Answer:

m<1 = 40°

m<2 = 118°

m<3 = 71°

Step-by-step explanation:

✔️m<2 = 180° - 62° (angles in a straight line/supplementary angles)

m<2 = 118°

✔️m<1 = 180° - (118° + 22°) (sum of ∆)

m<1 = 40°

✔️m<3 = 180 - (47 + 62) (sum of ∆)

m<3 = 71°

If m < 9, then 6m - 4 is negative. Therefore, |6m - 4| is equal to -(6m - 4) or -6m + 4. Thus, the expression without absolute value is -6m + 4.

In this situation, the best statistical method to use would be a hypothesis test, specifically a one-sample t-test. This test will help determine if the average weight loss after following the gym's 45-minute workout routine for a month is significantly greater than 5 pounds.

In this situation, the best statistical method to use would be a hypothesis test. The gym's belief that their workout can lead to weight loss greater than 5 pounds can be tested by setting up a null hypothesis (the workout does not lead to weight loss greater than 5 pounds) and an alternative hypothesis (the workout does lead to weight loss greater than 5 pounds). The gym can then collect data on weight loss from participants who complete the workout for a month and use statistical analysis to determine if there is enough evidence to reject the null hypothesis and support the alternative hypothesis.

Step-by-step explanation:

1) Convert 2 1/6 into improper fraction

2) Find the LCM which is 6

3) Subtract like a normal fraction

Answer:

Step-by-step explanation:

Answer:

We have that the sum of two numbers  is 9

this can be written as:

x + y  = 9

where x is the larger number.

Now we want to write:

"the difference between one more than the larger number and twice the smaller number"

First, remember that the difference between A and B is:

A - B

Then "the difference between one more than the larger number and twice the smaller number"

is:

"one more than the larger number" = ( x + 1)

"twice the smaller number" = 2*y

the difference between these is:

(x + 1) - 2*y

Now we can simplify:

We know that:

x + y = 9

then:

y = 9 - x

replacing that in the equation:

(x + 1) - 2*y

we would get:

x + 1 - 2*(9 - x)

x + 1  -18 + 2x

(x + 2x) + (1 - 18)

3x - 17

This means that we can write:

"the difference between one more than the larger number and twice the smaller number"

as: 3x - 17

Measure of central angle = 123°

So,? = 123°

Using the normal distribution, there is a 0.6826 = 68.26% probability that the sample mean will be within 2 points of the population mean.

The z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:

\(Z = \frac{X - \mu}{\sigma}\)

For this problem, the parameters are given as follows:

\(\mu = 40, \sigma = 8, n = 16, s = \frac{8}{\sqrt{16}} = 2\)

The probability that the sample mean will be within 2 points of the population mean is the p-value of Z when X = 40 + 2 = 42 subtracted by the p-value of Z when X = 40 - 2 = 38, hence:

X = 42:

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

Z = (42 - 40)/2

Z = 1

Z = 1 has a p-value of 0.8413.

X = 38:

\(Z = \frac{X - \mu}{s}\)

Z = (38 - 40)/2

Z = -1

Z = -1 has a p-value of 0.1587.

0.8413 - 0.1587 = 0.6826 = 68.26% probability that the sample mean will be within 2 points of the population mean.

Answer:

Step-by-step explanation:

1. The average speed of train A = 60 mph,

   The average speed of train B = 60 / 3/4 = 80 mph

Time it takes for trains to meet = 240/(60 + 80) = 240/140 = 12/7 hours

2. The trains meet in 12/7 hours, each traveling at their own speed.

S = D/T, D = S*T

Therefore we can say:

12/7(60) = distance train A is from Boston = 720/7 miles

12/7(80) = distance train B is from New York = 960/7 miles

The distance from New York would = 960/7 miles

Answer:

m∠JKM = 63°

m∠MKL = 27°

Step-by-step explanation:

Since ∠JKL is a right angle. This means that by summing up both m∠JKM and m∠MKL will result in the same as ∠JKL figure. Thus, m∠JKM + m∠MKL = m∠JKL which is 90° by a right angle definition.

