that the total showing is greater than 9?

I have the other ones solved but really need help on the last one.

There approximately 7133 books in the library;

Data;

To solve this problem, we simply need to use an equation to explain the word problem into mathematical statements.

Let the total number of books be represented by x

The number of fictional books = 3/4x

After 592 fictional books were donated;

[tex]\frac{3x}{4} + 592 = \frac{5}{6}x[/tex]

Let collect like terms and solve

[tex]\frac{3x}{4} +592 = \frac{5}{6} x\\\frac{5}{6}x - \frac{3x}{4} = 592\\ 0.083x=592\\x = 592/0.083\\x = 7132.53[/tex]

Answer:

mean: 14

median: 15

mode: 6, 15, 18

Step-by-step explanation:

For the mean, you add up all the numbers and divide by the number of numbers there are. There are 7 numbers here, so add and divide by 7.

For the median, you line the numbers up from least to greatest.

6, 6, 15, 15, 18, 18, 20

and find the middle number, which is 15.

For the mode, you have to find the number that repeats the most. For this set of numbers, it's 15, 18, and 6. Hope that helps!

Answer:

Mean  = 14

Median = 15

Mode = 6, 18, 15

Answer:

slope = - [tex]\frac{3}{11}[/tex]

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 14, 3 ) and (x₂, y₂ ) = (- 3, 0 )

m = [tex]\frac{0-3}{-3-(-14)}[/tex] = [tex]\frac{-3}{-3+14}[/tex] = - [tex]\frac{3}{11}[/tex]

Answer:

Step-by-step explanation:

f(x) = x⁴ - 8x² + 16

f'(x) = 4x³ - 16x = 4(x³ - 4x) = 4x(x² - 4) = 4x(x - 2)(x + 2)

f'(x) = 0, x = 2, -2

f"(x) = 4(3x² - 4)

f''(0) = -16 < 0, f""(2) = f''(-2) 3(12 - 4) > 0

so f(2) and f(-2) are minimum values

f(0) is maximum value.

f(0) = 16, f(2) = f(-2) = 2⁴ - 8*2² + 16 = 0

Maximum = 16, minimum value = 0

-∞ < x < -2, f'(x) < 0

-2 < x < 0, f'(x) > 0

0 < x < 2, f'(x) < 0

2 < x < ∞, f(x) > 0

increase: (-2, 0) and (2, ∞)

decrease: (-∞, -2) and (0, 2)

Answer:

$276

Step-by-step explanation:

in h.p he would pay 12*88= 1056

amount saved = 1056-780= 276

Freddy would save $276 if he buys the bike in a single payment instead of making 12 monthly payments of $88.

To calculate how much money Freddy will save by buying the bike in a single payment, we need to compare the total amount he would pay in each scenario.

If he makes 12 payments of $88, the total amount paid over the 12 months would be:

Total amount = 12 payments × $88 = $1056

If he makes a single payment of $780, that would be the total amount paid.

To calculate the savings, we subtract the total amount of the single payment from the total amount of the monthly payments:

Savings = Total amount of monthly payments - Total amount of single payment

Savings = $1056 - $780

Savings = $276

Step-by-step explanation:

A rational number that doesn't go on forever. Like Pi, that is not a rational number. But, 2.3 would be a rational number.

72/100 = .72 which is a rational number

Like I said before Pi goes on forever so it is NOT a rational number.

1 1/3. One is a rational number but 1/3 is o.3 with the 3 repeating forever. So it WOuld NOT be a rational number.

8/526 has numbers that go on forever so it would NOT be a rational number.

0.212212221 goes on forever. The three dots (...) signal that the decimal goes on. SO it would NOT be a rational number.

5/9= 0.555555555555555555555... the 5 goes on forever making it NOT a rational number.

Step-by-step explanation:

Shade 3/10 in the column then 9/10 in the row.

The answer is how much is cross shaded with both colors.

Here , we are given with a square which has 100 small squares in it , now we have to use two colours to represent 0.3 × 0.9 on it . So , now let's proceed :-

[tex]{:\implies \quad \sf \dfrac{3}{10}\times \dfrac{9}{10}}[/tex]

[tex]{:\implies \quad \sf \dfrac{27}{100}}[/tex]

Now , here , we have to colour 27 boxes with a colour and the left (100-27) = 73 boxes with another colour . Colour can be any of your choice

Explanation:

x = score on the fifth exam

The set {78,93,82,76,x} sums to 78+93+82+76+x = 329+x

Divide this over 5 since we have five total scores

(329+x)/5

That fraction represents the final average grade

Susan wants this average to be at least 85

[tex]\text{average} \ge 85\\\\\frac{329+x}{5} \ge 85\\\\329+x \ge 5*85\\\\329+x \ge 425\\\\x \ge 425-329\\\\x \ge 96\\\\[/tex]

Therefore, Susan must get a 96 or higher on the next exam if she wants to aim for the average to be 85 or larger.

In other words, the lowest grade she can get is a 96

The temperature after 22 minutes is 75.75 degrees

Given the resulting exponential model for the temperature, t, after m minutes can be approximated by the model t = 133(0.85)^m + 72.

If the time used is 22 minutes, the required temperature dring this time is expressed as:

t = 133(0.85)^22 + 72

t = 3.725 + 72

t = 75.75

Hence the temperature after 22 minutes is 75.75 degrees

Answer:

  P(B) = 0.20

Step-by-step explanation:

For these events, which are not independent or mutually exclusive, the relation between the various probabilities is ...

  P(A or B) = P(A) +P(B) -P(A and B)

Solving for P(B), we find ...

  P(B) = P(A or B) +P(A and B) -P(A)

  P(B) = 0.77 +0.13 -0.7 = 0.20

The probability of B is 0.20.

Additional comment

The formula applies to independent and mutually exclusive events, as well. For independent events, P(A and B) = P(A)·P(B). For mutually exclusive events, P(A and B) = 0.

Answer:

D

Step-by-step explanation:

if 15*5 is 75, than 75 is 5 times bigger than 15

The equation 15 × 5 = 75 represented the statement The number 75 is 5 times as many as 15, so option D is correct.

The equals sign is used in equations to indicate the equality of two expressions in a formula. It is a mathematical statement that says, "this is equivalent to that," in other words. There appears to be an equal sign in the middle, a mathematical expression on the right, and a mathematical expression on the left.

Given:

15 × 5 = 75

Assume the number is x = 5,

Here, you can see that x is 15 times to equal 75,

So, the above statement can be written as the number 75 is 5 times 15.

area = (1/4)*(2/3)

area = (1*2)/(4*3)

area = 2/12

area = 1/6 of a square inch

This confirms that choice A is a correct set of dimensions to lead to an area of 1/6 of a square inch.

Choice B leads to (1/3)*(1/3) = 1/9 which means we can rule it out.

Choice C leads to 1/36 and choice D leads to 1/24.
