Answer:

The chance of drawing a yellow marble is 3/14. The chance of drawing a black marble is 6/14, or 3/7. 3/14 * 3/7 = 9/98.

Step-by-step explanation:

answer is 9/98

Answer:

a. 110°

Positive coterminal angle: 110° + 360° = 470°

Negative angles:

b. 145°

Positive coterminal angle: 145° + 360° = 505°

Negative angles:

c. -30°

Positive coterminal angle: -30° + 360° = 330°

Negative angles:

Note: To find coterminal angles, we add or subtract multiples of 360° to the given angle. To find negative coterminal angles, we simply add a negative sign in front of the angle.

The exact values of the given trigonometric functions are:

cos(330) = [tex]\sqrt{3}/2[/tex] or 0.866

sin(330) = 1/2 or 0.5

To find the trigonometric values of cos(330) and sin(330) exactly, we can use the unit circle and the properties of the trigonometric functions.

In the unit circle, the angle of  330 degrees is equivalent to -30 degrees or [tex]-\pi/6[/tex] radians. Since cosine is an even function, we know that [tex]cos(-\theta) = cos(\theta)[/tex], so we can find cos(-30).

Using the special triangles and the reference angle of 30 degrees, we can determine the exact values:

cos(-30) = cos(30) = [tex]\sqrt{3}/2[/tex]

Similarly, the sine of -30 degrees is the same as the sine of 30 degrees:

sin(-30) = sin(30) = 1/2

Therefore, the exact values are:

cos(330) = cos(-30)= cos(30) = [tex]\sqrt{3}/2[/tex] or 0.866

sin(330) = sin(-30)= sin(30)= 1/2 or 0.5

To calculate the confidence interval, we'll use the formula:

CI = sample proportion ± z* (standard error)

where:

- sample proportion = p_hat = 23/50 = 0.46 (proportion of students in the sample who used tutoring and found it beneficial)

- z = 1.96 (for a 95% confidence level)

- standard error = sqrt(p_hat * (1 - p_hat) / n) = sqrt(0.46 * 0.54 / 50) = 0.101

Plugging these values into the formula, we get:

CI = 0.46 ± 1.96 * 0.101

CI = [0.263, 0.657]

Therefore, we can say with 95% confidence that the true proportion of Mesa students who have used tutoring and found it beneficial is between 0.263 and 0.657.

A data set includes 108 body temperatures of healthy adult humans having a mean of 98.2 and a standard deviation of 0.64 .

Now, We have to construct  a 99% confidence interval estimate of the mean body temperature of all healthy humans.

We use these formula for upper limit and lower limit:

u = x + Zα/2 × (s/√n) (For the upper limit)

u = x - Zα/2 × (s/√n) (For the lower limit)

We have the information from question:

x = sample mean = 98.2

s = standard deviation = 0.64

n = sample size = 108.

[tex]Z_\frac{\alpha }{2}[/tex] = critical value for a 2 tailed test performed at a 1% level of significance ( 100% - 99%) = 2.58

Now, Substitute the parameter,

For upper limit:

u = x + Zα/2 × (s/√n)

u = 98.2 + 2.58 ( 0.64/√108)

u = 98.2 + 2.58 ( 0.0616)

u = 98.2 + 0.1589

u = 98.4

For lower limit:

u = x - Zα/2 × (s/√n)

u = 98.2 - 2.58 ( 0.64/√108)

u = 98.2 - 2.58 ( 0.0616)

u = 98.2 - 0.1589

Step-by-step explanation:

1kg of prawn costs $18.

Let's use algebra to determine how much 1 kg of prawns would cost.

We know that 3kg of fish cost $12, so the cost per kg of fish is:

$12 ÷ 3kg = $4/kg

We can set up an equation since we also know that the combined cost of 3 kg of fish and 1 kg of prawn is $30:

3($4/kg) + 1($x/kg) = $30

Simplifying the left side of the equation, we get:

$12/kg + $x/kg = $30

Subtracting $12/kg from both sides, we get:

$x/kg = $18

Therefore, 1kg of prawn costs $18.

Answer:

The number of times the coin landed on heads is 32 - 8 = 24 since there were 32 flips in total and 8 of them resulted in tails.

The ratio of heads outcomes to tails outcomes can be expressed as 24:8. To simplify this ratio, we can divide both the numerator and denominator by their greatest common factor, which is 8.

So, 24/8 = 3 and 8/8 = 1. Therefore, the ratio of heads outcomes to tails outcomes in simplified form is 3:1.

The measure of angles m∠1,m∠2, and m∠3 are 133°, 47°, and 43° respectively

47° and m∠1 are on a straight line and their sum is equal to 180° so;

m∠1 + 47° = 180° {sum of angles on a straight line}

m∠1 = 180° - 47° {subtract 47° from both sides}

m∠1 = 133°

47° and m∠2 are vertical angles hence they are equal so;

m∠2 = 47°

m∠2 and m∠3 are complementary angles so their sum is equal to 90°

m∠3 + 47° = 90°

m∠3 = 90° - 47°

m∠3 = 43°

Tara would be required to repay the debt in 90.42 days, or roughly 90 days and 10 hours.

