300/4 = 75

Multiply this by 5

75 x 5 = 375

Add the two values together

Step-by-step explanation:

Number of boys=300

Ratio of boys to girls=4:5

let the number of girls=y

300/y=4/5

Cross multiply

300×5=4×y

1500=4y

Divide through both sides by 4

1500/4=4y/4

374=y

Number of girls is 375

Total number of students=Number of boys+Number of girls

Total number of students=300+375

Total number of students=375

Step-by-step explanation:

In a simple linear regression model , if we change the input variable by 1 unit , output variable will change by its slope.

What is linear regression?

According on the value of another variable, a variable's value can be predicted using a linear regression analysis. The dependent variable is the one you're trying to forecast. The term "independent variable" refers to the variable you are using to forecast the value of the other variable.

Main Body:

For linear regression

Y=a + bx + error

If we neglect error

then Y=a + bx.

If x increases by 1

then Y = a +b(x+1) which implies

Y=a + bx + b.

So Y increases by its slope.

Hence their is an increase in the slope in y.

In linear regression, one variable, called a dependent variable, is related to one or more independent variables by a linear equation.

A function has the following format: y = f(x).

In which each value of y is a function of one value of x, and thus, x is the independent variable and y is the dependent variable.

That is, the input of the function is the independent variable and the output is the dependent variable.

In the case of multiple inputs, all the inputs are independent variables.

Answer:

the crew has a greater median

the cross country has a grearer standard deviation  

Explanation:

Median

for the cross country thr median is located at the second line of the box plot or its Q2 and it is apprx. 75

for the crew, we count the dot bith sides going to middle part and it is apprx. 93

thus,  

the crew has a greater median

Standard deviation

for cross country we got the formula to estimate its standard deviation

we got

S = 3/4(Q2-Q1)

S = 3/4(120-55)

S = 48.75

for crew we dont have any formula, but using only visual analization we can see that the value of data is super close to each other, meaning its sd will be close to its mean thus it has a smaller sd  

thus

the cross country has a grearer standard deviation

Answer: 227

Step-by-step explanation:

To find the 46th term of the sequence, we need to first determine the pattern of the sequence. We can see that the sequence increases by 5 between each consecutive term. Therefore, the common difference of the sequence is 5.

Using this information, we can find the \(n\)th term of the sequence using the formula:

\(\Large \boxed{an = a1 + d(n-1)}\)

where

Using the given terms, we have:

To find the 46th term, we substitute \(n = 46\) into the formula:

Therefore, the 46th term of the sequence is 227.

________________________________________________________

To find the pattern in the sequence, we can observe that each term is obtained by adding 5 to the previous term. Therefore, we can write the recursive formula for the sequence as:

\(\large a_1 = 2\)

\(\large a_n = a_{n-1} + 5\)

To find the 46th term, we can use the recursive formula to generate each term until we reach the desired term:

\(\large a_1 = 2\)

\(\large a_2 = a_1 + 5 = 2 + 5 = 7\)

\(\large a_3 = a_2 + 5 = 7 + 5 = 12\)

\(\large a_4 = a_3 + 5 = 12 + 5 = 17\)

\(\vdots\)

\(\large a_{46} = a_{45} + 5 \approx \boxed{227}\)

\(\therefore\) The 46th term of the sequence is approximately 227.

We can also write the explicit formula for the sequence as:

\(\large a_n = 5n - 3\)

To verify that this formula generates the same sequence as the recursive formula, we can substitute the value of n = 1, 2, 3, etc. and compare the results.

The dimensions of the rectangular poster are 9 inches by 22 inches.

Let's assume the width of the rectangular poster is x inches.

According to the given information, the length of the poster is 4 more inches than two times its width. So, the length can be expressed as 2x + 4 inches.

The formula for the area of a rectangle is length × width. In this case, the area is given as 198 square inches.

Therefore, we have the equation:

(2x + 4) × x = 198

Expanding the equation:

\(2x^2 + 4x = 198\)

Rearranging the equation to standard quadratic form:

\(2x^2 + 4x - 198 = 0\)

To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. Let's use the quadratic formula:

x = (-b ± √\((b^2 - 4ac\))) / (2a)

Plugging in the values:

x = (-4 ± √\((4^2 - 4(2)(-198)))\) / (2(2))

x = (-4 ± √(16 + 1584)) / 4

x = (-4 ± √1600) / 4

x = (-4 ± 40) / 4

Simplifying:

x = (-4 + 40) / 4 = 9

x = (-4 - 40) / 4 = -11

Since we are dealing with dimensions, the width cannot be negative. Therefore, the width of the poster is 9 inches.

