Answer:

33

Step-by-step explanation

22 divided by 2 is 11

it says four years ago so add 11 and 4 and that equals 15

she is 15 right now. then add 22 which is 37 and subtract 4 which your answer would be 33

Answer: y = 5x + 26

Step-by-step explanation:

To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Substituting the values, we get:

y - 1 = 5(x - (-5))

Simplifying further:

y - 1 = 5(x + 5)

Expanding the brackets:

y - 1 = 5x + 25

Rearranging the equation to the slope-intercept form (y = mx + b):

y = 5x + 26

Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.

To test the hypothesis that the mean weight of two sheets is equal (μ1 - μ2) against the alternative that it is not, and assuming equal variances, we can use a two-sample t-test. The t-statistic can be calculated using the following formula:

t = (x1 - x2) / (s_p * sqrt(1/n1 + 1/n2))

where:

x1 and x2 are the sample means of the two sheets,

s_p is the pooled standard deviation,

n1 and n2 are the sample sizes.

The pooled standard deviation (s_p) can be calculated using the following formula:

s_p = sqrt(((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2))

where:

s1 and s2 are the sample standard deviations.

To calculate the t-statistic, we need the sample means, sample standard deviations, and sample sizes.

Once you provide the specific values for these variables, I can assist you in calculating the t-statistic to 3 decimal places.

To test the hypothesis that the mean weight of the two sheets is equal (μ1 - μ2) against the alternative that it is not, we can use a paired t-test assuming equal variances. The paired t-test is used when we have paired data or measurements on the same subjects or objects.

The t-statistic for a paired t-test is calculated as follows:

t = (X1 - X2) / (s / √n)

where X1 and X2 are the sample means of the two samples, s is the pooled standard deviation, and n is the number of pairs.

Please provide the sample means, standard deviation, and sample size for each sheet so that we can calculate the t-statistic to 3 decimal places.

According to the Central Limit Theorem, for a sufficiently large sample size, the distribution of sample means will be approximately normal, regardless of the shape of the population distribution.

To calculate the probability, we need to convert the sample mean score to a z-score and then find the corresponding area under the standard normal distribution curve.

Calculate the standard error of the mean (SE):

SE = σ / sqrt(n)

SE = 127 / sqrt(72)

SE ≈ 14.96

Calculate the z-score:

z = (X - μ) / SE

z = (567 - 572) / 14.96

z ≈ -0.334

Find the probability corresponding to the z-score:

We can find the area to the left of the z-score -0.334. Let's denote this probability as P(z < -0.334).

The probability that the sample mean score is less than 567 is approximately equal to P(z < -0.334).

Hoped this helped!

Answer: x = 13, Angle ABE = 51°

Step-by-step explanation:

Since angle ABC is 90° and angle EBC is 39°, subtract them.

90° - 39° = 51°

This means that angle ABE equals 51°. Plug in 51° as the y in the equation y = 3(x+4).

51 = 3 (x + 4)

Multiply 3 by x and 4.

51 = 3x + 12

Subtract both sides by 12.

39 = 3x

Divide both sides by 3.

x = 13

2. Create a tally mark (a vertical line) for each observation that falls into that interval/category.

3. After every fifth tally mark, draw a diagonal line across the previous four tally marks to make counting easier.

4. Add up the total number of tally marks in each interval/category to determine the frequency.

The True Statement is

A. If P'Q'R'S' is formed by translating PQRS 4 units to the right and 5 units down, then PQRS is not necessarily equal to P'Q'R'S'.

Translation is a rigid transformation that preserves the shape and size of the original figure but may change its position.

B. If P'Q'R'S' is formed by reflecting PQRS over the x-axis and then over the y-axis, then PQRS is not necessarily equal to P'Q'R'S'.

Double reflection over perpendicular lines is equivalent to a 180-degree rotation, which may change the orientation of the original figure.

C. If P'Q'R'S' is formed by rotating PQRS 60° about the origin, then PQRS is not necessarily equal to P'Q'R'S'.

Rotation preserves the shape and size of the original figure but changes its orientation and position.

D. If P'Q'R'S' is formed by rotating PQRS 90° clockwise about point Q, and P"Q"R"S" is formed by rotating P'Q'R'S 270° counterclockwise, then PQRS = P"Q"R"S".

The total rotation is equivalent to a 180-degree rotation about point Q, which preserves the shape and size of the original figure.

E. If P'Q'R'S' is formed by reflecting PQRS over the line y=x and P"Q"R"S" is formed by rotating P'Q'R'S 90° clockwise, then PQRS = P"Q"R"S". Reflecting over the line y=x is equivalent to a 90-degree counterclockwise rotation, so the two transformations cancel each other out, and the resulting figure is congruent to the original.

When x = 2, y = 3(2^2) = 3(4) = 12. So the value of y when x = 2 is 12.

a. The flow is physically possible, b. The flow is rotational, c. The velocity potential function is φ(x,y) = x^2y - xt^2 + yt^2, d. The stream function is ψ(x,y) = x^2 - y^2 + 10xyt, e. The flow is not permanent.

a. The flow is physically possible because the velocity field is defined everywhere and is continuous.

b. The flow is rotational because the curl of the velocity field is not zero. The curl of the velocity field is given by:

curl(u,v) = (-2y + 20t, 2x - 20t, 0)

The curl is not zero because the z-component is not zero. This means that the flow has vorticity, which is a measure of how much the fluid is rotating.

c. The velocity potential function is given by:

φ(x,y) = x^2y - xt^2 + yt^2

The velocity potential function is a scalar field that can be used to calculate the velocity field. The velocity field can be calculated using the following formula:

u = -grad(φ)

v = -grad(ψ)

where φ and ψ are the velocity potential functions.

d. The stream function is given by:

ψ(x,y) = x^2 - y^2 + 10xyt

The stream function is a scalar field that can be used to calculate the streamlines of the flow. The streamlines are the curves that are tangent to the velocity field.

e. The flow is not permanent because the velocity field is not time-independent. The velocity field depends on the time variable t. This means that the flow will change over time.

The final expression is x⁵ / (y⁷ * z³).To write the expression so that all exponents are positive, we can use the following rules:
1. For positive exponents, leave the term as it is.
2. For negative exponents, move the term to the denominator and change the sign of the exponent.

Applying these rules to the given expression x⁵y⁻⁷z⁻³, we can rewrite it as:

x⁵ / (y⁷ * z³)

In this expression, x⁵ remains in the numerator since it already has a positive exponent. However, both y⁻⁷ and z⁻³ have negative exponents, so we move them to the denominator and change the signs of their exponents.

Thus, the final expression is x⁵ / (y⁷ * z³).

Note: The term y⁻⁷ in the numerator becomes y⁷ in the denominator, and the term z⁻³ in the numerator becomes z³ in the denominator.