The simple interest is calculated as,

Simple interest = Principal x Rate x Time

Where the loan's principal, interest rate, and term are represented by the variables principal, rate, and time, respectively.

In this case, the maturity value, which includes the principal and interest, is $2,572.92 and the principal is $2,500. The rate is 8.75%. Let's begin by computing the interest on the loan:-

Interest = Maturity value - Principal

Interest = $2,572.92 - $2,500

Interest = $72.92

Calculate the interest below,

Interest = Principal x Rate x Time / 365

$72.92 = $2,500 x 0.0875 x Time / 365

$72.92 x 365 = $2,500 x 0.0875 x Time

Time = $72.92 x 365 / ($2,500 x 0.0875)

To find the surface area of the figure, we need to break it down into its component shapes and calculate their surface areas, then add them up.

The figure can be divided into a rectangular prism (the bottom part) and two triangular prisms (the top part).

The rectangular prism has dimensions 32 m × 26 m × 12 m. Its surface area is:

2(32 × 26) + 2(32 × 12) + 2(26 × 12) = 2(832 + 384 + 312) = 2(1528) = 3056 m²

Each of the two triangular prisms has base 32 m, height 15 m, and slant height 17 m (using the Pythagorean theorem). The surface area of each triangular prism is:

2(1/2)(32)(15) + 2(1/2)(32)(17) + 2(1/2)(15)(17) = 480 + 544 + 255 = 1279 m²

Therefore, the total surface area of the figure is:

3056 + 1279 + 1279 = 5614 m²

Rounding to the nearest tenth, the surface area is 5614.0 m².

Answer:

4/3 × (4 5/6 - 1/2) is greater.

Step-by-step explanation:

What is inside the parenthesis is the same in both expressions. So what makes them different is multiplying by 3/4 or by 4/3.

Multiplying by 3/4 will make the value smaller. It is essentially "a shrink" multiplier.

On the other hand, 4/3 is bigger than one. If you times something by 1 it stays the same. If you multiply by something greater than 1 the answer will be bigger than the starting number.

Since these are actual numbers, we can just do it.

3/4(4 5/6 - 1/2)

= 3/4(4 5/6 - 3/6)

= 3/4(4 2/6)

= 3/4(4 1/3)

= 3/4(13/3)

= 13/4

= 3.25

4/3(4 5/6 - 1/2)

= 4/3(4 5/6 - 3/6)

= 4/3(4 2/6)

= 4/3(4 1/3)

The trigonometric identity sin(x + y) = (√95 + 3√17)/27

Trigonometric identities are identities containing trigonometric ratios.

Given that tanx = 1/√8 and siny = √17/6 and angles x and y are both in Quadrant 1, we need to find the value of sin(x + y)

So, using the trigonometric identity sin(x + y) = sinxcosy + cosxsiny

First we need to find sinx, cos x and cosy

Using trigonometric identity 1 + tan²x = sec²x

sec²x = 1 + tan²x

= 1 + (1/√8)²

= 1 + 1/8

= (8 + 1)/8

= 9/8

sec²x = 9/8

secx = √(9/8)

= ±3/2

secx = 1/cosx

1/cosx = ±3/2

cosx = ±2/3

Now sinx = √(1 - cos²x)

= √(1 - (2/3)²)

= √[(1 - 4/9)]

= √[(9 - 4)/9]

= √(5/9)

= ±√5/3

Also, cosy = √(1 - sin²y)

= √(1 - (√17/6)²)

= √(1 - 17/36)

= √[(36 - 17)/36]

= √(19/36)

= ±√19/6

Since sin(x + y) = sinxcosy + cosxsiny, substituting the positive values of the variables into the equation since they are in the first quadrant, we have that

sin(x + y) = sinxcosy + cosxsiny

sin(x + y) = √5/3 × √19/6 + 2/3 × √17/6

= √95/27 + √17/9

= √95/27 + √17/9

= 1/9(√95/3 + √17)

= 1/9(√95 + 3√17)/3

= (√95 + 3√17)/27

So, sin(x + y) = (√95 + 3√17)/27

Let's start by trying out different combinations and see if they give us a rectangle:

- If we use the two 4 ft sections as the width, we have 8 ft. For the length, we can use one of the 6 ft sections, which gives us a length of 6 ft. However, we still have a 6 ft section left that we cannot use to complete the rectangle. This combination doesn't work.

- If we use the two 6 ft sections as the width, we have 12 ft. For the length, we can use one of the 4 ft sections, which gives us a length of 4 ft. However, we still have an 8 ft section left that we cannot use to complete the rectangle. This combination doesn't work.

- If we use the 8 ft section as the width, we have 8 ft. For the length, we need to use both 6 ft sections, which gives us a length of 12 ft. We used all sections and we have a rectangle. This combination works.

Therefore, Patty's garden could be 8 ft by 12 ft.
