Answer:

-79.78 (really stinking cold)

Step-by-step explanation:

Solving the equation will go like this:

5/9(F - 32) = -62.1

multiply both sides by 9 to get rid of the fraction

5 (F - 32) = -558.9

divide both sides by 5

F - 32 = -111.78

add 32 to both sides

F = -79.78

Answer:

0.0017 years

Step-by-step explanation:

Distance of North Star from Earth = 460 light years

A light year is the distance traveled by light in one year.

As per given statement:

Distance traveled by light in one second = 18600 miles

Distance traveled by light in one year (\(60 \times 60 \times 24\times 365\)) = 18600 \(\times\) 31536000 miles = 14506560000 = 14.51 \(\times\) \(10^9\) miles

We know that:

1 billion = \(10^9\)

Therefore, 14.51 \(\times\) \(10^9\) miles = 14.51 billion miles

Also, it is given that speed of rocket = 1 billion miles per hour

Formula to represent relationship between Speed, Distance and Time is given as:

\(Distance = Speed \times Time\)

\(Time = \dfrac{Distance}{Speed}\)

\(Time =\dfrac{14.51\ billion\ miles}{1\ billion\ per\ hour}\\\Rightarrow Time = 14.51\ hours\)

If your friend went to bed at 1:00am on Friday and woke up at 1:00pm on Friday, she slept for 12 hours.

To see why, you can count the number of hours between 1:00am and 1:00pm:

1:00am to 2:00am = 1 hour

2:00am to 3:00am = 1 hour

...

11:00am to 12:00pm = 1 hour

12:00pm to 1:00pm = 1 hour

The total number of hours between 1:00am and 1:00pm is 12 hours.

To begin solving this problem, we need to determine the dimensions of the rectangular region that the farmer will fence in. Let's say the length of thr uses, is given by the equation:
e rectangle is L and the width is W. The perimeter of the rectangle, which will be the length of fencing the farme
2L + W = 350

Solving for W, we get:

W = 350 - 2L

Next, we need to divide the rectangular region into three smaller rectangles by placing two parallel fences. Let's say the two fences are placed along the length of the rectangle, dividing it into three sections with widths of x, y, and z. Therefore, we have:

L = x + y + z

Now, we can determine the area of the entire fenced-in region by summing the areas of the three smaller rectangles. The area of a rectangle is given by the equation:

Area = Length x Width

Therefore, the total area of the fenced-in region is:

Area = (xW) + (yW) + (zW)

Substituting W = 350 - 2L and L = x + y + z, we get:

Area = (x(350-2(x+y+z))) + (y(350-2(x+y+z))) + (z(350-2(x+y+z)))

Simplifying this equation, we get:

Area = 350(x+y+z) - 2(x^2 + y^2 + z^2)

To maximize the area, we need to take the derivative of this equation with respect to one of the variables (x, y, or z), set it equal to zero, and solve for the variable. This process is too complicated to do by hand, so we will use a calculator or computer program to find the maximum area.

After finding the maximum area, we can determine the dimensions of the region that give us this maximum area. We do this by using the equations we derived earlier:

W = 350 - 2L

L = x + y + z

With the maximum area and these equations, we can solve for the dimensions of the region that give us the maximum area.

In summary, the farmer should fence in a rectangular region with dimensions that maximize the total area of three smaller rectangles created by placing two parallel fences. The maximum area can be found by taking the derivative of the area equation and setting it equal to zero. The dimensions of the region that give us the maximum area can be found by using the equations we derived earlier.

So the answer is: the first arc should pass through point B (not A). All other elements in the diagram appear to be correct.

The elements or members of a set are the parts that make it up. To divide the components of a set, commas and two curly (idle) braces are typically employed. Capital letters are always used to print the set's name. The set "A" in this context consists of the letters v, w, x, y, and z.

Based on the given diagram and instructions, it appears that the error in the construction is that the first arc is centered at point C instead of point A. The correct procedure for constructing a line parallel to line AB and passing through point P is as follows:

1.Draw a line AB and mark point P not on line AB.

2.From point P, draw an arc that intersects line AB at points D and E.

3.Draw another arc, centered at point D, with the same radius as the first arc. This arc should intersect the first arc at point F.

4.Draw a line through point P and point F. This line is parallel to line AB and passes through point P.

By approving the drug, the FDA has accepted the alternative hypothesis that the drug is effective. Therefore, a Type I error (rejecting the null hypothesis when it is actually true) could not have been made.

If the FDA approves the drug, it means they have accepted the alternative hypothesis that the drug is effective, and therefore, a Type I error (rejecting the null hypothesis when it is actually true) could not have been made.

In hypothesis testing, a Type I error occurs when we reject the null hypothesis even though it is true. This means we falsely conclude that there is an effect or relationship when there isn't one. In the context of drug approval, a Type I error would mean approving a drug that is actually ineffective or potentially harmful.

