The perimeter of the irregular shape would be 34 cm.

What is the perimeter of any shape?

In geometry, the perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape.

By using the definition of the perimeter we can compute,

Perimeter = 4 + 2 + 2 + 3 + 3 + 6 + 9 + 5

                 = 34 cm.

Hence, the perimeter of the irregular shape would be 34 cm.

Answer: The final value is £1,020

Step-by-step explanation: In order to find the final value, the first step in the process is to multiply 1,200 by 0.15 in order to find out what 15% of 1,200 is. After doing obtaining the answer, which is 180, subtract that from the original answer in order to find out what the final value will be.

The final value is then equal to £1,020

The probability of at least one boy named Jack is (c) 1 - (9/10 x 9/10 x 9/10 x 9/10 x 9/10 x 9/10)

From the question, we have the following parameters that can be used in our computation:

P(Jack) = 1/10

Number of boys = 6

Using the complement rule of probabilities, we have

P(At least one Jack) = 1 - P(No jack)

Where

P(No jack) = (1 - P(Jack))⁶

So, we have

P(No jack) = (1 - 1/10)⁶

Evaluate

P(No jack) = (9/10)⁶

Substitute the known values in the above equation, so, we have the following representation

P(At least one Jack) = 1 - (9/10)⁶

Evaluate

P(At least one Jack) = 1 - (9/10 x 9/10 x 9/10 x 9/10 x 9/10 x 9/10)

Hence, the probability is (c) 1 - (9/10 x 9/10 x 9/10 x 9/10 x 9/10 x 9/10)

1.5i^- 3j^ is the perpendicular vector to the vector 3.0i^+1.5j^

Whenever there is a 90 degree angle between two vectors, they are said to be perpendicular.  Two perpendicular vectors dot product is zero. and dot product is scaler product of 2 vectors.

Let  b = xi^+ yj^ be the perpendicular vector to a vector

and we know that 2 vectors are perpendicular if thier dot product is 0

so it implies that

b.a(dot product) =0

=> (3i^+1.5j^) . (xi^+yj^)=0

=> 3xi^.i^+ 3y i^.j^ +1.5xj^.i^+1.5yj^j^=0

=>3x+1.5y=0  ----(i)

becaus i^.j^=0 and j^.i^0

=> x= 1.5 and y=-3 satisfies equation (i).

so the perpendicular vector is 1.5i^- 3j^

The standard deviation of the sample proportion is 10.

In math standard deviation is defined as the statistical measure of diversity or variability in a data set.

Here we have given that about 19% of young adults have high blood pressure. consider the proportion of people with high blood pressure in random samples of 45 young adults.

And we need to find the the standard deviation of this sample proportion

Let us assume the expected population standard deviation to be 10, and employing t-distribution to estimate sample size, the study would require a sample size of: 44 to estimate a mean with 67% confidence and a precision of 1.5.

Which means that, if you select a random sample of 44 from a population, and determine the mean to be say y, you would be 67% confident that the mean in the population lies somewhere between y - 1.5 and y + 1.5.

What is 2/5 of 15?

Answer:

2/5 of 15 is 6.

Answer:

6

Step-by-step explanation:

The word of  in math refers to multiplication.

We can convert 15 to a fraction as well so we can use them together (15/1).

[tex]\frac{2}{5}[/tex] x [tex]\frac{15}{1}[/tex]

We can then work diagnolly and reduce the 5 and 15 since they are both divisible by 5- this is also known as the GCF or Greatest Common Factor

[tex]\frac{2}{1}[/tex] x [tex]\frac{3}{1}[/tex]

This is the same as 2 x 3 since both numbers divided by 1 are just themselves.

2x3 = 6

The correct answer is 2x = 14; x = 7

Therefore, The correct answer is 2x = 14; x = 7

Answer:

C. 3

Step-by-step explanation:

First, use the distributive property. Multiply 4x and 1 each by 2.

This gives us the equation 50 + 8x - 2 = 72.

Next, subtract 2 from 50 to get 48. Subtract 2 from 2 to cancel it out.

Then, we have 48 + 8x = 72.

Subtract 48 from both sides. This leaves 8x = 24.

Divide both sides by 8 to get x = 3.

Carly will have to attend school for 8 weeks before she takes a total of 24 quizzes.

Step-by-step explanation:

To determine the number of weeks Carly will have to attend school before she takes a total of 24 quizzes, we need to first calculate the proportion of quizzes taken to weeks attended by dividing the number of quizzes taken by the number of weeks attended:

Proportion = Number of quizzes taken / Number of weeks attended

Proportion = 15 quizzes / 5 weeks

Proportion = 3 quizzes / week

Next, we can use this proportion to calculate the number of weeks Carly will have to attend school before she takes 24 quizzes by multiplying the number of quizzes Carly wants to take by the reciprocal of the proportion:

Number of weeks = Number of quizzes / Proportion

Number of weeks = 24 quizzes / 3 quizzes/week

Number of weeks = 8 weeks

Therefore, Carly will have to attend school for 8 weeks before she takes a total of 24 quizzes.

True, If the end index for slicing specifies a location after the end of the alphabet, Python will use the list's length instead.

What is slicing?

In Python, there is a concept of string, list and tuples. Sometimes it is required to access part of those string, list and tuples. This is known as slicing.

In case of slicing, suppose the the end index specifies a position beyond the end of the list, Python will return to the default length of the string. So there will be no error if the end index specifies a position beyond the end of the list.

Answer: D. 3/8

Step-by-step explanation:

The rate of change or slope is rise/run

We see that the y decreases by 9 and the x decreases by 24, so our slope is -9/-24 = 3/8 because negative and negative will be positive.

So the answer is D

Answer:

C. -3/8

Step-by-step explanation:

To find the rate of change is the same as finding the slope. To find the slope between two points you'd use the slope formula, which is y2-y1 over x2-x1.

You'd get -8-1 over -8-16. -8-1 is -9. -8-16 is -24 so you'd get -9/-24.

Because that isn't one of the answer choices you have to simplify it. To simplify it you would divide both numbers by the same number. A common number they both share is 3. So then you'd divide -9 by 3 and you'd divide -24 by 3. -9 divided by 3 is -3. -24 divided by 3 is -8 so you'd get -3/-8. Which should be C. -3/8. Because both numbers are negative the answer should have a negative sign so you'd cross b and d out. And a isn't right because the 8 is supposed to be in the denominator and not in the numerator.

The graph of g is the graph of f translated 3 units right. Option C is the answer

In geometry, a translation is a type of transformation that involves moving a geometric figure from one location to another without changing its size, shape, or orientation.

Remember, in the cartesian plane or graph, the movement in x-axis is either to the left (negative) or right (positive).

Since f(x) = 2x + 1, looking at g(x) = 2(x + 3) + 1, you will notice that 3 is added to the value x. This is a movement in the positive x-axis (right translation) and the translation is by 3 units.

Therefore, the graph of g is the graph of f translated 3 units right
