Answer: 4 hours

Step-by-step explanation:

First, set up an equation. We know that Bob spent $30 on playing paintball so we use that as our 'answer.' We need to find how many hours Bob played so we need to use x, a variable to find it. We also add 16 because we need to account for the entry fee.

3.50x + 16 = 30

Secondly, solve for x. Move 16 across the equal sign(=). Every time you move across the =, you're going to want to change the sign (if it's addition or subtraction). Since it was +16 and we're moving it, it's now -16.

3.50x = 30 - 16

Calculate 30 - 16 = 14.

Now we have

3.50 x = 14.

To calculate x, we're going to need to divide 3.50 from x. Since we multiplied by x we need to do the opposite across the =.

x = 14 / 3.50

x = 4

Answer:

81,000

Step-by-step explanation:

Based on the information provided, we cannot definitively say whether the county rate is higher than the state rate. The reason for this is because the confidence intervals for both rates overlap.

Since these intervals overlap, there is a chance that the true rate for the county is lower than the true rate for the state, even though the point estimate (i.e. the reported rate) for the county is higher than the point estimate for the state.

To be more precise, we can use the margin of error for each estimate to calculate the range of values that could reasonably contain the true rate. For the county rate, the margin of error is (14.9-10.3)/2 = 2.3. For the state rate, the margin of error is (11.3-9.8)/2 = 0.75.

Therefore, the range of confidence intervals values that could reasonably contain the true rate for the county is (10.3-2.3, 10.3+2.3) = (8, 12.6), and the range of values that could reasonably contain the true rate for the state is (9.8-0.75, 9.8+0.75) = (9.05, 10.55).

As we can see, the two ranges of confidence intervals overlap, indicating that we cannot say with certainty that the county rate is higher than the state rate. We can only say that the county rate is higher than the state rate at the reported significance level (i.e. 95%), but there is still a chance that this result is due to chance or sampling variability.

Answer:

C. 43.11°

Step-by-step explanation:

The formula to use in finding m<BCD = ½ the difference of the intercepted arcs AE and BD

Thus:

m<BCD = ½(AE - BD)

m<BCD = ½(112.54 - 26.32)

m<BCD = ½(86.22)

m<BCD = 43.11°

Answer:

m∠RMS = 20°

Step-by-step explanation:

Find ∠RMS and look at the two values it crosses.

∠RMS crosses through 180 and 160.

Find the difference between the two values to get the measure:

180 - 160 = 20°

So, m∠RMS = 20°

(Its also an acute angle.)

Answer:

20

Step-by-step explanation:

The mistake is in using 160 as the answer. It isn't.

The angle is very small well under 90. It is acute.

The horizontal part of the angle is on 180 degrees of the protractor.

Therefore the angle size is 180 - 160 = 20 degrees.

The stream velocity has no influence on the amount of dissolved load it contains. The amount of dissolved material depends on erosion and deposition carried out in the watercourse. These are affected by factors such as the slope of the land, the resistance of the material to erosion, the size of the sediments transported, etc.

Stream velocity plays an important role in the transport of sediments and dissolved loads in a watercourse. It affects the erosion and deposition processes that occur in the watercourse, which in turn affect the amount of sediment and dissolved load that is carried by the stream. For example, faster stream velocities can cause more erosion of the stream bed, leading to more material being carried in the water.

Sediment is any particulate matter that is transported by a fluid, and it can come in many different forms. The three main types of sediment are:

Using the cosine rule, the distance the plane has flown during Jack's phone call can be calculated by taking the square root of the sum of the squares of the initial and final distances, minus twice their product, multiplied by the cosine of the angle difference.

To determine the distance the plane has flown during Jack's phone call, we can use the cosine rule in trigonometry.

The cosine rule relates the lengths of the sides of a triangle to the cosine of one of its angles.

Let's denote the initial distance from Jack to the plane as d1 and the final distance as d2.

We know that the altitude of the plane remains constant at 2400 meters.

According to the cosine rule:

\(d^2 = a^2 + b^2 - 2ab \times cos(C)\)

Where d is the side opposite to the angle C, and a and b are the other two sides of the triangle.

For the initial angle of elevation (70°), we have the equation:

\(d1^2 = (2400)^2 + a^2 - 2 \times 2400 \times a \timescos(70)\)

Similarly, for the final angle of elevation (50°), we have:

\(d2^2 = (2400)^2 + a^2 - 2 \times 2400 \times a \times cos(50)\)

To find the distance the plane has flown, we subtract the two equations:

\(d2^2 - d1^2 = 2 \times 2400 \times a \times (cos(70) - cos(50))\)

Now we can solve this equation to find the value of a, which represents the distance the plane has flown.

