Find the value of x.

Tatiana [17]

Answer: The answer is x = 6 units.

Step-by-step explanation: Please refer to the attached diagram

The diagram in the question shows two triangles placed on each other and for convenience sake has been labelled ABDCE. Triangle ABC is a right angled triangle, and so is triangle ADE. From the marks on the lines, we can infer that line AD is equal in measurement to line DB. Also line AE is equal in measurement to line EC.

Therefore we can see the similarity in both triangles, if AD and AE equals DB and EC, then it follows that DE equals BC.

Hence if AD = DB and

AE = EC, and

DE = BC

Then, x - 3 = ½x

(½x can also be expressed as x/2)

x - 3 = x/2

By cross multiplication we now have

2(x - 3) = x

2x - 6 = x

By collecting like terms we now have

2x - x = 6

x = 6

The final margin of an NFL football game is approximately normally distributed, with a mean equal to the gambling point spread a

nika2105 [10]

Answer:

The Giants had 0.1949 = 19.49% probability of winning initially.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

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 pvalue, we get the probability that the value of the measure is greater than X.

Mean equal to the gambling point spread and a standard deviation of 14 points. The Patriots had been favored by 12 points.

This means that $\mu = 12, \sigma = 14$

What does that fact imply about the Giants' initial (i.e., pre-game) chances of winning

P(X > 0): Probability of Patriots winning.

P(X < 0): Probability of Giants winning.

So we want to find P(X < 0), which is the pvalue of Z when X = 0. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{0 - 12}{14}$

$Z = -0.86$

$Z = -0.86$ has a pvalue of 0.1949

The Giants had 0.1949 = 19.49% probability of winning initially.

In the diagram at the left, O is the center of the circle, MNOP is a rectangle, and the area of the circle is 100π. What is the

RUDIKE [14]

The length of the diagonal of the rectangle will be 14.142 units.

<h3>What exactly is a rectangle?</h3>

It has four sides and is a polygon. The internal angle total is 360 degrees. The opposing sides of a rectangle are parallel and equal, and each angle is 90 degrees.

Rectangle diagonals are equally equal and meet at the midpoint.

O is the circle's center, MNOP is its rectangle, and the circle's area is 100 in the diagram to the left.

Area of circle=πr²

100 π= πr²

r= 10 units

The length of the rectangle is equal to the radius of the circle is 10 units. The length of the diagonal is √2 times the side of the rectangle;

L=√2 R

L=1.414×10

L=14.14

Hence the length of the diagonal of the rectangle will be 14.142 units.
