Answer:

The  formula for the area of a parallelogram is base x height.

base x height = area

So, I will form an equation.  b (base)  x 3 ft (height) = 18 1/3

Next divide 3 from 18 1/3, so 18 1/3 divided by 3. This equals1 6 1/9

answer for the 9 question

Answer: x = 14/5.   Because first we Distribute and get 2x + 6 = 8 - 3(x-4) then, we Distribute it again 2x + 6 = 8 - 3x + 12 then we Add the numbers and get 14/5

Answer:

Step-by-step explanation:

2(x +3) = 8 - 3 (x-4)

=> 2x + 6 = 8 - 3x + 12

=> 2x + 3x = 8 - 6 + 12

=> 5x = 14

Answer:

We have the system:

y > x^2 - 1

y < (-1/2)*x + 3

To find the solutions of this set we need to graph the solutions range of both sets, and see the intersection between these solution ranges.

How we do it?

Start with the first one.

First, we graph the equation:

y = x^2 - 1

Now because we are using the symbol ">" means that y is smaller than the thing at the right, then the graph of the equation will be with a dashed line (which means that the points on the line are not solutions) and we will shade all the region above the line

For the other inequality we do the same:

First we graph:

y = (-1/2)*x + 3

And because we have the symbol "<" we again use a dashed line, but this time we will shade all the region below the line.

Once we shaded both regions, the region where we have both shades will be the region of solutions for the system of inequalities.

You can see the graph below.

Step-by-step explanation:

The sum of the short two sides must exceed the length of the longest side. That is not the case for lengths {4, 5, 15} or {5, 5, 10}.

Triangles can be formed from {3, 5, 7} and {4, 5, 6}.

Answer:

490 in.^3

Step-by-step explanation:

volume = length * width * height

volume = 7 in. * 10 in. * 7 in.

volume = 490 in.^3

Volume = edge^(3).

Volume = (7)(10)(7) inches

[tex]a = \frac{u}{k + b} [/tex]

Step-by-step explanation:

Factor out the common term a.

[tex]u = a(k + b)[/tex]

Divide both sides by k + b.

[tex] \frac{u}{k + b} = a[/tex]

Switch sides.

[tex]a = \frac{u}{k + b} [/tex]

Answer:

Step-by-step explanation:

1) The Triangle Sum Theorem states that the sum of the angles in a triangle = 180°

2) The triangle inequality theorem states that the sum of any two sides of a triangle is larger than the third side

3) Isosceles triangle theorem states that the angles opposite the equal sides of an isosceles triangle are congruent

4) Converse of the Isosceles theorem states that the sides opposite the equal angles of an isosceles triangle are congruent

5) Midsegment of a triangle theorem states that the midsegment of two sides of a triangle is equal to half of the side it is parallel to

6) Concurrency of medians theorem states that the medians of a triangle intersect at a point within the triangle

Step-by-step explanation:

1) The Triangle Sum Theorem states that the sum of the angles in a triangle = 180°

Proof: To draw a triangle ABC starting from the point A we move 180° - ∠A to get to ∠B

From ∠B we turn 180° - ∠B to get to ∠C and from ∠C we turn 180° - ∠C to get back to A we therefore have turned 360° to get to A which gives;

180° - ∠A + 180° - ∠B + 180° - ∠C = 360°

Hence;

- ∠A - ∠B  - ∠C = 360° - (180°+ 180°+ 180°) = -180°

-(∠A + ∠B  + ∠C) = -180°

∴ ∠A + ∠B  + ∠C = 180°

2) The triangle inequality theorem states that the sum of any two sides of a triangle is larger than the third side

Proof: Given ΔABC with height h from B to D along AC, then

AC = AB×cos∠A + CB×cos∠C

Since ∠A and ∠C are < 90 the cos∠A and cos∠C are < 1

∴ AC < AB + CB

3) Isosceles triangle theorem

Where we have an isosceles triangle ΔABC with AB = CB, we have by sine rule;

Therefore;

sin(C) = sin(A) hence ∠A = ∠C

4) Converse of the Isosceles theorem

Where we have an isosceles triangle ΔABC with ∠A = ∠C, we have by sine rule;

Therefore;

sin(C) = sin(A) hence AB = CB

5) Midsegment of a triangle theorem states that the midsegment of two sides of a triangle is equal to half of the side it is parallel to

Given triangle ABC with midsegment at DF between BA and BC respectively, we have;

in ΔABC and ΔADF

∠A ≅ ∠A

BA = 2 × DA, BC = 2 × FA

Hence;

ΔABC ~ ΔADF (SAS similarity)

Therefore,

BA/DA = BC/FA = DF/AC = 2

Hence AC = 2×DF

6) Concurrency of Medians Theorem

By Ceva's theorem we have that the point of intersection of the segments from the angles in ΔABC is concurrent when the result of multiplying ratio the ratios of the segment formed on each of the triangle = 1

Since the medians bisect the segment AB into AZ + ZB

BC into BX + XB

AC into AY + YC

Where:

AZ = ZB

BX = XB

AY = YC

We have;

AZ/ZB = BX/XB = AY/YC = 1

∴ AZ/ZB × BX/XB × AY/YC = 1 and the median segments AX, BY, and CZ are concurrent (meet at point within the triangle).

Answer:

0.0485 = 4.85% probability that you miss the bus.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

When two normal distributions are subtracted, the mean is the subtraction of the means, while the standard deviation is the square root of the sum of the variances.

In this question:

We have to find the distribution for the difference in times between when you arrive and when the bus arrives.

You arrive at 8, so we consider the mean 0. The bus arrives at 8:05, 5 minutes later, so we consider mean 5. This means that the mean is:

[tex]\mu = 0 - 5 = -5[/tex]

The standard deviation of your arrival time is of 2 minutes, while for the bus it is 3. So

[tex]\sigma = \sqrt{2^2 + 3^2} = \sqrt{13}[/tex]

The bus remains at the stop for 1 minute and then leaves. What is the chance that I miss the bus?

You will miss the bus if the difference is larger than 1. So this probability is 1 subtracted by the pvalue of Z when X = 1.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1 - (-5)}{\sqrt{13}}[/tex]

[tex]Z = \frac{6}{\sqrt{13}}[/tex]

[tex]Z = 1.66[/tex]

[tex]Z = 1.66[/tex] has a pvalue of 0.9515

1 - 0.9515 = 0.0485

0.0485 = 4.85% probability that you miss the bus.
