Answer:

$7.43

Step-by-step explanation:

f (fries) = 1.01

d (drinks) = 1.07

1.05f + 1.07d = ?

To solve this problem, you need to replace the variable with the amount of each item.

1.05(3) + 1.07(4) = ?

Now we can solve by multiplying and adding:

A weighted (unfair) die that was purchased at a magic shop was rolled 30 times. The die landed on five dots 25 times. Based on the results, what is the margin of error for the true proportion of times this die would land on five dots? Base your margin of error on a 95% confidence level.

Answers

Using the z-distribution, it is found that the margin of error for the true proportion of times this die would land on five dots is of 0.1338.

What is a confidence interval of proportions?

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The estimate and the sample size are given as follows:

[tex]\pi = \frac{25}{30} = 0.8333, n = 30[/tex].

Hence the margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]M = 1.96\sqrt{\frac{0.8333(0.1667)}{30}}[/tex]

M = 0.1338.

The Fundamental Principle of Counting states that we can find the total number of ways that two or more separate tasks can happen by multiplying the number of ways each task can happen separately.

No. of ways = 2⁵ = 32

No. of ways = 4 x 3 = 12 ways

An angle measures 150.8° more than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

14.6°, 165.4°

Step-by-step explanation:

We can say that x is the supplementary angle and x + 150.8 is the other angle

Supplementary angles add up to 180°

x + x + 150.8 = 180

2x = 29.2

x = 14.6 | we found one of the angles

x + 150.8 = 165.4 | find the other angle

A right triangle has one 28° and one 90°. What is the measurement of the third angle?

Answers

Answer:

The third measurement is 62°

Step-by-step explanation:

Hey there! Please take a look at the explanation for clear understanding to the answer and also let me know in comment if you have any doubts!

Euclidean Triangle

The theorem regarding it states that, sum of all 3 interior angles must equal to 180°.

That means, we will have this equation:

[tex]\displaystyle \large{28^{\circ} + 90^{\circ} + x=180^{\circ}}[/tex] because we know two interior angles and one missing angle - sum of them equals to 180 degrees.

Then we solve for x-term to find the third measurement!

[tex]\displaystyle \large{118^{\circ}+x=180^{\circ}}[/tex]

Subtract both sides by 118 degrees.

[tex]\displaystyle \large{118^{\circ}-118^{\circ}+x=180^{\circ}-118^{\circ}}\\\\\displaystyle \large{x=62^{\circ}}[/tex]

Henceforth, the third measurement is 62°

The area of the rectangle ACEG is the amount of space on it, and the area of square HJFG is 9 square units

How to determine the area of the figures?

The area of a rectangle is:

Area = Length * Width

The area of a square is:

Area = Length * Length

From the question, the given parameters are:

AB =AH = x ;

BC=5;

HG=3

This means that the area of square HJFG is:

Area = HG * HG

Area = 3 * 3

Area = 9

PLEASE HELP WILL GIVE BRAINIEST HELPPP!!!!

Answers

Answer:

a. <B = 53°

b. BC = 14

c. x = 14

Step-by-step explanation:

Sine(theta) = Opp/HypCosine(theta) = Adj/HypTan(theta) = Opp/Adj

a. <B = ?

Use Sine.

Sine(<B) = 12 /15

<B = Sin^-1(12/15)

<B = 53.13

<B = 53°

b. BC = ?

Either use Sine(<A) = BC/16 or Cosine(<C) = BC/16

Will be using Cosine.

Cosine(<C) = BC/16

Cosine(30°) = BC/16

BC = 16 * Cos(30°)

BC = 13.856...

BC = 14

c. x = ?

Looking at the triangle. The triangle is isosceles which mean two side angle or side length are the same.

x = 14

Answer:

A: 53.13

B:13.86

C: 14

Step-by-step explanation:

A can be found by using the trigonometric ratio Sin.

Sin=

[tex] \frac{opp}{hyp} [/tex]

And we have our opposite side and hypotenuse. so insert it:

Sin=12/15

Therefore use sin inverse and input that fraction

[tex]sin { }^{ - 1} ( \frac{12}{15} )[/tex]

=53.13010235

Rounded off to two decimals

=53. 13

B can be found using sin again. Since we know that Sin is opp/hyp and we have the hyp, we are now looking for the opp.

So use Sin(60)=BC/16

Multiply 16 on both sides to get: 16Sin(30)=BC

13.85640646=BC

rounded off to two decimals:

13.86

C can be found using Tan. Tan is opp/adjacent

We have the adjacent and we are looking for the opposite.

So use:

tan(45)=X/14

Multiply 14 on both sides

14tan(45)=X

14=X
