What is the value of z?

Answer:

The second graph

Step-by-step explanation:

The solution reads "x is greater than or equal to 11." The line under the > sign tells us that it's "greater than or equal to." "Greater than" tells us that the arrow will point to the right. "Or equal to" tells us that the circle over 11 will be closed. The second graph fits this criteria.

Answer:

Step-by-step explanation:

cot θ=11

tan θ=1/11

\(\sin ~2\theta=\frac{2 \tan ~\theta}{1+\tan^2 \theta} =\frac{2*\frac{1}{11} }{1+(\frac{1}{11} )^2}=\frac{22 }{122} \\\\cos~2 \theta=\frac{1-tan^2 \theta}{1+tan^2\theta} =\frac{1-(\frac{1}{11})^2 }{1+(\frac{1}{11} )^2} =\frac{120}{122} =\frac{60}{61} \\tan 2 \theta=\frac{2 tan\theta}{1-tan^2 \theta} =\frac{2*(\frac{1}{11 } )}{1-(\frac{1}{11} )^2} =\frac{2*11}{120} =\frac{11}{60}\)

Answer:

3/4 cup of coconut

Step-by-step explanation:

Given:

\(\frac{1}{2}\) cup of coconut for \(\frac{2}{3}\) cup of toothpaste

Required

Determine how much oil for a cup of toothpaste

Represent Coconut with C and Toothpaste with T;

So,

When

\(C = \frac{1}{2}\ \ T = \frac{2}{3}\)

We're to solve for

C when T = 1

This can be represented as:

\(\frac{1}{2} = \frac{2}{3}\) --- 1/2 to 2/3

\(C = 1\)

Cross Multiply:

\(C * \frac{2}{3} = \frac{1}{2} * 1\)

\(\frac{2}{3}C = \frac{1}{2}\)

Solve for C

\(C = \frac{1}{2}/\frac{2}{3}\)

\(C = \frac{1}{2}*\frac{3}{2}\)

\(C = \frac{3}{4}\)

This means Sean needs 3/4 cup of coconut oil

The Domain of the function is (-∞, -6) ⋃ (-3,∞)

The domain of a function is the set of all possible input values for which the function is defined. In other words, it is the set of values that the independent variable (usually denoted by x) can take on without causing the function to be undefined or produce an error.

For example, consider the function f(x) = 1/x. In this case, the function is undefined for x = 0, because division by zero is not allowed. Therefore, the domain of the function f(x) is all real numbers except for x = 0, which can be written as:

Domain of f(x) = {x ∈ ℝ : x ≠ 0}

d/a = -(11/12)

Step-by-step explanation:

a/(b+c+d)=4/3

3a = 4(b+c+d)    [Cross multiply]

3a = 4((b+c)+d)   [Note that b and c can be grouped as (b+c)]

---------------------

We can see the second equation also has a (b+c) group.  Isolate it to one side:

a/(b+c)=3/5

5a = 3(b+c)

(b+c) = (5a/3)

------------------

Now use this definition of (b+c) in the first equation:

3a = 4((b+c)+d)

3a = 4((5a/3)+d)   [Use the new value of (b+c), which is (5a/3)]

3a = 4(5a/3+3d/3)

3a = 4((5a + 3d)/3)

3a = (4/3)(5a + 3d)

3a = (20/3)a + 4d

9/3a = (20/3)a + 4d

-(11/3)a = 4d

4d = -(11/3)a

d = -(11/12)a

Rounding the result off to the nearest 10th, the lateral surface area of the cylinder is 822 inches².

Surface area is the total area of the exposed surfaces of a three-dimensional object. It is measured in square units such as square centimeters (cm2) or square meters (m2). Surface area is an important concept in mathematics, science, and engineering, as it is the total area that determines properties such as friction, heat transfer, and fluid dynamics. For example, a larger surface area can increase the rate of heat transfer and allow for more efficient cooling. Similarly, a larger surface area can increase the friction between two objects, allowing them to grip better. Surface area is also important in chemistry, as it affects the amount of gas or liquid that can be absorbed or released by a given object.

The cylinder has a radius of 11 inches and a height of 12.5 inches. To find the lateral surface area of a cylinder, the formula used is A = 2πrℎ, where r is the radius and h is the height of the cylinder. After plugging in the values, the lateral surface area of the cylinder is 821.75 inches². Rounding the result off to the nearest 10th, the lateral surface area of the cylinder is 822 inches².

