Camilla makes and sells Jewelry. She has 8,160 silver beads and 2,880 black beads to make a necklace. Each necklace will contain 85 silver beads and 30 black beads. How many necklaces can she make?

The two angles form a right triangle which is 90 degrees.

Add the two to equal 90:

3x-8 + 4x = 90

simplify:

7x-8 = 90

Add 8 to both sides:

7x = 98

Divide both sides by 7:

x = 14

Answer:

You could pick as many as you like. Ideally you would use all the leaves on the tree, but that would be rather a large number to measure, and your parents might not be very happy if you stripped the tree bare!

So let's try 100 leaves.

How to get a random sample?

Here is one way you could get a random sample:

Try taking all the leaves on one branch of the tree. After you've discarded any that are broken, then see how many there are. If there are less than 100, then get the leaves from another branch until you have more than 100. Then write a different number (starting with 1) on each leaf with a marking pen.

Write the same numbers on small pieces of paper.

Fold the pieces of paper.

Put them into a hat and mix them up.

Draw 100 pieces of paper (without looking) from the hat. The first 100 pieces of paper you draw would give you the numbers of the leaves to use in the experiment.

The next thing you need to decide is how to measure the leaves, and

how accurate your measurements should be:

How to measure?

Keeping your leaves flat, use a ruler to measure the length of each leaf from the pointy part at one end of the leaf to the point where the leaf joins the stalk at the other end. Maybe your leaves bend a bit, but don't follow the main rib of the leaf as this would make measurement too difficult.

Just measure in a straight line as shown in the following diagram:

leaf

How accurate?

You should measure the length of each leaf to the nearest millimeter.

Now you're ready to begin.

Measure the length of each leaf to the nearest millimeter and record you results in a table, as follows:

Step-by-step explanation:

The probability for P(X<$400) is 0.7881.

The Z-score quantifies the discrepancy between a given value and the standard deviation. The Z-score, also known as the standard score, indicates how many standard deviations a specific data point deviates from the mean. In essence, standard deviation represents the degree of variability present in a given data collection.

Given:

Mean = $360

Standard Deviation = $50

We can use the z-score formula that is shown below:

Z = x - μ/σ

Where,

Z = standard score

x = observed value

μ = mean of the sample

σ = standard deviation

So,

z = 400 - $360/$50

z = 40/ 50

z= 0.8

and, P(x<400) = 0.78814

The survey results are most at risk for undercoverage.

A survey is the process research method in which a group of things are tested to find insights into the data collected from the groups.

As its mentioned in the question that the employees must respond to the questionnaire within five days.

The survey results are not at risk for non-response bias as its mandatory for every employee to respond to the survey results.

There can be a chance that the survey does not cover all the points that should be include in order to get employee satisfaction.

Therefore the survey results are most at risk for undercoverage.

Answer:

  -10f -6

Step-by-step explanation:

Maybe you want to simplify the expression ...

  3(-3f-2)-f

The distributive property is used to eliminate parentheses.

  = 3(-3f) +3(-2) -f

  = -9f -6 -f

Recognize like terms and group them together to make it easier.

  = -9f -f -6

Combine the like terms.

Answer:  4

===================================

Rule: The geometric mean of two numbers x and y is sqrt(x*y)

In this case, x = 2 and y = 8

So we have the geometric mean equal to sqrt(2*8) = sqrt(16) = 4

If you wanted to find the geometric mean of three values, then you'll multiply the numbers and take a cube root. If you had four values, then you multiply and apply a fourth root. And so on.

Answer:

822 × 5 + 2

Step-by-step explanation:

Given that:

4112 ÷ 5 = [tex]\frac{4112}{5}[/tex]

             = 822 remainder 2

To check if the answer is correct, we can write that;

[tex]\frac{4112}{5}[/tex] = 822 remainder 2

4112 = 5 x  822 remainder 2

       = 5 x  822 + 2

       = 822 x 5 + 2

4112 = 4112

Thus,the correct process of checking the answer is 822 x 5 + 2.

Answer:

D. No, because the given numbers do not satisfy the equation a² + b² = c²

Step-by-step explanation:

For the set of numbers; 24, 20, 32, to form a pythagorean triple, they must satisfy the equation a² + b² = c².

Where, c is the longest side (hypotenuse), while a and b are the two other legs.

Let's find out.

a = 20, b = 24, c = 32

Plug in the value into the equation

20² + 24² = 32²

976 = 1,024 (this is not true).

976 is not equal to 1,024.

The set of given numbers does not form a pythagorean triple because it does not satisfy the equation a² + b² = c².

Answer:

17abc

Step-by-step explanation:

To find the greatest common factor between 17abc and 51a²bc, let's start by breaking down any composite number here into prime factors. 17 is prime, but 51 is composite; its prime factorization is 3 · 17. Now, let's fully expand each term:

[tex]17\cdot a\cdot b\cdot c\\3\cdot17\cdot a\cdot a\cdot b\cdot c[/tex]

The greatest common factor is the product of all the factors these terms have in common. Here, we can see that they have

in common. Multiplying these together, the greatest common factor is 17abc.

Answer:

Step-by-step explanation:

Given the sequence

2, 8, 32, 128..

The sequence is a geometric sequence. The nth term of the geometric sequence is expressed as;

Tn = arⁿ⁻¹

a is the first term

r is the common ratio

n is the number of terms

From the sequence;

a = 2

r = 8/2 = 32/8 = 4

n = 11 (since we are to find the 11th sequence)

Substitute into the formula;

T₁₁ = 2(4)¹¹⁻¹

T₁₁ = 2(4)¹⁰

T₁₁ = 2(1,048,576)

T₁₁ = 2,097,152

Hence the 11th term of the sequence is 2,097,152
