Solving

7+3 × 24 ÷ 8 − (9 − 6 ÷ 3)2​

Answer:

96√3 cm^2

Step-by-step explanation:

half base = 4 cm

height of each triangle = 4√3 cm

Area of each triangle

(8 * 4√3)/2 = 16√3 cm^2

area of the hexagonal = 16√3 * 6 = 96√3 cm^2

Answer:

  A, 2

Step-by-step explanation:

In the factored form, the zeros are the values of x that make a factor zero. That is, one of the zeros is ...

  x -2 = 0   ⇒   x = 2

__

To find the zeros from the other forms, more work must be done. In the standard form, one of the usual solution methods must be used, possibly including putting the equation into factored form, completing the square, or using the quadratic formula. In vertex form, a root must be taken, then those values adjusted by translation to the axis of symmetry.

Answer:

5x = 11.

Step-by-step explanation:

-4x - 2y = -2

x    - 2y =  9  

Subtracting:

-4x - x - 2y - (-2y) = -2 - 9

-5x - 2y + 2y = -11

-5x = -11

5x = 11.

Answer:

Part A)

57.57 ; 5.757

Part B)

3% of 50 is 1.5.

300% of 50 is 150.

Together, they add to 151.5.

Step-by-step explanation:

To find something "of" something, we can multiply the two values.

A)

To find 101% of 57, we will multiply the two values. Hence:

[tex]101\%(57)=1.01(57)=57.57[/tex]

And 10% of that will be:

[tex]10\%(57.57)=0.1(57.57)=5.757[/tex]

B)

First, find 3% of 50:

[tex]3\%(50)=0.03(50)=1.5[/tex]

Next, we can find 300% of 50:

[tex]300\%(50) = 3(50)=150[/tex]

Finally, add:

[tex]\Rightarrow 1.5+150=151.5[/tex]

Step-by-step explanation:

get one card is 1/3 so you do 1/3x1/3x1/3

Answer:

75%

Step-by-step explanation:

List out known probabilities

[tex]\Pr(shirt) = 0.65 = \frac{65}{100} = \frac{13}{20}\\ \Pr(pants) = 0.40 = \frac{30}{100} = \frac{6}{20}\\\Pr(shirt \cap pants) = 0.20 = \frac{20}{100}=\frac{1}{5}[/tex]

recall equation

[tex]\Pr(A \cup B)=\Pr(A)+\Pr(B)-\Pr(A \cap B)[/tex]

Plug in values

[tex]\Pr(shirt \cup pants)=\frac{13}{20}+\frac{6}{20}-\frac{1}{5}\\\\therefore \Pr(shirt \cup pants) = \frac{15}{20} =\frac{3}{4} = 75\%[/tex]

Answer:

because in lowest term it's ratio is same

Step-by-step explanation:

hope you understand

Answer:

The ratios of 3:2, 6:4, and 9:6 are all equivalent because when you divide the numerator over the denominator, you get the same result for all of them. This means that if we took 3/2 and got 1.5, and took 6/4 and got 1.5 as an answer, and took 9/6 and got 1.5 as an answer as well, we would have the same answer for all of them. This is why (in my own words) the ratios are all equivalent.

Answer:

no solutions

Step-by-step explanation:

The lines are parallel and never intersect.  The solutions occur when the lines intersect, so there are no solutions

Answer:

  $55,811.91

Step-by-step explanation:

The amount with interest is given by the formula ...

  A = P(1 +r)^t

where r is the annual interest rate and t is the number of years.

  A = $25000(1.055^15) ≈ $55,811.91

The amount due at the end of 15 years will be $55,811.91.

Answer:

question 11 ans = $2.2

question 12 ans = 4

Answer:

{4, 4, 8, 13, 16}

Step-by-step explanation:

If we have a set of N numbers in order:

{x₁, x₂, ..., xₙ}

The median is the middle number of the set.

The mode is the value that is repeated more times in the set

The mean is computed as:

[tex]M = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]

And the range is the difference between the largest value and the smallest value.

Here we want 5 positive integers, so we have something like:

{x₁, x₂, x₃, x₄, x₅}

We know that the median is 8.

Then the middle value, x₃, is equal to 8.

We also know that the mode is 4, then we can have the number 4 repeated two times, and because 4 is smaller than 8 and this must be in order, then we can have:

x₁ = x₂ = 4

Replacing these in the set we have:

{4, 4, 8, x₄, x₅}

Now we know that the range is 12, and this was the difference between the largest and smallest value.

We know that the smallest value is 4, and the largest value is x₅, then we will have:

x₅ - 4 = 12

x₅ = 12 + 4 = 16

Then our set is:

{4, 4, 8, x₄, 16}

Finally, we know that the mean is 9.

Remember that the equation for the mean is:

[tex]M = \frac{4 + 4 + 8 + x_4 + 16}{5}[/tex]

Then we need to solve:

[tex]9 = \frac{4 + 4 + 8 + x_4 + 16}{5}[/tex]

[tex]9*5 = 4 + 4 + 8 + x_4 + 16}[/tex]

[tex]45 = 32 + x_4[/tex]

[tex]45 - 32 = x_4 = 13[/tex]

Then the set of five positive integers is:

{4, 4, 8, 13, 16}

Answer:

Answer:

c. normal probability distribution

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this question:

By the Central Limit Theorem, it is a normal distribution, so option c.

Step-by-step explanation:

The profit for selling x pairs of shoes is given by:

[tex]P(x)=-4x^2+32x-39[/tex]

And we want to determine the number of pairs that needs to be sold in order to maximize profit.

Since the function is a quadratic with a negative leading coefficient, the maximum profit will occur at its vertex point. The x-coordinate of the vertex of a quadratic is given by:

[tex]\displaystyle x=-\frac{b}{2a}[/tex]

In this case, a = -4, b = 32, and c = -39. Substitute and evaluate:

[tex]\displaystyle x=-\frac{(32)}{2(-4)}=\frac{32}{8}=4[/tex]

So, in order to maximize profit, only four pairs of sohoes should be sold.

Another alternative answer is "box-and-whisker plot"

The box portion consists of data between Q1 and Q3, with the median somewhere in between. The whiskers represent stuff below Q1 and above Q3. The tip of each whisker represents the min and max, assuming there are no outliers. If there are outliers, then you'll have island points disconnected from the main boxplot.

Answer:

y = ½x - 5

Step-by-step explanation:

Given the following data;

Slope, m = ½

Intercept, c = -5

To write the equation of straight line;

Equation of straight line is y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

Substituting the values into the formula, we have;

y = ½x + (-5)

y = ½x - 5

[tex] y = \frac {1}{2}x - 5 [/tex]
