The length of segment CD is 7 units. The length of segment AE is 20.5 units. The m∠BCD is 45 degrees.

A parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

Given that parallelogram ABCD, has m∠ABC = 135° and the length of diagonal AC is 41 units.

The measure of length of side AD is 35 units and length of side AB is 7 units.

WE know that the opposite side of a parallelogram are same. Thus,

The length of segment CD = AB = 7 units.

Also, the length of diagonal AC =  41 units. Then;

The length of segment AE = 1/2 AC = 41/2 = 20.5 units.

Therefore, m∠BCD + m∠ABC  = 180

m∠BCD + 135  = 180

m∠BCD  = 180 - 135

m∠BCD = 45 degrees.

Hence, The length of segment CD is 7 units. The length of segment AE is 20.5 units. The m∠BCD is 45 degrees.

Step-by-step explanation:

The probability is [(X - μ) < 1.1] = 0.6046.

A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Given: σ² = 64

Mean μ = 34

To find: Probability[(X - μ) < 1.1]

Computation:  Standard deviation σ = √σ²

Standard deviation σ = √64

Standard deviation σ = 8

Probability[(X - μ) < 1.1] = Probability[-1.1 < (X - μ) < 1.1]

Probability[(X - μ) < 1.1] = Probability[-1.1/(8/√38) < (X - μ) < 1.1/(8/√38)]

Using z table

The probability =  [(X - μ) < 1.1] = 0.6046.

Ok, so:

Let me draw the situation here below:

Ok, let's find the angle first:

For this, we shall make use of the trigonometric functions:

In this case, the most useful function which could help us to solve this problem is tan(x). This function relations the opposite side of the angle and its adjacent side, like this:

tan(x) = opposite side / adjacent side

So, if we replace the values:

tan(x) = 15/95

tan(x) = 0,15789474

To find x, we could use the inverse function of tan(x). This one is called arctan(x).

So, arctan(tan(x)) = arctan(0,15789474)

And this is:

x = 8.97 degrees

Now, we can affirm that the angle is 8.97 degrees, which is bigger than 8.5 degrees.

Now, what should be the length of the bottom for the ramp to be safe?

Let me draw the situation:

We know that the ramp is safe if the maximum safe incline is 8.5°. So, what should be the value of x for this occurs?

We use the trigonometric function tan(x) again.

tan(8.5°) = 15/x

Remember that tan(8.5°) is a number

Then, x = 15/tan(8.5°), and this is 100.36

So, we conclude that the lenght of the bottom should be at least, 100.36

Given:

5 red marbles

4 blue marbles

1 green marble

Upon choosing green marble, we win $10

Upon choosing blue marble, we win $2

Upon choosing red marble, we win $0

It costs $3 to play each game.

To find:

The expected value of playing the game

Step by step solution:

Firstly we need to calculate the probablity of occuring of each event:

P (Choosing a red marble) = 5/10 = 1/2

P (Choosing a blue marble) = 4/10 = 2/5

P (Choosing a green marble) = 1/10 = 1/10

We will now associate the money related to each case:

= 1/2 × $0 + 2/5 × $2 + 1/10 × $10

= 0 + $ 4/5 + $1

Answer:

8/3 square inches

Explanation:

First, we need to get the height of the triangle BAC

Area of triangle = 1/2 * base * height

6 = 1/2 * 3 * height

12 = 3 * height

Height = 12/3

The height of triangle BAC is 4inches

Next is to get the height of EDF. Since they are both similar hence;

2/3 = h/4

3h = 2 * 4

3h = 8

h = 8/3

h = 8/3in

Hence the height of triangle EDF is 8/3in

Get the area of triangle EDF

Area of triangle EDF = 1/2 * 2 * 8/3

Area of triangle EDF = 8/3 square inches

Hence the area of triangle EDF is 8/3square inches

Answer:

Explanation :

Let us call x, the woman speed as she goes uphill

Now, we know that it took the woman 2 hours to go uphill; therefore, the distance covered is

4* (x)

shortly afterwards, when the woman returns she is walking at x + 2 mph; therefore, the distance she covers is

Since the uphill and the downhill distances ar the same, we have

4x = 2 (x +2 )

4x = 2x + 4

x = 2

Hence, going to the hill, the woman speed is 2 miles per goo

Answer:

(g ◦ h) (x) = 16x² + 12x -4

Step-by-step explanation:

We have

g(x) = x² − 5x

h(x)= 4x + 4

(g ◦ h) (x) = g(h(x))

h(x) = 4x + 4

g(h(x)) = g(4x + 4)

= (4x + 4)² - 5(4x+4)         //substitute 4x + 4 wherever there is an s-term in

(4x + 4)² = 16x² + 32x + 16

5(4x + 4) = 20x + 20

(4x + 4)² - 5(4x+4)  = 16x² + 32x + 16 -(20x + 20)

= 16x² + 32x + 16 - 20x - 20

You have a cone with surface area of 628.32 m². In order to find the volume of the cone you use the following formula:

V= 1/3 π r² h

r: radius of the base of the cone = 15m/2 = 7.5m

h: heigth of the cone

Then, you have to calculate first the height of the cone. To do that, you use the information about the surface area. You use the following formula:

S = πr² + πrl

l: diagonal of the cone

Then, you have to find l, and then you can calculate hYou solve for l from the surface area formula:

l = (S - πr²)/πr = (628.32 - π(7.5)²)/(π(7.5))

l = 19.16

To calculate the heigth of the cone you use the Pythagoras theorem, just as follow:

h = √(l²-r²) = √((19.16)²-(7.5)²) = 17.63m

Next, you can replace the values of h and r into the formula for the Volume:

V= 1/3 π r² h = (1/3)π (7.5m)²(17.63m) = 1038.5m³

Hence, the volume of the given cone is 1038.49 m3

The area of a sector of a circumference is given by the following formula:

Where r is the radius of the circumference, and θ is the angle of the sector in radians.

The radius is already known: 15cm.

We need to estimate the angle of the shaded region. The shaded region and the sector whose angle is 72° form together a 180° angle. (This is according to the figure. That is not said in an explicit way but we will need to assume that since there is not enough information to calculate the area if it is otherwise.)

Then, the angle of the shaded area, plus 72° is 180°:

Now, before applying the formula we need to express the angle in radians. Recalling that 180° is equal to π radians:

Now, we have the angle in radians. We can use the equation:

Solution

For this case we have the following:

x intercept 4: (4,0)

y intercept 2: (0,2)

Then we can find the slope like this:

then the equation is given by:

y= -1/2 x+ 2

The rejection region, or area of the rejection zone, is the significance level. The test's tail determines the direction of the rejection region. When the significance threshold is unknown, it is typically considered to be 5%.

A collection of values for the test statistic for which the null hypothesis is rejected constitutes a critical zone, sometimes referred to as the rejection region. For example, if the observed test statistic is in the critical range, the null hypothesis is rejected and the alternative hypothesis is accepted.

Consider the crucial value as a cut-off point at a particular importance level. If a test statistic falls on one side of the crucial value and leads to the null hypothesis being accepted, a test statistic falling on the other side will lead to the null hypothesis being rejected.

A set of values for the test statistic for which the null hypothesis is accepted is referred to as a confidence interval and is also referred to as the acceptance area. For example, if the observed test statistic is within the confidence interval, the null hypothesis is accepted and the alternative hypothesis is rejected.