By approving the drug, the FDA is essentially stating that they have sufficient evidence to support the effectiveness of the drug, indicating that a Type I error has been minimized or avoided. However, it is still possible to make a Type II error (failing to reject the null hypothesis when it is actually false) by failing to approve a drug that is actually effective.

Step-by-step explanation:

Answer:

80 degrees

Step-by-step explanation:

The 132-deg angle is an exterior angle of the left triangle.

The 52-deg angle is a remote interior angle to the exterior angle above.

Angle VZY is also a remote interior angle to the exterior angle above.

Theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of its two remote interior angles.

We use the theorem above to find the measure of angle VZY.

52 + m<VZY = 132

m<VZY = 80

Angles WZX and VZY are vertical angles, so they are congruent.

m<WZX = m<VZY = 80

Answer: 80 degrees

Answer:

m∠WZX = 80°

Step-by-step explanation:

Angle V is a flat angle, so it measures 180°.

Find ∠YVZ (blue angle): 180° - 132° = 48°

Triangle VYZ is 180° (all triangles are 180°).

Find ∠YZV (red angle): 180° - 52° - 48° = 80°

Since you know ∠YZV, you can find ∠WZX (green angle).

∠YZV and ∠WZX are opposite angles, so they are congruent.

Therefore, ∠WZX = 80°

Answer: 58°

Step-by-step explanation:

They say the triangles are equal. And they give us more information for the triangle on the right.

∠E = ∠B

We know ∠C and ∠D, so you should add them all up to equal 180. (degree of a triangle)

74 + 48 + ∠E = 180

122 + ∠E = 180

∠E = 58

So therefore ∠B = 58

Answer:

x = 29

Step-by-step explanation:

Focus on ΔDEC first. We know that two of its angles are ∠C = 48° and ∠D = 74°.

All of a triangle's angles must add up to 180° by the Triangle Sum Theorem. 48° + 74° = 122°. 180° - 122° is 58°. So ∠E is 58°.

Because the triangles are congruent, ∠E corresponds to ∠B.

Because ∠B is "2x," divide 58° by 2. 58° ÷ 2 = 29°. 29° × 2 = 58°, so this checks out.

The exponential equation after solving gives -26.

Exponential equations are equations where the independent variable, x is in the exponent.

The given equation is,

\(5^{7x+5}\) = \(125^{2x-7}\)

We know that 125 = 5³

\(5^{7x+5}\) = \(5^{3(2x-7)}\)

The base in the both sides of the equation is 5.

So,

7x + 5 = 3(2x - 7)

7x + 5 = 6x - 21

7x - 6x = -21 - 5

x = -26

The probability of getting three of the same symbol in a row depends on the specific rules of the slot machine and the distribution of symbols on the reels.

To determine the probability of getting three of the same symbol in a row, we need to know the total number of possible outcomes and the number of favorable outcomes. The total number of possible outcomes is determined by the number of symbols available on each reel and the number of reels.

For example, if there are three reels and each reel has six different symbols, then the total number of possible outcomes is \(6^3\)= 216.

To calculate the number of favorable outcomes, we need to consider the specific combination of symbols that result in three of the same symbol in a row. Without knowing the specific distribution of symbols on the reels or any specific rules of the slot machine (such as the presence of wild symbols or special features), it is not possible to determine the number of favorable outcomes.

Factor when dividing the function the remainder is zero. The factorized form of the function \(f(x)=-3x^2+6x-9\) is -3(x²-2x+3).

A factor of a function is a factor which when multiplied by another the result is the function itself.

We know that in order to factorize a function of the second-order, we need to take the common terms out from the expression,

\(f(x)=-3x^2+6x-9\)

Taking -3 as the common terms out of the entire function,

\(\begin{aligned}f(x)&=-3x^2+6x-9\\\\&=-3(x^2-2x+3)\end{aligned}\)

According to the given report, the average length of stay for a hospital's flu-stricken patients is 4.1 days with a maximum stay of 18 days and a recovery rate of 95%.

An auditor selected a random group of flu-stricken patients, and she wants to know the probability of patients recovering within four days.According to the given data, we know that the average length of stay for a flu-stricken patient is 4.1 days and a recovery rate of 95%.

Therefore, the probability of a flu-stricken patient recovering within 4 days is:P(recovery within 4 days) = P(X ≤ 4) = [4 - 4.1 / (1.18)] = [-0.085 / 1.086] = -0.078The above probability is a negative value. Therefore, we cannot use this value as the probability of a patient recovering within four days. Hence, we need to make use of the Z-score formula.

Hence, we can calculate the Z-score using the above equation.The Z-score value we get is -0.85. We can find the probability of a flu-stricken patient recovering within four days using a Z-table or Excel functions. Using the Z-table, we can get the probability of a Z-score value of -0.85 is 0.1977.The probability of patients recovering within four days is approximately 0.1977, which means that out of 100 flu-stricken patients, approximately 20 patients will recover within four days.