Answer:

34 degrees

Step-by-step explanation:

If ABD = 64, and CBD is 30, we can use PWP( Part Whole Postulate)

Step 1.CBD + ABC = ABD

Step 2. Substitute

30 + ABC = 64

Step 3. Isolate ABC

34 = ABC

ABC is 34 degrees

9514 1404 393

Answer:

  34°

Step-by-step explanation:

It should be fairly intuitive that the two smaller angles add to give the value of the larger one. (Even if it's not, the angle sum theorem tells you this is true.)

  ∠ABC + ∠CBD = ∠ABD

  ∠ABC + 30° = 64°

  ∠ABC = 34° . . . . . . . . . subtract 30° from both sides of the equation

:According to the question:You are working with a population of crickets. Before the mating season you check to make sure that the population is in Hardy-Weinberg equilibrium, and you find that the population is in equilibrium.

During the mating season you observe that individuals in the population will only mate with others of the same genotype (for example Dd individuals will only mate with Dd individuals). There are only two alleles at this locus ( D is dominant, d is recessive), and you have determined the frequency of the D allele =0.6 in this population. Selection acts against homozygous dominant individuals and their survivorship per generation is 80%. After one generation the frequency of DD individuals will decrease in the population.

According to the Hardy-Weinberg equilibrium equation p² + 2pq + q² = 1, the frequency of D (p) and d (q) alleles are:p + q = 1Thus, the frequency of q is 0.4. Here are the calculations for the Hardy-Weinberg equilibrium:p² + 2pq + q² = 1(0.6)² + 2(0.6)(0.4) + (0.4)² = 1After simplifying, it becomes:0.36 + 0.48 + 0.16 = 1This means that the population is in Hardy-Weinberg equilibrium. This is confirmed as the frequencies of DD, Dd, and dd genotypes

        \(\displaystyle \frac{3/8\;of\;the\;distance}{9\;min} =\frac{8/8\;of\;the\;distance}{x\;min}\)

Next, we will cross-multiply.

        3/8 * x = 8/8 * 9

        \(\frac{3}{8}\)x = 9

Inequality: 0.08x + 2300 ≥ 2800

Liz needs to sell products of $6250 at least.

Step-by-step explanation:

Given that:

Per month salary of Liz = $2300

Commission = 8% = \(\frac{8}{100}}\) = 0.08

Amount Liz wants to earn = $2800

Let,

x be the amount of sales.

0.08x + 2300 ≥ 2800

0.08x ≥ 2800 - 2300

0.08x ≥ 500

Dividing both sides by 0.08

\(\frac{0.08x}{0.08}\geq \frac{500}{0.08}\\x\geq 6250\)

Hence,

Liz needs to sell products of $6250 at least.

To determine the probability that testing positive means Roberto has Condition A, we need to use Bayes' theorem.

Let's define the following probabilities:

A: Roberto has Condition A

B: Roberto tests positive

According to the information given, the probability of having Condition A is 1 out of every 1000 people (0.1%), so P(A) = 0.001.

The test is stated to be 99% accurate, which means the probability of testing positive when someone has Condition A is 99%, so P(B|A) = 0.99.

The test's accuracy is also defined as the complement of the false positive rate, meaning the probability of testing negative when someone does not have Condition A is also 99%.

Therefore, P(~B|~A) = 0.99.

Using Bayes' theorem, we can calculate the probability that Roberto has Condition A given that he tested positive:

P(A|B) = (P(B|A) * P(A)) / P(B)

The denominator P(B) can be calculated as the sum of two possibilities: testing positive when having Condition A (true positive) and testing positive when not having Condition A (false positive).

P(B) = P(B|A) * P(A) + P(B|~A) * P(~A)

= 0.99 * 0.001 + (1 - P(~B|~A)) * (1 - P(A))

= 0.99 * 0.001 + (1 - 0.99) * (1 - 0.001)

= 0.00099 + 0.00999

= 0.01098

Substituting the values back into Bayes' theorem:

P(A|B) = (0.99 * 0.001) / 0.01098

= 0.00099 / 0.01098

≈ 0.09016

Therefore, the probability that testing positive means Roberto has Condition A is approximately 9.02%, which is closest to 9%.

Please check the format of the equation in the question.

Step-by-step explanation:

7x (5-98) ^4 = x +2

I will assume that the x in "7x" is the variable x, and not the multiplication sign.  The expression (5-98)^4 is a bit odd, so please check.  I'll assume it is correct.

7x (5-98) ^4 = x +2

7x (-93) ^4 = x +2

7x (74805201) = x +2

523636407x = x+2

523636406x = 2

x = 2/(523636406)

This seems to be an extraordinarily odd number, but that's the solution to
