Answer

Their combined score is 331 points

Explanation

Determine each person's score

Collin score: 139

Brian: 139 + 53 = 192

Add the scores together

139 + 192 = 331

Colin scored 139 points and Brian scored 53 points more than Colin, which is 192 points. Adding Colin's and Brian's scores gives a combined score of 331 points.

In the game of darts, Colin and Brian scored different points. We know that Colin scored 139 points. As per the information given, Brian scored 53 points more than Colin. So, to find out how many points Brian scored, we can add 53 to Colin's score of 139, which gives us 192 points for Brian.

To find out the combined score of Colin and Brian, we simply add Colin's score to Brian's score. So, 139 (Colin's score) plus 192 (Brian's score) equals 331.

Therefore, the combined score of Colin and Brian is 331 points.

Answer:

What is the probability of getting a vowel (a success) for the spinner shown?

✔ 1/3

Suppose you spin the spinner 5 times.

✔ P(3 successes) means “the probability of getting a vowel on exactly 3 of the spins.”

Step-by-step explanation:

edg 2020

Using the binomial distribution, it is found that:

For each spin, there are only two possible outcomes, either it is a vowel, or it is not. The result of a spin is independent of any other spin, hence the binomial distribution is used to solve this question.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability of 3 successes is given by:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{5,3}.(0.3333)^{3}.(0.6667)^{2} = 0.1646[/tex]

Answer:

To find perimeter, you must add length plus length plus width plus width.

(L+L+W+W)

the length is 5, and the width is 8. since there are 4 sides, we must add 5+5+8+8, and that equals 26.

As we know the formula for finding the perimeter of a rectangle is:

[tex]Perimeter=2(L+B)[/tex]

here, L is the length of the rectangle and B is the breadth of the rectangle.

As the values of the length and breadth are given, we will put in the formula;

[tex]Perimeter=2(8+5)[/tex]

[tex]Perimeter=2(13)[/tex]

[tex]Perimeter=26[/tex]

Hence, the perimeter of the rectangle is 26 units.

Perimeter is the distance around the edge of a shape.

The total length of the boundary of a closed shape is called its perimeter. Hence, the perimeter of that shape is measured as the sum of all the sides. Thus, the perimeter formula is Perimeter(P) = Sum of all the sides.

Any equation expressed in terms of parameters is a parametric equation. The general equation of a straight line in slope-intercept form, y = mx + b, in which m and b are parameters, is an example of a parametric equation.

Answer:

P =26%

Step-by-step explanation:

In this problem we have the ages of all new employees hired during the last 10 years of normally distributed.

We know that the mean is [tex]\mu = 35[/tex] years and standard deviation is [tex]\sigma = 10[/tex] years

By definition we know that if we take a sample of size n of a population with normal distribution, then the sample will also have a normal distribution with a mean

[tex]\mu_m = \mu[/tex]

And with standard deviation

[tex]\sigma_m = \frac{\sigma}{\sqrt{n}}[/tex]

Then the average of the sample will be

[tex]\mu_m = 35\ years[/tex]

And the standard deviation of the sample will be

[tex]\sigma_m =\frac{10}{\sqrt{10}} = 3.1622[/tex]

Now we look for the probability that the mean of the sample is greater than or equal to 37.

This is

[tex]P({\displaystyle{\overline {x}}}\geq 37)[/tex]

To find this probability we find the Z-score

[tex]Z = \frac{{\displaystyle{\overline{x}}} -\mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]Z = \frac{37 -35}{\frac{10}{\sqrt{10}}} = 0.63[/tex]

So

[tex]P({\displaystyle{\overline {x}}}\geq 37) = P(\frac{{\displaystyle{\overline {x}}}-\mu}{\frac{\sigma}{\sqrt{n}}}\geq\frac{37-35}{\frac{10}{\sqrt{10}}}) = P(Z\geq0.63)[/tex]

We know that

[tex]P(Z\geq0.63)=1-P(Z<0.63)[/tex]

Looking in the normal table we have:

[tex]P(Z\geq0.63)=1-0.736\\\\P(Z\geq0.63) = 0.264[/tex]

Finally P = 26%

To find the probability that the sample mean age of 10 employees is at least 37, we can use the Central Limit Theorem and standardize the sample mean. The probability is approximately 2.28%.

