The project average is 100% of the student's grade, and if the student has the given averages, their course grade would be 89%.

The project average is the only component of the student's grade that is not weighted. The homework average accounts for 20% of the grade, while the quiz average accounts for 80%. Therefore, the project average is 100% of the student's grade. If the student has the given averages, then their course grade can be calculated by multiplying the homework and quiz averages by their respective percentages and adding the two products. In this case, the student's course grade would be (95 * 0.2) + (80 * 0.8) + 88 = 89%. The student's course grade would then be rounded to the nearest whole number, which is 89%.

Answer:

Step-by-step explanation:

The formula for the variance of a sample is:

Variance = Σ (x - average)^2 / (n - 1)

Where n is the sample size and x is each data point.

We are given the variance as 544 and the standard deviation as 4, and we know that:

Standard deviation = sqrt(Variance)

So,

Variance = Standard deviation^2

Variance = 4^2

Variance = 16

Now we have the variance and can find the sample size:

544 = 16 * (n - 1)

n - 1 = 544 / 16

n - 1 = 34

The sample size is n = 35.

The value of M when r = 12 and the value of r when M = 224 are 504 and 8 respectively.

Direct proportionality is expressed as;

M ∝ r²

Hence; M = kr²

Where k is the proportionality constant.

Given that;

First, we determine the proportionality constant.

M = kr²

k = M/r²

Plug in r = 2 and M = 14

k = 14 / (2)²

k = 14/4

k = 7/2

Now, a) the value of M when r = 12 will b;

M = kr²

M = (7/2) × ( 12 )²

M = (7/2) × 144

M = 504

Next, b) the value of r when M = 224

M = kr²

r = √(M/k)

r = √( 224 ÷ 7/2 )

r = 8

Therefore, the values of M and r are 504 and 8 respectively.

The required, given expression is completely factored as  (4y -5)(3x - 5).

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

To factor the expression 12xy - 15x - 20y + 25, we can use the distributive property to factor out a common factor from each of the first two terms and the last two terms:

12xy - 15x - 20y + 25

= (12x)(y) - (15x)(1) - (20)(y) + (5)(5)

= (3x)(4y) - (5)(3x) - (4)(5y) + (5)(5)

= 3x(4y - 5) - 5(4y - 5)

Standard deviation is the square root of the variance. A mean of squared differences the square root of the variance unit-free the covariance.

The standard deviation is a measure of variance from the mean that includes spread, dispersion, and spread. The standard deviation displays a "typical" deviation from the mean. It is a well-liked measure of variability because it retains the original units of measurement from the data set. There is a small variation when data points are near the mean, and a large variation when they are far from the mean. The values' distance from the mean is determined by the standard deviation. The most common method of measuring dispersion is standard deviation, which is based on all values.

Hence, standard deviation is the square root of the variance.

Therefore, standard deviation problem solution is at least 90% of the​ trucks can be expected to travel 55,36 miles or less per year.

Statistics uses variance as a gauge of difference. The following equation of that number is used to determine the average variance in between data and the mean. It includes all data points in with its computations, in contrast to other numeric measures of variability, by comparing the value of each data point to the mean.

Here,

a.

z1 = (23 - 40) / 12 = -1.42

z2 = (40 - 40) / 12 = 0

P(-1.42 < z < 0) = 0.4199

So, approximately 0.4199 or 41.99% of trucks can be expected to travel between 23 and 40 thousand miles in a​ year.

b.

z1 = (30 - 40) / 12 = -0.83

z2 = (60 - 40) / 12 = 1.67

P(z < -0.83) + P(z > 1.67) = 0.2023 + 0.0475 = 0.2498

So, approximately 24.98% of trucks can be expected to travel either less than 30 or more than 60 thousand miles in a​ year.

c.  Thus:

x = 40 + 1.28(12) = 55.36

So, standard deviation problem solution is at least 90% of the​ trucks can be expected to travel 55,36 miles or less per year.

Answer:

  x = 22

  y = 59

Step-by-step explanation:

You want the values of x and y as shown in the figure where angles (2x)° and (y-15)° are vertical angles, and (2x)° and (2x+2)° are complementary.

Two angles are complementary when their sum is 90°.

  (2x)° +(2x+2)° = 90°

  4x = 88 . . . . . . . . . . . divide by °, subtract 2

  x = 22

Vertical angles have the same measure:

  (2x)° = (y -15)°

  2·22 = y -15 . . . . . . divide by °, substitute for x

  59 = y . . . . . . . . .  add 15

The value of x is 22.

The value of y is 59.

Answer: (x^3 - 3x^2 + 5x - 3)/(x^2 - 2)

Step-by-step explanation:

It says the volume equals the height multiplied by the base area, or base area x height = volume. Because we are given the volume and the base area, we can plug in the values to get (x^2 - 2) x height = (x^3 - 3x^2 + 5x - 3). Finally, we can divide both sides by (x^2 - 2) to get height = (x^3 - 3x^2 + 5x - 3)/(x^2 - 2).

Step-by-step explanation:

Find Object Volume Rotation

Suppose That \( R \) Is The Finite Region Bounded By \( Y=X, Y=X+1, X=0 \), And \( X=3 \). find the exact value of the volume of the object we obtain when rotating about the -axis.

The region R is a triangular region defined by the lines y = x, y = x + 1, x = 0, and x = 3. To find the volume of the object obtained by rotating this region about the x-axis, we can use the method of cylindrical shells.

The height of the cylindrical shell is given by the difference between y = x and y = x + 1, or 1 unit. The radius of the cylindrical shell is given by x. Therefore, the volume of the object is given by:

\begin{align*}

V &= \int_{x=0}^{x=3} \pi x^2 \cdot 1, dx \

&= \pi \int_{x=0}^{x=3} x^2, dx \

&= \pi \left[ \frac{x^3}{3} \right]_{x=0}^{x=3} \

&= \pi \left( \frac{27}{3} - \frac{0}{3} \right) \

&= 9\pi

\end{align*}

So the volume of the object is equal to 9π cubic units.

The required slope of the line is -1/4 which passes through points (1,-1) and (5,-2).

The slope of the line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

Given,

Let

x₁ = 1 , y₁ = -1

x₂ = 5, y₂ = -2

∵ Slope m = (y₂ - y₁)/(x₂ -x₁  )

Substitute values in the formula, and we get

m = (-2 - (-1))/(5 - 1)

m = (-2 + 1)/(4)

m = -1/4

Thus, the required slope of the line is -1/4.
