Information from the question

right angle triangle

The values of the variables is worked using SOH CAH TOA

The right angle triangle of sides as described below

hypotenuse = k

opposite = n

adjacent = 6

The variable n is solved using tan, TOA, the angle is 30

tan 30 = Opposite / Adjacent

tan 30 = n / 6

tan 30 * 6 = n

n = 2√3

The variable k is solved using cos, CAH, the angle is 30

cos 30 = Adjacent / Hypotenuse

cos 30 = 6 / k

k = 6 / cos 30

k = 4√3

There were 500 times more views were on Saturday than Sunday

In this question, we have been given a website got 4 × 10^9 views on Saturday and 8 × 10^6 views on Sunday.

We need to find the number of times more views were on Saturday than Sunday.

We need to divide 4 × 10^9 by 8 × 10^6

( 4 × 10^9) / (8 × 10^6)

= (4/8) * 10^(9 - 6)                   ..............(rule of exponents)

⇒ Supplementary angles are angles that add up to 180°

⇒ ∠1+∠2=180°(angles on a straight line)

∠2=∠4( Corresponding angles are equal m||n)

⇒*NOTE THE FOLLOWING STATEMENT IS TO MAKE YOU UNDERSTAND,IT MUST NOT BE INCLUDED IN YOUR ANSWERBOOK)

If ∠2=∠4

in the place of ∠2 in the equation ∠1+∠2=180° we can substitute ∠4 since the two angles (∠2 and ∠4) are equal by corresponding angles

______________________________________________________

⇒You may include this step now as you now know how ∠4 came up.

∴∠1+(∠4)=180°

∠1+∠4=180°

Now from the above equation we can see that ∠1 and ∠4 are supplementary angles as they both add up to 180°

Answer:

8×2+8×g

Step-by-step explanation:

The fraction in their simplest form will be:

9. 12/15 = 4/5

10. 6/8 = 3/4

11. 25 / 100 = 1/4

12. 5 / 40 = 1/8

13. 7/77 = 1 / 11

14. 4 / 36 = 1/9

15. 18/20 = 9/10

16. 100/1000 = 1/10

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split.

It should be noted that in order to divide a fraction in their simplest form, the equivalent numbers must be used.

For example, 100/1000 will be:

(100 ÷ 100) / (1000 ÷ 100)

= 1 / 10

25 / 100 has a common factor of 25 as.this gives 1/4.

If a man is 6 feet 2 inches tall, his z-score is equal to 1.82.

If a woman is 5 feet 10 inches tall, her z-score is equal to 2.92.

The 5 feet 10 inches American woman is relatively taller.

In a normal distribution, the z-score of a given sample score can be calculated by using this formula:

Z-score = (x - μ)/σ

Where:

Next, we would convert the height in feet to inches as follows:

American man = 6 × 12 + 2 = 74 inches.

American woman = 5 × 12 + 10 = 70 inches.

For the American man's z-score, we have:

Z-score = (74 - 69.2)/2.64

Z-score = 4.8/2.64

Z-score = 1.82

For the American woman's z-score, we have:

Z-score = (70 - 64.2)/2.53

Z-score = 5.8/2.53

Z-score = 2.92

Therefore, the 5 feet 10 inches American woman is relatively taller because she has a higher z-score (2.92 > 1.82).

According to the scatter plot provided, the weight for someone who is 1.5 meters tall is predicted to be 45.45 kilograms.

A line of best fit is also referred to as a trend line and it can be defined as a statistical and analytical tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between a data.

In this scenario, the weight (in kilogram) would be plotted on the y-axis of the scatter plot while the height (M) would be plotted on the x-axis of the scatter plot.

From the scatter plot (see attachment) which models the relationship between data points in the table, a linear function for the line of best fit is given by:

Weight, kg = -114.3 + 106.5M

When M = 1.5 meters, we have:

Weight, kg = -114.3 + 106.5(1.5)

Weight, kg = -114.3 + 159.75

Weight, kg = 45.45 kg.

The dimensions of this rectangular tank that has the minimum surface area are 42 feet and 21 feet.

First of all, we would determine the surface area of this rectangular tank with a square​ base by using this formula:

h = V/s²

Where:

For the surface area of this rectangular tank with a square​ base, we have:

Surface area, A = base area + 4(lateral area)

Surface area, A = s² + 4(s × h)

Surface area, A = s² + 4(s × V/s²)

Surface area, A = s² + 4V/s

Next, we would take the first derivative of the surface area as follows:

A' = 2s - 4V/s²

Substituting the given parameters into the formula, we have;

A' = 2s - 4(37044)/s²

For the minimum surface area dimension, the first derivative of the surface area would be equated to zero:

2s - 148,176/s² = 0

148,176/s² = 2s

148,176 = 2s³

s³ = 74,088

s = ∛74,088

s = 42 feet.

For the height, we have:

Height, h = V/s²

Height, h = 37044/42²

Height, h = 37044/1764

The expression that is equivalent to (f × g²) + 5 - (g² × f) is 5

The expression whose equivalence is to be determined is given as

(f × g²) + 5 - (g² × f)

To start with, we need to remove the brackets in the expression

So, we have the following representation

(f × g²) + 5 - (g² × f) = f × g² + 5 - g² × f

Evaluate the products

This gives

(f × g²) + 5 - (g² × f) = fg² + 5 - fg²

Next, we collect the like terms

So, we have

(f × g²) + 5 - (g² × f) = fg²  - fg² + 5

Lastly, we evaluate the like terms

So, we have

(f × g²) + 5 - (g² × f) = 5

The above expression cannot  be further simplified

Hence, the equivalent expression is 5

a) The 90% confidence interval of the percentage of all mangoes on the truck that fail to meet the standards is: (7.55%, 12.45%).

b) The margin of error is: 2.45%.

c) The 90% confidence is the level of confidence that the true population percentage is in the interval.

d) The needed sample size is: 271.

A confidence interval of proportions has the bounds given by the rule presented as follows:

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

The margin of error is given by:

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

The variables are listed as follows:

The confidence level is of 90%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.90}{2} = 0.95[/tex], so the critical value is z = 1.645.

The sample size and the estimate are given as follows:

[tex]n = 150, \pi = \frac{15}{150} = 0.1[/tex]

The margin of error is of:

[tex]M = z\sqrt{\frac{0.1(0.9)}{150}} = 0.0245 = 2.45\%[/tex]

The interval is given by the estimate plus/minus the margin of error, hence:

For a margin of error of 3% = 0.03, the needed sample size is obtained as follows:

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

[tex]0.03 = 1.645\sqrt{\frac{0.1(0.9)}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.645\sqrt{0.1(0.9)}[/tex]

[tex]\sqrt{n} = \frac{1.645\sqrt{0.1(0.9)}}{0.03}[/tex]

[tex](\sqrt{n}})^2 = \left(\frac{1.645\sqrt{0.1(0.9)}}{0.03}\right)^2[/tex]
