Answer:

[tex]\frac{\sqrt{3}}{2}[/tex]

Step-by-step explanation:

Let's take a look at the unit circle below.

Remmeber that cos represents the x-value and that sin represents the y-value.

We see that:

[tex]sin(30)= \frac{1}{2}\\\text{and}\\ cos(30) = \frac{\sqrt{3}}{2}[/tex]

Now we just multiply all the together and we get:

Show that x = -5 is a solution to the inequality 18x − 42 ≠ 7x

Answers

Answer:

See Below

Step-by-step explanation:

Put -5 in place of x

18(-5)-42 does not equal 7(-5)

-90-42 does not equal -35

-90-42=-132, not -35

The value x = -5 is a solution to the inequality 18x − 42 ≠ 7x.

What is inequality?

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than, or < ‘less than.

For showing x =-5 is a solution of the inequality 18x − 42 ≠ 7x put x =-5 in the solution if it satisfies the condition then it is a solution of the given inequality.

18x − 42 ≠ 7x

18 x ( -5 ) - 42 ≠ 7 x ( -5 )

-132 ≠ -35

The value x = -5 is satisfying the given inequality. Hence, x = -5 is a solution to the inequality 18x − 42 ≠ 7x.

If each customer takes 3 minutes to check out, what is the probability that it will take more than 9 minutes for all the customers currently in line to check out?

Answers

Using a discrete probability distribution, it is found that there is a 0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.

What is the discrete probability distribution?

Researching the problem on the internet, it is found that the distribution for the number of customers in line at the store is given by:

P(X = 0) = 0.2;P(X = 1) = 0.15;P(X = 2) = 0.30;P(X = 3) = 0.20;P(X = 4) = 0.10;P(X = 5) = 0.05;

Hence, since each customer takes 3 minutes to check out, the probability that it will take more than 9 minutes for all the customers currently in line to check out is the probability that there are more than 3 customers, hence:

P(X > 3) = P(X = 4) + P(X = 5) = 0.10 + 0.05 = 0.15.

0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.

find 6 rational numbers between 3 and 4.​

Answers

Answer:

[tex] \frac{3 \times 10}{1 \times 10} [/tex]

And

[tex] \frac{4 \times 10}{1 \times 10} [/tex]

[tex] = \frac{30}{10} \: and \: \frac{40}{10} [/tex]

[tex] \frac{31}{10} \frac{32}{10} \frac{33}{10} \frac{34}{10} \frac{35}{10} \: and \: \frac{36}{10} [/tex]

Step-by-step explanation:

these are the six rational numbers between 3 and 4

Answer:

[tex]\dfrac{37}{12}, \dfrac{19}{6}, \dfrac{13}{4}, \dfrac{10}{3}, \dfrac{41}{12}, \dfrac{7}{2}[/tex]

Step-by-step explanation:

Write 3 and 4 as rational numbers with a common denominator.

Common denominator = common multiple = 12

[tex]\implies 3=\dfrac{3 \times 12}{12}=\dfrac{36}{12}[/tex]

[tex]\implies 4=\dfrac{4 \times 12}{12}=\dfrac{48}{12}[/tex]

Therefore, the rational numbers between them with a denominator of 12 are:

5) Dane makes a budget for her birthday, she plans to
spend 3/36 Cthree misty-sixths) of her budget on a
cake that costs $24.00. How many much is her total
budget for the birthday.

Answers

Answer:

Step-by-step explanation:

She plans to spend 3/36 of her budget on a cake ($24.00).

Because $24.00 is 3/36 of the total budget, you divide 24 by 3/36.

[tex]\frac{24}{1}[/tex]  ÷  [tex]\frac{3}{36}[/tex]

Then, multiply the reciprocal of 3/36, which is 36/3.

= [tex]\frac{24}{1}[/tex]  ×  [tex]\frac{36}{3}[/tex]

= [tex]\frac{864}{3}[/tex] = 288

So, Dane's total budget for the birthday is $288.