To solve this problem, we need to use the Central Limit Theorem, which states that the sample mean of a large enough sample size will be approximately normally distributed regardless of the shape of the population distribution.

In this case, the mean age of new employees is normally distributed with a mean of 35 and a standard deviation of 10. We want to find the probability that the sample mean age of 10 employees is at least 37.

To find this probability, we first need to standardize the sample mean using the formula z = (x - μ) / (σ / sqrt(n)), where x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

Using this formula, we have z = (37 - 35) / (10 / sqrt(10)) = 2 * sqrt(10).

From a standard normal distribution table, we can find that the probability of getting a z-score less than 2 * sqrt(10) is approximately 1 - 0.0228 = 0.9772. However, we want the probability of getting a sample mean at least 37, so we subtract this probability from 1 to get 1 - 0.9772 ≈ 0.0228.

Therefore, the probability that the sample mean age of 10 employees will be at least 37 is approximately 2.28%.

Answer:

x ≤ - 4

Step-by-step explanation:

Given

3 - x ≥ 2x + 15 ( add x to both sides )

3 ≥ 3x + 15 ( subtract 15 from both sides )

- 12 ≥ 3x ( divide both sides by 3 )

- 4 ≥ x, hence

x ≤ - 4

3 - x is greater than equal to 2 X + 15

3 is greater than equal to 3X + 15

- 12 is greater than equal to 3 x

- 4 is greater than equal to x

hence x b - 4 - 4 is greater than x

Answer:

The ninth term is -0.75.

Step-by-step explanation:

Let's write the actual formula for this arith. seq.

It will have the general form a(n) = a(1) + (n-1)d, where a(1) is the first term, n is the term counter (1, 2, 3, .... ) and d is the common difference.

Here, a(n) = -2.75 + (n - 1)(0.25)

So the ninth term of this sequence is

a(9) = -2.75 + (9 - 1)(0.25

      = -2.75 + 8(0.25)

      = -2.75 + 2

       = -0.75

The ninth term is -0.75.

Answer:

[tex]a_9=-0.75[/tex]

Step-by-step explanation:

The given sequence has the first term, [tex]a_1=-2.75[/tex] and d=0.25

The general formula for an arithmetic sequence is given by;

[tex]a_n=a_1+d(n-1)[/tex]

Since we want to find [tex]a_9[/tex], it means n=9

We substitute the given values into the formula to obtain;

[tex]a_9=-2.75+0.25(9-1)[/tex]

[tex]a_9=-2.75+0.25(8)=-0.75[/tex]

Hence, the 9th term is

[tex]a_9=-0.75[/tex]

Area is the amount of space that a two-dimensional shape takes up. It is measured in square units, such as square feet (ft^2), square yards (yd^2), or square meters (m^2).

To calculate the area of a rectangle, multiply the length by the width.

Area of a rectangle = length * width

To calculate the area of a square, multiply the side length by itself.

Area of a square = side length * side length

To calculate the area of a triangle, multiply the base by the height and divide by 2.

Area of a triangle = base * height / 2

Perimeter is the total length of all the sides of a two-dimensional shape. It is measured in linear units, such as feet (ft), yards (yd), or meters (m).

To calculate the perimeter of a shape, add up the lengths of all the sides.

Perimeter of a shape = sum of the lengths of all the sides

Example:

To calculate the area and perimeter of the rectangle in question #4, we would use the following formulas:

Area = length * width = 5 yd * 72 yd = 360 yd^2

Perimeter = sum of the lengths of all the sides = 5 yd + 72 yd + 5 yd + 72 yd = 30 yd

Answer:

h = 47.70 ft

The antenna is 47.70 ft tall.

Step-by-step explanation:

The height of the antenna is approximately 47.4ft when calculated using the Pythagorean theorem: √((50ft)^2 - (15ft)^2).

The question is asking for the height of the antenna. We can solve this problem by using the Pythagorean theorem, which states that in a right triangle the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Here, the hypotenuse is the length of the cable (50 ft), one side is the distance from the base of the antenna to the anchor point (15 ft) and the other side (which we are trying to find), is the height of the antenna.