Finally, we calculate the square root of \(a^2\) to find the distance in meters.

It's important to note that the angle of elevation assumes a straight-line path for the plane's movement and does not account for any changes in altitude or course adjustments that might occur during the phone call.

There are 84 unique 4-digit integers (excluding leading zeros) whose sum of the digits is 6.

To find the number of unique 4-digit integers (excluding leading zeros) where the sum of the digits is 6, we can use a combinatorial approach.

Let's consider the four digits as four distinct positions: A, B, C, and D. The sum of the four digits is 6, so we need to distribute these six units among these four positions.

We can solve this problem using stars and bars. Imagine we have six stars (representing the six units) and three bars (representing the three dividers between the positions). The bars help us separate the units into four distinct positions.

For example, if we have the configuration "* | * * | * * | *," it represents the digits 1, 2, 2, and 1. The sum of these digits is 6.

The number of ways to arrange the six stars and three bars is given by the binomial coefficient (6 + 3 choose 3). Using the formula for combinations, we have:

(6 + 3) C 3 = (9 C 3) = 9! / (3! * (9 - 3)!) = 84.

So, there are 84 unique 4-digit integers (excluding leading zeros) whose sum of the digits is 6.

Answer: 12

Step-by-step explanation: hope this helped

Answer:

12

Step-by-step explanation:

divide 48 and 4. 48/4=12

a)The polar form of z is :|z|(cosθ + isinθ) = √10(cos(-18.43°) + isin(-18.43°))≈ 3.16(cos(-18.43°) + isin(-18.43°))≈ 3.02 - 0.94i ; b) The polar form of 2 - 2i is: 2√2(cos(-45°) + isin(-45°))= 2 - 2i ; c) The fourth roots of -3 + i are approximately: 1.39 + 0.09i, 0.35 + 1.36i, -1.39 - 0.09i, and -0.35 - 1.36i.

a. Polar form of z: The polar form of z is given by: r(cosθ + isinθ)where r is the magnitude of the complex number z, given by r = |z| = √(a²+b²), and θ is the argument of the complex number, given by θ = arctan(b/a).

For z = -3 + i, we have a = -3 and b = 1, so :r = |z| = √((-3)²+1²) = √10θ = arctan(b/a) = arctan(1/-3) = -18.43° (since a is negative and b is positive)

Therefore, the polar form of z is :|z|(cosθ + isinθ) = √10(cos(-18.43°) + isin(-18.43°))≈ 3.16(cos(-18.43°) + isin(-18.43°))≈ 3.02 - 0.94i

(b) 2-2i:

To find the modulus of 2 - 2i, we use the formula :r = |z| = √(a²+b²) where a = 2 and b = -2,

so: r = |2 - 2i| = √(2²+(-2)²) = 2√2

To find the argument of 2 - 2i, we use the formula:θ = arctan(b/a) where a = 2 and b = -2, so:

θ = arctan(-2/2)

= arctan(-1)

= -45°

Therefore, the polar form of 2 - 2i is: 2√2(cos(-45°) + isin(-45°))

= 2 - 2i

(c) Fourth roots of z: To find the fourth roots of z = -3 + i,

we can use the formula for finding nth roots of a complex number in polar form: \(r(cosθ + isinθ)^1/n = (r^(1/n))(cos(θ/n)\) + isin(θ/n)) where r and θ are the magnitude and argument of the complex number, respectively.

From part (a), we have: r = √10 and θ = -18.43°, so the fourth roots of z are:

\((√10)^(1/4)(cos(-18.43°/4 + k(360°/4)) + i sin(-18.43°/4 + k(360°/4)))\) where k = 0, 1, 2, or 3.

Evaluating this expression for each value of k,

we get the four roots: 1.44(cos(-4.61°) + i sin(-4.61°))

≈ 1.39 + 0.09i1.44(cos(80.39°) + isin(80.39°))

≈ 0.35 + 1.36i1.44(cos(165.39°) + isin(165.39°))

≈ -1.39 - 0.09i1.44(cos(-99.61°) + isin(-99.61°))

≈ -0.35 - 1.36i

Therefore, the fourth roots of -3 + i are approximately: 1.39 + 0.09i, 0.35 + 1.36i, -1.39 - 0.09i, and -0.35 - 1.36i