\(\displaystyle{\left(12x+3\right)+\left(6x-3\right) = 90}\)

Solve the equation for x:

\(\displaystyle{12x+3+6x-3 = 90}\\\\\displaystyle{18x=90}\\\\\displaystyle{x=5}\)

We know that x = 5. Next, we are going to substitute x = 5 in m∠JKM and m∠MKL. Thus,

m∠JKM = 12(5) + 3 = 60 - 3 = 63°

m∠MKL = 6(5) - 3 = 30 - 3 = 27°

To calculate the total number of samples in the sample space when randomly sampling 3 objects in order from among 42 objects, we need to consider the concept of permutations.

A permutation is an arrangement of objects in a specific order. In this case, we are interested in the number of permutations when selecting 3 objects from a pool of 42 objects.

The formula to calculate permutations is given by nPr = n! / (n - r)!, where n is the total number of objects and r is the number of objects being selected.

In our case, n = 42 (total objects) and r = 3 (objects being selected). Therefore, the total number of samples in the sample space can be calculated as 42P3.

By substituting the values into the formula, we have 42P3 = 42! / (42 - 3)!

The height of the kite assuming that there is no slack in the string is 86.6 m.

We have given that,

the string of a kite is 100 meters long and it makes an angle of 60°.

and we have to find the height of the kite.

So therefore we know the formula for right angled triangle,

i.e. sinθ = Opposite side/ Hypotenuse

Here θ = 60°

Opposite side = height of the kite = h (say)

Hypotenuse = length of string = 100 m

⇒ sin60° = \(\frac{h}{100}\)

           h = 100sin60°

              = 100 × \(\frac{\sqrt{3} }{2}\)

              = 50 × 1.732

The divergence of the vector field F(x, y, z) = (5x^2 + 7 - sin(xz))i + 0j + (5x^2 + 7 - sin(xz))k is 20x - 2zcos(xz).

To find the divergence of the vector field F(x, y, z) = (5x^2 + 7 - sin(xz))i + 0j + (5x^2 + 7 - sin(xz))k, you need to take the divergence operator (∇ · F).

The divergence of a vector field in Cartesian coordinates is given by the following formula:

∇ · F = (∂Fx/∂x) + (∂Fy/∂y) + (∂Fz/∂z),

where Fx, Fy, and Fz are the x, y, and z components of the vector field F, respectively.

In this case, we have:

Fx = (5x^2 + 7 - sin(xz)),

Fy = 0, and

Fz = (5x^2 + 7 - sin(xz)).

Taking the partial derivatives, we get:

∂Fx/∂x = 10x - zcos(xz),

∂Fy/∂y = 0, and

∂Fz/∂z = 10x - zcos(xz).

Now, substituting these derivatives into the divergence formula, we have:

∇ · F = (10x - zcos(xz)) + 0 + (10x - zcos(xz)).

Simplifying further, we get:

∇ · F = 20x - 2zcos(xz).

Therefore, the divergence of the vector field F(x, y, z) = (5x^2 + 7 - sin(xz))i + 0j + (5x^2 + 7 - sin(xz))k is 20x - 2zcos(xz).

8\(x^{4}\)-3\(x^{3}\)-2\(x^{2}\)+7

Step-by-step explanation:

The first thing to do in this problem is distribute the negative in front of (\(-3x^4+2x^2-5\)). This makes it \(3x^4-2x^2+5\).

From here you can remove the parenthesis and combine like terms. 5\(x^{4}\) combines with 3\(x^{4}\) to get 8\(x^{4}\) and 2 and 5 combine to get 7. The -3\(x^{3}\) and -2\(x^{2}\) cannot combine with anything since they don't share any like terms.

Using the combinations, bring all of the terms back together and you get 8\(x^{4}\)-3\(x^{3}\)-2\(x^{2}\)+7

We need to find the inverse of the function gof (x). First we need to find the composite function gof (x) which is given by:

\(g(f(x)) = g(3x - 6)\)

= x - 1 + 1

Thus,

gof (x) = x.

Now we need to find the inverse of the function gof (x) to obtain

\((gof)^-1 (x).\)

We have gof (x) = x

which implies\((gof)^-1 (x)\)

= gof (x)^-1

= x^-1

= 1/x,

x ≠ 0

Therefore,

\((gof)^-1 (x) = 1/x\)

which is option (3) (x+1) since 1/x can be written as 1/(x+1-1), where (x+1-1) is the denominator of 1/x.