According to the Pythagorean theorem, the height of the antenna can be calculated as follows: Height = √(Hypotenuse^2 - Base^2), which translates into Height = √((50ft)^2 - (15ft)^2). When you calculate that you get the height of the antenna as approximately 47.4 feet, rounded to the nearest tenth.

Answer:

the required equation is:

[tex]x^2 -10 +34[/tex]

Step-by-step explanation:

The equation given is:

[tex]x^2 -()+34[/tex]

Comparing it with standard quadratic equation

[tex]a^2 +bx+c[/tex]

a= 1,

b=?

C= 34

We can find the value of b using Vieta's formulas :

That states that if roots x₁ and x₂ are given then,

x₁ + x₂ = -b/a

We are given roots: 5 ± 3i i.e, x₁= 5 + 3i and x₂= 5 - 3i

solving

5 + 3i + 5 - 3i = -b/1

10 = -b

Since the given equation already gives b as -b so, -b= 10 => b=10

Putting value of b in the missing place the required equation will be:

[tex]x^2 -10 +34[/tex]

To find the missing term in a quadratic equation given complex roots, use the properties of conjugate roots to determine the term.

Since the roots are in the form of a complex number, they are conjugates of each other, which helps in finding the missing term.

Given roots: 5 ± 3i

Using the sum and product of roots formula

Sum: (5 + 3i) + (5 - 3i) = 10. Product: (5 + 3i)*(5 - 3i) = 34

Construct the equation: x2 - (10x) + 34 = 0

Answer:

[tex]sin(t) =\frac{\sqrt{7}}{4}[/tex]

Step-by-step explanation:

By definition we know that

[tex]sec(t) = \frac{1}{cos(t)}[/tex]

and

[tex]cos ^ 2(t) = 1-sin ^ 2(t)[/tex]

As [tex]sec(t) = -\frac{4}{3}[/tex]

Then

[tex]sec(t) = -\frac{4}{3}\\\\\frac{1}{cos(t)} =-\frac{4}{3}\\\\cos(t) = -\frac{3}{4}[/tex]

Now square both sides of the equation:

[tex]cos^2(t) = (-\frac{3}{4})^2[/tex]

[tex]cos^2(t) = \frac{9}{16}\\\\[/tex]

[tex]1-sin^2(t) =\frac{9}{16}\\\\sin^2(t) =1-\frac{9}{16}\\\\sin^2(t) =\frac{7}{16}\\\\sin(t) =\±\sqrt{\frac{7}{16}}[/tex]

In the second quadrant sin (t) is positive. Then we take the positive root

[tex]sin(t) =\sqrt{\frac{7}{16}}[/tex]

[tex]sin(t) =\frac{\sqrt{7}}{4}[/tex]

The value of sin(t) = √7/4 because sine is positive in Quadrant II.

First, recall that sec(t) is the reciprocal of cos(t):

sec(t) = 1/cos(t)

Given: sec(t) = -4/3, so:

cos(t) = -3/4

Since angle t lies in Quadrant II, cosine is negative, and sine is positive. Use the Pythagorean identity:

sin²(t) + cos²(t) = 1

Substitute cos(t):

sin²(t) + (-3/4)² = 1

sin²(t) + 9/16 = 1

Solve for sin²(t):

sin²(t) = 1 - 9/16

sin²(t) = 16/16 - 9/16

sin²(t) = 7/16

Take the square root of both sides:

sin(t) = √(7/16) = √7/4

Since we are in Quadrant II, sine is positive:

sin(t) = √7/4

She is 4 years an d3 months old

Answer:

111 months

Step-by-step explanation:

First, look at how many whole years old Emma is. Emma is 9 whole years old. 1 year consists of 12 months. So, multiply 9 [years] by 12 [months] to get 108. The number 108 is how many months are in 9 years. However, Emma is 9 months and 1/4 years old.

To find out how many months 1/4 of a year is, multiply 1/4 [year] by 12 [months] . 12 is the same as 12/1, so multiply the numerators and denominators of 1/4 and 12/1

1 x 12 = 12

4 x 1 = 4

12/4 = 3

Therefore, 1/4 year is 3 months. Now, add 108 months and 3 months to get 111 months. Therefore, Emma is 111 months old.
