Sine 35 degrees = x / 20

x = sine 35 degrees * 20

x = .57358 * 20

x = 11.4716

What is the measurement of a cube’s side with a surface area of 1,350 square feet?

liq [111]

To solve this, we would divided 1,350 by 6, because the cube has 6 sides and the number 1,350 represents all 6 sides added together. 1,350/6 = 225. Therefore, the answer is 225 ft

Use the drop-down menus to complete the statements. The ordered pair given in the first row in the table can be written using fu

kvv77 [185]

f(x) is read is function f of x.

Where x is the input variable and function f(x) gives output value of function for x input value.

For the given function, we have f(3).

If we compare f(3) by f(x), the x represented by input value 3.

Therefore, x value is 3 there.

And we also have f(x) =-5.

Because function value is -5. So we can read it as, "for x input value of the the function gives output value -5."

For the asked value of x is just x=3.

A recent survey found that 30% of telephone users have switched completely to cell phone use (i.e. they do not have landlines in

Genrish500 [490]

Answer:

The probability that exactly 30% of these 10 telephone users do not have landlines in their homes is 0.2668.

Step-by-step explanation:

We are given that a recent survey found that 30% of telephone users have switched completely to cell phone use (i.e. they do not have landlines in their homes).

A random sample of 10 of these customers is selected.

The above situation can be represented through binomial distribution;

$P(X = r) = \binom{n}{r}\times p^{r} \times (1-p)^{n-r}; x = 0,1,2,3,......$

where, n = number of trials (samples) taken = 10 customers

r = number of success = 30% of 10 = 3

p = probability of success which in our question is the probability

that telephone users do not have landlines in their homes,

i.e. p = 30%

Let X = Number of telephone users who do not have landlines in their homes

So, X ~ Binom(n = 10, p = 0.30)

Now, the probability that exactly 30% of these 10 telephone users do not have landlines in their homes is given by = P(X = 3)

P(X = 3) = $\binom{10}{3}\times 0.30^{3} \times (1-0.30)^{10-3}$

= $120 \times 0.30^{3} \times 0.70^{7}$

= 0.2668

2x+6=3x+4 Write a real-world problem that can be represented by the given equation. Explain what your variable represents.

Slav-nsk [51]

Here, we are required to write a real-world problem that can be represented by the given equation

On the left hand side of the equation, we can say that :

The addition of 6 to twice my cousin's age which gives 2x+6.

On the right hand side, we can say the addition of 4 to thrice my cousin's age which also gives:

3x +4

Ultimately, the real-world problem may be in the form :

Six added to Twice my cousin's age is equal to 4 added to thrice his age.

Also, my variable, x represents my cousin's age.
