Answer:

90

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

x+x+10 +x+50 = 180

3x+60= 180

3x = 180-60

3x = 120

Divide by 3

3x/3 = 120/3

x = 40

The largest angle is

x+50

40+50 = 90

We have to,

find the measure of the largest angle.

Given that,

The angles in a triangle are represented by x, x+10, and x+50.

Let's start to solve,

→ x+ (x+10) + (x+50) = 180°

→ x + x + x = 180° (-50-10)

→ 3x = 180° -60

→ 3x = 120

→ x = 120/3

→ [x = 40°]

Then the value of x + 10,

→ x + 10

→ 40 + 10

→ 50°

Then the value of x + 50,

→ x + 50

→ 40 + 50

→ 90°

The measure of the largest angle is,

→ D. 90 degrees

Thus, option (D) is the correct answer.

The solution is,  the area of the triangle. ABC is 10 cm^2.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

from the given diagram, we get,

we have to find the area of the triangle. ABC

now, we have,

using the Pythagorean theorem, we get,

BD = √AB² - AD²

     =√50 - 45

     =√5

now, we know that,

area of triangle = 1/2 * base * height

                          = 1/2 * √5 * 4√5

                          = 10

Hence, The solution is,  the area of the triangle. ABC is 10 cm^2.

Answer:

[tex]y = 0.35x + 35[/tex]

Step-by-step explanation:

Linear equation:

A linear equation has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept.

Finding the slope:

We have two points: (110, 73.5) and (760, 301).

The slope is given by the change in y divided by the change in x. So

Change in y: 301 - 73.5 = 227.5

Change in x: 760 - 110 = 650

Slope: [tex]m = \frac{227.5}{650} = 0.35[/tex]

So

[tex]y = 0.35x + b[/tex]

Finding the y-intercept:

(760, 301) means that when [tex]x = 760, y = 301[/tex]. So

[tex]301 = 0.35(760) + b[/tex]

[tex]b = 301 - 0.35(760)[/tex]

[tex]b = 35[/tex]

So

[tex]y = 0.35x + 35[/tex]

Then, cross multiply

6×X=6x

Answer:

Step-by-step explanation:

To make this is as easy as possible: a relation is a function if the coordinates don't share an x value. For example, look at the table in B. There is an x value of -1 used twice. That is not a function. Look at C. There are 2 points located at x = -1 (-1, 1) and (-1, -5) are the coordinates. C is not a function. Look at D, made up of coordinate pairs. There are 2 coordinate pairs that have x values of 3; this is not a function. A is a function.

a) Average age of girls is also 151.

b)  [tex]h_{10}=144cm[/tex]

Step-by-step explanation:

From the question we are told that:

Average height of the boys at age [tex]h_9= 137 cm[/tex]

Average height of the boys at age [tex]h_11= 151 cm[/tex]

a)

Since

The average height of all the children was 151 cm.

This implies that The average height of all children is 151

Therefore

Average age of girls is also 151.

b)

Assuming all factors being equal

Height of 10 year old boy

[tex]h_{10}=\frac{h_9+h_11}{2}[/tex]

[tex]h_{10}=\frac{137+151}{2}[/tex]

[tex]h_{10}=144cm[/tex]

Answer:

Hello,

I don't know the words used for that binominal exercice.

Step-by-step explanation:

The probability that the waiter will drop exactly four of the next ten is 0.2

Probability is the extent to which an event is likely to occur, measured by the ratio of the favorable cases to the whole number of cases.

Now it is given that,

Waiter drops hamburgers = 30%

Therefore, Probability of drop, p = 0.3

Now For the next ten,

⇒ number of trials, n = 10

⇒ q = 1 - p = 1 - 0.3

⇒ q = 0.7

Thus, probability that he will drop exactly four of the next ten,

P(x = x) = nCx * p^x * q^(n-x)

For exactly 4, x = 4

⇒ P(x = 4) = ¹⁰C₄ * 0.3^4 * 0.7^(10 - 4)

⇒ P(x = 4) = 210*0.0081*0.1176

⇒ P(x = 4) = 0.2

Thus, the probability that the waiter will drop exactly four of the next ten is 0.2

Answer:

Domain: [-5, 4]

Range: [-5, 0] U (2, 4]

Step-by-step explanation:

The domain encompasses whatever the input (in this case, the horizontal values) can be and the range is what the output (in this case, the vertical values) can be.

As shown on the graph, all horizontal values including and between -5 and 4 are used on the graph. It does not matter that they are on two separate lines. Therefore, the domain is [-5, 4]. Note that the closed brackets signify that -5 and 4 are used

The y values used in the bottom line range from -5 to 0, and in the top one they range from 2 to 4 (not including the 2, as shown by the open circle). Therefore, the bottom range is [-5, 0] and the top range is (2, 4]. We can combine these to say the range is [-5, 0] U (2, 4]

Answer:

  3/(x +1) -4/(x +1)^2

Step-by-step explanation:

The partial fraction expansion will be of the form ...

  A/(x+1)^2 +B/(x+1)

We can find the values of A and B by writing the sum of these terms:

  = (A +B(x +1))/(x +1)^2

Then we require ...

  B = 3

  A +B = -1   ⇒   A = -4

So, the desired expansion is ...

=============================================================

Explanation:

Focus entirely on the triangle on the right side. The other parts of the drawing are not necessary. In my opinion, they are distracting filler.

Refer to the diagram below.

We have an unknown adjacent side, let's call it x, that's along the horizontal part of the triangle.

The hypotenuse however is known and it is 19 ft

We use the cosine ratio to tie the two sides together

cos(angle) = adjacent/hypotenuse

cos(75) = x/19

19*cos(75) = x

x = 19*cos(75)

x = 4.9175618569479 which is approximate

x = 4.9

The base of the ladder is roughly 4.9 feet away from the base of the house.

Answer:

0.6121 = 61.21% probability that the sample average amount of time taken on each day is at most 11 min.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

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.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Normal distribution with mean value 10 min and standard deviation 3 min.

This means that [tex]\mu = 10, \sigma = 3[/tex]

First day:

5 individuals, so [tex]n = 5, s = \frac{3}{\sqrt{5}}[/tex]

The probability is the p-value of Z when X = 11. So

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

By the Central Limit Theorem

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

[tex]Z = \frac{11 - 10}{\frac{3}{\sqrt{5}}}[/tex]

[tex]Z = 0.745[/tex]

[tex]Z = 0.745[/tex] has a p-value of 0.7719.

Second day:

6 individuals, so [tex]n = 6, s = \frac{3}{\sqrt{6}}[/tex]

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

[tex]Z = \frac{11 - 10}{\frac{3}{\sqrt{6}}}[/tex]

[tex]Z = 0.817[/tex]

[tex]Z = 0.817[/tex] has a p-value of 0.793.

What is the probability that the sample average amount of time taken on each day is at most 11 min?

Each day is independent of other days, so we multiply the probabilities.

0.7719*0.793 = 0.6121

0.6121 = 61.21% probability that the sample average amount of time taken on each day is at most 11 min.

The answer at the end of the day would be 4
