the ratio of vases to flowers is 2:6.If there are 24 flowers,how many vases are there?type of proportion and answer​

Answer:

3

Step-by-step explanation:

Slope is given by

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

where y2 = -1, y1 = -7, x2 = -1, x2 = -3

[tex] \frac{ - 1 - ( - 7)}{ - 1 - ( - 3)} = \frac{ - 1 + 7}{ - 1 + 3} [/tex]

[tex] = \frac{6}{2} = 3[/tex]

Answer:

D) [tex]y> -\frac{1}{6} x +1[/tex]

The true statement is (b) 3 is in the domain of f º g.

The functions are given as:

[tex]f(x) = \sqrt{x + 9[/tex]

g(x) = 9x - 4

The function f º g(x) is calculated using:

f º g(x) = f(x)* g(x)

This gives

[tex]f\ o\ g(x) = \sqrt{x + 9} *(9x - 4)[/tex]

Set the radicand greater to 0

[tex]x + 9 \ge 0[/tex]

Solve for x

[tex]x \ge - 9[/tex]

This means that the domain is greater than or equal to -9

Hence, the true statement is (b) 3 is in the domain of f º g.

Since Point B is a point of tangency, there is a right angle being created on the edge of that circle.

This means that the Pythagorean Theorem can be applied to solve for r.

[tex]a^2+b^2=c^2[/tex]

[tex]r^2+24^2=(16+r)^2[/tex]

*A common mistake here is distributing the square to both 16 and r, whereas you should be multiplying 16+r by itself (FOIL).*

[tex]r^2+576=r^2+32r+256[/tex]

The [tex]r^2[/tex]s cancel.

[tex]32r+256=576[/tex]

[tex]32r=320[/tex]

[tex]r=10[/tex]

The radius r of Circle C is 10.

The statement fourth "The population is all text messages she sent and the sample is the 50 text messages she randomly selected" is correct.

Simple random sampling is a sampling strategy in which every item in the population has an equal probability of being chosen for the sample.

We have:

A student would like to know what proportion of the text messages she sends is to her best friend.

The number of sample methods she selects =  50 text messages

As the sample consists of the 50 texts she randomly chose from the population of all the texts she sent.

Thus, the statement fourth "The population is all text messages she sent and the sample is the 50 text messages she randomly selected" is correct.

Answer:

Step-by-step explanation:

x+102+115+(180-115)=360

x+282=360

x=78 degrees

y=115 degrees

Answer:

x = 78

y= 115

Step-by-step explanation:

On the angle where p and m meet, we have congruent angles that both equal 102 degrees. The adjacent angles will add up to 180 degrees on a line. So, to find the missing angle, do this:

180-102 = 78 degrees

x is equal to the top right angle where p meets m as they are congruent.

x = 78

You can find y by realizing that the given angle on q meets n are congruent angles. If this angle equals 115 degrees, then y must also equal 115 degrees.

Answer:

89·98 mph

Step-by-step explanation:

First, we get the circumference of the tires:

Circumference = [tex]\pi[/tex] × (radius × 2)

Circumference = 3.142 × (1·5 × 2)

Circumference = 3·142 × 3

Circumference = 9·426 ft

The circumference of the tire is equal to one round.

      1 round = 9·426 ft

840 rounds = ?

We cross multiply to get the length that the tires would cover in a minute

= 840 × 9·426

       1

    1 minute = 7917·84 ft

60 minutes = ?

60 × 7917·84

          1

= 475070·4 ft

      5280 feet = 1 mile

475070·4 feet = ?

475070·4 × 1

     5280

475070·4 ÷ 5280 = speed of the car in mph

89·97545

Round this off to 2 decimal places...

= 89·98 mph

Answer:

a) 0.172 probability that, in a year, there will be 4 hurricanes.

b) The expected number of years with 4 hurricanes is 7.7.

c) 7 years is close to the expected value of 7.7, which means that the Poisson distribution works well here.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

The mean number of hurricanes in a certain area is 5.1 per year.

This means that [tex]\mu = 5.1[/tex]

a. Find the probability that, in a year, there will be 4 hurricanes.

This is P(X = 4).

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 4) = \frac{e^{-5.1}*(5.1)^{4}}{(4)!} = 0.172[/tex]

0.172 probability that, in a year, there will be 4 hurricanes.

b. In a 45-year period, how many years are expected to have 4 hurricanes?

Each year, 0.172 probability of 4 hurricanes. So for 45 years, the mean is 45*0.172 = 7.7.

The expected number of years with 4 hurricanes is 7.7.

c. How does the result from part (b) compare to a recent period of 45 years in which 7 years had 4 hurricanes? Does the Poisson distribution work well here?

7 years is close to the expected value of 7.7, which means that the Poisson distribution works well here.

At the beginning of the Occupation, the Nazis basically let the Jews go about their business. This all changes in October 1940. Measures are introduced one after the other. Civil servants must sign an official declaration stating whether they are Jewish or not. Just like in Germany earlier on, Jewish civil servants and teachers are fired from their jobs.
