Solve for X 3 (x+1)=9

Answer:

[tex]P(F/S)=0.216[/tex]

Step-by-step explanation:

Let's call F the event that the student is female and S the event that the student is senior.

So, we need to find the probability P(F/S) that a student is female given that  the student is a senior. P(F/S) is calculated as:

P(F/S) = P(F∩S)/P(S)

Then, the probability P(F∩S) that a student is female and senior is equal to 0.06

On the other hand, we can calculate the total number of students x using the following equation as:

[tex]\frac{646}{x}+\frac{229}{x}-0.06=1[/tex]

Where 646/x is the percentage of female students, 229/x is the percentage of senior students and 0.06 is the percentage of female seniors.

Then, solving for x we get that the number of students is 825.4719

Additionally, the probability P(S) that a student is a senior is equal to:

[tex]P=\frac{229}{825.47} =0.2774[/tex]

Because there are 825.47 students and 229 are senior.

So, P(F/S) is equal to:

[tex]P(F/S)=\frac{0.06}{0.2774}=0.216[/tex]

Answer:

x=3

Step-by-step explanation:

try different values on the line! plug them in and you'll see that every x value is 3!

Answer:

x=3

Step-by-step explanation:

Because there is no slope (or the slope is undefined), there is another way to write the equation. Instead of y=mx+b, it will be either x=b or y=b, y=b being a horizontal line and x=b being vertical. To find b, simply find the value of x or y. The line has infinite points on it with one similarity, being their x value is 3. Hence, the equation is x=3.

Answer:

782

Step-by-step explanation:

y = -670 + 33(44)

y = -670 + 1452

y = 782

Step-by-step explanation:

Step 1:  Find y when x is 44

[tex]y = -670 + 33x[/tex]

[tex]y = -670 + 33(44)[/tex]

[tex]y = -670 + 1452[/tex]

[tex]y = 782[/tex]

Answer: [tex]? = 782[/tex]

Answer:

2037.75m/s

Step-by-step explanation:

To calculate the speed of a wave, you need to multiply the wavelength by the frequency. In this case, 627*3.25=2037.75m/s. Hope this helps!

The speed of a sound wave with a frequency of 627 hz and a wavelength of 3.25 m is calculated using the formula v = f λ, where v is the speed, f is the frequency, and λ is the wavelength. Multiplying the given frequency and wavelength gives a speed of 2037.75 m/s for the sound wave.

The speed of a sound wave is calculated by multiplying its frequency by its wavelength using the formula v = f λ, where v is the speed of the wave, f is the frequency, and λ (lambda) is the wavelength.

Given that the frequency of the sound wave is 627 hz and the wavelength is 3.25 m, we can substitute these values into the formula to find the speed:

v = 627 hz × 3.25 m

Now, let's perform the multiplication to solve for v:

v = 2037.75 m/s

Therefore, the speed of the sound wave is 2037.75 meters per second.

Answer: 20

Step-by-step explanation:

Given, Sonya wrote each letter of LEDBETTER on a separate index card and put the cards in a box.

Total letters = 9

Number of times T appeared = 2

Thus, if we pick one card , the probability of getting card with T would be :-

[tex]\dfrac{\text{Number of times T appeared}}{\text{Total letters}}\\\\=\dfrac{2}{9}[/tex]

If she performed this experiment 90 times, then the best prediction for the number of times that Sonya would pick a T would be :

90 x ( probability of getting card with T)

[tex]=90\times\dfrac{2}{9}=10\times2=20[/tex]

Hence, the the best prediction for the number of times that Sonya would pick a T = 20.

see explanation

Step-by-step explanation:

To find the x- intercept, where the line crosses the x- axis, let y = 0 in the equation and solve for x, that is

11x + 6 = 0 ( subtract 6 from both sides )

11x = - 6 ( divide both sides by 11 )

x = - [tex]\frac{6}{11}[/tex] , thus coordinates of x- intercept are

( - [tex]\frac{6}{11}[/tex], 0 )

To find the y- intercept, where the line crosses the y- axis, let x = 0 in the equation and solve for y, that is

y = 11(0) + 6 = 0 + 6 = 6, thus coordinates of y- intercept are

(0, 6 )

Answer:

A. 60°

Step-by-step explanation:

There's a very straight-forward explanation for this, thank god! XD

For this type of problem, there's a rule to follow for the outside angle. X and 120 should equal 180, so all you need to do is fill that gap.

180-120 = 60

60 is your answer because it completes the whole angle.

Answer:

each piece will be 3 1/4 inches

Step-by-step explanation:

22 3/4 can be rewritten as 91/4. to divide, you use keep, change, flip (keep the first fraction, change the sign, and flip the second fraction) . u will end up with 91/4 times 1/7, which is 91/28 or 3 1/4

Each piece of ribbon will be 3(1/4) inches.

Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.

[tex]22\dfrac{3}{4}[/tex]

This expression can be rewritten

[tex]\dfrac{88+3}{4} = \dfrac{91}{4}[/tex]

Since ribbon has to be divided into 7 equal pieces

[tex]\dfrac{\dfrac{91}{4}}{7}[/tex]

[tex]\dfrac{91}{4} \times\dfrac{1}{7}[/tex]

[tex]\dfrac{91}{28} = \dfrac{13}{4}[/tex]

[tex]3\dfrac{1}{4}[/tex]
