The area of the triangle is 36 square units, option C is correct.

A triangle is a three-sided polygon that consists of three edges and three vertices.

We have to find the area of triangle whose base is 4 units and height is 18 units

Area of triangle = 1/2 base ×height

Plug in the values of base and height in the above formula

=1/2×4×18

Divide numerator and denominator by 2

=36 square units

Hence, the area of the triangle is 36 square units, option C is correct.

Answer:

d. 40

Step-by-step explanation:

The number of faces, edges and vertices is related by the following formula:

[tex]V - E + F = 2[/tex]

In which V is the number of vertices, E is the number of edges and F is the number of faces.

In this question:

[tex]F = 25, V = 17[/tex]

We want to find E. So

[tex]V - E + F = 2[/tex]

[tex]17 - E + 25 = 2[/tex]

[tex]E = 42 - 2 = 40[/tex]

Answer:

[tex](a)\ c = \frac{1}{15}[/tex]

[tex](b)\ 40\%[/tex]

[tex](c)\ 60\%[/tex]

Step-by-step explanation:

The given parameters can be represented as:

[tex]P_Y(y) \ge 0, y =1,2,3,4,5[/tex]

[tex]P_y(y) = cy, y=1,2,3,4,5[/tex]

Solving (a): The value of c

To do this, we make use of the following rule;

[tex]\sum\limit^5_{y=1}P_Y(y_i) = 1[/tex]

Given that:

[tex]P_y(y) = cy, y=1,2,3,4,5[/tex]

This is translated to:

[tex]c*1 + c * 2 + c * 3 + c * 4 + c * 5 = 1[/tex]

[tex]c + 2c + 3c + 4c + 5c = 1[/tex]

[tex]15c = 1[/tex]

Solve for c

[tex]c = \frac{1}{15}[/tex]

(b) The proportions of applications that requires at most 3 forms

This implies that: y = 1,2,3

So, we make use of:

[tex]P(Y \le 3) = P(Y=1) + P(y=2) + P(Y=3)[/tex]

Recall that:

[tex]P_y(y) = cy, y=1,2,3,4,5[/tex]

Substitute [tex]c = \frac{1}{15}[/tex]

[tex]P_y(y) =\frac{1}{15}y[/tex]

So:

[tex]P(Y \le 3) = P(Y=1) + P(y=2) + P(Y=3)[/tex]

[tex]P(Y\le 3) = \frac{1}{15} * 1 +\frac{1}{15} * 2 +\frac{1}{15} * 3[/tex]

[tex]P(Y\le 3) = \frac{1}{15} +\frac{2}{15} +\frac{3}{15}[/tex]

Take LCM

[tex]P(Y\le 3) = \frac{1+2+3}{15}[/tex]

[tex]P(Y\le 3) = \frac{6}{15}[/tex]

[tex]P(Y\le 3) = 0.4[/tex]

Express as percentage

[tex]P(Y\le 3) = 0.4*100\%[/tex]

[tex]P(Y\le 3) = 40\%[/tex]

(c) The proportions of applications that requires between 2 and 4 forms (inclusive)

This implies that: y = 2,3,4

So, we make use of:

[tex]P(2 \le Y \le 4) = P(Y=2) + P(Y=3) + P(Y=4)[/tex]

[tex]P(2 \le Y \le 4) = 2 * \frac{1}{15} + 3 * \frac{1}{15} + 4 * \frac{1}{15}[/tex]

[tex]P(2 \le Y \le 4) = \frac{2}{15} + \frac{3}{15} + \frac{4}{15}[/tex]

Take LCM

[tex]P(2 \le Y \le 4) = \frac{2+3+4}{15}[/tex]

[tex]P(2 \le Y \le 4) = \frac{9}{15}[/tex]

[tex]P(2 \le Y \le 4) = 0.6[/tex]

Express as percentage

[tex]P(2 \le Y \le 4) = 0.6 * 100\%[/tex]

[tex]P(2 \le Y \le 4) = 60\%[/tex]

A sample size of approximately 9909 components is needed to estimate the true proportion of defective components within 2.5 percentage points with 99% confidence.

To estimate the true proportion of defective components with a desired level of confidence and precision, we can use the formula for sample size determination in a proportion estimation problem.

The formula is given by:

n = (Z²  p  (1-p)) / E²

Where:

- n is the required sample size,

- Z is the Z-value corresponding to the desired confidence level (in this case, 99% confidence),

- p is the estimated proportion of defective components from the initial sample (20/300 = 0.0667),

- (1-p) is the estimated proportion of non-defective components,

- E is the desired margin of error (2.5 percentage points = 0.025).

Determine the Z-value corresponding to a 99% confidence level. The Z-value can be obtained from a standard normal distribution table or using statistical software. For a 99% confidence level, the Z-value is approximately 2.576.

Substitute the values into the formula:

n = (2.576² * 0.0667 * (1-0.0667)) / (0.025²)

n = (6.641 * 0.9333) / 0.000625

n = 6.194 / 0.000625

n ≈ 9908.8

Therefore, a sample size of approximately 9909 components is needed to estimate the true proportion of defective components within 2.5 percentage points with 99% confidence.

Answer:

4x^3-6x^2-6x+9

Step-by-step explanation:

I would write out the solutions as expressions and expand them:

(x-2)(x-1/2)(x-3/2)

(x^2-1/2x-2x+1)(x-3/2)

(x^2-5/2x+1)(x-3/2)

x^3-(3/2)x^2-(5/2)x+15/4+x-3/2

x^3-(3/2)x^2-(3/2)x+9/4

Next, since the leading coefficient has to be 4x^3, I could just multiply the entire expression by 4:

4x^3-(12/2)x^2-(12/2)x+36/4

4x^3-6x^2-6x+9

Answer:

Step-by-step explanation:

y=1/3x-2 is the slope form of -5x+15y=-30.

a line is an infinitely long object with no width, depth, or curvature.

The given equation is -5x+15y=-30

minus five x plus fifteen y equal to minus thirty.

The standard form or slope form of a line is

y=mx+c

Where m is the slope and c is y intercept.

We need to convert  -5x+15y=-30 to standard form or slope intercept form of a line.

-5x+15y=-30

15y=-30+5x

15y=5x-30

Divide both sides by 15

y=5/15 x-30/15

y=1/3x-2

Hence y=1/3x-2 is the slope form of -5x+15y=-30.

Question:

A number cube with faces labeled from 1 to 6 will be rolled once.  The number rolled will be recorded as the outcome.

Give the sample space describing all possible outcomes.  Then give all of the outcomes for the event of rolling a number greater than 2.

If there is more than one element in the set, separate them with commas.

Answer:

[tex]S = \{1,2,3,4,5,6\}[/tex]

[tex]Greater2 = \{3,4,5,6\}[/tex]

Step-by-step explanation:

Given

A roll of a 6 sided number cube

Solving (a): The sample space

This implies that we list out all number on the number cube.

So:

[tex]S = \{1,2,3,4,5,6\}[/tex]

Solving (b): Outcomes greater than 2

This implies that we list out all number on the number cube greater than 2 i.e. 3 to 6.