Substituting the value of x back into the length equation:

Length = 2x + 4 = 2(9) + 4 = 18 + 4 = 22 inches

The result for the negative square root of  \(\frac{-25}{36}\) is  \(\frac{5}{6}i\).

A complex number is represented by the following form: a+bi, where a and b are real numbers.  The variables: a is the real part and bi imaginary part. See an example: 5 + 2i , then: 5 represents the real part and  2i represents the imaginary part.

Regarding operations math, the same properties used for real numbers can be applied to complex numbers. And for solving the operations math with these numbers, it is important to know that i²= -1, consequently \(\sqrt{-1} =i\). Thus, 2i² = 2*(-1)= -2.

Thus, to find the negative square root of -25/36. You should write:

\(\sqrt{-\frac{25}{36} }\), knowing that \(\sqrt{25}\)=5 and \(\sqrt{36} =6\). Thus,

\(\sqrt{-\frac{25}{36} }\)=\(\frac{5}{6} *\sqrt{-1}\), like  \(\sqrt{-\frac{25}{36} }\)=\(\frac{5}{6} *\sqrt{-1}\), you have:

\(\sqrt{-\frac{25}{36} }\)=\(\frac{5}{6}\)*i

Answer:

Step-by-step explanation:

(x) = 7 - 2x

Let t(x) =0

0 = 7-2x

Subtract 7 from each side

-7 = -2x

Divide by -2

-7/-2 =-2x/-2

7/2 =x

h(x) = 4x + 2

Replace x with x+3

h(x+3) = 4(x+3) + 2

Distribute

            = 4x+12 +2

            =4x+14

Answer:

19) \(x=\frac{7}{2}\)

20) \(h(x+3)=4x+14\)

Step-by-step explanation:

19)

We have the function:

\(t(x)=7-2x\)

And we want to find x such that t(x)=0.

So, substitute 0 for t(x):

\(0=7-2x\)

Solve for x. Subtract 7 from both sides:

\(-7=-2x\)

Divide both sides by -2:

\(\frac{7}{2}=x\)

Flip:

\(x=\frac{7}{2}\)

20)

We have:

\(h(x)=4x+2\)

To find h(x+3), substitute (x+3) for x. This yields:

\(h(x+3)=4(x+3)+2\)

Multiply:

\(h(x+3)=4x+12+2\)

Add:

\(h(x+3)=4x+14\)

And we're done!

The true statement is that the probability of of selecting a purple paper clip is 7 / 25 and the probability of selecting a paper clip that is not purple is 18 / 25

Probability means possibility. It deals with the occurrence of a random event. Mathematically,

p(A) = number of favourable outcome to A / total number of possible outcomes.

Therefore,

number of pink paper clips = 8

number of purple paper clips = 14

number of yellow paper clips = 12

number of blue paper clips = 16

Therefore,

total number of possible outcome = 8 + 14 + 12 + 16 = 50

Therefore,

The probability of selecting a purple paper clip = 14 / 50 = 7 /25

The probability of selecting a paper clip that is not purple = 1 - 7 /25 = 18 / 25

The only value of x for which f(x) = 0 is x = 36. So, f(x) = -x + 36 does not have a real root, since there is no value of x that makes the function equal to zero.

What is a function ?

A function is a mathematical concept that describes the relationship between a set of inputs (domain) and a set of outputs (range), such that each input has a unique output. In other words, it is a rule that assigns to each input exactly one output.

A real root of a function refers to a value of x for which the value of the function is equal to zero. So, to determine whether f(x) = -x + 36 has a real root, we need to find the value(s) of x for which f(x) = 0.

Setting f(x) = 0, we have:

-x + 36 = 0

Adding x to both sides, we get:

36 = x

Therefore, the only value of x for which f(x) = 0 is x = 36. So, f(x) = -x + 36 does not have a real root, since there is no value of x that makes the function equal to zero.
